ABDM Milestone M2: Enabling Digital Health Record Sharing with HIP Services

Details

ABDM is transforming healthcare delivery in India. After Milestone M1 established ABHA IDs, M2 focuses on enabling digital health record sharing via HIP services. The goal is to allow patient data—such as lab results, prescriptions, and discharge summaries—to flow seamlessly across hospitals, labs, and clinics using standardized methods. Key technical requirements for M2 include: 1. **Minimum HI Types:** Compliance requires every HIP to support at least 7 Health Information (HI) types (e.g., Prescriptions, Lab Reports). This ensures the platform is a comprehensive exchange system. 2. **Standardization:** ABDM mandates using international standards: **SNOMED CT** for unique coding of diagnoses and procedures, and **LOINC** for lab tests and clinical measurements. Together, these ensure data consistency and interoperability. 3. **Data Packaging:** The coded data must be packaged into an **FHIR Bundle**. FHIR is a modern standard that organizes data into resources (Patient, Observation) for secure transmission, making the record machine-readable. 4. **Security:** Before sharing, data must be encrypted using **FEDLIS CLI** (Federated Data Layer Interface Service). This ensures confidentiality and integrity, guaranteeing access only by authorized parties with patient consent. M2 is crucial as it gives patients control over their records and provides a backbone for seamless information exchange among providers.
