Abstract [en]

Objective: The study objective was to compare total costs for hospital stay and postoperative recovery for two groups of women who underwent fast track abdominal benign hysterectomy, one group under general anesthesia, the other under spinal anesthesia. Costs were evaluated in relation to health related quality of life.

Study Design: Costs of treatment using data from a randomized multicenter study at five hospitals in Sweden were analyzed retrospectively. Of 180 women scheduled for benign abdominal hysterectomy; 162 were randomized for the study, 80 allocated to general anesthesia and 82 to spinal anesthesia.

Results: Total costs (hospital costs plus costs reduced productivity costs) were lower for the spinal anesthesia group. Women who had spinal anesthesia had a faster recovery measured by health related quality of life and QALYs gained in postoperative month one.

Conclusion: Use of spinal anesthesia for fast track benign abdominal hysterectomy was more cost-effective than general anesthesia.

Abstract [en]

Introduction: Hysterectomy is the most common major gynecological operation in the Western World and approximately 5000 benign hysterectomies are performed in Sweden every year. Consequently it is a surgical procedure that affects many women. The procedure comprises challenges concerning perioperative health care, perceived postoperative symptoms, quality of life aspects and health economics. The concept of fast track is a multimodal strategy to reduce hormonal surgical stress response and achieve an enhanced postoperative recovery and is today considered to be evidence based in relation to colorectal surgery. Spinal anesthesia, as an important part of fast track, provides benefits of extended effect on analgesia and reduced postoperative morbidity. It is reasonable to believe that employing the strategies of fast track including spinal anesthesia could also provide substantial benefits for women requiring surgical removal of the uterus.

Aims: To determine whether duration of hospital stay, presence and intensity of postoperative symptoms, duration of sick leave and cost-effectiveness differ between women undergoing benign fast track abdominal hysterectomy in spinal anesthesia with intrathecal morphine (SA) and in standard general anesthesia (GA).

Material & Methods: 180 women participated in this open randomized multicenter study with five participating hospitals in the southeast region of Sweden. One hundred and sixty two completed the study; 82 women were randomized to SA and 80 to GA. A fast track model comprising premedication without sedatives, intravenous fluid regulation, analgesics based on non-opioids, pre-emptive antiemetic therapy, early enteral nutrition and mobilization and standard criteria for discharge were used. End points were duration of hospital stay, use of analgesics, perceived postoperative symptoms, occurrence of postoperative complications, duration of sick leave and health economic evaluations.

Results: Duration of hospital stay did not differ between the two modes of anesthesia. Vomiting and pruritus occurred significantly more often after SA. Complication rates did not differ between groups. Women with SA experienced less overall discomfort and had a reduced need for opioids postoperatively. Abdominal pain, drowsiness and fatigue occurred less often and with lower intensity among the women in the SA group. Health related quality of life improved faster and the duration of sick leave was shorter in women after SA. Total costs (hospital costs plus costs for productivity loss) were lower for the SA group. Within the first 29 days after hysterectomy the women in the SA group gained more QALYs than women in the GA group.

Conclusions: The duration of hospitalisation after fast track abdominal hysterectomy was less than 50 hours and mode of anesthesia did not influence this. SA displayed considerable advantages regarding postoperative symptoms and recovery. SA was considered cost-effective in comparison with GA due to lower total costs and more QALYs gained. Our study indicates that SA should be recommended as the first choice of anesthesia in benign abdominal hysterectomy.
