A standardized, evidenced-based method to assess frailty across clinical and research settings.

The Johns Hopkins Frailty Assessment Calculator


Physical frailty in older adults is a clinically recognizable state of increased vulnerability to adverse health outcomes such as disability, falls, institutionalization, and death. It is often defined as a medical syndrome that results from age-associated declines across multiple physiologic systems. Clinicians and researchers need a standardized method to consistently and accurately identify those patients who are most frail to better manage their care. Hundreds of studies have shown frailty—a clinically recognizable state of increased vulnerability to adverse health outcomes such as disability, falls, institutionalization, and death—to be useful in assessing patient risk.


The online Johns Hopkins Frailty Assessment Calculator allows a clinician or researcher to enter five standardized measurements. The output is a single score that is automatically generated, providing a classification of either frail (score 3-5), pre-frail (score 1 or 2) or robust (score 0). The Hopkins Frailty Assessment Calculator is one of the most commonly utilized and cited tools available for researchers and clinicians. Using this tool, frailty is defined using measures of five phenotypic criteria: unintentional weight loss, exhaustion, low energy expenditure, low grip strength, and/or slowed walking speed.



The calculator is used at Johns Hopkins in both surgical and transplant services to:

  • reduce post-surgical complications
  • reduce pain and suffering
  • improve quality of life

This could save tens of millions of dollars in health care costs annually.


For 130 years, Johns Hopkins Hospital has led the way in both biomedical discovery and health care, establishing the standard by which others follow and build upon. This is one of many faculty-developed programs, protocols and services provided by Johns Hopkins HealthCare Solutions to improve health outcomes and reduce the cost of care.
