Key result
Swiss survey estimates ~1 million annual anesthesias require massive propofol supply, highlighting pandemic management needs.
Why the study?
Details of current anaesthesia practice in Switzerland were unknown but urgently needed to manage anaesthesia drug supply during the COVID-19 pandemic.
Observational (n=185)
Yes
A national survey of Swiss anaesthesia institutions provided detailed data on anaesthesia activity, enabling the projection of annual anaesthetic drug requirements to manage supply during the COVID-19 pandemic.
National anaesthesia volume data enable targeted drug supply planning during shortages; leaves open whether repeated surveys are required elsewhere.
BACKGROUND: In Switzerland, details of current anaesthesia practice are unknown. However, they are urgently needed to manage anaesthesia drug supply in times of drug shortages due to the pandemic. METHODS: We surveyed all Swiss anaesthesia institutions in April 2020 to determine their annual anaesthesia activity. Together with a detailed analysis on anaesthetic drug use of a large, representative Swiss anaesthesia index institution, calculations and projections for the annual need of anaesthetics in Switzerland were made. Only those drugs have been analysed that are either being used very frequently or that have been classified critical with regard to their supply by the pharmacy of the index institution or the Swiss Federal Office of Public Health. RESULTS: The response rate to our questionnaire was 98%. Out of the present 188 Swiss anaesthesia institutions, 185 responded. In Switzerland, the annual number of anaesthesias was 1'071'054 (12'445 per 100'000 inhabitants) with a mean anaesthesia time of 2.03 hours. Teaching hospitals (n = 54) performed more than half (n = 572'231) and non-teaching hospitals (n = 103) provided almost half of all anaesthesias (n = 412'531). Thereby, private hospitals conducted a total of 290'690 anaesthesias. Finally, office-based anaesthesia institutions with mainly outpatients (n = 31) administered 86'292 anaesthesias. Regarding type of anaesthesia provided, two thirds were general anaesthesias (42% total intravenous, 17% inhalation, 8% combined), 20% regional and 12% monitored anaesthesia care. Projecting for example the annual need for propofol in anaesthesia, Switzerland requires 48'573 L of propofol 1% which corresponds to 5'644 L propofol 1% per 100'000 inhabitants every year. CONCLUSIONS: To actively manage anaesthesia drug supply in the context of the current pandemic, it is mandatory to have a detailed understanding of the number and types of anaesthesias provided. On this basis, the Swiss annual consumption of anaesthetics could be projected and the replenishment organized.

Hofer et al. (2021) conducted an observational in Anaesthesia drug supply during COVID-19 pandemic (n=185). Anaesthesia services and drug consumption was evaluated on Annual number of anaesthesias and projected need for anaesthetics. In Switzerland, 1,071,054 anaesthesias were performed annually, requiring an estimated 48,573 L of 1% propofol, highlighting the need for detailed service data to manage drug supply during pandemics.
