To analyse the trend of COPD patients’ inpatient costs and its influencing factors in the context of the reform of DRG, and to provide reference for the reasonable control of COPD inpatient costs.
ITSA were used to analyse the trend of COPD patients’ inpatient costs in a tertiary general hospital from 2018 to 2022, and univariate analysis, stepwise regression analysis and RFM were used to analyse the factors influencing the inpatient costs and the degree of significance of COPD patients’ inpatient costs after the official operation of the DRG.
The results of ITSA showed that the overall inpatient costs of COPD patients decreased significantly and by an average of 1.82% per month during the DRG operation stage; the integrated medical service fee, drug fee, and consumable fee all showed a decreasing trend during the DRG operation stage, by an average of 1.06%, 1.67%, and 4.98% per month, respectively, but the proportion of the integrated medical service fee increased compared with that before the DRG reform by 7.18%; The stepwise regression results showed that the number of hospital days (β=0.584), admission status (β=0.294), whether surgery (β=0.125), whether traditional Chinese medicine (β=0.084), and drug share ratio (β=0.099) had a statistically significant impact on COPD hospitalisation costs (P<0.05); and the results of the Random Forest model analysis showed that hospital days, admission status, drug share ratio were the most important factors influencing COPD hospitalisation costs. status, and medication ratio were the key factors affecting COPD hospitalisation costs.
DRG can effectively promote medical institutions to strengthen cost management and reduce the economic burden of disease. Hospitals should further reduce the cost of COPD and the economic burden of patients by reducing the number of inpatient days, strengthening the management of critically ill patients, and promoting the rational use of drugs.
