Prediction of Outcome in Moderate and Severe Traumatic Brain Injury: The Value of Pragmatic Estimation of the Duration of Posttraumatic Confusional State.

PMID 40980529WHAT IT FOUND
Longer posttraumatic confusion predicted worse 12-month recovery, especially in severe TBI.
Patients with confusion lasting 7 days or less had high rates of good recovery (78% moderate, 71% severe). Confusion lasting more than 28 days strongly predicted severe disability or death.
Key findings
01In severe TBI, duration of posttraumatic confusional state (PTCS) was the only significant predictor of worse outcome in multivariable models, outperforming admission GCS and CT findings.
02Almost all patients with PTCS duration of 28 days or less achieved independence in daily life (GOSE score 5-8) at 12 months, with negative predictive values of 96% for moderate TBI and 99% for severe TBI.
03When PTCS lasted 0-7 days, good recovery (GOSE 7-8) was observed in 78% of moderate TBI cases and 71% of severe TBI cases.

What it does not show
PTCS duration was often estimated retrospectively from medical records, which may be less accurate than prospective assessment. The duration was categorized into weekly intervals, losing fine-grained temporal data. The study was conducted at a single regional neurosurgical center, so results may not generalize to patients treated solely in general hospitals. Some patients had unknown PTCS duration due to missing records or transfer outside the health region. Factors such as sedation, analgesics, or acute stress may have influenced the assessment of confusion, potentially confounding the PTCS duration.

The easy way to misread this
Do not assume that admission GCS or CT findings are the best predictors of long-term functional outcome in severe TBI. This study found that when the duration of posttraumatic confusion was included in the models, GCS and CT scores were no longer significant predictors of outcome. The clinical course of confusion is a more powerful prognostic tool than the initial injury snapshot.
