What This Means
This research compared the accuracy of three scoring systems used to predict outcomes for patients who have had a spontaneous brain bleed (intracerebral haemorrhage, or ICH) — specifically, whether patients would survive, have a good functional recovery, or be severely disabled or die by the time they left the hospital. The three tools studied were the ICH Score, max-ICH, and the ICH Functional Outcome Score (ICH-FOS). Data came from over 8,400 patients across 56 countries, making this one of the largest and most geographically diverse validation studies of these tools to date.
All three scoring systems performed reasonably well to excellently at predicting hospital discharge outcomes, but they were not equally accurate. The ICH-FOS consistently outperformed the other two scores across every outcome measured — death, severe disability, and a combined measure of the two. The ICH Score, the oldest and simplest tool, showed particularly weaker performance when predicting functional disability (as opposed to death alone). The max-ICH score, which relies only on information routinely collected at the bedside, performed nearly as well as ICH-FOS and was highlighted as a practical alternative for clinical settings.
This research suggests that clinicians and health systems using older or simpler ICH prognostic tools may benefit from adopting more comprehensive scoring systems like ICH-FOS, especially when making decisions about functional recovery. At the same time, the finding that max-ICH performs robustly using only routinely available data points makes it an attractive option in resource-limited settings. The multinational nature of this study increases confidence that these findings are broadly applicable across different healthcare contexts worldwide.
