“…Outcomes were followed up to 24 months after baseline. Most studies applied a dyadic approach involving both the patient and caregiver in the intervention [25, 26, 55, 58, 101, 110, 111, 126, 129, 130], while others focused solely on the caregiver [50, 62, 89, 100, 110]. Five interventions [25, 26, 50, 100, 130] involved individual nurse-led face-to-face psychoeducational sessions sometimes in combination with other approaches to follow-up such as home visits [25, 100], telemonitoring [50] and telephone calls [100, 130].…”
