A public-health approach to site-specific formulary management: addressing deficient drug supplies in Malawi†

Abstract

Maintaining a well-stocked dispensary at a private non-profit clinic in a developing country can often be challenging due to limited financial and human resources. Organizations face frequent drug shortages, excesses of unnecessary medications and potentially inappropriate international donations. To promote adherence to international recommendations and enable targeted requests for international drug donations, this paper describes a process using a public-health approach to create a site-specific pharmacy formulary in a resource-poor setting using the World Health Organization's (WHO) Model List of Essential Medicines ('Model List'). The study site was a Malawian-run non-profit private clinic serving over 3000 people annually. The organization focuses on providing community support for orphans from the HIV/AIDS crisis in sub-Saharan Africa. While using the Model List as a backbone, we incorporated the clinic's drug inventory, patient needs, clinician prescribing patterns, and the country's national drug list into the final formulary. After analyzing site-specific factors, we determined which WHO Model List therapeutic classes were necessary for the clinic to address in the final formulary. Of the drug products currently available in the inventory, 65.6% were expired, 29.8% of which were international donations. After removing expired medications from the inventory, seven Model List priority categories remained unaddressed by the clinic's initial inventory. Based on the results of a structured needs assessment, 54 products were selected for the final simplified formulary. Conscious selection of pharmaceuticals, resulting in a systematic formulary for drug distribution management, is critical so that a clinic can focus on procuring and prescribing the most needed medications. This selection process using the WHO Model List and a public-health approach to drug management could serve as a private clinic model for pharmaceutical optimization and targeted international drug donations in sub-Saharan Africa and other resource limited settings.
