Is degree of chronic illness management in heart transplant centers associated with better patient survival? Findings from the intercontinental BRIGHT study.

PURPOSE: To explore the association between the degree of Chronic illness management and survival rates at 1-, 3-, 5-years post heart transplantation. METHODS: Exploratory secondary analysis of a cross-sectional, international study (Building Research Initiative Group study). Latent profile analysis was performed to classify 36 heart transplant centers according to the degree of chronic illness management. RESULTS: The analysis resulted in 2 classes with 29 centers classified as "low-degree chronic illness management" and 7 centers as "high-degree chronic illness management". After 1-year posttransplantation, the high-degree chronic illness management class had a significantly greater mean survival rate compared to the low-degree chronic illness management class (88.4% vs 84.2%, p = 0.045) and the difference had a medium effect size (η2 = .06). No difference in survival for the other time points was observed. Patients in high-degree chronic illness management centers had 52% lower odds of moderate to severe drinking (95% confidence interval .30-.78, p = 0.003). No significant associations between degree of chronic illness management and the other recommended health behaviors were observed. CONCLUSIONS: The findings from this exploratory study offer preliminary insight into a system-level pathway (chronic illness management) for improving outcomes for heart transplant recipients. The signals observed in our data support further investigation into the effectiveness of chronic illness management-based interventions in heart transplant follow-up care
