Evaluation of incidental adrenal masses at a tertiary referral and trauma center

Background: Incidental adrenal masses are those that are found on imaging performed for any non-adrenal evaluation. Published guidelines define accepted follow-up criteria for incidental adrenal masses; however, adherence to these guidelines and barriers to appropriate follow-up are not well understood. We aimed to describe practice patterns for the discovery, evaluation, and follow-up of incidental adrenal masses. Methods: Medical records of patients with an incidental adrenal mass underwent retrospective review at a tertiary referral and level-1 trauma center, as well as regional ambulatory care locations. Individuals >= 18 years of age with an incidental adrenal mass identified during 2016 were included. Patterns of evaluation, follow-up, and associated adrenal diagnoses were determined. Results: From a total of 19,171 cross-sectional imaging procedures (computed tomography and magnetic resonance imaging), 244 patients with new incidental adrenal masses were identified. A majority (52%) were discovered as part of an evaluation in the emergency department. Of 153 patients with an identifiable primary care provider, approximately 75% had an in-network primary care provider, and 12 (7.8%) had both follow-up imaging and biochemical evaluation. Twenty-three percent of patients with an in-network primary care provider underwent an appropriate cross-sectional imaging procedure in follow-up compared to 29% for a non-network primary care provider (P = .54). Patients with a mass described with benign terminology were less likely to undergo follow-up imaging compared to those with indeterminate terminology (5% vs 37%, P < .001). Patients with imaging ordered as an outpatient were more likely to receive follow-up with imaging (22.8% outpatient vs 11.5% inpatient, P = .042). There was no difference between any groups regarding biochemical evaluation, which inappropriately was performed in only 15% of patients with an incidental adrenal mass. Conclusion: To optimize follow-up of incidental adrenal masses, efforts should be made to assure and prioritize inpatient/emergency department incidental findings and to communicate to the appropriate primary care provider the necessary next steps for evaluation. Further, efforts to increase biochemical testing should be pursued. (C) 2019 Elsevier Inc. All rights reserved.
