Welcome to the International Surgical Outcomes Study (ISOS)

We are delighted to announce that the main ISOS report has now been accepted for publication in the British Journal of Anaesthesia. As the now leading international anaesthetic journal, this is an excellent platform for our work. All investigators have been named in the ISOS group included in the publication. The paper will be published on an open access basis, but you are free to download and read the final authors version here.

We have been working for some months now, to present the most important insights from the ISOS data. We are extremely pleased with the quality of data collection and analysis, and we have recorded a webcast to present the main results. This can be found from the link below.

The final investigator list can be found here, any further changes we are notified of will be included if we can, but as the paper has been accepted for publication this may not be possible.


Thank you for your interest.
