The following is a brief final report of the NIEM Health Community of Interest (COI) under the Federal Health Architecture (FHA) Program of the Office of the National Coordinator for Health IT (ONC) from 2012 to September 2019. The FHA will sunset September 9th, 2019 leaving an opportunity for a new steward to enhance this work supporting future of health interoperability.
The value of NIEM lies in its ability to exchange information across multiple domains and platforms. The ability to exchange health information using NIEM enables non-clinical NIEM Domains to save lives.
The National Information Exchange Model (NIEM) is a framework for creating a common vocabulary by standardizing “data in motion” between disparate systems and domains. NIEM consists of 16 domains with 2 new domains – Housing Domain, Stewarded by the United States Department of Housing and Urban Development (HUD), and the Statistics Domain, stewarded by the US Census Bureau.
Although as a nation we have celebrated many accomplishments in Health information exchanges, these are focused on clinical exchanges where HL7 the predominant standard protocol. Overlooked are those in the NIEM community who require health information when responding to natural disasters, querying for beds in an ally’s country for a wounded warrior, preparing an inmate for re-entry into the community, or matching patients to a prescription at a pharmacy. It is safe to assume that the majority of the world outside of a health provider setting will not have access to a FHIR server or be able to exchange C-CCDAs.
NIEM Health attempts to solve this dilemma by mapping the health information exchange requirements among 2 or more exchange partners so that the data exchanged will be understood by both the clinical health IT participants and the NIEM IT participants. This type of interoperability has the power to save lives by:
In our time leading NIEM Health we have:
Existing NIEM Health elements must be aligned across domains and enhanced based on USCDI to be leveraged with existing HIE standards;
Health is a nationwide public matter that carries over into nearly every NIEM domain. Yet healthcare is sophisticated, involving multiple specialties and multiple health information exchange protocols. NIEM’s goal is to be simple. In the absence of a mapping between these sophisticated and simple realms, NIEM Domains have, over the years, defined many simple NIEM healthcare elements on their own - over 300 NIEM Health elements defined by over six domains, These have been defined to collect critical, yet tightly focused health information to meet the requirements of non-clinical scenarios (e.g., public health, emergency management, foster care records, etc.) But these existing elements often do not align with clinical health information standards and many are not even consistently coordinated across the multiple NIEM domains that define health-related elements.
This has happened because, while there are effective standards for clinician-to-clinician health information exchange, there is still a need for healthcare information exchange for scenarios that are just beyond the reach of the sophisticated world of health IT standards.
Historically, when NIEM Domains need to collect or exchange healthcare information, generally that information is not central to the mission of the domain and is collected from the healthcare world at the “edge” of the domain – often by reentering data scraped from printed sources. And similarly, from the healthcare IT world’s perspective, information that needs to transit from the clinical health information standards world out to a NIEM Domain, is transiting at the edge of the clinical world’s domain – often by printing out a record. So, from the perspective of both NIEM Domains and the Clinical Healthcare Domain enabling NIEM Health digital Information Exchange has been an edge-case that is not central to any of their missions. These edge cases are often cases of dire emergency when seconds count to save lives.
NIEM Health should focus on the exchange of healthcare information in non-traditional settings or “Edge Case Scenarios”
The nation has made great progress in EHR implementations. But what happens outside of these clinical to clinical transactions (hospitals, doctors offices, walk-in clinics, etc.). What happens when we involved police, firefighters and ambulances? What about triaging patients after a natural disaster? Querying for available beds when air lifting a wounded warrior from the battlefield? We coined these “Edge Case” scenarios and there is still a systematic breakdown in the ability for patient health information to be exchanged to the end user, …that is where the value of NIEM for Health is most likely.
We have identified many examples of NIEM health-related scenarios that require the ability to digitally interoperate between one or more purely NIEM Domains and the purely Clinical Healthcare Domain. Given the requirements of these many scenarios, how do we enable this interoperability between NIEM Domains and the Clinical Healthcare Domain?
Leveraging NIEM for Social Determinants of Health.
Determinants of health are the broad range of personal, social, economic and environmental factors that determine individual and population health. NIEM is unique in that information is collected and shared for Justice, Statistics, Housing and Human Services. It is our belief that many of the social, economic and physical environment metrics for an area are likely to be drawn from databases created and supported by agencies which are required to use NIEM for interoperability. The vision here is to work with others organizations to enable automating the integration of SDOH data from these NIEM-based sources into HL7-based clinical health records.
We recognize that in order to achieve nationwide health interoperability, we must look beyond the borders of provider-to-provider, clinical health information exchanges. NIEM Health, if executed correctly, has the power to save lives. It has been an honor and a privilege to have worked on this program and contribute in some small way to the improvement of our nation’s health and well-being.
