ABSTRACT
Objectives: Prior authorization (PA) aims to promote the safe and effective use of medications and to control costs. However, PA-related administrative tasks can contribute to burden on health care providers. This study examines how such tasks affect treatment decisions.
Study Design: Cross-sectional, online survey.
Methods: We conducted an online survey of US medical providers in 2020 based on a convenience sample of 100,000 providers. Multivariate path analysis was used to examine associations among provider practice characteristics, step therapy and other health plan requirements, perceived burdens of PA, communication issues with insurers, and prescribing behaviors (prescribing a different medication than planned, avoiding prescribing of newer medications even if evidence-based guideline recommendations are met, and modifying a diagnosis). Weighted analyses were conducted to assess nonresponse bias.
