Identifying cut-off scores for interpretation of the Heart Failure Impact Questionnaire.

Aims: Heart failure (HF) influences health-related quality of life. However, the factors that contribute to health-related quality of life remain unclear in Taiwan. We aim to identify the factors influencing health-related quality of life in HF patients.

Methods: Hospitalized HF ( N  = 225) patients were included from April 2011 to April 2014. Health-related quality of life was assessed by using the 36-Item Short-Form Health Survey (SF-36) and the Minnesota Living with Heart Failure Questionnaire. A new cut-off was conducted based on the combination of SF-36 and Minnesota Living with Heart Failure questionnaire.

Results: There were significant differences between good and poor quality groups on age, gender, education levels, occupational classification caregiver, New York Heart Association classes, and the numbers of comorbidities. The logistic regression analysis showed that the number of comorbidities was more than three and New York Heart Association class IV were significantly associated with health-related quality of life.
