Factors influencing the hospitalization cost for stroke patients in J district, Shanghai.

Abstract

Stroke is the main cause of death in Chinese residents, bringing a heavy economic burden to patients. This study aims to explore the characteristics and the factors influencing the hospitalization cost for stroke, and to provide scientific evidence for reducing the economic burden on stroke patients. The data were mainly obtained from the Shanghai Statistics Center for Health. Using the coding system of International Classification of Diseases (ICD)-10, we retrospectively collected the stroke-related first hospitalization records of stroke patients in J district, Shanghai during January 1, 2016 to December 31, 2019 whose main diagnostic disease codes were I61-I63. After cleaning and arranging the data, we counted the first hospitalization cost and length of hospital stay (LOS) of the patients. Univariate analysis was performed using non-parametric tests, and the factors influencing stroke hospitalization cost were further analyzed by multiple linear regression fitting path model. A total of 3 901 stroke patients were included. Ischemic and hemorrhagic stroke patients accounted for 92.59% and 7.41%, respectively, of which the mean hospitalization cost per patient were 12 397.35 yuan and 28 814.72 yuan, respectively, and the mean LOS per patient were 13 days and 19 days, respectively. Hospitalization cost for ischemic stroke mainly consisted of medicine fees, diagnosis fees, and service fees, accounting for 44.70%, 29.92%, and 15.42%, respectively, and hospitalization cost for hemorrhagic stroke mainly consisted of medicine fees, diagnosis fees, consumables fees, and service fees, accounting for 38.76%, 18.33%, 17.59%, and 15.38%, respectively. From 2016 to 2019, the proportion of medicine fees for ischemic stroke was decreased by 19.38 percentage points, and the diagnosis fees and service fees were increased by 8.43 percentage points and 9.04 percentage points, respectively; the proportions of medicine fees and consumables fees for hemorrhagic stroke were decreased by 7.54 percentage points and 13.43 percentage points, respectively, and the proportions of diagnostic fees and service fees were increased by 6.87 percentage points and 10.15 percentage points, respectively. Path analysis results showed that the main direct factors influencing hospitalization cost were the LOS, hospital level, operation, and year, and the main indirect factors were age and hospital level (all P<0.05). The cost burden of stroke patients in Shanghai is relatively heavy, and we should continue to promote the medical reform policy and consolidate the achievements of medical reform. Hospitals should strengthen clinical pathway management and patient health education to improve medical efficiency and reduce invalid hospitalization days. Government departments should continue to improve the medical insurance system, enhance the supervision to medical insurance, and promote health equity.
