Heart failure & cardiomyopathiesCohort study

Hospital Heart Failure Medical Therapy Score and Associated Clinical Outcomes and Costs

JAMA CardiolPublished

  • Retrospective cohort study
  • registry-based
  • 360 hospitals
  • Data analyzed July 2022 to April 2023
  • Costs from the CMS perspective

Authors' conclusion

Results of this cohort study reveal that hospital variability in GDMT score, clinical outcomes, and costs was significant. Higher GDMT score at discharge was associated with lower mortality, lower mortality or hospitalization, more home time, and lower cost.

Study context

Population
Patients hospitalized for HF with Reduced Ejection Fraction (HFrEF) in the Get With the Guidelines-Heart Failure Registry, 2015–2019
Participants
41,161 patients · 360 hospitals
Exposure
Hospital guideline-directed medical therapy (GDMT) score at discharge vs clinical outcomes and costs
Outcome
Hospital variability in GDMT score (weighted index 0–1) at discharge (AMOR); parallel analyses of mortality, HF rehospitalization, mortality or HF rehospitalization, home time and costs; associations with hospital GDMT score (Spearman)
Follow-up
90 days

Main finding

As reported in the abstract

Association of higher hospital GDMT score with outcomes and costs
Mortality: Spearman ρ −0.22 (95% CI −0.32 to −0.12)
P < .001
Mortality or heart failure (HF) rehospitalization: Spearman ρ −0.17 (95% CI −0.26 to −0.06)
P = .002
Home time: Spearman ρ 0.14 (95% CI 0.03-0.24)
P = .01
Cost: Spearman ρ −0.11 (95% CI −0.21 to 0)
P = .047
HF rehospitalization (not associated): Spearman ρ −0.10 (95% CI −0.20 to 0)
P = .06

Observational data: associations, not effects.
