Abstract : The availability of good quality,equitable,and affordable drugs in government and private health services is the target and strategic plan of the Indonesian Ministry of Health. This research also ensures safe stock levels and drug management in health facilities.The research applied a retrospective observational method. The percentage (%) of each drug availability was calculated on the day of data collection using methods suggested by the WHO HAI. A set of (50) key drug indicators was selected following the WHO HAI reference guide, which consists of 14 global, 14 regional, and 22 additional drugs. The percentage of key drugs available in public hospitals is higher, i.e., 88% compared to that of private hospitals (70%). Class A public hospitals showed the highest availability (92%) of essential drugs compared to other class of hospitals. The mean availability of drugs in class D private hospitals showed a low value of 61% with the lowest percentage (57%) of safe stock level.Atenolol 50 mg, beclometasone inhalers 50 mcg, clotrimazole cream, and enalapril 5 mg were not found in any of the hospitals studied. The availability of indicator drugs is not met 100% in all hospitals studied; this needs to be improved to ensure that health services can run well. Procurement management policies play an important element in optimizing efforts to increase drug availability;this is supported by the findings of the technical problem of drug procurement, which is a problem in all the hospitals studied
