OBJECTIVE: Perceived fatigue significantly impacts quality of life after burns, yet how often it occurs is unknown. Therefor this study assessed the prevalence of perceived fatigue of burn survivors.

METHODS: In February 2023, a systematic literature search was performed in CINAHL, Embase, PsycInfo, PubMed and Web of Science. Studies reporting the prevalence of post-burn perceived fatigue were included.

RESULTS: In ten cross-sectional studies of moderate-high quality with measurements between 5.3 days and 42 years post burn, the prevalence of perceived fatigue varied between 5 % and 78 % with no apparent time trends. Broad study populations hindered explaining this varying prevalence by age or %TBSA. In four high-quality longitudinal studies with 3-5 measurements between 1 and 24 months post burn, the prevalence decreased over time, dropping from approximately 70 to 50 % in adults and 65 to 28 % in children. Studies used various measurement instruments and cut-off points for operationalizing perceived fatigue, severely limiting the interpretation and comparison of prevalence rates across studies.

CONCLUSIONS: The high prevalence and persistent nature of perceived fatigue among burn survivors emphasize its crucial role in burn rehabilitation. Future studies should prioritize identifying individuals with adverse trajectories of perceived fatigue and unravelling underlying mechanisms to develop effective treatments for reducing post-burn perceived fatigue.
