The Ayushman Bharat Digital Mission (ABDM) relies on robust registries to manage and integrate healthcare providers and facilities into its digital framework. The Healthcare Professionals Registry (HPR) serves as a comprehensive, centralized database of all healthcare professionals operating in India. This registry is inclusive, encompassing practitioners of both modern medicine and traditional systems of medicine, ensuring a broad representation of the healthcare workforce. Its function is vital for verifying credentials and enabling seamless connection and identification within the digital health ecosystem. Complementing the HPR is the Health Facility Registry (HFR). This registry acts as a master list of all healthcare facilities across the nation, whether they are public or private entities, including hospitals, clinics, diagnostic centers, and pharmacies. By enrolling in the HFR, these facilities become integrated into the national digital health network, enabling them to participate in and benefit from the ABDM services. Together, the HPR and HFR form essential pillars for the structured and organized functioning of the digital health infrastructure.
