Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention is the use of a sterile wipe, containing 0.1% chlorhexidine solution, for meatal cleaning prior to urinary catheter insertion. The intervention will be delivered by a specific staff member or members at the hospital.
A single wipe will be used once, for the cleaning process, which should take approximately 15 seconds.
The intervention will be administrated by a registered nurse or medical doctor.
Adherence will be monitored through audits of medical records.
Intervention code [1] 330663 0
Prevention
Comparator / control treatment
The control is the use of a sterile wipe, containing 0.9% normal saline, for meatal cleaning prior to urinary catheter insertion.

18 Years
Maximum age
No limit

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Following randomisation, the allocation of participant to groups will be restricted to a password protected file, only accessible by one researcher. Data on allocation will only accessible by one researcher not involved with data collection.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Participants will be randomised (double-blind) in a 1:1 ratio and allocated to either a usual care followed by intervention or intervention followed by usual care. Randomisation and blinding will be coordinated by a researcher not involved with data collection, through computer generated randomisation by another researcher not involved in data collection.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
Intervention assignment

Efficacy
Statistical methods / analysis
The dependent variable for analysis will be a confirmed catheter associated urinary tract infection (CAUTI) within 7 days of catheter insertion (No, Yes). Descriptive analysis will present observed proportions for the control and intervention condition, unadjusted for clustering by hospital. Data will be analysed by logistic regression to estimate the odds of CAUTI within 7 days of catheter insertion associated with the intervention condition, compared with the control condition. The model specification will include a binary fixed effect for the intervention and a fixed effect for each hospital (strata). Model results will provide information about the marginal difference in proportions as point estimates with bootstrapped 95% confidence intervals. The null hypothesis is that CAUTI proportions are equal between control and intervention arms, which will be tested against a two-sided alternative hypothesis. Statistical significance will be defined a p-value < 0.05.

Secondary outcomes:

The analysis will follow the same steps as per the primary outcome for catheter-associated asymptomatic bacteriura.

Time to first CAUTI will be described using Kaplan-Meier survival curves. A log-rank (Mantell- Cox) test will be used to compare survival distributions for control and intervention arms. A Cox proportional hazard model will be developed to estimate the hazard of CAUTI (yes or no), comparing those in the control and intervention arms. The proposed null hypothesis is that use of chlorhexidine 0.1% will not increase the hazard of a CAUTI compared to saline 0.9%. Hazard ratio will be adjusted for age, sex, and other clinically relevant patient characteristics assessed at baseline.
