Accurate data on CMR practice patterns is a prerequisite for planning strategies to grow clinical volumes within existing CMR clinical services, increase the number of hospitals that offer these services, and improving reimbursement.
Data analysis was performed on a cloud-based system that is currently receiving de-identified searchable data from electronically-signed clinical reports with full DICOM datasets for 23,275 consecutive CMR exams performed at four geographically diverse U.S. medical centers from Jan 1, 2010 through Dec 31, 2014. At the time of abstract submission, 8,242 datasets have been analyzed, and analysis of all 23,275 is expected by the end of 2015. All data fields were derived from CMR reports that had been electronically signed by board-certified physicians with Level 3 CMR training. We analyzed: 1) patient characteristics and clinical indications for CMR scans; 2) use and complication rates for contrast agents; 3) use and complication rates for stress testing; and 4) billing data based on CPT codes.
CMR is clinically viable in the United States with the most common indications: heart failure/cardiomyopathy, ischemia evaluation, vascular disease, and valve assessment. CMR vasodilator stress testing appears remarkably safe in clinical practice.
