User satisfaction with picture archiving and communication systems (PACS) decreased, primarily due to slow image retrieval times. Improving PACS workstation response times is crucial for enhancing user experience and system quality.

Area of Science:

  • Medical Imaging Informatics
  • Health Systems Engineering

Background:

  • Picture Archiving and Communication Systems (PACS) are integral to modern medical imaging workflows.
  • Evaluating user satisfaction and system usage patterns is essential for optimizing PACS performance.

Purpose of the Study:

  • To assess the utilization of a PACS and gauge user satisfaction to identify areas for quality improvement.
  • To analyze user demographics, access patterns, and satisfaction levels across different hospital departments.

Main Methods:

  • A prospective study was conducted at a medical college hospital in Japan.
  • Automated data collection from March 1999 to February 2000 captured workstation usage, user rank, purpose, postprocessing tool use, and satisfaction.
  • Statistical analysis compared usage and satisfaction between users inside and outside the radiology reading room.

Main Results:

  • Resident user numbers increased in the reading room but decreased outside; staff user numbers remained stable.
  • Image access varied significantly by department, with lower usage in orthopaedic surgery clinics and wards.
  • Overall user satisfaction declined, with significantly lower satisfaction reported by users in the reading room compared to outside (P=0.004).
  • The primary cause of dissatisfaction was the time taken to retrieve images.

Conclusions:

  • Reducing PACS workstation response times is critical for improving user satisfaction.
  • Continuous data collection and evaluation are necessary for ongoing PACS quality enhancement.
