National Rate of Tobacco and Substance Use Disorders Among Hospitalized Heart Failure Patients.

ABSTRACT: BACKGROUND:Several cardiotoxic substances impact heart failure incidence. The burden of comorbid tobacco or substance use disorders among heart failure patients is under-characterized. We describe the burden of tobacco and substance use disorders among hospitalized heart failure patients in the United States. METHODS:We calculated the proportion of primary heart failure hospitalizations in the 2014 National Inpatient Sample with tobacco or substance use disorders accounting for demographic factors. RESULTS:Of 989,080 heart failure hospitalizations, 15.5% (n?=?152,965) had documented tobacco (n?=?119,285, 12.1%) or substance (n?=?61,510, 6.2%) use disorder. Female sex was associated with lower rates of tobacco (odds ratio [OR] 0.72; 95% confidence interval [CI], 0.70-0.74) and substance (OR 0.37; 95% CI, 0.36-0.39) use disorder. Tobacco and substance use disorder rates were highest for hospitalizations <55years of age. Native American race was associated with increased risk of alcohol use disorder (OR 1.67; 95% CI, 1.27-2.20) and black race with alcohol (OR 1.09; 95% CI, 1.02-1.16) or drug (OR 1.63; 95% CI, 1.53-1.74) use disorder. Medicaid insurance or income in the lowest quartile were associated with increased risk of tobacco and substance use disorders. CONCLUSIONS:Tobacco and substance use disorders affect vulnerable heart failure populations, including those of male sex, younger age, lower socioeconomic status, and racial/ethnic minorities. Enhanced screening for tobacco and substance use disorders in hospitalized heart failure patients may reveal opportunities for treatment and secondary prevention.

Project description:Background Although aldosterone antagonists improve outcomes in select individuals with heart failure and reduced ejection fraction, studies in the United States have raised concerns about underuse and overuse. Variations in the prescription of aldosterone antagonist in China are unknown. Methods and Results In the multicenter, hospital-based, retrospective China PEACE (China Patient-Centered Evaluative Assessment of Cardiac Events) study, we identified a nationally representative cohort of admissions for heart failure in a nationally representative sample of Chinese hospitals in 2015. Patients were classified into 1 of 3 groups according to their eligibility for spironolactone-"ideal" (left ventricular ejection fraction <40% and without contraindications), "contraindicated" (a documented contraindication, irrespective of left ventricular ejection fraction), and "uncertain-benefit" (all others). We measured hospital variation of spironolactone prescriptions at discharge in the "ideal" and "contraindicated" group and calculated the median odds ratio (MOR), a measure of institution-level variation for 2 individuals with similar characteristics discharged at 2 randomly selected hospitals. Hospital characteristics associated with spironolactone use were identified using multivariable linear regression model. Among 1222 ideal patients from 97 hospitals, the median rate of spironolactone prescription was 78.6% (interquartile range [IQR], 42.8%-89.6% [range, 0%-100%], MOR, 3.4 [95% CI, 2.7-4.0]) at discharge. Among 900 contraindicated patients from 83 hospitals, the median rate of spironolactone prescription was 30.0% (IQR, 9.1%-50.0% [range, 0%-100%], MOR, 3.1 [95% CI, 2.4-3.9]) at discharge. Hospitals with independent departments of cardiology and located in Eastern China were associated with a 38.0% (95% CI, 18.7-57.3; P<0.001) and a 14.6% (95% CI, 2.3%-26.9%; P=0.020) higher rate of spironolactone use for ideal patients. Conclusions In this national study of hospitals in China, the use of spironolactone among ideal patients and the inappropriate use of spironolactone among patients with contraindications was substantial, with rates that varied markedly by institution.

Project description:BackgroundHospitalization for heart failure (HF) is associated with increased risk of death among patients with chronic HF. The degree to which hospitalization for HF is a distinct biologic entity with independent prognostic value versus a marker of higher risk chronic HF patients is unclear.MethodsAfter excluding patients with new-onset HF, the ASCEND-HF trial (Acute Study of Clinical Effectiveness of Nesiritide in Decompensated Heart Failure) included 4205 patients hospitalized for worsening chronic HF with reduced or preserved ejection fraction. The present analysis compared patients by presence or absence of prior HF hospitalization within 12 months and by timing of prior HF hospitalization relative to index hospitalization. Associations with 180-day all-cause mortality were assessed, including adjustment for 27 prespecified clinical factors.ResultsOverall, 2241 (53.3%) patients had a HF hospitalization within the prior 12 months and 1964 (46.7%) did not. Mortality rates at 180 days were 15.5% and 11.9%, respectively. In unadjusted analyses, prior HF hospitalization was associated with increased risk of 180-day mortality (HR, 1.35 [95% CI, 1.14-1.59]; P<0.01). After adjustment, the point estimate was attenuated and the association not statistically significant (HR, 1.18 [95% CI, 0.99-1.40]; P=0.064). Similarly, after adjustment, compared with patients without prior hospitalization, prior HF hospitalization was not associated with mortality, irrespective of timing (0-4 months: HR, 1.10 [95% CI, 0.87-1.39], P=0.41; 4-8 months: HR, 0.95 [95% CI, 0.70-1.27]; P=0.72; 8-12 months: HR, 1.06 [95% CI, 0.74-1.51], P=0.77; >12 months: HR, 0.81 [95% CI, 0.63-1.06], P=0.12).ConclusionsIn this cohort of patients hospitalized for worsening HF, prior HF hospitalization was not associated with 180-day mortality after comprehensively accounting for patient characteristics measured during the index patient visit. Clinical confounders measured at the point-of-care may explain previously observed associations between prior HF hospitalization and mortality, and these clinical factors may be a more direct means of predicting patient survival.
