VisualDx is a trusted knowledge base to support improved medical-decision making.


Evidence-Based Approach

VisualDx knowledge and recommendations are based on best available evidence ordered according to standard industry protocols, interpreted by expert opinion. Best available evidence is evaluated by source type, validity, and clinical suitability. Leading content sources (eg, Ann Intern Med, BMJ, CDC STD Treatment Guidelines, Cochrane Database Syst Rev, IDSA Practice Guidelines, JAMA journals, Lancet, Med Lett Drugs Ther, Medicine [Baltimore], MMWR Morb Mortal Wkly Rep, MMWR Recomm Rep, N Engl J Med, Pediatrics) are reviewed, as is medical literature in general, with ongoing targeted searches in MEDLINE and PubMed. Editorial contributors and staff follow a protocol from most to least evidence: from meta-analyses and systematic reviews of randomized controlled clinical trials to cohort studies to case-control studies to case series to individual expert opinions.
