Pre-clerkship procedural training in venipuncture: a prospective cohort study on skills acquisition and durability

Abstract

BACKGROUND: The effectiveness of simulation-based training for skill acquisition is widely recognized. However, the impact of simulation-based procedural training (SBPT) on pre-clerkship medical students and the retention of procedural skills learned through this modality are rarely investigated. METHODS: A prospective cohort study was conducted among pre-clerkship medical students. Learners underwent SBPT in venipuncture in the skills laboratory. Assessments were conducted at two main points: 1) immediate assessment following the training and 2) delayed assessment one year after training. Learner self-assessments, independent assessor assessments for procedural competency, and communication skills assessments were conducted in both instances. The students were assessed for their competency in performing venipuncture by an independent assessor immediately following the training in the simulated setting and one-year post-training in the clinical setting, using the Integrated Procedural Protocol Instrument (IPPI). The student's communication skills were assessed by standardized patients (SP) and actual patients in the simulated and clinical settings, respectively, using the Communication Assessment Tool (CAT). RESULTS: Fifty-five pre-clerkship medical students were recruited for the study. A significant increase was observed in self-confidence [mean: 2.89 SD (Standard Deviation) (0.69)] and self-perceived competency [mean: 2.42 SD (0.57)] in performing venipuncture, which further improved at the delayed assessment conducted in the clinical setting (p < 0.001). Similarly, the IPPI ratings showed an improvement [immediate assessment: mean: 2.25 SD (1.62); delayed assessment: mean: 2.78 SD (0.53); p < 0.01] in venipuncture skills when assessed by an independent assessor blinded to the study design. A significant difference (p < 0.01) was also observed in doctor-patient communication when evaluated by SPs [mean: 2.49 SD (0.57)] and patients [mean: 3.76 SD (0.74)]. CONCLUSION: Simulation-based venipuncture training enabled students to perform the procedure with confidence and technical accuracy. Improved rating scores received at a one-year interval denote the impact of clinical training on skills acquisition. The durability of skills learned via SBPT needs to be further investigated.
