Ambulance Use by International Travelers in Japan: A Retrospective Descriptive Study

Reports indicate that 22%–64% of travelers experience some illness when in a foreign country. To date, no prior study has reported the use of ambulances by travelers or the epidemiology of travel-related injury.

In this retrospective study, we aimed to describe ambulance use by international travelers, including the rates of travel-related injury and illness. To do so, ambulance dispatch data from January 1, 2010 to December 31, 2018 was used.

Overall, of the 43 201 cases of ambulance use during the study period, 524 (1.2%) were international travelers. Ambulance use by international travelers increased from 0.35% in 2010 (15/4311) to 2.54% in 2018 (125/4913), an average annual increase of 0.27%. Of the international travelers, 392 (74.8%) had minor complaints, 110 cases (21.0%) had moderate complaints, 280 (53.4%) had internal disease, and 223 cases (42.6%) had suffered trauma. Regarding location, 253 (48.3%) were from a hotel/lodge, 83 (15.8%) were from a road/parking, and 30 (5.7%) were in the forest/mountain.

Most international travelers use ambulances for minor complaints, typically internal disease or trauma, and approximately half access the service from a hotel or lodge.
