Objective-Alcohol misuse by college students places resource demands on colleges and universities, including the provision of medical services for intoxicated students. We harvested archival data to document the prevalence of alcohol-related ambulance utilization and to explore factors associated with ambulance use.Method-We reviewed two years of university ambulance records, and determined which trips were alcohol-related and their demographic, descriptive, and medical correlates.Results-Alcohol use was associated with 17% and 16% of all university-based ambulance trips in 2005 and 2006, respectively. When alcohol was involved, patients were more likely to be under 21 years of age, less alert, and more likely to receive advanced life support. Alcohol-related ambulance trips were more likely to occur on weekends, to involve transport from a residence hall, and to a hospital.Conclusion-Alcohol misuse is associated with 1 out of every 6 campus-based ambulance runs, a hidden cost of student alcohol misuse.Keywords alcohol abuse; emergency medical services; student health services High volume alcohol use peaks among young adults between the ages of 18-25; 1 nearly 42% have reported heavy (binge) drinking, defined as 5 or more drinks on an occasion in the last month. Alcohol use increases risk for unintentional injuries (including motor vehicle accidents), homicide and suicide, the three leading causes of death in the young adults. 2 A particularly high risk subgroup are young adults enrolled full-time in college; college students drink more heavily than their same-age peers not attending college. 1 Alcohol misuse by college students affects the drinkers themselves, their peers, and the environment. 3 Approximately 44% of students report heavy drinking within the last 2 weeks, with attendant hangovers, blackouts, and academic difficulties. 4 Even more concerning are the 500,000 unintentional injuries and the 1,700 deaths among student drinkers each year. 5 Peers sharing the college environment with heavy drinkers report having studies or sleep interrupted, 4 and an estimated 600,000 have been assaulted or injured by a drunken student. 5 Excessive drinking is also associated with property damage as well as the need for additional security, judicial, and student affairs personnel. Alcohol misuse by students also places a burden on health services. For example, 16% to 33% of student visits to university-based emergency departments (EDs) are alcohol-related; 6-8 in contrast, only 3% of ED visits by adolescents and young adults in the general population are alcohol-related. 9 A little-recognized cost of student drinking involves the use of campus ambulance services. Even though 14% of ED visits involves ambulance transport, 10 few data document the extent to which university-based ambulance services are needed as a result of student drinking.This study was conducted to fill this gap in the literature by examining the prevalence and correlates of alcohol-related ambulance runs on a university campus.
