Novel indigenous low cost (NICA) model for hands on training of surgical interns in incision and drainage procedure for superficial skin abscess.

Abstract

Background: Surgical education necessitates hands-on training, which poses ethical challenges when practicing on real patients. Simulation training emerges as a pivotal solution, offering a safe and effective environment for skill acquisition. However, existing simulation models often overlook common surgical conditions like superficial skin abscesses. The National Medical Commission advocates for simulation-based training in basic surgical skills, highlighting the need for accessible and cost-effective models. Thus, this study aimed to develop and evaluate a novel Indigenous Cost-effective model for Incision & Drainage (NICA) of subcutaneous abscesses, addressing the gap in surgical education.

Methodology: Following institutional ethics clearance, the study employed Kern's Six-step approach for curriculum development. The NICA model was conceptualized and crafted using locally available, low-cost materials, validated by expert opinion, and implemented in a simulation lab setting. A total of 155 surgical interns underwent training, consisting of didactic video sessions, hands-on practice with the NICA model, and structured assessments. Pre- and post-training evaluations were conducted to measure interns' performance and feedback.

Results: Expert validation confirmed NICA model's fidelity and usefulness. Training 155 surgical interns resulted in significant skill improvements. Pre-training, 33% correctly performed pre-procedural requisites, 46% executed procedural techniques, and 48% performed post-procedural steps accurately. Post-training, these percentages surged to 95%, 97%, and 98%, respectively. Post test score showed significant skill enhancements across all domains (p < 0.05). Intern feedback highlighted increased confidence, satisfaction, and interest in learning, affirming NICA model's effectiveness.

Conclusion: The development and implementation of the NICA model offer a scalable and cost-effective solution for surgical training in resource-limited settings. The model's effectiveness in enhancing interns' skills and confidence underscores its potential to address training needs effectively. The study highlights the significance of simulation-based training in surgical education and advocates for the widespread adoption of indigenous low-cost models to improve surgical skills acquisition.
