Health care costs are an important consideration in the decision of hysterectomy routes and robotic surgery is often critiqued for its high cost. We sought to compare the cost of robotic-assisted hysterectomies performed after initial acquisition of the robotic surgical system to cases performed after 5 years of experience. The first 20 patients at a community teaching hospital who underwent robotic-assisted hysterectomy for endometrial cancer by a single gynecologic oncology surgeon were designated Group 1 and 20 patients undergoing robotic hysterectomies 5 years later for the same indication were designated Group 2. Direct hospital costs were divided into operative and non-operative costs. Mean operating room cost and cost of anesthesia per minute for Group 1 were adjusted to Group 2 mean costs. Supply costs were adjusted using the 2015 Consumer Price Index. Baseline characteristics of the groups were comparable. After 5 years of experience, there was a 15.5% [95% CI (-$2865, -$407), p = 0.01] reduction in mean total costs (Group 1 = $10,543, Group 2 = $8907) and a 14.3% [95% CI (-$2378, -$390), p ≤ 0.01] reduction in mean operative costs (Group 1 = $9688, Group 2 = $8304). Significant reductions in procedure time, operating room time, operating room cost, and cost of anesthesia were seen from Group 1 to Group 2. There were no differences in mean non-operative costs, estimated blood loss, cost of supplies or surgeon cost. Experience with robotic-assisted hysterectomies is associated with reduction in costs, which is primarily a result of reduced operative times. This is an important factor when considering costs related to robotic surgery.
