"Faith and a sunny day": Association of patient frailty with strain experienced by informal caregivers of older adults with non-muscle-invasive bladder cancer.

Introduction: Few studies have evaluated the potential effects of aging-related conditions like frailty in older adults with cancer on informal caregivers. Our objective was to evaluate the association between the sum total of the aging-related conditions of older adults with non-muscle-invasive bladder cancer (NMIBC) and the strain reported by their informal caregivers.

Materials And Methods: We conducted an explanatory sequential mixed methods cross-sectional survey study that recruited 81 dyads of older adults with NMIBC (age ≥ 65 at diagnosis) and their informal caregivers.
