Prediction models for the risk of postoperative nausea and vomiting

Abstract

This is the protocol for a review and there is no abstract. The objectives are as follows: Identify all prognostic models developed for estimating the risk of PONV. Describe the characteristics (e.g. included predictive factors, apparent predictive accuracy in the developmental data set) of prognostic models. Appraise the predictive accuracy (external validation, including discrimination and calibration) of these models. Report and, if possible, meta-analyse the performance of models, particularly those that have been validated in external populations. Identify impact assessments of PONV prediction models that have been performed. Appraise and make recommendations for PONV prediction models that may be useful for patient care.Copyright © 2015 The Cochrane Collaboration.
