Inventory Management Performance for Tracer Medicines in Public Health Facilities of Southwest Shewa Zone Oromia Region, Ethiopia: A mixed study.

Introduction: Tracer medicines are medicines that must be available in sufficient quantities at all times to satisfy the priority health care needs of the population. Inventory mismanagement of these medicines poses significant challenges to public health systems, especially in countries like Ethiopia, where access to healthcare services is already limited. Objective: This study aims to assess inventory management performance for tracer medicines at public health facilities of the southwest Shewa zone, Oromia region, Ethiopia. Method: Concurrent triangulation mixed-method study was conducted from 1 to 30 June 2022. The quantitative data were collected using interviewer-administered semistructured questionnaires and observational checklists. The qualitative data were gathered through in-depth interviews with key informants. The quantitative data were analyzed using the SPSS version 26 and Excel spreadsheet version 16. We calculated the stock-out rate, inventory accuracy rate, percentage of facilities that fulfill appropriate storage conditions, percentage of facilities that submitted reports on time, and received the exact quantity of drugs they ordered. Qualitative data were analyzed manually using the thematic content analysis technique. Results: The inventory accuracy rate for tracer medicines was 76% for hospitals and 72.5% for health centers. The overall mean stock-out rate was 24.99%. Bin card updating practice was 93.3%, and only 25% health facilities met the acceptable storage conditions criteria. Among submitted reports, 88.8% were timely reported, 72.2% were accurate, and 75% were complete. Inventory management challenges include a shortage of supplies from the supplier and in the market, price inflation, inadequate training, lack of supportive supervision, insufficient IT and storage infrastructures, lack of communication, and budget constraints. Conclusion: From this finding, we concluded that facilities' report quality, inventory record accuracy, storage conditions, and logistics management information system needs improvements. Therefore, Ministry of Health, assessed facilities and Ethiopian pharmaceuticals Supply Services should take measures to improve them.
