Predicting women at risk for developing obstetric fistula: a fistula index? An observational study comparison of two cohorts

Development and Pilot Test of a Group Cognitive Behavioral Intervention for Women Recovering From Fistula Repair Surgery in Ethiopia

Obstetric fistula is a serious complication that affects thousands of women in low-income countries. Women who suffer from obstetric fistulae are at risk of developing mental health problems, but to date most interventions have focused on repairing the physical consequences of fistulae through surgery. The goal of the current study is to develop an evidence-based intervention targeting symptoms of depression, anxiety, and trauma in women recovering from fistula repair surgery. First, hospital staff and patients awaiting surgery at a fistula hospital in Ethiopia participated in qualitative interviews to provide information on the mental health needs of women with fistulae, how the hospital tends to these women's psychological needs, and the training needs of staff members. Data from these interviews were used to develop the COFFEE intervention (CBT with Obstetric Fistula for Education and Empowerment). COFFEE is a modular, group intervention that teaches psycho-education, behavioral activation, relaxation, problem solving, cognitive restructuring, and includes a trauma narrative. Patients then participated in an open trial of the COFFEE intervention at the University of Gondar Hospital. Five separate groups were conducted with 24 women who were enrolled post-fistula repair surgery. Women completed pre-treatment self-report questionnaires, participated in group sessions conducted by nurses (with 8 sessions delivered across 10–14 days), and were assessed post-treatment and at 3-month follow-up. Results indicate a significant reduction on depression and anxiety symptoms scores across the three time points [F_{(2, 40)} = 68.45, p < 0.001 partial η² = 0.774]. Additionally, there was a significant decrease in traumatic stress scores from baseline to post-treatment [F_{(1.10, 21.98)} = 100.51, p < 0.001 partial η² = 0.834]. Feedback forms completed by nurses and patients suggest the intervention was well-received. Results of this open-trial suggest the COFFEE intervention is feasible, acceptable, and clinically beneficial to treat symptoms of depression, anxiety, and traumatic stress in women post-fistula repair surgery in a hospital setting.

Obstetric and Gynecologic Genitourinary Fistulas

Urinary incontinence shortly after childbirth or gynecologic surgery can be the result of obstetric or iatrogenic fistula formation. This can be a confusing and challenging diagnosis for medical providers. While the number of iatrogenic fistula cases is rising worldwide, obstetric fistulas are an issue uniquely particular to resource poor settings. Appropriate treatment of genitourinary fistulas spans beyond surgical intervention of leakage, and includes re-integration into the community, widespread education and counseling, and battling social stigma and cultural biases. Current and future research must focus on rigorous, unified efforts to set evidence-based practices to help the millions of women affected.

Healthcare Access as a Risk-Marker for Obstetric Vesicovaginal Fistula in Malawi

OBJECTIVES

To determine the association between access to health care among pregnant women in Malawi and occurrence of obstetric vesicovaginal fistula (VVF).

METHODS

This was a case-control study using data obtained from patients' records documented by the 'Fistula Care Center-Bwaila Hospital' in Malawi. Socio-demographic characteristics of women with VVF (study arm, n=1046) and perineal tear (control arm, n=37) were examined. A composite variable called "Malawi Healthcare Access Index" (MHAI) was created through summation of scores related to three factors of access to care: (1) walking distance to closest health center; (2) presence of trained provider at delivery; and (3) receipt of antenatal care. Binomial logistic regression models were built to determine the association between the MHAI and presence of VVF.

RESULTS

Obstetric VVF was more common in women from rural areas, mothers delivering at extremes of age, those with less education, and patients with long labor (>12 hours). In adjusted models, women with "insufficient" health access based on the MHAI were at greater risk (OR = 2.64, 95%CI = 1.07 - 6.03) of obstetric VVF than women with "sufficient" score on the MHAI.

CONCLUSION AND GLOBAL HEALTH IMPLICATIONS

Inadequate access to essential obstetric care increases the risk of VVF.

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.

Predictors of Recurrence and Successful Treatment Following Obstetric Fistula Surgery

OBJECTIVE

To determine factors contributing to recurrence and successful treatment of obstetric fistula (OF).

MATERIALS AND METHODS

Data were collected from OF patients in Saint Luc Hospital Kisantu (DR of Congo) between 2007 and 2013. Patients underwent surgical treatment and were evaluated after a follow-up period of 3 months. Successful treatment was defined as no or dry pads whereas recurrence was defined as the persisting need for wearing incontinence pads immediately after the surgery or after a period of dryness. Fistula classification was done according to Waaldijk. Univariate and multivariate analyses were performed using logistic regression, corrected for preoperative and intraoperative OF characteristics.

RESULTS

Median age of 166 OF patients was 29.11 ± 9. 6 years (range 5-61). The majority of OF was type I (57.2%) followed by type III (20.5 %). There were 20.5% who showed vaginal fibrosis during surgical treatment. The most common location of fistula was pericervical (39.8%). The global recurrence rate at 3 months was 28.3%, with type IIBb (100%) as most the common recurring, followed by IIAb (66.67%) and IIAa (41.18%). There were 71.7%, 15.7%, 12%, and 0.6% patients who were considered completely cured, partially cured (downstaged), persistent, and upstaged, respectively. OF patients with fibrosis were 68% less likely (odds ratio 0.32, 95% confidence interval 0.14-0.73; P = .0065) to be dry in comparison to those without fibrosis. Patients with urethral fistula were 73% less likely (odds ratio 0.27, 95% confidence interval 0.11-0.63; P = .0024) to be dry compared to other locations.

CONCLUSION

This study showed that fibrosis and urethral location are independent risk factors for fistula recurrence or persistence following surgical fistula repair.

The changing face of obstetric fistula surgery in Ethiopia

OBJECTIVE

To examine the incidence and type of obstetric fistula presenting to Hamlin Fistula Ethiopia over a 4-year period.

STUDY DESIGN

This is a 4-year retrospective survey of obstetric fistula treated at three Hamlin Fistula Hospitals in Ethiopia, where approximately half of all women in the country are treated. The operation logbook was reviewed to identify all new cases of obstetric fistula presenting from 2011 to 2015. New cases of urinary fistula were classified by fistula type (high or low), age, and parity of the woman.

RESULTS

In total, 2,593 new cases of urinary fistulae were identified in the study period. The number of new cases fell by 20% per year over the 4 years (P<0.001). A total of 1,845 cases (71.1%) were low (ischemic) fistulae, and 804 cases (43.6%) of these had an extreme form of low circumferential fistula. A total of 638 (24.6%) women had a high bladder fistula, which predominantly occurs following surgery, specifically cesarean section or emergency hysterectomy, and 110 (4.2%) women had a ureteric fistula. The incidence of high fistulae increased over the study period from 26.9% to 36.2% (P<0.001). A greater proportion of multiparous women had a high bladder fistula (70.3%) compared with primigravid women (29.7%) (P<0.001). Conversely, a greater proportion of primiparous women experienced a low circumferential fistulae (68.6%) compared with multiparous women (31.4%) (P<0.001).

CONCLUSION

There appears to be a decline in the number of Ethiopian women being treated for new obstetric urinary fistulae. However, the type of fistula being presented for treatment is changing, with a rise in high fistulae that very likely occurred following cesarean section and a decline in the classic low fistulae that arise following obstructed childbirth.

Risk factors for vaginal fistula symptoms in Sub-Saharan Africa: a pooled analysis of national household survey data

BACKGROUND

Vaginal fistula (VF) is one of the most severe maternal morbidities with the immediate consequence of chronic urinary and/or fecal incontinence. The epidemiological evidence regarding risk factors for VF is dominated by facility-based studies. Our aim is to estimate the effect size of selected risk factors for VF using population-based survey data.

METHODS

We pooled all available Demographic and Health Surveys and Multiple Indicators Cluster Surveys carried out in sub-Saharan Africa that collected information on VF symptoms. Bayesian matched logistic regression models that accounted for the imperfect sensitivity and specificity of self-reports of VF symptoms were used for effect size estimation.

RESULTS

Up to 27 surveys were pooled, including responses from 332,889 women. Being able to read decreased the odds of VF by 13% (95% Credible Intervals (CrI): 1% to 23%), while higher odds of VF symptoms were observed for women of short stature (<150 cm) (Odds Ratio (OR) = 1.31; 95% CrI: 1.02-1.68), those that had experienced intimate partner sexual violence (OR = 2.13; 95% CrI: 1.60-2.86), those that reported sexual debut before the age of 14 (OR = 1.41; 95% CrI: 1.16-1.71), and those that reported a first birth before the age of 14 (OR = 1.39; 95% CrI: 1.04-1.82). The effect of post-primary education, female genital mutilation, and having problems obtaining permission to seek health care were not statistically significant.

CONCLUSIONS

Increasing literacy, delaying age at first sex/birth, and preventing sexual violence could contribute to the elimination of obstetric fistula. Concomitant improvements in access to quality sexual and reproductive healthcare are, however, required to end fistula in sub-Saharan Africa.

Prevention of pelvic floor disorders: international urogynecological association research and development committee opinion

INTRODUCTION AND HYPOTHESIS

Pelvic floor disorders (PFD), including urinary incontinence, anal incontinence, and pelvic organ prolapse, are common and have a negative effect on the quality of life of women. Treatment is associated with morbidity and may not be totally satisfactory. Prevention of PFDs, when possible, should be a primary goal. The purpose of this paper is to summarise the current literature and give an evidence-based review of the prevention of PFDs METHODS: A working subcommittee from the International Urogynecological Association (IUGA) Research and Development (R&D) Committee was formed. An initial document addressing the prevention of PFDs was drafted, based on a review of the English-language literature. After evaluation by the entire IUGA R&D Committee, revisions were made. The final document represents the IUGA R&D Committee Opinion on the prevention of PFDs.

RESULTS

This R&D Committee Opinion reviews the literature on the prevention of PFDs and summarises the findings with evidence-based recommendations.

CONCLUSIONS

Pelvic floor disorders have a long latency, and may go through periods of remission, thus making causality difficult to confirm. Nevertheless, prevention strategies targeting modifiable risk factors should be incorporated into clinical practice before the absence of symptomatology.

Urogenital fistula reviewed: a marker of severe maternal morbidity and an indicator of the quality of maternal healthcare delivery

BACKGROUND

While obstetric fistula has been recognized as a major maternal morbidity since the 1980s, it has become an indicator of access to and quality of women' s health care.

FINDINGS

Obstetric fistula still exists in low-income countries (LIC) because health care systems fail to provide adequate family planning, skilled birth attendance, basic and emergency obstetric care, and affordable treatment of fistula, while concurrently lacking social networks to serve as safety nets for affected girls and women [WHO, 2007].

CONCLUSION

This review explores the most recent published experience with respect to the definition of fistula, its diagnosis, treatment, and management, and further steps for prevention of fistula on a global scale.

Risk factors for obstetric fistula in Western Uganda: a case control study

INTRODUCTION

Two million women worldwide are living with genital fistula with an annual incidence of 50,000-100,000 women. Risk factors for obstetric fistula are context bound. Studies from other countries show variation in the risk factors for obstetric fistula. This study was conducted to identify risk factors for obstetric fistula in western Ugandan context.

METHODS

A case control study comparing background factors of women with obstetric fistula (cases) and women without fistula (controls) was conducted in western Uganda. Data was collected using face-to-face interviews. Univariate, bivariate and multivariate analysis was conducted using Stata 12.

RESULTS

Altogether, 420 respondents (140 cases and 280 controls) participated in the study. Duration of labour was used to form the product terms when assessing for interaction and confounding since it was one the most significant factors at bivariate level with a narrow confidence interval and was hence considered the main predictor. After adjusting for interaction and confounding, significant risk factors associated with development of obstetric fistula in western Uganda were: Caesarean section (adjusted odds ratio [AOR] = 13.30, 95% CI = 6.74-26.39), respondent height of 150 cm or less (AOR = 2.63, 95% CI = 1.35-5.26), baby weight of 3.5 kg or more (AOR = 1.52, 95% CI = 1.15-1.99), prolonged labour (AOR = 1.06, 95% CI = 1.04-1.08. A quarter of the fistulas had resulted from iatrogenic complication during caesarean section. Compared to no education, post primary level of education was protective against obstetric fistula (AOR = 0.31, 95% CI = 0.13-0.72) and there was no difference between respondents without education and those with primary level education.

CONCLUSIONS

Surgeons contribute to a big proportion (25%) of fistula cases hence caesarean section being a risk factor in this region. Other risk factors include; prolonged labour, weight of the baby of 3.5 kg or more, respondent height of 150 cm or less (short stature), and low or no education are risk factors for obstetric fistula in western Ugandan.
