A polar diagram for comprehensive geriatric assessment.

Comprehensive geriatric assessment has become synonymous with geriatric practice. This includes evaluation of the older person's physical and mental health, and the functional and social status. We propose a new way of representing a person's condition, called the "polar diagram". This shows the subject's scores on the evaluation scales that are arranged in radial positions inside a circle. The outer part of the circle corresponds to the best condition. Gaps between the best condition and the actual scores are easily identified. The diagram can be employed to monitor the subject's condition and to assess any changes in outcomes.
