Analog to digital workflow improvement: a quantitative study

Area of Science:

• Radiology
• Medical Imaging Technology
• Healthcare Workflow Optimization

Background:

• Radiology departments traditionally relied on analog imaging systems.
• The transition to digital radiography (DR) offers potential improvements in efficiency and image quality.
• Evaluating the quantitative impact of system conversion is crucial for healthcare management.

Purpose of the Study:

• To assess the workflow and productivity changes after a radiology department converted from an analog to a digital radiography system.
• To quantify the impact of the Kodak DirectView DR 5100 system on patient examination times and repeat rates.
• To demonstrate the utility of simulation software in analyzing clinical workflow.

Main Methods:

• Workflow simulation using ProModel Optimization Suite.
• Quantitative analysis of process data before and after system conversion.
• Measurement of average patient examination time and modality-specific activity durations.

Main Results:

• Average patient examination time decreased from 9.24 to 5.28 minutes.
• Chest examination time was reduced by 43% for modality-specific activities.
• The percentage of repeat examinations decreased from 9.5% with the analog system to 8% with the digital system.

Conclusions:

• Digital radiography systems can significantly enhance radiology department efficiency and patient throughput.
• Workflow simulation software provides valuable quantitative insights into clinical process improvements.
• The transition to digital systems leads to reduced examination times and fewer repeat procedures, optimizing resource utilization.
