Objective:
To compare direct and indirect costs between endometriosis patients who underwent endometriosis-related surgery (surgery cohort) and those who have not received surgery (no-surgery cohort).
Design:
Retrospective cohort study.
Setting:
Not applicable.
Patient(S):
Endometriosis patients (aged 18-49 years) with (n = 124,530) or without (n = 37,106) a claim for endometriosis-related surgery were identified from the Truven Health MarketScan Commercial and Health and Productivity Management databases for 2006-2014.
Intervention(S):
Not applicable.
Main Outcome Measure(S):
Primary outcomes were healthcare utilization during 12-month pre- and post-index periods, annual direct (healthcare) and indirect (absenteeism and short- and long-term disability) costs during the 12-month post-index period (in 2014 US dollars). Indirect costs were assessed for patients with available productivity data.
Result(S):
Patients in the surgery cohort had significantly higher healthcare resource utilization during the post-index period and had mean annual total adjusted post-index direct costs approximately three times the costs among patients in the no-surgery cohort ($19,203 [SD $7,133] vs. $6,365 [SD $2,364]; average incremental annual direct cost = $12,838). The mean cost of surgery ($7,268 [SD $7,975]) was the single largest contributor to incremental annual direct cost. Mean estimated annual total indirect costs were $8,843 (surgery cohort) vs. $5,603 (no-surgery cohort); average incremental annual indirect cost = $3,240.
Conclusion(S):
Endometriosis patients who underwent surgery, compared with endometriosis patients who did not, incurred significantly higher direct costs due to healthcare utilization and indirect costs due to absenteeism or short-term disability. Regardless of the surgery type, the cost of index surgery contributed substantially to the total healthcare expenditure.
