What influences antibiotic initiation? Developing a scale to measure nursing behaviour in residential aged‐care facilities
Abstract
Abstract Aim The purpose of the current study was to develop and assess the psychometric properties of a measure that captures nursing behaviours that have the potential to influence the initiation of antibiotics in residential aged‐care facilities. Design Cross‐sectional online survey. Method One hundred and fifty‐seven nurses completed an online survey. The survey consisted of two clinical vignettes and measures of tolerance of uncertainty and anxiety. The vignettes consisted of the most common presentations (urinary tract infections and upper respiratory tract infections) of two hypothetical residents in aged‐care facilities. The vignettes provided participants with incremental information with varying levels of symptoms, input from other people and availability of test results. Both vignettes were subjected to exploratory factor analysis. Results The results focus on the 16 items in the second vignette which resulted in the extraction of three factors. The derived factors were labelled as follows: (i) Noting and Calling GP, (ii) Consult a Colleague and (iii) Immediate Assessment and Antibiotics. Reliability analysis revealed excellent to satisfactory reliability. All three scales were significantly correlated with measures of clinical tolerance of uncertainty, and the ‘noting and calling GP’ scale was also negatively correlated with measures of anxiety and general tolerance of uncertainty. The measure showed satisfactory reliability and validity for capturing nursing behaviours that have the potential to influence decisions regarding antibiotics. As such, the current study provides a first step towards addressing the lack of ecologically valid measures that capture the complex and nuanced context of nurses’ behaviours in RACF that have the potential to inform future stewardship interventions.
