CT scans came six days sooner after Annalise Enterprise CXR arrived

SHTG found that NHS Grampian patients got CT scans six days sooner once Annalise Enterprise CXR triaged chest X-rays, with extra staff and CT slots. Other gains were not statistically significant.

  • 1 a person

    Patients who needed a CT scan got it six days sooner after their X-ray report, while the changes in time to treatment and stage at diagnosis were not statistically significant.

  • Not rated an organization

    SHTG found that the changes helped radiology staff prioritize their workload, but it gives no measure of the gain and found that the pathway cost more.

Depth runs from 1, a convenience or time saved, to 5, a life or a livelihood preserved.

Compared with

A 2019 baseline of clinical review without the software (n=113). Measured.

The system’s part
Not isolated. SHTG compared a 2019 baseline with the year after NHS Grampian added the software, extra reporting, a coordinator and protected CT slots. It writes that changes made at the same time make it difficult to tell the effect of each one. SHTG states that the software uses a machine learning model trained on over 820,000 chest X-ray images.

    All patients who needed a CT scan (n=68) received a CT scan six days more quickly following a CXR report, which was statistically significant (95% confidence interval (CI) [3.647,7.369], p<0.001).

Details

AI system

Workflow

The software flagged chest X-rays at elevated risk of lung cancer for urgent reporting by radiologists. A coordinator arranged urgent CT scans for patients whom radiologists judged to be at high risk. NHS Grampian protected 20 CT slots a week for the urgent pathway.

Follow-up

Conditions for replication

The software's calibration matches the staff and CT capacity of the pathway. A clinician reviews every flagged X-ray before a CT scan is arranged.

Entry details

Sector

Healthcare (lung cancer diagnosis).

Purpose
