Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
For a period of 12-months, at admission, and daily thereafter until discharge from ICU, critically ill patients admitted to the intensive care unit will have bathing performed using 2% chlorhexidine-impregnated washcloths.

Specifically, bathing will be completed according to manufacturer instructions. In brief, washcloths will be used in sequential order to rinse all body surfaces with the exception of the face during bathing with the 2% chlorhexidine-impregnated cloths in order to avoid exposure of the mucous membranes to the eyes and mouth. A manufacturer-produced video will be used to instruct nurses on the application of these cloths. Such washing will be applied within 4-6 hours of admission and, thereafter, daily at practically convenient times and at intervals no greater than 24 hours.

The adherence to the use of the 2% chlorhexidine-impregnated washcloths will be performed by medical record audit of medication use.

Prevention
Comparator / control treatment
For the 12-month period preceedinig the introducing of bathing all critically ill patients admitted to the intenisve care unit.

Specifically, bathing during this period involved intensive care staff sequentially washing all body surfaces as they deemed appropriate using the available soaps, detergents and personal cleaning agents provided by the hospital. It was routine during this period to wash patients within 4-6 hours of admission and, thereafter, daily at practically convenient times and at intervals no greater than 24 hours.

Data collected for this period is from the Austin Hospital from March 2013 to February 2014.

Efficacy
Statistical methods / analysis
Baseline comparisons will be performed using Fisher’s exact tests and reported as n (%). Continuous normally distributed variables will be compared using Student t-tests and reported as means (standard deviation), while non-normally distributed data will be compared using Wilcoxon rank-sum tests and reported as medians [interquartile range]. Changes over time will be determined using repeated measures mixed linear modeling with each patient treated as a random effect, and therapy group, time and the interaction of therapy group and time as effect fixed effects.

All analysis will be performed by using SPSS version 19.0 (SPSS Inc, Chicago, IL, USA).
