Drug and alcohol consumption at sporting mass-gathering events (MGEs) has become part of the spectator culture in some countries. The direct and indirect effects of drug and alcohol intoxication at such MGEs has proven problematic to in-event health services as well as local emergency departments (EDs). With EDs already under significant strain from increasing patient presentations, resulting in access block, it is important to understand the impact of sporting and other MGEs on local health services to better inform future planning and provision of health care delivery.

The aim of this review was to explore the impact of sporting MGEs on local health services with a particular focus on drug and alcohol related presentations.

A well-established integrative literature review methodology was undertaken. Six electronic databases and the Prehospital and Disaster Medicine (PDM) journal were searched to identify primary articles related to the aim of the review. Articles were included if published in English, from January 2008 through July 2019, and focused on a sporting MGE, mass-gathering health, EDs, as well as drug and alcohol related presentations.

Seven papers met the criteria for inclusion with eight individual sporting MGEs reported. The patient presentation rate (PPR) to in-event health services ranged from 0.18/1,000 at a rugby game to 41.9/1,000 at a recreational bicycle ride. The transport to hospital rate (TTHR) ranged from 0.02/1,000 to 19/1,000 at the same events. Drug and alcohol related presentations from sporting MGEs contributed up to 10% of ED presentations. Alcohol was a contributing factor in up to 25% of cases of ambulance transfers.

Drug and alcohol intoxication has varying levels of impact on PPR, TTHR, and ED presentation numbers depending on the type of sporting MGE. More research is needed to understand if drug and alcohol intoxication alone influences PPR, TTHR, and ED presentations or if it is multifactorial. Inconsistent data collection and reporting methods make it challenging to compare different sporting MGEs and propose generalizations. It is imperative that future studies adopt more consistent methods and report drug and alcohol data to better inform resource allocation and care provision.

Sixteen percent of all motor-vehicle fatalities are pedestrian, and accidents involving pedestrians are associated with the highest morbidity and mortality rates. Classic pedestrian injury patterns have been described. However, it has been suggested that the pattern may differ if the pedestrian is intoxicated. The role of pedestrian intoxication on motor-vehicle accident injury patterns has not been well-delineated.

Intoxicated pedestrian traffic victims have an injury pattern that is more serious and more rapidly fatal than is the pattern for nondrinking victims.

Autopsies of 223 consecutive pedestrian victims were reviewed and grouped according to the presence of alcohol in the blood: Group I, Negative (n = 165); Group II, Positive (n = 58). Gender, age, anatomic injuries, survival time, time of day, and year also were examined.

Results indicated that there were more males in Group II (79%) than in Group I (64%); younger victims, younger than 40 years old, in Group II (70%) than in Group I (34%); fewer victims older than 60 years old in Group II (8%) than in Group I (38%). Group II sustained more frequent and more severe injuries—two times the frequency of the cervical spine, liver, upper and lower extremity, pelvic and rib fractures and thoracolumbar spine injuries; three times more aortic injuries; five times more heart injuries. Death occurred within 24 hours in 95% of those in Group II and in 67% of those in Group I. Accidents occurred from 1500h to 2300h in 67% of Group II and in 53% of Group I victims.

Intoxicated pedestrian accident victims are predominantly young men, struck between 1500h and 0700h; they have an injury pattern that is two to five times more serious than is the pattern for the sober victims.
