Heart diseases such as acute myocardial infarction and heart failure are the cause of significant morbidity and mortality in the United States. The quality of care and follow up instructions received by these patients of AMI and HF can play an important role in the prognosis and rehospitalizations of these patients. To deliver optimal care to patients, the Joint Commission on Accreditation of Healthcare Organizations included core measures for AMI and HF as part of their ORYX initiative as indicators of hospital performance and compliance in meeting the quality-of-care criteria. This project shows usage of Midas+ information systems and querying and reporting tools such as Microsoft Access and Crystal Reports for evaluating hospital performance for JCAHO core measurements of AMI and HF.
