Motor Vehicle Accidents(MVA) are the main attendees of accident emergency unit in UMMC. Assessment by doctor found that some ot them used alcohol/substance prior to MVA event. They also found to have abnormal sleep pattern and “emotional problems” that contribute to MVA and injuries. Yet, limited study available in Malaysia that explore the relationship between sleep disorders, substance use, psychiatric morbidity and MVA events.

To investigate the prevalence and associations of sleep disoders, substance use and psychiatric comorbidity among attendees in accident emergency unit, UMMC.

This is a cross-sectional hospital based study that examine all MVA attendees age 18 and above with written consent in accident emergency unit UMMC from 30 September to 30 November 2011. We exclude those patients with Glasgow Coma Sale(GCS) less than 10, intoxication and refused consent. We measure sleep disorders using Epsworth Sleep Scale(ESS), Psychiatric morbidity using Hospital Anxiety Depresion Scale(HADS) and substance use with Drug abuse screening tool(DAST). We also do rapid urine test kits for opiates, canabis, amphetamine type stimulants(ATS) and benzodiazepines. Chi square test will be analyses for the variable asssociations using SPSS 16.

We expect that the prevalence of sleep disorders, subsatnce use and other psychiaric comorbidity are higher among MVA attendees. There are some association in between those factors that contributes to the MVA events.

MVA attendees probably need further assesment as routine e.g. sleep study, psychiatric morbidity and drug screening in order to better manage them and prevent further MVA in the future.
