Advancing measurement of patient safety culture.

ABSTRACT: OBJECTIVE: To examine the psychometric and unit of analysis/strength of culture issues in patient safety culture (PSC) measurement. DATA SOURCE: Two cross-sectional surveys of health care staff in 10 Canadian health care organizations totaling 11,586 respondents. STUDY DESIGN: A cross-validation study of a measure of PSC using survey data gathered using the Modified Stanford PSC survey (MSI-2005 and MSI-2006); a within-group agreement analysis of MSI-2006 data. Extraction Methods. Exploratory factor analyses (EFA) of the MSI-05 survey data and confirmatory factor analysis (CFA) of the MSI-06 survey data; Rwg coefficients of homogeneity were calculated for 37 units and six organizations in the MSI-06 data set to examine within-group agreement. PRINCIPAL FINDINGS: The CFA did not yield acceptable levels of fit. EFA and reliability analysis of MSI-06 data suggest two reliable dimensions of PSC: Organization leadership for safety (alpha=0.88) and Unit leadership for safety (alpha=0.81). Within-group agreement analysis shows stronger within-unit agreement than within-organization agreement on assessed PSC dimensions. CONCLUSIONS: The field of PSC measurement has not been able to meet strict requirements for sound measurement using conventional approaches of CFA. Additional work is needed to identify and soundly measure key dimensions of PSC. The field would also benefit from further attention to strength of culture/unit of analysis issues.

Project description:BackgroundRecent decades have seen increased attention to patient safety in health care. This is often in the form of programmes aiming to change professional behaviours. Health professionals in hospitals have traditionally resented such initiatives because patient safety programmes often take a managerialist form that may be interpreted as a challenge to professional identity. Research, however, has mostly paid attention to the role of physicians. This study aims to highlight how such programmes may affect professional nursing identity.MethodsWe qualitatively investigated the implementation of a patient safety programme in Norway, paying attention to changes in nurses' practices and values. Based on purposive sampling, two group interviews, four individual interviews and five hours of observational studies were conducted in a hospital department, involving ten nurses and three informants from the hospital management. Interviews were conducted in offices at the hospital, and observations were performed in situ. All the interviews lasted from one to one and a half hours, and were recorded and transcribed ad verbatim. Data was analysed according to ad-hoc meaning generation.ResultsThe following analytical categories were developed: reconstructing trust, reconstructing work, reconstructing values and reconstructing professional status. The patient safety programme involved a shift in patient safety-related decisions, from being based on professional judgement to being more system based. Some of the patient safety work that previously had been invisible and tacit became more visible. The patient safety programme involved activities that were more in accordance with the 'cure' discourse than traditional 'care' work within nursing. As a result, this implied a heightened perceived professional status among the nurses. The safety programme was - contrary to the 'normal' resistance against audit systems - well received because of the raised perceived professional status among the nurses.ConclusionsReconstructing trust, work, values and status, and even the profession itself, is being reconstructed through the work involved in implementing the procedures from the safety programme. Professional knowledge and identity are being challenged and changed, and what counts as good, professional nursing of high quality is being reconstructed.

Project description:BackgroundDeveloping a patient safety culture was one of the recommendations made by the Institute of Medicine to assist hospitals in improving patient safety. In recent years, a multitude of evidence, mostly originating from developed countries, has been published on patient safety culture. One of the first efforts to assess the culture of safety in the Eastern Mediterranean Region was by El-Jardali et al. (2010) in Lebanon. The study entitled "The Current State of Patient Safety Culture: a study at baseline" assessed the culture of safety in Lebanese hospitals. Based on study findings, the objective of this paper is to explore the association between patient safety culture predictors and outcomes, taking into consideration respondent and hospital characteristics. In addition, it will examine the correlation between patient safety culture composites.MethodsSixty-eight hospitals and 6,807 respondents participated in the study. The study which adopted a cross sectional research design utilized an Arabic-translated version of the Hospital Survey on Patient Safety Culture (HSOPSC). The HSOPSC measures 12 patient safety composites. Two of the composites, in addition to a patient safety grade and the number of events reported, represented the four outcome variables. Bivariate and mixed model regression analyses were used to examine the association between the patient safety culture predictors and outcomes.ResultsSignificant correlations were observed among all patient safety culture composites but with differences in the strength of the correlation. Generalized Estimating Equations for the patient safety composite scores and respondent and hospital characteristics against the patient safety grade and the number of events reported revealed significant correlations. Significant correlations were also observed by linear mixed models of the same variables against the frequency of events reported and the overall perception of safety.ConclusionEvent reporting, communication, patient safety leadership and management, staffing, and accreditation were identified as major patient safety culture predictors. Investing in practices that tackle these issues and prioritizing patient safety is essential in Lebanese hospitals in order to improve patient safety. In addition, further research is needed to understand the association between patient safety culture and clinical outcomes.
