Objective: To comprehensively review and evaluate the direct costs of endometriosis.
Design and setting: We systematically reviewed studies published since 1990, and conducted an analysis of publicly available national databases (Healthcare Cost and Utilization Project and National Ambulatory Medical Care Survey/National Hospital Ambulatory Medical Care Survey) in the United States. We assessed: [1] the overall economic impact of endometriosis; [2] the direct costs associated with specific treatments; and [3] the indirect costs of endometriosis associated with reduced work productivity.
Results: Of 13 published studies meeting inclusion criteria, 11 (85%) addressed direct costs, a few studies addressed outpatient costs or indirect costs, and no study quantified the economic impact among adolescents. Direct endometriosis-related costs were considerable and appeared driven by hospitalizations. Our database analysis found: [1] as endometriosis-related hospital length of stay steadily declined from 1993 to 2002, per-patient cost increased 61%; [2] adolescents (aged 10-17 years) had endometriosis-related hospitalizations; [3] approximately 50% of >600,000 endometriosis-related ambulatory patient visits involved specialist care; and [4] females 23 years old or younger constituted >20% of endometriosis-related outpatient visits.
Conclusions: Health economic information for endometriosis is scarce, limiting our understanding of its overall economic impact. Nevertheless, the literature and other available data suggest that endometriosis places a considerable burden on patients and society.
