(15 junior residents, postgraduate year (PGY) 1 - 2 and 11 senior residents, PGY 3 - 4).Abstract: INTERVENTION: We developed a simple, low-cost laparoscopic ovarian cystectomy simulator and incorporated it into our simulation curriculum. The simulation was directed at junior residents with instruction and immediate feedback in a scheduled simulation session once during the academic year. At the end of the year resident skills assessment, all levels were recorded with video using this model to assess construct validity between junior and senior residents. Resident performance was later evaluated and scored by two blinded, experienced laparoscopists using a validated Objective Structured Assessment of Technical Skills (OSATS).Abstract: MEASUREMENT & MAIN RESULTS: Each resident received a unique identification number and the simulated laparoscopic ovarian cystectomy procedure was filmed during the end of the year assessment. Two blinded raters evaluated the video of each resident with the modified global rating scale (OSATS), utilizing 5 of the 7 domains (respect for tissue, time and motion, instrument handling, flow of operation and knowledge of specific procedure). An average of the two ratings was computed for each domain and comparison was made using the Mann-Whitney U test. Inter-rater reliability was calculated using the Kendall's tau beta correlation coefficient. Construct validity was determined by comparing the rank scores of the junior to senior residents in each domain. Construct validity and inter-rater reliability was demonstrated in all of the measured domains except for respect for tissue.Abstract: CONCLUSION: This simple, low-cost model can be used to teach important laparoscopic ovarian cystectomy skills. Construct validity discriminating between junior and senior residents was demonstrated using this model.Abstract: Copyright � 2017. Published by Elsevier Inc.
