Backcountry Skiers, Avalanche Trauma Mortality, and Helmet Use

Wilderness Medical Society Clinical Practice Guidelines for Prevention and Management of Avalanche and Nonavalanche Snow Burial Accidents: 2024 Update

To provide guidance to the general public, clinicians, and avalanche professionals about best practices, the Wilderness Medical Society convened an expert panel to revise the evidence-based guidelines for the prevention, rescue, and resuscitation of avalanche and nonavalanche snow burial victims. The original panel authored the Wilderness Medical Society Practice Guidelines for Prevention and Management of Avalanche and Nonavalanche Snow Burial Accidents in 2017. A second panel was convened to update these guidelines and make recommendations based on quality of supporting evidence.

Freeriding-Only a need for thrill?: Comparing different motives and behavioural aspects between slope skiers and freeride skiers

OBJECTIVES

To compare professional freeride skiers (an experienced high-risk cohort) with recreational freeride skiers (a less experienced high risk cohort) and slope skiers (a low-risk sport cohort) in regard to their motives and their reported accident involvement.

DESIGN

Case-control study.

METHODS

In an online survey, skiers completed the German Sensation Seeking, Emotion Regulation and Agency Scale and the German Accident and Close Calls in Sport Inventory. Freeriders were further asked about their risk-management strategies and their use of safety equipment. For every professional freerider (total 31; 29% female) within the sample, two matched controls (age, gender) were allocated (slope skier and recreational freerider). Univariate analyses of variance (ANOVAs) and Chi-square differences were calculated.

RESULTS

Freeriders showed significantly higher sensation seeking scores than slope skiers. No differences were found in the experience of agency while participating; however freeriders experienced higher agency transfers after the activity than slope skiers. No further motivational disparities between recreational or professional freeriders were shown. Both freeride samples reported a significantly higher accident and close call involvement than slope skiers. Accident and close call involvement was not predicted by motives of participation.

CONCLUSIONS

Freeriding might provide beneficial transfer effects as shown through a higher agency transfer, for participants into aspects of everyday life. Nevertheless it should not be ignored that the potential behavioural gain of freeriding is at the cost of a higher risk which is underlined by the higher involvement in accidents and experienced close calls of freeriders compared to slope skiers.

A Qualitative Approach on Motives and Aspects of Risks in Freeriding

Recent research has shown that there are multiple motives for participation in high-risk sport; however these results have come from studies that consider a number of different sports. Therefore, the aim of the present study was to better understand the motives and risk-related aspects of freeriding, using a qualitative approach. Semi-structured interviews were conducted with 40 professional and semi-professional freeride skiers and snowboarders. All freeriders were highly experienced, of different age (19–44 years; 27.5 ± 4.5 years), gender (female = 13), and profession (professional athletes = 11). Analyses were done using MAXQDA software following a code theme approach. Mixed methods analyses using χ²-tests were computed for age (<25 years ≥) and gender (female/male) on motives and risk factors. Five emerging themes were found, namely Challenge (n = 36), Friends (n = 31), Nature (n = 27), Balance (n = 26), and Freedom (n = 26). A sixth theme Habit (n = 13) was allocated as a subtheme due to minor responses. With regard to risk management, participants decided upon a risk calculation strategy which included multiple factors (e.g., planning, conditions, current situation, knowledge, and experience). Trusting in one's own abilities, avoiding negative fear and having trusted partners were among the risk factors. Deliberately seeking out dangerous situations was not a motive. χ²-tests revealed no gender or age differences regarding aspects of risk (range of p-scores: p = 0.17–1.00) or motives (p = 0.16–1.00). Freeriding was shown to provide positive effects through participation. Some important factors seem to be motivational drivers for freeriders: challenging oneself, experiencing nature, contributing to deep friendships, freeriding as a counterbalance to everyday life and escape from restrictions. Contrary to prior research reports on sensation seeking, experienced freeriders do not search the risk; they seem to minimize it based on knowledge and experience. Analyses of the present data did not show any gender or age differences, which may suggest that experience plays a more important role in high-risk sports than age or gender. Future research should qualitatively investigate further terrain based activities and implement motives and risk-related factors in quantitative research.

Wilderness Medical Society Practice Guidelines for Prevention and Management of Avalanche and Nonavalanche Snow Burial Accidents

To provide guidance to clinicians and avalanche professionals about best practices, the Wilderness Medical Society convened an expert panel to develop evidence-based guidelines for the prevention, rescue, and medical management of avalanche and nonavalanche snow burial victims. Recommendations are graded on the basis of quality of supporting evidence according to the classification scheme of the American College of Chest Physicians.
