Factors associated with loss to follow-up in women undergoing repair for obstetric fistula in Guinea

Travel barriers, unemployment, and external fixation predict loss to follow-up after surgical management of lower extremity fractures in Dar es Salaam, Tanzania

Objective:

Predict loss to follow-up in prospective clinical investigations of lower extremity fracture surgery.

Design:

Secondary analysis of 2 prospective clinical trials.

Setting:

National public orthopaedic and neurologic trauma tertiary referral hospital in Dar es Salaam, Tanzania, a low-income country in sub-Saharan Africa.

Patients/Participants:

Three hundred twenty-nine femoral shaft and 240 open tibial shaft fracture patients prospectively enrolled in prospective controlled trials of surgical fracture management by external fixation, plating, or intramedullary nailing between June 2015 and March 2017.

Intervention:

Telephone contact for failure to attend scheduled 1-year clinic visit.

Main Outcome Measurements:

Ascertainment of primary trial outcome at 1-year from surgery; post-hoc telephone questionnaire for reasons patient did not attend the 1-year clinic visit.

Results:

One hundred twenty-seven femur fracture (39%) and 68 open tibia fracture (28%) patients did not attend the 1-year clinic visit. Telephone contact significantly improved ascertainment of the primary study outcome by 20% between 6-month and 1-year clinic visits to 82% and 92% respectively at study completion. Multivariable analysis associated unemployment (OR = 2.5 [1.7–3.9], P < .001), treatment with an external fixator (OR = 1.7 [1.0–2.8], P = .033), and each additional 20 km between residence and clinic (OR = 1.03 [1.00–1.06], P = .047] with clinic nonattendance. One hundred eight (55%) nonattending patients completed the telephone questionnaire, reporting travel distance to the hospital (49%), and travel costs to the hospital (46%) as the most prevalent reasons for nonattendance. Sixty-five percent of patients with open tibia fractures cited relocation after surgery as a contributing factor.

Conclusions:

Relocation during recovery, travel distance, travel cost, unemployment, and use of an external fixator are associated with loss to clinical follow-up in prospective investigations of femur and open tibia fracture surgery in this population. Telephone contact is an effective means to assess outcome.

Research in Obstetric Fistula: Addressing Gaps and Unmet Needs

Although obstetric fistula has likely plagued women since the beginning of time, very little research proportionally exists. This article summarizes the most substantial research on the topic and delineates research gaps and future needs. Existing research demonstrates that access to care is the underlying cause of obstetric fistula and that the first attempt at closure holds the highest chance at success, ranging between 84% and 94%. For simple cases, 10 days of a catheter is sufficient, although what constitutes as simple is unclear. Circumferential fistulas are at high risk for ongoing urethral continence. Psychosocial programs are helpful for all women, but those who are "dry" tend to reintegrate into society, whereas those still leaking need additional support. Prenatal care and scheduled cesarean delivery are recommended to avoid another fistula. Gaps in research include accurate prevalence and incidence, interventions to improve access to care, surgical technique, especially for complex cases, and ways to prevent ongoing incontinence, among many others. In all areas, more rigorous research is needed.

Fistula recurrence, pregnancy, and childbirth following successful closure of female genital fistula in Guinea: a longitudinal study

Background

Female genital fistula is a devastating maternal complication of delivery in developing countries. We sought to analyse the incidence and proportion of fistula recurrence, residual urinary incontinence, and pregnancy after successful fistula closure in Guinea, and describe the delivery-associated maternal and child health outcomes.

Methods

We did a longitudinal study in women discharged with a closed fistula from three repair hospitals supported by EngenderHealth in Guinea. We recruited women retrospectively (via medical record review) and prospectively at hospital discharge. We used Kaplan-Meier methods to analyse the cumulative incidence, incidence proportion, and incidence ratio of fistula recurrence, associated outcomes, and pregnancy after successful fistula closure. The primary outcome was recurrence of fistula following discharge from repair hospital in all eligible women who consented to inclusion and could provide follow-up data.

Findings

481 women eligible for analysis were identified retrospectively (from Jan 1, 2012, to Dec 31, 2014; 348 women) or prospectively (Jan 1 to June 20, 2015; 133 women), and followed up until June 30, 2016. Median follow-up was 28·0 months (IQR 14·6–36·6). 73 recurrent fistulas occurred, corresponding to a cumulative incidence of 71 per 1000 person-years (95% CI 56·5–89·3) and an incidence proportion of 18·4% (14·8–22·8). In 447 women who were continent at hospital discharge, we recorded 24 cases of post-repair residual urinary incontinence, equivalent to a cumulative incidence of 23·1 per 1000 person-years (14·0–36·2), and corresponding to 10·3% (5·2–19·6). In 305 women at risk of pregnancy, the cumulative incidence of pregnancy was 106·0 per 1000 person-years, corresponding to 28·4% (22·8–35·0) of these women. Of 50 women who had delivered by the time of follow-up, only nine delivered by elective caesarean section. There were 12 stillbirths, seven delivery-related fistula recurrences, and one maternal death.

Interpretation

Recurrence of female genital fistula and adverse pregnancy-related maternal and child health outcomes were frequent in women after fistula repair in Guinea. Interventions are needed to safeguard the health of women after fistula repair.

Pregnancy and childbirth after repair of obstetric fistula in sub-Saharan Africa: Scoping Review

OBJECTIVE

To synthesise the evidence on pregnancy and childbirth after repair of obstetric fistula in sub-Saharan Africa and to identify the existing knowledge gaps.

METHODS

A scoping review of studies reporting on pregnancy and childbirth in women who underwent repair for obstetric fistula in sub-Saharan Africa was conducted. We searched relevant articles published between 1 January 1970 and 31 March 2016, without methodological or language restrictions, in electronic databases, general Internet sources and grey literature.

RESULTS

A total of 16 studies were included in the narrative synthesis. The findings indicate that many women in sub-Saharan Africa still desire to become pregnant after the repair of their obstetric fistula. The overall proportion of pregnancies after repair estimated in 11 studies was 17.4% (ranging from 2.5% to 40%). Among the 459 deliveries for which the mode of delivery was reported, 208 women (45.3%) delivered by elective caesarean section (CS), 176 women (38.4%) by emergency CS and 75 women (16.3%) by vaginal delivery. Recurrence of fistula was a common maternal complication in included studies while abortions/miscarriage, stillbirths and neonatal deaths were frequent foetal consequences. Vaginal delivery and emergency C-section were associated with increased risk of stillbirth, recurrence of the fistula or even maternal death.

CONCLUSION

Women who get pregnant after repair of obstetric fistula carry a high risk for pregnancy complications. However, the current evidence does not provide precise estimates of the incidence of pregnancy and pregnancy outcomes post-repair. Therefore, studies clearly assessing these outcomes with the appropriate study designs are needed.
