<p>Enhancing drug formulary accessibility can improve patient care and medication adherence. Formularies, which list covered medications, often include features like prior authorization and tiered pricing, leading to confusion and non-adherence. Improved transparency and integration of formularies into electronic health records could streamline prescribing processes, reduce administrative burdens, and enhance patient counseling. If formularies were more accessible, clinicians could better align treatment plans with coverage details, potentially reducing prior authorization delays and improving patient outcomes. Federal legislation can mandate formulary transparency, building on lessons from hospital price transparency initiatives. Such measures could foster a more patient-centric health care system by facilitating informed decision-making and optimizing formulary design. Enhanced accessibility would also support research and other efforts aimed at improving access to essential medications.</p>
