Prevalence of obstetric fistula: a population-based study in rural Pakistan

Objective To estimate the prevalence of obstetric fistula, its duration and impact on women's daily life using robust data collection methods in a population-based sample in rural Pakistan. Design A population-based, cross-sectional study. Setting A rural community in Sindh Province, Pakistan. Population Randomly selected women aged 15years or older. Methods A multistage random sampling strategy was used to recruit the women. Lady Health Workers interviewed women in their own homes using a structured questionnaire to obtain symptom data. Women with symptoms of incontinence were then examined by female gynaecologists in their local health facilities to confirm obstetric fistula. Main outcome measure Obstetric fistula confirmed by gynaecological examination. Results Among the 5064 women interviewed (96% response rate), 20 women with obstetric fistula were identified, showing a prevalence of 0.39% of all women (95% confidence interval [95% CI] 0.22-0.57%) and 0.45% of parous women (95% CI 0.25-0.65%). Significantly more of the women with obstetric fistula compared with parous women without fistula were primiparae and aged <20years. Of the women with obstetric fistula, 40% had had this for >5years and 90% reported a major impact on their lives, yet only four had consulted a doctor, three of whom had failed repairs. Conclusions The prevalence of obstetric fistula is high in rural Pakistan. Appropriate provision is needed for fistula repair to reduce the burden of the condition. Alongside this, the improvement of maternity care services is urgently needed to prevent its continued occurrence.
