Health-related quality of life post-discharge predicts one-year heart failure readmissions in patients over 80 years old, with predictors of poor quality of life varying by age.
Study objective: This study aims to identify predictors of health related quality of life (HRQoL) among patients with heart failure (HF) and assess whether HRQoL was a predictor of rehospitalisation and mortality, and if age influenced the findings. Design: Observational cohort study. Setting: Seven hospitals in the Northern Sydney Local Health District, Sydney, Australia. Participants: Community dwelling patients who completed a Minnesota Living with HF questionnaire (MLHFQ) within 30 days of discharge after a HF hospitalisation. Main outcome measure: Multivariable linear regression models were used to identify predictors of MLHFQ scores (higher score = worse HRQoL) and adjusted Cox regression models to assess the impact of MLHFQ scores on one-year rehospitalisation and mortality. Separate analyses were conducted for those aged ≤80 or >80 years. Results: 1911 patients of mean age 79 years (57 % aged >80 years) were included in this analysis. Among those aged ≤80 years; younger age, lower haemoglobin and presenting symptoms at hospitalisation of exertional dyspnoea, peripheral oedema and fatigue were predictors of worse post-discharge MLHFQ scores. In patients aged >80 years, living alone, chronic kidney disease, exertional dyspnoea and peripheral oedema were predictors of worse MLHFQ scores. Worse MLHFQ scores predicted one-year HF readmissions in those aged >80 years (HR 1.22, 95 % CI 1.07-1.37) but not those aged ≤80 years (HR 0.90 95 % CI 0.71-1.10). Conclusions: In-hospital predictors can be identified for worse HRQoL post-discharge for HF. These vary according to age, and should be addressed prior to discharge.
