HHS Launches Web Site for Medical Responses to Radiation Emergencies

[Editor's Note: This Technical Note is a reprint of an announcement published on NLM-Tox-Enviro-Health-L, an e-mail announcement list available from the NLM Division of Specialized Information Services. To subscribe to this list, please see the NLM-TOX-ENVIRO-HEALTH-L Join, Leave, or Change Options page.]

The Department of Health and Human Services has developed its first comprehensive Web site to assist health care professionals, primarily physicians, who may have to provide medical care during a radiation mass casualty incident.
[link removed] http://www.hhs.gov/news/press/2007pres/20070308.html

Radiation Event Medical Management (REMM) provides easy to follow algorithms for diagnosis and management of radiation contamination and exposure, guidance for the use of radiation countermeasures, and a variety of other features to facilitate medical responses.

Guidance on diagnosis and treatment will help health care providers by describing:

• types of radiation emergencies they may face
• initial medical actions at the incident site and or medical facility
• specific issues that apply to care in radiation mass casualty events.

Critical information is presented in a format that will quickly and efficiently orient and guide health care providers during a potential mass casualty radiation event. Federal, state and local medical response teams will be able to download REMM files to computers so that the documents are available without internet access. Users can also register for automatic e-mail updates whenever key material is changed or added to REMM.

Future plans include formatting REMM for use on Personal Digital Assistant (PDA) devices, additional multimedia graphics, and more topic areas such as follow-up patient care.

Subject matter experts from the HHS Office of the Assistant Secretary for Preparedness and Response (ASPR), the National Institutes of Health's National Cancer Institute (NCI), the National Library of Medicine (NLM), and the Centers for Disease Control and Prevention (CDC) collaborated on the content for REMM. HHS teamed with NLM's Division of Specialized Information Services to develop the site.

More specific information about this update can be found by selecting the "LactMed 3/2007" link at //toxnet.nlm.nih.gov/html/toxnet_update.html

LactMed is part of the NLM Toxicology Data Network (TOXNET®). It is a peer-reviewed and fully referenced database of drugs to which breastfeeding mothers may be exposed. LactMed includes information on the levels of such substances in breast milk and infant blood, and the possible adverse effects in the nursing infant. It provides statements of the American Academy of Pediatrics concerning a drug's compatibility with breastfeeding and suggested therapeutic alternatives to those drugs where appropriate.

NLM® Becomes Charter Member of New International SNOMED SDO®

On April 26, 2007, Mike Leavitt, Secretary of the U.S. Department of Health and Human Services (HHS), [link removed] announced that HHS is one of nine charter members of the new International Health Terminology Standards Development Organisation (IHTSDO® or SNOMED SDO), which has acquired SNOMED Clinical Terms (SNOMED CT®) from the College of American Pathologists (CAP). NLM represents HHS and the U.S. in the new organization and will continue to distribute SNOMED CT through its Unified Medical Language System® (UMLS®) Metathesaurus®. NLM will also make SNOMED CT available in its native format as required by the IHTSDO. Uniform international license terms for SNOMED CT will replace the U.S.-wide license terms NLM negotiated with the CAP in 2003, giving U.S. users broader rights to distribute derivative products internationally. The new license terms have been incorporated into the License for Use of the UMLS Metathesaurus. Existing UMLS licensees MUST review and accept the revised UMLS license online by May 15, 2007 in order to retain uninterrupted access to the UMLS Knowledge Source Server and related resources. Obtaining a UMLS license provides access to the UMLS Metathesaurus and other vocabulary resources including SNOMED CT files in their native format (effective May 15, 2007), RxNorm files in their native format, mapping files, UMLS-enriched subsets of specific vocabularies, etc.

• Update an EXISTING UMLS license
• Establish a NEW license

Impact on MEDLINE®/PubMed® from the PubMed Central® Back Issue Digitization Project

As of April 2007 under the PubMed Central Back Issue Digitization Project, the National Library of Medicine® (NLM®) has digitized nearly 40 journals back to the first volume for each title and has deposited the full text contents in PubMed Central (PMC). Publishers of those titles continue to deposit full text content for current material. This project, funded in part by the Wellcome Trust in the United Kingdom, has yielded the creation of over 70,000 "new" citations, including author abstracts when available, all of which have now been added to PubMed. About 38,000 are from issues that predate 1966 as the date of publication; some date to the late 1800's (e.g., Journal of Anatomy and Physiology). About 32,000 are from issues published from 1966 forward. These consist of issues that predate when the title was selected for indexing (e.g., Texas Heart Institute Journal) as well as those that belong to journals which were or are selectively indexed for MEDLINE (e.g., Plant Physiology, and Proceedings of the National Academy of Sciences).

These 70,000 citations were derived from the PMC data which underwent quality control review. The citations were then moved to the internal Data Creation and Maintenance System (DCMS) which is used by NLM for the MEDLINE citation workflow and from which NLM exports the information to PubMed and journal citation data licensees. These citations are not indexed with MeSH. At the completion of this project, all added citations will carry the citation status label of [PubMed]. While the project is on-going, some post-1965 citations may be held for further review to ensure that the data entry conventions are in line with the general MEDLINE format. These citations would have either [PubMed — in process] or [PubMed — as supplied by publisher], until processing is completed.

Another aspect of this digitization project is adding author abstracts from articles where the equivalent, previously existing MEDLINE/PubMed citation does not have an author abstract. An author abstract is one written by the author(s) and published as part of the article. Approximately 41,000 new abstracts have been added from the group of PMC journals for which full back issues have been completed. These additional abstracts increase text word access points especially for citations originally created for MEDLINE prior to 1975 when abstracts were not routinely included.

This process of supplementing PubMed with both new citations and new author abstracts is now a standard procedure when a PMC journal's back issue digitization is completed.
