Study objective:

To determine the level of medical care required for mass gatherings and describe the types of medical problems encountered in a major winter event.

Design:

Standard charts were available for 3,395 encounters. Interviews with medical staff showed that the few unrecorded encounters were for very minor medical problems. A four-tiered triage system (low, moderate, urgent, and emergent) developed before the Games was applied to each chart retrospectively by a single emergency physician. Chi-squared tests were used to test significant differences.

Setting:

This winter sporting and entertainment event had 12 urban and rural venues. Medical staff (98 physicians, 161 nurses, and 337 first-aid attendants) were based in 28 advanced life support (ALS) clinics. The medical service operated for four weeks.

Type of participants:

There were 1.8 million spectator-days. Patients included spectators, athletes, and support staff.

Interventions:

First-aid attendants referred patients to the clinics, where nurses conducted initial assessments and referred patients to physicians at the venue, or more rarely, to local hospital emergency departments. Paramedic ambulances were stationed at the venues. The triage system was not used for patient management.

Measurements and main results:

Only 40 urgent and one emergent medical problems were encountered. The majority of patients could have been managed by trained nurses working alone under standing orders. Fifty patients were transported to the hospital by ground ambulance and three by helicopter. No significant differences were found in the low acuity levels experienced at indoor urban venues, outdoor urban venues, and the rural cross-country ski venue. The Alpine ski venue was characterized by significantly higher acuity and a long prehospital transfer phase.

Conclusion:

Owing to the low acuity encountered and the availability of Calgary's ALS ambulance service, we concluded that physician-based ALS teams were not required for patient management at the urban venues. Such teams were found to be required at the rural Alpine ski venue. Other reasons for using physicians are discussed, as is development of a standard triage system for mass gatherings.

      Obviously, the injuries and diseases of the musculoskeletal system, mainly involving lower limbs, were preponderant in Torino, and the very high number of repeat visits by certain athletes was mainly due to recurrent injuries and musculoskeletal diseases or related relapses (7). Moreover, the remarkable presence of respiratory and gastrointestinal illnesses, frequently related to infections, is typical of winter events and not summer events (11,12,29). According to the specificity of illnesses and injuries affecting athletes in our setting, the organization of the polyclinics could be recommended for future events, along with the suggestion for improvement of the busiest services (orthopedics, radiology, and physiotherapy) and the shift of less-used services (ear-nose-throat care, ophthalmology, and dentistry) to on-call services.

      Large events with multiple venues such as the Olympic, Paralympic, or World Masters Games will necessitate many volunteers who have varying levels of training. The authors' experience and that of others at these events has shown that most medical encounters have been of low acuity [30–34]. In addition, several studies have demonstrated that nurses and paramedics can perform effectively in triage and stabilization of medical problems in areas with established emergency medical services (EMS) and under the guidance of standardized orders developed by a physician [30,31,33].
