Analysis of hospitalization expenditures and influencing factors for inpatients with chronic bronchitis based on SHA2011 in a central Province of China

This study compared the hospitalization expenses of patients with chronic bronchitis in a central province (Province A) in China to estimate the direct medical cost of the family. Our data included hospitalization records of 30,341 patients with chronic bronchitis from five urban general hospitals in Province A. Using descriptive statistics and regression analysis, we explored the relevant factors affecting hospitalization expenses. Our study results have indicated that from 2016 to 2020, the medical expenditure of patients with chronic bronchitis increased annually, with an average annual growth rate of 22.65%. Among all kinds of expenses, the hospitalization expenses, drug cost, bed cost, test cost and other cost of UEMI (Urban Employee Medical Insurance) are higher than that of other types of medical insurance. The check-up fees of CMI (Commercial Insurance) are lower than that of other types of insurance. Between 2016 and 2019, the average medical expenses per patient with chronic bronchitis increased by 44%, which is the highest average medical expenses among patients aged 60-70. And the highest average medical expenditure emerged when the number of service days is between 5 and 10 days. The increase in expenditure could be attributed to the rapid development of medical technology and the increasing medical demand of the people. Overall, the results of our study implied a significant increase in medical expenses for patients with chronic bronchitis from 2015 to 2020, indicating that chronic bronchitis could bring heavy economic pressures to patients, their families and society.
