- W2892220851 abstract "Introduction With a 30-day all cause readmission rate around 23%, individuals with heart failure (HF) are a medically high risk and costly patient population. Though predictive models have been developed for readmission based on descriptive variables, many of these tools are cumbersome and limited in prognosticative capacity. A few studies have examined the role of the six-minute walk test (6MWT) and found good predictive ability for both 30-day and 1-3-year readmission rates. The goal of this study was to further elucidate the prognostic ability of the 6MWT in stage C/D HF patients with NYHA class IIIb-VI symptoms. Methods We prospectively enrolled 97 patients who from our step-down units with a primary diagnosis of heart failure between October 2016 and March 2017. Every patient who was enrolled had a standardized 6MWT prior to discharge. Multivariate logistic regression analysis was constructed to determine relationships between 6MW distance and 30-day survival free of readmission. Results Baseline characteristics were compared between the 6-minute walk test distance groups using Wilcoxon rank-sum tests for continuous variables and Fisher's exact tests for categorical variables, and no significant differences were found between the patients. The 135-meter cut-point was selected as the threshold which maximizes the sum of sensitivity and specificity of a logistic regression model for 30-day readmission with 6-minute walk test distance as a continuous predictor. Approximately 25.7% of the patients walked less than 135 meters. Out of these about 32% were admitted within 30 days [p= .026]. Among the patients who walked > 135 meters, 11.1% were admitted within 30 days [p= 0.026]. Furthermore, patients who walked Conclusions 6MWT distance less than 135m was associated with not only increased risk of 30 day readmission but also correlated with increased frequency of admissions in patients admitted with stage C/D heart failure." @default.
