Further criteria can be added to the list based on patient type (e.g. monitoring skin- graft sites etc) and on the individual patient and procedure. Critercia should be primarily the responsibility of the anaesthetist, although evidence such as the World Health Organization Surgical Safety checklist demonstrate that the entire operative team should have input into the process. Therefore if there are concerns regarding drains/ dressing etc then this should be included in the handover to recovery and the ongoing ward staff.
