The stepped wedge study design allows each ward to act as its own control. During the control phase, the cleaning and disinfection of shared medical equipment are undertaken by PSAs according to hospital policies. The intervention phase introduces 15 additional hours per week, purely dedicated to the cleaning and disinfection of shared medical equipment. During the intervention phase, PSAs will be educated on correct cleaning and disinfection technique. To confirm equipment is being properly cleaned during the intervention, auditing with fluorescent markers (FM) will allow feedback to PSA staff. This design allows the comparison between routine (control) and enhanced (intervention) disinfection.
