Dataset Information

Indwelling urinary catheters, aortic valve treatment and delirium: a prospective cohort study.

ABSTRACT:

Objectives

To determine whether an association exists between delirium and length of time indwelling urine catheters (IUC) are used in octogenarian patients treated with surgical aortic valve treatment (SAVR) or transcatheter aortic valve implantation (TAVI).

Design

Prospective cohort study.

Setting

Tertiary university hospital covering the western region of Norway.

Participants

Octogenarian patients undergoing elective SAVR or TAVI and willing to participate in the study were eligible. Patients unable to speak Norwegian were excluded. Between 2011 and 2013, 143 consecutive patients were included, and data from 136 of them are presented.

Primary outcome

Delirium.

Results

Logistic regression analysis shows that lower cognitive function was positively associated with delirium (OR 0.86, CI 0.74 to 0.99, p=0.047). Besides, the interaction term in the model shows that IUC use and delirium differed between SAVR and TAVI patients (p=0.04). The difference corresponded to a weaker association between hours of IUC use and delirium for SAVR (OR 1.01, CI: 0.99 to 1.03, p=0.54) compared with that for TAVI (OR 1.04, CI: 1.01 to 1.08, p=0.004).

Conclusions

The association between IUC use and delirium is stronger for octogenarian patients treated with TAVI than for patients who received SAVR. Our results revealed a previously unknown association between the number of hours an IUC is used and postoperative delirium in octogenarian patients treated with TAVI.

Project description:ObjectiveThis meta-analysis aimed to evaluate the effect of bladder training by clamping on bladder urethral function in patients with indwelling urinary catheters used for different durations.DesignSystematic review and meta-analysis.Data sourcesThe UpToDate, Cochrane Library, OVID, PubMed, China National Knowledge Infrastructure, CINAHL and Embase were screened from 1 January 2000 to 28 February 2022.Eligibility criteria for selecting studiesRandomised controlled trials (RCTs) or quasi-experimental designs comparing the efficacy of bladder training in patients with an indwelling urinary catheter by clamping or free drainage before urinary catheter removal were published in English or Chinese.Data extraction and synthesisTwo reviewers independently extracted the data and assessed the quality of studies. Continuous variables were analysed using mean difference and standardised mean difference (SMD) values with a 95% CI. Categorical variables were analysed using relative risk (RR) and 95% CI.Primary and secondary outcome measuresThe primary outcome was urinary tract infection incidence, and secondary outcomes included hours to first voiding, incidence of urinary retention and recatheterisation and residual urine volume.ResultsSeventeen papers (15 RCTs and 2 quasi-RCTs) comprising 3908 participants were included in the meta-analysis. The pooled results of the meta-analysis showed that the clamping group had a significantly higher risk of urinary tract infections (RR=1.47; 95% CI 1.26 to 1.72; p<0.00001) and a longer hour to first void (SMD=0.19; 95% CI 0.08 to 0.29; p=0.0004) compared with the free drainage group. Subgroup analysis of indwelling urinary catheter use durations of ≤7 days indicated that clamping significantly increased the risk of urinary tract infection (RR=1.69; 95% CI 1.42 to 2.02, p<0.00001) and lengthens the interval to first void (SMD=0.26, 95% CI 0.11 to 0.41, p=0.0008) compared with free drainage.ConclusionsBladder training by clamping indwelling urinary catheters increases the incidence of urinary tract infection and lengthens the hours to first void in patients with indwelling urinary catheters use durations of ≤7 days compared with the free drainage. However, the effect of clamping training on patients with an indwelling urinary catheter use duration of >7 days is unclear.
