The epidemiology of motorcycle-related acute traumatic brain injury: The NOMADEN study.

BACKGROUND

Although persisting to be a public health hazard in Indonesia, motorcycle-related traumatic brain injury (TBI) due to road traffic accidents (RTA) lacks comprehensive national data. We aim to study the epidemiological pattern of motorcycle-related TBI and analyze the determinants related to mortality in the only neurosurgical center in the rural province of North Maluku, Indonesia.

METHODS

Using the North Maluku Database in Neurosurgery register, information regarding age, sex, health insurance, alcohol use, point of referral, degree of severity, brain computed tomography abnormalities, helmet use, surgery, injury-to-admission time (IAT), and relationship to the motorcycle were obtained from patients admitted to Chasan Boesoirie General Hospital, Ternate, in 2021-2022. Multivariable logistic regression analysis was performed to investigate associations with in-hospital mortality.

RESULTS

Of all RTA-related TBI patients (n = 353), 91.8% (n = 324) were caused by motorcycle collision (mean age ± standard deviation of 30.5 ± 16.7 years old). The majority were motorcyclists (66.7%), male (64.8%), IAT >4 h (55.9%), financed by non-Jaminan Kesehatan Nasional mechanism (66.4%), not under alcohol influence (78.4%), referred from Ternate (55.2%), and suffered mild TBI (75%). Thirty patients (9.3%) succumbed to death. Moreover, 9.3% and 91.2% were ≤17 years old and helmetless. Glasgow coma scale and IAT were significantly associated with in-hospital mortality (odds ratio [95% confidence interval]: 0.58 [0.49-0.68] and 5.44 [1.00-30.34], respectively).

CONCLUSION

The young and productive males dominated the motorcycle-related TBI patients in North Maluku. Poor compliance with road traffic laws, as demonstrated by a considerable proportion of underage, alcohol-intoxicated, and helmetless patients, necessitated prompt actions from all related elements.
