SANTA MARIA, Margarita; JARAMILLO, Mario Andrés; OTERO REGINO, William  and  GOMEZ ZULETA, Martín Alonso. Validation of a Questionaire Regarding Gastroesophageal Reflux (GERD) in a Colombian Population. Rev Col Gastroenterol [online]. 2013, vol.28, n.3, pp.199-206. ISSN 0120-9957.

Background: Gastroesophageal reflux disease (GERD) is a chronic condition resulting from retrograde flow of the gastroduodenal contents into the esophagus and/or adjacent organs. Prevalence of GERD in Western countries ranges from 10% to 20%. GERD accounts for 4% of consultations with family doctors. Objective: The objective of this study was to validate a scale for the Colombian GERDQ (Gastroesophageal Reflux Questionnaire) and develop a diagnostic method for determining the severity of GERD. Materials and Methods: A diagnostic scale was validated on 84 patients and retested on 55 patients in the gastroenterology practice of the Clinica Fundadores in Bogotá. All patients diagnosed with GERD by gastroenterologists from January to April 2013 were asked to answer the GERD questionnaire. Results: Multiple correspondence analysis showed that when GERDQ has an 8 point score its correlation with diagnoses made by gastroenterologists is 89% which implies a 92% correlation with the scale of Montreal. Conclusion: This study shows that the GERDQ is a valid instrument for use in Colombia by general practitioners, internists and geriatricians for diagnosing GERD.
