Heart failure & cardiomyopathies
Factors Impacting Physician Prognostic Accuracy in Heart Failure Patients With Reduced Left Ventricular Ejection Fraction
Authors' conclusion
Discrepant physician and model predictions were more frequent in cases with perceived increased risk. Model predictions outperform physicians even when they are confident in their predictions.
Study context
- Population

Main finding
As reported in the abstract
Discrepant physician vs model predictions
Odds ratio (95% CI)
Female HF cardiologistsmale patients; 26% more likely discrepant
0.74(0.58–0.94)
HF cardiologists, Black patients33% more likely discrepant
0.67(0.45–0.99)
- Estimates discrepant between model and physician, mainly physician risk overestimation
- One-half
- Discrepancy in low-risk patients
- 38%
- Discrepancy in high-risk patients
- ∼75%
Observational data: associations, not effects.

- 10% (95% CI: 8%-12%)
Calibration, high-confidence estimates only
- Inferior calibration to the model, risk overestimation across risk groups
