Acute confusion is extremely common in hospitalized older adults. One third of general medical patients who are 70 years of age or older have delirium. For more than 30 years, Dr. Sharon K. Inouye has dedicated herself to the identification and prevention of delirium in the hospital. She created the Confusion Assessment Method (CAM), the most widely used method for identification of delirium worldwide. In addition, she is the champion of the Hospital Elder Life Program (HELP).
