A value-based evaluation of minimally invasive hysterectomy approaches

Abstract

BackgroundWith surgical care contributing to the rising healthcare costs around the globe, quantifying the value of surgical modalities is critical to pushing healthcare systems in the direction of greater sustainability. The purpose of this study was to assess and compare the value of minimally invasive hysterectomy approaches, as defined by operative outcomes and patient satisfaction relative to direct hospital costs.MethodsSequential mixed methods; retrospective chart review of all women (N = 2689) ≥ 18 years old who underwent hysterectomy for benign conditions from 2011 through 2013 at a suburban hospital in Maryland, USA; a mail survey of the same population was administered in June to October 2015. Procedures included laparoscopic supracervical hysterectomy (LSH), robotically assisted laparoscopic hysterectomy (RALH), total laparoscopic hysterectomy (TLH), laparoscopically assisted vaginal hysterectomy (LAVH), total vaginal hysterectomy (TVH), and laparoscopic retroperitoneal hysterectomy (LRH), a procedure that incorporates retroperitoneal dissection and ligation of the uterine arteries at their vascular origin. We estimated the value of each procedure by dividing quality over direct hospital costs, where quality was quantified by creating a summary composite score of the average operating time, estimated blood loss, complication and conversion rates, and patient satisfaction.ResultsThe majority of LRH and RALH procedures were performed by high-volume surgeons, while the majority of LSH and TVH procedures were performed by low-volume surgeons. RALH had the highest postoperative complication rate (11.4%; p < .0001). TVH had the highest intraoperative complication rate (9.6%; p < .0001) but lowest postoperative complication rate (1.8%; p < .0001). LRH had the shortest operating time (71.2 min; p < .0001) and lowest intraoperative complication rates (2.1%; p < .0001). LRH and TVH were the least costly ($4061 and $6416, respectively), while RALH was the most costly ($9354). LRH had the highest combined patient satisfaction score, followed by RALH, while TLH, LAVH, TVH, and LSH averaged similar scores.ConclusionLRH, TVH, and LAVH yielded the highest value scores; LSH, TLH, and RALH yielded the lowest. Healthcare costs continue to escalate, in large part due to innovations in medical technology. For healthcare stakeholders seeking to control costs without sacrificing quality, it is critical to operationalize the value of varying surgical techniques, including measures of surgeon experience, operative outcomes, costs, and patient satisfaction.
