AimsTo (1) describe the prevalence of cognitive dysfunctions using performance-based and reported measures, and (2) explore the correlations between selected performance-based, patient-reported, and observer-reported neurocognitive outcome measures three months after hospital discharge in a population of out-of-hospital cardiac arrest (OHCA) survivors.MethodsData from 193 OHCA survivors was derived from the Danish multicenter REVIVAL cohort study. At three months, four subtests of the performance-based Delis-Kaplan Executive Function System (D-KEFS) (Trail making, Color-word interference, Verbal fluency, and Figure design), the patient-reported Behavior Rating Inventory of Executive Function - Adult (BRIEF-A), and the observer-reported 16-item Short Form (SF) Informant Questionnaire on Cognitive Decline after Cardiac Arrest (SF-16 IQCODE-CA) were collected. Spearman's rank coefficient correlation analysis was performed to examine correlations between D-KEFS, BRIEF-A, and SF-16 IQCODE-CA.ResultsOverall, 21% of survivors exhibited impairment in executive functioning using the D-KEFS subtest Color-word interference, while only 9% self-reported executive impairment (BRIEF-A) and 7% of relatives reported cognitive decline (SF-16 IQCODE-CA) in survivors at three months post-arrest. All correlations between D-KEFS, BRIEF-A and SF-16 IQCODE-CA were negligible to low.ConclusionThe results of this REVIVAL substudy suggest that although the performance-based and reported measures did not correlate, dual neurocognitive screening tools containing both a self-reported and an informant-reported version may have the potential to detect executive discrepancies in the return to everyday life and guide targeted neurorehabilitation after OHCA.Copyright © 2024 The Author(s).
