DIGITAL SUPPLY CHAIN MONITORING ON VACCINE LOGISTICS PERFORMANCE IN ZARIA LOCAL GOVERNMENT AREA

Abstract

Efficient vaccine delivery is a critical public health challenge in developing countries like Nigeria, where preventable diseases persist. This study posits that digital supply chain monitoring significantly improves vaccine logistics performance, a hypothesis tested in Zaria Local Government Area, Kaduna State. Data from 110 healthcare personnel indicate that digital tools such as the Electronic Logistics Management Information System (eLMIS), mobile reporting platforms, and cloud-based monitoring systems are moderately to highly adopted, with 72–77% reporting use. Importantly, 77–84% observed improvements in vaccine logistics performance directly attributed to these digital systems, specifically in stock availability, cold chain integrity, timely delivery, and reduction of vaccine wastage. Chi-square tests confirm a statistically significant relationship (p < 0.05) between digital monitoring and key logistics outcomes, supporting the rejection of the null hypothesis. These results underscore the central argument: digital monitoring systems are essential for the efficient and reliable delivery of vaccines in resource-limited settings, though infrastructure and power challenges remain. Strengthening digital system adoption, staff capability, and infrastructure is vital for optimizing vaccine supply chains at the local government level.
