The National Library of Medicine, the world’s largest medical library and a component of the National Institutes of Health (NIH), is pleased to announce the launch of its new YouTube channel! YouTube is a free video-sharing Web site, created in February 2005, on which users can upload, view and share videos. Unregistered users may watch videos, and registered users may upload an unlimited number of videos.
The NLM YouTube channel will post a variety of videos on topics from database training, NLM exhibitions (like an overview of the new Native Voices: Native Peoples’ Concepts of Health and Illness), Public Service Announcements, lectures and more. Interested parties can subscribe to be notified whenever new content is posted on the NLM channel. The NLM site also features links to NIH YouTube channels and other federal health resources.
The RxNorm standard clinical drug vocabulary produced by the National Library of Medicine (NLM) now contains more accurate and complete connections between National Drug Codes (NDCs) and standard nonproprietary names of medications recommended for use in electronic health records (EHRs). NLM is the world’s largest medical library and a component of the National Institutes of Health. It also includes, for the first time, the complete set of NDCs from Thomson Reuters’ Red Book, a drug database widely used in the health care industry.
NDCs are product identifiers assigned by manufacturers and packagers of drugs in the United States. They are published on medication labels and packages and are often used in pharmacy inventory control and in dispensing and billing for drugs. If a single manufacturer issues the same medication in packages of different sizes (25 tablets, 50 tablets, etc.), each size has a different NDC. If more than one manufacturer produces the same medication, each assigns different NDCs. In contrast, the RxNorm vocabulary creates standard names and identifiers for the combinations of ingredients, strengths, and dose forms (such as Aspirin 325 MG Oral Tablet) that exist in drugs marketed in the United States. This is the information doctors typically include when they write a prescription because they often can’t know the specific product that will be used to fill it. All medication products that contain the same active ingredients, the same strengths, and the same dose forms have the same RxNorm standard name. This standard name is connected to other information in RxNorm that can be used within EHR systems to improve patient safety.
Accurate and complete connections between NDC product codes and RxNorm standard names and identifiers have many potential uses within an individual patient’s EHR. These include the use of an NDC on a medicine bottle to speed standard data entry or to trigger an alert written in the RxNorm standard that could prevent a medication error. At present, there is no single source that contains the NDCs for all medications currently marketed in the United States. RxNorm has included NDCs provided by the Food and Drug Administration, the Department of Veterans Affairs, and the Multum and Gold Standard drug information sources for a number of years. Starting with the Feb. 7, 2011 release, RxNorm included a revised, filtered version of the NDC data that segregates obsolete NDCs from those currently in the marketplace. It also included First DataBank’s set of NDCs. Since August of 2011, it has included the NDCs from Red Book. Other useful data that Red Book is providing to RxNorm includes better linkages between branded drugs and their NDCs, information about whether or not drugs are still on the market, and Drug Enforcement Agency Class for controlled drugs. This additional information is instrumental in the production of the Current Prescribable Subset of RxNorm.
In a recently published study sponsored by the Centers for Medicare & Medicaid Services and performed by the RAND Corporation and others, RxNorm was found to have entries for essentially all of the drugs in a sample of 19,743 ambulatory e-prescriptions (electronic prescriptions for patients seen in clinics or physician offices). Some e-prescriptions in the study sample failed to match automatically to an NDC in RxNorm, however. A more complete set of NDCs is likely to eliminate this gap.

United States Surgeon General Dr. Regina Benjamin today declared Thanksgiving 2011 as the nation’s eighth annual “Family Health History Day,” when families can share information by using the My Family Health Portrait website to gather their family’s health history in one place. My Family Health Portrait is secure, free and takes about 20 minutes to create your unique family health portrait. It is available in English, Spanish, Portuguese, and Italian. Information can be shared with other family members who may not be home for Thanksgiving. They can build on your Family Health Portrait by adding their health information and can choose to share with you.
When you complete the questions, the website creates a personalized “family health tree” that can be saved to your home computer. From there, families may update the information at any time. Your information remains private. The federal website does not retain the information once the tool has been used to assemble it. Prepare for a Thanksgiving Day conversation by making a list of your relatives including your parents, grandparents, brothers, sisters, and cousins. Because some health conditions skip generations, be sure to talk to your older relatives who may know additional family history. Offering your doctor, physician assistant, or nurse practitioner your family health history can enable them to recommend specific tests or treatment plans to prevent or delay disease.
To mark World AIDS Day 2011 (December 1), a redesigned AIDSinfo Web site has been released, along with the Spanish-language infoSIDA. These sister sites offer federally approved information on HIV treatment and research, including medical practice guidelines and treatment and prevention research studies, to health care providers, researchers, people affected by HIV/AIDS, and the interested public. Information is available in both English and Spanish. AIDSinfo and infoSIDA are services of the US Department of Health and Human Services (HHS), managed by the National Library of Medicine (NLM). NLM is the world’s largest medical library and a component of the National Institutes of Health (NIH).
Redesign of the sites was based on research on user needs and behaviors and focused on reorganization of content and improved navigation to make information easier to find. Changes to the sites include:
- Reorganizing content logically into six main categories, including new categories for Education Materials and Mobile Resources and Tools.
- Creating a home page design that gives users a snapshot of the entire Web site, direct access to all site content, and the ability to search for information without having to click away from the home page.
- Improving navigation to reduce the number of clicks necessary to access information anywhere on the sites.
- Providing links to resources such as mobile applications and social media tools (including Facebook and Twitter) throughout the sites to make them accessible from any page.
- Creating a distinct Web address for infoSIDA-http://infosida.nih.gov/ to make it easier for users to bookmark and for search engines to index infoSIDA.

The National Library of Medicine, a component of the National Institutes of Health, celebrates a crucial turning point in its history with a new Web exhibition, “Building a National Medical Library on a Shoestring: 1872, the First Year.”
The exhibition focuses on the dramatic 1872 change in the library’s mission. Founded in 1836 as the office library for the Army Surgeon General, the Library came under the stewardship of Army Major John Shaw Billings in 1865. Seven years later, the Library embarked on a venture to acquire the most complete set possible of medical books and journals. Billings and his work set the course for the Library’s identity today as the world’s largest medical library.
The core of the exhibition is found in the stories, difficulties, and situations that Billings encountered as he began building a comprehensive collection as quickly and frugally as possible. The exhibition also shows the Library’s early years, exploring the practical uses that the limited collection then supported. Included is a full bibliography of published materials by and about John Shaw Billings, including articles and pamphlets, reports, books and monographs, and speeches.
Despite persistent racial and ethnic gaps in health care and health status, awareness of such disparities remains low among the general public. Much work remains to be done to better inform the U.S. population of health conditions that disproportionately impact specific racial and ethnic minority groups, according to an OMH survey conducted by NORC at the University of Chicago. The survey found:
- Fewer than two-thirds of Americans are aware of racial and ethnic health disparities;
- Awareness of racial and ethnic health disparities generally increases with education;
- Awareness of racial and ethnic health care access disparities is increasing, but remains low;
- Awareness of racial and ethnic disparities for key health status indicators and diseases remains low;
- Awareness of racial and ethnic health disparities remains low even among disproportionately affected minority groups;
- African Americans are more aware of racial and ethnic disparities;
- Awareness of racial and ethnic health disparities impacting Asian Americans/Pacific Islanders remains very low; and
- Public familiarity with important national health disparities reports and awareness campaigns is generally low.
The article about the OMH/NORC survey and its web supplements (General Population Questionnaire; Creating an Awareness Index) are available on the Health Affairs website. In addition, copies of the Study Brief and 2010 General Population Toplines are available on the Office of Minority Health website.
On October 31, 2011, the Department of Health and Human Services (HHS) released final standards to more consistently measure race, ethnicity, sex, primary language, and disability status, thereby improving our ability to highlight disparities in health status and target interventions to reduce these disparities.
The Affordable Care Act requires new standards for the collection and reporting of health care information based on race, ethnicity, sex, and primary language. Making data standards consistent will help identify the significant health differences that often exist between and within ethnic groups, particularly among Asian, Hispanic/Latino, and Pacific Islander populations. The new data collection requirements also will improve researchers’ ability to consistently monitor more dimensions of health disparities among people with disabilities. Collection of all data will take place under HHS’ longstanding, strict commitment to protecting privacy.
The standards, effective upon publication after accepting comments on proposed standards, apply to health surveys sponsored by HHS, where respondents either self-report information or a knowledgeable person responds for all members of a household. The standards will be used in all new surveys and at the time of major revisions to current surveys.
For more information on the final data standards, visit the Office of Minority Health website.
In November 2011, the National Library of Medicine (NLM) released a search box auto-complete feature for the NLM main website, MedlinePlus, and MedlinePlus en español. Auto-complete improves the search experience on these sites by:
- suggesting relevant terms and phrases as users begin typing;
- helping users execute searches and arrive at a focused set of results more quickly;
- guiding users to content that exists on the site;
- providing accurate spellings to help users avoid misspellings; and
- suggesting new lines of inquiry for users exploring a topic.
As a user types a query, a list of suggested terms and/or phrases displays dynamically beneath the search box. The suggested terms appear after three or more letters are entered into the box. The suggestions begin with or contain the word and/or phrase in the search query. Letters not yet typed appear in bold. As a user types more letters, the suggestions automatically update to reflect different terms or phrases. No more than five terms and/or phrases appear in the suggestion list for each query. A light gray bar highlights the suggestions as a cursor scrolls up or down the list. Users can also use the arrow keys on their keyboards to navigate through the list. Once a user clicks on the preferred term or phrase, the suggestion populates the search box, and the search engine executes the query. The auto-complete feature appears in search boxes across NLM main website, MedlinePlus, and MedlinePlus en español.
Please read the NLM Technical Bulletin to read more about this new feature.
Dealing with the symptoms of a serious illness is difficult. For the Hispanic population, language and cultural barriers can add to the burden, making it even harder to get relief. A new Spanish-language publication from the National Institute of Nursing Research (NINR), a component of the National Institutes of Health, provides those in the Hispanic community with information about palliative care, a comprehensive treatment that reduces or eliminates pain and other distressing symptoms of illness and medical treatments. NINR developed the brochure to increase awareness of palliative care among Hispanic patient and caregiving populations, and care providers who serve Hispanic communities.
Both the English and the Spanish version of NINR’s palliative care brochure highlight what palliative care is, who it benefits, and how it works. They also address:
- how to decide if someone needs palliative care
- how to ask a health care provider for palliative care
- how palliative care differs from hospice care
- what kind of specialists participate on a palliative care team
- insurance coverage for palliative care treatment
The palliative care brochures are available online for download and up to 25 complementary print copies can be requested. For more information about palliative care, please visit MedlinePlus or the NINR website.
