Clinical Trial Summary

Indigestion or dyspepsia is highly prevalent worldwide. Often these symptoms are of benign nature and subside without treatment, or with lifestyle interventions like dietary modifications. Too often, gastroscopy is performed because of dyspepsia. Although this is indicated when malignancy is suspected, in a substantial part of the cases the gastroscopy is not indicated and will not achieve clinically relevant results. It is suspected that gastroscopy is often used for reassurance of patients or as a 'last resort'.

Our hypothesis is that adequate education of patients can replace this need for invasive measures. The aim of this study was therefore to reduce the volume of gastroscopies for dyspepsia, by offering patients an e-learning containing educational material on dyspepsia.

During the trial, 119 dyspeptic patients, referred for gastroscopy by the GP, will randomly be divided into two groups: One group will receive the e-learning instead of gastroscopy (intervention), the other group will receive the gastroscopy (control).

After a twelve week follow-up, change in symptom severity, disease specific quality of life and fear of disease will be compared between the two groups.


Description:

Rationale: Upper gastrointestinal (GI) symptoms, such as dyspepsia without alarm symptoms, are highly prevalent in the general population. Lifestyle modifications and medication can reduce symptoms in most patients. Guidelines state that oesophagogastroduodenoscopy (OGD) is only indicated in a selected high risk group. In spite of these guidelines, OGD referrals for dyspepsia without alarm symptoms are still substantial, subjecting patients to unnecessary risks and causing a burden on healthcare costs and endoscopic capacity. Therefore a strategy is needed to reduce the volume of OGDs in dyspepsia without alarm symptoms.

Objective: To evaluate the clinical use of a patient-centred, education based, clinical strategy to reduce the volume of endoscopies for dyspepsia in patients over 18 years of age without alarm symptoms, referred for OGD through open-access endoscopy compared to usual care.

Study design: A multicentre, randomised, controlled superiority trial, with two parallel arms and a primary endpoint of the percentage of patients receiving OGD. Intervention and usual care will be compared.

Study population: 119 Patients, aged 18 years or above, with upper GI symptoms without alarm symptoms, referred for open-access OGD.

Intervention: Patients will be offered e-learning instead of endoscopy. The e-learning will contain educational material and questionnaires. Questionnaire data will be extracted from the e-learning.

Main study endpoints: The main study endpoint is the difference in proportion of patients receiving OGD between both arms and Patient Reported Outcomes (PROMS), after a follow-up of 12 weeks.

Outcome

Type Measure Description Time frame Safety issue
Primary The difference in proportion performed OGDs between groups The difference between the two study arms in proportion of patients that have received OGD, measured 12 weeks after the initial visit to the endoscopy clinic, out of the total number of patients referred for open-access endoscopy 12 weeks
Secondary The influence of the intervention on health-related anxiety The difference between the change scores of the two study arms concerning health-related anxiety, measured by the total score on the validated Short Health Anxiety Inventory 12 weeks
Secondary The influence of the intervention on severity of upper GI symptoms The difference between the change scores of the two study arms concerning severity of upper GI symptoms, measured by the mean on the subscale scores of the validated PAGI-SYM questionnaire 12 weeks
Secondary The influence of the intervention on dyspepsia-related quality of life The difference between the change scores of the two study arms concerning dyspepsia-related quality of life, measured by the sum of the subscale scores of the validated Nepean Dyspepsia Index 12 weeks
Secondary The ability of the e-learning to improve knowledge Using a knowledge test integrated in the e-learning and administered before and after the e-learning, the difference in correctly answered questions will be measured 15 minutes
