Abstract

                This research aimed to study factors affecting the utilization of the emergency medical services (EMS) for the emergency and crisis patients in Ubon Ratchathani province. It was designed as a matched case-control retrospective analytical study between 15 October 2558- September 2559. Sample was 668 participants who were categorized into the study group (334 participants) and the control group (334 participants). The data were collected by using self-reporting questionnaire and qualification by index of congruence as over 0.5 and reliability in all of parts over 0.7; and were analyzed by percentage, mean, standard deviation, Odd ratio, and multivariate analysis (conditional multiple logistic regression with 95% confidence estimation at 0.05 significant level). Results showed that the study group and the control group were mostly male (53.8% in both groups), and majority age group was 52-73 years old. The main cause of emegencies was traffic accident (34.7% in the study froup and 47.9% in the control). There were 8 variables that could predict 59.7% of emgency medical services utilization which included habits, educa-tion level not over high school level, higher social support, higher perceived EMS utilization, self-confident, chronic illness, aging, and no personal vehicle. Such factors should be addressed in order to promote access to and utilization of emergency medical services in the province.
