We evaluated the prognostic value of early ICP trajectories.\u003Cbr>Methods: We formed a multicenter ICU cohort from MIMIC-IV (2008–2022), eICU (2014–2015), and NSICU (2024–2025) . Latent class growth modeling identified ICP trajectories over the first 120 h. Associations with in-hospital mortality were tested with Cox models, and incremental value beyond baseline clinical variables was quantified by AUC, integrated discrimination improvement (IDI), and net reclassification improvement (NRI) . Sensitivity analyses were performed across datasets and age groups.\u003Cbr>Results: Among 1700 patients with ABI, four trajectories emerged—Severe Progressive, Stabilized Elevated, Mildly Elevated Stable, and Normal. Versus Normal, mortality risk was highest for Severe Progressive (HR 13.54; 95% CI 9.35–19.59), followed by Stabilized Elevated (HR 2.53; 1.83–3.49) and Mildly Elevated Stable (HR 1.48; 1.16–1.91) . In patients aged ≥55years, risk with Stabilized Elevated was amplified (HR 2.87; 1.97–4.20). Adding trajectories improved risk stratification (IDI +0.065; NRI +0.201) with modest AUC gains.\u003Cbr>Conclusions: Early ICP trajectories define reproducible phenotypes with distinct mortality risk. Incorporating trajectories—particularly the stabilized-elevated pattern in older adults—adds prognostic value beyond clinical variables and supports prospective validation. |  |\n| 1 | Introduction | injury (TBI), intracerebral hemorrhage (ICH), and ischemic |\n| Intracranial pressure (ICP) elevation frequently occurs in patients with acute brain injury (ABI), including traumatic brain | stroke [1, 2] .
