Providers' accuracy in decision-making with assessing NYHA functional class of patients with heart failure after use...

Area of Science:

• Cardiology
• Clinical Practice Guidelines
• Healthcare Quality Improvement

Background:

• Accurate New York Heart Association Functional Classification (NYHA-FC) is critical for effective guideline-directed heart failure (HF) care.
• Variability in NYHA-FC assignment can impact patient management and outcomes.

Purpose of the Study:

• To evaluate the validity, reliability, and accuracy of the NYHA-FC Guide for assigning functional classification.
• To compare the performance of heart failure (HF) specialists and primary care (PC) providers in using the NYHA-FC Guide.

Main Methods:

• A cross-sectional, quasi-experimental design with validated vignettes was employed.
• Seventy-five healthcare providers (HF specialists and PC providers) used the NYHA-FC Guide to assign classifications.
• Known-group validity and interrater reliability analyses were conducted.

Main Results:

• HF providers achieved significantly higher accuracy scores (M=6.0) compared to PC providers (M=5.4; p=0.020).
• A majority of HF providers (62%) and PC providers (80%) reported the Guide aided in classifying heart failure.

Conclusions:

• The NYHA-FC Guide demonstrates potential for enhancing the accuracy of functional classification assignment.
• Further research comparing the Guide's accuracy to the six-minute walk test is recommended.
