Evaluation of vascular and interventional procedures with time-action analysis: a pilot study

Area of Science:

• Medical Imaging and Interventional Radiology
• Healthcare Efficiency and Workflow Analysis

Background:

• Vascular and interventional procedures require efficient workflow for optimal patient outcomes.
• Objective metrics are needed to evaluate and improve the performance of these complex medical interventions.

Purpose of the Study:

• To introduce and validate the time-action analysis method for measuring the efficiency of peripheral vascular and interventional procedures.
• To establish a standardized taxonomy of actions within these procedures for consistent data collection.

Main Methods:

• Defined a time-action analysis method and a specific taxonomy of actions (e.g., navigate, image, treat, exchange).
• Described recording methods and analysis techniques for time-action data.
• Analyzed 30 peripheral vascular and interventional procedures to demonstrate data acquisition and application.

Main Results:

• Detailed breakdown of time allocation across various procedural actions.
• Puncture site compression accounted for the most time (18.5%); exchanges were most frequent (20.4 times/procedure).
• Identified specific phases, such as imaging preparation (5.2%-8.3% radiation exposure), for potential radiation dose reduction.

Conclusions:

• Time-action analysis provides an objective, quantifiable method for monitoring and evaluating vascular and interventional procedures.
• The technique offers insights into workflow inefficiencies and potential areas for improvement, including radiation exposure reduction.
