MiMIAT Health is a patient-anchored data infrastructure for chronic disease management. Through a portable health data wallet, patients unify time-stamped Patient-Generated Health Data and progressively add medical device data and clinical records, turning fragmented inputs into longitudinal Real-World Data (RWD) that can be shared across healthcare providers and geographies. Care teams receive real-time data and clinician-ready summaries to flag anomalies early, stratify risk, and track treatment effectiveness, with an upcoming AI-assisted clinical layer that summarizes the patient’s longitudinal record for faster clinical review.
