The very old patient in ambulatory care.
The aims were twofold: to determine differences between the very old and younger patients in ambulatory care and to examine their self-assessments of health and whether these related to: subjective data such as symptoms and attitudes, objective data such as utilization of health services, and physician assessments of the patient's health. Although they had about one more diagnosis, the very old were similar in most respects to younger patients. Variables that discriminated the groups were physician ratings. About two-thirds of the older and younger patients regarded their health as good. Good health perceptions were associated with fewer symptoms, outpatient visits, and hospitalizations in both groups. Physician assessments were only lowly correlated with patient assessments of health. Patient perceptions of health were highly stable over a two month follow up. The subjective belief that one is healthy or ill may be more important than actual medical condition in maintaining good emotional and behavioral functioning.
