    ContextIn clinical trials, N-terminal pro-brain natriuretic peptide (NT-proBNP) testing has been shown to be valuable for diagnosis and triage of patients with acute decompensated heart failure. It is not yet clear what benefits might be expected from the initiation of NT-proBNP testing in an everyday clinical setting.ObjectiveTo determine the effects of NT-proBNP testing on hospital length of stay as well as on 60-day morbidity and mortality in patients with acute decompensated heart failure before and after the test was implemented in the clinical laboratory.DesignWe measured hospital length of stay and 60-day morbidity and mortality rates among patients with acute decompensated heart failure admitted before and after initiation of NT-proBNP testing in our hospital. Differences in demographics between preimplementation and postimplementation groups were compared with the chi2 test for categorical variables and the Wilcoxon rank sum test for continuous variables. Comparison between the hospital length of stay for each group was evaluated using the Mann-Whitney U test. Differences in rates of rehospitalization or death at 60 days following presentation were assessed using chi2 cross-tabulation.ResultsPatients in the postimplementation group had similar clinical features as those in the preimplementation group. The hospital length of stay for patients in the postimplementation study group decreased both with respect to mean (1.86-day reduction) and median (1.3-day reduction) hospital stay (both, P = .03). Additionally, significantly lower rates of death (6.6% absolute risk reduction, P = .01), rehospitalization (12.1% absolute risk reduction, P = .005), and the composite of the 2 rates (18.7% absolute risk reduction, P = .008) were found following initiation of NT-proBNP testing.ConclusionsImplementation of NT-proBNP testing may result in significant reductions in hospital length of stay as well as improvements in rates of morbidity and mortality in patients with acute decompensated heart failure.
