    Long COVID, or post-acute COVID-19 sequelae, is experienced by an estimated one in eight adults following acute COVID-19. Long COVID is a new and complex chronic health condition that typically includes multiple symptoms that cross organ systems and fluctuate over time; a one-size-fits-all approach is, therefore, not likely to be appropriate nor relevant for long COVID treatment. ‘Treatable Traits’ is a personalized medicine approach, purpose-built to address the complexity and heterogeneity of complex chronic conditions.

    This comprehensive review aimed to understand how a treatable traits approach could be applied to long COVID, by first identifying the most prevalent long COVID treatable traits and then the available evidence for strategies to target these traits. An umbrella review of 22 systematic reviews identified 34 symptoms and complications common with long COVID, grouped into eight long COVID treatable trait clusters: neurological, chest, psychological, pain, fatigue, sleep impairment, functional impairment and other.

    A systematic review of randomized control trials identified 18 studies that explored different intervention approaches for long COVID prevention (k = 4) or management (k = 14). While a single study reported metformin as effective for long COVID prevention, the findings need to be replicated and consensus is required around how to define long COVID as a clinical trial endpoint. For long COVID management, current evidence supports exercise training or respiratory muscle training for long COVID treatable traits in the chest and functional limitation clusters.

    While there are studies exploring interventions targeting other long COVID treatable traits, further high-quality RCTs are needed, particularly targeting treatable traits in the clusters of fatigue, psychological, pain and sleep impairment.

    Does anyone else find the choice of the word 'trait' rather odd here?
    * a distinguishing quality or characteristic, typically one belonging to a person.
    Similar: characteristic, attribute, feature, quality, essential quality, property, distinction, idiosyncrasy, peculiarity, quirk, foible, singularity, oddity, eccentricity, abnormality, mark, trademark, hallmark, earmark, mannerism, ..habit, tendency
    * a genetically determined characteristic.

    The word makes it sound as though the fatigue or functional limitation is something intrinsic to the person, rather than a symptom that is a consequence of a disease.

    The authors are from a Centre of Excellence - Treatable Traits, a consortium of people involved in respiratory medicine.
    I can see what they are doing, and it makes some sense e.g. is the failure of the treatment approach due to the poor adherence or the inhaler technique of the person? But I find the approach rather questionable in the context of Long covid where the 'treatments' don't count for much.

    I can't think more, so will just post this and hope it makes sense.
