Therein lays the challenge: How to best achieve integration of the RIS database with the PACS database. Up to 80% of hospitals already have a RIS in place, and it is usually integrated with a hospital information system (HIS).

With a functioning DICOM modality worklist service, the system virtually eliminates redundant data entry or manual reconciliation of broken studies, another productivity improvement. Moreover, a single-tiered archive supporting a RIS/PACS network can provide access to all radiology images and patient data in real time. In addition, CR shows productivity rate increases in the 10%-12% range. In concert with a RIS and other clinical information systems, images can be integrated with the radiology report and with other patient information systems (such as laboratory, pharmacy, cardiology, and nursing reports).Īccording to PACS consulting firm Integration Resources of Lebanon, NJ, clinical studies show that radiologist and technologist productivity can be increased by 15%-20%, and higher, with a RIS/PACS, especially in CT and MR. Most important, such a system will significantly improve service to patients and referring physicians.Ī PACS enables nearly instant access to images and patient data within radiology, clinical areas in the hospital, and to remote users. When the RIS, PACS, and modalities operate and function as a single system, users can reduce film and chemical costs, reduce film-storage space requirements, and increase productivity due to better utilization of radiology assets.
However, PACS alone cannot deliver the desired results unless it is fully integrated with a DICOM-compatible RIS, as well as a full DICOM interface with imaging modalities.
PACS has proven to be a cost-effective solution for the management and distribution of radiology images for facilities performing thousands to tens of thousands of radiological studies per year. PACS is a necessary tool for hospitals and imaging centers, both to complement digital modalities and to meet increasing productivity demands.
