Join SUSTAIN-EUROPE: Mapping anaesthesia practice across Europe
Climate change poses an escalating threat to health worldwide.¹˒² Anaesthesiology societies have therefore called for action to reduce the environmental impact of clinical care.³–⁶ Their recommendations include using regional anaesthesia and total intravenous anaesthesia where clinically appropriate and, when inhalational anaesthesia is required, favouring sevoflurane with minimal fresh gas flow.
However, the extent to which these approaches are used in everyday clinical care remains insufficiently documented. Europe-wide data on anaesthesia techniques, volatile anaesthetic use, fresh gas flow and ventilation practices are still limited.
Building a contemporary picture of anaesthesia practice
SUSTAIN-EUROPE will address this knowledge gap through a large, multicentre, prospective, observational study of routine anaesthesia practice in adult and paediatric populations. The study aims to enrol approximately 8,000 patients across Europe. Participating centres will collect routine intraoperative data over five working days using a dedicated data-entry app. The primary endpoint is the type of anaesthesia provided, including inhalational general anaesthesia, total intravenous anaesthesia, regional anaesthesia, sedation, combinations of techniques and monitoring only.
Secondary endpoints include sustainability-related parameters, such as the inhalational agent used and fresh gas flow, as well as ventilation-related variables, including tidal volume relative to ideal body weight and ventilation pressures.
By documenting how anaesthesia is delivered across different hospitals and healthcare settings, SUSTAIN-EUROPE will provide a contemporary snapshot of practice across Europe. The findings will help identify variations in care and potential opportunities for future research and more environmentally sustainable anaesthesia practice.

Designed for straightforward participation
Participation has been designed to minimise the workload for local teams. Each centre will collect data for only five working days using a short case report form and, for the first time within the ESAIC Clinical Trial Network, a dedicated app supporting efficient data entry.
Anaesthesiology departments of all sizes are encouraged to participate. No previous research experience or university affiliation is required.
SUSTAIN-EUROPE is supported by the European Society of Anaesthesiology and Intensive Care Clinical Trial Network following its selection for an ESAIC CTN Grant. The study is registered on ClinicalTrials.gov under NCT07252973.
