Background: Simulation is a way of learning skills in life like situations that are not real. Simulation based training according to many studies turned out to be effective method in skill development. In this study we have used bench top models available in our institute with simulated patients, which are accessible, and cost effective. The use of simulation in Graduate Medical Education has evolved significantly over time, particularly during the past decade. The applications of simulation include training budding surgeons in technical and non-technical skills and better prepared to face clinical situations.

Methods: After 5 days of focused group discussion, 60 interns were asked to perform the two basic tasks in bench models attached to simulated patents. Skills assessed by pre-test, post-test and feedback module created for the 2 tasks. Scores was compared and analyzed, at the end of the module by summative assessment. Tasks were graded to100 point system, using rubrics and difference calculated using pair t test.

Results: Mean of the skill score in pre-test 78.26±5.58, range found to be 86-73. There was significant improvement in post test score in which 86.54±4.41, range 97-66. t was found to be 5.5256, a significant improvement, and p value found in post-test 0.0002.

Conclusions: Skill development with Mannequins and Standardized patients is found effective in training the interns. In addition to developing technical and non-technical skills, interns also get to communicate with simulated patients, which will make them more competent.
