Nurses and personal care workers require knowledge and confidence to deliver person-centred, evidence-based care to aged care residents with indwelling urinary catheters (IDC). A scoping review found gaps in healthcare workers’ knowledge about IDC care (Huang et al., 2023). To build capacity of the aged care workforce to care for residents with IDCs, we designed a person-centred, evidence-based IDC bundle and are evaluating it through a multi-centre, facility-level cluster randomised controlled feasibility trial. A cross-sectional baseline survey was conducted among residential aged care staff (n = 150) across three Australian states. Outcomes included knowledge performance (% correct) and confidence across four domains: Person-Centred Care, Clinical Assessment, Infection/Policy, and Management & Escalation. Associations between professional and demographic characteristics, confidence, and knowledge were examined using bivariate and multivariable analyses. Knowledge accuracy was high for core safety principles but lower for some clinical decision-making areas. Professional role (RN vs EN) was consistently associated with confidence across domains (p ≤ .046), with career stage also showing significant associations. In multivariable analysis, Clinical Assessment confidence independently predicted knowledge performance (β = .230, p = .005), explaining 5.3% of variance. Some subgroup analyses were limited by sparse data. Professional role and career stage are key factors influencing confidence in IDC care in residential aged care. Clinical assessment confidence revealed modest but independent association with objective knowledge. These findings inform targeted education strategies and provide a benchmark for evaluating the IDC-IMPROVE intervention.
