Cardiac picture archiving and communication systems and telecardiology - technologies awaiting adoption.

Diagnostic and therapeutic procedures associated with cardiology are heavily supported by diagnostic imaging technology. The management of such images, including radiographs, echocardiography examinations and cardiac angiography studies, requires a suitable means of handling the data. A number of manufacturers are now offering picture archiving and communication systems (PACS) and telecardiology options. These could greatly improve the efficiency of data management for cardiac examinations, including linkage to radiology and hospital information systems and electronic patient records. A barrier to the implementation of cardiac PACS has been the relatively high capital cost. There have also been technical difficulties in implementing a suitable interface. Historical problems have included 'turf wars' between different specialist groups and a reluctance to shift from well established practice patterns. Early cooperative work between radiologists and cardiologists in the development of coronary arteriography has been replaced by contention between cardiologists, radiologists and vascular surgeons, often driven by economic considerations rather than the needs of the patient. At this stage, cardiac PACS and telecardiology have great potential for improving the coordinated care of cardiac patients in Australia.
