The family caregiver of the older cancer patient.

Cancer care is becoming increasingly complex. The health care practices of the present day make it imperative that the family provide assistance in the day-to-day management of a patient's symptoms and in the implementation of home care. This increased responsibility for the family caregiver can come at great cost to the overall functioning of the family, because of role changes, changes in the family structure, and financial stressors, among others. Caregivers can experience adverse effects on their mental and physical health that can remain long after the caregiving role has ended. Although much of the research has focused on the negative elements of caregiving, it must be remembered that there are positive aspects to caregiving, which are now receiving attention in the research literature. Although other factors affect caregiving, the model of factors important in the caregiving experience presented in this article may provide the impetus for studying the relationships among these different factors. Results of these studies will allow the development of specific interventions to help caregivers be more effective in their caregiving role and, at the same time, address the overall impact of caregiving on the family.
