The study examined the adoption of digital health technologies to enhance operational efficiency at the National Health Insurance Authority (NHIA) in Southeast Nigeria. The broad objective of this study was to determine how the integration of digital health technologies can enhance operational efficiency at the National Health Insurance Authority (NHIA). The study adopted a cross-sectional survey design. Quantitative data were collected through a structured questionnaire from 408 respondents across selected NHIA provider health facilities, comprising healthcare professionals (clinical and non-clinical staff). Descriptive statistics were analysed using simple percentages and charts, while the Partial Least Squares - Structural Equation Modeling (PLS-SEM) was deployed to test the hypothesized relationships between the study variables with the aid of SmartPLS 4.1 software, ensuring reliability (Cronbach’s α > 0.7), convergent, and discriminant validity. The findings revealed that digital health technology adoption proxies of electronic health records and electronic claims management systems positively and significantly influence operational efficiency dimensions of patient data accuracy, and process optimisation. The study recommends continuous investment in digital health infrastructure, workforce training, and supportive policy frameworks to institutionalize technology-driven efficiency within NHIA operations. In conclusion, adopting digital health technology presents a sustainable pathway toward achieving transparency, accountability, and optimal performance in Nigeria’s health insurance system.
