Hybrid CT-angiography (Angio-CT) for combined CT and fluoroscopic procedures in interventional radiology enhances utilization

Purpose To investigate the utilization of an angiography-CT (Angio-CT) system and its advantages for single patient encounters. Methods Interventions utilizing both CT and fluoroscopy to perform multiple procedures in a single encounter or single interventions using both were identified. Cases were...

description Purpose To investigate the utilization of an angiography-CT (Angio-CT) system and its advantages for single patient encounters. Methods Interventions utilizing both CT and fluoroscopy to perform multiple procedures in a single encounter or single interventions using both were identified. Cases were stratified by complexity (defined by RVUs). Comparative analyses of room ( T Room ) and total encounter ( T Encounter ) times were performed between non-complex bundled cases and controls. Results Between June 2018 and August 2019, 1108 procedures were performed via the Angio-CT system; 10% (114/1108) used both fluoroscopy and CT. 21% (24/114) Involved more than one procedure in a single encounter that required a CT-only and fluoroscopy-only bundled procedure. 59% (67/114) were non-complex, and 70% (80/114) were non-oncologic. 82.5% (14/17) of non-complex bundled procedures demonstrated T Room below the mean of their respective controls; 52.8% (9/17) were 2 standard deviations below the control means. Pleural catheter placement following post-lung biopsy pneumothorax was the most common non-complex bundled case with a significant reduction in T Room when performed via Angio-CT compared to control (99 vs. 163 min, p

There was a significant reduction in T Encounter for abdominopelvic drain placement procedures bundled with either (1) percutaneous nephrostomy tube evaluation with or without replacement, or (2) central venous catheter placement (211 min vs. 344 min, p  &lt; 0.001 and 231 min vs. 347 min, p  &lt; 0.05, respectively). Conclusion The primary use for the hybrid Angio-CT system was to perform non-oncologic and non-complex cases with potential reduction in T Room and T Encounter for specific non-complex bundled cases.
