Abstract

Background: Outcome from spontaneous intracerebral hemorrhage (sICH) may depend on patient-care variability. We developed as ICH-specific therapy intensity level (TIL) metric using evidence-based elements in a high severity sICH cohort. Methods: This is a cohort study of 170 patients with sICH and any intraventricular hemorrhage treated in 2 academic neuroICUs. Pre-defined quality indicators were identified based on current guidelines, scientific evidence, and likelihood of care documentation in first 72 h of hospital admission. We assessed performance on each indicator and association with discharge mortality. Significant indicators were aggregated to develop a TIL score. The predictive validity of the best fit TIL score was tested with threefold cross-validation of multivariate logistic regression models of in-hospital survival and good outcome (modified Rankin score 0–3). Results: Median ICH score was 3; discharge mortality was 51.2 %. Five/19 tested variables were significantly associated with lower discharge mortality: no DNR/withdrawal of treatment within 24 h of admission, target glucose within 4 h of high glucose, no recurrent hyperpyrexia, clinical reversal of herniation/intracranial pressure >20 mmHg within 60 min of detection, and reversal of INR (<1.4) within 2 h of first elevation. One point was given for each or if not applicable. Median TIL score was significantly higher in survivors versus non-survivors (5[1] vs. 3[1]; P < 0.001). A 4-point aggregated TIL score was most predictive of discharge survival (area under receiving operating characteristic curve 0.85, 95 % CI 0.80–0.90) and good outcome (AUC 0.84) and was an independent predictor of both (survival: OR 7.10; 95 % CI 3.57–14.11; P < 0.001; good outcome: OR 3.10; 95 % CI 1.06–8.79; P < 0.001). Conclusion: A simplified TIL score using evidenced-based patient-care parameters within first 3 days of admission after sICH was significantly associated with early mortality and good outcome. The next step is prospective validation of the simplified TIL score in a large clinical trial.
