The number of ambulance calls and the number of people carried in emergencies in japan has been increasing remarkably every year. Among the factors that adversely affect the time needed for ambulance transport, one factor for which intervention is possible is the time it takes to choose a medical receiving facility. This research clarified the characteristics of the time and location in which the choice of hospital was difficult. The research covered a one-year period from January 1 through December 31, 2014, looking at all incidents of ambulance transport for patients in one prefecture of Japan except pediatrics. Cases with 4 or more referrals were adopted as an indicator of difficulty in choosing a hospital. Using binary logistic regression analysis, odds ratios with 95% confidence intervals were computed for the times and locations of emergency calls, and the degree of injury or illness. A comprehensive analysis was performed, and stratified analysis by Major Diagnostic Category was performed. The relationship between the time, location, and severity of medical emergencies were examined using the number of referrals as an indicator of difficulty with hospital choice in ambulance transport. This research clarified that cases late at night during weekends and holidays and moderate and mild injuries had the most difficulty, and that the problems depended on the secondary medical district.
