LOINC for Beginners

Jami Deckard

  • Jami Deckard, MS
    Regenstrief Institute

LOINC is the universal standard for identifying health measurements, observations, and documents. It is now ubiquitous in health data systems worldwide, and is an essential ingredient of system interoperability. This tutorial presents an overview of LOINC and its use around the world, discusses the LOINC concept model and data structures, and describes the resources available for implementing LOINC. If you are new(ish) to LOINC, this session should be your starting point.

LOINC Groups: A tool for data aggregation

Swapna Abhyankar

  • Swapna Abhyankar, MD
    Regenstrief Institute

Data aggregation is important for many purposes, but differences in granularity create challenges even when using standard terminologies. LOINC Groups provide a flexible, computable mechanism for rolling up LOINC terms to support aggregation. The Groups span a variety of domains, including laboratory, radiology, and clinical notes. This session will take an in-depth look at LOINC Groups as well as provide an overview of the online LOINC Groups Community Submissions portal and FHIR API-based access.

RELMA Part 1

Daniel Vreeman

  • Daniel Vreeman, PT, DPT, MS
    Regenstrief Institute

RELMA is the gold standard tool for mapping your local observation codes to LOINC. In Part 1, we’ll cover a high level roadmap of mapping with RELMA, how to setup and load your local terms into RELMA, and keys for mapping success with RELMA.

Mapping Local Panels to LOINC Panels

Swapna Abhyankar Jami Deckard

  • Swapna Abhyankar, MD
    Regenstrief Institute
  • Jami Deckard, MS
    Regenstrief Institute

In this session, we will cover the current best practices for mapping your local panels to LOINC panels. We will briefly explain how panels are modeled in LOINC and walk through the business rules for mapping, including required versus optional elements, mass versus substance term substitutions, and methodless terms versus codes with methods. We will also discuss the difference between panels and reports or clinical documents, making you an expert in mapping to these important terms.

LOINC 25 years: where we have been, where we are, and where we might go

Clem McDonald

  • Clem McDonald, MD
    National Library of Medicine

In the early ‘90s, laboratories and other clinical services began to deliver structured test results in HL7 V2 messages. No universal codes existed for the identifying the individual tests and measure in the messages. Each organization used their own local idiosyncratic test codes in OBX-3 to identify the content. This was survivable within the organization to the extent that each component of the organization used the same set of local codes. However, these local codes were not understandable by outside organizations. Therefore, between organizations, communication was all Babble. LOINC was created as a universal code system to enable across organization communication (interoperability). Clem McDonald will provide the history of its development and the general principles that guided it.

RELMA Part 2

Daniel Vreeman

  • Daniel Vreeman, PT, DPT, MS
    Regenstrief Institute

In Part 2 of mapping with RELMA series, we’ll dive deep into how to optimize the mapping process with RELMA, become a search syntax ninja, and how to set yourself up for success in the long run.

Local Terminology Management: The problem that doesn't take care of itself

David Baorto

  • David Baorto, MD, PhD
    Regenstrief Institute

Managing terminology across a regional health care system or even in a single health care facility can be a daunting task. Underlying local systems and codes are changing constantly, and at the same time LOINC and other standards are evolving. The speaker will present insights, examples, and pearls from 18 years of experience in terminology management for a large regional hospital system.

LHC Flowsheet on FHIR

Clem McDonald

  • Clem McDonald, MD
    National Library of Medicine

Motivated by the success of the Regenstrief medical record system, Lister Hill Center (LHC)/National Library of Medicine (NLM) researchers developed a tool to produce a clinical flowsheet with novel features. This workshop will present the LHC/NLM, open source, flowsheet app for delivering EHR data in a flowsheet format. The tool is a pure JavaScript. We will describe the template that controls the organization and behavior of the display. We will describe the NLM experience with the FHIR HAPI server and its performance with very large (>30K observation) records. We will also explain novel features including row collapsing (using equivalence classes and unit conversions), column collapsing into larger time windows, and a pixel map that shows where the mass of data lives.

Laboratory In Vitro Diagnostics (LIVD) LOINCs for Laboratory Professionals

Andrea Pitkus

  • Andrea Pitkus, PhD, MLS(ASCP)CM
    Independent

Learn about the recent LIVD Standard, designed to assist laboratory professionals with providing LOINC codes they can use to map to the laboratory test results corresponding to the IVD systems in their laboratories. Come walk through the standard features and review examples from IVD vendors demonstrating its use, scope, and benefits. We'll discuss the Excel and FHIR (Fast Healthcare Interoperability Resources) formats, and what's next for this valuable resource.
