Abstract
BackgroundAccuracy of New York Heart Association Functional Classification (NYHA-FC) I-IV assessment is critical to promoting guideline directed care. ObjectiveExamine providers’ accuracy when diagnosing NYHA-FC I-IV in patients with heart failure (HF). MethodsA web-based survey using validated vignettes was conducted with 244 physicians, nurse practitioners (NP), clinical nurse specialists (CNS) and physician assistants (PA) who provide care to patients with HF. ResultsProviders comprised of 65% NPs, 19% physicians, 14% CNSs, 2% PAs with an average of 15 years working with HF patients. Accuracy ranged from 36.9% for Class IV to 78.7% for Class I. Increased HF patient volume seen (p=0.024), physician vs. NP/PA/CNS (p=0.021), and typically assigned a HF stage (p<0.001) were associated with increased total correct score accuracy in multivariable modeling. ConclusionIt is critical that NYHA-FC is accurately assigned to promote optimal outcomes. Research in the future should focus on improving accuracy in assigning NYHA-FC.
