Integrating Information Systems Success, Institutional, and Resource Dependence Theories for Blockchain-Based Health Interoperability in LMICs
Main Article Content
Abstract
Digital health interoperability in devolved public health systems is constrained by technical, organisational, and systemic factors that current research treats as competing rather than complementary diagnoses. This paper asks which theoretical lens should govern a given readiness question, and answers through a four-step theoretical conceptual synthesis: selecting five established lenses, the DeLone and McLean Information Systems Success Model, the Blockchain Trilemma, the Parkerian Hexad, Institutional Theory, and Resource Dependence Theory; constructing an integrating structure; analysing tension and complementarity between lenses; and illustrating the resulting framework against a real governance context. Readiness is defined as the joint sufficiency of a health system's technical capacity, organisational legitimacy, and source-system quality to support a blockchain interoperability layer. The five lenses are organised along three readiness dimensions: technical, organisational, and systemic and applied to Kenya's devolved health system, including county-level evidence from Kisumu, drawing on the Constitution of Kenya (2010), the Digital Health Act (2023), the Kenya Health Information Systems Interoperability Framework (2020), the Data Protection Act (2019), and published accounts of electronic medical record fragmentation. Benchmarked against the WHO-ITU National eHealth Strategy Toolkit, the framework is shown to add diagnostic precision that a single-lens or purely strategic instrument does not supply. We conclude that treating readiness as one undifferentiated construct risks misdiagnosing which intervention a context actually needs, and recommend that certification regimes, research instruments, and technical-assistance programmes test technical, organisational, and systemic readiness separately rather than assuming the three co-vary.
