Differences in regional distribution and inequality in health workforce allocation in hospitals and primary health centers in China: A longitudinal study

Background: In 2009, China launched a new round of healthcare reform to provide households with secure, efficient, convenient, equitable and affordable healthcare services. Healthcare reform is underpinned by three critical pillars: the health workforce, funding, and infrastructure, with reform of the health workforce being particularly significant. Objective: This study analyses the disparities in regional distribution and the inequity of healthcare workforce allocation across hospitals and primary health centers in China over twelve years. Design: Retrospective longitudinal data from the National Health Statistics Yearbook 2011-2022 and National Statistical Yearbook in China from 2011 to 2022 were collected for analysis. Participants: The focus was on hospitals and primary health centers, explicitly examining their health technician and nursing workforce. Methods: The research utilized four key indicators of the healthcare workforce to evaluate the distribution of health resources between hospitals and primary health centers. Furthermore, the Gini coefficient and Theil index were employed to assess the inequality in allocating the health workforce. Results: Between 2010 and 2021, there was a nationwide increase in the ratio of health workers per 1000 population in hospitals and primary health centers. It is noted that rural districts had higher ratios than urban districts in terms of the number of health technicians and nurses per 1000 population, whether in hospitals or primary health centers; western districts had higher ratios than eastern and central districts did. In the same year, at different levels of medical institutions, the Theil indices of health technicians and nurses in hospitals were lower than those in primary health centers in terms of both demographic and geographical dimensions. Regarding the allocation of the health workforce by population, the Gini coefficient remained below 0.3, while for geographical allocation, it exceeded 0.4. Conclusions: This study analyzed the temporal trends and inequality of health-resource allocation at the hospital and primary health center levels in China, noting trends of improvements in the quantity and inequality in health workforce allocation from 2010 to 2021, suggesting the success of the government's efforts to advance healthcare reform since 2009. The allocation of health workforce based on population exhibits greater fairness compared to geographical distribution. (c) 2024 Elsevier Ltd.
