Structured diagnostic strategies for psychological problems in cardiac arrest survivors: an important knowledge gap.

Psychological and cognitive problems frequently persist after cardiac arrest, even among survivors with favourable neurological recovery. We systematically reviewed whether structured approaches to the identification and assessment of psychological, emotional or cognitive sequelae improve patient- or key supporter-relevant outcomes. MEDLINE, Embase and CENTRAL were searched from inception to December 2025. Among 1605 records, none met the prespecified eligibility criteria. The absence of eligible comparative evidence precludes evidence-based recommendations regarding which instruments, thresholds, timing or multidisciplinary pathways should be used. Pragmatic comparative studies should urgently test reproducible screening-to-care pathways against usual care, incorporating diagnostic confirmation, referral, treatment access and survivor-centred outcomes.
