A qualitative study on community pharmacists' decision-making process when making a diagnosis

Community pharmacists' decision-making patterns in clinical prescription checking: A simulation-based study

Background

Community pharmacists (CPs) make a significant number of decisions on the clinical appropriateness of prescriptions daily to ensure safe and effective use of medications, in a process known as "clinical checking". The process is complex and is affected by multiple factors in practice. This study aimed to investigate the cognitive processes involved in clinical prescription checking by CPs.

Method

This qualitative study employed a purposive sampling technique to recruit a diverse sample from the population of CPs in England. Engaging in Zoom interviews, participants clinically checked three simulated prescriptions, providing concurrent verbal accounts of their thoughts. The participants' commentaries during the task were audio-recorded, transcribed verbatim, and underwent deductive thematic analysis based on Klein's recognition-primed decision-making (RPD) model.

Results

Twelve CPs from diverse backgrounds and varied working conditions were recruited and completed the online checking task. Making decisions on the clinical appropriateness of prescriptions appeared to be a multi-staged procedure whereby several levels of concerns exist, and pharmacists vary in their ability to recognise and resolve those concerns. CPs behaved in a manner similar to that described by the RPD model; they mostly engaged in pattern-recognition during clinical checking, but adopted a more analytical approach when they recognised an atypical situation. Participants showed more consistency when processing cues and expectancies; however, their subsequent actions exhibited substantial variability, coupled with a degree of hesitancy.

Conclusion

Clinical checking of prescriptions is a multifaceted process in which pharmacists employ a blend of pattern recognition and analytical thinking when making decisions. The process differs notably among pharmacists, underscoring the need to understand the factors driving these variations and any hesitancy in decision- making, as well as their potential impact on patient safety.

Pharmacists' clinical decision making when responding to a self-medication request for a cough in a developing country

BACKGROUND

Some studies have reported that community pharmacies in developing countries, including Indonesia, provided sub-optimal advice when handling patient's self-medication request for cough. The reasons behind such advice, therefore, need to be investigated.

OBJECTIVES

To describe Indonesian pharmacists' clinical decision making when handling self-medication cases for a cough.

METHODS

An open-ended questionnaire consisting of two cough clinical vignettes (case 1: cough due to asthma worsening and case 2: cough as a symptom of common cold) were developed. Pharmacists were interviewed to provide recommendations and reasons for their recommendations for these scenarios. Content analysis was used to analyse participants' statements for the two scenarios. The number of participants who provided appropriate recommendations and reasons were then counted.

RESULTS

A total of 245 community pharmacists participated in the study. In the case of cough due to asthma worsening, recommending a product because the product was indicated to help with the symptoms was the most common recommendation and stated reason (40%). Appropriate recommendation (direct medical referral) with appropriate reasoning (indicating warning symptoms and/or making a symptom diagnosis) was provided by 25% participants. In the case of cough as a symptom of common cold, recommending products to help with the symptoms was also the most common recommendation and stated reason (53%). Appropriate recommendations (recommending product) with appropriate reasoning (providing product to treat the symptoms and/or indicating no warning symptoms and/or making a symptom diagnosis) was provided by 81% participants.

CONCLUSION

The ability of Indonesian community pharmacists to provide appropriate recommendations for cough self-medication requests is dependent on whether triage is required. The inability of most community pharmacists to differentiate between major and minor conditions may lead to serious health implications for patients and therefore educational interventions should be undertaken to improve community pharmacists' differential diagnostic skills for triage.

Leverage points for establishing clinical decision-maker as a vital component of pharmacists' professional identity

This commentary explores how a change in the professional identity of pharmacists from medicines supplier to clinical decision-maker might take place. Three leverage points are identified that support this change. The first leverage point involves workplace culture. Pharmacists require workplaces that support them to assume direct responsibility for drug therapy decisions that may not have traditionally been part of pharmacy practice. The second leverage point involves terminology. Pharmacists need to be able to name and describe the process they use when making decisions about drug therapy. The third leverage point encompasses pharmacy education. Future pharmacists require a foundation that enables them to mobilize their knowledge and skills about drug therapy to act as clinical decision-makers with patients that require complex care. By acting on multiple leverage points, advocates for change in the pharmacy profession can assist pharmacists to establish themselves as decision-makers about drug therapy, shift their professional identity, and reformulate their view of the profession.

Managing common ambulatory conditions: Exploring clinical decision making performance between pharmacists and family physicians

Background

Prescribing is part of the expanded scope of practice for pharmacists in Alberta, Canada. Given these responsibilities, clinical decision making (the outcome from the diagnostic and therapeutic decision making process) is an essential skill for pharmacists. The current study compared diagnostic and therapeutic decision-making between Additional Prescribing Authority (APA) pharmacists and family physicians using a set of common ambulatory clinical cases that both practitioners could encounter in the community as part of their daily practice.

Objectives

To explore clinical decision making performance and behaviors between APA pharmacists and family physicians during the assessment and prescribing of common ambulatory conditions.

Methods

Eight written ambulatory clinical cases were developed by a panel of experts in both family medicine and pharmacy that were commonly encountered in both professions' daily practice. Participating APA pharmacists and family physicians reviewed the cases and responded with likely diagnoses, recommended treatments, and reported confidence in therapeutic choices. The responses of 18 APA pharmacists and 9 family physicians in community practices were analyzed.

Results

There were no significant differences in diagnostic accuracy, therapeutic accuracy, confidence in diagnostic choices, and confidence in therapeutic choices between APA pharmacists and family physicians to these common ambulatory presentations.

Conclusions

This study provides preliminary insights regarding the capabilities of pharmacists in the assessment of common ambulatory community conditions and suggests that APA pharmacists are making similar diagnostic and therapeutic decisions to family physicians. Future research could focus on examining the performance of pharmacists trained in different pharmacy education models, as well as their ability to provide clinical assessment in other specialties, or in more uncommon clinical scenarios.

Improving antimicrobial use through better diagnosis: The relationship between diagnostic stewardship and antimicrobial stewardship

Antimicrobial stewardship programs (ASPs) exist to optimize antibiotic use, reduce selection for antimicrobial-resistant microorganisms, and improve patient outcomes. Rapid and accurate diagnosis is essential to optimal antibiotic use. Because diagnostic testing plays a significant role in diagnosing patients, it has one of the strongest influences on clinician antibiotic prescribing behaviors. Diagnostic stewardship, consequently, has emerged to improve clinician diagnostic testing and test result interpretation. Antimicrobial stewardship and diagnostic stewardship share common goals and are synergistic when used together. Although ASP requires a relationship with clinicians and focuses on person-to-person communication, diagnostic stewardship centers on a relationship with the laboratory and hardwiring testing changes into laboratory processes and the electronic health record. Here, we discuss how diagnostic stewardship can optimize the "Four Moments of Antibiotic Decision Making" created by the Agency for Healthcare Research and Quality and work synergistically with ASPs.

Cognitive and Metacognitive Processes Demonstrated by Pharmacy Students When Making Therapeutic Decisions

Objective. To characterize the types of cognitive and metacognitive processes demonstrated by third-year pharmacy students during a therapeutic reasoning activity.Methods. A qualitative, descriptive study following a think-aloud protocol was used to analyze the cognitive (analytical) and metacognitive processes observed by third-year pharmacy students as they completed a 25-minute therapeutic reasoning activity. Using a deductive codebook developed from literature about reasoning, two independent coders characterized processes from students' audio-recorded, transcribed think-aloud episodes while making therapeutic decisions about simulated clinical cases.Results. A total of 40 think-aloud episodes were transcribed among the cohort. Categorization of the think-aloud transcriptions revealed a series of cognitive analytical and metacognitive processes demonstrated by students during the therapeutic decision-making activity. A total of 1792 codes were categorized as analytical processes, falling into six major themes: 69% gathering information (1232/1792), 13% processing information (227/1792), 7% making assessments (133/1792), 1% synthesizing information (19/1792), 7% articulating evidence (117/1792), and 4% making a recommendation (64/1792). In comparison to gathering information, a much lower frequency of processing and assessment was observed for students, particularly for those that were unable to resolve the case. Students' movement between major analytical processes co-occurred commonly with metacognitive processes. Of the 918 codes categorized as metacognitive processes, two major themes arose: 28% monitoring for knowledge or emotions (257/918) and 72% controlling the planning of next steps or verification of correct information (661/918). Sequencing the codes and co-occurrences of processes allowed us to propose an integrated cognitive/metacognitive model of therapeutic reasoning for students.Conclusion. This study categorizes the cognitive (analytical) and metacognitive processes engaged during pharmacy students' therapeutic reasoning process. The findings can inform current instructional practices and further research into educational activities that can strengthen pharmacy students' therapeutic reasoning skills.

Clinical reasoning by pharmacists: A scoping review

BACKGROUND

Clinical reasoning is considered a core competency for pharmacists, but there is a lack of conceptual clarity that complicates teaching and assessment. This scoping review was conducted to identify, map, and examine evidence on used cognitive processes and their conceptualization of clinical reasoning by pharmacists.

METHODS

In March 2021, seven databases were searched for relevant primary research studies. Included were studies that examined cognitive processes in pharmacists while addressing a clinical scenario in a pharmacy-related setting. Using descriptive analysis, study characteristics, conceptualizations, operationalizations, and key findings were mapped, summarized, and examined. Results were reported using Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews.

RESULTS

From 2252 abstracts, 17 studies were included that examined clinical reasoning in the context of forming a diagnosis (n = 9) or determining medication appropriateness (n = 4). Most studies conceptualized clinical reasoning as a context-dependent cognitive process whereby pharmacists apply and integrate knowledge and clinical experience to interpret available clinical data. Different terms labelled pharmacists' reasoning that showed analytical and intuitive approaches to clinical scenarios, either separately or combined. Medication review studies reported a predominance of analytical reasoning. The majority of diagnosis-forming studies in primary care identified no distinct cognitive reasoning pattern when addressing self-care scenarios.

IMPLICATIONS

This overview reflects a small but growing body of research on clinical reasoning by pharmacists. It is recommended that this competence be taught by explicating and reflecting on clinical reasoning as separate stage of the clinical decision-making process with transparent cognitive processes.

The potential role of community pharmacy staff in reducing patient delay in consulting with symptoms of rheumatoid arthritis: a qualitative study

Background

Rheumatoid arthritis (RA) is a chronic inflammatory arthritis which can cause joint damage and reduced quality of life. Early treatment of RA within 3 months of symptom onset is associated with improved clinical outcomes. However, this window of opportunity is often missed. One important contributing factor is patients with symptoms of RA delaying consulting their general practitioner (GP). Previous research indicates that patients with inflammatory arthritis are likely to visit pharmacies for advice before consulting their GP. Therefore, pharmacists are well positioned to identify patients with symptoms of early inflammatory arthritis and signpost them appropriately. This research examines community pharmacy staff’s knowledge, perceptions, and approaches to management of patients presenting with symptoms of RA in order to identify training needs and other opportunities for intervention to enhance the role of pharmacy staff in the pathway to care.

Methods

Semi-structured interviews were conducted with 19 community pharmacy staff in the West Midlands (UK), during a 12-month period (2017–2018). The interviews were audio-recorded, transcribed, and analyzed using thematic analysis facilitated by NVivo 12.

Results

There was considerable variation in knowledge and perceptions of RA and the need for early treatment amongst pharmacists and other pharmacy staff. The potential role of pharmacists and other pharmacy staff in reducing delay in help-seeking was also discussed. Four themes emerged from thematic analysis: (1) Variations in perceptions and knowledge about RA. (2) The role of the pharmacy in increasing public awareness about RA. (3) The role of the pharmacy staff in facilitating access to the GP. (4) Practical considerations for pharmacy-based interventions.

Conclusion

Variability in knowledge and perceptions of RA amongst pharmacists, and amongst other pharmacy staff will affect effective signposting of suspected RA cases. This study identifies opportunities for enhanced training of community pharmacists and other pharmacy staff in relation to inflammatory arthritis as well as other pharmacy-based interventions, such as public awareness campaigns about RA and other musculoskeletal conditions. Together with existing referral services and other pharmacy-based initiatives this could result in enhanced signposting to GP consultation or other appropriate NHS services for inflammatory symptoms and reduced treatment delay.

Views of Pharmacists and Government Representatives Toward the Pilot Chief Pharmacist System in Chinese Hospitals: A Multicenter Exploratory Qualitative Study

Background

In China, the pharmacy departments of most hospitals have changed their main focus from drug procurement and distribution to providing pharmaceutical care services. Various regions of China have successively implemented the pilot Chief Pharmacist System (CPS) to help improve pharmaceutical care services and rational drug use in hospitals. This study was designed to explore the perspectives of pharmacists and government officials on CPS, including the advantages and barriers to the successful implementation of CPS.

Methods

A qualitative study, based on semi-structured interviews, was conducted from October 1, 2018 to March 1, 2019. The interview data were gathered from 18 pharmacy staff and government representatives working in five distinct regions of China using purposive sampling. A thematic analysis approach and NVivo version 12 Plus was utilized to code and analysis of all interviews.

Results

Five broad themes were identified: the role of the chief pharmacist; their attitudes toward the CPS; the advantages and results of the CPS; the barriers toward CPS; and their suggestions toward CPS. Most of the participants believed that the chief pharmacist played a vital role in a hospital. Under CPS, the hospital pharmacy department pays more attention to prescription review, medication monitoring, and pharmaceutical consultation. However, an insufficient number of pharmacy personnel, unclear authority, and inadequate salaries were the main barriers to the implementation of the CPS.

Conclusion

The attitudes of most of the participants were found to be positive toward CPS in China. The CPS can enhance the prestige of the hospital pharmacy department, improve the quality of hospital pharmaceutical care services, and promote rational drug use. Nevertheless, certain barriers highlighted in this study should be addressed promptly.

The CombiConsultation: a new concept of sequential consultation with the pharmacist and practice nurse/general practitioner for patients with a chronic condition

The primary health care system is generally well organized for dealing with chronic diseases, but comprehensive medication management is still a challenge. Studies suggest that pharmacists can contribute to effective and safe drug therapy by providing services like a clinical medication review (CMR). However, several factors limit the potential impact of a CMR. Therefore, we propose a new pharmaceutical care service for patients with a chronic condition: the CombiConsultation. The CombiConsultation is a medication evaluation service conducted by the (community) pharmacist and either the practice nurse or general practitioner. It consists of 3 steps: medication check, implementation and follow-up. The pharmacist primarily focusses on setting treatment goals for 1 or 2 drug-related problems in relation to a specific chronic condition. In this manuscript we describe the process and characteristics of the CombiConsultation. We compare the CombiConsultation with the CMR and explain the choices made and the implications for implementation.

Clinical Judgement Analysis: An innovative approach to explore the individual decision-making processes of pharmacists

BACKGROUND

Pharmacy stands increasingly on the frontline of patient care, yet current studies of clinical decision-making by pharmacists only capture deliberative processes that can be stated explicitly. Decision-making incorporates both deliberative and intuitive processes. Clinical Judgement Analysis (CJA) is a method novel to pharmacy that uncovers intuitive decision-making and may provide a more comprehensive understanding of the decision-making processes of pharmacists.

OBJECTIVES

This paper describes how CJA potentially uncovers the intuitive clinical decision-making processes of pharmacists. Using an illustrative decision-making example, the application of CJA will be described, including: METHOD: An illustrative study was used, applying an established method for CJA. The decision to initiate anticoagulation, alongside appropriate risk judgements, was chosen as the context. Expert anticoagulation pharmacists were interviewed to define and then refine variables (cues) involved in this decision. Decision tasks with sixty scenarios were developed to explore the effect of these cues on pharmacists' decision-making processes and distributed to participants for completion. Descriptive statistical and regression analyses were conducted for each participant.

RESULTS

The method produced individual judgement models for each participant, for example, demonstrating that when judging stroke risk each participant's judgements could be accurately predicted using only 3 or 4 out of the possible 11 cues given. The method also demonstrated that participants appeared to consider multiple cues when making risk judgements but used an algorithmic approach based on one or two cues when making the clinical decision.

CONCLUSION

CJA generates insights into the clinical decision-making processes of pharmacists not uncovered by the current literature. This provides a springboard for more in-depth explorations; explorations that are vital to the understanding and ongoing development of the role of pharmacists.

Exploring community pharmacists' clinical decision-making using think aloud and protocol analysis

BACKGROUND

Clinical decision-making (CDM) is the dynamic process used to gather, interpret and evaluate data to select an evidence-based choice of action. As the role of the pharmacist becomes more patient-focused, effective CDM skills are increasingly vital to achieve patient outcomes centred on quality, safety and efficacy.

OBJECTIVE

To examine how community pharmacists reason through a clinical problem and what factors assist or hinder decision-making.

METHOD

Fifteen New Zealand registered community pharmacists in central Auckland were presented with a bacterial conjunctivitis case. Think Aloud and protocol analysis were employed to examine pharmacists' cognitive processes when working through the case. Factors that affect CDM were explored through semi-structured interviews and analyzed using thematic analysis.

RESULTS

Pharmacists used pattern recognition and analytical reasoning to diagnose and recommend treatment. Three main factors affecting CDM were: 1. community pharmacy environment, where pharmacy size and layout prevented patient privacy; 2. clinical knowledge, which was outdated and limited by poor access to up-to-date resources; and 3. patient factors, where CDM was affected by time, patient's attitudes, and language barriers. When uncertain, pharmacists typically referred patients to their GP to ensure patient safety and believed offering treatment was not within their scope of practice.

CONCLUSION

Pharmacists used dual processing when encountering a familiar case. Further research is required to explore how pharmacists apply CDM when exposed to less familiar, more complex cases presenting greater ambiguity. Barriers in community pharmacy deter effective CDM skills and could inhibit community pharmacists from fulfilling their expanding role within the modern healthcare system.

The role of non-technical skills in community pharmacy practice: an exploratory review of the literature

BACKGROUND

Non-technical skills (NTS) are the cognitive and social skills that complement technical skills in safe and efficient practice, and include leadership, teamwork, task management, decision-making and situation awareness. Other areas within healthcare have heavily invested in producing taxonomies to aid training and assessment of NTS within their disciplines, and have found them to be essential for improving patient safety. In pharmacy, no validated taxonomy has been produced, nor has the existing literature been appraised to aid the future development of a validated taxonomy.

OBJECTIVE(S)

To examine the literature on NTS within a community pharmacy setting and establish the research conducted thus far on each NTS and how they are applied by community pharmacists.

METHODS

A literature search of six electronic databases (EMBASE, PsychINFO, Medline, SCOPUS, CINAHL Plus and HMIC) using the generic list of NTS identified in previous studies. Only empirical studies were included. Examples of behaviours or skills were extracted and categorised within each NTS.

KEY FINDINGS

Seventeen studies were identified that contained one or more examples of NTS specific to community pharmacy practice. Altogether, 16 elements were extracted. Four elements were identified within leadership and task management. A further three were identified within situation awareness and decision-making, and a final two within teamwork and communication.

CONCLUSION

A framework consisting of the skills and how they're applied has been presented which describe the NTS required by community pharmacists from the published literature. This framework can provide a foundation for further investigation into NTS use within pharmacy practice.

Educational needs of community pharmacy staff in minor ailment service delivery: A systematic scoping review

BACKGROUND

Minor ailment services (MASs) are structured, protocol driven pharmacy services established locally or nationally. Community pharmacy staff may benefit from education and training to deliver MASs. Our objective was to examine the evidence regarding training, education, and assessment requirements associated with the delivery of MASs by community pharmacists and other community pharmacy staff.

METHODS

Two independent literature search strategies were conducted to examine the grey literature and scientific literature. Inclusion criteria consisted of English written literature related to the training of pharmacists, medicine counter assistants (MCAs), pharmacy technicians, and pharmacy students in the context of MASs.

RESULTS

Sixty-six grey literature records (n = 57) and scientific articles (n = 9) met inclusion criteria. Most trainings targeted community pharmacists and focused on clinical care aspects that did not include guidance on service parameters and MAS delivery. Training lacked uniformity and varied in terms of time commitment, cost, curricula, and assessment processes. Limited training was identified for community pharmacy staff, particularly MCAs.

IMPLICATIONS

MAS training is primarily provided for community pharmacists, with scant MAS training for community pharmacy support staff. Furthermore, existing training for any stakeholder group did not include guidance pertaining to service delivery. A structured training approach for the entire community pharmacy team is recommended to promote MAS outcomes and deliver a robust, high quality service. Detailed protocols and guidelines may be needed to ensure skilled MAS providers can deliver quality patient care.

Factors affecting community pharmacist work: A scoping review and thematic synthesis using role theory

Many community pharmacists ideologically support recent changes to their roles in primary healthcare. However, their antithetical resistance towards practice change could have systemic causes (i.e. role stresses), which may account for increased job dissatisfaction, burnout, and job turnover in the profession. Deeper comprehension was sought using a role theory framework.

OBJECTIVE

To identify factors leading to role stresses and strain responses for community pharmacists, and to create a framework for community pharmacist role management.

METHOD

PubMed, Scopus and Web of Science databases were searched for qualitative studies identifying community pharmacist role stress and strain using scoping review methodology from 1990 to 2019. Content and thematic analysis using the framework method was performed, and themes were reported using thematic synthesis.

RESULTS

Screening of 10,880 records resulted in 33 studies identified, with 41 factors categorised into four domains: Interpersonal Interactions, Social Setting, Individual Attributes, and Extra-Role. All role stresses were present. Reported role strains suggest role system imbalance.

CONCLUSION

Community pharmacists are in a multifactorial transitional environment. Reported role stresses may be a function of past pharmacist roles and increased role expectations, amplified by many requisite interactions and individual pharmacist characteristics. Social science theories were found to be applicable to the community pharmacy setting.

Community pharmacists' and residents' decision making and unmet information needs when completing comprehensive medication reviews

OBJECTIVE

To (1) characterize community pharmacists' and community pharmacy residents' decision making and unmet information needs when conducting comprehensive medication reviews (CMRs) as part of medication therapy management and (2) explore any differences between community pharmacists and community pharmacy residents in CMR decision making and unmet information needs.

DESIGN

Thirty-to 60-minute semistructured interviews framed using a clinical decision-making model (CDMM) were conducted with community pharmacists and residents.

SETTING AND PARTICIPANTS

Participants were recruited from practice-based research networks and researchers' professional networks. Eligible participants had completed or supported the completion of at least 2 CMRs in the last 30 days.

OUTCOME MEASURES

Two researchers independently coded transcripts using a combination of inductive and deductive methods to identify themes pertaining to community pharmacists' and residents' decision making and unmet information needs in the provision of CMRs. Discrepancies among researchers' initial coding decisions were resolved through discussion.

RESULTS

Sixteen participants (8 pharmacists and 8 residents) were interviewed. Themes were mapped to 5 CDMM steps. Participants primarily used subjective information during "case familiarization"; objective information was secondary. Information used for "generating initial hypotheses" varied by medication therapy problem (MTP) type. During "case assessment," if information was not readily available, participants sought information from patients. Thus, patients' levels of self-management and health literacy influenced participants' ability to identify and resolve MTPs, as described under "identifying final hypotheses." Finally, participants described "decision-making barriers," including communication with prescribers to resolve MTPs. Although pharmacist and resident participants varied in the types of MTPs identified, both groups cited the use and need of similar information.

CONCLUSION

Community pharmacists and residents often rely primarily on patient-provided information for decision making during CMRs because of unmet information needs, specifically, objective information. Moreover, confidence in MTP identification and resolution is reduced by communication challenges with prescribers and limitations in patients' ability to convey accurate and necessary information.

Pharmacists' advice and clinical reasoning in relation to cardiovascular disease risk factors - A vignette case study

BACKGROUND

Pharmacists are increasingly providing public health services like the screening and monitoring for cardiovascular disease risk factors. Information on risk factors should be integrated into an assessment of absolute cardiovascular disease risk. Limited information is available on how pharmacists interpret test results and information related to cardiovascular disease risk factors.

OBJECTIVE

To investigate the potential advice to clients featured in vignette case studies and reasoning of pharmacists in relation to multiple cardiovascular disease risk factors.

METHODS

Three vignette case studies representing clients with varying degrees of absolute cardiovascular disease risk who requested blood pressure and cholesterol level testing and related advice were designed and distributed to practicing pharmacists. Vignettes contained all necessary information for absolute cardiovascular disease risk assessment. Two open ended questions asked what advice pharmacists would provide and what influenced their decisions to give specific advice. Responses were analysed using content analysis and assessed for appropriateness in relation to cardiovascular guidelines.

RESULTS

Replies of twenty-nine pharmacists were analysed. Advice to hypothetical clients was mainly appropriate when it concentrated on lifestyle modifications. Pharmacists' reasoning indicated a focus on individual risk factors in their decision making on advice rather than consideration of absolute cardiovascular disease risk, which resulted in inappropriate recommendations of referral and follow up.

CONCLUSION

Advice provided in relation to case studies and underlying clinical reasoning indicate potential knowledge gaps, anchoring bias and a framing effect in how pharmacists interpret multiple cardiovascular disease risk factors.

Impact of Medical Care on Symptomatic Drug Consumption and Quality of Life in Headache: A One-Year Population Study

Background: Chronic headache is one of the most common pain conditions, often leading to symptomatic drug overuse. The aim of this study was to provide data on symptomatic drug consumption in an Italian outpatient population and to describe how the clinical picture of headache may change after headache experts take charge of the care of affected individuals.

Methods: A total of 199 adults complaining of chronic headache were recruited through 32 pharmacies in the Pavia health district. Participants underwent four evaluations: a baseline assessment (T0) and three follow-up evaluations performed by a neurologist at 3, 6, and 12 months (T3, T6, and T12, respectively). On each occasion, they underwent a complete neurological assessment and received therapeutic adjustments to achieve better management of their headache.

Results: On the basis of a preliminary telephone interview, the prevalence rates of chronic headache and medication overuse headache (MOH) were 16 and 12%, respectively. At 12 months of follow-up, we observed a significant decrease in the frequency of attacks (T0: 9 ± 9/month vs. T12: 2 ± 2/month; p < 0.001), in the number of days/month with headache (T0: 11 ± 9 vs. T12: 4 ± 4; p < 0.001) and in single attack duration (T0: 34 ± 30 h vs. T12: 10 ± 19 h; p < 0.001). Careful headache management resulted in a significant decrease in analgesic consumption (T0: 12 ± 16 vs. T12: 4 ± 6 doses/month; p = 0.014) and a significant increase in quality of life, measured using the Migraine Disability Assessment Scale (MIDAS) and Headache Under-Response to Treatment (HURT) scales (p < 0.001).

Conclusions: Headache management by a specialist is more effective than self-treatment, resulting in an overall benefit for headache patients.

A systematic review of community pharmacies' staff diagnostic assessment and performance in patient consultations

BACKGROUND

Increases in patients seeking advice at pharmacies has led to pharmacy staff engaging in diagnostic behaviours. Approaches to diagnosis include using mnemonics and clinical reasoning.

OBJECTIVES

The primary aim of this review was to assess the degree to which the criteria researchers use to evaluate diagnostic performance in pharmacy consultations, in studies that have simulated patients or vignettes, conform with a clinical reasoning and a mnemonic framework. A secondary aim of the review was to characterize staff performance in the studies, based on the authors' comments of their results.

METHODS

MEDLINE, EMBASE and Web of Science were searched between October 2016 and April 2017. Only peer-reviewed studies assessing pharmacy staff's diagnostic performance using simulated patients or vignettes were eligible for inclusion. Data were extracted about how each study's criteria conformed with clinical reasoning and mnemonic frameworks. A scoring system between 0 and 4 was devised to determine the degree to which studies aligned to these two approaches. Risk of bias was assessed using the NHI Study Quality Assessment Tools. The review was registered in PROSPERO with identification number CRD42017054827.

RESULTS

Sixty-eight studies (55 cross-sectional, 11 educational interventions and 2 RCTs) with sample sizes between 10 and 2700 were included in the review. Most studies were of poor or fair quality. Performance of pharmacy staff was overwhelmingly reported as poor by study authors. This was the case regardless of geography, scenario used, or assessment framework adopted. Scrutiny on how authors arrived at these conclusions revealed that mnemonic criteria were employed to assess pharmacy staff's diagnostic performance rather than a clinical reasoning approach.

CONCLUSIONS

Potentially important aspects of the decision-making process, such as clinical reasoning, were left unexplored. The number and geographic distribution of the included studies is a strength of this review; however, a validated tool was not employed.

Clinical decision-making: An essential skill for 21st century pharmacy practice

Clinical decision-making skills are recognized as a central component of professional competency but are under-developed in pharmacy compared to other health professions. There is an urgent need for a comprehensive understanding of how pharmacists can best develop and use therapeutic decision-making skills in clinical practice. The aims of this commentary are to define clinical decision-making in pharmacy practice, and to present a model for clinical decision-making that aligns with a philosophical framework for pharmacy practice. The model has utility in education programs for pharmacists and provides a framework for understanding patient-facing clinical services in practice.
