Investigation of Simulated Pharmacist Decision Making Involving Prescriptions With a High Probability of Causing Patient Harm

Evaluation of Community Pharmacists' Competences in Identifying and Resolve Drug-Related Problems in a Pediatric Prescription Using the Simulated Patient Method

Background: Drug-related problems (DRPs) are a global issue that impacts the efficacy and safety of the therapy, and pediatric patients are considered to be more vulnerable to DRPs, thus requiring more attention. Community pharmacists (CPs) are in a position that allow them to identify and alleviate these DRPs. Objectives: This study evaluated the ability of CPs in identifying and resolving DRPs in a pediatric prescription. Methods: A cross-sectional study was carried out in 235 community pharmacies to evaluate the ability of CPs working in the Khartoum locality to identify DRPs in a pediatric prescription and how they intervene to resolve these problems. Fifth-final year B. Pharm. Students were selected and trained to act as simulated patients (SPs) for this study. The visits were performed by using a simulated prescription that contains three different types of DRPs. The information obtained from the visits was documented immediately by the SPs after leaving the pharmacy in a data collection form. Results: All planned SPs visits were completed. Of the 235 community pharmacies, only 50 (21.3%) CPs were able to identify at least one of the DRPs. The most common type of DRP identified was the wrong duration of the treatment 19%, followed by the wrong dose 4%. The interventions made by CPs to mitigate the identified DRPs included recalculation and correction of the dose according to weight, which was made by 10 CPs, and correction of the duration, which was done by 45 CPs. None of the CPs who identified the presented DRPs communicated with the physician or referred the SP to the prescriber. The average dispensing time of the CPs was 68.18 ± 36.1 s. Conclusions: The majority of the CPs in the Khartoum locality were unable to identify DRPs in a pediatric prescription. Correction of the dose and duration of treatment were from the attempts of CPs to resolve DRPs. However, no collaboration was observed between CPs and physicians. In general, the practice of CPs in Khartoum locality in this area requires substantial improvement.

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.

Teaching drug utilization review skills via a simulated clinical decision making exercise

BACKGROUND

Drug utilization review (DUR) is a central role of the pharmacist, especially within the community pharmacy setting. Previous literature has shown risk of "alert fatigue", supporting the necessity of pharmacists to utilize a step-wise approach in evaluation of drug therapy during the verification process. Many students are intimidated by this process, and may lack verification practice or experience until their first day as a licensed pharmacist.

EDUCATIONAL ACTIVITY AND SETTING

An innovative skills-based laboratory exercise was developed for third-year pharmacy students to develop DUR skills. Through simulation of patient prescriptions, profiles, and drug information resources, students were tasked with completing a DUR for each patient case. Students were expected evaluate the clinical significance of various drug-related problems, determine if they would or would not dispense the prescription, and were required to provide rationale for their decision.

FINDINGS

This learning activity was well-received by the student population; however, students struggled with the volume of cases along with identifying a solution to the clinical scenario. On average, students required nine minutes per case, which is likely longer than community pharmacists can devote to a single DUR in practice.

DISCUSSION

In response, to student challenges with the activity, the number of cases was condensed to highlight key concepts and cases that facilitated strong discussion. To improve students' approach to the DUR process, faculty developed a vodcast to watch prior to the activity explaining a systematic approach to the DUR process as well as considerations a pharmacist should have.

SUMMARY

Development and integration of an active-learning, simulated dispensing activity allowed students to gain valuable experience completing the DUR process, a foundational community pharmacy practice skill; however, repeated experience should be provided to ensure competency.
