Relationship between accreditation rank and technical efficiency of the hospitals affiliated to Tehran University of Medical Sciences

Hospital accreditation is assumed as an effective control mechanism for health systems to improve quality and efficiency. Current study thus seeks to look into the relationship between hospitals’ accreditation and efficiency.
for the efficiency measurement, hospital inputs and outputs included the ratio of physician and nurse to bed, mortality and nosocomial infection rate and quality of inpatient services. A sample of 554 patients from the hospitals selected and the researcher-developed questionnaire were distributed by stratified randomization. DEAP and SPSS software deployed for analysis.
Findings: Average hospitals’ technical efficiency score was 0.94 indicating an improvement capacity of %5.1 for hospitals efficiency. The mean quality score was 4.13 out of 5. No correlation established between hospitals accreditation rank and their technical efficiency.
According to the results, it seems efficiency should be also considered in accreditation metrics. In addition, for measuring efficiency, performance based inputs and specifically outputs should be chosen, should reliable results be aimed.
