The eHealth First is an IT-platform to support decision-making in the field of health management, longevity, diagnostics, the prevention and treatment of common diseases for non-specialist users, medical specialists, researchers and business, based on blockchain technology, machine learning, natural language analysis, neural networks, big data, clinical epidemiology, evidence-based medicine and telemedicine. EHF is a platform that is built to expand. At the core of the entire platform is a database - a knowledgebase - of medical literature. The platform currently includes two apps that function by using AI and natural language processing to quickly reference necessary medical information from this literature. The first app is a consumer grade home diagnosis and medical recommendation app. The user completes an initial medical screening, and receives a thorough preliminary analysis of their health, along with recommendations for treatment or consultation with a live physician.
