This analysis aims to assess theassociation between commune health station (CHS) servicereadiness and health service utilization to inform thedesign of a World Bank project and policies to strengthenprimary health care in Vietnam. Using data drawn from the2015 Vietnam district and commune health facility survey(DCHFS), a series of multivariate negative binomialregressions was estimated to measure the association betweendomains of service readiness and CHS utilization rates(average number of visits per capita). To conclude,investments in improving facility infrastructure (especiallyensuring that facilities have the mandated number of roomsand building area), making available essential equipmentitems, and enabling the CHS to provide hypertension anddiabetes services, whether made independently or together,would all likely increase CHS utilization. Investment inCHSs in zone 3 and zone 2 should be prioritized overinvestments in zone 1, since investments in the former wouldresult in the highest utilization rates.
