The Effect of Accreditation Interventions on Patient Safety Measurement in Operating Rooms of one of Tehran Social Security Hospitals

Accreditation means the systematic evaluation of health care centers with specific standards. The overall purpose of this study was to investigate the effect of accreditation interventions on patient safety measurement in operating rooms of one of the social security hospitals in Tehran.

The present study is cross-sectional in terms of result, application and implementation method, analytical and time. The statistical population is information sources related to the patient safety measure and its sampling is in the period 1391-1399. The sampling method is numerical and includes all the information related to this time period. Data collection tools are receipts that have been extracted by library method from data sources and data centers in coordination with the Quality Improvement Office and the hospital statistics unit. Data analysis was performed using SPSS software and intermittent time series analysis method.

Findings of time series analysis, research has been reported in three forms of incremental effect, decreasing effect and ineffectiveness of the accreditation scheme of the scales. In the patient's safety measure, the results of the fragmentary regression table showed that at the beginning of the study period, the average patient's safety measure was 76.34%. Monthly changes in patient's safety measure were not significant before the intervention (P = 0.43). After the intervention, the mean level of the patient's safety measure did not change suddenly and significantly (P = 0.42). Also, the difference in the trend (slope) of the patient's safety measure before and after the intervention did not change significantly (P = 0.31). But the results showed that after the first intervention, the trend (slope) of the patient's average safety measurement changed significantly (P = 0.000); So that the patient's safety measure after the first intervention has increased seasonally by 1.06%. In general, the results of the study have shown that, as a result of the implementation of the accreditation scheme, the patient's safety measure has increased.

The results show that the implementation of accreditation measures has an effect on patient safety measures. The number of significant measures from 2016 to 2016 shows that the third and fourth editions of the national accreditation standards of Iranian hospitals have been effective. Based on the analyzes performed, it is recommended that the patient's safety measure be increased after the first intervention. Therefore, the implementation of accreditation in hospitals is recommended to managers.
