Personalised Cardiac Rehabilitation Outreach Service Reduces Mortality and Hospitalisations in Heart Failure with Reduced Ejection Fraction

BackgroundHeart failure (HF) has become a major cause of morbidity and mortality worldwide. Despite significant improvements in the management of HF, the overall outcomes remain poor. In addition to pharmacotherapy and device therapy, non-pharmacological interventions are needed to mitigate the effects of this illness. The aim of this study was to evaluate the impact of the heart failure outreach program on the rate of mortality, HF hospitalisations and guideline directed medical therapy (GDMT) for HF in South Western Sydney Local Health District (SWSLHD). MethodsIn this observational, registry based study, adult patients diagnosed with Heart failure with reduced ejection fraction (HFrEF) within the South Western Sydney Local Health District (SWSLHD) and invited to participate in the heart failure outreach service between March 2011 and January 2016 were included in the study. The primary outcome was all-cause mortality. In addition, we examined the rate of optimal medical therapy, HF hospitalisations and the total lengths of stay. ResultsA total of 818 patients were included in the study; 470 (57.5%) patients were enrolled and 348 (42.5 %) not enrolled into the program. At the end of the follow up period (median 978 days, interquartile range (IQR) 720-1237), the primary outcome of mortality was observed significantly less in the enrolled group (122 (26%) vs. 133 (38.2%), p<0.001) independently of other variables. In addition, significantly fewer enrolled patients had >3 hospital admissions for HF (16.2% vs. 35.6%, p<0.001) and reduced median admission days (14.5 days [IQR 8-25] vs 22 [IQR 12-37], p <0.001). Patients enrolled into the program were much more likely to be on GDMT (76.6% vs 56.6%, p<0.001). ConclusionsEnrolment in the heart failure outreach program was associated with a significant reduction in mortality as well as a reduction in the frequency and length of hospital admissions. In addition, the rate of GDMT was significantly higher in the enrolled group. With the high prevalence of heart failure, these programs should be considered in the routine management of patients with HFrEF.
