About this study
The purpose of this study is to determine the learning curve for each of seven tasks in a virtual reality laparoscopic simulator by medical students.
Read the detailed description
Developing objective methodology for assessing technical skill is paramount to superior surgical training. Alternatives to the traditional apprenticeship model of surgical training are necessary in today's emphasis on cost containment and professional competency.
Metrics are widely employed in virtual environments and provide a yardstick for performance measurement. The current method of defining metrics for medical simulation remains more an art than a science. Many studies have demonstrated that trainees who practice laparoscopic skills in a simulated environment will improve their mastery of those skills when tested in that same environment. Fewer studies have been able to document the learning curve for mastery of tasks in a virtual reality simulator. This study will investigate the learning curve for tasks in a virtual reality laparoscopic simulator.

What is being measured
The primary outcome is the main question the study is designed to answer.
Establish learning curve for each of seven tasks on the simulator.
For each of the module seven modules, the computer automatically measures set parameters. Each measured parameter that is recorded in the simulator will be used in data analysis.
Measured: 6 months
Secondary outcomes (1)
Establish test-retest reliability for each of seven tasks on the simulator.
Measured: 6 months

What does the primary outcome measure?
Establish learning curve for each of seven tasks on the simulator. (time frame: 6 months). It is what the study was designed to measure, not a finding.
