Developing patient safety scale for hospitals

The study aimed to contribute to the literature with a reliable and valid scale for hospitals to be used in determining the current patient safety culture and following up on its development.

The study was conducted with the participation of 1137 healthcare professionals selected using the convenience sampling method in 3 secondary-care state hospitals and three research and training hospitals, one of which was affiliated with a medical faculty, and two were affiliated with the Health Sciences University. To begin with, to discover the latent structure of the items on the scale, an Exploratory Factor Analysis (EFA) was performed. Additionally, to determine the factor structure of the scale, the Confirmatory Factor Analysis (CFA) method was used. The Cronbach's alpha coefficient was calculated to check the reliability of the responses.

According to Kaiser-Meyer-Olkin (KMO = 0.924) coefficient and the result of Bartlett's test of sphericity (χ ² = 9748.777, df = 770), it was determined that the data structure was suitable for factor analysis. The Cronbach's alpha coefficient of the total scale was found to be 0.921. According to the EFA results, the scale was determined to have seven subscales, which were 1. Organizational Learning, Development, and Communication, 2. Management Support and Leadership, 3. Reporting Patient Safety Events, 4. Number of Personnel and Working Hours, 5. Response to Error, 6. Teamwork, and 7. Working Environment. The goodness-of-fit index results of the scale showed a good model fit (χ / df = 3.04, RMSEA = 0.06, CFI = 0.97, NFI = 0.95, IFI = 0.97, SRMR = 0.06). The Cronbach's alpha coefficients of the subscales varied between 0.66 and 0.91.

The results showed that the Patient Safety Scale for Hospitals is a valid and reliable measurement instrument for healthcare professionals.
