Incidence and prognostic impact of delirium after cardiac arrest: a systematic review and meta-analysis.

ABSTRACT:

Background

Delirium is common after ROSC, yet reported incidence varies widely across studies that differ in instruments, assessment windows, and post-arrest care. We aimed to quantify the incidence of delirium among adult post-ROSC ICU survivors and evaluate its association with short-term mortality.

Methods

The review was reported according to PRISMA guidelines and registered on PROSPERO (CRD420251160097). PubMed, Embase, Scopus, and Web of Science were searched from 2000 to 30 Sep 2025 without language restrictions. Eligible studies enrolled adults (≥18 years) with ROSC admitted to ICU and reported ICU-period delirium using validated tools (CAM-ICU, ICDSC, DSM-based diagnosis) or structured screening scales. Proportions were pooled on the logit scale using random-effects
