Acute cardiac care & resuscitation
Observer-reported cognitive decline in out-of-hospital cardiac arrest survivors and its association with long-term survivor and relative outcomes
Authors' conclusion
Nearly half of OHCA survivors may suffer long-term cognitive decline. Worse self-reported mental and physical outcomes among survivors and their relatives are associated with potential cognitive decline
Study context
- Population
- Adult out-of-hospital cardiac arrest (OHCA) survivors (2016–2019) and their relatives, Denmark (DANish Cardiac Arrest Survivorship survey)
- Outcome
- Observer-reported cognitive decline (IQCODE-CA, completed by relatives)
Methodological detailsnational survey
- National survey
