Research funded by the National Library of Medicine provides new insight into why patients stop taking drugs that lower their cholesterol, and what happens when patients try those drugs, known as statins, a second time. Researchers found that more than 90% of patients who stopped taking statins because of an adverse reaction could tolerate the medication when tried again. The study is published in the April 2, 2013, issue of the Annals of Internal Medicine.
NLM grantee Alexander Turchin MD, MS, of Brigham and Women’s Hospital, a teaching affiliate of Harvard Medical School, notes that statins are commonly stopped even though their benefits are well documented. He and colleagues wanted to better understand why statins are discontinued and whether adverse reactions play a role. They conducted a retrospective study, analyzing clinical data in an electronic medical record (EMR) system. Researchers examined structured data as well as the narrative electronic notes of health providers. Those notes frequently are the only place in an EMR where adverse reactions to medications are documented. Using the NLM grant, researchers developed natural language processing software and scoured more than 5 million notes, on more than 107,000 patients, recorded over nearly a decade. The software generated data on a scale that could not have been done manually. Researchers say the next step would be to conduct a clinical trial to determine if outcomes are improved when statins are tried again, after an adverse event.

Selection decisions will be made by mid-February. The costs for attending this course, including travel, housing, and meals, are fully supported by the National Library of Medicine. Sessions are limited to 30 participants. This is a National Library of Medicine fellowship program directed at medical educators, medical librarians, medical administrators, and young faculty, who are not currently knowledgeable but can become agents of change in their institutions.
This week-long survey course is designed to familiarize individuals with the application of computer technologies and information science in biomedicine and health science. Through a combination of lectures and hands-on computer exercises, participants will be introduced to the conceptual and technical components of biomedical informatics. The conceptual components will include principles of database design, human-computer interfaces, medical terminologies and coding systems, medical decision analysis methods, clinical information systems architectures, and methods for measuring costs and benefits in health care systems. The technical components will include use of the Internet for biomedical applications, current and emerging wide area network technologies, use of literature and molecular sequence databases, and systems for telemedicine. Evening workshops will include hands-on project development to give students the opportunity to bring their own expertise to bear, and apply the lessons learned in class to a relevant informatics application.
The course dates for 2013 are:
- Spring Session: May 26 – June 1, 2013
- Fall Session: September 15 – 21, 2013

A new funding announcement offering support for informationists to work on NIH-funded research grants was published on the NIH Guide web site today. These supplements provide funds to researchers who have existing research grants from any of the Institutes listed in the announcement (NLM, NCI, NEI, NIA, NIAAA, NIBIB, NIDCD, NIDCR), to pay for adding an informationist to the project. The principal investigator of the grant must apply for this funding, so librarian/informationist colleagues in academic settings might want to identify partners of interest and reach out to them to suggest that they apply, or alert people with whom they already work. An easy way to find potential partners would be to use the NIH RePORTER resource to search by state and funding agency. Applications must be submitted electronically by the deadline of June 5, 2012. The earliest funding start date is September, 2012.
The purposes of the administrative supplement program are (1) to enhance collaborative, multi-disciplinary basic and clinical research by integrating an information specialist, also known as in-context information specialist, into the research team in order to improve the capture, storage, organization, management, integration, presentation, and dissemination of biomedical research data; and (2) to assess and document the value and impact of the informationist’s participation.
