Post traumatic stress disorder among motor vehicle accident survivors attending the orthopaedic and trauma clinic at Kenyatta National Hospital, Nairobi.

OBJECTIVES To determine the prevalence rate of post traumatic stress disorder (PTSD) and associated risk factors among motor vehicle accident (MVA) survivors attending the orthopaedic and trauma clinic at Kenyatta National Hospital, Nairobi. DESIGN A cross-sectional study. SETTING Kenyatta National Hospital, Nairobi. SUBJECTS One hundred and ninety seven adult males and sixty seven female patients. METHOD The 264 patients were interviewed using a questionnaire to collect the socio-demographic data, the Self Rating Questionnaire (SRQ) and the Impact of Event Scale-Revised (IES-R). Diagnosis was made using the Diagnostic and Statistical Manual (DSM-IV). RESULTS The mean age was 34.63+/-12.71 years (range 18-65). Overall, the prevalence rate of PTSD was 13.3%. None of the cases had been previously diagnosed as having PTSD. Females had a higher rate of 17.9% (n = 67), compared to the males 11.7% (n=197). The majority of those with PTSD (42.9%) were young, 20 - 29 years. Other risk factors were having post-primary education (62.9%), experiencing the first motor vehicle accident (14.1%), previous psychiatric illness, and other medical illnesses. The type of accident, role/status and immediate reactions to the accident were not significant. CONCLUSIONS PTSD following motor vehicle accidents is common. Although the MVA survivors do develop significant rates of PTSD, it is not easy to identify those at risk but some of the parameters documented in this study may help. A multi disciplinary approach is therefore essential in the management of the RTA survivors at the orthopaedic and trauma clinics if their physical and psychological needs are to be adequately addressed
