Heart failure & cardiomyopathiesMeta-analysis
Global Comparison of Readmission Rates for Patients With Heart Failure
- Systematic review and meta-analysis of observational studies
- random-effects model
- meta-regression
Authors' conclusion
Globally, hospitalized HF patients exhibit high rates of readmission and mortality, and the variability in readmission rates was not explained by health care expenditure, risk of mortality, or comorbidities.
Study context
- Population
- Hospitalized adults with heart failure (HF) at risk for readmission or mortality; observational reports published January 2010–March 2021
- Participants
- 1.5 million adults
- Outcome
- All-cause readmission and mortality rates
- Follow-up
- 30 days and 1 year
Pooled result
As reported in the abstract
All-cause readmission and mortality
Readmitted within 30 days (24 papers)
13.2% (95% CI: 10.5%-16.1%)
Readmitted within 1 year (23 papers)
35.7% (95% CI: 27.1%-44.9%)
Died within 30 days (33 papers)
7.6% (95% CI: 6.1%-9.3%)
Died within 1 year (45 papers)
23.3% (95% CI: 20.8%-25.9%)
Further pooled results
Variation across countries
- Substantial variation in risk across countries unexplained by gross domestic product, proportion spent on health care, and Gini coefficient
