University of South Alabama: Biomedical Library Sites Baugh Biomedical Library – Campus Site Primarily supports the academic health sciences (College of Medicine, Colleges of Nursing & Allied Health)
University of South Alabama: Biomedical Library Sites Third floor of the University Medical Center site and now called the Health Information Resource Center Primarily supports the clinical medicine specialties-collection concentrates on patient care and treatment
University of South Alabama: Biomedical Library Sites Children’s and Women’s Hospital site Primarily supports obstetrics, gynecology, and pediatrics – which is reflected by the library’s collection.
Objectives Students can describe challenges inherent in using biomedical literature. Students are aware of the USA Biomedical Library’s resources and services.
Objectives Students can acquire, evaluate, utilize, and manage the information contained in the biomedical literature held at the USA Biomedical Library.
Biomedical Literature: the Challenges VOLUME VARIETY VARIOUS POINTS OF ACCESS RELIABILITY
VOLUME Set of journals pertinent to primary care physicians in 2002 found 7,287 articles are published monthly in this set of journals. A physician trained in epidemiology would take an estimated 627.5 hours per month to evaluate articles pertinent to his practice. 1
VOLUME Nurses, who need to provide decision makers with relatively concise ‘‘bottom- line’’ estimates of effectiveness, report approximately 1,000 systematic review and meta-analyses studies that focus on topics important to infection control professionals are published annually. 2
VOLUME In biomedical research, the amount of experimental data and published scientiﬁc information is “overwhelming and ever increasing, which may inhibit rather than stimulate scientiﬁc progress.” 3
VARIETY Primary information Secondary information
The Medical Literature Primary – original research Experimental (an intervention is made or variables are manipulated) Randomized Control Trials Controlled trials Observational (no intervention or variables are manipulated) Cohort studies Case-control studies Case reports
Secondary – reviews of original research Meta-analysis Systematic reviews Practice guidelines Reviews Decision analysis Consensus reports Editorial, commentary The Medical Literature
VARIOUS POINTS OF ACCESS Personal Libraries: books & journals Colleagues Personal experience Libraries Electronic Information sources (databases) Internet BARRIERS
RELIABILITY Information on the Internet about head injury pertaining to intensive care: less quantity and more quality is needed.(2006) PMID: 16749874 Rating health information on the Internet: navigating to knowledge or to Babel? (1998) PMID: 9486757
RELIABILITY Accessibility, nature and quality of health information on the Internet: a survey on osteoarthritis. (2005) PMID: 15572390
What is Evidence Based Practice (EBP) Short definition: “the integration of best research evidence with clinical expertise and patient values.” 4
Overwhelmed? So many options – so much information... and misinformation. The library provides numerous tools to help you navigate this flood of information. BOOKS? JOURNALS? INTERNET?
Biomedical literature is “overwhelming and ever increasing, which may inhibit rather than stimulate scientiﬁc progress.” Information Management Focuses on using valid information that which is relevant that which is accessible

PubMed PubMed is a service of the U.S. National Library of Medicine that includes over 19 million citations from 4,800 biomedical journals for biomedical articles back to 1948.U.S. National Library of Medicine PubMed includes links to full text articles and other related resources.
Advantages of PubMed Free Links to publisher’s sites for full-text journals Or, can order full-text journal articles Clinical Queries/Systematic Reviews section limits retrieval to evidence-based citations
More Advantages of PubMed Can easily limit your search to: – Age groups – Human or Animal studies – Language – Review articles – Subsets, such as Core Clinical Journals or CAM Clipboard allows you to save citations from one search or several searches that you may want to print, save, email, or order My NCBI allows you to save search strategies in order to generate updates - including automatic e-mail updates
