Evidence-based practice (EBP) is essential for clinical decision-making, integrating the best available evidence, clinical expertise, and stakeholder values. In Italy, interest in EBP is growing, and a key step in its promotion is adopting tools to assess nurses' beliefs and behaviors toward EBP. While the EBP Beliefs Scale has been translated and validated in multiple languages, it has yet to be adapted for the Italian context.
This study aims to adapt EBP measurement tools for the Italian context and evaluate their psychometric properties.
This study used an observational cross-sectional design. The process of cross-cultural translation, adaptation, and validation was adopted. A panel of experts culturally adapted the Beliefs Scales (long and short version) through the item and scale content validity (I-CVI, S-CVI). To test the psychometric properties, 409 nurses were asked to complete the two scales. Confirmatory factor analysis was conducted to validate the factor structure within the Italian context. Convergent validity between the long and short versions of the scale was assessed using the correlation coefficient (r), and the reliability was assessed by computing Cronbach's alpha.
The I-CVI and S-CVI for the long and short version ranged from 0.75 to 1.00. The CFA model performed for the long and short version reported a good fit without the need for further refinements. The Cronbach's alpha was higher than 0.80 for both scales. The correlation of 0.615 (p < 0.01) indicated a moderate to strong positive relationship supporting the convergent validity of the short version in relation to the long version.
In time-constrained settings, the short scale should be utilized for efficient assessments and longitudinal tracking of changes. The long version serves as a complementary tool for in-depth analysis, facilitating a deeper understanding of underlying factors and informing targeted interventions to address specific barriers.
The primary aim of this study was to evaluate the impact of the polyhexamethylene biguanide (PHMB) care bundle on the occurrence rates of surgical site infections (SSIs) in paediatric and neonatal cardiac surgery, addressing a critical gap in paediatric-specific infection prevention protocols. A retrospective cohort study included patients under 18 years old who underwent cardiac surgery at IRCCS Policlinico San Donato. Cohort A (n = 117) received the PHMB care bundle from April to December 2023, while Cohort B (n = 801) received conventional care from September 2020 to March 2023. The 1:1 propensity score matching was used to balance covariates between cohorts, resulting in two comparable cohorts (Cohort A = 114 patients and Cohort B = 112). The study found a significant reduction in SSIs among patients receiving the PHMB care bundle compared with those receiving conventional care (1.8% vs. 7.1%, p = 0.048). The comprehensive nature of the PHMB care bundle, including educational programs, preoperative and postoperative antimicrobial treatments, and consistent application of best practices, was instrumental in achieving these outcomes. Implementing antimicrobial care bundles could significantly reduce SSIs in paediatric cardiac surgery. Future research is needed to refine the tested bundle with prospective approaches.
