Associations between seattle heart failure model scores and medical resource use and costs: findings from HF-ACTION.

ABSTRACT: Prognostic models, such as the Seattle Heart Failure Model (SHFM), have been developed to predict patient survival. The extent to which they predict medical resource use and costs has not been explored. In this study, we evaluated relationships between baseline SHFM scores and 1-year resource use and costs using data from a clinical trial.We applied generalized linear models to examine the relative impact of a 1-unit increase in SHFM scores on counts of medical resource use and direct medical costs at 1 year of follow-up. Of 2331 randomized patients, 2288 (98%) had a rounded integer SHFM score between -1 and 2, consistent with predicted 1-year survival of 98% and 74%, respectively. At baseline, median age was 59 years, 28% of patients were women, and nearly two-thirds of the cohort had New York Heart Association class II heart failure and one-third had class III heart failure. Higher SHFM scores were associated with more hospitalizations (rate ratio per 1-unit increase, 1.86; P < .001), more inpatient days (2.30; P < .001), and higher inpatient costs (2.28; P < .001), outpatient costs (1.54; P < .001), and total medical costs (2.13; P < .001).Although developed to predict all-cause mortality, SHFM scores also predict medical resource use and costs.

Project description:BackgroundIron deficiency is common in heart failure and associated with worse outcomes. We examined the prevalence and consequences of iron deficiency in the DAPA-HF trial (Dapagliflozin and Prevention of Adverse-Outcomes in Heart Failure) and the effect of dapagliflozin on markers of iron metabolism. We also analyzed the effect of dapagliflozin on outcomes, according to iron status at baseline.MethodsIron deficiency was defined as a ferritin level <100 ng/mL or a transferrin saturation <20% and a ferritin level 100 to 299 ng/mL. Additional biomarkers of iron metabolism, including soluble transferrin receptor, erythropoietin, and hepcidin were measured at baseline and 12 months after randomization. The primary outcome was a composite of worsening heart failure (hospitalization or urgent visit requiring intravenous therapy) or cardiovascular death.ResultsOf the 4744 patients randomized in DAPA-HF, 3009 had ferritin and transferrin saturation measurements available at baseline, and 1314 of these participants (43.7%) were iron deficient. The rate of the primary outcome was higher in patients with iron deficiency (16.6 per 100 person-years) compared with those without (10.4 per 100 person-years; P<0.0001). The effect of dapagliflozin on the primary outcome was consistent in iron-deficient compared with iron-replete patients (hazard ratio, 0.74 [95% CI, 0.58-0.92] versus 0.81 [95% CI, 0.63-1.03]; P-interaction=0.59). Similar findings were observed for cardiovascular death, heart failure hospitalization, and all-cause mortality. Transferrin saturation, ferritin, and hepcidin were reduced and total iron-binding capacity and soluble transferrin receptor increased with dapagliflozin compared with placebo.ConclusionsIron deficiency was common in DAPA-HF and associated with worse outcomes. Dapagliflozin appeared to increase iron use but improved outcomes, irrespective of iron status at baseline.RegistrationURL: https://www.Clinicaltrialsgov; Unique identifier: NCT03036124.

Project description:Background and objectivesHeart failure (HF) is one of the leading causes of morbidity and mortality, and economic burden on the healthcare system. The aim of this study was to estimate the current hospital resource utilization and costs for HF patients in France.MethodsThis retrospective cohort study included adult HF patients hospitalized in France between January 1, 2019 and December 31, 2019. Data related to sociodemographic characteristics, number and duration of hospital stays, use of medical procedures or expensive and innovative drugs/medical devices included in the "liste-en-sus", and comorbidities were retrieved from the French national hospital discharge database. Data were further stratified based on the presence or absence of cardiac decompensation, comorbidities, ejection fraction (EF) status, and incident/prevalent patients.ResultsIn 2019, a total of 430,544 patients were hospitalized in France with HF as a primary or associated diagnosis, with 51.9% male and 48.1% female and a mean age of 79.0 years. More than 75% of the study population was composed of prevalent HF patients. About 3.1% of patients were diagnosed with at least one event of cardiac decompensation during follow-up. Also, 20.2% and 9.9% of patients were identified with preserved and reduced EFs, respectively. The average number and length of hospital stays were 1.7 per patient and 10.4 days per patient, respectively. The annual cost of hospitalization for HF was €8341.3 per patient. Presence of cardiac decompensation at index date or during follow-up, reduced EF, and comorbidities were associated with numerically higher frequency and length of hospitalization, and hospitalization cost. For hospitalization and 'liste-en-sus' medical devices, higher cost was observed in incident than prevalent HF patients, while for 'liste-en-sus' drugs, higher cost was reported in prevalent than incident HF patients.ConclusionThis study highlighted the high economic hospital burden of HF in France. More studies investigating different HF patient profiles must be conducted to help determine the main factors of hospital cost for HF.
