HSCI 4311: Community Health Education: Evidence Based Health Care
Created by the United States Cochrane Center, this tutorial is divided into sections and is structured like a lecture.
Strongest Types of Evidence Based Information
Systematic Reviews: Usually focus on clinicat topic and answer a specific question. Searches systematically the literature available to find valid studies with good methodology. It is not original research it reviews the research that has already been conducted. Some might list the keywords and databases used for finding such research.
Meta Analysis: A systematic review which combines vast reseach and then analyzes the data with statistics
Randomized Controlled Trials: A research study in which participants are randomly placed in a control and comparison group. Blinding of participants and researchers is an important aspect to reduce bias.

Evidence- based healthcare comes into practice when a clinician or care provider conscientiously takes into account (1) their own clinical and professional experience, (2) the best available external clinical research, and (3) the unique qualities of the patient or case in question.
In practice, one will have their professional experience and the particular qualities of the case immediately available to them; external clinical research, however, is something one must learn to locate and distinguish among.
Types of Evidence
The Systematic Review-- the "Gold Standard" of Evidence
Bibliographic index for the professional literature of nursing, allied health, biomedicine, and healthcare derived from English-language and selected international source materials. Subject coverage includes management, behaviorial sciences, health sciences, librarianship, education, and consumer health. Materials indexed include journals, books, book chapters, pamphlets, audiovisuals, dissertations, educational software, conference proceedings, standards of professional practice, nurse practice acts, critical paths, and research instruments.
A collection of evidence-based medicine databases, including the Cochrane Database of Systematic Reviews (Cochrane Reviews), the Database of Abstracts of Reviews of Effects (DARE), the Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Database of Methodology Reviews (Methodology Reviews), the Health Technology Assessment Database (HTA), and the NHS Economic Evaluation Database (NHS EED). Includes full text, systematic reviews of empirical studies, complete with graphs, figures, odds-ratio diagrams, and tables, many of which can be manipulated for statistical analysis.
PubMed is a free service provided by the National Center for Biotechnology Information (NCBI) of the U.S. National Library of Medicine (NLM). It provides indexing for bibliographic citations from MEDLINE (1966 - present), OLDMEDLINE (1950 - 1965), out-of-scope and publisher-supplied citations, in-process records, and selected other NLM-reviewed life science journal articles with full text in PubMedCentral. Provides comprehensive coverage of international biomedical literature. Materials indexed include scholarly journals, newspapers, magazines, and newsletters. Many citations include abstracts and some include free full text or links to full text, based on institutional subscriptions.
Comprehensive index for international literature in biomedicine, bioengineering, and health. Includes those areas of the life, behavioral, and chemical sciences needed by health professionals and others engaged in basic research and clinical care, public health, health policy development, or related educational activities. Subject coverage includes medicine, nursing, dentistry, veterinary medicine, the health care system, and the pre-clinical sciences. Materials indexed include scholarly journals, newspapers, magazines, and newsletters. This database is made possible by TexShare.
