Background: Prior authorization (PA) of medications is widely used by payers in the United States as a way to promote safe and effective use of medications and to control costs. However, PA-related tasks such as completing forms, submitting forms, researching medical history and submitting required documentation can all contribute to burden on healthcare providers. This study examines how such tasks and affect provider burden and treatment decisions.
Methods: We developed and administered a nationwide, cross-sectional online survey of medical providers in the United States in 2020 based on a convenience sample of 100,000 providers (physicians, nurse practitioners, and physician assistants). Path analysis was used to test the associations between provider practice characteristics, step therapy and other health plan requirements, perceived burdens of PA, and communication issues with insurers on prescribing behaviors, which included prescribing a different medication, avoiding prescribing of newer medications, and modifying a diagnosis. Weighted analyses were also conducted to account for sample bias due to non-response.
Results: A total of 1173 providers (1.2% response rate) provided 1147 usable surveys. The sample was 49.6% female, and a majority were MD/DO providers (85%). Step therapy requirements had the largest influence on prescribing a different medication than planned (b = .22, 95% CI = .160-.285) and avoiding prescribing a newer medication despite meeting evidence-based guidelines (b = .24, 95% CI = .181-.309). A unit-weighted index of perceived PA burden risk was associated with prescribing a different medication (b = .09, 95% CI = .012-.128) and modifying a diagnosis to obtain PA approval (b = .14, 95% CI = .065-.195). Communication issues were associated with prescribing a different medication (b = .11, 95% CI = .029-.186), while health plan requirements (e.g., clinical documentation) was significantly associated with all three prescribing outcomes. Weighted analyses showed that the study conclusions were unlikely to have been biased by nonresponse.
Conclusions: Providers report altering prescribing and modifying diagnoses to avoid PA requirements and related burdens. Processes that reduce the administrative burden of PA through improved communication and transparency as well as standardized documentation may help ensure that PA more seamlessly achieves its goals of safe and effective use of medications.
