Trust But Verify: Online Management Tool Improves Compliance and Documentation of CT Quality Control Activities.
J Am Coll Radiol. 2018 May;15(5):762-766. doi: 10.1016/j.jacr.2017.11.011. Epub 2017 Dec 21. Duong PT1, Neill R2, Zygmont M3.
CT quality control (QC) requirements have become more stringent, driven by increasing equipment complexity and awareness about medical radiation. To meet Joint Commission compliance regulations and maintain ACR accreditation 1, 2, daily, monthly, and annual QC checks must be performed and documented for CT scanners. However, documenting compliance in an easily accessible way for regulatory audits is challenging. Also, quarterly review by our physicist could lead to a delay of as much as 3 months in recognizing subtle aberrant results if they were missed by the technologist.
Many institutions, including ours, use paper-based QC logs, which are reviewed and acknowledged by a physicist. Large health systems face the challenge of physicists covering multiple scanners or modalities at different locations. Smaller hospital systems may not have a full-time physicist and contract with a medical physics service. These geographic and personnel constraints also increase the likelihood of an unrecognized defect, depending on the interval of review.
