Use of a Commercially Available Clinical Decision Support Tool to Expedite Prior Authorization in Partnership With a...

The aim of this study was to determine if a clinical decision support (CDS) tool could be used in partnership with a private payer to successfully expedite the prior authorization process for advanced (ie, MRI, CT, PET, nuclear medicine) imaging requests.

A single academic institution integrated a commercially available CDS tool utilizing the ACR Appropriateness Criteria into the ordering process for outpatient advanced imaging tests within the electronic health record. Ordering providers could elect to use the CDS tool or ignore the available technology. In partnership with a health care insurance company and a contracted radiology benefits management company, orders deemed as "usually indicated" by the CDS tool underwent expedited prior authorization in a pilot program from June 2018 to October 2019.

Providers used the CDS tool for 15% (1,453 of 9,640) of outpatient advanced imaging orders. Of these orders with elective CDS scores, 69% (n = 997) qualified for an expedited prior authorization process.

Under specific circumstances, a commercially available CDS tool was used in partnership with a private payer and a radiology benefits management company to expedite prior authorization of outpatient advanced imaging examination orders deemed likely to be appropriate by multispecialty professional guidelines.
