Surgical Complications and Hospital Costs in Robot-Assisted Versus Conventional Laparoscopic Hysterectomy With Concurrent Sacrocolpopexy: Analysis of the Nationwide Readmissions Database.

OBJECTIVES:Despite increasing use of robotic technology for minimally invasive hysterectomy with sacrocolpopexy, evidence supporting the benefits of these costly procedures remains inconclusive. This study aimed to compare differences in perioperative complications, 30-day readmissions, and costs between robot-assisted and conventional laparoscopic hysterectomy with concurrent sacrocolpopexy using a large national database. METHODS:Using the 2009-2015 Nationwide Readmissions Database and procedure codes, we identified patients who underwent a robot-assisted or conventional laparoscopic hysterectomy with sacrocolpopexy. We measured in-hospital perioperative complications using diagnosis and procedure codes and measured 30-day readmissions based on patient linkages across hospitalizations. Hospital costs were estimated using charges and cost-to-charge ratios. These outcomes were compared between robot-assisted and conventional laparoscopic procedures using bivariate and multivariable regression analysis. RESULTS:Our weighted sample included a total of 7,675 patients. Major perioperative complications occurred in 6.7% of robot-assisted and 11.2% of conventional laparoscopic procedures (unadjusted P < 0.001; adjusted odds ratio, 0.69; 95% confidence interval, 0.51-0.93; P = 0.02). Hospital costs were higher in robot-assisted than in conventional laparoscopic procedures (respective median costs, $16,367 vs $13,898; P < 0.001), with an adjusted cost ratio of 1.24 (95% confidence interval, 1.17-1.31; P < 0.001). The risk of 30-day readmission was similar between robot-assisted and conventional laparoscopic procedures. CONCLUSIONS:Nationally representative data suggest that, in laparoscopic hysterectomy with sacrocolpopexy, the robot-assisted approach is associated with a lower risk of perioperative complications, despite higher costs, compared with the conventional one. The risk of 30-day readmission was similar between the robot-assisted and conventional laparoscopic approaches.
