LETTER FROM THE EDITOR-IN-CHIEF

“You Can’t Always Get What You Want…”“…but You Get What You Need!”

Love, politics and drugs were the subjects ofMick Jagger’s self-reflection in the 1960s rockanthem, “You Can’t Always Get What You

Want.” Since then, the song’s chorus has beenreproduced and re-purposed into every-thing from parenting advice to sociology lec-

tures. Mick’s personal struggles with drugs and other temptationsare referenced frequently as the artistic purpose of the song, andwhile he may not have intended greater ideological meaning, I donot hesitate to declare that the lyrics have had a lasting impressionon society and its struggles with selfishness and greed. Parallels canbe drawn to all aspects of life in a modern, democratic world. We areonly now beginning to appreciate the inherent cost of freedom ina diverse and global world, let alone in healthcare.

Clinical medicine was, for most of its history, a “technocracy”:A professional elite that “ruled” by virtue of being the most knowl-edgeable and skilled. “Laws” of clinical practice were fairly clearand patients deferred decision-making to the “house of medi-cine” and its physician representatives. I needn’t tell anyone read-ing this editorial how times have changed. Medicine has beentransformed into a practice entirely driven by the agendas ofinterest groups far more powerful and numerous than the“house of medicine.” Physicians, on the other hand, have beenrendered nearly impotent. Governmental agencies representingthe perceived “interests” of patients have rolled out more regu-lations in healthcare than for nearly any other industry at a costof hundreds of billions of dollars each year.

As I noted in a previous column, there has been no study todate that has examined whether we have obtained an ounce ofquality or cost savings from these efforts. It is undeniable, how-ever, that there have been considerable hard and soft costs thathave been paid for mostly by well-meaning physicians. And if thatwasn’t enough, professional independence and authority hasbeen further hijacked by other powerful private interests likeinsurance companies, lawyers, hospitals, and drug and devicecompanies.

And now, for the most powerful and potentially dangerous inter-est group of them all: Our patients (cringe). There is no greater follythan to call out our patients as contributing to the ills of medicine,but let’s face it, in a democratic society, it is the desires of the peo-ple that ultimately drive the political and corporate agenda. More

than ever, our patients have insatiable and unrealisticdesires…err…demands that render the physician almost paralyzedin practice. Doctors spend an increasing amount of time negotiatingwith patients…what medications to prescribe, what tests to do, whatprocedures to perform. While a wonderful ideal in theory, the con-cept of shared decision-making is, perhaps, the most unrealistic expec-tation of medicine today.

Here’s why:The process of medical decision-making is the most revered partof clinical medicine. It is the convergence of the physician’sfund of knowledge with the clinical presentation, patient history,epidemiology, pre-test probability, and evaluation of risk and ben-efit. In other words, medical decision-making is, perhaps, toocomplex to be truly “shared.” What you get instead is a jumbledand distracted process where nobody wins. After all, how can youhave “shared” decision-making with a patient “partner” who hasno appetite for uncertainty and, understandably, cannot thinkobjectively about his or her problem?

The American desire to control one’s own destiny and the deci-sions that impact them is powerful indeed. We view authorityover these decisions with great skepticism. As it pertains to ourhealthcare, we want our antibiotics and our MRIs when wewant them, we want our knee arthroscopies regardless of proof,and we want it all without any risk of complication. We want itnow and, unfortunately, we don’t care if our “wants” are directlycontributing to a broken system on the verge of collapse that can-not provide effective or efficient healthcare to its people. This isthe system we want. Well, you can’t always get what you want,America. If only we could get what we need!

Hail the Technocracy! ■

9 Strategies for AvoidingDrug-Drug Interactions inUrgent CareWith the increasing number of drugs on the market, patients are more andmore likely to be taking multiple medications. Urgent care providers need tobe alert for potential interactions when changing or adding to a patient’sdrug therapy.

Maya Heck, MS1, and John Shufeldt, MD, JD, MBA, FACEP

CLINICAL

IN THE NEXT ISSUE OF JUCMAccording to one study, 91% of parents suffer from “feverphobia”—the erroneous belief that fever alone couldhurt their child. It’s not surprising, then, that fever is oneof the most common chief complaints in pediatricpatients presenting at urgent care centers. In the vastmajority of these cases, the source of the fever will bediscovered on physical exam or the explanation will bea self-limited viral illness. The challenge for urgent careproviders is to identify the pediatric patient with feverwho is at high risk of a serious bacterial infection (SBI)such as urinary tract infection, pneumonia, bac-teremia, or meningitis. Next month’s cover story offersrecommendations for an age-based approach to lab-oratory testing that is rigorous yet ensures prompt iden-tification of the “not well” pediatric patient with feverand appropriate evaluation of the “well” pediatric patientto rule out any possible SBIs.

22Chronic ExertionalCompartment SyndromeRunners who train too much too soon riskserious injury. Prompt and thorough evaluationis necessary to spot CECS masquerading as “shinsplints.”

J U C M C O N T R I B U T O R S

With use of multiple drug therapiesbecoming more common andpatients’ medication lists grow-

ing longer, the number cases of drug-drug interactions seen by urgent care providers is increasing.Nineteen percent of all hospitals injuries are caused by adversedrug events, most of which involve common medications andmany of which are drug-drug interactions. This month’s coverstory, by Maya Heck, MD, and John Shufeldt, MD, JD, MBA,FACEP, reviews the risk factors for drug interactions with war-farin, antibiotics, oral contraceptives, statins, and selective sero-tonin reuptake inhibitors. It’s not possible for an urgent careprovider to remember all potential drug interactions but it is cru-cial to maintain a high level of suspicion when making changesor additions to a patient’s medications, and to thoroughlyreview existing medications when prescribing something new.

Millions of people worldwide runas a form of exercise and training forcompetitive events from 5K races toultramarathons is no longer unusual.

Half of regular runners find themselves injured each year andmany such complaints are a result of overexertion or overuse.In this month’s case report, Matthew Speer and John Shufeldt,MD, JD, MBA, FACEP, underscore the importance of prompt andthorough evaluation of even the most physically fit, youngpatient who presents with complaints associated with running.Those “shin splints” may be chronic exertional compartmentsyndrome (CECS) caused by repetitive microtrauma. Withoutappropriate treatment, CECS can cause complications thatwould put an abrupt end to a patient’s running career.

Offering medical interpretation services is a requirement forurgent care centers that treat patients whosehealth care is covered by federally funded pro-grams or who are hearing- or vision-impaired.Several methods of reliable medical interpreta-tion are available, each of which can affect the quality of thepatient experience and clinical outcomes. As Alan A. Ayers,MBA, MAcc, describes in this month’s practice managementarticle, some types of medical interpretation are quicker,whereas as others are more accurate, and still others are moreexpensive. How to choose? The author counsels taking intoconsideration the frequency or likelihood of non-English-speaking patients, the diversity of languages presenting, andthe language skills and training of providers and staff.

Mr. Ayers is Associate Editor, Practice Management, JUCM,Content Advisor, Urgent Care Association of America, andVice President, Concentra Urgent Care.

Also in this issue:John Shufeldt, MD, JD, MBA, FACEP, discusses employeetheft. The key message here is to not let blind loyalty lull you intoa false sense of security.

Nahum Kovalski, BSc, MDCM, reviews new abstracts on lit-erature germane to the urgent care clinician, including studiesof statins in prevention of urinary tract infection, pediatric appen-dicitis, and panic disorder and atrial fibrillation.

In Coding Q&A, David Stern, MD, CPC, discusses modifier -25 and urgent care codes.

Consider This Patient Scenario:

A28-year-old woman who says she is a traveling nursecurrently on an assignment at a nearby hospital pres-ents to an urgent care clinic with a complaint of fre-

quency, urgency and burning on urination. She is goingon a ski trip and wants to ensure that she clears up whatshe believes is a urinary tract infection (UTI) beforeleaving on vacation. The patient denies vomiting butcomplains of intermittent nausea. She denies flankpain, vaginal discharge, and the possibility of preg-nancy. Interestingly, the woman does tell the providerthat she was on birth control pills (BCPs) but developeda blood clot in her thigh and then a pulmonaryembolism (PE) after flying cross country. She has beenon warfarin for the past 3 months and her last Interna-tional Normalized Ratio (INR) (yesterday) was 2.4. Alsonoteworthy is that the woman has had a significantreaction to penicillin-based antibiotics in the past.

The urgent care provider orders a urinalysis (UA) andurine chorionic gonadotrophin (UCG) test. On exami-nation, the patient’s vital signs are as follows: BP 120/72

P 88R 16T 39.2Pain Scale 4/10.

The woman’s exam is unremarkable, other than someslight suprapubic tenderness. Her urine dipstick comesback with 4+ leukocytes and is nitrite positive and herUCG is negative.

She is appropriately diagnosed with a UTI. Noting thepatient’s allergy to penicillin, the provider prescribestrimethoprim and sulfamethoxazole (TMP-SMX) andpyridium and discharges the patient home.

A few days later, sadly, the patient was flown into a trau-ma center in Denver unresponsive after a seemingly minorhead injury, which occurred during a snowboarding acci-dent while she was wearing a helmet. On admission, thewoman’s Glasgow Coma Scale score was 3 and her INRwas 8.2. Computed tomography scan revealed a massiveepidural hematoma causing herniation. Her familyremoved her from life support after donating her organs.

The Rise of Drug-Drug InteractionsIn 2012, the FDA approved 35 new medications 1, and inter-actions between medications have been increasinglyreported.2 As patients’ medication lists become longer andthe use of multiple drug therapies becomes more frequent,it is increasingly important for the provider to consider druginteractions and question the safety of drug regimens.Among other risk factors, the frequency of drug-drug inter-actions increases most significantly with the number of med-ications in use. Adverse drug events, including drug-druginteractions, account for 19% of all hospital injuries3 andmost involve commonly-used medications. By underscor-ing the potential for drug interactions with warfarin, as illus-trated by the patient scenario above, this article highlightsthe importance of recognizing drug-drug interactions andconsidering the factors that increase their risk.

Drug Interactions with WarfarinWarfarin is the anticoagulant most widely prescribed inNorth America4 and interactions leading to over-antico-agulation, under-coagulation, or increased bleeding are welldescribed for an increasingly large number of drugs takenconcomitantly. Warfarin and other vitamin K antagonists(acenocoumarol, phenprocoumon, fluindione) are pre-scribed as oral anticoagulants for thrombosis prophylax-is in many clinical settings. This class of drugs act by inhibit-ing the synthesis of vitamin K, a vitamin necessary for acti-vation of coagulation factors. Warfarin is known to havea narrow therapeutic range and dose response and result-ant INR vary greatly between individuals. Especiallynotable are the interactions between warfarin and antibi-otics, acetaminophen, aspirin, and nonsteroidal anti-inflam-matory drugs (NSAIDs) (Table 1).

For urgent care providers, obtaining a thorough his-tory is the best way to prevent poor outcomes due tounforeseen drug-drug interactions. It is important toreview medication lists and consider possible drug-druginteractions before prescribing new medications topatients using warfarin.

AntibioticsBy reducing vitamin K levels in the gut flora, antibi-otics can heighten the effects produced by warfarin,leading to over-anticoagulation.5 Another mechanismrecognized for increased bleeding with warfarin isinhibition of its metabolism. Drugs that have beenfound to inhibit warfarin metabolism include azithro -mycin, cipro floxacin (Cipro), clarithromycin (Biaxin),erythromycin, metronidazole (Flagyl) and TMP-SMX(Bactrim, Septra).2

Upon its release in 1993, azithromycin was origi-nally believed to be free of interaction with warfarin.However, in 2009, the FDA revised its label on the pack-age insert to read, “Although, in a study of 22 healthymen, a 5-day course of azithromycin did not affect theprothrombin time from a subsequently administereddose of warfarin, spontaneous post-marketing reportssuggest that concomitant administration of azithro -mycin may potentiate the effects of oral anticoagu-lants. Prothrombin times should be carefully moni-tored while patients are receiving azithromycin andoral anticoagulants concomitantly.”6

In a population-based cohort study of patients usingacenocoumarol or phenprocoumon, several antibioticsstrongly increased the risk of over-anticoagulation; 351of the 1,124 patients in the cohort developed an INR of6.0.7 In the study, TMP-SMX was associated with the

greatest risk of over-anticoagulation.7 Given these find-ings, urgent care providers should select an alternativeantibiotic that has not been implicated in over-antico-agulation for patients who are taking warfarin.

AcetaminophenAcetaminophen is the most frequently ingested medica-tion in the United States2 and it has been recognized asanother cause of over-anticoagulation. In one study, highdoses of acetaminophen (9100 mg/week or just 3 extra-strength tablets per day) were found to be associated witha 10-fold increased risk of having an INR > 6.0.8 In a casereport, acetaminophen was found to enhance the effectof warfarin but the elevation may only be apparent aftera few days of acetaminophen therapy.9

Nonsteroidal Anti-Inflammatory DrugsConcomitant use of NSAIDs and warfarin increases riskof bleeding and should be avoided. However, in a studyassessing rates of hospitalization for gastrointestinal bleed-ing, the selective cyclooxygenase-2 (COX-2) inhibitorscelecoxib (Celebrex) and rofecoxib (Vioxx) were prefer-able to nonselective NSAIDs in patients who requiredNSAIDs.10 COX-2 inhibitors have reduced antiplateletproperties compared with nonselective NSAIDs.

Also noteworthy is that the particular need to avoid useof nonselective NSAIDs in patients who are at increasedrisk of NSAID gastropathy. Factors including age > 65, his-tory of peptic ulcer disease, exposure to systemic steroidtherapy, heavy smoking, or high usage of NSAIDs are redflags for heightened risk of gastropathy.2

Counseling patients about the risks of bleeding asso-ciated with concomitant therapy with warfarin andNSAIDs and close monitoring of INR values are impor-tant to minimize risk of bleeding.

Monitoring INR ValuesAccording to UpToDate, the guidelines for returningINR values to the patient’s normal range are as follows:

� INR <5.0 without bleeding: If the INR is above nor-mal range but less than 5.0 with no significantbleeding, it is recommended that the next dosageof warfarin be omitted or the maintenance dose bereduced.11

� INR 5.0-9.0 without bleeding: If there is no signif-icant bleeding, there is approximately a 1% risk ofa major hemorrhage occurring in the next 30 days.Two of the options for reducing INR values are: a. Stopping warfarin temporarily. b. Stopping warfarin temporarily and adding a dose

of 1 to 2.5 mg of oral vitamin K. This is a fasterapproach to correct excessive anticoagulation.11

� INR >9.0 without bleeding: If there is no significantbleeding with these INR values, warfarin should beomitted and 2.5 to 5 mg of oral vitamin K shouldbe administered. INR values should be closely mon-itored for 24 to 48 hours and vitamin K treatmentshould be repeated as necessary.11

� Elevated INR with minimal bleeding: Although thereare no precise guidelines for this situation, the deci-sion is based upon clinical judgment, INR level, andcurrent extent/risk of worsening of the bleeding.Providers may choose to follow treatment plans forINR >9.0 without bleeding, or opt for more emergentcare depending on the severity of the case.11

Drug Interactions with AntibioticsFluoroquinolonesAntibiotics can interact with other drugs via multiplemechanisms; this article highlights significant interac-tions involving the fluoroquinolone class of antibi-

otics. Agents containing divalent cations and trivalentcations can reduce absorption of fluoroquinolonesthrough creation of insoluble complexes in the gut,which results in failure of treatment. Cations are pres-ent in many medications and over-the-counter prod-ucts, and it has been found that absorption of fluoro-quinolones is reduced by 60% to 70% when they aretaken concomitant with products containing divalentor trivalent cations.2

The divalent cation calcium is present in Caltrate, Cit-racal, Os-Cal, PhosLo, Titralac, and Tums, whereas thedivalent cation magnesium is found in Almora, Citrateof Magnesia, Mag-Ox 400, Milk of Magnesia, Slow-Mag,and Uro-Mag. Aluminum and ferrous sulfate are triva-lent cations that can be found in Alu-Cap, AlternaGel,Amphojel, Basalje and Feosol, Fergon, Niferex, Nu-Iron,and Slow Fe, respectively.2

Ciprofloxacin, enoxacin, lomefloxacin, norfloxacin,and ofloxacin are affected by divalent and trivalentcations found in antacids. Sucralfate, containing thetrivalent cation aluminum, has been found to inhibit

absorption of several quinolones, including cipro -floxacin and norfloxacin.12

It is important to advise patients to stop taking prod-ucts containing divalent or trivalent cations until theirfluoroquinolone therapy has ceased.2 It has been shownthat inhibition of absorption can be avoided by admin-istering the antibiotic at least 2 hours before or 6 hoursafter the cation.12

TheophyllineQuinolones inhibit metabolism of theophylline, whichresults in an increase in theophylline serum concentra-tions and subsequent reactions, leading to tachycardia,nausea, and seizures.12 Quinolone antibiotics exhibit awide range of inhibition: Enoxacin can result in a 65%reduction of theophylline clearance whereas cipro -floxacin inhibits by about 30%. Norfloxacin, ofloxacin,and lomefloxacin have been found to produce only aminimal effect.12

Patients with the upper normal limits of theophyllineserum concentrations are more likely to develop thesetypes of effects.12 This is an important factor to considerwhen determining whether the addition of a quinoloneis advisable. Note: It can take 2 to 3 days after the com-bination of quinolone and theophylline for the effectsto become pronounced, therefore, patients should bemonitored for signs and symptoms of toxicity.

Drug Interactions with Oral ContraceptivesAntibioticsClinical studies have not been demonstrative of a con-sistent effect of antibiotics on the decreased effectivenessof oral contraceptives (OCs), and concomitant use isdebatable. Given the low frequency of this drug-druginteraction, it is difficult to differentiate a pregnancy dueto the antibiotic from the expected failure rate.2

Rifampin can impair the effectiveness of OCs because ofits ability to increase activity of hepatic enzymes, whichare involved in estrogen metabolism.2 Concomitantuse of rifampin and OCs can lead to breakthroughbleeding and potentially an increased risk of pregnancy.

Although pharmacokinetic studies of other antibioticssuch as tetracycline and penicillin derivatives have notshown any systematic interactions with OCs, individualpatients have been found to have decreased plasmaconcentrations of ethinyl estradiol. It is theorized thatany interaction between OCs and antibiotics mayinvolve ethinyl estradiol.

An analysis of 167 articles on drug interactionsbetween antibiotics and OCs resulting in contraceptive

failure found that approximately 20% of women report-ing to family planning or abortion clinics were takingantibiotics and OCs concomitantly.13 However, a retro-spective study of 365 patients who were co-administeredOCs and an antibiotic showed only a small but insignif-icant increase in risk of pregnancy.2

According to the American College of Obstetricians andGynecologists Committee Opinion on medical eligibil-ity criteria for contraceptive use, there is no restrictionon use of OCs with broad spectrum antibiotics, antifi-ungals, or antiparasitics. However, with regards torifampicin or rifabutin therapy, the risk of pregnancy wasfound to outweigh the advantages of using OCs as a birthcontrol method.14

Take home point: Concomitant use of broad spectrumantibiotics and OCs is considered to be a safe practice. How-ever, urgent care providers may want to encourage patients onOCs to use back-up contraception during rifampicin therapy.

Antiepileptic DrugsPrescription of OCs to women with epilepsy is fairlycommon, despite the knowledge that concomitant usemay reduce the pill’s efficacy.15 Antiepileptic drugs(AEDs) that have been shown to induce metabolism ofthe steroidal components of the pill include carba-mazepine, felbamate, oxcarbazepine, lamotrigine, phe-nobarbital, phenytoin, primidone, and topiramate.

However, the magnitude of interaction dependson the dosage of the AED. For example, topiramatedoes not affect serum norethisterone and ethinylestradiol levels at dosages up to 100 mg per day butdecreases serum norethisterone consistently at higherdoses.15 Likewise, carbamazepine 600 mg per dayreduces serum levels by 50%. Gabapentin, levetirac-etam, pregabalin, tiagabine, valproate, vigabatrin, andzonisamide have not been reported to interact withsteroid OCs.15

Take home point: the best way to avoid complications withthis drug-drug interaction is to choose an AED that is notknown to interact with OCs.

Drug Interactions With ‘Statins’Statins are effective in treatment of hypercholesterolemiabecause of their ability to reduce low-density lipoproteincholesterol levels. However, there are many drugs that cre-ate adverse reactions when taken concomitant withstatins; generally, the risk of drug-drug interactions is dose-dependent. Because of the likelihood that patients receiv-ing statin therapy are elderly and may be on multiple otherdrugs for comorbid conditions such as heart disease or

hypertension, it is especially important to be aware of statin-drug interactions in these situations.

Drugs that raise statin concentrations in the bloodand can increase risk of adverse interactions such asmyopathy include immunosuppressant drugs, macro -lides, fibrates, protease inhibitors, azole antifungals,warfarin, and digoxin.16 For example, one studyreported myopathy incidence of 2%, 5% and 28% inpatients receiving lovastatin therapy with niacin,gemfibrozil and cyclosporine plus gemfibrozil, respec-tively.16 It is important to be aware of CYP3A4inhibitors when considering co-administration; a sys-tematic review of statin safety including data from 20randomized controlled trials showed that 60% of casesof rhabdomyolysis in patients receiving simvastatin,lovastatin or atorvastatin involved co-administrationof CYP3A4 inhibitors, and 19% involved co-adminis-tration of fibrates.16

General InteractionsVerapamil and diltiazem have been shown to increase

simvastatin plasma concentration up to fourfold, and dil-tiazem was also found to have the same effect with con-comitant lovastatin therapy.16 Statin drug-drug interac-tions with warfarin are well documented, and anelevated INR is a concern with warfarin and variousstatins (fluvastatin, lovastatin, and simvastatin). Antibi-otics that are CYP3A4 inhibitors, such as erythromycinand clarithromycin, have been reported to increaseplasma concentration of simvastatin and lovastatin.Conversely, the antibiotic rifampicin has been demon-strated to decrease plasma levels of statins includingatorvastatin, simvastatin, pravastatin, and fluvastatin.16

Azole antifungal drugs, such as itraconazole and etocona-zole, have been shown to increase the availability of ator-vastatin, simvastatin, lovastatin, and rosuvastatin.16

FibratesOf special importance is the recognition of fibrate-statin interactions. Gemfibrozil has been shown tointeract with atorvastatin, simvastatin, lovastatin,pravastatin, and rosuvastatin. However, bezafibrate,

clofibrate and fenofibrate have also been implicated incases of rhabdomyolysis when combined with statins.Because of the well-documented dangerous interac-tions with fibrate, statin-fibrate combination therapyshould be reserved for patients with severe hyperlipi-demia.16 In addition, it is also important to considerother factors, such as age, gender, diabetes, andhypothyroidism that may make a patient more suscep-tible to statin-induced myopathy.

Drug-drug interactions with statins are extensive, andonly a few examples have been highlighted in this review.Take care in co-administering statins with the drugs men-tioned above: immunosuppressant drugs, macrolides,fibrates, protease inhibitors, azole antifungals, war-farin, and digoxin.

Interactions With the ‘New Generation’ of SSRIsDrug interactions with tricyclic antidepressants (TCAs)and monoamine oxidase inhibitors (MAOIs) have beenwell documented. Since the advent of selective serotoninreuptake inhibitors (SSRIs), newer classes of antidepres-sants have been widely adopted due to their relative safe-ty compared with previous antidepressants. Eventhough SSRIs are reportedly safer than the “first gener-ation” of antidepressants, drug-drug interactions are stillan issue because of metabolism by the cytochrome 450system in the liver. The concomitant use of SSRIs anddrugs that are also metabolized by this system can leadto increased serum levels of these drugs. This article willhighlight the recently documented interactions with the“new generation” of SSRIs, including fluoxetine, citalo-pram, and paroxetine.

FluoxetineFluoxetine (FLU) has a long half-life (1-4 days) and, forthat reason, it has a high risk of interacting with otherdrugs. Plasma levels can be significant even weeks afterdiscontinuation of FLU therapy, so care should be takenwith administration of any new drug to a patient tak-ing FLU. Increased plasma levels of clozapine, lithium,and olanzapine have been observed with co-adminis-tration. In addition, FLU increases the half–life ofdiazepam. FLU has also shown to be an inhibitor of MAOenzymes, therefore, care should be taken when consid-ering co-administration with MAOIs.17

CitalopramCitalopram is used to treat symptoms of major depressionand it is also being evaluated in treatment of some anx-iety disorders. Concomitant use of antifungal medicationsand erythromycin can increase levels of citalopram. In addi-tion, administration of citalopram with MAOIs cancause serotonin syndrome, characterized by at least threeof the following symptoms: diarrhea, fever, sweating, moodor behavior changes, overactive reflexes, fast heart rate, rest-lessness, shivering or shaking.17

ParoxetineParoxetine is probably the most selective SSRI, relativelysafe regarding cardiovascular effects, and is often used inelderly patients. About 95% of absorbed paroxetine isbound to plasma proteins, making interactions with otherbound drugs such as clozapine and oral anticoagulants like-ly. Trials have shown an increase in bleeding after pro-longed co-administration of paroxetine and warfarin.17

Patient HistoryA detailed history is the most effective way to preventdrug-drug interactions. Often, in the urgent care set-ting, it is difficult to obtain the entirety of a patient’smedical record. A thorough history can help preventgaps in the medical record. Important factors to con-sider when reviewing the medication list include thepatient’s age, the dosage of medications, and his/herusage of antibiotics. Although the urgent care providerin the patient scenario above appropriately prescribedan antibiotic other than penicillin because of thepatient’s allergy, he did not recognize the interactionsbetween warfarin and antibiotics. It is just as importantto be aware of potential drug-drug interactions to avoidpreventable complications. Table 2 suggests alterna-tive antibiotics for common urgent care presentationsin patients on warfarin therapy.

AgeAge is an important factor to consider in prevention ofdrug-drug interactions. Factors including frailty, mem-ory loss, and use of many medications all contribute tothe increased incidence of drug-related issues in olderindividuals.19 The prevalence of multiple chronic med-ical conditions requiring many different therapeuticprotocols increases with old age, amplifying the chanceof adverse drug-drug interactions.

DosageAdverse drug events, including dangerous drug-druginteractions, are commonly dose-related. To preventdosage-related drug interactions, it is important as aprovider to be aware of a number of factors that con-

tribute to drug maintenance, including a patient’snutritional status, degree of compliance, hepatic andrenal function, and potential genetic factors contribut-ing to the individual’s response to a particular drug.20

ConclusionWith the increasing number of drugs on the marketand the prevalence of lengthy medication lists, it isunrealistic to expect an urgent care provider to remem-ber all potential drug interactions. However, it is nec-essary to maintain a high level of suspicion when mak-ing changes or additions to a patient’s medications.Care must be taken to thoroughly review existing med-ications—both conventional and nonconventional—when prescribing a new medication. Extra precautionsshould be taken when treating elderly patients whomay be on multiple drug therapies. ■

Overview

Running is one of the world’s most popular exercises,with millions across the globe participating and train-ing for events from 5K races to ultramarathons of over

100 miles. Despite the fact that more than 10 millionpeople run over 100 days per year, more than half of reg-ular runners find themselves injured each year. More-over, many such injuries result from overexertion oroveruse.

Chronic exertional compartment syndrome (CECS),which often masquerades as shin splints, is one exam-ple of a running-related injury that results from repeti-tive microtrauma. Because endurance athletes typi-cally avoid any sort of treatment that involves rest,immediate recognition of CECS is of utmost impor-tance to avoid further complications. As illustrated bythe case presented here, conducting a proper examina-tion with attention to both history and symptoms willensure an accurate diagnosis and proper treatment.

Case PresentationA 19-year-old male long-distance runner presents withsharp, cramping pain in the anterior compartment ofhis lower right leg that gradually intensifies duringphysical exertion, similar to that associated with medialtibial stress syndrome (shin splints). He reports that

the pain generally subsides within approximately 25 to30 minutes after he ceases physical activity. The discom-fort is associated with some paresthesia and numbnessbilaterally down the anterior compartment of each leg(Figure 1).

The patient has been seen twice in the urgent care set-ting with the same symptoms, which were diagnosedboth times as shin splits. The treatment recommended

Case Report

was scaling down the patient’s weekly mileage, icing theaffected area, and taking ibuprofen or acetaminophendaily until the swelling and pain subsided. The patientreports that the pain and other symptoms have persistedand now linger longer after each run.

Labs/ImagingMeasurement of compartment pressure with the StrykerIntra-compartmental Pressure Monitor is actually quiteeasy despite the fact that it is considered beyond thescope of many urgent care centers. In this case, meas-urement of compartment pressure in the patient’s lowerleg was necessary to make a definitive diagnosis becausehis history and physical examination suggested CECS.Such measurements can be done at an urgent care cen-ter or an emergency department or be performed by anorthopedist.

Measurements taken with and without exercise areconsidered to be the gold standard for diagnosis of

CECS. Proposed by Pedowitz et al, the criteria for con-firmation of CECS in the leg are as follows:

� A pre-exercise/rest pressure 15 mm Hg or higher� A 1-minute post-exercise pressure 30 mm Hg or

higher� A 5-minute post-exercise pressure 20 mm Hg or

higher

Although Pedowitz suggests that only one of theabove criteria are necessary to confirm a CECS diagno-sis, it should be noted that the confidence level increaseswith the number of criteria met. The following equip-ment is necessary to accurately measure the pressure ina given compartment:

� Stryker Intra-Compartmental Pressure Monitor System� Syringe, pre-filled with saline� Side-port needle� Diaphragm chamber� Arterial line transducer system

� Intracompartment needle� High-pressure tubing� Pressure transducer with cable� Pressure monitor/module� Sterile saline� Variable-height transducer stand� Two 3-way stopcocks� Syringe, 20 mL

Measurement TechniqueThe technique used for measuring compartment pres-sure varies greatly depending on the compartmentbeing tested. For purposes of this case study, we willdescribe the technique for measuring pressures in theanterior compartment of the lower leg. In all cases,however, the following should be observed:

� The compartment to be measured (the anteriorcompartment of the lower leg, in this case) shouldbe at the same level as the heart;

� The patient and the corresponding compartmentshould be positioned such that the needle is intro-duced perpendicularly into the compartment; and

� The skin at the site of insertion should be properlyprepared as for any sterile procedure and localanesthesia should be administered.

Anterior Compartment TechniqueWith the patient supine, palpate the anterior border ofthe tibia at the level of the junction of the proximal andmiddle thirds of the lower leg. Identify the needle entrypoint 1-cm lateral to the anterior border of the tibia. Ori-ent the needle so that it is perpendicular to the skin andinsert it to a depth of 1 to 3 cm. The most common errorwith both the Stryker monitor set and the arterial linetransducer system is depressing the syringe plunger tooquickly. This may give a transient falsely elevated read-ing. Another source of error with either system isobstruction of the needle with a plug of tissue if thesyringe plunger is pulled back.

ResultsCompartment measurements of the patient’s left legproduced the following results:

� A pre-exercise/rest pressure of 18 mm Hg� A 1-minute post-exercise pressure of 35 mm Hg� A 5-minute post-exercise pressure of 24 mm Hg

Alternatively, the pressures in the patient’s right legwere as follows:

� A pre-exercise/rest pressure of 21 mm Hg

� A 1-minute post-exercise pressure of 41 mm Hg� A 5-minute post-exercise pressure of 32 mm Hg

Diagnosis and TreatmentBecause this patient met all three pressure criteria, hiswas a classic presentation of bilateral CECS. Referralwas made to an orthopedic surgeon for scheduling of anelective fasciotomy.

A few key factors underscored the differential diagno-sis. A tibial stress fracture or shin splints initially couldbe ruled out because the patient’s pain ceased approxi-mately 25 to 30 minutes after physical exertion. Focaltenderness is typical of tendinopathy, which can be seenby testing various muscle groups at rest. A bone scan andmagnetic resonance imaging would help to rule out astress fracture, stress reaction, and any possible nerveentrapment.

DiscussionOnce CECS is diagnosed, the treatment most likely to

return a patient to his or herformer level of physical fitnessis surgery. Fasciotomy (Fig-ure 2) typically is necessaryto allow the muscle to expandmore within the compart-ment, which facilitates regu-lated flow of oxygen-richblood throughout the lowerleg. The procedure can be per-formed in one of a four ways:(1) open fasciotomy with 1 or2 incisions; (2), minimally invasive subcutaneous fascioto-my through 1 or 2 incisions; (3), partial fasciectomy; or(3) subcutaneous endoscopic fasciotomy, which can bedone with and or without use of balloon dissectors.

An open fasciotomy involves 1 to 2 large incisionsthrough which fascial tissue is cut. Minimally invasivesubcutaneous fasciotomy involves incision of fasciablindly via small skin incision(s). A portion of the fas-cia is removed in fasciotomy with partial faciectomy. Insubcutaneous endoscopic fasciotomy, use of a balloondissector creates an optical cavity through which the fas-cia can be visualized and space in which to perform dis-section with endoscopic equipment.

Although surgery is the most effective treatment forCECS, cessation of the inciting physical activity wouldalso lead to lessening or disappearance of a patient’ssymptoms. Because this condition typically occurs inendurance athletes, however, patients are unlikely to bewilling to completely forgo their former level of activity.That, coupled with the fact that any nonsurgical treat-ment or rehabilitation would fail to truly alleviate anymuscle ischemia as a result of reduced blood flow, givesweight to surgical intervention as treatment of choice.

SummaryChronic exertional compartment syndrome is an exer-cise-induced neuromuscular condition characterized bypain due to repetitive microtrauma, typically in thelower legs (although it can also been found in the fore-arms). Stereotypically seen in young endurance ath-letes, CECS often masquerades as shin splints and ischronically misdiagnosed in urgent care centers andemergency departments.

In patients who present with symptoms of CECS,proper diagnosis requires measurement of compart-ment pressures both before and during exercise. If thesemeasurements confirm the diagnosis, a patient shouldbe referred to an orthopedic surgeon for a fasciotomy.

The alternative is cessationof the inciting activity.

Abrupt changes in a train-ing regimen often lead toinjuries such as CECS. Whenincreasing training volumeor training intensity, patientsshould be counseled to grad-ually increase the volume orintensity (typically a 10%increase per week is advised).Limiting weekly volume to

approximately 40 miles will reduce the number ofinjuries. Moreover, it is advisable to run no more than4 or 5 days per week, with one long run (13+ miles) tak-ing place only once every 14 days.

If the patient described here had continued his train-ing regimen on the assumption that he was sufferingshin splints, a vicious cycle of worsening tissue perfusioncould have resulted in the loss of one or both lower legs,thus forcing an abrupt end to his running career. ■

The demographics of the United States are rapidlychanging. Today a language other than English isspoken in 55 million households, 67% of which speak

Spanish, and an estimated 19% of Americans have Lim-ited English Proficiency (LEP).1,2 In places like SouthernCalifornia, over 200 languages are spoken and nation-ally, 1 in every 10 business transactions occurs in a lan-guage other than English.3 Over 1.2 million immi-grants, both documented and undocumented, moveinto the United States each year, and children born toimmigrants account for over 70% of populationincreases.4 Considering the proliferation of non-Englishspeakers who require healthcare in the United States, itshould come as no surprise that the availability of med-ical interpretation services is required by law.5

Legal Considerations for Urgent Care OperatorsWhile medical interpretation services have been shownto enhance patient compliance and follow-up whilesignificantly reducing chances for misdiagnosis, twofederal regulations affect how urgent care centers treatpatients with limited English proficiency or who have

hearing or sight difficulties:� Title VI of the Civil Rights Act; and � Title III of the Americans with Disabilities Act (ADA).

If an urgent care center receives any funds fromMedicare, Medicaid, Tricare or any other federal healthprogram, Title VI of the Civil Rights Act of 1964 requiresthat center to provide “equal access to treatment” in away that is “meaningfully understood by patients”—

both of which have been defined as including accom-modation for limited English proficiency as well as forphysical impairment.

Executive Order 13166, issued by President Clinton in2000, stipulates, “Any health facility that receives fed-eral monies must provide competent interpreter servicesfor all limited English proficient patients. In case ofrefusal to provide this service, federal monies can bedenied the facility.”6

In 2000, then President Bill Clinton emphasized theimportance of “meaningful understanding” in medicalsettings when his Executive Order 13166 expanded theprotections of Title VI to people with limited ability tounderstand English. In 2002, the Department of Healthand Human Services (HHS) followed up with its ownguidance regarding “meaningful access”7 that considersit discriminatory to deny services in a healthcare settingto beneficiaries of federal health care programs. “Effec-tive communication is critical for necessary health andhuman services,” said HHS, and “in many cases, LEPindividuals form a substantial portion of those encoun-tered in federally assisted programs.”

Further, according to Title III of the ADA,8 “no indi-vidual shall be discriminated against on the basis of dis-ability in the full and equal enjoyment of the goods,services, facilities, privileges, advantages, or accommo-dations…and that discrimination includes a failure tomake reasonable modifications in policies, practices,or procedures when such modifications are necessary toafford such goods, services, facilities, privileges, advan-tages, or accommodations to individuals with disabili-ties, unless the entity can demonstrate that makingsuch modification would fundamentally alter the natureof such goods, services, facilities, privileges, advantages,or accommodations.” The definition of public accom-modation specifically includes the “professional office ofa health care professional,” 42 U.S.C. §12181(7)(F).9

Under the ADA, urgent care centers must provide equalaccess to their services and one must assume that includespatient communication.

Steps to Offering Medical Interpretation ServicesUrgent care operators have several options for meetingthe requirement to communicate with patients in away they understand. If a center sees a large number ofpatients speaking the same non-English language, themost convenient and perhaps most cost-effective is touse the center’s staff to translate. This requires hiring bi-lingual receptionists, technicians and medical assistantsbut even better are bilingual nurses and doctors who can

treat patients without using a mediator. According tothe International Medical Interpreters Association(IMIA), bilingual staff are an investment in the patientexperience with “language discordant” patients 61 per-cent more likely to rate their providers as “fair” or“poor” compared with language-concordant patients.”10

However, bilingual clinicians are often difficult tofind and a full-time medical interpreter can earn $40,000or more per year—a heavy expense burden, even if alsosupporting the center as a receptionist or medical assis-tant. And what happens when, say, a clinic in SouthFlorida that employs providers and staff who are fluentin Spanish encounters a French-, Portuguese-, or Russian-speaking patient, which is common in Miami?

Because the interpreter will be speaking back andforth between two communicators, the most importantskill is to have fluency in both languages.

As a substitute for bilingual providers and staff, mostlarge cities have companies that can provide on-site face-to-face medical interpretation services in any number oflanguages. A trained medical interpreter is someone whohas been formally educated in medical interpretationand is not only sensitive to cultural nuances but also edu-cated in medical terminology. More often than not, med-ical interpreters are native speakers. The advantages of anin-person, experienced medical interpreter includepatient satisfaction, assurance that truthful informationis being conveyed, better understanding on behalf ofboth the patient and caregiver, decreased costs of diagnos-tic testing, and fewer preventable medical errors.11

Sign language interpreters help their clients a bit dif-ferently than do spoken language interpreters. Theyhave fluency in both English and American Sign Lan-guage (ASL), which has its own grammar. ASL is com-posed of signing, finger spelling, and specific body lan-guage. People with hearing difficulties may read speakerslips. Interpreters help lip-readers use oral interpreta-tion, which is mouthing the words carefully and dis-tinctly so that the person who is lip reading can under-stand more easily. They may use “cued speech” – handshapes near their mouth to give lip readers more infor-mation. They can also use body language and facialexpressions to communicate. For patients who are bothsight- and hearing-impaired, the interpreter will use“tactical signing”—signing into the patient’s hand sothat he/she can feel the communication.12

When an On-Site Interpreter Isn’t PossibleWhile the advantages of using “professional inter-preters” cannot be disputed, the on-demand nature of

urgent care and ebbs and flows in walk-in volume makeit impractical to have an interpreter physically present.And when family members and other non-profession-als (such as community activists or church representa-tives who arrive with the patient) are relied upon, therecan be an inherent lack of familiarity with medical ter-minology, word substitution or editing, or emotionsadded by the interpreter, which contribute to confusion,miscommunication, and medical mistakes.13 Introduc-ing non-professionals to the patient encounter can alsojeopardize patient privacy.

Depending on an urgent care center’s location, itmay see limited English proficiency patients severaltimes a day, once or twice a week, or once or twice ayear. The frequency with which a center encounters theneed for medical translation plays a large role in deter-mining which translation options balance demand,cost, and efficacy.

Given the impossibility of having bilingual staff tomeet every need that could arise at an urgent care cen-ter, the most practical methods of interpretation areflash cards containing common signs, telephonic, andvideo services.

First off, research casts doubt on the efficacy of flashcards for medical interpretation purposes. The odds ofmiscommunication using flash cards are high becausepointing to images lacks the specificity of spoken lan-guage and can convey any number of meanings. Basedon studies that trained interpreters are 70% less likely toerr than untrained interpreters,14 the most effectivesolution is the use of technology to “bring” a trainedinterpreter into the clinic.

Telephonic medical interpretation has been the fastestgrowing, and according to the IMIA,15 this method wastouted for use in facilities that dealt with many lan-guages, had infrequent need for translation services, orthat were located in outlying areas. Because encounterscan be conducted in an exam room with the clinician,patient and a speakerphone—telephonic translationpreserves patient confidentiality. Service providers areavailable 24 hours a day, 7 days a week, and supportalmost every language and dialect.

Telephone interpretation can be useful with patientswho speak uncommon languages or in emergencieswhen an in-person interpreter cannot be arranged. Butthe telephone interpreter cannot monitor and evaluatethe patient’s body language and facial expressions.Communication is more than words; patients lack med-ical lexicon so consider someone pointing to a body partto indicate where their pain originates or how it trav-

els.16 Using Internet technology, telephonic interpreta-tion can be coupled with a video feed, providing bothwords and gestures to the interpreter. Allowing forvisual cues not only improves the accuracy of transla-tion, but it can accommodate communication for thedeaf and hearing-impaired patients because sign lan-guage is easily communicated via video connection.

For most urgent care centers, a subscription to a tele-phonic or video medical interpretation service is a lowcost way to ensure compliance and preparedness, shoulda non-English-speaking or hearing-impaired patientshow up and require services.

ConclusionUrgent care centers are required to offer interpretationfor patients who are using federally funded programs topay for health care services as well as those who are hear-ing- or vision-impaired. To identify the best interpreta-tion method for your center, consider the frequency orlikelihood of non-English-speaking patients, the diver-sity of languages presenting, and the language skills andtraining of providers and staff. ■

Et tu, Brute?■ JOHN SHUFELDT, MD, JD, MBA, FACEP

In the past, when I have broached the topic of employee theftwith urgent care owners, their typical, somewhat indignant,response is, “My employees would never do that!” I really like

this answer because I really value loyalty – more than anything. In the film Ides of March, campaign manager Paul Zara (PhilipSeymour Hoffman) proclaims: “I value loyalty over every-thing.” Of course, he completely gets screwed (by his formeremployee) at the end of the movie but at least he can look him-self in the mirror every morning — so he has that going for him,which is nice!

Here’s the rub. If no employees would ever do this why isone out of three business failures in the United States the di-rect result of employee theft?1 Truth be told, this has happenedto me – twice. Both times the perpetrators were discovered andultimately fired. The first time we recovered the money($70,000); the second time was a much smaller amount andwe did not recover the money. Both of the employees went towork for competitors—and the second one sued us.

One trait common to medical providers is that we think peo-ple are honest and will generally do the right thing and, thatno one (particularly a trusted member of the team) wouldknowingly steal or be disloyal to us. Yet it happens all the time.

Here are some steps that will help you prevent employee theft:

Make the Right Hire Check references. “Had I known” should not be coming out ofyour mouth when you find out that your employee has beendishonest. Ask around about a prospective employee–and notjust the people someone has listed as references. Urgent caremedicine is a small community and chances are, someone youknow will know the prospective employee and give you astraight answer. In addition, if the job requires handling money,get the potential employee’s permission in writing to checkhis/her credit report.2 I am not sure you can draw any linear

conclusions but desperate times sometimes lead to desperatemeasures. In the same vein, doing a criminal backgroundcheck and verifying employment history is absolutely integral.

Trust your gut. Applicants who “trash talk“ a previous boss, leavewith little or no notice or state that previous co-workers did notlike them because of _____________(fill in the blank) should bea red flag. One caution: If an applicant discloses some personalinformation to you about a potential disability, marital status,pregnancy, religion, etc. you cannot refuse to hire him/her forthat reason. Be careful. I know of situations in which prospec-tive employees have related something on purpose just so thatif they weren’t hired they could claim it was due to the issuethey disclosed.

Keep notes during the hiring process. This way, if it goes “south”you will have something to fall back on to stimulate yourmemory. Occasionally, applicants will pad their resume ormake grandiose statements about their past. (I recently had anapplicant tell me she had a ride in an F-35, which I found in-teresting since a two seat F-35 has never been made. Wait,could she have meant an F-350 Ford? I better check my notes!Whew, she said “fly.”). Needless to say, she was not hired.

Institute a probationary period. A 90-day probationary period isalways a good way to “test drive” an employee for a period oftime and it allows the employee to “test drive” you and the com-pany. Another option is to make the initial hire as a consultantwith payment as a 1099 independent contractor. If no red flagsappear, the consultant can be hired as a full-time employee.

An Ounce of PreventionThere are a number of procedures and internal controls you caninstitute to make it more difficult for an employee to steal or

One rule of thumb is to separatecash collection functions from

payment and deposit functions.

embezzle from the practice. One rule of thumb is to separatecash collection functions from payment and deposit functions.(This is what caught me in the first episode). In addition, havethe bank statements mailed directly to you at a different ad-dress. If something does not seem correct, start researching it. Here are some additional internal control procedures:

Check bank statements. As discussed above, check them your-self and see where the funds are going. Look for odd patterns,vendors who don’t seem to have a role in health care, and un-explained fluctuations in deposits.

Monitor work hours and vacation time. One pattern I have wit-nessed is staying late, coming in on weekends, and irregularwork hours to help hide embezzlement. If you see someone“working hard” you are less likely to suspect him/her. However,this is typically when the embezzlement is taking place. In ad-dition, require employees to use their vacation days. Thatgives you some time to check their work. Rotating roles occa-sionally is a great way for employees to learn other aspects ofthe business. It keeps them on their toes and gives them per-spective on the entire organization. It also allows others to re-view their counterpart’s work. If an employee is reluctant tohave others review his/her work, that’s a red flag.

Know all parts of the business. Learning all aspects of the busi-ness is incredibly useful. This does not mean you have to be anexpert on everything. It simply means you have to have morethan a superficial understanding of the duties and processes.Knowing every role makes you nearly impervious to having thewool pulled over your eyes. In addition, it also sends a messageto the employees that you not only understand their role, butare able to check their work product and competence.

Manage cashflow. We already discussed having bank state-ments mailed to your home. You should also be making de-posits on a daily basis. This process includes keeping a deposit

ledger or log containing detailed information on the amount,the check number, patient receipts, etc.

Buy insurance. Discuss insurance that covers employee theft andembezzlement with your agent. In addition, you can use the in-surance carrier as the reason why you need to have all the othermechanisms in place.

Adopt a zero tolerance policy. Make sure that your employeesknow that you have a zero tolerance policy regarding embez-zlement and theft. Follow through with this policy by prosecut-ing any employee who steals. I made this mistake twice. Ishould have prosecuted both of the employees who embezzledfunds. Don’t threaten prosecution; don’t promise not to pros-ecute if they return the money—that is extortion. In moststates the court will require that the defendant pay restitutionto the victim so you will get your money back.

Red Flags 01. Missing accounting records or gaps.02. Discrepancies between deposits, receipts and bank

statements.03. Large petty cash funds that are not reconciled at the end

of every shift.04. Patient complaints about payment posting. “I paid a $50

co-pay but only received credit for $30.”05. Missing documents, invoices, receipts, etc.06. Overdue notices from creditors, vendors, etc.07. Employees insisting on doing a certain task or not want-

ing their work reviewed.08. Lack of separation of duties.09. Coming into the office late or not taking vacation days.10. Forming “too close” relationships with accounting

employees

As a leader, loyalty is a very admirable trait. However, do notlet blind loyalty lull you into a false sense of security whendealing with disloyal and dishonest employees. Put policiesand procedures in place so that you never have an, “et tuBrute” moment. ■

ABSTRACTS IN URGENT CARE

Statins for Prevention of UTIs? Key point: Statin use was significantly associated with reducedrisk of urinary tract infections overall and for a second episode,but not for a first episode. Citation: Pouwels KB, Visser ST, Hak E. Effect of pravastatinand fosinopril on recurrent urinary tract infections. J Antimi-crob Chemother. 2012 Oct 30; doi 10.1093/jac/dks419 [e-pubahead of print].

Recurrent urinary tract infections (UTIs) are common, especiallyamong women. Recent research has suggested that invasion ofbladder epithelial cells by uropathogenic Escherichia coli — andpersistence of these bacteria in quiescent intracellular reservoirs— may underlie such recurrence. Statins have been found to in-terfere with the bacterial invasion of cells, providing a rationalefor studying the clinical effect of statins on recurrent UTIs.

To this end, researchers in the Netherlands linked data fromPREVEND IT (a randomized trial to examine whether use ofpravastatin, fosinopril, or both might prevent cardiovascularand renal disease in nonhypertensive, nonhypercholesterolemicadults with microalbuminuria) with a large prescription data-base. Of the 864 trial participants who were randomized to astudy medication, 655 were eligible for the UTI analyses; aver-age follow-up was 3.8 years. Prescription of an antibiotic typ-ically administered for UTI treatment (nitrofurantoin, trimetho-prim, a sulfonamide) was considered a surrogate for infection.

In intent-to-treat analyses, pravastatin was associated with re-duced risk for UTIs both overall (relative risk, compared with place-bo, 0.43; 95% confidence interval, 0.21–0.88) and for a secondepisode, but not for a first one. The risk for a primary UTI was in-creased with fosinopril. UTI rates with combination therapy (pravas-tatin plus fosinopril) did not differ significantly from those withplacebo. Prescription rates for commonly prescribed drugs, andfor other antibiotics used to treat UTIs, were similar among groups.

Muscularity (and Behaviors Promoting It)Popular with Adolescents Key point: For all the talk about pediatric obesity, there arethose who are seeking to increase muscularity and keep theirweight down. Doctors NEED to learn about exercise and nutri-tion in order to guide these patients as well. And simply tellingthese kids that “steroids are bad” will not be very effective.Citations: Eisenberg ME, Wall M, Neumark-Sztainer D. Mus-cle-enhancing behaviors among adolescent girls and boys. Pe-diatrics. November 19, 2012. doi: 10.1542/peds.2012-0095and http://www.nytimes.com/2012/11/19/health/teenage-boys-worried-about-body-image-take-risks.html?_r=0.

Patients may ask about a Pediatrics study, covered on the frontpage of The New York Times, finding that more than 5% of ado-lescents use steroids to enhance muscle development. Researchers surveyed nearly 2800 students at 20 urban mid-dle and high schools about “muscle-enhancing behaviors,”including changed eating habits, exercise, protein powders, andsteroids and other substances.

The authors say that these behaviors are more frequent than

had been thought — especially among boys — and they adviseclinicians to discuss them with their patients in an attempt toavoid compulsive behaviors and future problems over time.

FDA Posts Adverse Event Reports Related toEnergy Drinks  Key point: 18 fatalities have been linked to the highly caffeinatedenergy drinks.Citation: http://www.fda.gov/Food/NewsEvents/ucm328536.htm.

The FDA publicly released the adverse event reports for four en-ergy drinks — 5-Hour Energy, Monster Energy, Rockstar Energy,and Red Bull. Thus far, 18 fatalities have been linked to the highlycaffeinated energy drinks (5 to Monster Energy, 13 to 5-Hour).

Some of the symptoms mentioned in the reports include in-creased heart rate, fatigue, vomiting, loss of consciousness, andcardiac and respiratory arrest. A federal report also found thatan energy drink was listed as a possible cause for over 13,000emergency room visits in 2009, The New York Times reports.

The FDA says that important information may be missingfrom the adverse event reports, making it “difficult ... to fullyevaluate” whether the energy drinks caused the injuries re-ported. Nevertheless, the agency advises consumers to consulta healthcare provider before using the products. ■

Pediatric Appendicitis: Ultrasound SensitivityIncreases with Symptom Duration  Key point: Ultrasound sensitivity increased from 81% in pa-tients with symptom duration <12 hours to 96% in those withsymptom duration 48 to 71 hours.Citation: Bachur RG, Dayan PS, Bajaj L, Macias CG, et al. Theeffect of abdominal pain duration on the accuracy of diag-nostic imaging for pediatric appendicitis.  Ann EmergMed. 2012;60(5):582-590.e3.

Investigators assessed the diagnostic performance of computedtomography (CT) and ultrasound in relation to symptom dura-tion in children (age range, 3 to 18 years) with suspected ap-pendicitis. This secondary analysis of a prospective study of pa-tients who presented to one of nine pediatric emergencydepartments included only patients with abdominal pain for <72hours. Symptom duration was categorized as <12 hours, 13 to24 hours, 25 to 36 hours, 37 to 48 hours, or 49 to 71 hours.

Of 1810 patients, 67% underwent CT, and 46% underwentultrasound. Overall, 680 patients (38%) had pathology-con-firmed appendicitis, and of these patients, 174 (26%) had per-forated appendicitis. The sensitivity of CT for diagnosing appen-dicitis did not differ significantly by symptom duration: 98%for <12 hours and 96% for 49 to 71 hours. However, the sensi-tivity of ultrasound increased significantly with symptom du-

ration: 81% for <12 hours versus 96% for 49 to 71 hours. Speci-ficity did not differ significantly by duration for either modal-ity, ranging from 90% to 96% for CT and 80% to 86% for ul-trasound. The risk of perforation significantly increased withsymptom duration, and in the subset of patients with perfo-rated appendicitis, diagnostic sensitivity increased significantlywith symptom duration with ultrasound but not CT.

For children with suspected uncomplicated (that is, nonper-forated) appendicitis and <36 hours of pain, the authors recom-mend not relying on a negative ultrasound. Although CT is asecond study option, the authors advocate for reevaluation withultrasound after a period of observation to avoid unnecessaryradiation exposure. Alternatively, they suggest postponing theinitial ultrasound until sufficient time (>24 hours) has passedto increase its sensitivity.

Panic Disorder and Vulnerability to LaterAtrial Fibrillation Key point: Panic disorder is NOT just “hysteria” and should berespected as a risk factor for other serious conditions. Citation: Cheng Y-F, Leu H-B, Su C-C, Huang C-C, et al. Asso-ciation between panic disorder and risk of atrial fibrillation:A nationwide study. Psychosom Med. October 29, 2012. Doi:10.1097/PSY.0b013e18273393a.

Although panic disorder has been associated with increased risksfor myocardial infarction, whether panic disorder might alsospecifically increase the risk for atrial fibrillation (AF) has not pre-viously been studied. Using a Taiwanese national insurancedatabase, investigators compared 3888 patients receiving base-line diagnoses of panic disorder with 38,880 control individu-als, balanced according to known risk factors (such as age, sex,and histories of diabetes, hypertension, and hyperlipidemia).Participants with preexisting arrhythmia were excluded.

Relative to controls, those with initial panic disorder had el-evated baseline rates of chronic obstructive pulmonary disease(COPD) and depression. Participants were tracked for up to 7years for the subsequent development of AF (diagnosed by car-diologists). At follow-up, 406 participants (0.94% of entire pop-ulation) had developed AF (panic disorder group, 1.2%; non-panic group, 0.9%). After adjustment for risk factors andcomorbidities, initial panic disorder was independently asso-ciated with increased risk for developing new AF (hazard ratio,1.73), as were age, male sex, hypertension, and histories of coro-nary disease history, congestive heart failure, and valvularheart disease (but not COPD or depression).

C O D I N G Q & A

Q. Can a patient be billed for an E/M code and an ultra-sound procedure such as 93970, “Duplex scan of ex-

tremity veins including responses to compression and oth-er maneuvers; complete bilateral study” during the same vis-it when both the scan and the E/M visit were performed bythe same provider?

A. If during an office visit it is determined that the ultrasoundprocedure needs to be performed on the same day as the

visit, you may code an E/M in addition to the procedure. You wouldappend modifier -25 to the E/M code. 

CPT guidelines do state, however, that if only a hand-held orother Doppler device is used and a hard copy of the results is notproduced, then the CPT code for the noninvasive vascular pro-cedure may not be used, because the procedure is deemed to beincluded in the E/M service. 

However, during an outpatient visit, if the provider determinesthat the patient needs the ultrasound procedure performed butthe patient is scheduled for the procedure on a different day, youwould not bill an additional office visit on the day the patient re-turns for the procedure.

Be sure to check Local Coverage Determination (LDC) rules withstate licensing authorities, and with each payor, because someentities have limitations on who can perform or bill for noninva-sive vascular diagnostic studies. For example, the provider or set-ting for these procedures may be limited to:

� physicians who are competent in diagnostic vascularstudies;

� physicians who are under general supervision by physi-cians who are credentialed in vascular technology;

� technicians who are certified in vascular technology; or� facilities with a laboratory accredited in vascular tech-

nology. ■

Q. If during a well child exam a pediatrician discoveredthe patient had eczema and prescribed treatment, is

the treatment of the eczema significant enough to warrantusing a modifier -25?

A.Modifier -25, “Significant, separately identifiable evalua-tion and management service by the same physician or

other qualified health care professional on the same day of theprocedure or other service” is reserved for E/M codes (i.e., in ur-gent care, CPT codes 99201-99215) so you would not append itto the well child/preventive service code.

If billing an E/M code, you would not use modifier -25 unlessanother appropriate billable “procedure or service,” such as a woundrepair or a foreign body removal, was performed. ■

Q. As an employee of a family practice/pediatrics cen-ter, I have been asked to add S9088 when a patient

comes in on the same day without a scheduled appointment.We are not licensed as an urgent care clinic, but we do seepatients who come in without an appointment. Our hoursof operation are 8:30 a.m. to 5:00 p.m. Monday through Fri-day only. Can we use urgent care codes for the patients wetreat who do not have an appointment?

A. If you are referring to HCPCS code S9088, “Services pro-vided in an urgent care center,” you should not use this

code in a physician office setting because it is specifically reservedfor use by urgent care centers.

However, there are a few codes that you might be able to con-sider using in an office situation. CPT code 99058, “Service(s) pro-vided on an emergency basis in the office, which disrupts otherscheduled office services, in addition to basic service,” could beused for someone who did not have a scheduled appointmentbut was in need of an emergency service and had to be taken backto an exam or procedure room immediately for treatment.

In that instance, you would bill CPT code 99058 in additionto the appropriate E/M code as well as codes for any other pro-cedures performed. However, for urgent care centers, CPT As-sistant has made a controversial statement that this code isnot appropriate for clinics that typically see patients on a walk-in basis. ■
