Hospital care of endometriosis in Spain: a retrospective multicenter analysis of patient characteristics and costs.

ABSTRACT

BACKGROUND: Despite the potential serious outcomes associated with endometriosis, few data is available describing the real clinical practice and costs. The aim of this study was to evaluate the characteristics of patients diagnosed with endometriosis in Spain, to measure incidences within the hospital setting and the associated medical costs.Methods: Admission records of patients with endometriosis registered between 2009 and 2018 were obtained from a Spanish hospital discharge database and analyzed in a retrospective multicenter study. RESULTS: Data corresponded primarily to inpatient admissions, with a median length of stay of 3 days. Length of stay correlated with patients' age. Admissions were mainly associated with surgical procedures, namely local excision or destruction of lesions. The majority of secondary diagnoses registered corresponded to inflammatory disease of female pelvic organs; 9.2% of patients presented neoplasms of uterus and only 0.9% registered ovarian neoplasms. Mean admission cost was €3566 over the study period. CONCLUSIONS: The majority of admissions reviewed in this study corresponded to the removal of ovarian lesions, although data suggested a decrease in the number of cases that were treated as hospital inpatient admissions over the study period. Older patients, surgical procedures, and lengthier admissions were associated with higher medical costs.
