Although the interventions we reviewed used different approaches and targeted a variety of outcomes, they share some common features. Each provided training and support to family caregivers, each used a standard program that could be individualized to meet the specific and unique needs of participants, and each provided a means to identify and solve implementation problems. Clearly, future research on interventions will benefit from lessons learned in these investigations. As researchers refine these approaches and develop new ones, it is important to continue to evaluate their efficacy and safety, identify more powerful and efficient approaches, train caregivers to use them appropriately, increase their availability to those who will benefit from them, and continue to keep QOL as a central focus of care.
