However, little is known about the use of this technology across nations.<h4>Methods</h4>This is a secondary analysis of a previously published observational study. Patients aged 16 years and over undergoing major non-cardiac surgery in a 7-day period in April 2011 were included into this analysis. The objective is to describe prevalence and type of cardiac output monitoring used in major surgery in Europe.<h4>Results</h4>Included in the analysis were 12,170 patients from the surgical services of 426 hospitals in 28 European nations. One thousand four hundred and sixteen patients (11.6 %) were exposed to cardiac output monitoring, and 2343 patients (19.3 %) received a central venous caPerioperative medicine (London, England)Variation in haemodynamic monitoring for major surgery in European nations: secondary analysis of the EuSOS dataset.PMC4581514RP_2014-04-022CS/08/08/17Moreno RPAldecoa CPearse RMBeilstein CMHofer CKAhmad TRhodes AMolnar ZSander MNovak-Jankovic VfalseVariation in haemodynamic monitoring for major surgery in European nations: secondary analysis of the EuSOS dataset.<h4>Background</h4>The use of cardiac output monitoring may improve patient outcomes after major surgery.
