Analysis of the Medication in DRG Overspending Cases of Coronary Heart Disease Patients Based on a New Grey Correlation Method
Objective:To explore the drug cost overrun of hospitalized patients with coronary heart dis-ease and the correlation between various factors after the implementation of the Diagnosis Related Groups(DRG)payment policy.Methods:Basic cost and medication information of inpatients with coronary heart disease from January 2022 to March 2023 in the Second Affiliated Hospital of Nanjing Medical University were collected,a new grey correlation method was used to analyze the correlation between the total drug cost and the amount of various drugs.Results:A total of 1421 cases were included,and the overspend cases accounted for 47.15%of the total cases,of which 53.73%of the cases were mainly due to Western medicine.The top three correlations of the total drug cost of hospitalized patients with coronary heart dis-ease were the cost of drugs in the digestive tracts and metabolism,cardiovascular system drugs,and blood and hematopoietic organ drugs,the cost of enoxaparin sodium and adjuvant drugs such as nicotinamide and sulfotanshinone sodium injections were the main factors affecting the total drug cost of inpatients.Conclu-sion:Although the drug costs for hospitalized patients with coronary heart disease under the DRG policy have been reasonably controlled,the use of adjuvant drugs still needs to be closely monitored.
