Functional status and health status.

Abstract

Functional status assessment originated in clinical practice in rehabilitation. Health status assessment, a growing part of health services research, grew from the need to survey the health of large populations. In spite of many common interests, the two fields have had little cross-fertilization. The origins and current status of health status measurement are described, including examples of the most frequently used instruments. Conceptual and methodological issues shared by the two fields are examined with the aim of determining what might be of value to rehabilitation. Health-related quality of life provides a conceptual framework that could broaden the rehabilitation perspective. Health status measures may not be appropriate for clinical management but might be useful as quality of care and outcome indicators.
