Investigating pharmacy students clinical reasoning of antimicrobial stewardship cases using a qualitative, think-aloud methodology

Abstract

Abstract Introduction Future healthcare workers’ education must include antimicrobial stewardship (AMS) clinical decision-making to achieve optimal clinical outcomes and to treat and prevent infection in a manner that minimises the effects of antimicrobial resistance (AMR) and is safe for patients. Clinical reasoning is an important cognitive process that is essential to evaluate and manage a patient’s medical problem.[1] This study aimed to evaluate the cognitive processes and clinical reasoning skills of pharmacy students when they review AMS cases, as well as identify any existing knowledge gaps in this area that need to be addressed. Methods This qualitative study used a case study approach, in which a sample (n=13) of Master of Pharmacy (MPharm) students in an Irish University were recruited to interpret three patient infection cases. Convenience sampling of MPharm students by email invitation was conducted and students took part voluntarily. Semi-structured interviews were conducted, recorded and transcribed verbatim. A think-aloud procedure with verbal protocol analysis was adopted to determine students’ decision-making processes and clinical reasoning.[2] Thematic analysis was used to analyse interview data. Results Interviews were conducted with 13 students (5 male, 8 female), all aged 22-27 years old. Overall, students interpreted and reasoned through the cases following a structured approach. Some students adopted different approaches to clinical decision-making and did not always follow all the steps outlined in the clinical reasoning cycle. Within the clinical decision-making process, common themes were identified, as outlined in Table 1. Some knowledge gaps were reported by students, including antibiotic prophylaxis, microorganisms, AMS measures, guideline use, soft tissue infection management, and IV-to-oral switch. Conclusion This study provides interesting findings on students’ interpretation and review of infection management and AMS principles which could inform the curriculum development of pharmacy education in AMR and AMS. Educators should consider introducing opportunities to develop clinical reasoning skills to support learning on AMS concepts, particularly in challenging areas such as microbiology, and interpretation and application of guidelines. A limitation of the study is that it was conducted with pharmacy students from one university programme. A strength of the study is the think-aloud methodology which provides in-depth detail on students clinical reasoning thought processes and skills.
