An assessment of the association between patient race and prior authorization program determinations in the context of radiation therapy.

Background: When a physician determines that a patient needs radiation therapy (RT), they submit an RT order to a prior authorization program which assesses guideline-concordance. A rule-based clinical decision support system (CDSS) evaluates whether the order is appropriate or potentially non-indicated. If potentially non-indicated, a board-certified oncologist discusses the order with the ordering physician.

Characterizing Cardiac Catheterization Utilization in a US Population with Commercial or Medicare Advantage Health Plans.

Background: Health plans and health systems need to understand the demand for common healthcare services to ensure adequate access to care. Utilization of cardiac catheterization is of particular interest, because it is relatively common and has the potential for variation across subpopulations, similar to the level of geographical variation in heart disease in the United States.

Objectives: To illustrate how the utilization of cardiac catheterization has changed over time in a US population with commercial and Medicare Advantage health plans, and how it differs between subpopulations.

A Description of Outcomes Experienced by Patients Whose Orders for Peripheral Artery Revascularization Were Reviewed by a Nondenial Prior Authorization Program.

Objective: After a nondenial prior authorization program evaluates orders for peripheral artery revascularization (PAR), ordering physicians sometimes withdraw their orders based upon program recommendations. Some patients with withdrawn orders receive PAR if claudication does not resolve. To characterize patient outcomes under this program, we evaluated whether associations existed between the withdrawal of patients' initial PAR orders and the presence of claims for PAR and claims mentioning intermittent claudication (IC) in the following 16 weeks.

Modification and Reinitiation of Lower Back Imaging Orders After Evidence-Based Collaborative Consultation.

Rationale And Objectives: Practice guidelines suggest most patients should wait at least 28 days from the onset of low back pain before receiving imaging. This study evaluates a nondenial prior authorization program's performance in modifying lower back imaging orders. Ordering physicians were asked by a consulting physician to modify any order that did not meet guidelines through collaborative consultation.
