The Association of Guideline-Directed Prophylaxis With Postoperative Nausea and Vomiting in Adult Patients: A Single-Center, Retrospective Cohort Study

Consensus guidelines for postoperative nausea and vomiting (PONV) prophylaxis recommend a risk-based approach in which the number of antiemetics administered is based on a preoperative estimate of PONV risk. These guidelines have been adapted by the Multicenter Perioperative Outcomes Group (MPOG) to serve as measures of clinician and hospital compliance with guideline-recommended care. However, the impact of this approach on clinical outcomes is not known.
