Development of the German version of the patient safety climate inventory to the Austrian context

OBJECTIVES: In recent years, patient safety culture (PSC) in hospitals, including its development and measurement, has increasingly received attention in Europe. Even though several instruments have been developed for PSC measurement in European countries, there is, to date, no validated measure to assess PSC in Austria. The study at hand addresses this gap in the evidence base by psychometrically assessing the German ‘Patient Safety Climate Inventory’ (PaSKI) in terms of its potential suitability for the Austrian healthcare system. The goal is to theoretically develop and empirically verify a separate instrument for PSC measurement in Austria. SETTING: Ten hospitals. PARTICIPANTS: Healthcare professionals (n=1202); doctors (n=142), nurse (n=645), other health workers (n=51), medical technology professions (n=170), management/administration (n=76), other (n=20), no response (n=98). PRIMARY AND SECONDARY OUTCOME MEASURES: The pretest was conducted with 101 health professionals. Psychometric evaluations, including exploratory factor analysis and confirmatory factor analysis, were performed with both an original version of the PaSKI and an adapted one. The original PaSKI and the newly adapted ‘Austrian Patient Safety Climate Inventory’ (A-PaSKI) were then compared. RESULTS: The A-PaSKI’s factor structure developed in our study differs from the original 14-factor structure (49 items) of the PaSKI. The new instrument consists of 10 factors (30 items), comprising seven departmental factors, two hospital factors, and one outcome factor. The new instrument A-PaSKI revealed satisfactory results on the model-level and internal consistency. The confirmatory factor analysis for the A-PaSKI (χ2 (360)=1408.245, p=0.0001) showed a good model fit, and the absolute and relative fit indices showed an excellent model adjustment. The construct validity was acceptable for nine and unacceptable for one factor. CONCLUSIONS: This is the first validation study of a standardised safety culture measure in Austrian hospitals. The Austrian version of PaSKI demonstrated good psychometric properties, with acceptable to good internal consistency and construct validity for use in Austrian hospitals.
