Temporal Evolution and Outcomes of Non-Traumatic Intracerebral Hemorrhage in Hospitalized Patients.

OBJECTIVE: To investigate the radiographic features, temporal evolution, and outcome of patients who develop non-traumatic intracerebral hemorrhage (ICH) while hospitalized for other causes. METHODS: We retrospectively reviewed consecutive Emergency Department ICH (ED-ICH) and in-hospital ICH (IH-ICH) over an 8-year period. Variables including demographics, medical history, lab values, lead time to diagnosis, defined as time from last known well to first CT scan, and clinical characteristics, follow-up CT scan, as well as the frequency of withdrawal of life support were compared in the two groups. Mortality in correlation with ICH score was assessed. RESULTS: Sixty-One IH-ICH and 216 ED-ICH patients were compared. History of cardiac disease, cancer, coagulopathy and higher SOFA score at time of diagnosis were significantly higher in the IH-ICH group (all P< 0.01). Time from symptom onset to diagnosis was shorter in the IH-ICH group (median 95 versus 117 minutes, P=0.011). Thirty six percent of IH-ICH fell into a worse ICH category when recalculated 6 hours from initial scan time, compared to only 10% of the ED-ICH. ICH score was well calibrated in ED-ICH when assessed both at diagnosis and 6 hours later, but underestimated actual mortality in the IH-ICH, particularly at ICH scores 0 to 3. End of life measures were pursued in 69% of IH-ICH group compared to 19% in the ED-ICH group. CONCLUSIONS: IH-ICH, is associated with higher overall mortality rates and often times heralds withdrawal of life sustaining therapies in patients. In addition, IH-ICH in comparison to ED-ICH, significantly changes in severity metrics within the first 6 hours. ICH score is not accurate and not calibrated to reflect reasonable stratification of mortality in IH-ICH. Prospective validation and investigation of variables accounting for higher IH-ICH mortality are needed.

Hemicraniectomy and durotomy upon deterioration from infarction-related swelling trial: randomized pilot clinical trial.

BACKGROUND AND PURPOSE: Hemicraniectomy and Durotomy Upon Deterioration From Infarction-Related Swelling Trial (HeADDFIRST) was a randomized pilot study to obtain information necessary to design a Phase III trial to evaluate the benefit of surgical decompression for brain swelling from large supratentorial cerebral hemispheric infarction. METHODS: All patients with stroke were screened for eligibility (age 18-75 years, National Institutes of Health Stroke Scale≥18 with Item 1a<2 [responsive to minor stimulation], and CT demonstrating unilateral, complete middle cerebral artery territory infarction by specific imaging criteria). All enrolled patients were treated using a standardized medical treatment protocol. Those with both≥4 mm of pineal shift and deterioration in level of arousal or ≥7.5 mm of anteroseptal shift within 96 hours of stroke onset were randomized to continued medical treatment only or medical treatment plus surgery. Death at 21 days was the primary outcome measure. RESULTS: Among 4909 screened patients, only 66 (1.3%) patients were eligible for HeADDFIRST. Forty patients were enrolled, and 26 patients developed the requisite brain swelling for randomization. All who failed to meet randomization criteria were alive at 21 days. Mortality at 21 and 180 days was 40% (4/10) in the medical treatment only and 21% (3/14) and 36% (5/14) in the medical treatment plus surgery arms, respectively. CONCLUSIONS: HeADDFIRST randomization criteria effectively distinguished low from high risk of death from large supratentorial cerebral hemispheric infarction. Lower mortality in the medical treatment only group than in other published trials suggests a possible benefit to standardizing medical management. These results can inform the interpretation of recently completed European trials concerning patient selection and medical management. CLINICAL TRIAL REGISTRATION: This trial was not registered because enrollment began before July 1, 2005.
