    (Public Library of Science, 2022-07-26) Han, Jin H.; McNaughton, Candace D.; Stubblefield, William B.; Pang, Peter S.; Levy, Phillip D.; Miller, Karen F.; Meram, Sarah; Cole, Mette Lind; Jenkins, Cathy A.; Paz, Hadassah H.; Moser, Kelly M.; Storrow, Alan B.; Collins, Sean P.; Emergency Medicine Research and Outcomes Consortium Investigators; Emergency Medicine, School of Medicine
    Younger patients (18 to 65 years old) are often excluded from delirium outcome studies. We sought to determine if delirium was associated with short-term adverse outcomes in a diverse cohort of younger and older patients with acute heart failure (AHF). We conducted a multi-center prospective cohort study that included adult emergency department patients with confirmed AHF. Delirium was ascertained using the Brief Confusion Assessment Method (bCAM). The primary outcome was a composite outcome of 30-day all-cause death, 30-day all-cause rehospitalization, and prolonged index hospital length of stay. Multivariable logistic regression was performed, adjusting for demographics, cognitive impairment without delirium, and HF risk factors. Older age (≥ 65 years old)*delirium interaction was also incorporated into the model. Odds ratios (OR) with their 95% confidence intervals (95%CI) were reported. A total of 1044 patients with AHF were enrolled; 617 AHF patients were < 65 years old and 427 AHF patients were ≥ 65 years old, and 47 (7.6%) and 40 (9.4%) patients were delirious at enrollment, respectively. Delirium was significantly associated with the composite outcome (adjusted OR = 1.64, 95%CI: 1.02 to 2.64). The older age*delirium interaction p-value was 0.47. In conclusion, delirium was common in both younger and older patients with AHF and was associated with poorer short-term outcomes in both cohorts. Younger patients with acute heart failure should be included in future delirium outcome studies.

    Effect of a Self-care Intervention on 90-Day Outcomes in Patients With Acute Heart Failure Discharged From the Emergency Department: A Randomized Clinical Trial
    (American Medical Association, 2021) Collins, Sean P.; Liu, Dandan; Jenkins, Cathy A.; Storrow, Alan B.; Levy, Phillip D.; Pang, Peter S.; Chang, Anna Marie; Char, Douglas; Diercks, Deborah J.; Fermann, Gregory J.; Han, Jin H.; Hiestand, Brian; Hogan, Christopher; Kampe, Christina J.; Khan, Yosef; Lee, Sangil; Lindenfeld, JoAnn; Martindale, Jennifer; McNaughton, Candace D.; Miller, Karen F.; Miller-Reilly, Carolyn; Moser, Kelly; Peacock, W. Frank; Robichaux, Chad; Rothman, Russell; Schrock, Jon; Self, Wesley H.; Singer, Adam J.; Sterling, Sarah A.; Ward, Michael J.; Walsh, Cheryl; Butler, Javed; Emergency Medicine, School of Medicine
    Importance: Up to 20% of patients who present to the emergency department (ED) with acute heart failure (AHF) are discharged without hospitalization. Compared with rates in hospitalized patients, readmission and mortality are worse for ED patients. Objective: To assess the impact of a self-care intervention on 90-day outcomes in patients with AHF who are discharged from the ED. Design, setting, and participants: Get With the Guidelines in Emergency Department Patients With Heart Failure was an unblinded, parallel-group, multicenter randomized trial. Patients were randomized 1:1 to usual care vs a tailored self-care intervention. Patients with AHF discharged after ED-based management at 15 geographically diverse EDs were included. The trial was conducted from October 28, 2015, to September 5, 2019. Interventions: Home visit within 7 days of discharge and twice-monthly telephone-based self-care coaching for 3 months. Main outcomes and measures: The primary outcome was a global rank of cardiovascular death, HF-related events (unscheduled clinic visit due to HF, ED revisit, or hospitalization), and changes in the Kansas City Cardiomyopathy Questionnaire-12 (KCCQ-12) summary score (SS) at 90 days. Key secondary outcomes included the global rank outcome at 30 days and changes in the KCCQ-12 SS score at 30 and 90 days. Intention-to-treat analysis was performed for the primary, secondary, and safety outcomes. Per-protocol analysis was conducted including patients who completed a home visit and had scheduled outpatient follow-up in the intervention arm. Results: Owing to slow enrollment, 479 of a planned 700 patients were randomized: 235 to the intervention arm and 244 to the usual care arm. The median age was 63.0 years (interquartile range, 54.7-70.2), 302 patients (63%) were African American, 305 patients (64%) were men, and 178 patients (37%) had a previous ejection fraction greater than 50%. There was no significant difference in the primary outcome between patients in the intervention vs usual care arm (hazard ratio [HR], 0.89; 95% CI, 0.73-1.10; P = .28). At day 30, patients in the intervention arm had significantly better global rank (HR, 0.80; 95% CI, 0.64-0.99; P = .04) and a 5.5-point higher KCCQ-12 SS (95% CI, 1.3-9.7; P = .01), while at day 90, the KCCQ-12 SS was 2.7 points higher (95% CI, -1.9 to 7.2; P = .25). Conclusions and relevance: The self-care intervention did not improve the primary global rank outcome at 90 days in this trial. However, benefit was observed in the global rank and KCCQ-12 SS at 30 days, suggesting that an early benefit of a tailored self-care program initiated at an ED visit for AHF was not sustained through 90 days.

    Improvement in Kansas City Cardiomyopathy Questionnaire Scores After a Self-Care Intervention in Patients With Acute Heart Failure Discharged From the Emergency Department
    (American Heart Association, 2021) Stubblefield, William B.; Jenkins, Cathy A.; Liu, Dandan; Storrow, Alan B.; Spertus, John A.; Pang, Peter S.; Levy, Phillip D.; Butler, Javed; Chang, Anna Marie; Char, Douglas; Diercks, Deborah B.; Fermann, Gregory J.; Han, Jin H.; Hiestand, Brian C.; Hogan, Christopher J.; Khan, Yosef; Lee, Sangil; Lindenfeld, JoAnn M.; McNaughton, Candace D.; Miller, Karen; Peacock, W. Frank; Schrock, Jon W.; Self, Wesley H.; Singer, Adam J.; Sterling, Sarah A.; Collins, Sean P.; Emergency Medicine, School of Medicine
    Background: We conducted a secondary analysis of changes in the Kansas City Cardiomyopathy Questionnaire (KCCQ)-12 over 30 days in a randomized trial of self-care coaching versus structured usual care in patients with acute heart failure who were discharged from the emergency department. Methods: Patients in 15 emergency departments completed the KCCQ-12 at emergency department discharge and at 30 days. We compared change in KCCQ-12 scores between the intervention and usual care arms, adjusted for enrollment KCCQ-12 and demographic characteristics. We used linear regression to describe changes in KCCQ-12 summary scores and logistic regression to characterize clinically meaningful KCCQ-12 subdomain changes at 30 days. Results: There were 350 patients with both enrollment and 30-day KCCQ summary scores available; 166 allocated to usual care and 184 to the intervention arm. Median age was 64 years (interquartile range, 55-70), 37% were female participants, 63% were Black, median KCCQ-12 summary score at enrollment was 47 (interquartile range, 33-64). Self-care coaching resulted in significantly greater improvement in health status compared with structured usual care (5.4-point greater improvement, 95% CI, 1.12-9.68; P=0.01). Improvements in health status in the intervention arm were driven by improvements within the symptom frequency (adjusted odds ratio, 1.62 [95% CI, 1.01-2.59]) and quality of life (adjusted odds ratio, 2.39 [95% CI, 1.46-3.90]) subdomains. Conclusions: In this secondary analysis, patients with acute heart failure who received a tailored, self-care intervention after emergency department discharge had clinically significant improvements in health status at 30 days compared with structured usual care largely due to improvements within the symptom frequency and quality of life subdomains of the KCCQ-12.

    Troponin is unrelated to outcomes in heart failure patients discharged from the emergency department
    (Wiley, 2022-04-09) Fermann, Gregory J.; Schrock, Jon W.; Levy, Phillip D.; Pang, Peter; Butler, Javed; Chang, Anna Marie; Char, Douglas; Diercks, Deborah; Han, Jin H.; Hiestand, Brian; Hogan, Chris; Jenkins, Cathy A.; Kampe, Christy; Khan, Yosef; Kumar, Vijaya A.; Lee, Sangil; Lindenfeld, JoAnn; Liu, Dandan; Miller, Karen F.; Peacock, W.

    Background: Prior data has demonstrated increased mortality in hospitalized patients with acute heart failure (AHF) and troponin elevation. No data has specifically examined the prognostic significance of troponin elevation in patients with AHF discharged after emergency department (ED) management. Objective: Evaluate the relationship between troponin elevation and outcomes in patients with AHF who are treated and released from the ED. Methods: This was a secondary analysis of the Get with the Guidelines to Reduce Disparities in AHF Patients Discharged from the ED (GUIDED-HF) trial, a randomized, controlled trial of ED patients with AHF who were discharged. Patients with elevated conventional troponin not due to acute coronary syndrome (ACS) were included. Our primary outcome was a composite endpoint: time to 30-day cardiovascular death and/or heart failure-related events. Results: Of the 491 subjects included in the GUIDED-HF trial, 418 had troponin measured during the ED evaluation and 66 (16%) had troponin values above the 99th percentile. Median age was 63 years (interquartile range, 54-70), 62% (n = 261) were male, 63% (n = 265) were Black, and 16% (n = 67) experienced our primary outcome. There were no differences in our primary outcome between those with and without troponin elevation (12/66, 18.1% vs 55/352, 15.6%; P = 0.60). This effect was maintained regardless of assignment to usual care or the intervention arm. In multivariable regression analysis, there was no association between our primary outcome and elevated troponin (hazard ratio, 1.00; 95% confidence interval, 0.49-2.01, P = 0.994). Conclusion: If confirmed in a larger cohort, these findings may facilitate safe ED discharge for a group of patients with AHF without ACS when an elevated troponin is the primary reason for admission.
