Terminology Standards for Health Information Exchange in the times of SARS-Cov2 by Prof. Supten Sarbadhikari, @supten

To offer higher and value efficient affected person care, one must trade healthcare info. For this to occur seamlessly, there’s a dire want of Requirements that facilitate this interoperability.

A Commonplace denotes the power of two or extra techniques or elements to trade info (structural or syntactic interoperability) and to (meaningfully) use the data that has been exchanged (useful or semantic interoperability).

The EHR Requirements, 2nd version, had been notified by the Ministry of Well being and Household Welfare, Authorities of India (MoHFW) in December 2016.
Subsequently, to reinforce implementation of digital well being in India, the Nationwide Digital Well being Blueprint (NDHB) has been lastly notified, and it additionally mentions a minimal set of requirements for use. It tries to outline the requirements required for guaranteeing interoperability throughout the Nationwide Digital Well being Eco-system.

Additionally, now the Telemedicine Observe Pointers have been notified by the MoHFW and NITI Aayog.

Classes of Requirements for trade of Well being Info

The broad classes for Requirements talked about within the NDHB are these for Consent, (Scientific) Content material, Privateness and Safety, Affected person Security and Information High quality. At the moment for epidemiological functions, all international locations ship stories to the WHO utilizing the ICD classification system (present model is ICD-10, whereas ICD-11 has been formally launched final 12 months and can be relevant from January 2022). Nevertheless, for getting higher insights into the scientific information, SNOMED CT (a scientific terminology system) is the globally most popular commonplace and India has been a rustic member of SNOMED Worldwide since 2014. The fundamental variations of those two techniques are summarized under.

  • ICD (Worldwide Statistical Classification of Illnesses) codes, from the WHO, have restricted scope and granularity, summarizes and aggregates information into broad classes (for epidemiological functions), and are mono-hierarchical (Every code is grouped right into a single grouping)
    • No hyperlinks to physique websites or causes
    • Teams a number of scientific meanings  collectively utilizing a single code
    • Doesn’t at all times characterize enough element for scientific functions
  • SNOMED CT is broader in scope, extra granular, permits information to be grouped and aggregated in numerous methods (poly-hierarchical), and to be queried, basedon Relationships between the Ideas. Additionally, since it’s inherently logical, creating Scientific Resolution Assist Methods (CDSS) can be comparatively simpler with SNOMED-CT enabled techniques.

Presently mappings can be found from to SNOMED CT to ICD-10 and its numerous variations. Due to this fact, if any system is SNOMED CT enabled, it’s doable to report in accordance with ICD-10 or 11 as often is the statutory requirement for epidemiological and public well being functions.

Updating for SARS-Cov2

Now, with the world being gripped by a brand new Pandemic, the SDOs (Requirements Growth Organizations) have additionally equipped and give you pertinent requirements for this novel Corona virus or Covid-19 (Corona virus Illness 2019) or SARS-Cov2 (Extreme Acute Respiratory Syndrome Coronavirus-2). The World Well being Group (WHO) has named the syndrome brought on by this coronavirus “COVID-19”, and the Worldwide Committee on Taxonomy of Viruses (ICTV) has named the virus SARS-CoV-2.

The COVID-19 illness outbreak has been declared a public well being emergency of worldwide concern. The WHO has included it into the ICD system:

  • An emergency ICD-10 code of ‘U07.1 COVID-19, virus recognized’ is assigned to a illness analysis of COVID-19 confirmed by laboratory testing.
  • emergency ICD-10 code of ‘U07.2 COVID-19, virus not recognized’ is assigned to a scientific or epidemiological analysis of COVID-19 the place laboratory affirmation is inconclusive or not accessible.
  • Each U07.1 and U07.2 could also be used for mortality coding as reason for loss of life
  • In ICD-11, the code for the confirmed analysis of COVID-19 is RA01.0 and the code for the scientific analysis (suspected or possible) of COVID-19 is RA01.1.

A extra detailed breakup for ICD-10 is offered at:

SNOMED Worldwide has come out by inserting the idea beneath the dad or mum Human Coronavirus (Organism): Extreme acute respiratory syndrome coronavirus 2 (organism) – SCTID: 840533007

840533007 | Extreme acute respiratory syndrome coronavirus 2 (organism)| en   Extreme acute respiratory syndrome coronavirus 2 (organism)
en   2019-nCoV
en   Extreme acute respiratory syndrome coronavirus 2
en   SARS-CoV-2
en   2019 novel coronavirus

And, beneath Coronavirus an infection (Dysfunction): Illness brought on by extreme acute respiratory syndrome coronavirus 2 (dysfunction) – SCTID: 840539006

840539006 | Illness brought on by extreme acute respiratory syndrome coronavirus 2 (dysfunction) |  

en   Illness brought on by extreme acute respiratory syndrome coronavirus 2
en   COVID-19
en   Illness brought on by 2019 novel coronavirus
en   Illness brought on by 2019-nCoV
en   Illness brought on by extreme acute respiratory syndrome coronavirus 2 (dysfunction)

The Regenstrief Institute that develops the LOINC codes, is creating Particular Use codes in response to an pressing or emergent scenario. These codes are based mostly on the freshest info accessible on the time of their creation. They’ve undergone the traditional QA terminology course of. LOINC helps their use within the distinctive scenario that resulted of their fast creation. Nevertheless, bear in mind that downstream customers is probably not able to deal with prerelease codes till they’re revealed in an official launch. The rising codes for Covid-19 can be found at:


The pandemic of SARS-Cov2 is evolving, and, so are the Requirements associated to the trade of well being info due to the dysfunction and / or organism. As soon as the scenario stabilizes a bit, the unambiguity within the semantic trade of such info can even grow to be clear.
