Although randomized controlled trials have demonstrated benefits of aldosterone antagonists for patients with heart failure and reduced ejection fraction (HFrEF), they excluded patients with serum creatinine >2.5 mg/dl, and their use is contraindicated in those with advanced chronic kidney disease (CKD). In the present analysis, we examined the association of spironolactone use with readmission in hospitalized Medicare beneficiaries with HFrEF and advanced CKD. Of the 1,140 patients with HFrEF (EF <45%) and advanced CKD (estimated glomerular filtration rate [eGFR] <45 ml/min/1.73 m(2)), 207 received discharge prescriptions for spironolactone. Using propensity scores (PSs) for the receipt of discharge prescriptions for spironolactone, we estimated PS-adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for spironolactone-associated outcomes. Patients (mean age 76 years, 49% women, 25% African-American) had mean EF 28%, mean eGFR 31 ml/min/1.73 m(2), and mean potassium 4.5 mEq/L. Spironolactone use had significant PS-adjusted association with higher risk of 30-day (HR 1.41, 95% CI 1.04 to 1.90) and 1-year (HR 1.36, 95% CI 1.13 to 1.63) all-cause readmissions. The risk of 1-year all-cause readmission was higher among 106 patients with eGFR <15 ml/min/1.73 m(2) (HR 4.75, 95% CI 1.84 to 12.28) than among those with eGFR 15 to 45 ml/min/1.73 m(2) (HR 1.34, 95% CI 1.11 to 1.61, p for interaction 0.003). Spironolactone use had no association with HF readmission and all-cause mortality. In conclusion, among hospitalized patients with HFrEF and advanced CKD, spironolactone use was associated with higher all-cause readmission but had no association with all-cause mortality or HF readmission.

Background: Heart failure is the leading cause for 30-day all-cause readmission, the reduction of which is a goal of the Affordable Care Act. There is a growing interest in understanding the impact of evidence-based heart failure therapy on 30-day all-cause readmission. In the current study, we examined the impact of angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEI-ARBs) on 30-day all-cause readmission in heart failure.Methods: Of the 1384 hospitalized Medicare beneficiaries with heart failure and left ventricular ejection fraction <45% discharged alive from 106 Alabama hospitals (1998-2001) without prior ACEI-ARB use and without known contraindications to ACEI-ARB use; 734 received new predischarge prescriptions for these drugs. Using propensity scores for ACEI-ARB initiation, we assembled a matched cohort of 477 pairs of patients balanced on 32 baseline characteristics (mean age 75 years, 46% women, 26% African American).Results: Thirty-day all-cause readmissions occurred in 18% and 24% of matched patients receiving and not receiving ACEI-ARBs, respectively (hazard ratio [HR] 0.74; 95% confidence interval [CI], 0.56-0.97; P = .030). ACEI-ARB use was also associated with lower risk of 30-day all-cause mortality (HR 0.56; 95% CI, 0.33-0.98; P = .041) and of the combined endpoint of 30-day all-cause readmission or 30-day all-cause mortality (HR 0.73; 95% CI, 0.56-0.94; P = .017). All associations remained significant at 1 year post discharge.Conclusions: Among hospitalized patients with heart failure and reduced ejection fraction, the use of ACEI-ARBs was associated with a significantly lower risk of 30-day all-cause readmission and 30-day all-cause mortality; both beneficial associations persisted during long-term follow-up.

Background: The use of opioids is associated with poor outcomes. Less is known about this association in patients with heart failure (HF) and whether it varies by the receipt of hospice care., Methods: Of the 7467 patients hospitalized for HF without previous opioid use, 124 received discharge opioids. We matched 123 of these patients with 123 not receiving opioids based on their propensity scores for opioid use, thus assembling a matched cohort of 246 patients balanced on 30 baseline characteristics (mean age, 76 years, 60% women, and 11% African American). We repeated the process in hospice (n = 155; 20 received opioids) and nonhospice (n = 7298; 104 received opioids) subgroups, thus assembling 2 matched cohorts of 22 and 208 patients, respectively. Hazard ratios (HRs) and 95% confidence intervals (CIs) associated with opioid use were estimated from matched cohorts., Results: During 8.6 (median, 1.4) years of follow-up, all-cause mortality occurred in 80% and 68% of matched patients in the opioid and nonopioid groups, respectively (HR, 1.49; 95% CI, 1.11-1.99; P = 0.008). There was evidence of heterogeneity in this association between hospice and nonhospice patients (P for interaction, 0.027). Among matched hospice and nonhospice patients, HRs (95% CIs) for mortality were 6.37 (2.06-19.69; P = 0.001) and 1.42 (1.03-1.96; P = 0.035), respectively. HRs (95% CIs) for 30-day and 1-year mortality were 1.98 (1.06-3.70; P = 0.033) and 1.72 (1.18-2.49; P = 0.004), respectively. HRs (95% CIs) for all-cause, HF, and non-HF readmissions were 1.31 (0.97-1.76; P = 0.079), 1.03 (0.71-1.49; P = 0.866), and 1.75 (1.05-2.91; P = 0.031), respectively. Readmission associations were similar among matched nonhospice patients. There was no readmission among matched hospice patients receiving opioids., Conclusions: In older patients with HF, opioid use is associated with a higher risk of mortality, which is greater in the hospice subgroup, and a higher risk of non-HF readmission in the nonhospice subgroup.

Background: Angiotensin-converting enzyme inhibitors or angiotensin receptor blockers (ACEIs-ARBs) improve outcomes in heart failure (HF). Less is known about this association in nursing home (NH) residents., Methods: Of the 8024 hospitalized HF patients, 542 were NH residents, of whom 250 received ACEIs-ARBs. We assembled a propensity score-matched cohort of 157 pairs of NH residents receiving and not receiving ACEIs-ARBs balanced on 29 baseline characteristics (mean age, 83 years, 74% women, 17% African American), in which we estimated hazard ratios (HRs) and 95% confidence intervals (CIs) for outcomes associated with ACEI-ARB use. We then checked for interaction in a matched cohort of 5130 patients (378 were NH residents) assembled from the 8024 patients., Results: Among 314 matched NH residents, HRs (95% CIs) for 30-day all-cause readmission, HF readmission, and all-cause mortality were 0.78 (0.47-1.28), 0.68 (0.29-1.60), and 1.26 (0.70-2.27), respectively. Respective HRs (95% CIs) at 1 year were 0.76 (0.56-1.02), 0.68 (0.42-1.09), and 1.04 (0.78-1.38). Among 5130 matched patients, ACEI-ARB use was associated with a significantly lower risk of all outcomes at both times, with no significant interactions, except for 1-year mortality, which was only significant in the non-NH subgroup (P for interaction, 0.026)., Conclusions: We found no evidence that the use of ACEIs or ARBs is associated with improved outcomes in patients with HF in the NH setting. However, we also found no evidence that this association is different in NH residents with HF versus non-NH patients with HF. Future larger studies are needed to demonstrate effectiveness of these drugs in the NH setting.

Inotropes improve symptoms in advanced heart failure (HF) but were associated with higher mortality in clinical trials. Recurrent hospitalizations, arrhythmias, and infections contribute to morbidity and mortality, but the risks of these complications with modern HF therapies are not well known. We collected arrhythmia, infection, and hospitalization data on 197 patients discharged from our institution from January 2007 to March 2013 on intravenous inotropes. Patients were followed until they died, received a transplant or left ventricular assist device, were weaned off inotropes, or remained on inotropes at the end of the study. All patients had stage D HF. At baseline, 30% had a history of ventricular tachycardia, 7.1% had a history of cardiac arrest, and 39% had a history of atrial fibrillation. During follow-up, 33 patients (17%) had one or more implantable cardioverter-defibrillator shocks. Of patients who had shocks, 27 patients (82%) had appropriate shocks for ventricular tachycardia/ventricular fibrillation, 3 patients (9%) had inappropriate shocks, and 3 patients (9%) had both appropriate and inappropriate shocks. The risk of implantable cardioverter-defibrillator shock was not related to dose of inotrope (p = 0.605). Fifty-seven patients (29%) had one or more infections during follow-up. Bacteremia was the most common type of infection. Implanted electrophysiology devices did not confer an increased risk of infection. One hundred twelve patients (57%) had one or more hospitalizations during follow-up. Common causes of hospitalizations were worsening HF symptoms (41%), infections (20%), and arrhythmias (12%). In conclusion, arrhythmias, infections, and rehospitalizations are important complications of inotropic therapy., (Copyright © 2016 Elsevier Inc. All rights reserved.)

Background: Heart failure (HF) is the leading cause for hospital readmission. Hospice care may help palliate HF symptoms but its association with 30-day all-cause readmission remains unknown., Methods and Results: Of the 8032 Medicare beneficiaries hospitalized for HF in 106 Alabama hospitals (1998-2001), 182 (2%) received discharge hospice referrals. Of the 7850 patients not receiving hospice referrals, 1608 (20%) died within 6 months post discharge (the hospice-eligible group). Propensity scores for hospice referral were estimated for each of the 1790 (182+1608) patients and were used to match 179 hospice-referral patients with 179 hospice-eligible patients who were balanced on 28 baseline characteristics (mean age, 79 years; 58% women; 18% non-white). Overall, 22% (1742/8032) died in 6 months, of whom 8% (134/1742) received hospice referrals. Among the 358 matched patients, 30-day all-cause readmission occurred in 5% and 41% of hospice-referral and hospice-eligible patients, respectively (hazard ratio associated with hospice referral, 0.12; 95% confidence interval, 0.06-0.24). Hazard ratios (95% confidence intervals) for 30-day all-cause readmission associated with hospice referral among the 126 patients who died and 232 patients who survived 30-day post discharge were 0.03 (0.04-0.21) and 0.17 (0.08-0.36), respectively. Although 30-day mortality was higher in the hospice referral group (43% versus 27%), it was similar at 90 days (64% versus 67% among hospice-eligible patients)., Conclusions: A discharge hospice referral was associated with lower 30-day all-cause readmission among hospitalized patients with HF. However, most patients with HF who died within 6 months of hospital discharge did not receive a discharge hospice referral., (© 2015 American Heart Association, Inc.)
