The purpose of the current study was to examine the role and activities of family caregivers for older relatives during hospitalization. The Family Care Actions Index was completed by 293 family caregivers of hospitalized older adults. Results indicated that the scope of caregiving activities extended beyond providing care to the patient and included working together with the health care team. Activities requiring interaction with providers, such as care coordination, planning, evaluation, and oversight, were frequently performed by family caregivers. Family caregivers are assuming a greater role during the hospital stay of older relatives. Partnering with family caregivers provides hospital staff an opportunity to improve care, outcomes, and satisfaction. [Journal of Gerontological Nursing, 46(3), 45–50.]
