Abstract: Investigates nurses' catheter management practices, by means of an audit, as documented in a newly-introduced self-administered indwelling catheter-management checklist incorporating four components of catheter care in a catheter-associated urinary tract infection (CAUTI) prevention bundle. Identifies these components of the bundle of care as: minimisation of inappropriate catheter use, aseptic insertion of catheters, adherence to catheter maintenance guidelines, and ongoing review and evaluation of catheter necessity. Shows that implementation of care components decreases bacteriuria rates and CAUTI when used together in standardised clinical checklists and performed collectively by nurses. Employs a quantitative research design as part of a mixed-methods study conducted at two surgical wards in a public hospital in Auckland where 50 nurses completed 175 checklists.
