Picture archiving and communication system-asynchronous transfer mode network in a midsized hospital

Area of Science:

• Medical Informatics
• Radiology Information Systems
• Picture Archiving and Communication Systems (PACS)

Background:

• Describes the implementation of a hospital information system-picture archiving and communication system-wide area network (HIS-PACS-WAN) in a 300-bed acute care hospital.
• Details the integration of digital imaging (CT, MR, nuclear medicine, ultrasonography) and manually digitized radiographs into an Olicon archive.
• Outlines the use of a wide area network (WAN) for teleradiology and teleconferencing among multiple medical centers.

Purpose of the Study:

• To detail the pathway for full implementation of an HIS-PACS-WAN in a hospital setting.
• To establish a system for storing, retrieving, and displaying medical images alongside physician reports.
• To facilitate teleradiology and teleconferencing capabilities across linked medical centers.

Main Methods:

• Phase I: Design and installation of a local area network (LAN) in the Radiology Department, including fiber-optic infrastructure.
• Phase II: Linking Olicon workstations to imaging equipment, facing significant delays.
• Implementation involved direct digital capture and manual digitization of various imaging modalities.

Main Results:

• Successful installation of LAN and initial PACS archiving capabilities.
• Significant implementation delays in Phase II due to inadequate needs assessment and vendor DICOM incompatibilities.
• The ultimate goal of simultaneous image and report display was pursued.

Conclusions:

• Successful HIS-PACS-WAN implementation necessitates an in-depth, annually updated needs analysis with emphasis on clinical and hospital-wide integration.
• Addressing forward-compatibility and vendor DICOM conformance is critical for PACS projects.
• Integration of PACS, HIS, RIS, and dictation systems requires a dedicated, clinically-oriented project officer.
