Design outcomes

Primary

Measure	Time frame
The main-objective criterion is the operative performance of the study participants during the final laparoscopic cholecystectomy based on the standardized validated OSATS-criteria. The operative performance of the study participants is measured by two scales. The scale "generic technical skills" covers a range from 6 (min) to 30 points (max). The maximal achievable score of "specific technical skills" is 70 points and the minimal score 14 points. Both scales will be evaluated separately. The OSATS-scores are based on a Gaussian distribution. The scale "specific technical skills" will be applied in a modified way in this study due to its specific circumstances. The criteria "incision & insertion of the port" and " extraction of the gallbladder" refer to surgeries on humans or on living animals and cannot be rated appropriately on the P.O.P.-trainer. Both are replaced by the criteria "knowledge of surgery specific aspects" and "quality of the final product".	—

Secondary

Measure	Time frame
The baseline- and post-test of the VR-trainer is used to demonstrate the differences in achievement between the individual groups with training (group 1/group 2) and without training (group 3). In all groups, data are continuously being collected for each participant on basis of the multimodal standardized training curriculum designed by the Department of MIC. Each individual exercise in the box-trainer is recorded with respect to time and errors. The software of the VR-trainer allows continuous recording of various parameters, which are taken for every participant. Based on the data, learning curves can be displayed for all participants immediately . Using questionnaires and tests various data are recorded for each participant. The questions relate to laparoscopic prior experience and leisure behavior in relation to physical activity and playing computer games and musical instruments. Other parameters such as personality traits and spatial awareness are also taken via questionnaires. Group 2 will receive an additional question in relation to the joint training. Based on the individual data collected, a correlation between the training and test results might be deduced which we will also analyse. The questionnaire allows for evaluation of the training devices and the e-learning instructional films.	—
