Why the study?

Regional disparities in cardiovascular disease outcomes have been suggested across the United States, but whether significant regional differences exist in care quality and short-term outcomes among hospitalized heart failure patients remained to be examined.

Does US geographic region impact quality of care and short-term outcomes in patients hospitalized for heart failure?

Population

423 333 patients hospitalized for HF in 488 hospitals across 4 US Census Bureau regions

Comparison

Comparison across 4 US Census Bureau regions

Overview

Persistent regional HF care and outcome disparities warrant attention; leaves open whether targeted interventions can reduce gaps.

Structured PICO

Does US geographic region impact quality of care and short-term outcomes in patients hospitalized for heart failure?

P
Population
423,333 patients hospitalized for heart failure in 488 hospitals across 4 US Census Bureau regions, enrolled in the GWTG-HF (Get With The Guidelines–Heart Failure) registry from 2010 to 2016.
I
Intervention
Hospitalization in specific US Census Bureau regions (e.g., Midwest)
C
Comparator
Hospitalization in other US Census Bureau regions (e.g., Northeast)
O
Outcome
In-hospital mortality and length of stayhard clinical

Despite similar quality of care across US regions, risk-adjusted in-hospital mortality for heart failure is significantly lower in the Midwest compared to the Northeast.

Limitations

  • Unmeasured differences in patient characteristics
