Bladder catheterisation after female genital fistula repair
Comment
the effect that simple interventions can have on outcome in this physiologically complex and unstable disorder. Findings from the ongoing HeadPoST trial (ClinicalTrials.gov, NCT02162017), comparing the effectiveness of the lying flat (0°) head position with the sitting up (≥30°) head position in the first 24 h of admission to hospital with acute stroke, are likely to be similarly important in this regard. Finally, the low rate of patients refusing to participate in AVERT shows that patients also see the importance of simple, pragmatic research questions. Ironically, the main barriers to more such research are those put up by agencies intended to represent the public interest: the trial regulators with their unnecessarily complex bureaucratic framework for trial performance, which often results in trial prevention, and the medical research funding agencies that in many countries have little interest in the needs of patients and clinicians for answers to pragmatic questions about making the best use of existing interventions in routine clinical practice.9 Thankfully, those agencies in Australia and the UK that funded AVERT took a different view.

In The Lancet, Mark Barone and colleagues1 report the results of their study aimed at establishing whether 7 day bladder catheterisation is non-inferior to 14 day catheterisation in terms of fistula breakdown after repair, in women with simple genital fistulas. The traditional 14 day duration of catheterisation after fistula repair has been challenged over the years, although this duration has been widely used in practice.2–4 A survey of 40 fistula surgeons by Arrowsmith and colleagues5 reported variability of postoperative catheter drainage strategies ranging from 5 to 42 days. Barone and colleagues carried out their randomised, controlled, open-label study in hospitals in eight African countries. With 261 patients in the 7 day group and 263 in the 14 day group in the study, no significant difference in fistula repair breakdown, the trial’s primary endpoint, was noted between the 7 day and 14 day bladder catheterisation groups (ten [4%] of 250 patients in the 7 day group had repair breakdown vs eight [3%] of 251 in the 14 day group, risk difference 0·8% [95% CI –2·8 to 4·5], falling within the predefined

after catheter removal; infections and febrile episodes potentially related to treatment; catheter blockage; extended hospital stay; and residual incontinence at 3 months. 7 day bladder drainage after repair of simple fistulas was therefore found to be non-inferior to 14 day drainage, indicating that 7 day drainage is a safe and effective way to manage postoperative bladder drainage without any substantial increase in complications. The crucial stage in wound healing, that is mobilisation of fibroblasts, granulation formation, and neovascularisation, occurs at 5 days, with inflammation generally resolving after 7 days.2,6 The findings of Barone and colleagues’ study1 will be welcome news to fistula surgeons who have agonised over the absence of capacity to care for patients, and the fact that patients with fistulas are often relegated to the bottom of theatre lists4 that are frequently loaded with emergencies. Reduction of postoperative catheterisation from 14 days to 10 days without a substantial increase in failure has been estimated to increase the number of patients with fistulas undergoing surgical repair by almost 30%3 without any increase in capital investment.3,4 Because duration of bladder catheterisation is a key determinant of the length of hospital stay, which affects treatment costs and use of hospital beds,6–9 a halving of the duration of bladder drainage would increase the turnover of women getting the opportunity for care. However, possible confounding factors such as inadequacy of consumable supplies, anaesthesia, and nursing services would need to be addressed3,4,8 for the full benefits of such a change in practice to be realised. The socioeconomic benefit of reduced hospital stay, from the perspectives of both patients and health systems, can be enormous in the setting of poorly resourced countries.4
A shortened duration of bladder drainage after simple fistula repair without an increase in the number of breakdowns is most welcome news to patients with fistulas and their caregivers. If the results of Barone and colleagues’ study can be reproduced in another multicentre randomised controlled trial, adoption of its conclusions into clinical practice would substantially expand our capacity to care for patients with fistulas. My hope is that, in the near future, obstetric fistula surgeons will have the evidence-based confidence to reduce the duration of postoperative bladder drainage without any anxiety about increased repair breakdowns.

Emil Kraepelin’s demarcation between dementia praecox and manic depressive illness defined affective disorder as a remitting and recurring disease. He considered that only long-term outcome was useful in assessing accuracy of diagnosis and treatment response in patients.1 The more recent interest in the outcome of single mood episodes probably indicates motives to register and
market drugs rather than assisting clinical practice. This interest has resulted in many 4–8 week randomised trials but few well designed long-term studies in patients with depression.
