Key result
The Apfel and Koivuranta scoring systems showed lower than expected discrimination for predicting postoperative nausea and vomiting, with area under the ROC curves of 0.63 and 0.66, respectively.

Do the Apfel and Koivuranta scoring systems accurately predict postoperative nausea and vomiting in adult surgical inpatients?
Absolute Event Rate: 0.63% vs 0.66%
The Apfel and Koivuranta scoring systems for postoperative nausea and vomiting showed lower than expected discrimination and calibration in this validation cohort.
Bosch et al. (2005) conducted an observational in Postoperative nausea and vomiting (n=1,388). Apfel et al. scoring system vs. Koivuranta et al. scoring system was evaluated on Predictive accuracy (discrimination and calibration) for postoperative nausea and vomiting. The Apfel and Koivuranta scoring systems showed lower than expected discrimination for predicting postoperative nausea and vomiting, with area under the ROC curves of 0.63 and 0.66, respectively.
