Comparison of Conventional Intensive Care Scoring Systems and Prognostic Scores Specific for Intracerebral Hemorrhage in Predicting One-Year Mortality.

ABSTRACT: BACKGROUND:Specific prognostic models for intracerebral hemorrhage (ICH) have short and simple features, whereas intensive care unit (ICU) severity scales include more complicated parameters. Even though newly developed ICU severity scales have disease-specific properties, they still lack radiologic parameters, which is crucial for ICH. AIMS:To compare the performance of the Simplified Acute Physiology Score (SAPS) III, Acute Physiology and Chronic Health Evaluation (APACHE) IV, Logistic Organ Dysfunction Score (LODS), ICH, max-ICH, ICH functional outcome score (ICH-FOS), and Essen-ICH for prediction of in-hospital and one-year mortality of patients with ICH. METHODS:A single-center analysis of 137 patients with ICH was conducted over 5 years. The performance of scoring systems was evaluated with receiver operating characteristic analysis. The independent predictors of one-year mortality were investigated with a multivariate logistic regression analysis. The SAPS-III score was calculated both in the emergency department (ED) and ICU. RESULTS:Among the independent variables, the need for mechanical ventilation, hematoma volume, the presence of intraventricular hemorrhage, and hematoma originating from both lobar and nonlobar regions were found as the strongest predictor of one-year mortality. For in-hospital mortality, the discriminative power of SAPS-II, APACHE-IV, and LODS was excellent, and for SAPS-III-ICU and SAPS-III-ED, it was good. For one-year mortality, the discriminative power of SAPS-II, APACHE-IV, LODS, and SAPS-III-ICU was good, and for SAPS-III-ED, Essen-ICH, ICH, max-ICH, and ICH-FOS, it was fair. CONCLUSIONS:Although all three ICH-specific prognostic scales performed satisfactory results for predicting one-year mortality, the common intensive care severity scoring showed better performance. SAPS-III scores may be recommended for use in EDs after proper customization.

Project description:IntroductionSpontaneous intracerebral hemorrhage (ICH) is one of leading causes of mortality and morbidity worldwide. Several predictive models have been developed for ICH; however, none of them have been consistently used in routine clinical practice or clinical research. In the study, we aimed to develop and validate a risk score for predicting 1-year functional outcome after ICH (ICH Functional Outcome Score, ICH-FOS). Furthermore, we compared discrimination of the ICH-FOS and 8 existing ICH scores with regard to 30-day, 3-month, 6-month, and 1-year functional outcome and mortality after ICH.MethodsThe ICH-FOS was developed based on the China National Stroke Registry, in which eligible patients were randomly divided into derivation (60%) and validation (40%) cohorts. Poor functional outcome was defined as modified Rankin Scale score (mRS) ≥3 at 1 year after ICH. Multivariable logistic regression was performed to determine independent predictors, and β-coefficients were used to generate scoring system of the ICH-FOS. The area under the receiver operating characteristic curve (AUROC) and Hosmer-Lemeshow goodness-of-fit test were used to assess model discrimination and calibration.ResultsThe overall 1-year poor functional outcome (mRS ≥ 3) was 46.7% and 44.9% in the derivation (n = 1,953) and validation (n = 1,302) cohorts, respectively. A 16-point ICH-FOS was developed from the set of independent predictors of 1-year poor functional outcome after ICH including age (P < 0.001), admission National Institutes of Health Stroke Scale score (P < 0.001), Glasgow Coma Scale score (P < 0.001), blood glucose (P = 0.002), ICH location (P < 0.001), hematoma volume (P < 0.001), and intraventricular extension (P < 0.001). The ICH-FOS showed good discrimination (AUROC) in the derivation (0.836, 95% CI: 0.819-0.854) and validation (0.830, 95% CI: 0.808-0.852) cohorts. The ICH-FOS was well calibrated (Hosmer-Lemeshow test) in the derivation (P = 0.42) and validation (P = 0.39) cohort. When compared to 8 prior ICH scores, the ICH-FOS showed significantly better discrimination with regard to 1-year functional outcome and mortality after ICH (all P < 0.0001). Meanwhile, the ICH-FOS also demonstrated either comparable or significantly better discrimination for poor functional outcome and mortality at 30-day, 3-month, and 6-month after ICH.ConclusionThe ICH-FOS is a valid clinical grading scale for 1-year functional outcome after ICH. Further validation of the ICH-FOS in different populations is needed.

Project description:Background and Purpose- It is unknown whether blood pressure (BP) reduction influences secondary brain injury in spontaneous intracerebral hemorrhage (ICH). We tested the hypothesis that intensive BP reduction is associated with decreased perihematomal edema expansion rate (PHER) in deep ICH. Methods- We performed an exploratory analysis of the ATACH-2 randomized trial (Antihypertensive Treatment of Acute Cerebral Hemorrhage-2). Patients with deep, supratentorial ICH were included. PHER was calculated as the difference in perihematomal edema volume between baseline and 24-hour computed tomography scans divided by hours between scans. We used regression analyses to determine whether intensive BP reduction was associated with PHER and if PHER was associated with poor outcome (3-month modified Rankin Scale score 4-6). We then used interaction analyses to test whether specific deep location (basal ganglia versus thalamus) modified these associations. Results- Among 1000 patients enrolled in ATACH-2, 870 (87%) had supratentorial, deep ICH. Of these, 780 (90%) had neuroimaging data (336 thalamic and 444 basal ganglia hemorrhages). Baseline characteristics of the treatment groups remained balanced (P>0.2). Intensive BP reduction was associated with a decrease in PHER in univariable (β= -0.15; 95% CI, -0.26 to -0.05; P=0.007) and multivariable (β=-0.12; 95% CI, -0.21 to -0.02; P=0.03) analyses. PHER was not independently associated with outcome in all deep ICH (odds ratio, 1.14; 95% CI, 0.93-1.41; P=0.20), but this association was modified by the specific deep location involved (multivariable interaction P=0.02); in adjusted analyses, PHER was associated with poor outcome in basal ganglia (odds ratio, 1.42; 1.05-1.97; P=0.03) but not thalamic (odds ratio, 1.02; 95% CI, 0.74-1.40; P=0.89) ICH. Conclusions- Intensive BP reduction was associated with decreased 24-hour PHER in deep ICH. PHER was not independently associated with outcome in all deep ICH but was associated with poor outcome in basal ganglia ICH. PHER may be a clinically relevant end point for clinical trials in basal ganglia ICH.
