Strategies for the removal of short-term indwelling urethral catheters in adults

BACKGROUND

Urinary catheterisation is a common procedure, with approximately 15% to 25% of all people admitted to hospital receiving short-term (14 days or less) indwelling urethral catheterisation at some point during their care. However, the use of urinary catheters is associated with an increased risk of developing urinary tract infection. Catheter-associated urinary tract infection (CAUTI) is one of the most common hospital-acquired infections. It is estimated that around 20% of hospital-acquired bacteraemias arise from the urinary tract and are associated with mortality of around 10%. This is an update of a Cochrane Review first published in 2005 and last published in 2007.

OBJECTIVES

To assess the effects of strategies for removing short-term (14 days or less) indwelling catheters in adults.

SEARCH METHODS

We searched the Cochrane Incontinence Specialised Register, which contains trials identified from CENTRAL, MEDLINE, MEDLINE In-Process, MEDLINE Epub Ahead of Print, CINAHL, ClinicalTrials.gov, WHO ICTRP, and handsearching of journals and conference proceedings (searched 17 March 2020), and reference lists of relevant articles.

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) and quasi-RCTs that evaluated the effectiveness of practices undertaken for the removal of short-term indwelling urethral catheters in adults for any reason in any setting.

DATA COLLECTION AND ANALYSIS

Two review authors performed abstract and full-text screening of all relevant articles. At least two review authors independently performed risk of bias assessment, data abstraction and GRADE assessment.

MAIN RESULTS

We included 99 trials involving 12,241 participants. We judged the majority of trials to be at low or unclear risk of selection and detection bias, with a high risk of performance bias. We also deemed most trials to be at low risk of attrition and reporting bias. None of the trials reported on quality of life. The majority of participants across the trials had undergone some form of surgical procedure. Thirteen trials involving 1506 participants compared the removal of short-term indwelling urethral catheters at one time of day (early morning removal group between 6 am to 7 am) versus another (late night removal group between 10 pm to midnight). Catheter removal late at night may slightly reduce the risk of requiring recatheterisation compared with early morning (RR 0.71, 95% CI 0.53 to 0.96; 10 RCTs, 1920 participants; low-certainty evidence). We are uncertain if there is any difference between early morning and late night removal in the risk of developing symptomatic CAUTI (RR 1.00, 95% CI 0.61 to 1.63; 1 RCT, 41 participants; very low-certainty evidence). We are uncertain whether the time of day makes a difference to the risk of dysuria (RR 2.20; 95% CI 0.70 to 6.86; 1 RCT, 170 participants; low-certainty evidence). Sixty-eight trials involving 9247 participants compared shorter versus longer durations of catheterisation. Shorter durations may increase the risk of requiring recatheterisation compared with longer durations (RR 1.81, 95% CI 1.35 to 2.41; 44 trials, 5870 participants; low-certainty evidence), but probably reduce the risk of symptomatic CAUTI (RR 0.52, 95% CI 0.45 to 0.61; 41 RCTs, 5759 participants; moderate-certainty evidence) and may reduce the risk of dysuria (RR 0.42, 95% CI 0.20 to 0.88; 7 RCTs; 1398 participants; low-certainty evidence). Seven trials involving 714 participants compared policies of clamping catheters versus free drainage. There may be little to no difference between clamping and free drainage in terms of the risk of requiring recatheterisation (RR 0.82, 95% CI 0.55 to 1.21; 5 RCTs; 569 participants; low-certainty evidence). We are uncertain if there is any difference in the risk of symptomatic CAUTI (RR 0.99, 95% CI 0.60 to 1.63; 2 RCTs, 267 participants; very low-certainty evidence) or dysuria (RR 0.84, 95% CI 0.46 to 1.54; 1 trial, 79 participants; very low-certainty evidence). Three trials involving 402 participants compared the use of prophylactic alpha blockers versus no intervention or placebo. We are uncertain if prophylactic alpha blockers before catheter removal has any effect on the risk of requiring recatheterisation (RR 1.18, 95% CI 0.58 to 2.42; 2 RCTs, 184 participants; very low-certainty evidence) or risk of symptomatic CAUTI (RR 0.20, 95% CI 0.01 to 4.06; 1 trial, 94 participants; very low-certainty evidence). None of the included trials investigating prophylactic alpha blockers reported the number of participants with dysuria.

AUTHORS' CONCLUSIONS

There is some evidence to suggest the removal of indwelling urethral catheters late at night rather than early in the morning may reduce the number of people who require recatheterisation. It appears that catheter removal after shorter compared to longer durations probably reduces the risk of symptomatic CAUTI and may reduce the risk of dysuria. However, it may lead to more people requiring recatheterisation. The other evidence relating to the risk of symptomatic CAUTI and dysuria is too uncertain to allow us to draw any conclusions. Due to the low certainty of the majority of the evidence presented here, the results of further research are likely to change our findings and to have a further impact on clinical practice. This systematic review has highlighted the need for a standardised set of core outcomes, which should be measured and reported by all future trials comparing strategies for the removal of short-term urinary catheters. Future trials should also study the effects of short-term indwelling urethral catheter removal on non-surgical patients.

A Project to Increase Nurses' Comfort in Offering Bedpans to Women Laboring With Epidural Analgesia

OBJECTIVE

To improve nurses' comfort in helping laboring woman void on a bedpan after initiation of epidural analgesia, to increase the frequency of bedpan use in the labor and birth unit, and to decrease the use of continuous indwelling Foley catheters during the intrapartum period.

DESIGN

Quality improvement project.

SETTING

A single large, midwestern U.S. hospital (>3,000 births annually), where bedpans are infrequently used after epidural placement.

PARTICIPANTS

Registered nurses on a labor and birth unit.

INTERVENTION/MEASUREMENTS

A 20-minute educational presentation that included current urinary catheter evidence-based practice, preferential use of bedpans, and methods to help women void successfully was taught to all registered nurses in the author's labor unit. Nurses rated on a scale of 0 (not comfortable at all) to 10 (extremely comfortable) their comfort level at helping a woman with a bedpan. Primary data were collected through a convenience sample of anonymous surveys (n = 52) completed by registered nurses regarding their experience with bedpan and catheter use during labor and their comfort level helping women be successful with voiding. This was followed by a retrospective chart audit for women with term, singleton pregnancies who labored with epidural analgesia.

RESULTS

Nurses' comfort levels increased from an average of 5.7 to 7.2 (p = .067). Postepidural bedpan use increased from 5.5% (n = 12) to 19% overall (n = 20; p < .001), with five women using bedpans exclusively. When assisted with bedpan use, 38% (n = 12) of women were able to void 34 of the 53 times it was offered (64%). Use of continuous indwelling Foley catheters decreased from 61.7% (n = 137) to 54.7% (n = 58), and use of intermittent catheterization increased from 30.6% (n = 68) to 37.7% (n = 40).

CONCLUSION

When assisted by nurses educated in and comfortable with different voiding techniques, women may be able to avoid medically unnecessary use of urinary catheters during labor.

Urethral (indwelling or intermittent) or suprapubic routes for short-term catheterisation in hospitalised adults

BACKGROUND

Indwelling urethral catheters are often used for bladder drainage in hospital. Urinary tract infection is the most common hospital-acquired infection, and a common complication of urinary catheterisation. Pain, ease of use and quality of life are important to consider, as well as formal economic analysis. Suprapubic catheterisation can also result in bowel perforation and death.

OBJECTIVES

To determine the advantages and disadvantages of alternative routes of short-term bladder catheterisation in adults in terms of infection, adverse events, replacement, duration of use, participant satisfaction and cost effectiveness. For the purpose of this review, we define 'short-term' as intended duration of catheterisation for 14 days or less.

SEARCH METHODS

We searched the Cochrane Incontinence Group Specialised Register, which contains trials identified from the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, MEDLINE in process, ClinicalTrials.gov, WHO ICTRP and handsearching of journals and conference proceedings (searched 26 February 2015), CINAHL (searched 27 January 2015) and the reference lists of relevant articles.

SELECTION CRITERIA

We included all randomised and quasi-randomised trials comparing different routes of catheterisation for short-term use in hospitalised adults.

DATA COLLECTION AND ANALYSIS

At least two review authors extracted data and performed 'Risk of bias' assessment of the included trials. We sought clarification from the trialists if further information was required.

MAIN RESULTS

In this systematic review, we included 42 trials.Twenty-five trials compared indwelling urethral and suprapubic catheterisation. There was insufficient evidence for symptomatic urinary tract infection (risk ratio (RR) 1.01, 95% confidence interval (CI) 0.61 to 1.69; 5 trials, 575 participants; very low-quality evidence). Participants with indwelling catheters had more cases of asymptomatic bacteriuria (RR 2.25, 95% CI 1.63 to 3.10; 19 trials, 1894 participants; very low quality evidence) and more participants reported pain (RR 5.62, 95% CI 3.31 to 9.55; 4 trials, 535 participants; low-quality evidence). Duration of catheterisation was shorter in the indwelling urethral catheter group (MD -1.73, 95% CI -2.42 to -1.05; 2 trials, 274 participants).Fourteen trials compared indwelling urethral catheterisation with intermittent catheterisation. Two trials had data for symptomatic UTI which were suitable for meta-analysis. Due to evidence of significant clinical and statistical heterogeneity, we did not pool the results, which were inconclusive and the quality of evidence was very low. The main source of heterogeneity was the reason for hospitalisation as Hakvoort and colleagues recruited participants undergoing urogenital surgery; whereas in the trial conducted by Tang and colleagues elderly women in geriatric rehabilitation ward were recruited. The evidence was also inconclusive for asymptomatic bacteriuria (RR 1.04; 95% CI 0.85 to 1.28; 13 trials, 1333 participants; very low quality evidence). Almost three times as many people developed acute urinary retention with the intermittent catheter (16% with urethral versus 45% with intermittent); RR 0.45, 95% CI 0.22 to 0.91; 4 trials, 384 participants.Three trials compared intermittent catheterisation with suprapubic catheterisation, with only female participants. The evidence was inconclusive for symptomatic urinary tract infection, asymptomatic bacteriuria, pain or cost.None of the trials reported the following critical outcomes: quality of life; ease of use, and cost utility analysis.

AUTHORS' CONCLUSIONS

Suprapubic catheters reduced the number of participants with asymptomatic bacteriuria, recatheterisation and pain compared with indwelling urethral. The evidence for symptomatic urinary tract infection was inconclusive.For indwelling versus intermittent urethral catheterisation, the evidence was inconclusive for symptomatic urinary tract infection and asymptomatic bacteriuria. No trials reported pain.The evidence was inconclusive for suprapubic versus intermittent urethral catheterisation. Trials should use a standardised definition for symptomatic urinary tract infection. Further adequately-powered trials comparing all catheters are required, particularly suprapubic and intermittent urethral catheterisation.
