Prognostic scores help in predicting mortality and functional outcome post intracerebral hemorrhage (ICH). We aimed to validate the ICH and ICH-GS scores in a cohort of Indian patients with ICH and observe the impact of any surgical intervention on prognostication. This was an ambispective observational study of primary ICH cases enrolled between January 2014 and April 2018. Observed mortality on ICH and ICH GS scores for the entire cohort and individually for the medically and surgically managed patients was compared to the published mortality in the original derivation cohorts. 617 patients, (464 retrospective and 153 prospective) of ICH were included. In hospital mortality and 30-day mortality was 28.7% and 28.5% respectively. There was a significant association of increasing mortality with increasing ICH and ICH-GS scores. Area under receiver operating characteristic curve for 30-day mortality was 75.9% and 74.1% for ICH and ICH-GS scores respectively. However, mortality observed at individual scores was significantly less than previously reported. Among the surgically intervened patients (n = 265), both the expected mortality at baseline and discriminative ability of ICH and ICH-GS scores for 30-day mortality was significantly reduced following surgical intervention (ROC in surgically intervened groups: 59.9 (52.6-67.2) and 63(56-70) for ICH and ICH-GS scores respectively). Although ICH and ICH-GS scores are valid in Indian population, mortality at individual scores is lower than previously reported. Mortality prediction using ICH and ICH GS scores is significantly modified by surgical interventions. Thus, newer prognostic tools which incorporate surgical intervention need to be developed and validated in future.
