Clinical Trial: Pregnancy Specific Nausea Questionnaire (PUQE) Translated and Tested in Norwegian

Study Status: Completed
Recruit Status: Completed
Study Type: Observational [Patient Registry]

Official Title: Case-cohort Validation Study of Pregnancy Unique Questionnaire of Emesis (PUQE) in Norwegian

Brief Summary: Nausea in early pregnancy (emesis gravidarum) is very common but most often self-limiting. Hyperemesis gravidarum; where nausea and vomiting is severe and protracted is potentially dangerous for the woman and her foetus and necessitates hospital treatment. An English questionnaire (PUQE; Pregnancy Unique Questionnaire of Emesis) exists that can differentiate between uncomplicated emesis and the severe hyperemesis condition. This questionnaire has been translated to Norwegian. The investigators want to test the ability of this questionnaire to differentiate the grade of nausea/vomiting between a group of presumed normal pregnant woman and patients treated for hyperemesis gravidarum in a Norwegian population. The investigators also want to relate the PUQE questionnaire scoring to the women/patients' self-reported nutritional intake during 24 hours.

Detailed Summary:

This is a prospective case-control study validating Pregnancy Unique Questionnaire of Emesis (PUQE) in a Norwegian population. The questionnaire has been translated from English to Norwegian by authorized translators. The Norwegian questionnaire's title is Svangerskaps Utløst Kvalme Kvantifisering (SUKK). The Norwegian version has been independently back-translated to English. The back-translated version has been approved by the original author Gideon Koren.

The primary objective is to evaluate if the questionnaire score is significantly different between a group of presumed healthy pregnant woman and a group of patients hospitalized with hyperemesis gravidarum.

The women will also fill in a self-reported 24-hours nutritional intake diary and this will be related to the Pregnancy Unique Questionnaire of Emesis (PUQE)score. For patients hospitalized with hyperemesis gravidarum the Pregnancy Unique Questionnaire of Emesis (PUQE)score both at admission and discharge will be compared.

Background clinical information for both groups at enrollment will be recorded as well as pregnancy outcome for woman and child.

The study has been approved by the Institutional Board as well as the Norwegian Regional Ethical Committee (REK Norway). Women will be included after giving informed written consent. Data will be stored electronically, anonymised, at a designated research server in accordance with the institutional research rules.

The sample size have been determined on basis of a similar study evaluating different nutritional status in emesis and hyperemesis patients, using 20 patients in each group. We aim to include 30 patients in each group.

Pregnancy Unique Questionnaire of Emesis (PUQE) score range from 3 to 15. Scores reported for the first 24 hours after inclusion will be compared between hyperemesis patients and healthy pregnant control women
