Plain English Summary
Background and study aims
Gastro-oesophageal reflux disease (GORD) refers to a range of disorders mainly caused by the backward flow of acid from the stomach into the oesophagus (gullet). Heartburn and acid regurgitation (a bitter burning taste at the back of the mouth) are the most typical symptoms of GORD. GORD is a chronic disease (prevalence 10-20 % in Europe) that has a detrimental effect on a person’s quality of life (QoL). It is mainly treated in primary care (for example, the GP surgery) with a proton pump inhibitor (PPI) once or twice a day, or on demand. There is conflicting data on which of these two treatment regimens is better and this lack of knowledge is likely to be related to the difficulties of performing large studies in primary care. In addition, patient reported outcomes such as symptom frequency and severity, QoL and self-rated health are important but are rarely used in primary care today. This study has been developed to answer the question “what gives most symptom relief and improvement in quality of life in patients with GORD, on demand or continuous use of proton pump inhibitors?”
Who can participate?
Adults aged between 18-65 years, diagnosed with GORD that responds to PPI treatment.
What does the study involve?
Participants are randomly allocated into one of two groups. Those in group 1 are treated with regular use of proton pump inhibitors. Those in group 2 are treated with on demand use of proton pump inhibitors. In this pilot study, the TRANSFoRm* tool is tested in 5 countries with 8 primary care practices each, including 20 patients per practice. The progress of each patient is followed for 8 weeks.
* TRANSFoRm is a project to develop tools to help in the running of clinical trials in primary care, including the collection of both care reported outcomes and patient reported outcomes . It also aims to develop a suite of software tools and underlying infrastructure to support primary and epidemiological research
