Validation of the JEN frailty index in the National Long-Term Care Survey community population: identifying functionally impaired older adults from claims data.

ABSTRACT:

Background

Use of a claims-based index to identify persons with physical function impairment and at risk for long-term institutionalization would facilitate population health and comparative effectiveness research.
