Summary

Implementing a relay station in Picture Archiving and Communication Systems (PACS) nearly eliminated demographic errors for computed tomography (CT) examinations. Technologists reported improved workflow, quality control, and routing, with faster task completion times.

Area of Science:

  • Medical Imaging
  • Health Informatics
  • Radiology Workflow Optimization

Background:

  • Distributed Picture Archiving and Communication Systems (PACS) environments often face challenges with demographic discrepancies and inefficient image routing.
  • Quality control (QC) and technologist workflow can be negatively impacted by manual data handling and routing errors in existing PACS.

Purpose of the Study:

  • To evaluate the impact of a relay station on demographic errors, image segmentation, QC, and technologist workflow within a computed tomography (CT) PACS environment.
  • To assess the scalability and cost-effectiveness of a relay station compared to dedicated QC workstations.

Main Methods:

  • A retrospective evaluation of a CT PACS environment before and after implementing a relay station.
  • Assessment of demographic error rates and study routing accuracy using statistical analysis (chi-square test).

  • Technologist perceptions of workflow factors, user interface, and training needs were gathered via questionnaire.

    • Main Results:

    • The demographic error rate for CT examinations decreased significantly from 14.0% to 0.55% post-relay station deployment (P < .001).
    • A majority of technologists reported positive impacts on correcting demographic errors (90%), facilitating QC (67%), and ensuring proper routing (77%).
    • Task completion times were reduced with the relay station (1-5 minutes) compared to film handling (2-15 minutes).

    Conclusions:

    • Relay station deployment prospectively eliminates demographic errors and effectively segments images for routing to different workstations.
    • The relay station integrates seamlessly into existing technologist workflows, offering a scalable and cost-effective solution.
    • Technologists found the user interface intuitive and preferred the relay station over film handling, recommending combined didactic and hands-on training.
