Do Primary Healthcare Facilities in More Remote Areas Provide More Medical Services? Spatial Evidence from Rural Western China

Primary healthcare institutions (PHIs) in China have experienced a sizable decline in medical services in recent years. Despite the large regional disparities in China, there is a lack of evidence on the differential patterns of medical services offered by PHIs, especially from a spatial perspective. This study examines whether residents in more remote areas use more medical services offered by township healthcare centers (THCs), a main type of PHIs. Linking medical visits to 923 THCs in a western Chinese province in 2020 with the driving time and geographic coordinates from the Gaode map, a leading map navigation provider in China, we applied a multilevel linear model and a geographically weighted regression to examine spatial heterogeneity in medical service utilization. We showed that a one-hour increase in the shortest driving time between THCs and the local county hospitals was associated with an average 6% increase in THCs outpatient visits and a 0.6% increase in THCs inpatient visits. Our findings suggest that THCs located in more remote areas provided more medical services, especially outpatient services. This study may improve our understanding of the spatial disparity in medical services provision for THCs in western China. We suggest that more attention should be paid to enhance the quality of THCs in remote areas, which deserve a higher priority in the process of improving the quality of primary healthcare. Health policymaking in developing regions such as western China should take geographic factors into account.
