Pathways to pharmacist prescriptive authority: Do decentralized models for expanded prescribing work?

Scope of practice decisions, such as granting pharmacists independent prescriptive authority, are governed at the state level and are often contentious debates. Five states - Florida (FL), New Mexico (NM), Colorado (CO), Idaho (ID), and Oregon (OR) -- have created structures that can theoretically expand independent prescriptive authority through decentralized approaches rather than needing the legislature to approve each drug that pharmacists may prescribe. These approaches have the potential advantage of allowing the states to expand independent pharmacist prescriptive authority to address public health needs more quickly. Four distinct models have been identified from most to least restrictive in practice: 1) medical veto; 2) interdisciplinary committee; 3) board of pharmacy; and 4) pharmacist-determined. These models have generally focused on postdiagnostic and preventive care by pharmacists. In terms of enabling broad pharmacist prescribing, only two of these models have demonstrated success: board of pharmacy and pharmacist-determined. Pharmacy and public health stakeholders considering similar legislation in their own states should consider the success of these decentralized models prior to enacting legislation.
