Community health workers' mobility in China: Evidence from 2008 to 2017

BACKGROUND: Community health workers (CHWs) are essential to improve the responsiveness of the national health system and the capacity of community health services. Since the implementation of the new program for health system reform in 2009, China has adopted an unprecedented policy to attract and retain CHWs to increase the quantity and quality of CHWs equitably. The policy's effects need to be further determined. The purpose of this study was to illustrate the temporal and spatial dynamics of CHWs' mobility in China from 2008 to 2017. METHODS: This study used a multistage stratified sampling method to collect 14,094 CHW mobility records from 24 counties and 12 districts in six provinces in China for analysis. The data cover the period from 2008 to 2017. Descriptive statistics and chi-square test were adopted to analyse the distribution of mobile CHWs across different years and different subgroups from 2008 to 2017. RESULTS: This study found that China's CHWs were in a state of net inflow from 2008 to 2017. The number of net inflows continued to increase from 2008 to 2011 and had a slight downward trend afterwards. CHW turnover occurred more in rural areas and amongst males, physicians, management and support staff, intermediate and senior professional titles, ≥30 years old group and contractual temporary employees. By contrast, the attraction and retention of CHWs are remarkable amongst nurses, pharmacists, imaging and laboratory technicians, junior title, junior college degree and above and <30 years old group. CONCLUSIONS: China has made great achievements with the policy targeting the attraction and retention of CHWs since the implementation of the new program for health system reform in 2009. However, CHWs in China are faced with the dilemma of an extremely high total mobility, the attraction of CHWs in rural areas is still insufficient, the professional structure of CHWs is unreasonable, and the attrition of high-quality health workers exists. China must pay attention to the fair allocation of urban and rural areas, dynamically adjust the recruitment structure of health technicians, improve the mechanism for attracting and retaining technicians with higher titles and guarantee the benefits of temporary employees.
