Inpatient Mortality Risk Scores and Postdischarge Events in Hospitalized Heart Failure Patients: A Community-Based Study.

ABSTRACT: The Acute Decompensated Heart Failure National Registry (ADHERE) and Get With The Guidelines (GWTG) registries have developed simple heart failure (HF) in-hospital mortality risk scores. We hypothesized that HF scores predictive of in-hospital mortality would perform as well for early postdischarge mortality risk stratification.In this single-center, community-based, retrospective study of all consecutive primary HF hospitalizations (6203 hospitalizations in 3745 patients) from 2000 to 2013, the ADHERE and GWTG risk scores were calculated from admission data. There were 176 (3.0%) and 399 (6.7%), 869 (14.7%), and 1272 (21.5%) deaths in-hospital and at 30, 90, and 180 days postdischarge, respectively. The GWTG but not ADHERE risk score was well calibrated for in-hospital mortality. Both the ADHERE (C statistic 0.66 and 0.67, 0.64, and 0.64) and GWTG (C statistic 0.74 and 0.73, 0.71, and 0.70) HF risk scores were similarly predictive of in-hospital and 30-, 90-, and 180-day postdischarge mortality. The ADHERE risk score identified 10% and the GWTG risk score identified 20% of hospitalizations where 180-day postdischarge mortality was 50%, a prognostic bench mark for hospice referral. In contrast, hospitalizations characterized as lowest risk by the ADHERE (57% of hospitalizations; 180-day mortality 16.2%) or GWTG score (20% of hospitalizations; 180-day mortality 8.0%) had substantially lower mortality (odds ratios high versus low risk of 5-8 [ADHERE] and 11-18 [GWTG] across time points; P<0.0001 for all).The simple ADHERE and GWTG scores stratify hospitalized HF patients for both inpatient and early postdischarge mortality risk, allowing comprehensive risk assessment on admission.

Project description:Background In patients with heart failure (HF), malnutrition and dietary sodium excess are common and may worsen outcomes. No prior studies have provided low-sodium, nutritionally complete meals following HF hospitalization. Methods and Results The GOURMET-HF study (Geriatric Out-of-Hospital Randomized Meal Trial in Heart Failure) randomized patients discharged from HF hospitalization to 4 weeks of home-delivered sodium-restricted Dietary Approaches to Stop Hypertension meals (DASH/SRD; 1500 mg sodium/d) versus usual care. The primary outcome was the between-group change in the Kansas City Cardiomyopathy Questionnaire summary score from discharge to 4 weeks postdischarge. Additional outcomes included changes in the Kansas City Cardiomyopathy Questionnaire clinical summary score and cardiac biomarkers. All patients were followed 12 weeks for death/all-cause readmission and potential diet-related adverse events (symptomatic hypotension, hyperkalemia, acute kidney injury). Sixty-six patients were randomized 1:1 at discharge to DASH/SRD versus usual care (age, 71±8 years; 30% female; ejection fraction, 39±18%). The Kansas City Cardiomyopathy Questionnaire summary score increased similarly between groups (DASH/SRD 46±23-59±20 versus usual care 43±19-53±24; P=0.38), but the Kansas City Cardiomyopathy Questionnaire clinical summary score increase tended to be greater in DASH/SRD participants (47±22-65±19 versus 45±20-55±26; P=0.053). Potentially diet-related adverse events were uncommon; 30-day HF readmissions (11% versus 27%; P=0.06) and days rehospitalized within that timeframe (17 versus 55; P=0.055) trended lower in DASH/SRD participants. Conclusions Home-delivered DASH/SRD after HF hospitalization appeared safe in selected patients and had directionally favorable effects on HF clinical status and 30-day readmissions. Larger studies are warranted to clarify the effects of postdischarge nutritional support in patients with HF. Clinical Trial Registration URL: https://www.clinicaltrials.gov .
