Self-Instruction Video Versus Face-to-Face Instruction of Pharmacy Students' Skills in Blood Pressure Measurement

A modern approach to clinical skill education is the use of educational videos, yet there is a shortage of literature investigating the effect of self-instruction videos (SIVs) in pharmacy students. Therefore, our objective was to investigate whether an SIV is non-inferior compared to face-to-face instruction (FTFI) in acquiring blood pressure measurement skills. The participants in this randomized controlled study were pharmacy students. The control group was taught by FTFI, while the intervention group watched an SIV. Before and after the instruction, the participants' performance was assessed by an objective structured clinical examination (OSCE). The participants completed a self-assessment survey before each OSCE session. Moreover, the participants' perception and satisfaction were assessed using another survey. The OSCE score and self-assessment score increased significantly from pre- to post-instruction in both groups. The SIV was non-inferior compared to FTFI in terms of the OSCE score, considering a predefined non-inferiority margin of -10%. The participants' self-assessment yielded inconclusive results for non-inferiority. Both instructional approaches were well received. Considering our findings, SIVs might be a valuable option for teaching pharmacy students' blood pressure measurement skills. However, depending on the skill intended to be taught, a combination of an instructional video with instructor-led teaching may be necessary.
