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.

Leveraging FHIR and LOINC to Deliver CDS Hooks-based Clinical Workflows

Incorporating best practices for standards of care into clinical workflows is both critical and challenging. Clinicians recognize the need to have reliable, up-to-date clinical decision support embedded within their workflow; however, the siloed architecture of on-premise EHR installations and site-by-site customizations makes it burdensome for the clinical IT staff at each individual hospital to keep their own systems up-to-date with the latest best practices. Financially, the clock is ticking - The Centers for Medicaid and Medicare Services (CMS) already requires decision support tools to be consulted prior to placing certain orders.

Offering a cloud-based architecture, and taking a standards-based approach, Rimidi has been able to bridge the silos between individual healthcare systems and offer a single consolidated reference for clinical decision support. By leveraging LOINC, FHIR, and the CDS Hooks standard, all of which are widely supported by the Health IT industry, Rimidi is able to inject decision support advisories directly into workflows of any hospital and any EHR.

In this presentation, we will take a look 'under the hood' of Rimidi's clinical decision support engine, and explain how, by combining LOINC with FHIR and CDS Hooks, it does not have to be hard to have reliable, up-to-date decision support in your clinical workflows.

Parts are the LEGO bricks used to build LOINC terms. These reusable pieces have many other applications within LOINC, including those related to descriptions and name building, and also can be used to link to resources outside of LOINC, such as external ontologies. This session, suitable for both newcomers and experienced LOINCers, will teach you the purpose behind LOINC Parts and how you can take advantage of their capabilities.

FHIR and LOINC go together like chips and salsa! FHIR's standardized resources and API are the perfect delivery vehicle for clinical data coded with LOINC, the freely available international vocabulary standard for identifying health measurements, observations and documents. LOINC is now ubiquitous in health data systems worldwide and is an essential ingredient of system interoperability. In this session, we'll get acquainted with the basics of FHIR and tour the common FHIR resources where you can make use of LOINC coded health data. Many users are familiar with how LOINC is distributed in custom table formats and with LOINC-specific software (RELMA). In this session we will explore how LOINC content is also made available through Regenstrief's standardized API for LOINC that implements FHIR terminology services specifications. We'll demonstrate use of the CodeSystem, ValueSet, ConceptMap, and Questionnaire resources from FHIR.

Automated hierarchical crosswalk between LOINC Laboratory tests and SNOMED CT Measurements

It is known that the purpose of the Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) is to standardize the representation format of healthcare data. It has been adopted by the Health Data Sciences and Informatics (OHDSI) collaborative, a multi-stakeholder, to create open-source solutions that bring out the value of observational health data through large-scale analytics.

In the OMOP CDM, such ontologies as SNOMED CT and LOINC are used as Gold standards for the transformation of raw Observations and Measurements into the standardizes ones. Moreover, Regenstrief Institute and SNOMED International have formed a long-term collaborative relationship with the objective of developing coded content to support order entry and result reporting.

Material and methods: the LOINC-SNOMED collaborative has provided a mapping from LOINC Terms to SNOMED pre-coordinated concepts. Using this, we have built a hierarchical crosswalk that embeds more granular LOINC Laboratory tests into the SNOMED CT Hierarchy of Measurements. The approach is based on both sophisticated logic and an automatic match of common attribute combinations via SQL. Hierarchical links are represented by "Is a" relationship that implies that the LOINC Term semantically resides below the SNOMED CT concept.

Results: We have obtained more than 12,000 hierarchical links from the LOINC Laboratory Tests to SNOMED Measurements. This approach gives the opportunity to reproduce the automatic mapping with respect to every LOINC update.

Problem Concept Maps (ProMaps): Use of LOINC for Mitigation of Cognitive Load

Excess cognitive load is an unintended consequence of Electronic Health Record (EHR) implementation and a significant contributor to physician burnout. Cognitive load can be mitigated by providing automatic data summaries in a single screen. These automatic data summaries function as a clinical decision support tool providing a Problem Oriented View (POV), which is displayed on-the-fly using Problem Concept Maps (ProMaps). We have successfully built Problem Concept Maps using LOINC codes for laboratory results and RxNorm codes for medications. We will explain how ProMaps are built using a Modified Delphi technique on Google Drive to generate consensus among specialists at six academic medical centers.

The consensus method above was utilized to create numerous maps implemented at several medical centers across the country. Physician response has been very positive. We received NIH funding to study the effect of POV using ProMaps on physician workflows in a simulation environment. The POV allowed for faster and more accurate data retrieval and resulted in higher usability scores and lower cognitive load scores. All scores were statistically significant.

Problem Concept Maps integrate LOINC codes representing the variety of ways laboratory testing can be performed globally. Future maps will include codes for imaging tests. ProMaps implementations across EHR vendors provide real world evidence of how LOINC can be leveraged in achieving laboratory data interoperability. Our team will share some of the issues and challenges throughout our journey to assist others to better realize the value of LOINC in clinical decision support.

Considerations in the Utilization of LOINC in the Problem Concept Maps (PCM) Clinical Decision Support Tool

Problem Concept Maps (PCM) is a clinical decision support tool designed to improve physician EHR use, reduce cognitive burden, and ultimately improve patient care. PCM leverages LOINC maps to clinical problems to display a Problem Oriented View (POV) with respective laboratory test results (and radiology results in the future) in fostering efficiencies in the diagnostic process.

Development of the LOINC maps for global integration across EHR vendors will be discussed, including issues and challenges considered. Whether you are a laboratory professional or clinical informaticist building clinical decision support tools, rules or FHIR apps with LOINC, learn about needs with data encoded with LOINC in driving interoperability and quality implementations.

Occupational Health and LOINC: A Need for Standards

David and Rich from Enterprise Health, one of the leading companies for providing occupational health and compliance solutions, will discuss the state of coding standards (or in most cases the lack of them) in many segments of the occupational health industry, such as hearing conservation programs and the use of Audiometry testing (including equipment calibration records) to identify and monitor work-related hearing loss along with use of employee questionnaires and noise monitoring (area and personal) to assess noise exposure levels. They will discuss working with LOINC to start getting codes for some of these tests and measurements in place, including the recently added Audiometry Testing panel and codes.

Title To Be Determined

Many physicians and engineers have been using physiologic time series signals to build a new class of predictive algorithms in monitored patients. These physiologic times series are typically waveform of vital signs digitized at 100-500Hz. Alongside this extremely high density data, a numerical signal is generated every second 1Hz. For example, blood pressure a wave with a particular shape, with a maximum (systolic) and diastolic pressures. There are several vendors around generating waveform density signals. Several group are now developing ML-based engines based on those signals.

As a consequence, there is a growing need for interoperability of the input into those engines, and tagging LOINC codes to 1HZ and >100Hz signals would be of great help to those developing such analytics. The closest there exist right now is a LOINC code for moderate frequency output from a wearable signal such as Fitbit generate heart rate. Our problem is a lot richer and very different.
