Overview

This clinical trial assesses whether resource identification for primary caregivers can affect financial stress, quality of life, depression, and the general belief in the ability to cope with daily life. Caregivers of patients receiving cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CS+HIPEC) demonstrate that they endure high depressive symptom burdens and financial distress. Further, they experience symptom trajectories that differ from those of patients. In short, they require differential timing of supportive interventions. This study aims to reduce financial toxicity and distress levels and to increase self-efficacy, satisfaction and engagement with care. Information gathered from this study may help researchers determine whether telehealth interventions for caregivers may increase awareness of recommended resources that could be beneficial during caregivers journey.
