The HHS Office of Inspector General (OIG) has issued two reports on electronic prescribing (e-prescribing) in the Medicare Part D program. First, a report entitled "Medicare Part D E-Prescribing Standards: Early Assessment Shows Partial Connectivity" discusses the extent to which Part D plan sponsors have implemented Part D e-prescribing standards promulgated by CMS. Based on a survey of all plan sponsors between August and September 2008, nearly 80% of plan sponsors reported at least partial plan-to-prescriber connectivity, but few reported complete connectivity. Most plan sponsors had complete plan-to-dispenser connectivity. A second report, "Medicare Part D Plan Sponsor Electronic Prescribing Initiatives,” found that plan sponsors have launched voluntary e-prescribing initiatives to increase prescriber adoption of e-prescribing. As of September 2008, more than a third of sponsors had implemented or planned such initiatives, which included such components as free or discounted software, hardware, training, internet connectivity, or financial incentives. Some sponsors who implemented such initiatives reported an increase in generic substitutions and formulary compliance.
