The primary objective of the cohort study is to evaluate the level of burnout in Swiss physicians and how it fluctuates across 6 different timepoints in a period of 3 years.

Secondary objectives:
• To explore constructs related to Swiss physicians’ wellbeing and emotions, including job satisfaction, moral distress, reaction to uncertainty, emotional regulation, resilience and coping, and their change at 6 different times across 3 years.
• To explore the extent to which Swiss physicians engage in end-of-life conversations with their patients, as well as the frequency, perceived competency and comfort level with these conversations.
• To assess whether burnout scores and scores in other constructs of interest may be associated with sociodemographic characteristics and related variables, such as years of practice, etc.
• To determine whether constructs related to physician wellbeing and emotions are associated with physicians’ comfort with end-of-life conversations.

The primary objective of the nested RCT is to evaluate the impact of two positive psychology-based interventions on physician’s emotional exhaustion. We hypothesise that participation in the interventions will reduce physicians’ emotional exhaustion at 6-months after the intervention. Between the two interventions, we hypothesise that the intervention focused on job aspects will have a greater effect in reducing emotional exhaustion than the more general intervention.

Secondary objectives
• To ascertain whether the interventions have an effect on other constructs of interest related to Swiss physicians’ wellbeing and emotions, including job satisfaction, moral distress, reaction to uncertainty, emotional regulation, resilience and coping.
• To determine whether the interventions have an effect on physicians’ perceived comfort with end-of-life communication.
