BACKGROUND
Indwelling urethral catheters (IUC) are routinely inserted for the purpose of monitoring urine output in patients with acute heart failure (AHF). The benefit of IUC in patients capable of complying with urine collection protocols is unclear, and IUC carry multiple risks. This study describes the impact of IUC on AHF treatment.Methods and Results:A total of 540 records were retrospectively analyzed. After exclusion criteria were applied, 316 patients were propensity matched to establish groups of 100 AHF patients who either did (IUC(+)) or did not receive an IUC (IUC(-)) upon admission. Hospital length of stay (9 vs. 7 days), in-hospital urinary complications (24 vs. 5%), and 1-year urinary tract infection rate (17 vs. 6%; HR, 3.145; 95% CI: 1.240-7.978) were significantly higher in the IUC(+) group (P<0.05 for all). There were no differences in 30-day rehospitalization (6 vs. 6%; HR, 0.981; 95% CI: 0.318-3.058; P=0.986) or major adverse cardiac/cerebrovascular events at 1 year (37 vs. 32%, HR, 1.070; 95% CI: 0.636-1.799; P=0.798).
CONCLUSIONS
Based on this retrospective analysis, the routine use of IUC may increase length of stay and UTI complications in AHF patients without reducing the risk for major cardiovascular and cerebrovascular events or 30-day rehospitalization rate.

BACKGROUND
Different outcomes among patients hospitalized for bleeding after starting anticoagulation could influence choice of anticoagulant. We compared length of hospitalization, proportion of Intensive Care Unit (ICU) admissions, ICU length of stay, and 30- and 90-day mortality for adults with atrial fibrillation hospitalized for bleeding after starting warfarin, dabigatran, or rivaroxaban.
METHODS
An US commercial database of 38 million members from 1 November 2010 to 31 March 2014 was used to examine adults with atrial fibrillation hospitalized for bleeding after starting warfarin (2,446), dabigatran (442), or rivaroxaban (256). Outcomes included difference in mean total length of hospitalization, proportion of ICU admissions, mean length of ICU stay, and all-cause 30- and 90-day mortality.
RESULTS
Warfarin users were older and had more comorbidities. Multivariable regression modeling with propensity score weighting showed warfarin users were hospitalized 2.0 days longer (95% CI 1.8-2.3; p < 0.001) than dabigatran users and 2.6 days longer (95% CI 2.4-2.9; p < 0.001) than rivaroxaban users. Dabigatran users were hospitalized 0.6 days longer (95% CI 0.2-1.0; p = 0.001) than rivaroxaban users. There were no differences in the proportion of ICU admissions. Among ICU admissions, warfarin users stayed 3.0 days (95% CI 1.9-3.9; p < 0.001) longer than dabigatran users and 2.4 days longer (95% CI 0.9-3.7; p = 0.003) than rivaroxaban users. There was no difference in ICU stay between dabigatran and rivaroxaban users. There were no differences in 30- and 90-day all-cause mortality.
CONCLUSIONS
Rivaroxaban and dabigatran were associated with shorter hospitalizations; however, there were no differences in 30- and 90-day mortality. These findings suggest bleeding associated with the newer agents is not more dangerous than bleeding associated with warfarin.
