A distributed healthcare network system stores intervention, context, and communication rules in databases, defining responses to patient-related events. Context includes factual circumstances tied to the patient. The system constructs a distributed ledger for each patient, incorporating their profile, therapeutic events, and context indicators based on predefined rules. Interventions are selected according to patient context and communicated to relevant network nodes, with records added to the ledger. AI models trained on patient data help identify subtle scenarios from context indicators and suggest alternative actions. Intervention rules rely on fixed thresholds and AI-driven analysis to determine appropriate responses. The ledger, distributed across the network, ensures transparency, enhances communication among patients, providers, and payers, and streamlines healthcare transactions. This method enables efficient decision-making, ensures accurate documentation, and improves healthcare coordination by maintaining an immutable, accessible record of patient interactions, interventions, and contextual factors.
