Analysis of Main Diagnoses of Patients Discharged from a Hospital from 2015 to 2022
Objectives This study aims to analyze the changes in the main diagnoses of discharged patients from a tertiary hospital in Guangzhou to provide a reference for hospital management and resource allocation.Methods A retrospective study was conducted to obtain the annual number of inpatients,gender,age,in-hospital death,total hospitalization cost,the average length of stay,type of medical insurance,main diagnosis of discharged diseases,and other clinical indicators from the medical record system of a hospital from January 1,2015 to December 31,2022.Clinical indicators were compared using nonparametric tests and chi-square tests.Results There were statistical differences between the annual group comparisons in the number of hospitalizations,length of hospitalization,hospitalization expenses,gender,age,type of medical insurance,and number of discharge diagnoses(P=0.000).There was a statistical difference between the groups in the number of main discharge diagnoses over the years(P=0.000).Among them,radiotherapy,chemotherapy,and maintenance treatment for the largest number of malignant tumors increased from 5729 cases in 2015 to 10,014 cases in 2022,but there was no statistical difference in the proportions(P=0.170).Comparing 2015 and 2022,except for the number of in-hospital deaths(1.2％VS 1.1％,P=0.073),there were statistical differences between the other index groups(P=0.000).Conclusions Various factors,including regional differences,hospital levels,policies,and economic conditions,can affect changes in the number of primary discharge diagnoses.The number of malignant tumor-related diagnoses has increased significantly,but the proportion of each diagnosis in the total has not changed significantly.
