Patients hospitalized with acute heart failure, worsening renal function, and persistent congestion are at high risk for adverse outcomes despite current medical therapy

INTRODUCTION: Approximately 1/3 of patients with acute decompensated heart failure (ADHF) are discharged with persistent congestion. Worsening renal function (WRF) occurs in approximately 50% of patients hospitalized for ADHF and the combination of WRF and persistent congestion are associated with higher risk of mortality and HF readmissions. METHODS: We designed a multicenter, prospective registry to describe current treatments and outcomes for patients hospitalized with ADHF complicated by WRF (defined as a creatinine increase ≥0.3 mg/dL) and persistent congestion at 96 h. Study participants were followed during the hospitalization and through 90-day post-discharge. Hospitalization costs were analyzed in an economic substudy. RESULTS: We enrolled 237 patients hospitalized with ADHF, who also had WRF and persistent congestion. Among these, the average age was 66 ± 13 years and 61% had a left ventricular ejection fraction (LVEF) ≤ 40%. Mean baseline creatinine was 1.7 ± 0.7 mg/dL. Patients with persistent congestion had a high burden of clinical events during the index hospitalization (7.6% intensive care unit transfer, 2.1% intubation, 1.7% left ventricular assist device implantation, and 0.8% dialysis). At 90-day follow-up, 33% of patients were readmitted for ADHF or died. Outcomes and costs were similar between patients with reduced and preserved LVEF. CONCLUSIONS: Many patients admitted with ADHF have WRF and persistent congestion despite diuresis and are at high risk for adverse events during hospitalization and early follow-up. Novel treatment strategies are urgently needed for this high-risk population

Health System-Level Performance in Prescribing Guideline-Directed Medical Therapy for Patients with HFrEF: Results from the CONNECT-HF Trial

BACKGROUND: Health system-level interventions to improve use of guideline-directed medical therapy (GDMT) often fail in the acute care setting. We sought to identify factors associated with high performance in adoption of GDMT among health systems in CONNECT-HF. METHODS AND RESULTS: Site-level composite quality scores were calculated at discharge and last follow-up. Site performance was defined as the average change in score from baseline to last follow-up and analyzed by performance tertile using a mixed-effects model with baseline performance as a fixed effect and site as a random effect. Among 150 randomized sites, mean 12-month improvement in GDMT was 1.8% (-26.4% to 60.0%). Achievement of ≥50% target dose for angiotensin-converting enzymes/angiotensin receptor blockers/angiotensin receptor-neprilysin inhibitors and beta blockers at 12 months was modest, even at the highest performing sites (median 29.6% [23%, 41%] and 41.2% [29%, 50%]). Sites achieving higher GDMT scores had care teams that included social workers and pharmacists and patients able to afford medications and access medication lists in the electronic health record. CONCLUSIONS: Substantial gaps in site-level use of GDMT were found even among highest performing sites. Failure of hospital-level interventions to improve quality metrics suggests that a team-based approach to care and improved patient access to medications are needed for post-discharge success
