RESULTS: The most studied interventions included case management (CM-specialist nurse driven, education pre/post discharge, specialist nurse home visits, scheduled telephone calls for symptom management, when to seek help), multidisciplinary Intervention ( MI-coordinated interventions and communications; specialist nurse driven, patient-caregiver education regarding disease, medication and diet, nurse clinic visits, regular telephone calls, individualized follow-up plan, access to physician, nurse, dietician, pharmacist, social worker), remote monitoring programs consisting of structured telephone strategy (STS-monitoring collected data via human-human or human-machine interactive response system) or tele-monitoring (TM-physiologic data transmission of EKG, blood pressure, weight, respiratory rate digitally). Clinic visits did not have a significant effect on CHF readmission or mortality. CM showed decreased all-cause mortality (ACM) at 12 months, all-cause readmission (ACR) at 12 months and CHF readmission at 6 and 12 months. MI resulted in decreased ACR and CHF readmission. There was some discrepancy on effectiveness of TM programs alone in individual studies, however large meta-analysis suggests TM provided a reduction in ACM and risk of CHF hospitalization. STS had similar results to TM including decreased risk of CHF hospitalization, without an effect on mortality.
