The CLASS-HF Guide demonstrated moderate interrater reliability (κ = 0.462) and significant validity through an inverse correlation with 6-minute walk test distance (rs = -0.469, P<0.001).
Observational
Does the CLASS-HF Guide provide reliable and valid assignment of NYHA functional class in heart failure patients?
The CLASS-HF Guide demonstrates moderate interrater reliability and concurrent validity against the 6-minute walk test for assigning NYHA functional class.
Effect estimate: rs = -0.469
p-value: p=<0.001
Background: The New York Heart Association Functional Classification (NYHA-FC) is used in clinical practice to assess functional capacity. Objective: This study examined the reliability and validity of the Consistently Assess Signs and Symptoms of Heart Failure (CLASS-HF) Guide in the assignment of NYHA-FC. Methods: Providers assigned NYHA-FC using the CLASS-HF Guide and patients completed a 6-minute walk test. Results: Interrater reliability revealed moderate agreement (κ = 0.462) among heart failure providers. A significant inverse correlation was found between assigned NYHA-FC and 6-minute meters walked ( r s = −0.469, P < .001), with significant mean differences (analysis of variance F (3,99) = 10.72, P < .001) in distance walked. Conclusions: The CLASS-HF Guide showed evidence of reliability and validity.
Prasun et al. (Mon,) conducted a observational in Heart failure. CLASS-HF Guide was evaluated on Interrater reliability and correlation with 6-minute walk test distance (rs = -0.469, p=<0.001). The CLASS-HF Guide demonstrated moderate interrater reliability (κ = 0.462) and significant validity through an inverse correlation with 6-minute walk test distance (rs = -0.469, P<0.001).
