Community-based screening for obstetric fistula in Nigeria: a novel approach

Obstetric fistula continues to have devastating effects on the physical, social, and economic lives of thousands of women in many low-resource settings. Governments require credible estimates of the backlog of existing cases requiring care to effectively plan for the treatment of fistula cases. Our study aims to quantify the backlog of obstetric fistula cases within two states via community-based screenings and to assess the questions in the Demographic Health Survey (DHS) fistula module. The screening sites, all lower level health facilities, were selected based on their geographic coverage, prior relationships with the communities and availability of fistula surgery facilities in the state. This cross-sectional study included women who presented for fistula screenings at study facilities based on their perceived fistula-like symptoms. Research assistants administered the pre-screening questionnaire. Nurse-midwives then conducted a medical exam. Univariate and bivariate analyses are presented. A total of 268 women attended the screenings. Based on the pre-screening interview, the backlog of fistula cases reported was 75 (28% of women screened). The backlog identified after the medical exam was 26 fistula cases (29.5% of women screened) in Kebbi State sites and 12 cases in Cross River State sites (6.7%). Verification assessment showed that the DHS questionnaire had 92% sensitivity, 83% specificity with 47% positive predictive value and 98% negative predictive value for identifying women afflicted by fistula among women who came for the screenings. This methodology, involving effective, locally appropriate messaging and community outreach followed up with medical examination by nurse-midwives at lower level facilities, is challenging, but represents a promising approach to identify the backlog of women needing surgery and to link them with surgical facilities.
