Precision targeting for more equitable distribution of health professionals in rural China.

A strong health workforce is widely recognized as a prerequisite for health care and a crucial determinant of health system performance. The number of health professionals in China increased following the 2009 health system reform, which, in part, aimed to address the shortage and unequal distribution of health professionals. We examined whether the distribution of health professionals was more equitable following the reform and whether the reform had targeted impacts in terms of the quantity of health professionals. We interacted economic (poor and non-poor counties) and geographic (eastern, central and western regions) dimensions to more precisely target vulnerable areas, focussing on the quantity and distribution of health professionals in rural China. We used a county-level longitudinal dataset from the National Health and Family Planning Commission consisting of 1978 counties in all 31 provinces in rural China, with measurements taken every other year from 2008 to 2014. The distribution of health professionals was summarized using descriptive and interaction analyses. We found a constant improvement in the number of health professionals per 1000 population co-existing with a worsening of the distribution across rural China following the health system reform. Most of the non-poor counties improved faster compared with poor counties across all geographic regions, especially in the western and eastern regions. The growth of the number of health professionals per 1000 population was greatest and fastest in western-non-poor counties and least and slowest in eastern-poor counties. As an example of the 'Central Region Downfall' phenomenon, the central counties (both poor and non-poor) performed poorly in terms of the quantity and distribution of health professionals. Based on an analysis of multiple dimensions, targeted and differential measures should be taken to reduce inequalities, and the central region should not be ignored in efforts to improve the distribution of health professionals in rural China.
