Association between direct government subsidies and service scope of primary care facilities: a cross-sectional study...

Comprehensive primary care practices, through preconception, preventive, curative, and rehabilitative care, have been a global priority in the promotion of health. However, the scope of primary care services has still been in decline in China. Studies on the factors for primary care service scope have centred on human resources and infrastructure; the role of direct government subsidies (DGS) on services scope of primary care facilities were left unanswered. This study aimed to explore the association between the DGS and services scope of primary care facilities in China.

A multi-stage, clustered cross-sectional survey using self-administrated questionnaire was conducted among primary care facilities of 36 districts/counties in China. A total of 770 primary care facilities were surveyed with 757 (98.3%) valid respondents. Of the 757 primary care facilities, 469 (62.0%) provided us detailed information of financial revenue and DGS from 2009 to 2016. Therefore, 469 primary care facilities from 31 counties/districts were included in this study. Sasabuchi-Lind-Mehlum tests and multivariate regression models were used to examine the inverted U-shaped relationship between the DGS and service scope.

Of 469 PCFs, 332 (70.8%) were township health centres. Proportion of annul DGS to FR arose from 26.5% in 2009 to 50.5% in 2016. At the low proportion of DGS to financial revenue, an increase in DGS was associated with an increased service scope of primary care facilities, whereas the proportion of DGS to financial revenue over 42.5% might cause narrowed service scope (P = 0.023, 95% CI 11.59-51.74%); for the basic medical care dimension, the cut point is 42.6%. However, association between DGS and service scope of public health by primary care facilities is statistically insignificant.

While the DGS successfully achieved equalization of basic preventive and public health services, the disproportionate proportion of DGS to financial revenue is associated with narrowed service scope, which might cause underutilization of primary care and distorted incentive structure of primary care. Future improvements of DGS should focus on the incentive of broader basic medical services provision, such as clarifying service scope of primary care facilities and strategic procurement with a performance-based subsidies system to determine resource allocation.
