Regenstrief and SNOMED International broaden collaboration to facilitate interoperability nationally and globally by linking LOINC and SNOMED CT

Laboratory terms are initial focus of standardized terminology initiative

2023-10-16

(Press-News.org) INDIANAPOLIS, US and LONDON, UK -- With the goal of facilitating broader interoperability of health data around the globe to enhance and improve the delivery of healthcare, LOINC® from Regenstrief and SNOMED International have commenced generation of The LOINC Ontology: A LOINC and SNOMED CT interoperability solution.

The LOINC Ontology supports providers and users who implement different combinations of SNOMED CT and LOINC in health information systems and allows them to meet clinical and regulatory requirements in a single solution. Linked together in a complementary way, SNOMED CT provides the computable framework and LOINC provides laboratory and pathology content in an understood format to countries who do not currently use LOINC.

This standardized terminology initiative to facilitate health information exchange provides new opportunities for growth of LOINC and SNOMED adoption and appreciably improves interoperability between the two standards, which serve an intersecting group of global implementers.

The LOINC Ontology is fully owned by Regenstrief Institute. It will be made available without charge under the existing LOINC royalty free license. SNOMED International members and users will be able to work with LOINC in the same format they already use for SNOMED CT.

Each organization retains editorial control of its respective standard.

To date, more than 24,000 LOINC terms are included in the LOINC ontology preview which will be published in the last quarter of the 2023 calendar year for review and feedback.

“The LOINC Ontology, a LOINC and SNOMED CT interoperability solution, is novel and transformative in providing clinical observation content in an integrated format and accelerates interoperability and supports stakeholders with meeting clinical, regulatory and administrative requirements,” said Marjorie Rallins, DPM, M.S., executive director of LOINC and Health Data Standards at Regenstrief.

LOINC, short for Logical Observation Identifiers Names and Codes, is a worldwide standard, used in 193 countries and available in 20 languages, for identifying health measurements, observations and documents enabling the identification, exchange and collection of data across health systems. Created and maintained at Regenstrief Institute, the system is free to users.

"Significant commitment and collaboration has been invested by both teams to produce the LOINC ontology preview,” SNOMED International CEO, Don Sweete shared. Sweete further elaborated, “This serves as an excellent illustration of how we have leveraged our mutual expertise to further the goal of interoperability for implementers globally.”

Owned and governed by 48 global Members, SNOMED International is a not-for-profit organization that is charged with setting global standards for health terminology, a critical element of safe and effective healthcare. SNOMED CT is a comprehensive, multilingual healthcare terminology created for use by healthcare professionals to capture the care of individuals in an electronic health record and facilitate sharing, decision support and analytics, to support safe and effective health information exchange.

The two organizations signed a milestone collaborative agreement in 2022 which lay the foundation for creation of the LOINC extension of SNOMED CT. Teams from both organizations working on the extension will meet at the upcoming LOINC Conference and at the SNOMED CT Expo, both to be held in Atlanta, Georgia later this year.

The 2022 agreement extended a relationship, inaugurated in 2013, which linked the clinical semantics of SNOMED to LOINC observational concepts enabling the identification, exchange and collection of data across health systems. The COVID-19 pandemic highlighted and emphasized the importance of coordinated standards to support interoperability of health data.

A powerful new tool in the fight against one of the deadliest cancers

2023-10-16

Osaka, Japan – Pancreatic ductal adenocarcinoma (PDAC) is one of the deadliest cancers worldwide, with a 5-year survival rate of less than 10%. Many PDAC tumors in early stage go undetected because they are not found using conventional imaging methods, including fluorodeoxyglucose positron emission tomography (PET) scans. To more efficiently combat this pancreatic cancer, a team led by researchers at Osaka University is combining diagnostic and therapeutic procedures into a single integrated process: ‘theranostics’. In an article recently published in Journal of Nuclear Medicine, the team has developed a ‘radio-theranostics’ strategy that uses a new ...

Holy immunity! Bat genes key against COVID, cancer

2023-10-16

Bats have acquired remarkable traits throughout their evolution. They’re the only mammals that can fly, and they live much longer than other animals their size. But perhaps most impressive is their robust immune system. It protects bats from viruses that wreak havoc in humans, like COVID-19 or Ebola. It also keeps bats relatively cancer-free. How? According to Cold Spring Harbor Laboratory (CSHL) scientists, it’s all in the genes. Using samples collected in Belize with Nancy Simmons from the American Museum of Natural History, CSHL Professors W. Richard McCombie and Adam ...

Novel enzyme family could provide insights into bacterial pathogenicity

2023-10-16

Gram-negative bacteria cause a variety of infectious diseases in plants and animals alike. Outbreaks of Salmonella and E. coli infections often make headlines due to their severity, and people have to resort to allopathic as well as natural remedies, increasing the burden on the healthcare system. While antibiotics offer an effective solution against bacterial infections, the increasing incidence of antibiotic-resistant bacteria have prompted researchers to identify other possible treatments against these infections. With technological advances and modern medicine, researchers are looking into the possibility of disrupting the pathogenicity of the bacteria ...

National Poll: Parents of elementary-aged children may engage in more helicopter parenting than they think

2023-10-16

ANN ARBOR, Mich. – As they grow, children start doing certain activities without their parents watching over them, including trick-or-treating with friends, staying home alone or biking to a friend’s house. And while most parents agree that kids benefit from opportunities to be independent, they may be engaging in more “helicopter parenting” than they realize, suggests a new University of Michigan Health C.S. Mott Children’s Hospital National Poll on Children’s Health. “There’s a sizable gap between parent attitudes about promoting children’s independence and what they actually allow or encourage ...

Local retail outlets for legal marijuana may be associated with alcohol co-use among high school students: Study

2023-10-16

PISCATAWAY, NJ—Given the increasing trend toward legalizing marijuana in many states, there is growing concern that underage youth may find the drug easier to access. In fact, a recent study reported in the Journal of Studies on Alcohol and Drugs suggests that in areas with local retail availability of legalized marijuana, high school students are more likely to use marijuana and alcohol together, as well as alcohol alone. “Greater retail availability may ‘normalize’ marijuana use for young people, even if they are unable to purchase marijuana directly from retail businesses, and retail sales may introduce greater access through social ...
