Effect of Preoperative Simulator Warmup on Intraoperative Robotic Surgical Skills
- Conditions
- Robotic Hysterectomy (Benign Indications/Early-stage Cancer)
- Interventions
- Other: Preoperative warm-up on simulator
- Registration Number
- NCT01969487
- Lead Sponsor
- Johns Hopkins University
- Brief Summary
Surgical residents and fellows acquire operative knowledge and skills by assisting attending surgeons in the operating room. Previous research has shown that practising technical skills prior to operating on patients can improve how skillfully laparoscopic surgery can be performed. Although an increasingly large number of patients are undergoing robotic hysterectomy and other robotic surgical procedures, little is known on how to ensure patient safety and treatment effectiveness when trainee surgeons participate in the operating room. Our study aims to determine the impact of immediate preoperative warm-up on a robotic surgery simulator by gynecologic surgical trainees on their intraoperative performance and on patient outcomes. The investigators are randomly assigning gynecologic surgical trainees at a major academic medical center to either warm-up immediately before surgery on a robotic surgery simulator or to not warm-up. The attending surgeon supervising the trainee in the operating room is unaware of whether the trainee was assigned to warm-up or no warm-up. The investigators will compare standard robotic surgical skills assessments of the trainees by the supervising attending surgeons and patient outcomes in the two groups.

Group Intervention Description Preoperative warm-up on simulator Preoperative warm-up on simulator Trainees perform standard practice tasks programmed into a robotic surgical simulator immediately before the surgery.
- Primary Outcome Measures
Name Time Method Surgical skill metrics Assessed during the surgery (scheduled immediately following warm-up/no warm-up) Computed using surgical tool motion and/or video of procedure.
Global rating score - OSATS approach Assessed during the surgery (scheduled immediately following warm-up/no warm-up) Global rating scores assigned by the supervising surgeon immediately after each study surgical procedure. Global rating scores use two different approaches - the Objective Structured Assessment of Surgical Skills and the Global Evaluative Assessment of Robotic Surgery.
Global rating score - GEARS approach Assessed during the surgery (scheduled immediately following warm-up/no warm-up) Global rating scores assigned by the supervising surgeon immediately after each study surgical procedure. Global rating scores use two different approaches - the Objective Structured Assessment of Surgical Skills (OSATS) and the Global Evaluative Assessment of Robotic Surgery (GEARS).
- Secondary Outcome Measures
Name Time Method Length of hospital stay We will follow patients in the study for the duration of their hospital stay; an anticipated average of about 5 days. Estimated blood loss Intraoperative Change in hematocrit Postoperative days 1, 2, and 3 Operative time Intraoperative Readmission or emergency room visit 6 weeks after discharge from hospital (following initial admission for surgery)
