BACKGROUND
People requiring long-term bladder draining commonly experience catheter-associated urinary tract infection and other problems.
OBJECTIVES
To determine if certain catheter policies are better than others in terms of effectiveness, complications, quality of life and cost-effectiveness in long-term catheterised adults and children.
SEARCH METHODS
We searched the Cochrane Incontinence Group Specialised Trials Register (searched 28 September 2011). Additionally, we examined all reference lists of identified trials.
SELECTION CRITERIA
All randomised and quasi-randomised trials comparing catheter policies (route of insertion and use of antibiotics) for long-term (more than 14 days) catheterisation in adults and children.
DATA COLLECTION AND ANALYSIS
Data were extracted by two reviewers independently and compared. Disagreements were resolved by discussion. Data were processed as described in the Cochrane Handbook. If the data in trials had not been fully reported, clarification was sought from the authors. When necessary, the incidence-density rates (IDR) and/or the incidence-density differences (IDD) within a certain time period were calculated.
MAIN RESULTS
Eight trials met the inclusion criteria involving 504 patients in four cross-over and four parallel-group randomised controlled trials. Only two of the pre-stated six comparisons were addressed in these trials. Four trials compared antibiotic prophylaxis with antibiotics when clinically indicated. For patients using intermittent catheterisation, there were inconsistent findings about the effect of antibiotic prophylaxis on symptomatic urinary tract infection (UTI). Only one study found a significant difference in the frequency of UTI favouring prophylaxis. For patients using indwelling urethral catheterisation, one small trial reported fewer episodes of symptomatic UTI in the prophylaxis group.Four trials compared antibiotic prophylaxis with giving antibiotics when microbiologically indicated. For patients using intermittent catheterisation, there was limited evidence that receiving antibiotics reduced the rate of bacteriuria (asymptomatic and symptomatic). There was weak evidence that prophylactic antibiotics were better in terms of fewer symptomatic bacteriuria.
AUTHORS' CONCLUSIONS: No eligible trials were identified that compared alternative routes of catheter insertion. The data from eight trials comparing different antibiotic policies were sparse, particularly when intermittent catheterisation was considered separately from indwelling catheterisation. Possible benefits of antibiotic prophylaxis must be balanced against possible adverse effects, such as development of antibiotic resistant bacteria. These cannot be reliably estimated from currently available trials.
背景
需要长期膀胱引流的人群通常会经历与导尿管相关的尿路感染及其他问题。
目的
确定在长期留置导尿管的成人和儿童中,某些导尿管使用策略在有效性、并发症、生活质量和成本效益方面是否优于其他策略。
检索方法
我们检索了Cochrane尿失禁组专业试验注册库(检索日期为2011年9月28日)。此外,我们还查阅了所有已识别试验的参考文献列表。
入选标准
所有比较成人和儿童长期(超过14天)导尿的导尿管使用策略(插入途径和抗生素使用)的随机和半随机试验。
数据收集与分析
由两名审阅者独立提取数据并进行比较。分歧通过讨论解决。数据按照Cochrane手册中的描述进行处理。如果试验中的数据未充分报告,则向作者寻求澄清。必要时,计算特定时间段内的发病密度率(IDR)和/或发病密度差异(IDD)。
主要结果
八项试验符合纳入标准,包括四项交叉试验和四项平行组随机对照试验,共涉及504名患者。在这些试验中,仅涉及预先设定的六项比较中的两项。四项试验比较了抗生素预防与临床指征时使用抗生素的情况。对于使用间歇性导尿的患者,关于抗生素预防对有症状尿路感染(UTI)的影响,研究结果并不一致。只有一项研究发现预防组的UTI发生率有显著差异。对于使用留置尿道导尿管的患者,一项小型试验报告预防组有症状UTI的发作次数较少。四项试验比较了抗生素预防与微生物学指征时使用抗生素的情况。对于使用间歇性导尿的患者,仅有有限的证据表明接受抗生素治疗可降低菌尿率(无症状和有症状)。有微弱证据表明预防性使用抗生素在减少有症状菌尿方面更好。
作者结论
未发现比较导尿管插入替代途径的合格试验。八项比较不同抗生素使用策略的试验数据稀少,特别是将间歇性导尿与留置导尿分开考虑时。抗生素预防的潜在益处必须与可能的不良反应(如抗生素耐药菌的产生)相权衡。目前的试验无法可靠地估计这些情况。
