ABSTRACT
BACKGROUND: Acute decompensated heart failure (ADHF) is a leading cause of cardiovascular disease hospitalisations associated with significant morbidity and mortality. In hospitals, HF patients are typically managed by cardiology or physician teams, with differences in patient demographics and clinical outcomes. This study utilises contemporary HF registry data to compare patient characteristics and outcomes in those with ADHF admitted into General Medicine and Cardiology units. METHODS: The Victorian Cardiac Outcomes Registry was utilised to identify patients hospitalised with ADHF 30-day period in each of four consecutive years. We compared patient characteristics, pharmacological management and outpatient follow-up of patients admitted to General Medicine and Cardiology units. Primary outcome measures included in-hospital mortality, 30-day readmission, and 30-day mortality. RESULTS: Between 2014 and 2017, a total of 1,253 patients with ADHF admissions were registered, with 53% admitted in General Medicine units and 47% in Cardiology units. General Medicine patients were more likely to be older (82 vs 71 years; p<0.001), female (51% vs 34%; p<0.001), and have higher prevalence of comorbidities and preserved left ventricular function (p<0.001). There were no differences in primary outcome measures between General Medicine and Cardiology in terms of: in-hospital mortality (5.0% vs 3.9%; p=0.35), 30-day readmission (23.4% vs 23.6%; p=0.93), and 30-day mortality (10.0% vs 8.0%; p=0.21). CONCLUSIONS: Hospitalised patients with HF continue to have high mortality and rehospitalisation rates. The choice of treatment by General Medicine or Cardiology units, based on the particular medical profile and individual needs of the patients, provides equivalent outcomes.
ABSTRACT
BACKGROUND: Late referral for heart transplantation (HTx) is associated with worse patient outcomes. There are no universally accepted definitions of what constitutes a timely referral for HTx assessment. OBJECTIVES: To evaluate the impact of late referral (LR) on HTx outcomes. METHODS: This single-centre retrospective observational study included 80 patients undergoing HTx between 2016-2019. We applied a simple clinical tool, derived from markers of advanced heart failure (HF), to classify LR in HTx patients and assess the impact of LR on HTx outcomes. Outcome measures included duration of intensive care unit (ICU) stay, total hospitalisation stay, cost of transplant admission and one-year mortality. RESULTS: Based upon the clinical profile, LR was defined by the presence of four or more out of 10 criteria for more than 6 months in HTx patients. In this model, 34 patients were timely referrals and 46 were LR. Patients who were LR had: a longer median time between initial diagnosis and referral (3 vs 7 ys; p=0.03); more features of advanced HF, including inotrope requirements (p=0.004); more comorbidities (p=0.014); and hospitalisations (p<0.0001). Late referral was not associated with longer ICU (p=0.14) or hospital stay (p=0.051), however LR incurred greater total in-hospital costs (p=0.011). There was no difference in one-year mortality (6% vs 9%; p=0.64). CONCLUSION: Patients referred late for HTx are more unwell at time of referral and require greater in-hospital resource usage at the time of transplantation. Earlier referral for transplant assessment in patients with advanced HF should be encouraged.
