Quantification of the impact of endometriosis symptoms on health-related quality of life and work productivity
Open accessAbstract
OBJECTIVE To quantify the impact of endometriosis-related symptoms on physical and mental health status, health-related quality of life (HRQoL), and work-related aspects (absenteeism, presenteeism, work productivity, activity impairment). DESIGN Cross-sectional quantitative study. SETTING Academic and research institution. PATIENT(S) Women (n=193) with self-reported surgically diagnosed endometriosis from the Endometriosis Patient Registry at Ponce School of Medicine and Health Sciences (PSMHS). INTERVENTION(S) Patients completed an anonymous questionnaire divided into three sections consisting of questions from the Patient Health Survey (SF-12®), the Endometriosis Health Profile (EHP-5), and the Work Productivity and Activity Impairment Survey (WPAI). MAIN OUTCOME MEASURE(S) Impact of endometriosis symptoms on physical and mental health status, health-related quality of life (HRQoL), absenteeism, presenteeism, work productivity and activity impairment was quantified. RESULTS Patients had SF-12 scores denoting significant disability in the phyisical and mental health components. They also reported an average of 7.41 hrs (approximately one working day) of work time loss during the week the symptoms are worse. In addition, WPAI scores show high impact on work-related domains: 13% of average loss in work time (absenteeism), 65% of their work was impaired (presenteeism), 64% loss in efficiency levels (work productivity loss), and 60% of daily activities perturbed (activity impairment). CONCLUSION Endometriosis symptoms such as chronic, incapacitating pelvic pain and infertility negatively and substantially impact the physical and mental health status, HRQoL, and productivity at work of patients with endometriosis.

Before this study, the effect of endometriosis symptoms on work productivity had not been measured with standardized instruments.
“One important aspect of QoL is work productivity; however, the impact of endometriosis symptoms on this particular area has not been quantified to date using standardized instruments.”

The week of the last menstrual period or when symptoms were worse is representative of the typical impact of endometriosis symptoms on work and daily activities.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-09-28, under version 3 of the claim definition (prompt extract-v3).
A second model labelled each claim on 2026-09-28 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
