Individuals at high risk for serious illness are undeniably the most challenging of all patient populations. These people, typically fewer than one percent of patients, account for up to forty percent of actual medical costs - often at the expense of both quality and profitability. To remain competitive, health care organizations must refocus clinical care on managing patients - not providers - and partner with patients, families, and communities to prevent the need for high-cost health care. Status One documents one of the most successful approaches to high risk population health management. The leading architects of this pioneering approach - Samuel Forman and Matthew Kelliher - will assist leaders as they strive to improve qulaity of care, patient outcomes - and the bottom line.
