Prior authorization in gynecologic oncology: An analysis of clinical impact

Prior authorization was designed to minimize unnecessary care and reduce spending but has been associated with delays in necessary care. Our objective was to estimate the occurrence of prior authorization, and impact on cancer care, in gynecologic oncology.

We performed a retrospective cross-sectional study of patients seen in University of Pennsylvania gynecologic oncology practices (January-March 2021). Using electronic medical records, we measured the incidence of prior authorization during the 3-month period and prior experience of prior authorization for cancer care overall and by type of order (chemotherapy, imaging, surgery, prescription drugs). We assessed the impact of prior authorization occurrence on clinical outcomes (time to service, changes in care).

Of the 2112 clinic visits of 1406 unique patients, 5% experienced prior authorization during the 3-month study period. An additional 20% faced prior authorization requests earlier in cancer care. Of the 83 prior authorization requests, imaging accounted for the majority (54%) followed by supportive medications (29%) and chemotherapy (17%). After appeal, 79% of cases were approved. For patients whose prior authorizations were approved, there was a mean of 16 days from order placement to care delivery (95% CI 11-20, range 0-98 days). Of the 17 denials, 3 (18%) led to a substantial change in care (i.e., not receiving planned treatment).

25% of gynecologic oncology patients experienced prior authorization during their cancer care. While 80% of claims were ultimately approved, patients experienced over a 2-week delay in care when prior authorization occurred. Reform is needed to reduce the burden of prior authorization in oncology.
