Investigating post-stroke fatigue: An individual participant data meta-analysis
Highlights
- •
- The first use of individual participant data meta-analysis in post-stroke fatigue.
- •
- Confirms links between fatigue after stroke and female sex, depression, disability.
- •
- Novel finding of greater fatigue with increased time since stroke.
- •
- A non-linear association between post-stroke fatigue and age.
Abstract
Objective
The prevalence of post-stroke fatigue
differs widely across studies, and reasons for such divergence are
unclear. We aimed to collate individual data on post-stroke fatigue from
multiple studies to facilitate high-powered meta-analysis, thus increasing our understanding of this complex phenomenon.
Methods
We
conducted an Individual Participant Data (IPD) meta-analysis on
post-stroke fatigue and its associated factors. The starting point was
our 2016 systematic review and meta-analysis of post-stroke fatigue
prevalence, which included 24 studies that used the Fatigue Severity
Scale (FSS). Study authors were asked to provide anonymised raw data on
the following pre-identified variables: (i) FSS score, (ii) age, (iii)
sex, (iv) time post-stroke, (v) depressive symptoms, (vi) stroke
severity, (vii) disability, and (viii) stroke type. Linear regression
analyses with FSS total score as the dependent variable, clustered by
study, were conducted.
Results
We
obtained data from 14 of the 24 studies, and 12 datasets were suitable
for IPD meta-analysis (total n = 2102). Higher levels of fatigue were
independently associated with female sex (coeff. = 2.13, 95% CI
0.44–3.82, p = 0.023), depressive symptoms (coeff. = 7.90, 95% CI
1.76–14.04, p = 0.021), longer time since stroke (coeff. = 10.38, 95% CI
4.35–16.41, p = 0.007) and greater disability (coeff. = 4.16, 95% CI
1.52–6.81, p = 0.010). While there was no linear association between
fatigue and age, a cubic relationship was identified (p < 0.001),
with fatigue peaks in mid-life and the oldest old.
Conclusion
Use
of IPD meta-analysis gave us the power to identify novel factors
associated with fatigue, such as longer time since stroke, as well as a
non-linear relationship with age.
