Frailty: the next stage of chronic disease?
Hospitalization, Restricted Activity, and the Development of Disability Among Older Persons
• Cohort– March 1998 and October 1999– potential participants were identified from a computerized list of 3157
age-eligible members from a large health plan in greater New Haven– screening telephone interview – in-home assessment.
• Physical frailty– Timed score of greater than 10 seconds on the rapid gait test (ie, walk
back and forth over a 10-ft [3-m] course as quickly as possible)– In the absence of a criterion standard, operationalizing physical frailty as
slow gait speed is justified by:• High face validity• Clinical feasibility• Strong epidemiological link to functional decline and disability
