Data collection

Investigators collected data from the patient’s file or the physician who performed the sedation, including centre characteristics (palliative care service type and team composition), patient characteristics (compliance with eligibility criteria, sociodemographic data and main pathology) and sedation characteristics (location of induction, expected duration, patient consent, collegial procedure and drugs used). According to French guidelines, the collegial procedure is a dialogue between the physician in charge, the care team and at least one physician outside of the team (online supplemental file 2). In patients who were already sedated on the day of enrolment, sedation characteristics at the time of induction were collected retrospectively.
