Implementation of an Evidence-Based Medicine Curriculum for Postgraduate Emergency Medicine Physician Assistant and Nurse Practitioner Fellows.

Abstract

Introduction: Within physician assistant (PA) education, the inclusion of evidence-based medicine (EBM) is mandatory. Despite existing literature on EBM training methodologies for PA students and emergency medicine (EM) physician residents, there exists a dearth of published data concerning EBM instruction within postgraduate PA EM programs. A pilot study is described providing an overview of implementation of an EBM curriculum in a single-institution postgraduate physician assistant and nurse practitioner emergency medicine fellowship.

Methods: Quantitative data using pre-curriculum and post-curriculum surveys were collected. The curriculum included statistical concept screencasts, required attendance at a journal club with assigned topics for discussion, and used a critical appraisal tool designed to help fellows better analyze and understand the articles being reviewed. Upon graduation, fellows participated in structured interviews to collect qualitative data about the curriculum and application of learned concepts to the clinical setting.

Results: There was a statistically significant improvement in fellows' reported confidence in discussing the medical literature with practicing providers ( P = .02). However, there was no difference in prescores and postscores on EBM knowledge questions or on fellows' feelings of importance of EBM to clinical practice. Qualitative data revealed several themes, including helpfulness of tools provided in the curriculum, appreciation of curricular changes made secondary to fellow suggestions, and reports of improvement in reviewing medical literature and comfort in participation in local journal clubs upon graduation from the fellowship program.

Discussion: Limitations, including small sample size and validity concerns, are discussed. Positive changes were made to the curriculum based on qualitative data collected. The authors advocate for subsequent investigations into this subject within a multi-institutional and multispecialty context, thereby enhancing the breadth of the findings. Nevertheless, this study furnishes the initial accessible substantiation of the viability of introducing an EBM curriculum within this specific demographic.
