Prevalence and Impact in Work Productivity of Gastroesophageal Reflux Disease (GERD) in Primary Care Patients With Upper Gastrointestinal (GI) Symptoms Using GerdQ (GerdQ-Greece)

December 24, 2009 updated by: AstraZeneca

A Cross-sectional Study on the Prevalence and Impact in Work Productivity of GERD in Primary Care Patients With Upper GI Symptoms Using the Novel Questionnaire GERD-Q. The Greek GERD-Q Study

The purpose of the study is to provide data on the GERD prevalence as percentage of patients with upper GI symptoms that are identified with GERD using the GerdQ Questionnaire. Furthermore the study aims to estimate GERD prevalence in patients based on their symptoms as they respond to a physician's questionnaire, to observe possible variations between the two methods (physicians' symptom rating and GerdQ), to objectively measure treatment response and to identify the percentage of patients that may require alterations of their treatment. Finally, to describe the impact of GERD symptoms on work productivity.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Time Frame
GERD prevalence as percentage of patients with upper GI symptoms that are identified with GERD using the GerdQ Questionnaire (GerdQ score >=8).
Time Frame: Single Visit - once
Single Visit - once

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Time Frame
Estimation of GERD prevalence in patients based on their symptoms as they respond to a physician's questionnaire and to observe possible variations between the two methods (physicians' symptom rating and QerdQ)
Time Frame: Single Visit - Once
