Unveiling antimicrobial stewardship competence among Italian nurses: results from a nationwide survey.

Abstract

Background: The development of nursing competencies in antimicrobial stewardship (AMS) is influenced by a two-dimensional model, encompassing both internal and environmental factors. In the context of Italian clinical nursing, this study aims to assess and measure these aspects.

Methods: Employing a cross-sectional online survey design, nurses from various clinical specialties in Italy were involved. The questionnaire assessed individual variables, knowledge, attitudes, practices, as well as structural and process-related variables influencing AMS. Statistical analyses were performed, encompassing descriptive statistics, Pearson correlation, and multiple linear regression.

Results: A total of 1,651 nurses aswered the survey, with a participation rate of 50.8%. The participant demographic revealed that 77% were female, and they had an average of 15 years of experience. Workplace and regional factors were found to significantly impact both AMS practices and attitudes. Surgical nurses reported higher practices scores (β = 0.467, P <.01), while critical care nurses scored lower (β= -0.398, P <.01). Regarding perceptions of structure, workplace characteristics significantly influenced nurses' scores, indicating lower perceptions among surgical nurses compared to their medical counterparts (β= -0.315, P <.01).

Conclusions: The study reveals the intricate interplay between internal and external factors that impact nurses' AMS competence. This underscores the urgent need for targeted interventions and education initiatives to enhance nurses' AMS competencies. Specifically, addressing variations in settings and nurses' behaviours becomes imperative for achieving improved patient outcomes.
