RESUMO
PURPOSE: To investigate whether private practice interventional radiology (IR) groups self-report higher overall productivity given differing case mix and more diagnostic radiology interpretation. MATERIALS AND METHODS: A 60-question survey was distributed to 3,159 self-identified US IR physicians via the Society of Interventional Radiologists member search engine, with 357 responses (11.3% response rate). Of these responses, there were 258 unique practices from 34 US states. RESULTS: Out of 84 IR group responses, private practice IR (PPIR) physicians reported a minimal trend for higher annual work relative value units (wRVUs) per clinical full-time equivalent compared with academic IR physicians (8,000 versus 7,140, P = .202), but this did not reach statistical significance. PPIR groups reported fewer median weekly hours (50 versus 52), more frequent call (every 6 versus every 5 days), and significantly higher median tenured compensation ($573,000 versus $451,000, P = .000). Out of 179 responses, academic practices reported significantly higher case percentages of interventional oncology and complex hepatobiliary intervention (P <.001), and private practices reported significantly higher percentages of musculoskeletal intervention (P < .001) with a nonsignificant trend for stroke or neurologic intervention (P = .010). Private practices reported more wRVUs from the interpretation of diagnostic imaging, at 26% of total wRVU production compared with 7% of total wRVU production for academic practices (P < .001; n = 131). CONCLUSIONS: Self-reported data from private and academic IR groups suggest minimally higher wRVUs per clinical full-time equivalent among PPIRs with lower weekly work hours, more frequent call, differing case mix, and significantly higher tenured compensation among PPIR groups.
