Introduction: Since 1968, we have over a million ECGs in our regional computerized ECG Processing Center. We have previously reported the performance and clinical evaluation of our IBM/Bonner ECG analysis and comparison programs and currently our Hewlett Packard analysis and comparison programs.
We have previously reported system analysis of ECGs, influence of editing on performance, inter- and intraobserver variability in ECG interpretation by family practitioners, internists, and cardiologist.
Our central work station now allows us to acquire the ECG, analyze, and compare it to all previous electrocardiograms in the past five years. Central editing and storage can be done without exiting the system or paper production.
The edited compared analysis and wave form can be retrieved and displayed at any terminal throughout the health system via our Novell Network and backbone. All unit records can be made available on-site by a laser printer if needed.
A detailed cost analysis demonstrates a saving in paper, handling, storage, and retrieval in excess of $250,000 a year. The edited turnaround time can be reduced to a few hours. The emergency ECG can be over-read by the on-call cardiologist from any terminal in the system and at their home. The on-line compared and edited current ECG is essential to qualify health care, cost containment and risk management.
