Over the past few decades, Vietnam has experienced a substantial improvement in health outcomes, providing an example of a low-income country that has achieved a major success in public health despite the lack of resources. However, inequalities in access to healthcare services persist among the poor, ethnic minorities, and other vulnerable groups. To address this issue, the Vietnamese government implemented a healthcare support program in ethnic minority areas in 2013. We examine the effects of this program on healthcare utilization among older individuals aged 55-74. Employing a difference-in-differences approach and data from the Vietnam Household Living Standards Survey from 2008 to 2018, we find that the program has a positive effect on inpatient visits at public health facilities. However, the program has no impact on outpatient visits. Additional analysis reveals that the program increases outpatient visits at commune health stations and inpatient visits at district hospitals. There is also suggestive evidence of a switch from private to public facilities. Our results suggest that providing healthcare resources to disadvantaged areas can increase healthcare utilization of older people, which can, in turn, improve their health outcomes.
