The Pregnancy-Unique Quantification of Emesis (PUQE) is a scoring system to quantify the severity of nausea and vomiting of pregnancy (NVP). Based on quantification of the 3 physical symptoms of NVP (nausea, vomiting and retching), PUQE closely correlates with the validated but much more complex Rhodes' score. We examined the ability of PUQE to predict four independent aspects of NVP: (a) pregnant women's ability to take multivitamins. (b) rates of emergency room visits and hospitalisation for NVP. (c) health cost of NVP. (d) women's self scores of well-being in NVP. Using large prospective cohorts of women for each end point, severity of NVP measured by PUQE had significant predictive value for all 4 aspects sought. PUQE has been validated through 4 independent clinical outcomes of direct importance and relevance for NVP. The simplicity of PUQE and the ease of its execution make it a practical tool for both clinical follow-up and research.
