Abstract: Objective: To evaluate the burden of endometriosis-associated pelvic pain (EAPP) on health-related quality of life (HRQoL) among women living in similar socio-economic conditions.
Data Sources: Searches were performed in PubMed and Embase on September 26, 2022. The review was performed in conformity with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis protocol (PRISMA-P) and was registered on PROSPERO (ID: CRD42023370363).
Methods of Study Selection: Due to the high volume of eligible publications following initial review, inclusion criteria were restricted to studies undertaken in France, Germany, Italy, Spain, the United Kingdom, and the United States. This restriction was applied before screening as these countries have broad social and economic similarities, and previous studies in the literature suggest pain reporting and experience are influenced by numerous socio-cultural factors. Eligible studies were those published between 2013 and 2022 and include a sample size of ≥50 participants. The search strategy identified all relevant publications relating to the burden of illness due to EAPP. A variety of terms are used in the literature to describe pain associated with endometriosis, and this was considered in the design of the search strategy and screening procedure.
Tabulation, Integration, and Results: The database searches resulted in a total of 6139 records. After removal of duplicates, 3855 records were assessed further. A total of 27 publications were identified as eligible. Fourteen (52%) were from Italy, 5 (19%) were multinational studies, 4 (15%) were from the United States, 3 (11%) were from Spain, and 1 (4%) was from Germany. Most studies were cross-sectional (n = 15; 56%); 7 (26%) were case-control studies; 3 (11%) were cohort studies; and 2 (7%) were longitudinal studies. These publications collectively highlighted an association between EAPP and reduced HRQoL. Several studies showed that EAPP was associated with lower HRQoL when compared with endometriosis without pain and potentially with chronic pelvic pain caused by other conditions, although the evidence is limited in this case. Moreover, the studies reported detrimental effects on general HRQoL, mental health functioning, and sexual functioning, culminating in reduced work productivity and difficulties in performing everyday activities. The associations were generally similar across study populations, including adolescents, as well as younger and older women. Results were consistent across the range of different patient-reported outcome tools used to assess HRQoL.
Conclusion: The existing literature suggests that, among women in selected European countries and the United States, EAPP is associated with reduced HRQoL, including impaired mental and sexual functioning, as well as reduced work performance and productivity; each of which may contribute to the societal burden of endometriosis.
