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 to present the most important insights from the ISOS data and are extremely pleased with the quality of data collection and analysis, this has lead to the publication of a number of additional papers as found below -
