Direct Costs Incurred Among Women Undergoing Surgical Procedures to Treat Uterine Fibroids.

BACKGROUND

Uterine fibroids (UF) affect up to 70%-80% of women by 50 years of age and represent a substantial economic burden on patients and society. Despite the high costs associated with UF, recent studies on the costs of UF-related surgical treatments remain limited.

OBJECTIVE

To describe the health care resource utilization (HCRU) and all-cause costs among women diagnosed with UF who underwent UF-related surgery.

METHODS

Data from the IBM MarketScan Commercial Claims and Encounters database and Medicaid Multi-State database were independently, retrospectively analyzed from January 1, 2009, to December 31, 2015. Women aged 18-64 years with ≥ 1 UF claim from January 1, 2010, to December 31, 2014, a claim for a UF-related surgery (hysterectomy, myomectomy, uterine artery embolization [UAE], or ablation) from January 1, 2010, to November 30, 2015, and continuous enrollment for ≥ 1 year presurgery and ≥ 30 days postsurgery qualified for study inclusion. A 1-year period before the date of the first UF-related surgical claim after the first UF diagnosis was used to report baseline demographic and clinical characteristics. Surgery characteristics were reported. All-cause HCRU and costs (adjusted to 2017 U.S. dollars) were described by the 14 days pre-, peri-, and 30 days postoperative periods, and independently by the inpatient or outpatient setting.

RESULTS

Overall, 113,091 patients were included in this study: commercial database, n = 103,814; Medicaid database, n = 9,277. Median time from the initial UF diagnosis to first UF-related surgical procedure was 33 days for the commercial population and 47 days for the Medicaid population. Hysterectomy was the most common UF-related surgery received after UF diagnosis (commercial, 68% [n = 70,235]; Medicaid, 75% [n = 6,928]). In both populations, 97% of patients had ≥ 1 outpatient visit from 14 days presurgery to 30 days postsurgery (commercial, n = 100,402; Medicaid, n = 9,023), and the majority of all UF-related surgeries occurred in the outpatient setting (commercial, 64% [n = 66,228]; Medicaid, 66% [n = 6,090]). Mean total all-cause costs for patients with UF who underwent any UF-related surgery were $15,813 (SD $13,804) in the commercial population (n = 95,433) and $11,493 (SD $26,724) in the Medicaid population (n = 4,785). Mean total all-cause costs for UF-related surgeries for the commercial/Medicaid populations were $17,450 (SD $13,483)/$12,273 (SD $19,637) for hysterectomy, $14,216 (SD $16,382)/$11,764 (SD $15,478) for myomectomy, $17,163 (SD $13,527)/$12,543 (SD $23,777) for UAE, $8,757 (SD $9,369)/$7,622 (SD $50,750) for ablation, and $12,281 (SD $10,080)/$5,989 (SD $5,617) for myomectomy and ablation. Mean total all-cause costs for any UF-related surgery performed in the outpatient setting in the commercial and Medicaid populations were $14,396 (SD $11,466) and $6,720 (SD $10,374), respectively, whereas costs in the inpatient setting were $18,345 (SD $16,910) and $21,805 (SD $43,244), respectively.

CONCLUSIONS

This retrospective analysis indicated that surgical treatment options for UF continue to represent a substantial financial burden. This underscores the need for alternative, cost-effective treatments for the management of UF.
