DESCRIPTION
for PharmacistsTRANSCRIPT
Secondary Literature:
• Definitions:– Resources which provide access to the
primary literature
• Examples:– Reviews & Systematic Reviews– Indexing & abstracting databases such as
PubMed (MeSH terms)
Secondary Literature:
• Advantages:– Provide efficient access to primary literature
• Limitations:– Users need to be adept at searching electronic
databases
• When to use:– When you need to find primary literature
• Reviews & Systematic Reviews
Secondary Literature:
• Systematic reviews can help practitioners keep abreast of the medical literature by summarizing large bodies of evidence and helping to explain differences among studies on the same question
Secondary Literature:
• These strategies include a comprehensive search of all potentially relevant articles and the use of explicit, reproducible criteria in the selection of articles for review
Secondary Literature:
• Primary research designs and study characteristics are appraised, data are synthesized, and results are interpreted
Secondary Literature:
• When the results of primary studies are summarized but not statistically combined, the review may be called a qualitative systematic review
Secondary Literature:
• A quantitative systematic review, or meta-analysis, is a systematic review that uses statistical methods to combine the results of two or more studies
Secondary Literature:
• The term "overview" is sometimes used to denote a systematic review, whether quantitative or qualitative
• Summaries of research that lack explicit
descriptions of systematic methods are often called narrative reviews
Secondary Literature:
• Used increasingly to inform medical decision making, plan future research agendas, and establish clinical policy, systematic reviews may strengthen the link between best research evidence and optimal health care
Secondary Literature:
• Indexing & abstracting systems
Secondary Literature:
• The two terms, indexing and abstracting, differ slightly
Secondary Literature:
• Indexing consists of providing bibliographic citation information (e.g., title, author, and citation of the article)
Secondary Literature:
• Abstracting also includes a brief description (or abstract) of the information provided by the article or resource cited
Secondary Literature:
• Basic search techniques !!!
Secondary Literature:
PubMed Versus Google Scholar

PubMed Versus Google Scholar
• Google Scholar searches retrieve results that include scholarly literature citations as well as other literature, including peer-reviewed publications, theses, books, abstracts, and other articles from academic publishers, professional organizations, and preprint repositories, universities, and other scholarly organizations
PubMed Versus Google Scholar
• Therefore, Google Scholar is able to retrieve more types of literature (i.e. books, theses, abstracts) compared with medical literature database retrieval search engines like PubMed
PubMed Versus Google Scholar
• More visitors were led to biomedical journal Web sites by Google Scholar within a year of release than by PubMed
• Google Scholar is less specific in locating published primary literature articles
PubMed Versus Google Scholar
• However, Google Scholar presents older literature (prior to 2000) first compared with PubMed
• However, PubMed searches revealed a greater number of target primary literature articles located compared with the target articles published after 2000
PubMed Versus Google Scholar
• In general, searchers perceive that Google Scholar searches yield more free, full-text journal articles compared with PubMed
PubMed Versus Google Scholar
• PubMed uses a sophisticated indexing system (i.e. MeSH terms) that categorizes search terms in a hierarchical manner to aid in systematically locating additional articles that may not be located with simple Google Scholar key word searches
• MeSH (Medical Subject Heading Terms)
PubMed Versus Google Scholar
• As the number of Internet-only journals that are not indexed in PubMed increases, Google Scholar searches may be able to locate more published literature that is unavailable in PubMed.

International Pharmaceutical Abstracts (IPA)
• This database is produced by the American Society of Health-System Pharmacists and includes information from over 750 pharmaceutical, medical, and health-related journals published worldwide since 1970
International Pharmaceutical Abstracts (IPA)
• The database covers the entire spectrum of drug therapy and pharmaceutical information so researchers such as toxicologists, those in cosmetic companies, medical librarians and health practitioners can easily locate the answers to any drug-related problems that they encounter
International Pharmaceutical Abstracts (IPA)
• Topics covered include information on bio-pharmaceutics & pharmacokinetics, new drug delivery systems, pharmacist liability, legal, political & ethical issues, and many others
• A unique feature of abstracts reporting clinical studies is the inclusion of the study design, number of patients, dosage, dosage forms, and dosage schedule
