Key result
A 1 percentage point increase in regional ICD/CRT-D utilization among hospitalized heart failure patients was associated with increased survival at 1 year (0.12%; P=0.009) and 2 years (0.26%; P<0.001).
Why the study?
Does higher regional utilization of ICD/CRT-D improve survival in Medicare beneficiaries hospitalized for heart failure?
Cohort (n=883,002)
Yes
Does higher regional utilization of ICD/CRT-D improve survival in Medicare beneficiaries hospitalized for heart failure?
Effect estimate: 0.12% increase per 1 percentage point increase in utilization (95% CI 0.03-0.21)
p-value: p=0.009
Greater regional increases in ICD/CRT-D utilization are associated with improved 1- and 2-year survival among older patients hospitalized for heart failure.

Does not support changing device utilization practices; leaves open whether higher regional rates causally improve heart failure survival.
Epstein et al. (2011) conducted a cohort in Heart failure (n=883,002). ICD/CRT-D utilization vs. Lower ICD/CRT-D utilization was evaluated on 1-year heart failure survival (0.12% increase per 1 percentage point increase in utilization, 95% CI 0.03-0.21, p=0.009). A 1 percentage point increase in regional ICD/CRT-D utilization among hospitalized heart failure patients was associated with increased survival at 1 year (0.12%; P=0.009) and 2 years (0.26%; P<0.001).
