[Analysis of the mass skiers' injury in a large ski resort in Chongli, China].

OBJECTIVE To make a retrospective analysis of the injuries of skiing population in a large ski resort in Chongli, China and provide a basis for predicting the rapidly increasing medical needs for ski injuries in the context of the 2022 Winter Olympic Games. METHODS The basic data of all injured skiers who were treated in a medical station of a large ski resort in Chongli during the snow season from November 2017 to March 2018 and from November 2018 to March 2019 were collected. The number of skiers, the number of injuries, the causes of injuries, the types of injuries and the locations of injuries were compared. RESULTS A total of 753 skiers were injured in two snow seasons, and the estimated average incidence of injury was 4.53 and 4.46 per 1 000 skier days at the resort respectively. The average daily injury rate per 1 000 skiers in November of the two snow seasons was relatively low, with 2.20 and 1.38 cases respectively. The difference of injury rate in different months might have little to do with snowfall and more to do with passenger flow. In both the snow seasons, men accounted for more injuries than women, and injured skiers aged between 21 and 30 accounted for the largest proportion, reaching 36.8%. The main causes of injuries were falls (76.6%). The highest rate of injury was in the head and neck (17.9%), followed by the knee (17.4%) and wrist and fingers (13.3%). The most common types of injuries were contusion and trauma (29.5%) and joint and/or ligament injuries (22.2%). Children (2-12 years old) accounted for 12.7% of all the injured skiers. The rate of moderate to severe injuries (including fractures, concussions, etc.) was 34.8% among the injured patients over 50 years of age. CONCLUSION The snow resort should focus on injuries to children and elderly skiers and carry out targeted guidance and rescue work. In order to better ensure the medical safety of skiers, the ski resort medical station and nearby treatment hospitals should be equipped with a corresponding number of medical personnel and equipment, and the ski resort should further improve its safety management and rescue system.
