Development of a method for classification of hospitals based on results of the diagnosis-related groups and the principle of case-mix index.

This research used DRGs and CMI to adjust medical waste production through the calculation of DRGs and CMI scores. These scores were used to assess the performances of teaching hospitals in Damascus. The linear correlations between these scores and the annual amount of waste and DRGs values were studied. The differences between the daily waste generations before and after the adjustment process were determined. Accordingly, the highest values of DRGs and CMI Scores were for the pediatric and Al Assad hospitals respectively. Among the teaching hospitals in Damascus, Al Assad has achieved the highest performance. Based on the results, the accuracy and homogeneity of medical waste generation rates were improved, which in turn leads to continuous improvement in the management of medical wastes.
