Description: Most health care delivered in the United States is based on the acute care model: it is episodic has a beginning, middle and end usually the patient recovers and interventions are designed to target a specific pathophysiologic abnormality. Chronic disease care, in contrast, often has no clear beginning and no end the focus is on managing over the long term with prevention of progression and complications. Further, many chronic diseases “travel together” comorbidities: for example, diabetes, hypertension, coronary artery disease CAD, heart failure, cerebrovascular disease, peripheral arterial disease and renal dysfunction are often found together.
