One in Three Patients Fails to Fill Initial Prescriptions: Study

Nearly a third (31.3%) of all first-time drug prescriptions were not filled by patients within nine months, with nonadherence highest for expensive drugs and chronic disease prevention therapies, according to a study published in the Annals of Internal Medicine. Nonadherence factors were higher copayments, recent hospitalization and more severe comorbid conditions. The study, conducted by a primary care network, was aimed at estimating the incidence of primary nonadherence in primary care and identifying drug-, patient- and physician-related characteristics associated with nonadherence.
