Abstract

The study assessed the impact of health information systems on COVID-19 vaccination coverage in Mwananyamala Municipality. Specifically focusing on; assessing the contribution of DHIS2 on improving COVID-19 vaccination data quality, evaluating the impact of DHIS2 on improving COVID-19 vaccination data utilization, examining the role of DHIS2 in supporting resource commitments towards COVID-19 and identifying specific challenges encountered in the implementation of DHIS2 for COVID-19 vaccination distribution and coverage. The study was theoretically guided by the Normalization Process. A sample size of 65 respondents was selected using systematic random sampling and purposive sampling techniques. Data was collected using interviews. Quantitative data analysis techniques were aided by SPSS version 27; where both descriptive and Multiple Linear Regression (MLR) analysis was done. The study found that DHIS2 significantly contributes to enhancing the quality of COVID-19 vaccination data, including attributes such as data availability, user-friendliness, accessibility, and visibility. DHIS2 has a positive influence on the utilization and implementation of COVID-19 vaccination data in program planning, decision making, clinical management, and cost control. Furthermore, the study revealed that DHIS2 facilitates increased commitment of resources to COVID-19 vaccination efforts. The study also revealed several constraints that hinder the full realization of DHIS2’s potential, including resource limitations, data set incompleteness, healthcare system weaknesses, lack of COVID-19 funding, healthcare accessibility barriers and vaccine hesitancy. The study concluded by recommending that health authorities and governments prioritise DHIS2 integration, policymakers develop supportive policies and stakeholders actively engage in DHIS2 implementations. Keywords: Vaccination, Vaccination Coverage, Health Information Systems, Overview of DHIS2
