Perception of impairments by patients with heart failure

Abstract

Background:

One of the major aims in the treatment of patients with heart failure (HF) is symptom relief and an improvement in the health-related quality of life (HR-QoL). The perception of impairments due to HF may differ between patients. A knowledge of the prevalence and perceived harshness of impairments due to HF is essential in providing personalized care on a patient level, in optimizing care on a population level and in finding the most appropriate patient-reported outcome for clinical trials.

Aim:

The aim of this study was to explore the prevalence and perceived harshness of impairments due to HF and the relation between perceived harshness and HR-QoL in patients with HF.

Methods and results:

The prevalence of impairments due to HF was assessed using items of the Minnesota Living with Heart Failure Questionnaire and the degree of perceived harshness was assessed using a structured self-assessment. A total of 100 outpatients (mean±SD age 70±9 years, 71% men) from an HF outpatient clinic were included. The prevalence of impairments was between 18 and 77%. The most prevalent impairments included tiredness and impairments in physical activity. Impairments that were frequently perceived as severely harsh included tiredness (67%), dyspnoea (57%) and impairments in physical activity (55%). Corrected item-total correlation (range 0.10–0.59) showed that tiredness (r=0.54) and impairments related to resting (r=0.59) and to participation in physical (r=0.52) and social (r=0.55) activities contributed highly to the sum-score of the Minnesota Living with Heart Failure Questionnaire.

Conclusion:

Highly prevalent impairments are not by definition perceived as severely harsh by patients with HF and do not contribute to the overall HR-QoL except for the impairments tiredness and working around the house/yard. These insights are important in providing personalized and optimized care for patients with HF.
