by Xinjuan Zhou, Xinrui Li, Haiyi Chen, Jing Deng Background This study evaluates the association between China’s Employees’ Basic Medical Insurance (EBMI) outpatient pooling policy and outpatient service utilization among middle-aged insured individuals (aged 45–60). By analyzing outpatient service use, visit frequency, and out-of-pocket (OOP) expenditures, the study documents utilization patterns associated with the policy and explores their implications for healthcare-seeking behavior among middle-aged enrollees, providing evidence that may inform future adjustments to outpatient coverage design.
Methods Using cross-sectional data from the 2018 wave of the China Health and Retirement Longitudinal Study (CHARLS), this study employed a logistic regression model to examine the effect of the outpatient pooling policy and different levels of outpatient benefit coverage on the probability of outpatient visits. A zero-inflated negative binomial regression model was used to analyze the impact on the frequency of outpatient visits, and a Tobit model was applied to assess its effect on out-of-pocket outpatient expenditures.
