The Use of International GerdQ Questionnaire
Observational Non-interventional Study on the Use of International GerdQ Questionnaire for the Diagnosis of Gastroesophageal Reflux Disease in the Russian Practice

There are three main directions for use GerdQ in practice. First of all, GerdQ can be used to diagnose GERD with an accuracy comparable to the accuracy of diagnosis of GERD by the specialist (gastroenterologist). Using GerdQ can evaluate the impact of disease on the patient's life and help in choosing treatment of GERD, as well as direct assessment of treatment efficacy.

In connection with mentioned above, this study is devoted to the estimation of possibility to use GerdQ in routine practice of Russian physicians.
