Using patient self-checklist to improve the documentation of risk of postoperative nausea and vomiting: an implementation project.

Background And Aims: Postoperative nausea and vomiting (PONV) is a common surgical complication, affecting 30-50% of patients and 80% in high risk populations. Successful prevention and management of PONV relies on accurately assessing individual risk prior to surgery. A valid and reliable Apfel score is commonly used to assess patients' risk.
