ICU sedation, delirium & recovery
Subjective sleep assessment compared to polysomnography in mechanically ventilated critically ill intensive care unit (ICU) patients
Authors' conclusion
In mechanically ventilated critically ill ICU patients, the level of agreement between SSA and PSG was low, and there was a significant overestimation of mean TST.
Study context

Main finding
As reported in the abstract
Agreement between SSA and PSG
- Level of agreement between subjective sleep assessment (SSA) and PSG was low
Observational data: associations, not effects.

P = 0.05
TST, sedated with dexmedetomidine (subgroup)
P = 0.56
TST, placebo or non-sedation (subgroup)
P = 0.17
