Dell-Kuster S, Gomes NV, Gawria L, et al. Prospective validation of classification of intraoperative adverse events (ClassIntra): international, multicentre cohort study. BMJ. 2020;370:m2917. doi:10.1136/bmj.m2917.
This cohort study enrolled 18 sites across 12 countries to assess the validity of a newly developed classification system (ClassIntra v1.0) for assessing intraoperative adverse events. Results indicate that the tool has high criterion validity and can be incorporated into routine practice in perioperative surgical safety checklists or used as a monitoring/reporting tool.
