Effect of Supplier Selection Practices on Availability of Essential Medicines in Private Pharmacies: A Case Study of Kicukiro District, Rwanda.
This study in Rwanda's Kicukiro District reveals that supplier selection practices, particularly quality standards and capacity, are strongly associated with the availability of essential medicines in private pharmacies, although the specific impact of supplier reliability is difficult to isolate due to its high correlation with quality standards.

In the quiet corners of a pharmacy, a complex chain of decisions determines whether a patient leaves with a life-saving pill or an empty hand. This chain begins long before a customer walks through the door, rooted in the choices pharmacy managers make about who they trust to supply their shelves. These choices involve three main considerations: whether a supplier delivers on time and answers quickly, whether the medicines they provide meet strict safety and quality rules, and whether the supplier has enough stock and money to keep the flow going. In many parts of the world, including Rwanda, the consistent presence of essential medicines depends heavily on these procurement decisions. When the supply chain falters, the result is not just an empty shelf, but a gap in care that can affect the health of entire communities. Understanding which of these supplier factors matters most is a critical step toward ensuring that the medicines people need are always there when they need them.
A recent study conducted in the Kicukiro District of Rwanda set out to untangle these relationships within the private pharmacy sector. Researchers visited 103 licensed private pharmacies, speaking with the pharmacists and staff members responsible for ordering and managing stock. They asked these professionals to rate their suppliers based on reliability, quality standards, and capacity, while simultaneously checking the actual shelves to see which of 25 essential medicines were in stock. The goal was to see if the way a pharmacy chose its suppliers directly influenced how often they ran out of critical drugs. The study focused on everyday essentials, ranging from common pain relievers and antibiotics to medicines for thyroid conditions and diabetes.
The investigation revealed a powerful connection between how pharmacies select their suppliers and the availability of medicines on their shelves. When the researchers looked at the data, they found that pharmacies which reported higher scores for supplier quality and supplier capacity also had significantly better stock levels. Specifically, the ability of a supplier to meet quality standards—ensuring products are authentic, properly labeled, and compliant with regulations—was the strongest predictor of whether medicines were available. Similarly, a supplier's capacity, meaning their ability to hold enough inventory and manage logistics effectively, also played a clear and positive role in keeping shelves stocked.
However, the story of supplier reliability was more complex. While pharmacies that praised their suppliers for being on-time and responsive also tended to have better stock, the statistical analysis showed that this factor did not stand out as an independent driver once quality and capacity were taken into account. This happened because reliability and quality standards were so closely linked in the real world that it was difficult to separate their individual effects; when a supplier is highly reliable, they are almost always also highly compliant with quality rules. Consequently, the study could not definitively say that reliability alone was the missing piece, but it did confirm that the combination of high quality and strong capacity is what truly keeps medicines available.
The researchers checked the actual shelves of the participating pharmacies and found that availability varied widely depending on the medicine. Some items, such as oral rehydration salts and the combination drug for malaria, were found in nearly every pharmacy, with availability rates reaching 99 percent. In contrast, other essential medicines, including certain thyroid and antidepressant medications, were missing from a significant number of stores, with some pharmacies reporting stock-outs that lasted up to eight days. The study suggests that the path to fixing these gaps lies in strengthening the systems that evaluate suppliers. By focusing on rigorous quality assurance and ensuring that suppliers have the financial and logistical capacity to deliver, pharmacy managers can create a more stable environment where essential medicines remain accessible to the public. The findings point toward a future where better supplier selection practices lead to fewer empty shelves and more consistent care for patients across the district.
