Objectives
Panzhihua has implemented the Diagnosis Related Groups (DRGs) since 2018, and the quality of medical under the DRG-Based Payment System is concerned. This study aimed to examine the characteristics of patients under the DRG payment system based on the related factors, length of stay, readmission of inpatients.
Methods
We conducted a retrospective cohort study using data from Hospital Information System (HIS) from 2019 . The study used logistic regression analysis to investigate the factors related to hospitalization time and readmission rate of patients under the DRG payment system.
Results
In this study ,68210 inpatients were included in the study. Among these inpatients ,5.84% were readmitted within 30 days.The factors associated with the increased risk of readmission included age, DRG payment, admission, critical condition, and discharge (p <0.05). Surgical patients had the highest risk of readmission within 30 days (OR=1.04995% CI:0.982-1.122). Among the inpatients readmitted within 30 days, 79.65% of them were readmitted within 14 days. 11.49% of the inpatients were transferred to other hospitals.
Conclusion
The study shows a significant correlation between readmission and age, DRG payment, admission, critical condition, and discharge. The results suggested that high risk groups need in-depth examination and evaluation when discharged and admitted to hospital.
