Breakdown of simple female genital fistula repair after 7 day versus 14 day postoperative bladder catheterisation: a randomised, controlled, open-label, non-inferiority trial

BACKGROUND

Duration of bladder catheterisation after female genital fistula repair varies widely. We aimed to establish whether 7 day bladder catheterisation was non-inferior to 14 days in terms of incidence of fistula repair breakdown in women with simple fistula.

METHODS

In this randomised, controlled, open-label, non-inferiority trial, we enrolled patients at eight hospitals in the Democratic Republic of the Congo, Ethiopia, Guinea, Kenya, Niger, Nigeria, Sierra Leone, and Uganda. Consenting patients were eligible if they had a simple fistula that was closed after surgery and remained closed 7 days after surgery, understood study procedures and requirements, and agreed to return for follow-up 3 months after surgery. We excluded women if their fistula was not simple or was radiation-induced, associated with cancer, or due to lymphogranuloma venereum; if they were pregnant; or if they had multiple fistula. A research assistant at each site randomly allocated participants 1:1 (randomly varying block sizes of 4-6; stratified by country) to 7 day or 14 day bladder catheterisation (via a random allocation sequence computer generated centrally by WHO). Outcome assessors were not masked to treatment assignment. The primary outcome was fistula repair breakdown, on the basis of dye test results, any time between 8 days after catheter removal and 3 months after surgery. The non-inferiority margin was 10%, assessed in the per-protocol population. This trial is registered with ClinicalTrials.gov, number NCT01428830.

FINDINGS

We randomly allocated 524 participants between March 7, 2012, and May 6, 2013; 261 in the 7 day group and 263 in the 14 day group. In the per-protocol analysis, ten (4%) of 250 patients had repair breakdown in the 7 day group (95% CI 2-8) compared with eight (3%) of 251 (2-6) in the 14 day group (risk difference 0·8% [95% CI -2·8 to 4·5]), meeting the criteria for non-inferiority.

INTERPRETATION

7 day bladder catheterisation after repair of simple fistula is non-inferior to 14 day catheterisation and could be used for management of women after repair of simple fistula with no evidence of a significantly increased risk of repair breakdown, urinary retention, or residual incontinence up to 3 months after surgery.

Mortality risk associated with surgical treatment of female genital fistula

OBJECTIVE

To describe the mortality risk associated with surgical treatment of female genital fistula and the contributory and contextual factors.

METHODS

In a descriptive study, confidential inquiries and clinical audits were conducted at 14 fistula repair sites in seven resource-poor countries between January 2005 and March 2013. Data collection included interviews with key personnel involved in the clinical management of the deceased, and a review of hospital records and patient files following an audit protocol.

RESULTS

Overall, 26060 fistula repairs were performed at 44 sites located in 13 countries; 30 deaths were reported in this period. Twenty-one deaths were attributable to surgery, yielding a case fatality of 0.08 per 100 procedures. The cause of death in nearly half of the cases was various manifestations of sepsis and inflammation.

CONCLUSION

The case fatality rate for fistula repair surgery in resource-poor countries was in the same range as that for comparable gynecologic operations in high-resource settings. Clinical and systemic issues to be addressed to reduce the case fatality rate include improvement of perioperative care and follow-up, assuring prudent referral or deferral of difficult cases, and maintaining better records.

Assessing the quality of record keeping for cesarean deliveries: results from a multicenter retrospective record review in five low-income countries

Background

Reliable, timely information is the foundation of decision making for functioning health systems; the quality of decision making rests on quality data. Routine monitoring, reporting, and review of cesarean section (CS) indications, decision-to-delivery intervals, and partograph use are important elements of quality improvement for maternity services.

Methods

In 2009 and 2010, a sample of CS records from calendar year 2008 was reviewed at nine facilities in Bangladesh, Guinea, Mali, Niger, and Uganda. Data from patient records and hospital registers were collected on key aspects of care such as timing of key events, indications, partograph use, maternal and fetal outcomes. Qualitative interviews were conducted with key informants at all study sites to provide contextual background about CS services and record keeping practices.

Results

A total of 2,941 records were reviewed and 57 key informant interviews were conducted. Patient record-keeping systems were of varying quality across study sites: at five sites, more than 20% of records could not be located. Across all sites, patient files were missing key aspects of CS care: timing of key events (e.g., examination, decision to perform CS), administration of prophylactic antibiotics, maternal complications, and maternal and fetal outcomes. Rates of partograph use were low at six sites: 0 to 23.9% of patient files at these sites had a completed partograph on file, and among those found, 2.1% to 65.1% were completed correctly. Information on fetal outcomes was missing in up to 40% of patient files.

Conclusions

Deficits in the quality of CS patient records across a broad range of health facilities in low-resource settings in four sub-Saharan Africa countries and Bangladesh indicate an urgent need to improve record keeping.

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

BACKGROUND

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.

METHODS

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.

RESULTS

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.

CONCLUSIONS

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.

Profiles and experiences of women undergoing genital fistula repair: findings from five countries

This article presents data from 1354 women from five countries who participated in a prospective cohort study conducted between 2007 and 2010. Women undergoing surgery for fistula repair were interviewed at the time of admission, discharge, and at a 3-month follow-up visit. While women's experiences differed across countries, a similar picture emerges across countries: women married young, most were married at the time of admission, had little education, and for many, the fistula occurred after the first pregnancy. Median age at the time of fistula occurrence was 20.0 years (interquartile range 17.3–26.8). Half of the women attended some antenatal care (ANC); among those who attended ANC, less than 50% recalled being told about signs of pregnancy complications. At follow-up, most women (even those who were not dry) reported improvements in many aspects of social life, however, reported improvements varied by repair outcome. Prevention and treatment programmes need to recognise the supportive role that husbands, partners, and families play as women prepare for safe delivery. Effective treatment and support programmes are needed for women who remain incontinent after surgery.

Non-inferiority of short-term urethral catheterization following fistula repair surgery: study protocol for a randomized controlled trial

Background

A vaginal fistula is a devastating condition, affecting an estimated 2 million girls and women across Africa and Asia. There are numerous challenges associated with providing fistula repair services in developing countries, including limited availability of operating rooms, equipment, surgeons with specialized skills, and funding from local or international donors to support surgeries and subsequent post-operative care. Finding ways of providing services in a more efficient and cost-effective manner, without compromising surgical outcomes and the overall health of the patient, is paramount. Shortening the duration of urethral catheterization following fistula repair surgery would increase treatment capacity, lower costs of services, and potentially lower risk of healthcare-associated infections among fistula patients. There is a lack of empirical evidence supporting any particular length of time for urethral catheterization following fistula repair surgery. This study will examine whether short-term (7 day) urethral catheterization is not worse by more than a minimal relevant difference to longer-term (14 day) urethral catheterization in terms of incidence of fistula repair breakdown among women with simple fistula presenting at study sites for fistula repair service.

Methods/Design

This study is a facility-based, multicenter, non-inferiority randomized controlled trial (RCT) comparing the new proposed short-term (7 day) urethral catheterization to longer-term (14 day) urethral catheterization in terms of predicting fistula repair breakdown. The primary outcome is fistula repair breakdown up to three months following fistula repair surgery as assessed by a urinary dye test. Secondary outcomes will include repair breakdown one week following catheter removal, intermittent catheterization due to urinary retention and the occurrence of septic or febrile episodes, prolonged hospitalization for medical reasons, catheter blockage, and self-reported residual incontinence. This trial will be conducted among 512 women with simple fistula presenting at 8 study sites for fistula repair surgery over the course of 24 months at each site.

Discussion

If no major safety issues are identified, the data from this trial may facilitate adoption of short-term urethral catheterization following repair of simple fistula in sub-Saharan Africa and Asia.

Diaphragmatic electromyography during cryoballoon ablation: a novel concept in the prevention of phrenic nerve palsy

BACKGROUND

Hemidiaphragmatic paralysis is the most frequent complication associated with cryoballoon ablation for atrial fibrillation. To date, no preventive strategy has proved effective.

OBJECTIVE

We sought to assess the feasibility of diaphragmatic electromyography during cryoballoon ablation, explore the relationship between altered signals and phrenic nerve palsy, and define characteristic changes that herald hemidiaphragmatic paralysis.

METHODS

Cryoballoon ablation was performed in the right superior pulmonary vein or superior vena cava in 16 mongrel dogs weighing 37.7 ± 2.4 kg, at sites determined by phrenic nerve capture. During ablation, the phrenic nerve was paced at 60 bpm from the superior vena cava while recording diaphragmatic compound motor action potentials (CMAPs) by esophageal decapolar catheters. Diaphragmatic excursion was monitored by fluoroscopy and abdominal palpation.

RESULTS

Before ablation, the CMAP amplitude was 592 (interquartile range 504, 566) μV, initial latency 21.5 ± 4.2 ms, peak latency 64.7 ± 21.1 ms, and duration 101.7 ± 13.3 ms. Hemidiaphragmatic paralysis was obtained in all dogs 62 ± 34 seconds into the cryoapplication. The CMAP amplitude decreased exponentially, with no patterned changes in latencies and duration. Discriminatory analyses by receiver-operating curve characteristics identified a 30% reduction in CMAP amplitude as the most predictive cutoff value for hemidiaphragmatic paralysis (c-statistic 0.965; P<.0001). This criterion presaged diaphragmatic paralysis, as detected by abdominal palpation, by 31 ± 23 seconds.

CONCLUSION

Diaphragmatic electromyographic signals could be reliably recorded during cryoballoon ablation. An exponential decrease in CMAP amplitude precedes diaphragmatic paralysis, with a 30% reduction yielding the best discriminatory potential. A promising safety margin was detected, which merits prospective validation.

How and why women choose sterilization: results from six follow-up surveys

Follow-up surveys were carried out in six countries (Bangladesh, Columbia, El Salvador, Guatemala, Indonesia, and Tunisia) between 1984 and 1986 to assess client decision-making regarding sterilization. The results revealed that women made well-informed, voluntary decisions to be sterilized. They were knowledgeable about other family planning methods and made the decision to be sterilized after consulting their partners, friends, relatives, or other sterilized women. Although their decisions were voluntary, other findings revealed areas for improvement such as client information and education about the risks of the procedure. These data were used to improve program services by emphasizing the need for better information, education, and counseling programs.
