RESUMEN
Health care reforms in Thailand are looking for a better health infrastructure within the urban setting. The urban health center is one of the models tried in many provinces. This study compared the costs--effectiveness of the urban health center in Nakhon Ratchsima with the Maharaj Nakhon Ratchasima Hospital, using diabetes and hypertension as tracer conditions. The point estimates by a retrospective review and cross-sectional study revealed that the overall costs (provider plus patient costs) of the urban health center for these tracers were lower than the costs of the Maharaj Hospital. The effectiveness of treatment at the urban health center was also better. It was concluded that the urban health center should be considered as a better alternative of primary care institution within the urban area.
