Factors Associated with Time to Endometriosis Diagnosis in the United States

Background: We aimed to quantify the time to diagnosis among women with endometriosis in the United States (US) and to identify patient-and physician-related factors affecting diagnostic delay. Patients and Methods: An online cross-sectional survey was conducted from August 6, 2012, through November 14, 2012. Respondents aged 18-49 years who reported a physician's diagnosis/suspicion of endometriosis within the previous 10 years were included. Endometriosis-related symptoms and diagnostic history were captured and summarized. Univariate analyses identified factors associated with time from symptom onset to first consultation and from first consultation to diagnosis. Results: Of 638 respondents included, most (56%) reported seeking care for at least one of the following symptoms: menstrual pain (31.6%), nonmenstrual pain (27.3%), and pain during sex (7.5%). Most diagnoses (84%) were made by obstetricians/gynecologists; 49% of diagnoses were surgical versus 51% nonsurgical. Mean time from symptom onset to diagnosis was 4.4 years. Mean time to first consultation was shorter among women aged 40-49 years versus those aged <18 years (14.2 vs. 43.5 months; p < 0.0001) and those consulting for symptoms versus routine/other care (27.9, 24.9, and 28.4 months for menstrual pain, nonmenstrual pain, and pain during sex, respectively, vs. 61.4 months; all p < 0.01). Mean time from first consultation to diagnosis was shorter among women aged 40-49 years versus those aged < 18 years (12.4 vs. 34.5 months; p = 0.0009) and those diagnosed by obstetricians/gynecologists versus nonobstetricians/gynecologists (21.5 vs. 40.3 months; p = 0.041). Conclusions: Time to endometriosis diagnosis appears to have shortened in the US. Better patient and physician education regarding symptomatology may contribute to further gains.
