Management of Acute Decompensated Heart Failure in Rural Versus Metropolitan Settings: An Australian Experience.

BACKGROUND: Acute decompensated heart failure (ADHF) is the most common cause of hospital admission in patients over 65, with poorer outcomes demonstrated in rural versus metropolitan areas. The aim of this study was to compare the in-hospital and post-discharge management of ADHF patients admitted to rural versus metropolitan hospitals in Victoria. METHODS: Data from the Victorian Cardiac Outcomes Registry, Heart Failure (VCOR-HF) project was used. This was a prospective, observational, non-randomised study of consecutive patients admitted to participating hospitals in Victoria, Australia, with ADHF as their primary diagnosis over four 30-day periods during consecutive years. All patients were followed up for 30 days post discharge. RESULTS: 1,357 patients (1,260 metropolitan, 97 rural) were admitted to study hospitals with ADHF during the study periods. Cohorts were similar in age (average 76.87±13.12 yrs) and percentage of male gender (56.4% overall). Metropolitan patients were more likely to have diabetes (44.4% vs 34.0%, p=0.046), kidney disease (65.8% vs 37.1%, p<0.01) and anaemia (31.9% vs 19.6%, p=0.01). There was no significant difference in length of stay between metropolitan and rural patients (7.49 vs 6.37 days, p=0.12). There was no significant difference between metropolitan and rural patients in 30-day rehospitalisations (19.1% vs 11.6%, p=0.07, respectively) and all-cause 30-day mortality (8.2% vs 4.1%, p=0.15, respectively). Metropolitan patients were significantly more likely to have seen their general practitioner (GP) (68.1% vs 53.2%, p<0.01) or attend an outpatient clinic (35.9% vs 10.6%, p<0.01) by 30 days. There was no significant difference in number of days to follow-up of any kind between groups. Referrals to a heart failure home visiting program remained low overall (19.9%). CONCLUSION: There was no significant difference in 30-day rehospitalisations or mortality between patients admitted to rural versus metropolitan hospitals. Geographical discrepancies were noted in follow-up by 30 days, with significantly more metropolitan patients having seen a doctor by 30 days post-discharge. Overall follow-up rates remain suboptimal.

Impact of Individual Patient Profiles on Adherence to Guideline Directed Medical Therapy in Heart Failure With Reduced Ejection Fraction: VCOR-HF Study.

BACKGROUND: Multiple co-morbidities complicate initiation of medical therapy in patients with heart failure with reduced ejection fraction (HFrEF). Adherence to guidelines based on individual patient profiles is not well described. This paper examines the effect of individual patient profiles on guideline recommended therapies for HFrEF. METHODS: This was a prospective, observational, non-randomised study of hospitalised HFrEF patients over 30 days, from 2014 to 2017 in 16 hospitals. A previously developed algorithm-based guideline adherence score was used to determine adherence to key performance indicators: prescribing of beta blockers, angiotensin converting enzyme inhibitors (ACEIs), angiotensin receptor blockers (ARBs), mineralocorticoid-receptor antagonist (MRAs) for HFrEF patients and early outpatient and heart failure (HF) disease management program review. Patients were classified as low, moderate and excellent adherence to medical therapy. RESULTS: Of the 696 HFrEF patients, 69.1% (n=481) were male with an average age of 73.15 years (SD±14.5 years). At discharge, 64.6% (n=427) were prescribed an ACEI/ARB, 78.7% (n=525) a beta blocker and 45.3% (n=302) prescribed MRA. Based on individual patient profiles, 18.2% (n=107) of eligible patients received an outpatient clinic and HF disease management program review within 30 days and 41.5% (n=71) were prescribed triple therapy. Based on individual profiles, 13% (n=21) of patients received an excellent guideline adherence score. CONCLUSION: Individual patient profiles impact on adherence to guideline recommendations. Review in transitional care and prescribing of triple pharmacotherapy is suboptimal. Translational strategies to facilitate the implementation of guideline recommended therapies is warranted.

The Effect of Transitional Care on 30-Day Outcomes in Patients Hospitalised With Acute Heart Failure.

BACKGROUND: Patients admitted to hospital with acute heart failure (AHF) are at increased risk of readmission and mortality post-discharge. The aim of the study was to examine health service utilisation within 30 days post-discharge from an AHF hospitalisation. METHODS: This was a prospective, observational, non-randomised study of consecutive patients hospitalised with acute HF to one of 16 Victorian hospitals over a 30-day period each year and followed up for 30 days post-discharge. The project was conducted annually over three consecutive years from 2015 to 2017. RESULTS: Of the 1,197 patients, 56.3% were male with an average age of 77±13.23 years. Over half of the patients (711, 62.5%) were referred to an outpatient clinic and a third (391, 34.4%) to a HF disease management program. In-hospital mortality was 5.1% with 30 day-mortality of 9% and readmission rate of 24.4%. Patients who experienced a subsequent readmission less than 10 days post-discharge and between 11 and 20 days post-discharge had a five- to six-fold increase in risk of mortality (adjusted OR 5.02, 95% CI 2.11-11.97; OR 6.45, 95% CI 2.69-15.42; respectively) compared to patients who were not readmitted to hospital. An outpatient appointment within 30 days post-discharge significantly reduced the risk of 30-day mortality by 81% (95% CI 0.09-0.43). CONCLUSION: Patients admitted to hospital with AHF who experience a subsequent readmission within 20 days post-discharge are at increased risk of dying. However, early follow-up post-discharge may reduce this risk. Early post-discharge follow-up is vital to address this vulnerable period after a HF admission.

Medium-Term Bioresorbable Scaffold Outcomes Utilising Data From an Australian Clinical Quality Registry.

BACKGROUND: Bioresorbable scaffolds (BRS) are a novel technology in coronary intervention. However, recent trials demonstrate higher rates of device failure compared to contemporary drug-eluting stents. This study sought to utilise a clinical quality registry to assess the medium-term safety of the Abbott Absorb BRS (Abbott Vascular, Santa Clara, CA, USA), in an Australian context. METHODS: A prospective, observational study of 192 BRS percutaneous coronary interventions (PCI) compared to 31,773 non-BRS PCIs entered in the Victorian Cardiac Outcomes Registry from 2013 to 2017. The main outcome measure was patient-oriented composite endpoint (POCE) events comprising all-cause mortality, any myocardial infarction (MI), and any revascularisation. RESULTS: Bioresorbable scaffolds patients (mean age 61.6±10.5 years, 79% male) were younger, had less comorbidity, less prior PCI, fewer ST elevation myocardial infarction (STEMI) presentations, lower rates of multi-lesion disease and more adjuvant devices compared to non-BRS PCI (all p<0.01). All-cause mortality was 2.1%, myocardial infarction (MI) 2.1%, scaffold thrombosis 3.1% and any revascularisation 14.1% (mean follow-up 27.4±8.9 months). POCE events occurred in 11.5% at 1 year and 16.9% at 2 years, comparable to pooled-trial data. Multivariate predictors of POCE were >1 scaffold used (odds ratio [OR] 4.6, 95% confidence interval [CI] 1.9-11.4, p<0.01) and scaffold diameter ≤2.5 mm (OR 3.3, 95% CI 1.4-7.6, p=0.02). Over 95% guideline adherence was achieved in six of eight patient selection criteria and four of six device deployment criteria. CONCLUSION: In an Australian setting, BRS were used in non-complex patients. Most guidelines for use were adhered to and outcomes were comparable to pooled trial data. Clinical quality registries are effective in assessing novel treatments and technologies when potential safety concerns develop.
