Welcome to JAMAevidence

Evidence-based medicine (EBM) integrates the best available evidence with clinical experience that allows clinicians to recommend, and their patients to make, informed choices consistent with their values. JAMAevidence helps decision makers identify the best available evidence by providing guides to the systematic consideration of the validity, importance, and applicability of claims about the assessment of health problems and the outcomes of health care.

Two types of worksheets are available on JAMAevidence: critical appraisal guides and information cycle problem-solving aids. They may be printed, edited, and saved to a user's personal profile. Users fill in a rich-text editing box with a formatting toolbar and spellcheck.

Critical Appraisal

Critical appraisal forms help users learn to evaluate research findings by considering validity, importance, and applicability of results. Notes entered into these worksheets by individually identified users are stored for later access and revision. Critical appraisal forms are available via their specific locations in the Users' Guides text, as well as on a user's My Access account page.

Information Cycle
