In Nigeria, while digital health interventions have been widely introduced, disparities in maturity and effectiveness are evident across different states. This study comprehensively assesses digital health maturity across ten Nigerian states, leveraging the Global Digital Health Index (GDHI) framework and the UN Foundation/ICT4SOML maturity model. Employing a mixed-methods approach that includes key informant interviews, document reviews, and quantitative scoring, the analysis evaluates seven core domains: leadership and governance, strategy and investment, legislation and compliance, standards and interoperability, infrastructure, workforce, and services and applications. The analysis also situates surveyed states along a maturity spectrum from experimentation to mainstreaming.\nFindings reveal substantial variations in digital health readiness among the ten states. Lagos emerged as the most advanced, demonstrating robust governance structures, interoperability initiatives, and strategic investments in ICT infrastructure. In contrast, states like Gombe, Niger, Bauchi, Sokoto, Borno, Nasarawa and Yobe were the least matured, hindered by weak workforce capacity, poor infrastructure, and a lack of standardized interoperability. The assessment further identifies heavy reliance on donor-driven projects, limited state ownership, and fragmented governance as key barriers to sustainable digital health implementation.\nTo address these gaps, the study recommends establishing a National Digital Health Observatory for benchmarking and peer learning, alongside targeted state-level capacity building and infrastructure investments. The findings highlight the urgent need for stronger political commitment, structured governance, and the domestication of national digital health policies at the sub-national level. By mapping states on a digital health maturity spectrum, this study offers a clear framework for targeted interventions, optimized resource allocation, and accelerated progress toward a resilient, interoperable digital health ecosystem across Nigeria’s states.\nCompeting Interest Statement\nThe authors have declared no competing interest.\nFunding Statement\nYes\nAuthor Declarations\nI confirm all relevant ethical guidelines have been followed, and any necessary IRB and/or ethics committee approvals have been obtained.\nYes\nThe details of the IRB/oversight body that provided approval or exemption for the research described are given below:\nEthical approval was obtained from the National Health Research Ethics Committee at the Federal Ministry of Health (FMOH).\nI confirm that all necessary patient/participant consent has been obtained and the appropriate institutional forms have been archived, and that any patient/participant/sample identifiers included were not known to anyone (e.g., hospital staff, patients or participants themselves) outside the research group so cannot be used to identify individuals.\nYes\nI understand that all clinical trials and any other prospective interventional studies must be registered with an ICMJE-approved registry, such as ClinicalTrials.gov.
