Heart failure & cardiomyopathies
Impact of Sleep Apnoea on 30 day Hospital Readmission Rate and Cost in Heart Failure with Reduced Ejection Fraction
Authors' conclusion
In patients with obstructive sleep apnoea admitted with heart failure with reduced ejection fraction, we found a substantial all-cause readmission rate of 23.4% with heart failure readmission constituting about 48.9% of readmissions. Readmissions were associated with higher mortality and resource use.

Readmissions due to decompensated HF
- Proportion of readmissions due to decompensated HF
- 48.9%
Aggregate charges and costs of all 30-day readmissions
- Total hospital charges
- $195 million
- Total hospital costs
- $46.9 million
Predictors of readmission
- Higher readmission: Medicaid insurance, higher Charlson co-morbidity Index, longer length of stay
- Lower readmission: prior PCI, private insurance
