The PACS initiative: what does it take?

Successful implementation of a PACS requires both a technology infusion and a re-engineering of the film-based workflow used for more than 100 years in health care. Because of the sensitivity of a PACS, high-level administrative support is needed to address resistance to change and other roadblocks. A PACS project team must look at how the system will operate not only in the primary imaging department, but also throughout the health care institution. The project plan developed must take into account the technology and workflow changes required, the potential risks to the project, and key milestones that must be met. Frequent ongoing review of the project at a high level is required. Technology enables PACS to improve workflow, and that technology encompasses modalities, networks, diagnostic workstations, archives, interfaces, Web distribution, and other systems (i.e. RIS, HIS). Support from information technology and clinical engineering departments, PACS vendors, modality original equipment manufacturers (OEMs), and third-party software is required. Adopting PACS means dependency on this technology. Improvements realized via PACS become every day expectations; therefore, PACS must have operational support and documented downtime procedures. The potential benefits of PACS-instant, multiple-user accessibility to high-resolution imagery-promise hospitals a significant return on investment.
