Measure ID

PONV 03: Percentage of patients, regardless of age, who undergo a procedure and have a documented nausea/emesis occurrence OR receive a rescue antiemetic in the immediate postoperative period.

PONV 03b: Percentage of patients, regardless of age who undergo a procedure and have a documented nausea/emesis occurrence with or without receiving an antiemetic in the immediate postoperative period.

Measure Type
Available for Provider Feedback

Postoperative nausea and vomiting (PONV) is a common and unpleasant outcome of anesthesia care that can lead to other complications, lengthening the patient’s recovery period after surgery. Effective management of PONV leads to optimal patient outcomes and comfort during the postoperative period. The Apfel score is one of the most common risk predictors for PONV and is based on 4 variables: female gender, non-smoking status, history of PONV or motion sickness and postoperative opioid administration. The presence of each additional risk factor increases a patient’s risk of PONV by twenty percent. Although including a prophylactic anti-emetic administration protocol that considers such risk factors has shown to reduce the incidence of PONV, there is high variability in this outcome. For the purpose of this measure, PONV is defined as administering any rescue medication (antiemetic MPOG Concepts in table below) or documentation of nausea or vomiting in the immediate postoperative period.

Measure Time Period
