ICU sedation, delirium & recovery
The trajectory of sleep after critical illness: a 24-month follow-up study
Authors' conclusion
Our findings reveal that a subset of critical illness survivors requires up to 24 months after the acute phase to fully restore their sleep quality, while a significant proportion does not experience a clinically significant improvement in sleep quality over this period.
Study context
- Population
- ICU survivors of SARS-CoV-2 infection69.9% males
- Participants
- 196 survivors
- Exposure
- Sleep quality trajectory groups: healthy vs minimal clinically important improvement (MCII) vs non-MCII
- Outcome
- Trajectory of sleep quality (PSQI score) from short-term assessment to 24 months after hospital discharge
- Follow-up
- Up to 24 months
Methodological details24-month follow-up
- 24-month follow-up
Main finding
As reported in the abstract
Change in PSQI score, short-term to 24-month follow-up (global population)
Mean change in PSQI score (95% CI - 1.50 to - 0.31) points
- 0.91
Observational data: associations, not effects.
Further findings
Mental health (HADS) and quality of life (SF-12 mental score)
- PSQI score trajectories closely aligned with those of the HADS and SF-12 mental scores
