(SDI) Vector One National (VONA) SDI Vector One Measures dispensing of prescriptions Information on physician specialty, patient s age and gender, and estimates for numbers of patients continuing or beginning new therapy. Integrates prescription activity from a variety of sources Retail chains, mass merchandisers, mail order pharmacies, pharmacy benefit Retail chains, mass merchandisers, mail order pharmacies, pharmacy benefit managers, provider groups. Receives over 2 billion prescription claims a year, representing over 160 million unique patients.
