Fistula Clinical Trial - Recurrence & Pregnancy Post-repair of Obstetric

Status Completed

Clinical Trial Summary

Obstetric fistula, also called vaginal fistula, is a serious medical condition which affects women in low income countries. Despite the strengthening of research on fistula, there is little data on the follow-up after fistula repair.

The objective of this study is to analyse the factors associated with the recurrence of fistula and the outcomes of pregnancy following fistula repair in Guinea. It will target women who got a closed fistula at discharge after repair in 2012/2015 at three fistula repair sites supported by the Fistula Care Project in Guinea (Kissidougou Prefectoral Hospital, Labé Regional Hospital and Jean Paul II Hospital of Conakry).

The outcomes of interest are fistula recurrence and pregnancy. The predictors of interest will include patient characteristics, fistula characteristics, the context of repair and the context of reintegration.

Participants giving an informed consent after a home visit by the Fistula Counsellors who managed women during surgery will be interview at enrolment and every six month from inclusion. The study duration is estimated at 48 months (January 2012 to March 2016) including the retrospective part.

A sample size of 364 women will estimate the recurrence of fistula with a plus/minus 2% margin of error (width of confidence interval is 4%) and 95% confidence interval and is sufficient to estimate the rate of pregnancy with a two-sided 95% confidence interval and 10% precision.

The cumulative incidence rate of fistula recurrence will be calculated using Kaplan-Meier methods and the risk factor analysis will be performed using adjusted cox regression.

For the outcomes of pregnancy, Pearson's Chi Square (χ2) will be used to compare proportions of pregnancy outcomes between potential predictors and logistic regression models will be used and associations will be reported as risk ratios with 95% confidence intervals.

Analysis will be done using STATA version 13 (STATA Corporation, College Station, TX, USA) with a level of significance set at P<0.05.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
