Johns Hopkins Frailty Assessment Calculator
Introduction: The Johns Hopkins Frailty Phenotype was initially developed in 2001 to capture the clinical and biological syndrome of frailty often observed in older adults living in the community. Since that time, the Johns Hopkins Frailty Phenotype has been extensively utilized to diagnose frailty in older adults and to study the specific biology that underlies the syndrome of frailty. The instrument was designed to maintain syndrome construct validity while maximizing feasibility and usability in both research and clinical settings. It has become one of the most commonly utilized and cited instruments available to researchers and clinicians for diagnosing frailty.
The phenotype of frailty can be identified or diagnosed here using 5 measured criteria: unintentional weight loss, exhaustion, low energy expenditure, low grip strength, and slowed waking speed (1)(2). Once data on these measurements are entered into this calculator, a single score will be generated. Scores of 3, 4 and 5 are consistent with frailty, scores of 1 and 2 are consistent with pre-frailty status, and a score of 0 is consistent with a robust or resilient status. We encourage the use of this instrument as implemented within this calculator to facilitate the development of additional biological knowledge about the frailty syndrome, and to encourage the development of specific interventions that will reduce the risk for adverse health outcomes often observed in frail and pre-frail older adults.
