Guiding Principles

The NDHM will be designed, developed, deployed, operated and maintained by the Government in accordance with the guiding principles as laid out in NDHB. The NDHM guiding principles are as follows:

Business Principles (Health Domain Principles)

  • NDHM will be wellness-centric and wellness-driven - Wellness centres and mobile screening teams will be strengthened through real-time access to personal health records.
  • NDHM will educate and empower individuals to avail a wide range of health and wellness services - Mass awareness and education will be promoted through use of appropriate platforms and a portfolio of Health Apps.
  • NDHM systems will be designed to be inclusive - Specialized systems will be designed to reach out to the “unconnected”, digitally illiterate, remote, hilly, and tribal areas.
  • NHDM will ensure security and privacy by design - A National Policy on Security of Health Systems and Privacy of Personal Health Records will be developed, in accordance with the PDP Bill 2019. All the building blocks that require handling personal health records will be designed to comply with such a policy at the outset. (How does NDHM ensure Information Security and Privacy ?)
  • NDHM will be designed to measure and display the performance and accountability of all health service providers - Real-time monitoring of performance of all health institutions and professionals against agreed KPIs will be done across service levels of the health sector and published.
  • NDHM will have a national footprint and will enable seamless portability across the country through a Health ID – Personal Health Identifier, with supporting blocks, including adoption of Health Information Standards will play a pivotal role in national portability.
  • The eco-system of NDHM will be built basing on the principle, “Think big, start small, scale fast” - NDHM will adopt a combination of strategies like taking a minimalistic approach for designing each building block, prioritizing and sequencing of the development/ launch of these blocks, and designing a technology architecture that can rapidly and agilely scale horizontally and vertically.

Technology Principles

  • NDHM will be developed by adopting India Enterprise Architecture Framework (IndEA) - The design of the building blocks of NDHM will adopt and conform to IndEA by default. All the design and development efforts will adopt the Agile IndEA Framework notified by MeitY.
  • All the building blocks and components of NDHM will conform to open standards, be interoperable and based on Open Source Software products and open source development - The policy on Open Standards and Open Source Software, notified by MeitY, GoI, will be adopted in designing of the building blocks and in all procurements. Interoperability will be inherent to all the building blocks.
  • Federated Architecture will be adopted in all aspects of NDHM - Only the identified Core Building Blocks will be developed and maintained centrally. All other building blocks will be designed to be operated in a federated model that factors regional, state-level and institution-level platforms and systems to function independently but in an interoperable manner. As defined in NDHM, the data will be federated and stored close to the point of generation.
  • NDHM will be an Open API-based ecosystem - All the building Blocks will be architected adopting the Open API Policy notified by MeitY, GoI and will share data as per standards as defined in NDHB. Security and Privacy will be built into the design and development of the APIs, which should be audited for security and privacy before deployment.
  • All major legacy systems will be assessed for conformance to NDHB principles and leveraged to the extent feasible - Compliance of legacy systems to the Blueprint principles and Agile IndEA principles will be assessed through an appropriately designed assessment tool to evaluate the current conformance and effort required to integrate them with NDHM. Only those legacy systems that cross the bar will be allowed to operate within the eco-system. However, the useful data about healthcare providers, labs, patients available in the legacy applications will be leveraged and utilized to the extent possible, leading to savings in time and effort in collecting such information again.
  • All the components, building blocks, registries, and artefacts of NDHM will be designed adopting a minimalistic approach - Easy, early, and collective adoption of the Blueprint by majority will be critical to its success. Hence every component of the Blueprint will be designed to be minimalistic.
  • All the registries and other master databases of NDHM will be built as Single Source of Truth on different aspects and backed by strong data governance - Rigid validation processes will be applied to all mandatory ‘fields’, clear ownership and responsibilities will be defined for all core databases and strong, dedicated data governance structures will be established at the State and Central levels.
