Abstract​

Objective To assess the clinical effectiveness of non-pharmacological interventions for fatigue in adults with long term medical conditions.

Design Systematic review and network meta-analysis.

Data sources Medline, Embase, CINAHL, APA PsycInfo, Web of Science Core Collection, and the Cochrane Central Register of Controlled Trials, from database inception to 28 September-3 October 2023, and updated 23-24 September 2024.

Eligibility criteria for selecting studies Randomised controlled trials of non-pharmacological interventions for fatigue in long term medical conditions where fatigue was a criterion for inclusion, the primary target of the intervention, or the primary or co-primary outcome. Excluded were studies of fatigue in people with cancer, in relation to or after infection, or resulting from injuries or developmental disorders. Studies were limited to European-style healthcare systems.

Results 88 randomised controlled trials were included, comprising 6636 participants for the end of treatment analyses, 1849 participants for the short term (≤3 months after the end of treatment) analyses, and 2322 participants for the long term (>3 months) analyses, allocated to one of 27 interventions. The most common condition studied was multiple sclerosis (51 studies). A range of interventions were identified, and heterogeneity was found within intervention groups and between individual interventions. Interventions varied by duration, delivery methods, and intensity. Compared with usual care, interventions based on cognitive behavioural therapy (CBT) significantly reduced fatigue at the end of treatment (standardised mean difference −0.63, 95% credible interval (CrI) −0.87 to −0.40, 17 studies) and at the long term follow-up (−0.40, −0.63 to −0.21, nine studies). Promotion of physical activity significantly reduced fatigue at all three time points: end of treatment (standardised mean difference −0.32, 95% CrI −0.62 to −0.01, seven studies), short term (−0.51, −0.84 to −0.17, one study), and long term (−0.52, −0.86 to −0.18, two studies). Self-management focusing on energy conservation was not significantly beneficial at the end of treatment (standardised mean difference −0.20, 95% CrI −0.52 to 0.12, 10 studies) or at the short term follow-up (−0.13, −0.51 to 0.25, seven studies) but at longer term follow-up, comparable benefit with other interventions was suggested (−0.42, −0.90 to 0.09, three studies). The standard deviation of the variation between studies in the end of treatment, short term, and long term network meta-analyses indicated moderate heterogeneity of studies in each of the analyses. No significant inconsistency was detected within the networks.

Conclusions Interventions that support individuals to increase physical activity or that are based on CBT were effective in reducing fatigue in people with long term medical conditions. The strength of the evidence was moderate to low. Although relatively few studies in any condition other than multiple sclerosis exist, the magnitude of effect seemed to be similar across different conditions.

What is already known on this topic​

• Fatigue is common in long term medical conditions
• Clinical trials in specific conditions suggest benefit from non-pharmacologic interventions for fatigue

What this study adds​

• Interventions that support individuals to increase physical activity or that are based on cognitive behavioural approaches were effective in reducing fatigue in people with long term medical conditions
• The strength of the evidence for these findings was moderate to low, with considerable heterogeneity between studies and within intervention categories

How this study might affect research, practice, or policy​

• Clinical services should find ways to offer these interventions to people with fatigue associated with long term conditions
• Research should evaluate the feasibility and effectiveness of providing interventions in a transdiagnostic way, rather than for individual medical conditions

 

[Dolphin]

We conducted a systematic review and network meta-analysis to investigate the clinical effectiveness of non-pharmacological interventions for fatigue in long term conditions. We chose to conduct a network meta-analysis to compare multiple interventions. The scope of the review reflects the specification of the funders in their call for commissioned research, which specifically excluded fatigue after cancer, fatigue after infection (including myalgic encephalomyelitis or chronic fatigue syndrome), and fatigue in conditions where the diagnosis relies only on symptoms. This evaluation of clinical effectiveness comprises one part of a larger evidence synthesis about interventions for fatigue in long term medical conditions: health economic30 and qualitative components (Booth, in press) are reported separately.

Population​

We included adults with a long term condition, based on the NHS definition as “an illness that cannot be cured but that can usually be controlled with medicines or other treatments.” The commissioning brief specifically excluded fatigue in people with cancer, in relation to or after infection (HIV, hepatitis C, long covid, and myalgic encephalomyelitis or chronic fatigue syndrome), or resulting from injuries or developmental disorders. Also excluded were conditions where symptoms, rather than observable pathology, were the defining features (eg, fibromyalgia or irritable bowel syndrome).
