Existing IR quality improvement metrics can be limited by subjectivity and inconsistent peer-review processes; they focus on procedural complications which may fail to identify physician outliers. This study evaluated and stratified fluoroscopy time and dose as objective quality metrics for provider-assessment. Retrospective review of 228 uterine fibroid embolization (UFE) and 263 transjugular intrahepatic portosystemic shunt (TIPS) cases from 2012-2018, 2 procedures with recognized higher exposure risks, was performed. Patient dose in air kerma (Gy), fluoro time, provider case numbers and years’ post-fellowship user experience were recorded for 8 and 10 providers respectively. UAE complexity were stratified by embolic vial numbers and patient weight. TIPS patients were stratified by portal vein thrombosis (PVT) and concurrent embolization including BRTO, BATO, PARTO. For UFE and TIPS there was a relative trend such that more cases performed yielded lower dose however it did not correlate with years-post fellowship. Median AK among UFE was 1.26 (±1.57) and among standard TIPS was 1.20 (±1.3). Median fluoro time was 28.3 (±29.8) and 32.5 (±5.9) mins respectively. For TIPS without PVT or concurrent embolization there were two high-dose outliers defined as those greater than one standard deviation away from the median. For UFE there were two high-dose outliers. When comparing dose to BMI for UFE, a common reason for increased dose, there is a general upward trend however with relatively low correlation (r2 = 0.33). Patient dose, stratified by key procedural elements can be used as reproducible quality metric in high-dose procedures. Provider experience and number of cases did not correlate with lower patient dose. These metrics may be objectively useful to identify and benchmark individual provider performance and highlight outliers; it can identify providers who may benefit from improved radiation awareness and procedure specific training. This has the potential for timely provider level assessments and warrant validation on a larger multi-institutional national scale.Tabled 1UAEAttendingYears Post-FellowshipNumber of Cases PerformedMedian Fluoro Time (min)Median Air Kerma (Gy)IR 121234.803.50IR 233528.331.57IR 352733.100.85IR 492134.172.34IR 5103825.551.26IR 614548.172.38IR 7185730.251.13IR 823339.002.98IR 9264517.550.76IR 10301927.880.41Average31.951.64Median28.271.26SD29.841.57Noncomplicated TIPSYears Post-FellowshipNumber of CasesMedian Fluoro Time (min)Median AK (Gy)IR 11429.750.92IR 231227.101.11IR 351030.101.23IR 4104028.520.88IR 5141143.000.64IR 6181038.072.31IR 7231036.202.41IR 8266327.320.87Average32.511.56Median31.251.20SD5.861.34 Open table in a new tab
