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

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.

Procedural simulation in venipuncture for medical undergraduates and its transfer to the bedside: a cluster randomized study.

Simulation is accepted as an effective method of learning procedural skills. However, the translational outcomes of skills acquired through simulation still warrants investigation. We designed this study to assess if skills laboratory training in addition to bedside learning (intervention group [IG]) would provide better learning results than bedside learning alone (control group [CG]) in the context of venipuncture training. This prospective, cluster-randomized, single-blind study took place at the Faculty of Medicine, University of Kelaniya, Sri Lanka. Seventeen clusters of second-year medical students were randomly assigned to either IG or CG. The IG trained on venipuncture in the skills laboratory, receiving instruction after modified Payton's Four Step Method. Following the training, students of both IG and CG underwent bedside learning for one month. Afterward, students of both groups performed venipuncture on actual patients in a clinical setting. An independent, blinded assessor scored students' performance using the Integrated Procedural Protocol Instrument (IPPI) and a checklist. Patients assessed students' performance with the Communication Assessment Tool (CAT). Eight and nine clusters were randomized to the intervention and control groups, respectively. IG completed significantly more single steps of the procedure correctly (IG: 19.36 ± 3.87 for checklist items; CG: 15.57 ± 4.95; p < 0.001). IG also scored significantly better on IPPI ratings (median: IG: 27 (12) vs. CG: 21 (8); p < 0.001). Rated by patients, students' communication skills did not significantly differ between the two groups. Simulation-based venipuncture training enabled students to perform the procedure on actual patients with a higher technical accuracy than students who learned venipuncture at the bedside. Students were able to transfer the skills acquired through venipuncture training at the skill laboratory to the bedside.

Challenges in Learning Procedural Skills: Student Perspectives and Lessons Learned for Curricular Design.

Phenomenon: Developing foundational clinical procedural skills is essential to becoming a competent physician. Prior work has shown that medical students and interns lack confidence and competence in these skills. Thus, understanding the student's perspective on why these skills are more difficult to acquire is vital for developing and reforming medical curricula. Approach: This study explored procedural skills learning experiences of medical students with qualitative methods. Through purposive sampling, 52 medical students from the third, fourth, and final years were selected for inclusion. Data were collected using six audio-recorded, semi-structured focus group discussions. Transcripts were manually coded and analyzed using inductive content analysis. Findings: Students provided rich and insightful perspectives regarding their experiences in learning procedural skills that fell into three broad categories: 1) barriers to procedural learning, 2) reasons for learning, and 3) suggestions for better learning outcomes. Students described a range of barriers that stemmed from both patient and clinician interactions. Students were reluctant to make demands for their own benefit during clerkships. The most commonly expressed reason for wanting to learn procedural skills was the desire to be a competent and independent intern. The motivators suggested that students felt empathetic toward interns and visualized a successful internship as a learning goal. Participants suggested peer learning, improved teaching of procedural skills, assessments, and feedback to improve their learning. Insights: This study generated valuable information to promote critical reflection on the existing curriculum and pedagogical approaches to procedural skills development. Medical educators need to sensitize the clinical teachers to student perspectives and what students are really learning to make impactful changes to teaching and learning procedural skills. Students' self-advocacy skills and self-directed learning skills need to be developed for them to seek out learning opportunities and to promote life-long learning. Lessons from this study may also apply to curriculum design in general, especially in teaching clinical skills. Empowering the learner and embracing a learner-centered approach to teaching and learning procedural skills will benefit future clinicians and their patients.
