Public reporting of aortic valve surgery outcomes reduced valve replacement rates for infective endocarditis (IE) patients, including those with injection drug use (IDU-IE). This initiative also lowered in-hospital mortality for all IE cases.
Area of Science:
- Cardiology
- Public Health
- Health Services Research
Background:
- Injection drug use-associated infective endocarditis (IDU-IE) is a growing concern requiring valve surgery.
- The impact of public outcomes reporting on aortic valve surgery for endocarditis remains unclear.
Purpose of the Study:
- To evaluate the effect of public reporting on aortic valve surgery rates and in-hospital mortality for infective endocarditis (IE).
- To determine if these effects differ between patients with and without a history of injection drug use.
Main Methods:
- An interrupted time series analysis using the National Inpatient Sample (2010-2015).
- Inclusion of patients aged 18-65 diagnosed with endocarditis, with IDU-IE identified via ICD-9 codes.
- Segmented logistic regression to analyze changes in valve replacement and mortality rates post-public reporting implementation in January 2013.
Main Results:
- Following public reporting, the odds of valve replacement decreased by 4.0% quarterly for all IE patients, irrespective of IDU status.
- In-hospital mortality rates decreased by 2.0% quarterly for both IDU-IE and non-IDU-IE cases.
- No significant difference in the change of valve replacement rates was observed based on IDU status.
Conclusions:
- Public reporting initiation correlated with decreased valve surgery for IE patients and reduced in-hospital mortality.
- Patients with IE may experience reduced surgical access due to public reporting.
- Further research is needed to investigate post-discharge mortality to understand the overall impact of reduced surgery rates.
