Background: : The standardized mortality ratio (SMR) of epilepsy in Asia ranges from 2.5 to 5.1. However, there are no such published data in Malaysia to date. Understanding the mortality rate and related factors will allow us to better assess and monitor the health status of PWE, thereby, preventing premature deaths among PWE. Hence, this study aimed to determine the mortality rate of adults with epilepsy (PWE) at the University Malaya Medical Centre (UMMC), a tertiary hospital in Malaysia. Method: : A total of 2218 PWE were recruited retrospectively into this study. Deceased cases from 2009-2018 were identified from the National Registry Department of Malaysia. Age-, gender-, and ethnic-specific SMR were calculated. Result: : There was a total of 163 deaths, of which 111 (68.1%) were male. The overall case-fatality rate (CFR) was 7.3%. Male PWE had higher CFR (9.2%) compared to females (5.1%, p<0.001). The annual death rate of PWE was 867 per 100, 000 persons. The overall all-cause SMR was 1.6 (CI 95% 1.3-1.8). The SMR for younger age groups (15-19 and 20-29 years) were higher (5.4-5.5) compared to other age groups (0.4-2.5). Overall SMR for male PWE (1.8, 95% CI 1.5-2.1) was higher than females (1.2, 95% CI 0.9-1.6). However, the SMR for female PWE in the younger age groups (15-19, 20-29 and 30-39 years) was higher. SMR among the Indian PWE was the highest (1.6, 95% CI 1.2-2.0) compared to the Chinese (1.5, 95% CI 1.2-1.9) and the Malays (1.4, 95% 1.0-1.9). The CFR was higher in those with focal epilepsy (8.5% vs. 2.5-3.7% in genetic and other generalized epilepsies, p=0.003), epilepsy with structural cause (9.5% vs. 5.9% in others, p=0.005) and uncontrolled seizures (7.9% vs. 5.2% in seizure-free group, p<0.001). Conclusion: : The mortality rate of PWE in Malaysia is higher than that of the general population but lower compared to other Asian countries. Specifically, the rates are higher in the younger age group, male gender, and Indian ethnicity. Those with focal epilepsy, structural causes and uncontrolled seizures have higher mortality rates.
