This study aimed to evaluate the effectiveness of the vendor-managed inventory (VMI) system for the five highest consumption levels of chronic disease medication in the sub-district health-promoting hospitals (SHPHs) in Laemsing, Chanthaburi, Thailand. The research methods comprised qualitative research, which explored the current inventory management system, and quantitative research, which investigated the inventory control system and the effectiveness of the VMI approach. Effectiveness measured by comparing the difference between before and after VMI implementation and the difference between SHPHs using the traditional approach and those adopting the VMI system. Two indicators comprising inventory management and logistics were used to measure the differences. This study highlighted the advantages of VMI for the inventory of chronic medications, as a smooth demand product. The VMI approach used with a periodic review system was more effective than the traditional approach. It reduced the average stock rate, increased inventory turnover rate, inventory accuracy, and ensured products were delivered in full and on time (DIFOT). Further, the SHPHs staff and the community hospital staff were extremely satisfied with the time efficiency, convenience, practicality, and inventory accuracy.
