OBJECTIVES
To determine the relationship between 6-min walk test distance (6MWD) and 30-day readmission in hospitalized heart failure (HF) patients.
BACKGROUND
6MWD is known to predict hospitalizations in outpatients with HF, but its ability to predict recidivism in hospitalized HF patients is relatively unknown.
METHODS
Seventy-one hospitalized HF patients with NYHA Class II/III (mean age 52.6 ± 12.3 years, 42.3% female, 73.2% African American) performed 6MWD prior to discharge. Logistic regression was used to determine relationships between 6MWD and 30-day readmission.
RESULTS
30-day readmission occurred in 14 (19.7%) patients. Average 6MWD was 756.4 ± 403.2 feet. Higher 6MWD significantly decreased risk of 30-day readmission, even after adjusting for sociodemographic and clinical characteristics (OR = .84, 95% CI [.71, .99]). For each additional 100 feet walked, odds of a 30-day readmission decreased by 16%.
CONCLUSIONS
6MWD predicted 30-day readmission in this study, warranting further investigation to understand how the 6MWD may predict readmissions and guide treatment in hospitalized HF patients.
目的
确定住院心力衰竭（HF）患者的6分钟步行试验距离（6MWD）与30天再入院之间的关系。
背景
已知6MWD可预测HF门诊患者的住院情况，但其预测住院HF患者再入院的能力相对未知。
方法
71例NYHA II/III级住院HF患者（平均年龄52.6±12.3岁，42.3%为女性，73.2%为非裔美国人）在出院前进行了6MWD测试。采用逻辑回归确定6MWD与30天再入院之间的关系。
结果
14例（19.7%）患者发生了30天再入院。平均6MWD为756.4±403.2英尺。即使在调整了社会人口统计学和临床特征后，较高的6MWD也显著降低了30天再入院的风险（OR = 0.84，95%CI[0.71，0.99]）。每多走100英尺，30天再入院的几率就降低16%。
结论
在本研究中，6MWD可预测30天再入院情况，有必要进一步研究以了解6MWD如何预测再入院并指导住院HF患者的治疗。
