Highlights
  • Sleep disturbances are highly prevalent in long COVID-19 patients.
  • Sleep disturbances include poor sleep quality, insomnia and excessive daytime sleepiness.
  • It is impossible to know whether sleep problems pre-dated COVID-19 infection.
  • The healthcare sector should provide early, effective treatment.

Abstract

Objective
We aimed to study the prevalence of sleep disturbances in patients with long COVID-19.

Methods
We conducted a systematic review and meta-analysis of the pooled prevalence of sleep disturbances in patients post COVID-19. We systematically searched relevant studies from three databases, including Medline, Embase and Scopus. Original articles were included based on specific criteria: peer-reviewed, observational studies involving adults (18 or older) with confirmed post COVID-19 status through PCR testing and focused on sleep in the context of post COVID-19. Exclusion criteria included non-English articles, studies with insufficient data, and narrative/systematic reviews. The search was performed from 31st July 2023 to 15th August 2023. We identified 35 eligible papers; however, we excluded 6 studies which did not describe the sleep assessment. We used a random-effects meta-analysis model to estimate the pooled prevalence of sleep disturbances.

Results
29 studies involved 13,935 long COVID-19 patients; approximately 39% of participants were male aged 18 to 97 years. The overall pooled prevalence of sleep disturbance was 46% (95% CI: 38–54%). Subgroup analyses revealed that the pooled prevalence of poor sleep quality was 56% (95% CI: 47–65%). The pooled prevalence of insomnia was 38% (95% CI: 28–48%). Finally, the pooled prevalence of excessive daytime sleepiness was 14% (95% CI: 0–29%).

Conclusion
Sleep disturbances are common in long COVID-19 patients. The healthcare sector should recognise these sleep issues and provide an early, effective treatment to prevent long-term sequelae of sleep problems.

Well that's obviously incorrect. You ask, you get answers, this is as simple as that. Not only is it possible, it's even above trivial to the point of being expected. If 29 studies didn't ask you have very deep fundamental issues with the entire discipline doing research on this, but I doubt very much that they didn't ask.

Again, what a terrible way to do research. Evidence-based medicine is such trash, overly expensive while being unable to do the most basic stuff right.

Well you don't have any, in part because most of the effort is just mediocre like this. If my mother had wheels and an engine, she'd be a car.

Indeed. That statement is coming from a woman who invented a scale asking people whether a symptom now is worse or better than what it was when they were well. If it really is impossible to know whether sleep problems pre-dated infection, then it is also impossible to know, simply by asking people, whether fatigue problems pre-dated infection or how current fatigue levels relate to pre-infection levels.

A product looking for a market … sorry pretend ‘solution’ looking to reframe a problem to claim it will ‘help’

same old gravy train ?

Perhaps this contradiction is worth highlighting in a letter to the editor.
