“JAMA’s User’s Guides to the Medical Literature: essentials of evidence-based clinical practice” by Guyatt, Gordon [Available at UAMS Library]
The complete set of Users’ Guides originally published as a series in the Journal of the American Medical Association (JAMA).
MDCalc (Medical calculator)* – MDCalc includes clinical tools and databases intended for use by healthcare professionals. The contents of the MDCalc Site, such as text, graphics and images are for informational purposes only. MDCalc does not recommend or endorse any specific tests, physicians, products, procedures, or opinions.
- EBM Calculators – Online calculators from the Centre for Evidence-Based Medicine, Oxford University. Includes: All-purpose 2×2, Diagnostic, and Interactive Nonogram, calculators.
- Formula – Likelihood Ratio
- Formula – Risk and Number Needed to Treat Worksheet
- Template – Critical Appraisal – Case Control – Harm/Observational Study
- Template – Critical Appraisal – Clinical Practice Guidelines
- Template – Critical Appraisal – Diagnostic Test
- Template – Critical Appraisal – Prognosis
- Template – Critical Appraisal – Prospective Cohort/ Observational Study
- Template – Critical Appraisal – Systematic Review
- Template – Critical Appraisal – Therapy
- AHRQ Evidence Based Reports – The Agency for Healthcare Research and Quality (AHRQ) is the health services research arm of the U.S. Department of Health and Human Services (HHS). Evidence Based Practice Center reports are arranged by topic.
- The National Guideline Clearinghouse (NGC) – Contains structured, standardized summaries containing information derived from guidelines using the NGC Template of Guideline Attributes. Search or browse by standard terminology (controlled vocabulary) to search for summaries by clinical specialty, implementation tools, various methods used, and other attributes. Guideline syntheses are also included and are systematic comparisons of selected guideline that address similar topic areas.
- The National Quality Measures Clearinghouse (NQMC) – Provides information on specific evidence-based health care quality measures and measure sets.
- HHS Measure Inventory – Hosted by the NQMC, the HHS Measure Inventory is an inventory of the measures that are currently being used by the agencies in HHS for quality measurement, improvement, and reporting. “Cross links” are included for those measures that are in both the HHS Measure Inventory and represented in NQMC.
Critically Appraised Topics
BestBETs (Best Evidence Topics)* – BETs were developed in the Emergency Department of Manchester Royal Infirmary, UK, to provide rapid evidence-based answers to real-life clinical questions, using a systematic approach to reviewing the literature.
BMJ Clinical Evidence – The UAMS Library does not subscribe but individuals may purchase 48-hour and 30-day access passes. Clinical Evidence is a decision-support resource for evidence-based medicine. Rather than starting with the evidence and just summarizing it, the BMJ Clinical Evidence editorial team first identifies the key clinical questions. Then they search for and summarize the best available evidence to answer them. Sign up for a “My BMJ Clinical Evidence” account to receive updates on topics of interest to you.
- CATs Library – CATs from the University of Texas Health Science Center at San Antonio Dental School.
- Critically Appraised Topics (CATS) – CATs from the University of British Columbia. CATs are standardized summaries of evidence based on a clinical question or PICO. Synthesis includes critique of validity and relevance of the evidence to EBM.
- CATMaker – CATmaker is a computer-assisted critical appraisal tool, which helps you create Critically Appraised Topics (CATs), for the key articles you encounter about Therapy, Diagnosis, Prognosis, Aetiology/Harm and Systematic Reviews of Therapy. PC download only. Created by the Centre for Evidence-Based Medicine, University of Oxford.
theNNT (Number Needed to Treat)* – theNNT offers a measurement of the impact of a medicine or therapy by estimating the number of patients that need to be treated in order to have an impact on one person. It is maintained by a group of physicians using a framework and rating system to evaluate therapies based on their patient-important benefits and harms as well as a system to evaluate diagnostics by patient sign, symptom, lab test or study. theNNT accepts no outside funding or advertisements.
