B-Type Natriuretic Peptide Predicts 30-Day Readmission for Heart Failure but not Readmission for Other Causes.
B-Type Natriuretic Peptide Predicts 30-Day Readmission for Heart Failure but not Readmission for Other Causes. Journal of the American Heart Association Flint, K. M., Allen, L. A., Pham, M., Heidenreich, P. A. 2014; 3 (3)Abstract
B-type natriuretic peptide (BNP) is a marker for heart failure (HF) severity, but its association with hospital readmission is not well defined.We identified all hospital discharges (n=109 875) with a primary diagnosis of HF in the Veterans Affairs Health Care System from 2006 to 2009. We examined the association between admission (n=53 585), discharge (n=24 326), and change in BNP (n=7187) and 30-day readmission for HF or other causes. Thirty-day HF readmission was associated with elevated admission BNP, elevated discharge BNP, and smaller percent change in BNP from admission to discharge. Patients with a discharge BNP = 1000 ng/L had an unadjusted 30-day HF readmission rate over 3 times as high as patients whose discharge BNP was = 200 ng/L (15% vs. 4.1%). BNP improved discrimination and risk classification for 30-day HF readmission when added to a base clinical model, with discharge BNP having the greatest effect (C-statistic, 0.639 to 0.664 [P<0.0001]; net reclassification improvement, 9% [P<0.0001]). In contrast, 30-day readmission for non-HF causes was not associated with BNP levels during index HF hospitalization.In this study of over 50 000 veterans hospitalized with a primary diagnosis of HF, BNP levels measured during hospitalization were associated with 30-day HF readmission, but not readmissions for other causes. These data may help guide future study aimed at identifying the optimal timing for hospital discharge and help allocate high-intensity, HF-specific transitional care interventions to the patients most likely to benefit.
