We previously reported high inter- and intra-surgeon agreement for endometriosis diagnosis in the Endometriosis, Natural History, Diagnosis, and Outcomes (ENDO) Study.<\/jats:p>\n <\/jats:sec>\n \n STUDY DESIGN, SIZE, DURATION<\/jats:title>\n In this validation study, participants (n\u2009=\u2009412) of the Utah operative cohort of the ENDO Study (2007\u20132009) were linked to medical records from the Utah Population Database (UPDB) to compare endometriosis diagnoses from each source. The UPDB is a unique database containing linked data on over 11 million individuals, including statewide ambulatory and inpatient records, state vital records, and University of Utah Health and Intermountain Healthcare electronic healthcare records, capturing most Utah residents.<\/jats:p>\n <\/jats:sec>\n \n PARTICIPANTS\/MATERIALS, SETTING, METHODS<\/jats:title>\n The ENDO operative cohort consisted of individuals aged 18\u201344\u2009years with no prior endometriosis diagnosis who underwent gynecologic laparoscopy or laparotomy for a variety of surgical indications. In total, 173 women were diagnosed with endometriosis based on surgical visualization of disease, 35% with superficial endometriosis, 9% with ovarian endometriomas, and 14% with deep infiltrating endometriosis. Contemporary administrative health data from the UPDB included ICD diagnostic codes from Utah Department of Health in-patient and ambulatory surgery records and University of Utah and Intermountain Health electronic health records.<\/jats:p>\n <\/jats:sec>\n \n MAIN RESULTS AND THE ROLE OF CHANCE<\/jats:title>\n For endometriosis diagnosis, we found relatively high sensitivity (0.88) and specificity (0.87) and substantial agreement (Kappa [\u039a]\u2009=\u20090.74). We found similarly high sensitivity, specificity, and agreement for superficial endometriosis (n\u2009=\u2009143, 0.86, 0.83, \u039a\u2009\u2009=\u20090.65) and ovarian endometriomas (n\u2009=\u200938, 0.82, 0.92, \u039a\u2009\u2009=\u20090.58). However, deep infiltrating endometriosis (n\u2009=\u200958) had lower sensitivity (0.12) and agreement (\u039a\u2009\u2009=\u20090.17), with high specificity (0.99).<\/jats:p>\n <\/jats:sec>\n \n LIMITATIONS, REASONS FOR CAUTION<\/jats:title>\n Medication prescription data and unstructured data, such as clinical notes, were not included in the UPDB data used for this study. These additional data types could aid in detection of endometriosis. Most participants were white or Asian with Hispanic ethnicity reported 11% of the time, which may limit generalizability to some US states. Additionally, given that participants whose administrative health records we utilized were also part of the ENDO Study, the surgeons may have been more vigilant in diagnostic coding due to the operative forms they completed for the ENDO Study, which may have led to increased validity. However, the codes compared in the UPDB would have been entered by medical coders as part of standard clinical practice.<\/jats:p>\n <\/jats:sec>\n \n WIDER IMPLICATIONS OF THE FINDINGS<\/jats:title>\n We observed substantial agreement between administrative health data and surgically confirmed endometriosis diagnoses overall, and for superficial and ovarian endometrioma subtypes. These findings may provide reassurance to researchers using administrative healthcare records to assess risk factors and long-term health outcomes of endometriosis. Our findings corroborate prior research that demonstrates high specificity but low sensitivity for deep infiltrating endometriosis, indicating deep infiltrating endometriosis is not reliably annotated in administrative healthcare data. This suggests that medical record-based deep infiltrating endometriosis diagnoses may be suitable for etiologic studies but not for surveillance or detection studies.<\/jats:p>\n <\/jats:sec>\n \n STUDY FUNDING\/COMPETING INTEREST(S)<\/jats:title>\n The original ENDO Study was funded by the Intramural Research Program, Eunice Kennedy Shriver National Institute of Child Health and Human Development, National Institutes of Health (contracts NO1-DK-6-3428; NO1-DK-6-3427; 10001406-02).
