Cathy Maxwell PhD, RN, FAAN

Cathy Maxwell

Dr. Maxwell's research is directed at understanding outcome trajectories of older adults related to functional decline and frailty. Dr. Maxwell has examined outcomes in relationship to older adults' frailty status and reported one-year outcomes of older adults hospitalized for an injury (falls), including functional decline, readmissions to acute care and mortality. Most recently, Dr. Maxwell developed an educational tool for older adults to facility their understanding of the concept of frailty and to encourage proactive management of their personal trajectories of aging. She is interested in interventions with a nursing focus that empower older adults to engage in behaviors that enhance well-being and improve quality of life.
