ICU sedation, delirium & recovery
Cognitive Functioning After Circulatory Shock: A Prospective Observational Study
Authors' conclusion
We found cognitive impairment in more than three out of four ICU survivors immediately after ICU treatment for circulatory shock. We observed an improvement in cognitive functioning between ICU discharge and 3 months follow-up.
Study context
- Population
- Adult intensive care unit (ICU) survivors of circulatory shock, Helsinki University Hospital ICU36 completed 3-month follow-up
- Participants

- Outcome
- Cognitive functioning (Montreal Cognitive Assessment (MoCA) test; cognitive impairment = MoCA score < 26 points)
- Follow-up

Main finding
As reported in the abstract
MoCA score and prevalence of cognitive impairment
| Outcome | Controls |
|---|---|
| MoCA score and prevalence of cognitive impairment | median 27 (IQR 25–28) points |
| Prevalence of cognitive impairment | 33% |
- Patients (3 months) vs Patients (at discharge): P < 0.001 — improvement from discharge to follow-up
Observational data: associations, not effects.
