Avalanche Survival Rates in Switzerland, 1981-2020.

ABSTRACT:

Importance

Survival probability among individuals critically buried by avalanche is highly time dependent, which was demonstrated 30 years ago. However, it remains unclear whether avalanche survival probability has changed over time.

Objective

To assess the avalanche survival rate and probability as well as the rescue probability over the past 4 decades.

Design, setting, and participants

In this cohort study, avalanche data from Switzerland that were collected by the WSL Institute for Snow and Avalanche Research (SLF) in Davos were analyzed from the winter beginning in 1981 to that beginning in 2020 and compared with data from the period 1981 to 1990. Data were analyzed from January to April 2024.

Exposure
