Background: Acute non-traumatic coma is a common problem in pediatric practice accounting for 10-15% of all hospital admissions and is associated with significant mortality. Assessment of the severity of coma is essential to comment on the likelihood of survival in comatose children. In the last three decades, various scores have been used to assess the severity of coma and to predict its outcome. Glasgow Coma Scale (MGCS) in spite of its various drawbacks has been widely used for assessing pediatric coma, though only few studies are available to support its use in pediatric coma as a whole. Hence the study was undertaken to evaluate the usefulness of coma scale in prediction of mortality in children between 1-12 years old admitted with coma of non-traumatic origin. Methods: A prospective study was conducted at Inpatient services of intensive medical care unit and general medical wards of Institute of child Health and Hospital for children, Egmore, Chennai, between October 2018 to November 2019. A Study Population consisting of children in the age group 1-12 years admitted in intensive care unit and medical wards with alteration in sensorium as one of the predominant complaints and admitted within 7 days of onset of coma were included. Sample size was 148. Chi-square test was used to study the association between the scores at Various times points and outcome. Results: It was observed that when the scores were between 3‐ 5 mortality rate was 67.0%, it was 17% when the minimal observed score was between 6-8. The group in which the minimal score never decreased be1ow 9 had no mortality. As the score increases the proportion of death decreases and the proportion having good recovery increases and vice versa. This type of association has been observed at different time points (Initial, 24 hrs, 48 hrs and 72 hrs). The significance of this association increases with the progression of time since admission. P value for the degree of association at various time points are: At presentation P < 0.00001, 24hrs - P < 0.000001, 48 hrs - P < 0.000001 and 72 hrs P < 0.00000001. Conclusion: There is highly statistically significant association between the GSC score levels and outcome. As the score increases the proportion of death decreases and the proportion having good recovery increases and vice versa.
