Assessment of the Impact of Inventory Management Systems on the Availability of Essential Medicines in Hospital Settings: Case of the Ndjili General Referral Hospital
Main Article Content
Abstract
The availability of essential medicines is a cornerstone of effective hospital care. In the Democratic Republic of Congo, many health facilities face frequent stockouts due to inadequate stock management. This study aimed to assess the impact of stock management systems on the availability of essential medicines at N’djili General Referral Hospital (HGR). A descriptive and analytical cross-sectional study was conducted from January to March 2025. Data were collected through semi-structured interviews, direct observation, and analysis of pharmaceutical management documents. The sample included pharmacy staff, logistics officers, and administrative managers. Data were analyzed using SPSS software (version 26). The average availability rate of essential medicines at HGR N’djili was 62%, below recommended standards. Stockouts primarily affected antibiotics and antimalarials. Major shortcomings were identified, including the absence of computerized tools, insufficient staff training, and poor planning. A strong correlation was found between effective stock management practices and medicine availability (r = 0.81; p < 0.01). Weaknesses in the stock management system negatively affect the regular supply of essential medicines. The study recommends implementing a computerized inventory management system, continuous training for staff, and improved logistical coordination to enhance medicine availability and service delivery quality.
