Abstract

This study examines the determinants of Health Information Systems (HIS) usability, using a case study of Muhimbili National Hospital (MNH). In this study, we focus on human, organizational, and technological factors. The Human, Organization, and Technology-Fit (HOT-Fit) model guided this research. We utilize a mixed-methods research approach with a descriptive survey design and a sample of 109 respondents selected from the 1500 population at Muhimbili National Hospital through simple random and purposive sampling. Semi-structured interviews were used to gather qualitative data in order to delve further into the experiences and perspectives of MNH staff members, while structured questionnaires were used to collect quantitative data in order to evaluate various aspects of Health Information Systems (HIS) usability. The analysis of quantitative data was conducted by using descriptive statistics and multiple linear regression analysis, while qualitative data were analyzed through thematic analysis. The findings showed that human factors, such as education and training, significantly enhance HIS usability. Organizational factors, such as organizational structure, policies, and top management support, have a significant and positive impact on HIS usability. Technological factors, such as infrastructure reliability and system capabilities, also have a significant and positive impact on HIS usability. The study also revealed the interdependence of these factors, underscoring the significance of staff engagement and effective management practices. It is recommended that enhancing training with practical applications, strengthening organizational support, investing in robust infrastructure, implementing user feedback mechanisms, and promoting interdisciplinary collaboration could optimize HIS usability.
