AbstractBackground The Covid-19 pandemic severely affected surgical training as the number of surgeries being done was reduced to a bare minimum. Teaching and training of clinical skills on a simulator are desirable as they may have an even larger role during the Covid-19 pandemic. Commercially available simulators with optimum fidelity are costly and may be difficult to sustain because of their recurring cost. The development of low-cost simulators with optimum fidelity is the need of the hour. Methods We developed animal tissue-based simulators for imparting skills training to surgical residents on some basic and advanced general surgical procedures. Porcine tissue and locally available materials were used to prepare these models. The models were pilot-tested. Standard operating procedures were developed for each skill that was shared with the participants well before the 'hands-on' exercise. An online pre-test was conducted. The training was then imparted on these models under faculty guidance adhering to Covid-19-appropriate behaviour. This was followed by a post-test and participant feedback. The entire exercise was paperless. Results Sixty residents were trained in 10 sessions. Most of the participants were men (44; 73%). The mean pre-test and post-test scores were 40.92 (standard deviation [SD] 6.27) and 42.67, respectively (SD 4.06). Paired sample t-test suggested a significant improvement in the post-test score (p<0.001). The activity and the models were well appreciated by the residents. Conclusion The animal tissue-based indigenous models are easy to prepare, cost-effective and provide optimum fidelity for skill training of surgical residents. In addition to skill acquisition, training on such modules may alleviate the stress and anxiety of the residents associated with the loss of surgical training during a time-bound residency period.
