BACKGROUND፡ Developing a practical model to assess hospital performance improves the quality of services and leads to patient satisfaction. This study aims to develop and present such a model using the IPOCC (Input, Process, Output, Control and Context) approach.METHODS: This study used a mixed-method research. The statistical population of the qualitative part included 27 experts who were purposefully selected and the sampling process was continued by the snowball method until the data saturation was reached. The quantitative part included 334 managers at different levels within a hospital, who were selected by a random sampling method based on Cochran's formula.RESULTS:  The hospital evaluation model has 5 dimensions with 20 factors: input (human, financial, physical, information and equipment), process (treatment, para-clinical, prevention, management, and leadership processes), outcome (patient, staff and community outcomes and key performance index), control (internal control, external control), context (hospital culture, hospital status, the role of evaluators and community conditions). The value of chi-square was 4689.154, the degree of freedom was 2385, and the ratio of chi-square to the degree of freedom in the model was 1.966, which is an acceptable value. The values obtained from CFI, GFI, and IFI fit indices were acceptable. The SRMR index was 0.1130.CONCLUSIONS: Using a performance assessment model along with the IPOCC approach evaluates hospital processes and the output obtained from the proper implementation of these processes in all areas. The areas include the hospital provided services like the control and context, or the traditional perspectives like physical, human, financial, and equipment resources.KEYWORDS: performance assessment, health management, organizational excellence model
