What do Hot Springs, Rivers, and Soy Milk have in common? They are all liquids, and they are all new 2004 MeSH headings! As you are adjusting to the sound and feel of "2004," remember also that the New Year always brings changes to NLM systems and MeSH vocabulary. Recent NLM Technical Bulletin articles about this year's changes have been conveniently gathered at http://www.nlm.nih.gov/pubs/techbull/nd03/nd03_med_data_changes.html.
The 2004 version of MeSH is already in use for MEDLINE and is the default in the MeSH database, available from the PubMed sidebar. This year 666 new descriptors were added, 109 were replaced with more up-to-date terminology, 20 were deleted, and 484 see references were added! While some changes may seem trivial, others reorganize ("re-tree") large sections. Did you realize that the MeSH Trees were expanded from nine to eleven levels to accommodate increasing complexity and detail? This depth enabled MeSH developers to make major changes, notably to the B Category for Animals. The check tag Animal was changed to a new Animals descriptor/check tag, at the head of the rearranged Animals (B1) Tree. Vertebrates and Invertebrates lead major subdivisions under the new Animals term. The singular Animal term will map to the new plural, so searches can be inclusive or focused to specific animal groups. This change is more fully explained in the article at http://www.nlm.nih.gov/pubs/techbull/so03/so03_animals.html. The Bacteria (B3) tree has 310 new descriptors, in part to reflect changes in taxonomy as described in the second edition of Bergey's Manual of Systematic Bacteriology. Other new developments include: several changes in terminology for Ethnic Groups and Geographic Origins (Categories I and M); the toxicity subheading has a new definition, and Anti-Bacterial Agents is the new preferred heading for Antibiotics.
Some of my other "favorite" new MeSH headings: Complex Mixtures, F-Box Motifs, Holliday Junction Resolvases, Matrix Attachment Regions, Microbubbles, Quantum Dots, Refusal to Participate, and Trans Fatty Acids. A few of the new headings are strikingly close to non-scientific terms: Nitella (not Nutella), Volvox (not Volvo), and Sargassum (not Sarcasm). Don't forget Wigglesworthia. According to the scope note, without Wigglesworthia, Tsetse flies are infertile!
You may have also noticed changes in PubMed in recent weeks. If you truncate a term with an asterisk, PubMed will now process up to 600 variations (increased from 150). Since OLDMEDLINE citations are now part of PubMed, the system covers 50 years of bibliographic data! The ability to email results directly from PubMed was introduced last summer. About the same time, icons indicating free full-text appeared on the summary display. To keep up with changes, read the NLM Technical Bulletin and check PubMed's New and Noteworthy links. Trust and Friends were new headings last year, no kidding.

More elders are using the Internet all the time. Looking for health information is one of the most common activities on the Internet. This project was a result of these two trends. The purpose was to develop an easy-to-use web site with quality health information for elders, including links to local and national resources.
Visit The Prepared Caregiver at http://www.ohsu.edu/healthyaging/caregiving
Key project participants were Mary Devlin, MAT, MLS (OHSU, Medical Informatics), Project Manager; Andrea Drury, MLS (RareHeron Web Design), Information Architect; Kayo Parsons-Korn (RareHeron Web Design), Designer; and Dolores Judkins, MLS (OHSU Library), Project Coordinator.
Based on interviews with Oregon Health & Science University (OHSU) School of Nursing faculty and on suggestions from Marna Flaherty-Robb, the project's original liaison person with the School and the Center for Healthy Aging, the content of the site was narrowed to caregiving for elders. It was critical to put boundaries on the project, and with caregiving still a large subject area the focus was further defined as information useful to potential and new caregivers for elders. We assumed that the primary users of the site would be spouses or adult children of elders needing care.
Further content definition came from our decision to have the site concentrate on information for action rather than general knowledge. We included information about where to get help and specific guidelines. We also decided to incorporate psycho-social as well as bio-physical information.
We knew that the language used on the site had to be suitable for the audience and must avoid health care jargon. The reading level had to be no higher than eighth grade. At the same time, we wanted to avoid any sense of talking down to people.
Basic technical assumptions defined for the site included:
Site development depended in part on usability information elicited from elders during focus group sessions. Information from the focus groups was also used to meet the secondary goal of the project which was to research the overlap between generally accepted best practice for elders' usability and usability requirements evoked from elders themselves.

Dragonfly, Fall 2003 -- Volume 34 Issue 4

It all started ten years ago, in November 1993, when a regional health sciences library discussion list, HLIB-NW, made its debut with 80 subscribers. The purpose of HLIB-NW remains "to facilitate electronic communications via the Internet among the health sciences library community in the Northwest. It provides a forum for discussing practical, theoretical, and philosophical issues and for exchanging advice, information, ideas, and resources of interest to its intended audience."
HLIB-NW was created and continues to be maintained by Maryanne
Blake and Michael Boer of the NN/LM PNR;
however, it is not the official voice of the Regional Medical
Library (RML). It is an unmoderated discussion list and the
topics are those initiated by the subscribers. The subjects of
messages include
• publicizing regional meetings, classes, and other educational
offerings;
• making announcements of regional interest, such as retirements
and job postings;
• sharing information and resources, especially interlibrary
loans and giveaway journals and books; and
• asking for and giving advice to colleagues.
Often thanks are posted in response to help asked of colleagues. For instance, "Thank you to all for your help, not just with this request, but with all requests. You are all valuable to the success of our profession!" and "What a great group of colleagues! PAC NW Region rocks!!!!!"
Some interesting factoids about HLIB-NW:
If you are not on HLIB-NW and would like to join in the discussion go to the HLIB-NW List FAQ <http://nnlm.gov/pnr/hlib-nw.html> for more information, including how to subscribe.

Alaska Health Education Library Project Outreach
The lead agency for this project is the Health Promotion Unit at the Division of Public Health in Juneau, Alaska. The purpose of the Alaska Health Education Library Project (AHELP) is to ensure that health professionals, their patients and the general public in Alaska are connected to the health information resources they need to make informed health care decisions, specifically by linking to the resources of the Alaska Health Education Library Project and its partner libraries. The Alaska Health Education Library Project (AHELP) is an electronic clearinghouse of current health promotion and health education resources that are specific to and available in Alaska. It contains information on health promotion programs, projects and materials and more. AHELP is designed to serve professionals in the field of health promotion and health education, as well as other public health professionals. It is intended to assist the professional in their everyday job and promote sharing, networking and collaboration. Visit the AHELP web site at: http://www.ahelp.org.
In order to meet the goal of the ensuring that health professionals, their patients, and the general public in Alaska are connected to health information resources, project participants will:

Dragonfly, Fall 2003 -- Volume 34 Issue 4
We are happy to announce the libraries that will receive funding from the Pacific Northwest Regional Medical Library to begin or expand electronic document delivery services. Six libraries in the Pacific Northwest Region of the National Network of Libraries of Medicine submitted proposals for Electronic Document Delivery for DOCLINE Libraries awards in response to the August announcement of funding (http://nnlm.gov/pnr/news/200307/edd.html). We had advertised the availability of five awards for up to $2,000-but because several of the proposals were for significantly less than the maximum, we were able to fund all six proposals. These projects represent a range of approaches to implementing electronic document delivery (EDD), revealing the differences between institutional environments and needs.
Kaiser Permanente Center
for Health Research Library, Portland, OR
Award amount: $699.
After concerted effort, Daphne Plaut recently resolved networking, security, and firewall issues and her library can now use Ariel on a workstation with a T1 line through a secure firewall. The library receives Ariel documents, converts them to pdfs, and emails them to customers. The library had purchased the full version of the Ariel software (receiving and sending both) and will use this award from NN/LM PNR to acquire a scanner. This will allow electronic delivery of interlibrary loan requests to DOCLINE and OCLC libraries, using Ariel to send scanned documents; and electronic delivery of print collection copies to Kaiser Permanente Center for Health Research staff, using either Ariel or the software that is provided with the scanner.
National
College of Naturopathic Medicine Library, Portland,
OR
Award amount: $1,555.
Rick Severson's library established a full interlibrary loan program about three years ago, at the urging of various accrediting agencies. The program is growing at a steady rate and they are a net lender by virtue of a unique collection. A grant from Aboca, an Italian herbal corporation, enabled the library to purchase a PC and a scanner; this award from NN/LM PNR will be used to buy Ariel software in order to send and receive electronic documents instead of relying so heavily upon mail, fax, and shipping. This award will also be used to acquire Adobe Acrobat to create and manipulate pdf files, and Clio software for tracking and organizing ILL transactions.
Providence Everett Medical Center Library, Everett,
WA
Award amount: $1,408.
Sue Innes uses Outlook Express for electronic delivery to patrons of articles from journals for which her library has online access. This service has brought timeliness, clarity of copy, and decreasing costs. Funds from this NN/LM PNR award will allow the library to expand its email document delivery service to include copies of articles from its print collection. Following the recommendation of the medical center's information systems department, the library will acquire a scanner and OmniPage Pro Office software for document conversion and pdf formatting. Award funds will also be used cover labor costs of software and scanner installation.
St.
Joseph Medical Center Library, Tacoma, WA
Award amount: $1,062.
Brynn Beals will use this award to upgrade her library's current Ricoh copy machine to one with scanning capability, to provide a data line for this machine, and to purchase Adobe Acrobat. This will give her library the ability to scan and send pdf documents via email. Ricoh is the vendor for all Franciscan Health System photocopiers, fax machines, scanners, etc. The institution has made the decision to move toward multifunction devices so this upgrade will support that initiative and enhance library services.
Tuality Healthcare
Health Sciences Library, Hillsboro, OR
Award amount: $926.
For the libraries at Tuality Healthcare, Judith Hayes will use this award to acquire a scanner and Ariel software. These will make it possible to use the hospital library staff computer for scanning articles into tiff or pdf, and transmitting via web email as attachments. Their institutional MIS is currently designing an in-house tool for secure passwords to documents stored on the hospital intranet, a web pick-up system that they hope to use for articles to in-house patrons. If this is successful, they hope to provide access to scanned articles via Web pick-up from their Web server to fill ILL requests from other institutions.
Willamette Falls
Hospital, Oregon City, OR
Award amount: $2,000.
In collaboration with her hospital's IT department, Kathy Martin will use the award from NN/LM PNR to acquire a scanner, Adobe Acrobat, and Ariel plus Norton Personal Firewall to protect the library's dedicated EDD computer. The award will also be used to fund technical support assistance from Symantec to set up the firewall and open up two ports for the EDD machine. This project will expand the library's options for document delivery to patrons and to other libraries, enabling faster, more efficient service through computer-to-computer transmission and receipt of articles.
Congratulations to these six libraries!

Cross Cultural Health Care Program
The Cross Cultural Health Care Program (CCHCP) is a non-profit organization that endeavors to connect health care and communities. CCHCP's activities and projects include medical interpreter and cultural competence training, publishing bilingual medical glossaries and other publications, community-based research and demonstration projects, and its library or Resource Center, which is open to the public. The Resource Center has a specialized collection on culture and health issues and provides reference assistance and borrowing privileges to health care providers, students, and others.
The Cross Cultural Health Care Program's Resource Center received a National Network of Libraries of Medicine (NN/LM) grant for the period from November 2001 through May 2003. The end of 2001 and beginning of 2002 was a difficult transitional period for CCHCP, as the organization separated from PacMed Clinics in Seattle and became its own independent 501(c)(3) non-profit. NN/LM PNR allowed us to start the project in June of 2002, when we were ready.
We wanted to help people in the Puget Sound area, especially providers, connect to information relevant to cultural issues in health but weren't sure what approaches to take. First, a needs assessment survey was sent to about 240 area organizations, with an emphasis on safety-net providers, professional associations, and advocacy organizations. The response rate was 20%. Many respondents expressed an interest in learning to access such information, and several suggested "email updates" or a newsletter as a preferred way of receiving information.
Four customized trainings/presentations were given at clinics or within longer CCHCP trainings, which included extensive packets of materials catering to each audience's needs and interests. Keeping in mind the wide variety of participants' skill levels, content was designed not only to provide resources on the spot, but also to provide some basic tools and specific ideas to take away and make people aware of the free or inexpensive resources available through public libraries and the National Library of Medicine (NLM). Every group of participants, which ranged in size from seven to forty, was very ethnically diverse with a substantial number of people of color. A field trip by a group of University of Washington School of Public Health graduate students comprised a similar but less formal event.
Promotional activities included development of a library brochure, now in its second printing, and a display at CCHCP's open house to celebrate our new office in January 2003. The Resource Center was previously housed in a basement in one of PacMed's buildings; it is now housed in the comfortable and attractive front office of our new suites, with large south-facing windows. We now provide PubMed and MEDLINEPlus Basics brochures to visitors thanks to the grant.
Lastly, we distributed five issues of a newsletter called Cross Cultural Resources. Modified from the old "new acquisitions list," the newsletter provides mostly annotated collections of online, print, and other resources on a particular culture and health-related subject, often with tips for using the Internet or NLM resources. Focus subjects have included "Diabetes nutrition in diverse communities," "Community profiles on the web," "Cultural competence," and more, with the intent of not duplicating others' work. So far the newsletter has around 220 subscribers, many of whom pass it on to untold numbers of colleagues. Most subscribers are directly involved with providing health care in underserved, limited English-speaking, or culturally diverse communities and are often part of these communities themselves.
On the whole, the project was a challenging learning experience. The trainings/presentations aspect was expected to be a large part of it. We didn't plan beforehand exactly who to work with, which apparently wasn't the right way to go. However we let the needs assessment guide us and that was a good barometer of what people like, where their skills levels are, and what they are looking for. There were a few other activities we wanted to do but there wasn't time or internal resources. Instead, the newsletter took on a life of its own and became quite popular, drawing wonderful feedback.
Thanks to NN/LM PNR, especially Linda Milgrom, and everyone
involved, for the opportunity and patience.

Here's an interesting string of facts that you might find useful in publicity for National Medical Librarians Month (October) or any other time of the year:
10 Reasons Why Medical Information is Critical and Medical Librarians are Life Savers!*
*Compiled by research staff at Ovid Technologies, Inc. and used with permission.
1) Serious or potentially serious medication errors occur in
6.5% of hospitalized patients; medical errors occur in
2.9-3.7%
Brennan et al. "Incidence of adverse events and negligence in
hospitalized patients: Results of the Harvard Medical Practice
Study I." N Engl J Med. 324:370-376, 1991.
2) Between 6.6% and 13.6% of medical errors lead to death,
which equates to between 44,000 and 98,000 patient deaths every
year.

4) A 700-bed hospital spends more the $2.8 million each year
fixing preventable ADE.
Bates, David W et al. "The cost of adverse drug events in
hospitalized patients." JAMA 277:307-311, 1997.
5) Frequency of questions occurring in clinical practice
(0.7-1.5 per patient).
Smith, R. "What clinical information do doctors need?"
BMJ 1996;313:1062-1068.
6) Questions about therapy predominate (50%+), while
diagnostic issues account for less than 30% of questions.
Ebell M. "Information at the point of care: Answering clinical
questions." J Am Board Fam Pract 1999; 12(3):
225-235.
7) Over 70% of questions remain unanswered due to lack of
time, forgetting the question and a perception that an answer
would/could not be found.
Green ML, Ciampi MA, Ellis PJ. "Residents' medical information
needs in clinic: Are they being met?" Am J Med 2000;
109(3); 218-223.
8) Green et al. demonstrated that a group of residents
believed that:
• 70% of evidence-based answers to their questions would have
changed the management of patients.
• 34% of questions might involve harm for the patient if not
answered.
• ?24% of questions were urgent.

decision making: The Rochester Study." Bull Med Lib
Assoc, 1992; 80(2): 169-178.
10) These changes reduced mortality risk in 19% of patients,
avoided hospitalization in 12% of cases, changed diagnostic tests
in 51% and drug choice in 45%. Overall length of stay in hospital
was reduced in 19% of patients.

A new version of DOCLINE will be released before the end of the year: DOCLINE Version 2.0. With this new version, DOCLINE has a sleeker look and feel combined with a completely redesigned DOCUSER module that has a new name: Institutions. The new Institutions module is easier to update, has more flexible ways to work with your Routing Table, improved search functionality, new ways to express charges, and much more. You can view a sneak preview of DOCLINE Version 2.0 at http://nnlm.gov/libinfo/docline/doclinev2.ppt.
DOCLINE Version 2.0 is in testing now. NLM will soon invite all DOCLINE libraries to participate in testing the new system. Details will be provided via DOCLINE-L, HLIB-NW, and your DOCLINE Home Page.
*For those of you old enough to remember the 1978 publicity
campaign for the movie "Jaws II"
With the goal of relieving libraries from having to key their holdings information into multiple systems, NLM has been working to establish several batch update programs to output data from SERHOLD to external systems or accept data from other systems. NLM recently announced its plans for a transfer of journal holdings information from OCLC WorldCat to SERHOLD! Deena Acton of NLM Serial Records provided details in a message to the DOCLINE-L email discussion list:
"NLM continues to work with OCLC to provide data exchange of holdings records between DOCLINE and OCLC. As you know, NLM exported holdings records in July which OCLC loaded successfully on August 16 for libraries authorizing us to do so. However, libraries that share OCLC Codes are not able to use SERHOLD to OCLC batch update. As an alternative, these libraries may want to use the upcoming OCLC to SERHOLD Batch Update.
[Editor's note: this upcoming OCLC to SERHOLD Batch Update is in the opposite direction from the recently released SERHOLD to OCLC Batch Update.]
On August 26, NLM successfully loaded 6,693 holdings records for our pilot library, the University of North Carolina at Chapel Hill. Additional work is needed to provide the functionality within DOCLINE. We plan to release OCLC to SERHOLD Batch Update capabilities early next year. Stay tuned to DOCLINE-L for further announcements.
Additional information can be found in the following FAQs and sections of Help:
- When will OCLC to SERHOLD Batch Update be available?
(http://www.nlm.nih.gov/services/doc_batch_update_oclctoserhold_availability.html)- My library is part of a larger institution that use one OCLC code (ex. MWF) with multiple holding library codes for each "branch" (ex. MWFA and MWFB). Can my library still participate in SERHOLD to OCLC Batch Update?
(http://www.nlm.nih.gov/services/doc_batch_update_serholdtooclc_multiple_oclcids.html)- What is planned for Batch Update capabilities?
(http://www.nlm.nih.gov/services/doc_batch_update.html)Thanks to UNC Chapel Hill for participating in the testing during the entire span of this project!"
In related news this past spring, we announced OCLC's ability to accept from NLM batch transfers of SERHOLD data so that DOCLINE libraries' journal holdings can be displayed in WorldCat (see "SERHOLD to OCLC Batch Update Is Here!" in Dragonfly, Spring 2003, 34(2) at http://nnlm.gov/pnr/news/200304/batch.html). A few months later we celebrated the success of the first SERHOLD-to-OCLC journal holdings transfer (see "First SERHOLD-to-OCLC Batch Update Is a Success!" in Dragonfly, Summer 2003, 34(3) at http://nnlm.gov/pnr/news/200307/oclc.html). The upcoming ability to send batch data transfers in the other direction, from OCLC to SERHOLD, will be an important step towards libraries' being able to eliminate re-keying of journal holdings information.
