Key result
High fatigue was present in 73.6% of patients before cardiac surgery and significantly decreased over 6 months, with poor sleep quality significantly associated with increased fatigue (p<0.001).
Why the study?
Investigating longitudinal changes in fatigue and its associated factors in patients undergoing cardiac surgery was needed to inform interventions to improve fatigue during recovery.
Population
125 patients undergoing cardiac surgery in northern Taiwan
Design
Longitudinal study
Follow-up
6 months post-discharge

Social support increases linked to higher fatigue post-surgery; hypothesis-generating and should not yet guide interventions.
Observational (n=125)
Fatigue is highly prevalent before cardiac surgery but generally decreases over 6 months post-discharge, with symptom distress, poor sleep, and psychosocial factors being key drivers of persistent fatigue.
Chou et al. (2022) conducted an observational in Cardiac surgery (n=125). Clinical and psychosocial factors (e.g., sleep quality, social support) was evaluated on Fatigue trajectory measured by the General Fatigue Scale. High fatigue was present in 73.6% of patients before cardiac surgery and significantly decreased over 6 months, with poor sleep quality significantly associated with increased fatigue (p<0.001).
