Intracerebral hemorrhage in Intensive Care Unit: early prognostication fallacies. A single center retrospective study.

BACKGROUND: Intracerebral hemorrhage (ICH) admitted to Intensive Care is deem of poor prognosis. The aim of this study was to compare observed and predicted 30-day mortality and to evaluate long term functional outcome in a consecutive ICH cohort.

METHODS: Retrospective analysis of prospectively collected data of ICH patients managed in a Neuro-ICU from 2012 to 2015.

RESULTS: Out of 136 consecutive patients, 34 (25%) had "withholding of life-sustaining treatment" (WLST) order and 102 (75%) received a "full treatment" (FT). WLST cohort: median (IQR): 72 (70-77) years old, Glasgow Coma Scale (GCS) 4 (3-4) at admission, ICH volume 114 cm3 (68-152); all patients died during neuro-ICU recovery, 28 (82%) patients had brain death diagnosis and 15 (54%) of these were organ donors. FT cohort: 67 (51-73) years old, GCS 9 (6-12) at admission, ICH volume 46 (24-90) cm3, neurosurgery for clot removal in 65 (64%) (P<0.05 vs. WLST cohort for each of previously listed variables); 13 (13%) patients died during neuro-ICU recovery, of these 11 (85%) patients had brain death diagnosis and 4 (36%) of them were organ donors. Overall 30-day observed mortality for FT group was 18% (95% CI: 11-26%). Patients with ICH Score 1, 2, 3, 4+ had 0%, 10%, 16% and 26% 30-day mortality, respectively (P<0.01 vs. ICH Score). Full treatment group 180-day mortality was 32% (95% CI: 24-42%). Modified Rankin Scale (mRS) after one year was ≤3 in 35 (35%), i.e. good recovery, and >3 in 64 (65%). Neurosurgery for clot removal was associated with a lower 30 and 180-day mortality (P=0.01 and P=0.03, respectively) and along with GCS at admission it was an independent significant prognostic factor.

CONCLUSIONS: Mortality and functional outcome is less severe than predicted in patients with ICH receiving a full medical and/or surgical treatment.
