Evaluation of Performance Indicators of Qazvin Educational and Medical Centers before and after the Implementation of the Health System Transformation Plan: Interrupted Time Series Analysis

Background and Objectives: The present study was conducted to investigate the status of performance indicators in hospitals affiliated to Qazvin University of Medical Sciences before and after the implementation of the transformation plan. Methods: This descriptive-analytical study was performed longitudinally based on hospital data. The data collection tool was a checklist including general characteristics of hospitals and performance indicators. Data analysis was performed using Interrupted time series analysis (ITS) and Statistical software for data science (STATA) v.15. Chow test was used to determine the structural fractures in the studied time series. Results: Hospitals’ performance indicators were examined. In the first month after the intervention, bed rotation increased significantly by 1.148 (P<0.005). The trend of bed rotation after the intervention increased by 0.060 per month (P=0.032). In the first month after the intervention, the decrease or increase in the length of stay in different hospitals was not significant (P>0.005). The length of stay after the intervention increased by 0.170 per month. In the first month after the intervention, the decrease in bed occupancy percentage was 41% (P=0.005) which is significant. The trend of bed occupancy percentage after the intervention was more than 2% per month (P<0.005). Conclusion: The transformation plan in the period before and after implementation in all studied hospitals has positive effects and has made changes in most performance indicators. This plan is especially beneficial for people who have fallen ill due to a lack of financial resources and have not been able to seek treatment.
