Midwife managed delivery unit: a randomised controlled comparison with consultant led care.

Abstract Objective: To examine whether intrapartum care and delivery of low risk women in a midwife managed delivery unit differs from that in a consultant led labour ward. Design: Pragmatic randomised controlled trial. Subjects were randomised in a 2:1 ratio between the midwives unit and the labour ward. Setting: Aberdeen Maternity Hospital, Grampian. Subjects—2844 low risk women, as defined by existing booking criteria for general practitioner units in Grampian. 1900 women were randomised to the midwives unit and 944 to the labour ward. Main outcome measures: Maternal and perinatal morbidity. Results: Of the women randomised to the midwives unit, 647 (34%) were transferred to the labour ward antepartum, 303 (16%) were transferred intrapartum, and 80 (4%) were lost to follow up. 870 women (46%) were delivered in the midwives unit. Primigravid women (255/596, 43%) were significantly more likely to be transferred intrapartum than multigravid women (48/577, 8%). Significant differences between the midwives unit and labour ward were found in monitoring, fetal distress, analgesia, mobility, and use of episiotomy. There were no significant differences in mode of delivery or fetal outcome. Conclusions: Midwife managed intrapartum care for low risk women results in more mobility and less intervention with no increase in neonatal morbidity. However, the high rate of transfer shows that antenatal criteria are unable to determine who will remain at low risk throughout pregnancy and labour.

Surgical management of pelvic organ prolapse in women: the updated summary version Cochrane review

Introduction and hypothesisA previous version of the Cochrane review for prolapse surgery in 2008 provided two conclusions: abdominal sacrocolpopexy had lower recurrent vault prolapse rates than sacrospinous colpopexy but this was balanced against a longer time to return to activities of daily life. An additional continence procedure at the time of prolapse surgery might be beneficial in reducing post-operative stress urinary incontinence; however, this was weighed against potential adverse effects. The aim of this review is to provide an updated summary version of the current Cochrane review on the surgical management of pelvic organ prolapse.MethodsWe searched the Cochrane Incontinence Group Specialised Register and reference lists of randomised or quasi-randomised controlled trials on surgery for pelvic organ prolapse. Trials were assessed independently by two reviewers.ResultsWe identified 40 trials including 18 new and three updates. There were no additional studies on surgery for posterior prolapse. Native tissue anterior repair was associated with more anterior compartment failures than polypropylene mesh repair as an overlay (RR 2.14, 95% CI 1.23–3.74) or armed transobturator mesh (RR 3.55, 95% CI 2.29–5.51). There were no differences in subjective outcomes, quality of life data, de novo dyspareunia, stress urinary incontinence, reoperation rates for prolapse or incontinence, although some of these data were limited. Mesh erosions were reported in 10% (30/293). Including new studies on the impact of continence surgery at the time of prolapse surgery, meta-analysis revealed that concurrent continence surgery did not significantly reduce the rate of post-operative stress urinary incontinence (RR 1.39, 95% CI 0.53–3.70; random-effects model).ConclusionThe inclusion of new randomised controlled trials showed that the use of mesh at the time of anterior vaginal wall repair reduced the risk of recurrent anterior vaginal wall prolapse on examination. However, this was not translated into improved functional or quality of life outcomes. The value of a continence procedure in addition to a prolapse operation in women who are continent pre-operatively remains uncertain. Adequately powered randomised controlled trials are needed and should particularly include womens perceptions of prolapse symptoms and functional outcome.

Antimicrobial catheters for reduction of symptomatic urinary tract infection in adults requiring short-term catheterisation in hospital: a multicentre randomised controlled trial

BACKGROUND Catheter-associated urinary tract infection (CAUTI) is a major preventable cause of harm for patients in hospital. We aimed to establish whether short-term routine use of antimicrobial catheters reduced risk of CAUTI compared with standard polytetrafluoroethylene (PTFE) catheterisation. METHODS In our parallel, three group, multicentre, randomised controlled superiority trial, we enrolled adults (aged ≥16 years) requiring short-term (≤14 days) catheterisation at 24 hospitals in the UK. Participants were randomly allocated 1:1:1 with a remote computer allocation to receive a silver alloy-coated catheter, a nitrofural-impregnated catheter, or a PTFE-coated catheter (control group). Patients undergoing unplanned catheterisation were also included and consent for participation was obtained retrospectively. Participants and trial staff were unmasked to treatment assignment. Data were collected by trial staff and by patient-reported questionnaires for 6 weeks after randomisation. The primary outcome was incidence of symptomatic urinary tract infection for which an antibiotic was prescribed by 6 weeks. We postulated that a 3·3% absolute reduction in CAUTI would represent sufficient benefit to recommend routine use of antimicrobial catheters. This study is registered, number ISRCTN75198618. FINDINGS 708 (10%) of 7102 randomly allocated participants were not catheterised, did not confirm consent, or withdrew, and were not included in the primary analyses. Compared with 271 (12·6%) of 2144 participants in the control group, 263 (12·5%) of 2097 participants allocated a silver alloy catheter had the primary outcome (difference -0·1% [95% CI -2·4 to 2·2]), as did 228 (10·6%) of 2153 participants allocated a nitrofural catheter (-2·1% [-4·2 to 0·1]). Rates of catheter-related discomfort were higher in the nitrofural group than they were in the other groups. INTERPRETATION Silver alloy-coated catheters were not effective for reduction of incidence of symptomatic CAUTI. The reduction we noted in CAUTI associated with nitrofural-impregnated catheters was less than that regarded as clinically important. Routine use of antimicrobial-impregnated catheters is not supported by this trial. FUNDING UK National Institute for Health Research Health Technology Assessment Programme.

Randomised controlled trial of conservative management of postnatal urinary and faecal incontinence: six year follow up

Abstract Objective To determine the long term effects of a conservative nurse-led intervention for postnatal urinary incontinence. Design Randomised controlled trial. Setting Community based intervention in three centres in the United Kingdom and New Zealand. Participants 747 women with urinary incontinence at three months after childbirth, of whom 516 were followed up again at 6 years (69%). Intervention Active conservative treatment (pelvic floor muscle training and bladder training) at five, seven, and nine months after delivery or standard care. Main outcome measures Urinary and faecal incontinence, performance of pelvic floor muscle training. Results Of 2632 women with urinary incontinence, 747 participated in the original trial. The significant improvements relative to controls in urinary (60% v 69%) and faecal (4% v 11%) incontinence at one year were not found at six year follow up (76% v 79% (95% confidence interval for difference in means −10.2% to 4.1%) for urinary incontinence, 12% v 13% (−6.4% to 5.1%) for faecal incontinence) irrespective of subsequent obstetric events. In the short term the intervention had motivated more women to perform pelvic floor muscle training (83% v 55%) but this fell to 50% in both groups in the long term. Both urinary and faecal incontinence increased in prevalence in both groups during the study period. Conclusions The moderate short term benefits of a brief nurse-led conservative treatment of postnatal urinary incontinence may not persist, even among women with no further deliveries. About three quarters of women with urinary incontinence three months after childbirth still have this six years later.

A randomized controlled trial of pelvic floor muscle training for stages I and II pelvic organ prolapse

Forty-seven women participated in a pilot study for a multi-centre randomized controlled trial of the effectiveness of pelvic floor muscle training (PFMT) for women with prolapse. Women with symptomatic stage I or II prolapse [measured by Pelvic Organ Prolapse Quantification (POP-Q)] were randomized to a 16-week physiotherapy intervention (PFMT and lifestyle advice; n = 23) or a control group receiving a lifestyle advice sheet (n = 24). Symptom severity and quality of life were measured via postal questionnaires. Blinded POP-Q was performed at baseline and follow-up. Intervention women had significantly greater improvement than controls in prolapse symptoms (mean score decrease 3.5 versus 0.1, p = 0.021), were significantly more likely to have an improved prolapse stage (45% versus 0%, p = 0.038) and were significantly more likely to say their prolapse was better (63% versus 24%, p = 0.012). The data support the feasibility of a substantive trial of PFMT for prolapse. A multi-centre trial is underway.

Sexual function, delivery mode history, pelvic floor muscle exercises and incontinence: A cross-sectional study six years post-partum

Background: There is controversy over the effect of mode of delivery, pelvic floor muscle exercises (PFME), incontinence and sexual function.

Determining the optimal pelvic floor muscle training regimen for women with stress urinary incontinence

Pelvic floor muscle (PFM) training has received Level‐A evidence rating in the treatment of stress urinary incontinence (SUI) in women, based on meta‐analysis of numerous randomized control trials (RCTs) and is recommended in many published guidelines. However, the actual regimen of PFM training used varies widely in these RCTs. Hence, to date, the optimal PFM training regimen for achieving continence remains unknown and the following questions persist: how often should women attend PFM training sessions and how many contractions should they perform for maximal effect? Is a regimen of strengthening exercises better than a motor control strategy or functional retraining? Is it better to administer a PFM training regimen to an individual or are group sessions equally effective, or better? Which is better, PFM training by itself or in combination with biofeedback, neuromuscular electrical stimulation, and/or vaginal cones? Should we use improvement or cure as the ultimate outcome to determine which regimen is the best? The questions are endless. As a starting point in our endeavour to identify optimal PFM training regimens, the aim of this study is (a) to review the present evidence in terms of the effectiveness of different PFM training regimens in women with SUI and (b) to discuss the current literature on PFM dysfunction in SUI women, including the up‐to‐date evidence on skeletal muscle training theory and other factors known to impact on womens participation in and adherence to PFM training.
