Hypothesis
Older ICU survivors experience fragmented sleep architecture after discharge.
Conclusion
Older ICU survivors have significantly lower percentages of important sleep stages compared to healthy older adults.
Supporting Evidence
- Participants were awake approximately 53.4% of nighttime hours.
- The median percentage of stage N1 sleep was 2.1%.
- The median percentage of stage N2 sleep was 26.35%.
- The median percentage of stage N3 sleep was 0.8%.
- The median percentage of REM sleep was 0.15%.
- All sleep stages were significantly lower than expected reference values.
Takeaway
Older people who leave the ICU often have trouble sleeping well, which is important for getting better.
Methodology
Sleep architecture was measured using portable polysomnography over two nights.
Participant Demographics
Older ICU survivors who were functionally independent before hospitalization.
