The population of people age 80 and older: A sentinel group for understanding the future of health care in the United States

: Those age 80 years or older (80+) constitute a relatively small percentage of a health care system's population. However, because of the associated risks, costs, and variation of their medical care, 80+ patients are sentinel for elder care quality. This article describes the survey components of the 80+ Project. This project was designed to help clinicians gain a complete picture of the special needs of the 80+ population. The information about these patients' health and functional status, how they utilize health care resources, how they obtain access to care, and their satisfaction with the care is useful for clinicians who wish to improve health care delivery.
