  • Purpose
    To evaluate heart failure knowledge and adherence to selfcare behaviors, andto identify factors affecting adherence to self-care behaviors among Korean patients with heart failure.
  • Methods
    Correlational research using the European Heart Failure Self-care Behavior Scale, the Duke Activity Status Index, the Dutch Heart Failure Knowledge Scale, the New York Heart Association Functional Classification, and the Medical Outcomes Study Social Support Survey was conducted. A total of 280 outpatients with heart failure responded to the five questionnaires.
  • Results
    The mean scores for self-care adherence and heart failure knowledge were 31.98 ± 6.81 and 8.78 ± 2.53, respectively, indicating lower adherence and knowledge than those previously reported. Subjects with lower functional status, more social supports, and greater knowledge of heart failure are more likely to adhere to prescribed regimens.
  • Conclusion
    Nurses should focus on patient education and support to improve their adherence to self-care behaviors.
