Trends of Follow-Up Recommendations Made on Musculoskeletal MRI Reports.

The purpose of this article was to analyze trends in follow-up recommendations made on musculoskeletal MRI reports. An IRB-approved retrospective study identified 790 musculoskeletal MRI reports from our database between January 1, 2016, and January 1, 2018, containing follow-up recommendations made by the interpreting radiologist. Metadata were automatically extracted and classification of the recommendations was performed by manual review. Clinical outcome data were collected from the electronic health record. After exclusion criteria were applied, 654 reports were included in the study. Descriptive statistics, Fisher exact tests, and chi-square tests were used for analysis. Clinicians acknowledged 83% and followed 73% of the recommendations. Follow-up compliance varied with the type of recommendation made: 98% for clinical intervention versus 67% for additional imaging ( < 0.001). Subspecialties acknowledged and followed recommendations at different rates: 92% and 85% for internists versus 76% and 64% for orthopedists ( < 0.001 and < 0.001), respectively. Patient age, practice setting, radiologist experience, recommendation conditionality, and specified follow-up time intervals made no difference in compliance rate (all > 0.05). There was no difference in compliance rate among various pathologic findings of concern ( = 0.995). Compliance rate increased significantly after direct communication between the radiologist and clinician compared with when there was no direct communication (93% vs 71%, < 0.001). Concern for neoplasm comprised the greatest number of unacknowledged recommendations (73%). Musculoskeletal MRI recommendations are followed independent of the finding of concern and compliance is lowest for requests of additional imaging. Direct communication improves compliance and may be particularly helpful for orthopedic referrers.
