The impact of accreditation on nurses' perceptions of quality of care in Iran and its barriers and facilitators

Background: Iran national hospital accreditation was initiated as a government and mandatory program in 2012. The aim of this study was to examine the impact of accreditation on nurses' perceptions of quality of care and to determine those barriers and facilitators needed for effective implementation of accreditation. Methods: A cross-sectional survey conducted in 43 tertiary public hospitals in 5 metropolises, Iran, which successfully passed national accreditation surveys. Participants included nurses with at least 5-year work experience. Overall response rate was 76%, with 1312 of 1706 valid responses included in the data analysis. A questionnaire was applied using a 5-point Likert scale ranging from 1 "strongly disagree" to 5 "strongly agree". In addition, the questionnaire included 2 open-ended questions allowing the respondent to identify barriers and facilitators to the process of for improving accreditation implementation. The relationship between the quality of results and the independent variables was tested using multiple regression analysis. Results: The scales measuring benefits of accreditation had the highest mean score followed by strategic quality planning, education and training, and staff involvement. Regression analysis indicated that leadership, commitment, and support; education and training; rewards and recognition; and staff involvement were factors affecting quality results. Barriers encountered included financial and capital resources, staff, institutional, and patients. Hospital accreditation has a positive impact on quality of care. Conclusions: The findings of this study provide valuable information to policymakers and hospital managers on which to base the process of accreditation and its requirements, and to help reap its benefits.
