Abstract

This study aimed to identify appropriateness and efficiency in the DRG payment system by analysing the hospital length of stay and changes in fees before and after the application of DRG payment system. The subjects of the study were a total of 398 patients consisting of 204 for the fee for service system and 194 for the DRG payment system. They received surgery in the Obstetrics and Gynecology (OBGY) department of a general hospital in G metropolitan city between January and December 2013. The mean hospital length of stay was significantly decreased after application of the DRG payment system(p=0.013). Total fees, insurance charges, and deductions increased significantly(p<0.001), and non-payment charges and total deductions decreased significantly(p<0.001). Application of the DRG payment system reduced length of stay, non-payment charges and total patient's cost sharing and increased out-of-pocket, insurance charges, and total fees.
