Implementation of Incidental Liver Lesion Clinically Integrated Workflow Increases Compliance With ACR Follow-Up Guidelines, Closing Care Gaps

Abstract

Objective: Follow established management guidelines from the ACR and improve adherence to follow-up recommendations for incidental liver lesions (ILLs) for all patients undergoing CT abdomen and pelvis with contrast (CTAPw) examinations, with advocacy from a multidisciplinary care team.

Methods: A mandatory structured radiology reporting module was developed for use in CTAPw reports for ILL recommendations. Data from the electronic medical record describing patients with radiology-reported ILLs and their clinical risk diagnosis categories were tabulated in a queryable electronic database. A nurse co-ordinator initiated workflow to communicate the need for ILL follow-up MRI to ordering physicians and primary care providers. MRIs were ordered by the ILL team. An interactive process was undertaken with continuous review to improve identification of eligible patients and adherence to recommendations.

Results: During the initial launch phase from December 2020 to March 2021, 1,577 ILLs were detected on 20,667 CTAPw examinations, and for those with the characterize now recommendation, 36 of 114 (31.6%) received follow-up in 30 days. Between January 2021 and June 2022, 117,520 CTAPws were performed and 4,371 ILLs were detected. Using the ILL workflow, in the MRI now cohort, follow-up occurred within 30 days in 202 of 542 (36.2%) patients, and a total of 368 of 542 (67.9%) patients have completed their follow-up to date.

Discussion: Using a focused effort to close a gap in ILL care, adherence to follow-up recommendations improved over the long term, although there remains a gap in adherence to short-term interventions. A multidisciplinary approach, radiology reporting, and software solutions were leveraged to improve a complex process.
