Abstract
Healthcare in the USA is struggling with alarming levels of hospital readmission. Cardio Vascular Disease (CVD) has been identified as the most frequent cause. While the factors related to high hospital readmission are complex, according to prior research, early detection and post-discharge management has a significant positive impact. However, the widening gap between the number of patients and available clinical resources is acutely aggravating the problem. A solution that can effectively identify well patients at risk of future CVDs will allow focusing limited clinical resources to a more targeted set of patients, leading to more widespread early detection, prevention and disease progression management. This in turn, can reduce CVD-related hospital readmissions. Moreover, if the patient data required by such a solution can be collected without any blood test or invasive procedure, the addressable patient population can be vastly expanded to include home care, remote, and impoverished patients while delivering cost savings of the invasive procedures. Using a Design Science Research (DSR) approach, this research has led to the design and development of a machine learning based predictor artifact capable of identifying patients with future CVD risks. The performance of this predictor artifact, as measured by the area under the receiver operating characteristic (ROC) curve, is 0.859. The sensitivity or recall is 85.9% at probability threshold of 0.5. The significant differentiating feature of this artifact lies in its ability to do so without any blood test or invasive procedure.
