Comparative analysis of overall cost and rate of healthcare utilization among apical prolapse procedures.

ABSTRACT

INTRODUCTION AND HYPOTHESIS: The annual cost of prolapse surgeries is expected to grow at twice the rate of population growth. Understanding the economic impact of apical prolapse procedures, including sacrospinous fixation (SSF), abdominal sacrocolpopexy (ASC), and laparoscopic sacrocolpopexy (LSC), is crucial. We aimed to compare overall cost of SSF versus ASC and LSC, as well as health resource utilization, up to 90-day follow-up. METHODS: Truven Marketscan Commercial Claims and Encounter databases 2008-2012 were used to calculate index and 90-day follow-up costs for SSF, ASC, and LSC with/without hysterectomy. Rates of inpatient readmissions, outpatient visits, and emergency room (ER) visits were also calculated during the follow-up period. Statistical analyses were performed using SAS 9.3. RESULTS: There were 17,549 SSF, 6126 ASC, and 10,708 LSC procedures. Mean index cost was lower for SSF (US$10,993) than ASC ($12,763, p < 0.0001) and LSC ($13,647, p < 0.0001). Concurrent hysterectomy impacted costs. Follow-up costs were likewise lower for SSF ($13,916) than ASC ($15,716, p < 0.0001) and LSC ($16,838, p < 0.0001). Lower rates of readmission were reported in SSF (4.22%) than ASC (5.40%, p = 0.0001) and LSC (4.64%, p = 0.0411). The rate of at least one ER visit was also lower for SSF (10.9%) than for ASC (12.0%, p = 0.0170) and comparable with LSC (10.6%, p = 0.0302). CONCLUSIONS: Overall mean costs are significantly lower for SSF than ASC/LSC, as are those for health resource utilization. Besides lower morbidity rates being associated with vaginal procedures, our results demonstrate another reason to consider the increased use of SSF over sacrocolpopexies in apical prolapse surgery.
