Anecdotal evidence suggests that university students are accessing local Emergency Medical Services (EMS) more frequently, usually as a result of alcohol consumption. In doing so, they endanger their personal health and create challenges for EMS and local hospitals. This study examined EMS use by young adults (ages 16-24 years) to identify differences between university students and youth in the Region of Waterloo, and to determine predictors of transport to hospital. This cross-sectional study used retrospective data collected during a six-year period (2006-2011) from a large, mixed urban and rural municipal ambulance service located in southwestern Ontario. Data were extracted from electronic ambulance call reports completed by paramedics responding to 9-1-1 calls. Individuals accessing EMS within the university zone were compared with those outside this area on demographics, patient presentation, pick-up locations, transport status, and
9-1-1 call generation characteristics. Given the large sample size (N = 16,577), and the probability of a type I error, we determined statistical significance based on a 20% change in the odds ratio (i.e., OR of 1.20). Among university students, across years, the number of calls that involved alcohol rose from 29% to 38%. Based on the OR, university students, compared with other young adults, were 2.6 times more likely to call EMS with alcohol as a contributing factor, 1.3 times more likely to be assigned a low priority by paramedics, and 1.4 times more likely to refuse transport. They were 1.9 times more likely to be picked up in a bar and 1.8 times more likely to call 9-1-1 at night. Using logistic regression, significant predictors of transport to the hospital (yes/no) were: a scene time less than 20 minutes; advanced life support (ALS) care provided; pick-up at a school; and day of the week. These findings suggest that there has been an increase in alcohol-related EMS calls by Region of Waterloo university students. EMS services need to be aware of these factors when developing deployment strategies. Further, there is a need to coordinate with university administrators in order to develop strategies to optimize the care of students who have been using alcohol, particularly those who refuse transport to hospital.
