This is a cross-sectional study of symptom burden and clinical management. A subset of patients who have attended the Primary Care (PC) office with reflux symptoms during a retrospective period of 4 months (Index Visit) are invited to complete health survey questionnaires and partake in a subject-physician/study nurse interview (Visit 1), in order to assess the type, intensity and frequency of GERD symptoms at both visits and describe the treatment provided. Additionally, the impact of GERD on subjects' life, productivity and willingness to pay for GERD symptom relief will be explored. This design will give a "real-life" clinical practice picture in a representative population of PC doctors and subjects.

Study Population

Subjects attending PC offices with reflux symptoms. Subjects must not have participated in any other clinical study in the time window between the Index Visit and Visit 1.

In the reasons for the Index Visit section of the medical record mention of acid regurgitation and/or heartburn symptom(s) or GERD diagnosis or GERD complications has to be explicit or a treatment decision (prescription) in a previously diagnosed subject although no mention of symptoms is made.

Exclusion Criteria:

  • Prophylactic PPI use to reduce the risk of ulcers in subjects being treated with NSAIDs
