Quality of Life Assessment Using EuroQOL EQ-5D Questionnaire in Patients with Deep Infiltrating Endometriosis : The Relation with Symptoms and Locations

Abstract EN

The objective of this study was to evaluate the quality of life (QOL) of patients with deep infiltrating endometriosis (DIE) using EuroQOL (EQ-5D) and its correlation with symptoms and locations of endometriotic lesions.

One hundred and fifty-nine patients referred for DIE from January 2011 to April 2011 were prospectively invited to complete questionnaires evaluating symptoms associated with endometriosis as well as the EQ-5D questionnaire and health state.

Patients also had locations of DIE evaluated by clinical examination and magnetic resonance imaging (MRI).

All 159 patients completed the questionnaires.

Item response rate was 91.1%.

The most intense symptoms were dysmenorrhea (7.1/10), painful defecation (6.3/10), and fatigue (6.0/10).

Mean (SD) scores were 77 (14) for the EQ-5D questionnaire and 63.4 (21) for the health state.

A relation was observed between the EQ-5D questionnaire and the presence of dysmenorrhea, dyspareunia, cyclic pelvic pain, painful defecation, and diarrhea or constipation.

Vaginal and rectal infiltrations were significantly associated with altered EQ-5D and health state scores.

The EQ-5D questionnaire is easy to complete and well related to symptoms of DIE.

Rectal and vaginal infiltrations were found to be determinant factors of altered QOL by the EQ-5D questionnaire and health state.
