Decision Precision+


Lung cancer is the leading cause of cancer deaths, and lung cancer screening through low-dose CT scans could save more lives than breast cancer screening. However, only about 5% of eligible Americans are screened each year. An important reason for this lack of appropriate screening is that lung cancer screening requires the review of patient-specific benefit and risk information using a decision aid, but such shared decision making is cumbersome without effective decision support tools integrated with the EHR.


Decision Precision+ is an EHR-integrated decision aid that provides individualized benefit and risk information using state-of-the art risk models from the National Cancer Institute. It is seamlessly integrated with the EHR and enables high-quality shared decision making in busy clinical settings. After deployment at University of Utah Health, the rate of lung cancer screening increased significantly (manuscript in process).


Decision Precision+ is a SMART on FHIR applications that pulls in a wide range of relevant data from the EHR and provides patient-specific guidance on benefits and risks.  The tool uses the U.S. Preventive Services Task Force guidelines to determine which patients should be considered for lung cancer screening, then uses lung cancer risk and life expectancy models from the National Cancer Institute ( to provide patient-specific benefit and risk information. Further guidance on whether screening has high net benefit or is preference sensitive is provided based on work published by Caverly et al. in the Annals of Internal Medicine.

A stand-alone version of the tool, known as Decision Precision, is available to all at The EHR-integrated version of the tool is also being made available for free through EHR app stores.

The initial development of the standalone Decision Precision tool was funded by the Veterans Administration, with the work led by Dr. Tanner Caverly and Dr. Angie Fagerlin.  The subsequent conversion of the tool into the EHR-integrated Decision Precision+ tool was funded by the Agency for Healthcare Research and Quality (R18 HS026198), with the work led by Dr. Kensaku Kawamoto.
