Early U.S. Formularies• Lititz Pharmacopoeia published in 1778 for use by
the Continental forces
• Coste’s Compendium Pharmaceuticum of 1780 used by French forces during the American Revolution
• United States Pharmacopeia Convention meets in Old Senate Chamber Jan 1, 1820– Selects drugs for the Pharmacopeia of the United States – Oldest non-profit organization in the U.S.
Drug Formulary:
“A continually updated list of medications and related information, representing the clinical judgment of physicians, pharmacists and other experts in the diagnosis and/or treatment of disease and promotion of health.”
Drug Formulary System:•Ongoing process
•Collaboration of physicians, pharmacists, and other health care professionals
•Establishes policies on the use of drug products and therapies most medically appropriate and cost-effective to best serve the health interests of a given patient population.

Leading Challenges to CCH/UIC Formulary Committees
• MD’s circumventing formulary and formulary application process for new drugs by using non-formulary ordering route
• Inadequacies of the studies on which to base decisions• Lack of dedicated time of members to fully and critically
digest literature and deliberate at the meetings • Wrestling with extremely costly ($10k/yr) new agents that
appear to be effective, but pose major stain on institutions’ drug budget resources
• Pharmaceutical industry influences and practices (including lobbying members, pricing schemes)
“CDC Drugs of Choice
Methodology
This report was produced through a multistage process. Beginning in 2004, CDC personnel and professionals knowledgeable in the field of STDs systematically reviewed evidence, including published abstracts and peer-reviewed journal articles concerning each of the major STDs, focusing on information that had become available since publication of the Sexually Transmitted Diseases Treatment Guidelines, 2002 (1). Background papers were written and tables of evidence were constructed summarizing the type of study (e.g., randomized controlled trial or case series), study population and setting, treatments or other interventions, outcome measures assessed, reported findings, and weaknesses and biases in study design and analysis. A draft document was developed on the basis of the reviews.
WHO Essential Drugs List
• In 1977, WHO published the first Model List of Essential Medicines containing 208 individual drugs which together could provide safe, effective treatment for the majority of communicable and non-communicable diseases
• With these models, and inspired by WHO’s HFA program, in 1982 Bangladesh implemented its National Drug Policy (NDP). An expert committee assembled a list of recommendations based on WHO’s EDC, and the NDP aimed to ensure that procurement, local production, quality control, distribution, and use of pharmaceuticals came under the control of a single government body. This was to be a major part of national health policy.
Bangladesh Essential Drugs Program-1982
• No sooner had a form of the NDP been implemented than foreign-owned drug companies mobilized a campaign of misinformation, threats, and intimidation. For example, on June 1, 1982, the Bangladesh Times publicized the NDP. That same morning, the U.S. ambassador made an unscheduled call on the government to deliver the message that the policy was not acceptable to the U.S. government. Although the U.S. government had no overt interest in the NDP, drug companies, which had made considerable donations to the election campaigns of members of the U.S. government, assuredly did. They mobilized the influence their money had purchased against the NDP, which is why a superpower became involved in the internal health affairs of a small country on the other side of the globe

Leveraging Formularies for Improved Prescribing
1. Venue for critical review of new drug claims
2. Evaluation of comparative efficacy3. Less bias and conflict in decision-making4. Cumulative expertise in reviewing new
drugs5. Experience with pitfalls and biases6. Identify and weigh potentials for
overuse/misuse7. Weighing of cost benefit (for individual
drug/indication)8. Weigh institutional resource allocation
(this drug vs. alternatives)9. Raise/highlight safety concerns10. Dissemination vehicles and tools
(guidance and warnings)
1. More rational prescribing2. Enhanced appropriateness

Formulary Myths
1. Causal empiricism
2. FDA approval implies everyday use for all
3. Interferes with clinical freedom
4. Every patient is unique
5. Specialist knows best
6. Education requires experience with multiple drugs
7. Widespread use = drug of choice
8. Newer is better/safer
9. Sicker patients need more drugs
10.Formulary sacrifices patient care to cost
11.Redundant with drug utilization review

ISMP 2004 Survey Results Formulary Myths Still True !!
• 70% reported causal empiricism comments impacting formulary decisions
• 73% reported specialist knows best comments impacting formulary decisions
• 49% reported never hearing FDA use implies everyday use for all comments in formulary deliberations

How I’ve FLIPPED –Bill GTry to treat any complaint or disease
non-pharmacologically unless truly. Necessary as drugs are poisons and our role is to first do no harm.
New drugs are inherently more risky and likely dangerous than old drugs And should be used sparingly only when truly necessary.
One paper does not always tell the whole story, a thorough review of the Literature is important if you plan on changing your treatment or begin to use a medication.
How I’ve FLIPPED –Gordy S
Realization that no conflict-of-interest voting policy, even on my own Committee
Different conceptualizations and processes on different formulary committees related to “P&T” vs. “formulary” functions
-Medicaid- completely separate
Outpatient dominates CCH, inpatient rules at UIC w/ resulting entirely different framework for discussion
Selected Quotes from Formulary Focus Groups:
What do Clinicians think of their Formulary and the Formulary Process?
Selected quotes UIC• What works on our committee is that we make decisions based
on literature.• [I am] generally satisfied with the Drug Information Center.
Other institutions don’t have as much detail. The DIC does the best they can with the information that is available. For new drugs there isn’t really that much to work with anyway.
• Non-formulary drug requests and discouraging people to avoid non-formulary are continuously a problem. People don’t understand why they shouldn’t use non-formulary. Improvement is needed to understand what the formulary is there for.
• [The committee’s been] almost the same in format for 22 years. It’s tried and true and very standard. It has a survival or Darwinian quality.
Selected quotes Cook County• [One strength of the committee is] participation of clinical
pharmacists to give support and do good drug evaluations.
• Many departments are represented and this is educational.
• The studies available for drugs/new drugs are of poor quality. For example, drugs for senile dementia or diabetic neuropathy.
• Although the committee communicates what is happening in hospital, there are still problems with dissemination. Dissemination is not always successful.
• Making people “jump through hoops” is bad for patients because people should have their medicine.
• We often say we will audit drugs put on the formulary but this does not happen. Doctors feel more comfortable with this kind of evaluation. We put a lot of drugs on which are expensive with marginal benefit. Data does not come back to the committee about usage or patient outcome.
• We are trying to treat everything possible when we cannot afford to. We make some decisions about what to treat and what not to treat, for example we stopped doing bone marrow transplants but we do give anti-rheumatologics
• If you have patient experience you typically give evidence that is more anecdotal, but it does not go unchallenged. Sometimes the committee invites specialists to talk to the group but they are less open now. Some only show up when there is a controversial drug.
• It is not the formulary committee’s role to be a pharmacy budget organization but we still have to make these kinds of decisions. This causes schizophrenic decisions. A lot is lacking in decision-making.
• County has an excellent cardiovascular formulary which has saved millions of dollars. Not running for expensive cures. This restrictiveness is one reason we miss some of the major adverse drug reactions. By the time treatments become cost-effective the ADR’s are discovered.
