Time to Talk: Can Radiologists Improve Follow-Up of Abdominal Imaging Findings Indeterminate for Malignancy by Initiating Verbal Communication?

Abstract

PurposeThe aims of this study were to examine the association between radiologist-initiated verbal communication for abdominal imaging findings indeterminate for malignancy and receipt of relevant outpatient follow-up imaging and to evaluate the proportion of findings that progress from indeterminate to suspicious for malignancy. MethodsUsing a mandatory standardized assessment coding system, 727 eligible outpatient abdominal CT, MRI, and ultrasound studies performed between July 1, 2013, and January 31, 2014, were identified. Multivariate logistic regression was used to evaluate the association between radiologist-initiated verbal communication and receipt of relevant outpatient imaging follow-up, adjusted for patient, ordering physician, interpreting radiologist, and imaging variables. ResultsSixty-two percent of patients (451 of 727) with imaging findings indeterminate for malignancy received relevant outpatient imaging follow-up. Radiologist-initiated verbal communication occurred in 4.8% of cases (35 of 727). Radiologist-initiated verbal communication (odds ratio [OR], 2.45; 95% confidence interval [CI], 1.02-5.87) and existing cancer diagnosis (OR, 3.00; 95% CI, 2.11-4.26) were associated with a higher likelihood of receiving relevant imaging follow-up. Compared with those whose imaging studies were ordered by clinicians in a medical specialty, patients with studies ordered by clinicians in surgical (OR, 0.70; 95% CI, 0.49-0.99) or other (OR, 0.44; 95% CI, 20.24-0.83) specialties were less likely to receive relevant imaging follow-up. Progression of findings from indeterminate to suspicious for malignancy occurred in 5.4% of cases and was not associated with radiologist-initiated verbal communication. ConclusionsRadiologist-initiated verbal communication increases the likelihood that patients receive outpatient imaging follow-up for abdominal findings indeterminate for malignancy. Progression of these findings is relatively infrequent.
