What closing the gap would mean

If screening in these counties rose from 16.4% to the national rate of 18.2%, about 2,200 to 3,700 more people would be screened each year.

In the National Lung Screening Trial, low-dose CT screening lowered lung cancer deaths by 20% compared with chest X-ray. Today about 71% of lung cancers here are found at a late stage.

Illustrative estimate: eligible adults (range) times the change in screening rate. Not a forecast or a guarantee.

Screening at Franciscan Missionaries of Our Lady Health System today

Clinicians at Franciscan Missionaries of Our Lady Health System locations billed 453 low-dose CT lung screening reads to Medicare fee-for-service in 2024. Including Medicare Advantage and other insurers, we estimate about 980 to 2,800 screenings a year.

Most adults who qualify see a primary care clinician every year. We count 1,449 primary care clinicians, 31 pulmonologists and 22 thoracic surgeons practicing at Franciscan Missionaries of Our Lady Health System locations. A 20 pack-year smoking history is often missing from structured EHR fields, so many eligible patients are never flagged.

CMS Medicare Physician and Other Practitioners 2024 (CPT 71271); clinicians matched to Franciscan Missionaries of Our Lady Health System by practice address using the AHRQ Compendium of U.S. Health Systems 2023, so reads billed by outside radiology groups are not included. The all-payer estimate scales Medicare fee-for-service by the local Medicare Advantage share (54%, CMS) and, at the high end, by the share of eligible adults under 65 (65%).

LungIQ Find

Reads clinical notes, diagnoses and medications in the EHR and returns a ranked list of patients likely eligible, including those whose pack-year history is missing. Start with a CSV export refreshed every 1, 3 or 6 months, or connect through FHIR or HL7.

LungNAV Reach

An AI patient navigator that texts and calls patients in 70+ languages, answers questions about the scan, and hands each patient to your scheduling team or nurse navigators with a call summary.

LungAI Second opinion

Gives radiologists a malignancy risk score for each nodule, factoring in change since the prior scan, inside the PACS and CADe software they already use. The radiologist makes the final call.

LungAI is an investigational medical device and has not been cleared by FDA. It is not commercially available in the United States.
