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

Abstract

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 (TRoom) and total encounter (TEncounter) 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 TRoom 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 TRoom when performed via Angio-CT compared to control (99 vs. 163 min, p < 0.0001). There was a significant reduction in TEncounter 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 < 0.001 and 231 min vs. 347 min, p < 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 TRoom and TEncounter for specific non-complex bundled cases.
