Geographic Variations in Stroke Inpatient Healthcare Utilization and Hospital Expenditure Equity in China

Abstract

Background: Stroke is a devastating disease that imposes a heavy financial burden on patients and their families and a significant economic cost on a nation’s healthcare system. Under China’s fragmented health insurance system, it was unclear whether geographic variations in healthcare utilization and hospital expenditures lead to healthcare inequities for stroke inpatients. This study assesses the geographic variations in stroke patients’ healthcare utilization and hospital expenses and the potential geographical influencing factors. Methods: Covering all municipalities and provinces in mainland China, our main data were a 5% random sample of stroke claims from the Urban Employees Basic Medical Insurance (UEBMI) and Urban Residents Basic Medical Insurance (URBMI) schemes from 2013 to 2016, totaling 217969 inpatients and 280804 admissions. The Theil index was employed to evaluate the (in)equity in healthcare utilization and hospital expenditures across all 31 mainland Chinese provinces. Using multiple linear regression analysis, the geographic influencing factors, comprising ability to deliver healthcare, geographical accessibility of health services, healthcare-seeking and economic factors, were explored.Results: UEBMI stroke inpatients had higher hospital costs and longer ALOS, but lower OOP expenses than those with URBMI. UEBMI insurance had a lower Theil index value than the URBMI scheme. Stroke patients’ healthcare utilization and hospital expenditures showed significant differences both within and between regions. The intra-region Theil (in)equality index value was higher than the inter-region Theil index, with the Theil index highest within eastern China, China’s richest and most developed region. The ability to deliver healthcare, the enabling factors and the provincial-level economic factors had significant effects (P<0.05) on healthcare utilization and hospital expenses.Conclusions: Our data revealed significant geographic variation in healthcare utilization and hospital expenditures for stroke patients. In addition to differences in the coverage and reimbursements of the UEBMI-URBMI schemes, disparities within regions were associated with the ability to deliver healthcare (open hospital beds per 100 patients), the enabling factors (regional reimbursement rate and regional education level) and the provincial-level economic factors (GDP per capita). China’s fragmented urban health insurance schemes require further reform to ensure better equity in healthcare utilization and hospital expenses.
