Webtool to Enhance the Accuracy of Diagnostic Algorithms for Heart Failure with Preserved Ejection Fraction (HFpEF): A Prospective Cross-Over Study
Authors' conclusion
Manual calculation of HFpEF diagnostic algorithms is often inaccurate. Using an automated webtool to calculate HFpEF algorithms significantly improved correct scoring.
Study context
- Population
- Cardiologists with varying clinical experience scoring eight online clinical cases
- Participants
- 55 study completers
- Exposure
- Manual vs automatic scoring of HFA-PEFF and H2 FPEF algorithms
- Outcome
- Scoring accuracy (percentage of correct scores)
Methodological detailstriple cross-over design
- Triple cross-over design
