Introduction

Evidence demonstrates that pharmacists’ care

enhances patient health.1 Pharmacy practiceworldwide is evolving from dispensing and educat-ing patients to providing patient-centered care

where pharmacists assess the appropriateness ofmedication therapy, ensure patients have an un-derstanding of their drug therapy, encourage ad-

herence to medications, and monitor patientoutcomes.2 In the pharmacy literature, patient–pharmacist communication has been conceptual-ized as a transmission action or a transaction.3

Transmission is a one-way process from sender toreceiver. Biomedical communication usually fol-lows a transmission model where the pharmacist

concentrates mainly on providing medication-related information. The transaction model isa two-way process, where shared meaning is nego-

tiated between two participants such as in patient-centered communication where the pharmacistidentifies and responds to patients’ ideas and emo-tions regarding their illness.3

The main difference between the patient-centered and biomedical models is the level ofpatient engagement.4 The biomedical model en-

hances the control and status of the pharmacist,whereas the patient-centered model enhances thecontrol and status of the patient. During biomed-

ical communication, the pharmacist focuses onthe treatment of the disease with little attentiongiven to the role of psychological or social influ-

ence.5 In the patient-centered model, the patientcollaborates with the pharmacist to: 1) identifytreatment goals; 2) choose from regimen options;3) monitor symptoms and evaluate regimens;

and 4) revise regimens if problems occur.6 In thepatient-centered model, the pharmacist works di-rectly with a patient and in conjunction with other

practitioners to take responsibility for achievingthe optimized outcomes of drug therapy.7 It in-volves the development of an individualized care

plan to achieve the intended goals of therapywith appropriate follow-up to determine patientoutcomes.8 Several studies have found an associa-

tion between patient-centered communication and

increased patient satisfaction, treatment adher-ence, improved medical outcomes, and decreased

number of malpractice claims.9–14

To transition to patient-centered care, phar-macists require strong communication skills.15

Two recent review articles have examined pa-tient–pharmacist communications. Shah andChewning found that research has focused on

one-way communication from the pharmacist tothe patient.3 Puspitasari et al took an interna-tional perspective and found pharmacist counsel-ing rates vary worldwide from 8% to 100%,

with more counseling for new rather than refillprescriptions.16 Pharmacists more routinely pro-vided information on directions for use, dose,

medication name, and indications than on side ef-fects, adverse events, and storage.16 Both studiesreported diverse research methods with a focus

on self-report surveys, non-participant observa-tion, interviews, and shopper studies that werecross-sectional in nature. These studies frequentlyfocused on the pharmacist and did not capture ac-

tual patient–pharmacist interactions. Shah andChewing reported only one audio analysis thatwas conducted by Blom et al17 Puspitasari et al

mentioned the same research in addition to a studyby Evans and John18 and Livingstone.19

An analysis of patient–pharmacist recordings

would allow for detailed study of patient-centeredcare. Audio or video recordings of patient–pharmacist interactions can capture the detail

of what happens in real interactions betweenpatients and pharmacists, how these interactionstranspire, and provide evidence as to why com-munication occurs.20 Standardized questionnaires

and interviews test hypotheses by measuringpre-specified constructs. Respondents constructa belief or attitude that may vary in differing situ-

ations.21 Qualitative interviews allow for greaterexploration, but as with structured surveys, relyon recall of events. Observational research with

simulated patients (e.g., pseudo-patients, secretshoppers) or pharmacy observations have an im-portant role in determining “what” happens in

a patient–pharmacist interaction whether it is the

implementation of a new technique or content ofpharmacists’ advice.22 Mesquitta found that phar-macy research using simulated patients did notdefine and therefore could not measure patient–

pharmacist communication skills or competencies.22

Patient–pharmacist audio recordings allow forunique study of how or why patient–pharmacist

interactions take place; this research is notpossible with other methods. “Examining patient–pharmacist communication as an interpersonal

dyadic interaction may help us understand col-laborative problem-solving activities, and interper-sonal relationship development within the context

of mutual trust, rapport, and familiarity betweenthe participants.”3

There is an emerging body of research thatused recordings of patient–pharmacist interac-

tions as a data collection method and wanted todetermine how this research technique has beenemployed in pharmacy practice research. The

analysis of recordings uses a variety of methodsfrom quantitative coding of the interaction,qualitative inductive methods, and discourse

analysis.20 Discourse analysis is a methodologicalapproach that is often used in the study ofcommunication in health care consultations. It

involves the study of spoken and written lan-guage and how language use reflects social orderand individuals’ interactions within society.23

This technique focuses on turn-taking, repair of

conversation breakdown, topic managementand non-verbal behaviors. The analysis approachand resulting findings may characterize patient–

pharmacist communication as biomedical orpatient-centered. The current study used an ad-aptation of the meta-narrative review, which is

a coherent body of work that shares a commonset of concept, theories, methods and instrument,to present our results.24 Meta-narrative reviewsare best suited to study topic areas where existing

studies have been conceptualized differently and/or conducted by many different researchers. Theresearch using recordings from pharmacy prac-

tice arises from quantitative, qualitative and dis-course analysis traditions which influences howresearch has been conceptualized and designed,

and therefore also the key findings that result.This review aims to characterize the 1) focus ofresearch questions, 2) study design, 3) data anal-

ysis methods, 4) main findings, and 5) presence ofpatient-centered vs. biomedical models of inter-action in recorded patient–pharmacist interac-tions with attention to the influence of the

research tradition.

Methods

Data sources

A literature search was performed by a medicallibrarian to identify studies published in English.

No publication date limits were implemented.Searches were conducted in the following data-bases: Ovid Medline, Ovid Embase, InternationalPharmaceutical Abstracts (IPA), Web of Science,

and Academic Search Complete. Two differentapproaches were used to identify relevant studies:search terms related to patient–pharmacist en-

counters (such as “patient counseling” and “pa-tient interaction”) were combined with eithersearch terms related to the medium of collection

(i.e., audio or video recordings), or to searchterms about the method of data analysis (e.g.,“discourse analysis”, “conversation analysis”,“narrative analysis”, “content analysis,” etc.).

Keywords about the methods of data analysiswere added to include several articles that werefound in cited references and not on the first

electronic search. In addition, reference lists ofincluded articles where reviewed to identify addi-tional relevant studies. The search results are

shown in (Fig. 1).

Study selection

Two authors identified citations by screeningtitles and abstracts for potential relevance. Thefull text article for each potentially relevant

citation was obtained for further evaluation.Studies were eligible for inclusion if they examinedpatient–pharmacist interactions using audio or

video recordings, were published in English asa peer-reviewed full-text article, and used realpatients or simulated patients. Papers were ex-cluded that used pharmacy students and interns or

used audio or video materials solely for teachingpurposes. The full text articles were examined todetermine eligibility for inclusion; any discrep-

ancies regarding inclusion were resolved by dis-cussion. One author extracted details on researchquestion, method, analysis, and main findings and

a second author verified extraction.

Defining patient-centered vs. biomedical model

Studies were defined as patient-centered if thestudy specifically stated it measured patient-centeredness or if the pharmacists applied several

elements of patient-centeredness during their con-sultations with patients such as: incorporating thepatient perspective into treatment discussion,

active listening, asking open-ended questions, andverifying patient understanding.25–28 Articles rep-resenting the biomedical communication modellacked patient-centered elements or exhibited

pharmacists dominating the interactions with pa-tients playing a passive role. These studies oftenconcentrated on the content of counseling.

Results

The search identified 586 studies. Of these

articles, 162 were duplicates and additional 383articles were excluded after independent assess-ment by the two authors. Authors agreed on theallocation of all articles therefore 41 articles met

the inclusion criteria. These represent 32 uniquecollections of recordings. One study was publishedin the 1980s, 10 in the 1990s, 22 after 2000, and

eight after 2010. The research was predominatelypublished in the quantitative research paradigm(20 studies; Table 1) followed by qualitative re-

search (5 studies; Table 2) and discourse analysis(13 studies; Table 3). The remaining three studies(Table 4) used expert groups to develop criteria

for the quality of patient–pharmacist interactions(2 studies) or a mixed method approach (1 study).The following sections discuss the research ques-tions, study designs, data analysis, and findings

as conceptualized in each research tradition.

Research questions

The research questions were driven by the

research method. The quantitative research ques-tions (Table 1) can be categorized as 10 studies fo-cusing on the content of the interaction,17,18,29–35

4 on evaluating the quality of interactions witha validated tool36 or to validate a tool,34,37,38 twoon patient recall,39,40 two that test a hypothesis,41,42

one to evaluate an intervention,43 and one on vali-

dating the quality of stimulated patient recall.44

The five qualitative studies explored pharmacistsin new roles,25,45,46 maintenance of professional ex-

pertise47 and communication breakdown.48 The re-search in discourse analysis asks oneof twoprimaryquestions regarding either the structure of patient–

pharmacist communication or the exploration ofphenomena including acceptance of advice,49

conflict talk,50 patient expertise,51 compliance

paradigm,53 effective strategies for verifying under-standing,26 and the role of assistants.23 In all para-digms, six studies used theory explicitly to guide theexploration of patient–pharmacist communica-

tion.20,46–50 The quantitative studies focused onthe “what”, the qualitative studies explored newor specific roles, and the conversational analysis

focused on the “how” patients and pharmacistsinteract.

Design and methods

Researchers used video recordings in ninestudies31,32,37,38,41,48,50,54,55 and audio recordingsin the remaining 32 studies to collect patient–

pharmacist interactions. In the qualitative48 anddiscourse analysis research,26–28,55 videos weretranscribed for analysis; thus video did not appearto add to the analysis. In the quantitative studies,

three studies coded elements only available invideo,37,38,41 while two examined content.31,32

Simulated patients in university practice laborato-

ries or community pharmacies were employed infour articles. In seven articles audio recordingswere collected in hospitals,45,48,56,57 five in pa-

tients’ homes,36,45,49,50,53 and the remaining re-search studies were conducted in communitypharmacies. No clear pattern emerged between

research paradigm and research location. The dis-course research was most likely two have multipleanalyses conducted on one dataset (Table 3). Onedataset was used in both a quantitative31 and dis-

course analysis study.55 Ten studies combined twoor three data collections methods such as: ques-tionnaires, non-participant observations and in-

terviews. Multiple methods of data collectionwere most prevalent in the qualitative para-digm.25,46–48 We did not identify any longitudinal

studies. The single intervention study found thathealth belief model and use of open-ended ques-tions improved the content and quality of patient

interactions.43 The bulk of this research has beenconducted in the United Kingdom followed bythe United States of America.

Consent procedures were outlined in the ma-

jority of studies, but 10 out of 41 studies (i.e., 7datasets) did not report consent procedures orapproval from an ethics review commit-

tee.25,29,32,37,45,51,56–58 One study reported ethicalapproval, but not consent procedures.47 Nine ofthe studies posted a sign to inform the patients

of the recording, assuring them of anonymityand confidentiality with five studies using this asthe sole form of consent.29,34,35,40,54 Oral consent

was solely obtained in three studies,30,42,46 andoral consent was combined with a sign in onestudy.59 The remaining studies used a written con-sent in combination with oral consent and signs.

Data analysis

Quantitative methods dominated (Table 1)

followed by discourse analysis (Table 3). Only 3studies analyzed their data by other methods.54,60,61

All studies in the discourse analysis and qualitativeparadigmsanalyzed transcriptswhereas 10quantita-

tive studies (Table 1) conducted their analysis on theaudio itself by characterizing the content32,40 or byemploying a scoring tool.17,34,37,38,41–44 Studies using

a quantitative paradigm quantified the frequency ofencounter reason, content of oral drug information,oral drug information received, and pharmacists’

and patients’ behavior at the counter. Furthermore,the number, type, and content of questions asked bypharmacists were reported. Validated tools were

used toanalyze data in several studies,30,31,36,62 whilefive authors developed their own coding tools. Allstudies characterized elements of pharmacist com-munication, several also explicitly analyzed patients’

contribution to the interaction30,45–47,49,51,53 and twostudies examined patient recall.39,40

Main findings

Main findings were driven by the questionsasked in each research paradigm. The quantitativestudies characterized what happened between

patients and pharmacists. Pharmacists’ consulta-tion focuses mainly on medications instruc-tion.17,19,31,33,40 Several studies quantified the

number and type of questions asked by pharma-cists and found that pharmacists asked moreclosed questions than open ones.18,30,31 A compar-

ison showed that pharmacists provided more in-formation and advice than technicians.17,29 Inaddition, the percentage of what the patients re-

called after counseling was calculated and foundto be approximately a quarter of what the phar-macists said in one study39 and half in the secondstudy.40 Patients mainly recalled instructions and

repeated information.39,40 Quantitative methodol-ogy was used to develop and test evaluation toolsfor pharmacists consultations with patients37,38

and to measure patient-centeredness.36 Betterpharmacist communication quality and greaterpatient satisfaction resulted when patient-

centered skills were applied during counseling.41,42

The qualitative paradigm provided rich descrip-tions of novel pharmacists’ practice or areas.

Specialized pharmacists’ communication includedpatient engagement and acceptance.25,45,46 Pharma-cists’ expertise was important and not diminished byengaging patients in decision-making.47 Breakdown

in patient–pharmacist communication was due tothe pharmacist or pharmacy environment.48

Discourse analysis reported how pharmacists

communicate with patients. The structure of theinteraction was primarily focused on the pharma-cist providing medication information. Patients’

expertise was disregarded by pharmacists,49 re-duced pharmacists’ expected dominance,51 andled to patients disregarding advice49 or inquires

that threatened their competence.53 Pilnick foundthat conflict was resolved with referrals to physi-cians. Watermeyer and Penn identified four waysto verify patient understanding (Table 3).26

Ylanne and John described three ways pharmacistassistants interact with patients (Table 3).23

Several studies investigated the characteristics

of pharmacists and/or patients that may influencethe nature or extent of communication. Pilnickfound that patient expertise reduces the expected

interactional dominance of the pharmacist.51 Thequality of patient–pharmacist communication wasaffected by the environment and positively im-

proved if pharmacists applied patient-centeredskills18,41,42,48,54 such as: patient involvement, lis-tening, and integrating patients perception.

Presence of patient-centered vs. biomedicalcommunication

The research paradigm with its resulting ques-tion and measurement model had an impact on

whether or not patient-centered or biomedicalcommunication was characterized. Eight studiesfound evidence of a patient-centered model in

patient–pharmacist interaction, whereas 23patient–pharmacist interactions exhibited a bio-medical focus. Patient-centered communication

primarily took place in specialty clinics and bypharmacists with additional training or a specificclinical focus.25–28,36,45,46 The community-basedpharmacy study that identified patient-centered

behaviors used pharmacists to characterize effec-tive communication performances.54

Quantitative studies focused on the clinical

content resulting in a focus on biomedical com-munication. If patient-centered communicationwas present it was not quantified with the excep-

tion of Greenwood, Howe, and Holland36 whoused validated scales with the specific intent ofcharacterizing patient-centered communication.

Page 16: A meta-narrative review of recorded patient–pharmacist interactions: Exploring biomedical or patient-centered communication?

16 Murad et al. / Research in Social and Administrative Pharmacy j (2013) 1–20

Qualitative research, which studied specializedpharmacists, found patient-centered communica-tion.25,45,46 Other topic questions on communica-

tion breakdown48 and pharmacists expertise47 ledto a focus on biomedical communication. Dis-course analysis described eight studies with abiomedical and three with patient-centered

communication style. The patient-centered com-munication style was found in a specialty clinicand these studies described how pharmacists

counsel patients about their antiretroviral medi-cations.26–28

Discussion

Forty-one studies were identified that analyzedvideo and audio recordings of patient–pharmacistinteractions. A greater number of articles were

found than were identified in prior reviews4,16 be-cause additional keywords were included such asdiscourse, conversation, narrative, and content

analysis and the search was conducted in both so-ciological and health sciences literature databases.Research on recordings of patient–pharmacist in-

teractions reside within multiple research fieldswith distinct traditions within pharmacy as wellas sociology and linguistics.

The majority of studies were published in thelast ten years, suggesting a growing interest inpatient–pharmacist communication. The vast ma-jority of the research was conducted using audio

recordings in community pharmacies and wasdescriptive in nature. Consent procedure wasdescribed in the majority of studies with a majority

using written consent. The five studies that useda pharmacy sign as the sole means to alert patientsoccurred in 2000 and earlier. Few studies used

simulated patients during data collection. Onlythree of the 10 studies that employed videosanalysed non-verbal behavior. Transcripts of

recorded patient–pharmacist interactions wereused in the analysis process in both qualitativeand discourse methodologies. Half of the quanti-tative studies analyzed the transcripts and the

remaining quantified the content directly from therecording with scoring tools. In most of thestudies, results were analyzed quantitatively while

discourse analysis and qualitative methods wereemployed in the remaining articles.

Much of the literature covered in this review

suggests, (1) that the evidence of biomedical vs.patient-centered models in the studies’ findingsdepends on the research questions and analysis

methods; (2) the majority of studies using a bio-medical approach looked at the content of patientcounseling and quantified their findings; (3) eight

studies found pharmacists applied several ele-ments of patient-centeredness during theirconsultations with patients. These results alsoresonate with the views of several papers that

recognize the need for closer attention to patient-centered care in current-day pharmacy.15,63–65

One of the included studies showed that patients

reported a high level of satisfaction when thepharmacists adapted their own model of concor-dance.46 However, the results also conflict with

the previous finding in the medical literature thatwhile the vast majority of patients prefer thepatient-centered approach, a significant propor-tion still prefers a biomedical communication

model.66 No single demographic or clinical char-acteristic reliably predicts patients’ communica-tion style preferences,66,67 and prior research

shows that pharmacists are often unaware ofwhat patients expect and evaluate as being impor-tant when they visit the pharmacy.68,69 Krass et al

have shown that pharmacists’ use of one well-intended question may trigger different patient re-sponses.70 Patients’ variation in responses may be

due to of their personal interpretation of the sug-gested relationship70 or health beliefs.71

Furthermore, the findings of this review showthat patient–pharmacist interactions are not con-

sistently analyzed as a dyad. Since patients andpharmacists individually determine the quality oftheir interactions, it is important to incorporate

both parties’ prior experiences.3 A very limitednumber of studies in this review described howthe quality of patient–pharmacist interactions is

positively affected with pharmacists’ centeredcare skills. This review described the studies thatanalyze recorded patent–pharmacist interactionand it shows that audio and video recording meth-

odology allows researchers to draw conclusionsabout the real-time effects of interaction betweenpatients and pharmacists.20 However, recordings

can create an artificial environment, as pharmacistand patient are aware that they are being recordeddue to the consent procedures. This causes a be-

havioral change, the so-called ‘Hawthorne effect’.Some studies recorded patient–pharmacist inter-actions in the absence of a researcher in order to

decrease the ‘Hawthorne effect’.25,29,53,60

Few studies used simulated patients in theirresearch.We identified only three data sets and fourstudies that used simulated patients. Two used real

pharmacists in a lab where the pharmacist was

Page 17: A meta-narrative review of recorded patient–pharmacist interactions: Exploring biomedical or patient-centered communication?

17Murad et al. / Research in Social and Administrative Pharmacy j (2013) 1–20

aware of the interaction31,55 and twowere recordedin the community pharmacy setting where pharma-cists were unaware of simulated patients but wereinformed that a visit would come within a desig-

nated timeframe.43,44 Using simulated patientscan enhance the reliability and validity of thedata22 and allow for comparisons between pharma-

cist responses to the same patient query. Simulatedpatients can judge the performance of the pharma-cist in a reliable way. Finally, the simulated patient

has increased face validity if the pharmacist doesnot know or suspect the presence of a simulatedpatient.

Few studies used more than one method ofdata collection but two studies used both quanti-tative and qualitative analysis methods. Mixedmethods data collection and analysis may provide

more thorough and insightful findings.72 Severalstudies employed qualitative methods of data col-lection (e.g., interviews) and also presented quali-

tative data (such as verbal data rather thatnumerical data). Using qualitative methods inpharmacy communication research is important

for understanding social situations from the view-point of all parties involved. Non-specific the-matic analysis was the predominant analysis

approach. One study used an interpretive ap-proach whereby the researchers developed a senseof the whole dataset before generating impres-sions of the individual parts.

In several studies data was analyzed usingdiscourse analysis. In these studies, this methodis described as qualitative. However, discourse

analysis can be both a quantitative and qualitativemethod.73 Discourse analysis resulted in rich de-scriptions of patient–pharmacist interactions and

contributed to new understandings of how pa-tients and pharmacists manage conflict, power,and expertise when communicating about medica-tion. The questions and thick analysis resulting

from discourse analysis may not directly lendthemselves to practice enhancements, but mayguide the understanding of existing communica-

tion practices.

Strengths and limitations

Possible limitations include not searching fordissertations or unpublished work and the re-striction to only English language articles. The

data is widely varied and not sufficiently mature toallow for definite conclusions. There are severalpoints of strength in our review. It is based on

a literature search conducted in several databasesin both the health and social sciences. A detaileddescription of research questions, methods, anal-yses and findings is presented. This is the first

review to discuss this number of studies thatcollected and analyzed audio and video recordingsof patient–pharmacist interactions.

Future research directions

The diversity of this body of research could

lead in many directions. First, researchers shouldcarefully match the research objective, method ofrecording, and research methodology. There are

few pharmacy specific validated coding tools thatwould help quantify pharmacists’ and patients’communication. Simulated recall of information

presented in patient–pharmacist interactions mayprovide rigorous evaluation of patients and phar-macists’ perceptions of biomedical vs. patient-

centered communication. Future research usingdiscourse analysis may consider investigating thestructure of exchange between the patient–phar-macist dyad as well as characterizing structural

differences in communication in differing contexts(e.g., new vs. refill prescriptions). It would behelpful for the profession, patients, and re-

searchers to understand how pharmacists andpatients organized the interviews and how thismay have influenced patients’ medication taking

behaviors. It is not known how pharmacistsdetermine patients’ communication preferencesand subsequently adjusts their communication

styles according to patient preference. As thestructure of patient–pharmacist interactions isuncovered, it will be important to link pharma-cists’ communication to patient health outcomes.

Conclusion

There is a developing body of research usingaudio and video recordings to describe the contentof pharmacists’ communication in addition toexploring the quality of the interactions, valida-

tion of coding tools, the impact of an intervention,and an enhanced understanding of the patient–pharmacist power asymmetry. Evidence for bio-

medical vs. patient-centered models in the studies’findings depends on the nature of the researchquestions and analysis methods. The quantitative

studies focused on the “what”, the qualitativestudies explored new or specific roles, and thediscourse analysis focused on the “how” patients

Page 18: A meta-narrative review of recorded patient–pharmacist interactions: Exploring biomedical or patient-centered communication?

18 Murad et al. / Research in Social and Administrative Pharmacy j (2013) 1–20

and pharmacists interact. Future research shouldfocus on how pharmacists partner with patients toapply patient-centered care in differing contexts

and explore the links between communication andpatient health outcomes.
