Informal caregivers need information, skills and emotional support to address physical, spiritual, and emotional needs associated with chronic illnesses including late stage cancer. Unfortunately, current conditions force clinicians to reduce their interaction time with patients and informal caregivers. Complimentary methods must be developed to provide needed information and support to caregivers. The proposed research will measure and explain the impact of two computer-based support systems that meet caregiver needs and facilitate information exchange with clinicians. The system, CHESS (Comprehensive Health Enhancement Support System) is a non-commercial computer system that provides patients with disease specific information, emotional support and skill building tools. In the expanded form to be tested in this study, CHESS with Caregiver Support (CGCHESS) will also provide the caregiver with more information, support and skills training related to palliative care. CGCHESS will be further enhanced to communicate essential patient and caregiver information to clinicians prior to a scheduled clinic visit and when patient symptoms exceed a threshold.
