Effect of China's maternal health policy on improving rural hospital delivery: Evidence from two cross-sectional surveys.

This population-based cross-sectional study aims to explore the effect of China's Rural Hospital Delivery Subsidy (RHDS) policy on the utilization of women's hospital delivery between rural and urban areas. A total of 2398 women were drawn from the Fourth and Fifth National Health Service Surveys, from the Shaanxi province. A generalized linear mixed model was used to analyze the influence of the RHDS policy on the hospital delivery rate. Concentration index and decomposition methods were used to explore the equity of hospital delivery utilization. Prior to introduction of the RHDS policy, the difference in hospital delivery rates was -0.09 (95% CL: -0.16, -0.01) between rural and urban women when adjusting the influence of socioeconomic factors on hospital delivery; after implementation of the policy, the difference was reduced to 0.02 (95% CL: -0.01, 0.06). The horizontal inequity index was reduced from 0.084 to 0.009 for rural women and from 0.070 to 0.011 for urban women. China's Rural Hospital Delivery Subsidy policy had some positive effect on reducing the gap between rural and urban women's hospital delivery rate and inequity. However, there is still a pro-rich inequity of hospital delivery utilization for both rural and urban women.
