Cost impact analysis of enhanced recovery after minimally invasive gynecologic oncology surgery

Abstract

ObjectiveThe implementation of a peri-operative care program based on enhanced recovery after surgery principles for minimally invasive gynecologic oncology surgery led to an improvement in same day discharge from 29% to 75% at our center. This study aimed to determine the program’s economic impact.MethodsOur initial enhanced recovery quality improvement program enrolled consecutive patients undergoing minimally invasive hysterectomy at a single center during a 12-month period and compared them to a pre-intervention cohort. The primary outcome was overall costs. The secondary outcomes were surgical and post-operative visit costs. The surgical visit costs included pre-operative and operating room, post-operative stay, pharmacy, and interventions costs. The 30-day post-operative visit costs included clinic and emergency room, and readmission costs. The costs for every visit were collected from the case-cost department and expressed in 2020 Canadian dollars (CAD).ResultsA total of 96 and 101 patients were included in the pre- and post-intervention groups, respectively. The median total cost per patient for post-intervention was $7252 compared with $8381 pre-intervention (p=0.02), resulting in a $1129 cost reduction per patient. The total cost for the program implementation was $134 per patient for a total cost of $13 106. The median post-operative stay cost was $816 post-intervention compared with $1278 pre-intervention (p<0.05). Statistically significant savings for the post-intervention group were also found for operative visit, operating room costs, and pharmacy (p<0.05). On multivariate analysis, surgical approach was the only factor associated with operating room costs, whereas both surgical approach and group (pre- vs post-intervention) impacted the total and post-operative stay costs (p<0.05).ConclusionIn addition to increasing the same day discharge rate after minimally invasive gynecologic oncology surgery, an enhanced recovery-based peri-operative care program led to significant reductions in cost.
