Fatigue after heart transplantation – a possible barrier to self‐efficacy

RATIONALE: Recovery after heart transplantation is challenging and many heart recipients struggle with various transplant‐related symptoms, side‐effects of immunosuppressive medications and mental challenges. Fatigue has been reported to be one of the most common and distressing symptoms after heart transplantation and might therefore constitute a barrier to self‐efficacy, which acts as a moderator of self‐management. AIM: To explore the prevalence of fatigue and its relationship to self‐efficacy among heart recipients 1–5 years after transplantation. RESEARCH METHOD: An explorative cross‐sectional design, including 79 heart recipients due for follow‐up 1–5 years after transplantation. Three different self‐assessment instruments were employed; The Multidimensional Fatigue Inventory‐19, Self‐efficacy for managing chronic disease 6‐Item Scale and The Postoperative Recovery Profile. ETHICAL APPROVAL: The study was approved by the Regional Ethics Board of Lund (Dnr. 2014/670‐14/10) with supplementary approval from the Swedish Ethical Review Authority (Dnr. 2019‐02769). RESULTS: The reported levels of fatigue for the whole group were moderate in all dimensions of the Multidimensional Fatigue Inventory‐19, with highest ratings in the General Fatigue sub‐scale. Those most fatigued were the groups younger than 50 years; pretransplant treatment with Mechanical Circulatory Support; not recovered or had not returned to work. Self‐efficacy was associated with the sub‐dimensions Mental Fatigue (ρ = −0·.649) and Reduced Motivation (ρ = −0·617), which explained 40·1% of the variance when controlled for age and gender. STUDY LIMITATIONS: The small sample size constitutes a limitation. CONCLUSIONS: The moderate levels of fatigue reported indicate that it is not a widespread problem. However, for those suffering from severe fatigue it is a troublesome symptom that affects the recovery process and their ability to return to work. Efforts should be made to identify those troubled by fatigue to enable sufficient self‐management support.
