Clinical and Economic Impact of an Electronic Medical Record Interfaced Decision Support System Reinforced With Patient Specific Pharmacogenetic Data for Minimizing Severe Drug-Drug Interactions

Clinical and Economic Impact of a Web Based, Electronic Medical Record Interfaced Electronic Decision Support System Incorporating Pharmacogenetic Evaluation for Physicians Intended, Mainly for Drug-drug Interaction. A Controlled Study in an Ambulatory Health Maintenance Organization Population

Leumit Health Services, an health maintenance organization operating in Israel, will incorporate a web-based, decision support system for handling drug-drug interactions and drug information, termed DDI+ reinforced with patient specific pharmacogenetic data. The investigators hypothesize that implementing such a system will reduce health-care expenditures (e.g., hospital admissions, referrals to ERs, Imaging procedures).
