The Florida Cardiovascular Quality Network (FCQN) is a quality outcomes registry. In a diverse group of clinical sites in Florida, a large number of patients with known or possible stable ischemic cardiovascular disease (SIHD) referred for cardiovascular stress test will be enrolled in this quality demonstration registry. This registry is based on the hypothesis that evidence-based clinical guidelines and appropriate use criteria (AUC), when provided at the site and time of care (point of care), may improve physician clinical decisions and, thus, the overall quality and value of care for individual patients and populations. Specifically, this study registry will utilize multiple proven software tools at the point of care: (1) Seattle Angina Questionnaire (SAQ) as the method of measurement of patient angina symptoms; (2) FOCUS, American College of Cardiology (ACC) software to provide clinical decision support (CDS) as the primary method of determination of AUC in patients with a clinical indication for a cardiovascular stress test; (3) CATH/PCI, ACC / National Cardiovascular Data Registry (NCDR) to provide clinical decision support as the primary method of determination of AUC in the cardiac catheterization laboratory; (4) PINNACLE, ACC/NCDR clinical registry to provide an extensive database of clinical quality metrics; and (5) ACC CARDIOSMART software modules as the primary patient education tool for effective risk factor modification. The application of these clinically proven software tools, all applied at the point of patient care, may assist physician compliance with ACC guideline based AUC and may directly result in an increase in SIHD patients treated with guideline directed medical treatment as well as guideline directed interventional treatment. It is anticipated that this increased compliance with ACC guidelines and AUC may directly correlate with improved patient clinical outcomes.
