Evaluation of treatment pattern and symptom control in patients with gastroesophageal reflux disease: multihospital questionnaire survey on the current situation in Korea

Abstract

Proton pump inhibitors (PPIs) are the most effective treatment for gastroesophageal reflux disease (GERD); however, a considerable number of patients fail to respond to PPI therapy and complain of nocturnal heartburn and sleep disturbance. The aims of this study are to evaluate the treatment pattern of GERD-related medications and their efficacy in relieving nocturnal heartburn. A total of 334 patients with GERD receiving PPI therapy within 6 months were enrolled in a multihospital questionnaire survey from January, 2014 to March, 2015. GERD symptoms and patients' satisfaction were assessed by patient questionnaires, and treatment patterns of GERD-related medications were assessed by investigators. Among the 334 patients, 95.8% used PPI once daily and 58.6% used a half-dose of PPI. The PPI treatment pattern was changed in 26.6% of all patients, of those, 54% of the patients doubled the PPI dose, and 29.2% of the patients switched to another PPI. Approximately 60.3% of all patients were prescribed more than three GERD-related medications. The overall satisfaction rate was 61.8%, and 32.2% of patients experienced nocturnal heartburn and sleep disturbance. In the extended-release PPI group, there were fewer nocturnal symptoms compared with the conventional PPI group (10% vs. 33.7%, respectively, P = 0.027). The use of more than three medications was inversely associated with patients' satisfaction (OR = 0.355, 95% CI; 0.197-0.642, P = 0.001). Most patients were prescribed adjunctive medications other than PPIs; however, patients' satisfaction was inversely associated with multiple drugs. Patients' satisfaction was superior in extended-release PPIs than conventional PPIs for the relief of nocturnal heartburn in Korean patients.

Symptom Profile, Proton Pump Inhibitor Therapy, and Diagnostic Testing in Patients With Persistent Reflux-Like Symptoms: Results From a Population-Based Survey

“…Similarly, other surveys have found that 50% to 60% of patients with GERD required multiple GERDrelated medications to manage their symptoms. 20,21 Some limitations of this survey include the fact that all data were self-reported and no diagnostic testing was performed for this survey. Respondents were asked initially if they had ever been diagnosed with GERD or rGERD, with no separation of the 2 diagnoses.…”
