The Factors Relating to Survival Probability of the Traffic Accident Patients at a Tertiary Hospital in Nakhon Pathom Province

Abstract

          This research study was a descriptive analytical research, aimed to analyze the factors related to the probability of survival in traffic accident patients by analyzing the retrospective data. The samples were traffic injured patients registering at Nakhonpathom Hospital from January 1st , 2012 to December 31st, 2012. The Injury surveillance data of Nakhonpathom Hospital were analyzed by injury surveillance program (TRISS Methodology) and computerized program, The descriptive statistics; frequencies, percentage, correlations  and multiple regression for the prediction of the probability of survival equation were applied in the study.

          The research findings showed that the traffic injured patients registering at accident and emergency department, Nakhonpathom Hospital in the year 2012 were 5,622 cases, most of the samples were male 3,486 cases (62.00%) and female samples were 2,136 cases (38.00%). The majority of the samples age were 11-20 years (29.70%) and 21-30 years (22.8%). Most of the type of injury were blunt injuries 99.2% and penetrating injuries 0.67%. The majority injuries used vehicles were motorcycles 4,648 cases (82.68%). The injured samples drink alcohol 18.30% not drink alcohol 78.83%. motorcyclists wear helmet 15.88% not wear helmet 83.39%, car van/pickup truck and bus driver use seat belt 15.75% not use seat belt 80.09%. Gender had a positive correlation with the probability of survival  r = .061** significant at the 0.01 level. Type of vehicles, motorcycle had positive correlation with the probability of survival  r = .036* significant at the 0.05 level, car and van/pickup had negative correlation with the probability of survival r = -.033* and -.037* respectively  significant at the 0.05 level.

          The factors related to the probability of survival involving with drinking alcohol, wearing helmet and using seat belt showed that drinking alcohol had negative correlation with the probability of survival r = -.325** significantly at the 0.01 level, wearing helmet and using seat belt had no correlation with the probability of survival and the prediction equation for the probability of survival of the traffic injured patients was as follow : probability of survival = 0.981 - .002 (drinking alcohol)  + .011 (riding motorcycle)
