The problems we address are profound: - Medical error is the third leading cause of death in the US (Johns Hopkins) - Only 55% of patient case treatment algorithms follow recommended care standards (NEJM) - Once new clinical data proving superior patient outcomes for a medical product is released, it takes ~17 years for standards of care to change (World Bank) - Tens of billions of dollars are spent every year on SG&A by the healthcare industry getting new and innovative medical products in front of doctors (E&Y) - The US spends more than $10,000 per individual or 18% of GDP on healthcare, with estimates nearing $1 trillion dollars in total waste (JAMA) DocMatter provides physicians with actionable insights that every day lead to life-changing outcomes for patients around the world.
