To compare the effects of Comprehensive Health Enhancement Support System (CHESS) access intervention versus provision of internet with recommended websites for lung care cancer care on informal caregivers’ burden, disruptiveness, and mood
Patients and their caregivers were provided with laptops with internet that allowed access to CHESS. CHESS is a home-based e-health system that helps users to appraise the controllability of cancer-related stressors and improves their cognitive, behavioral, and supportive coping skills by providing them with a variety of information, communication, and coaching services appropriate for cancer caregivers based on their need and preference. CHESS allows sharing critical information with clinicians via Clinician Report, where caregivers are able to communicate their needs, ask questions, and rate patients’ symptoms on a scale of 0–10. A score of 7 or more triggers an email alert to the patient’s treating clinician so he or she is aware of the patient’s and caregiver’s situation on the next patient visit. Patients randomly were assigned to internet use only or CHESS plus internet use. Internet users were provided with internet access and a list of high-quality websites for information.
Average use of CHESS among the intervention group was 14.6 logins, averaging browsing 293 pages and spending 177 minutes on the system (almost 50 minutes monthly). Statistically significant improvement was seen in the intervention group over the control group at six months follow-up in burden (p = .02) and negative mood (p = .006), but not in disruptiveness. These effects persisted even when patient symptom distress (on the ESAS) and other covariates were controlled. Analyses also show that these significant differences existed only at six-month follow-up, not at any other times.
Targeted electronic systems that are designed comprehensively to help caregivers can improve their experience of caregiving by minimizing their perceived burden and improving their mood.
Targeted e-health systems are more likely to be beneficial to caregivers of patients with cancer when they are self-directed and have a comprehensive approach to caregivers’ needs (e.g., information, communication, coaching, interaction with healthcare providers). The benefits of e-health vary among cancer caregivers and depend on how they use the tools offered by such systems. Which feature or combination of features would be most helpful to this group of caregivers remains to be determined.
