Optimization of the Prescription of Gastric Acid Blockers – DROPIT Study: a Randomized Clinical Study in an Outpatient Setting
Zusammenfassung der Studie
In this study, 80 general practitioners and a total of 400 participants will be included. The study participants are adults who have been prescribed gastric acid blockers without reason for a long time or in too high a dosage. Additionally, there must be no additional risk factors to consider. The general practitioners and participants will be randomly assigned to an experimental group and a control group. The experimental group will receive a guideline for the optimal prescription of gastric acid blockers for the included participants, while the participants in the control group will continue to be treated as usual by their general practitioner. The participants will not know which group they have been assigned to (blinded study). The study lasts 12 months. Every 3 months, online questionnaires will be sent to the general practitioners and participants, collecting data on medications, diagnoses, quality of life, and use of medical infrastructure, e.g., number of hospitalizations. Already during the study and also at the end of the study, we will compare the change in prescriptions of gastric acid blockers between the two groups (control group and experimental group). We will also take care of the safety of all participants and check that the optimization guideline does not lead to any uncertainties or dangerous situations. Finally, we will also compare the costs of the two groups and gather the opinions of all participants regarding the study. The collected data will be analyzed anonymously and the study results will subsequently be published in specialized journals.

Untersuchte Intervention
In this study, the general practitioners will be randomly assigned to a control group or an experimental group. The experimental group will receive a guideline for the optimal prescription of gastric acid blockers for the included participants, while the participants in the control group will continue to be treated as usual by their general practitioner.
This guideline will be developed by the study team before the start of the study. The intervention will include a clearly structured guideline for reviewing the medications of the participants and will guide the general practitioner and the participants through an algorithm that will help them better decide whether it makes sense in individual cases to continue prescribing the gastric acid blocker, reduce it, or even stop it altogether. The decision criteria for adjusting the prescription are based on safe, sustainable, and evidence-based knowledge and will be developed in collaboration with experts, general practitioners, and patients.

This study does not investigate any disease, but rather a guideline for the use of gastric acid blockers. Gastric acid blockers, also known as stomach protectors, are medications that reduce gastric acid. These medications are usually taken as tablets, typically once daily in the morning before meals. The indications for gastric acid blockers are very diverse and range from acid reflux (reflux), as an accompanying medication in pain therapy, to treatment for a known gastric ulcer or after a gastric bleed. Participants in the study are individuals who have been taking a gastric acid blocker for a very long time or at a high dosage. Gastric acid blockers reduce acid production in the stomach and thereby alleviate symptoms. Normally, this medication is discontinued after 8 to 12 weeks. However, it can happen that these are forgotten and remain on the medication list or are simply continued at too high a dosage. This is referred to as inappropriate gastric acid blockers. Like other medications, gastric acid blockers can lead to side effects, e.g., vitamin B12 deficiency, calcium deficiency, an increased risk of bone fractures and infections, etc. Therefore, it is of great interest to verify whether their benefit still exists with long-term use. In some cases, it may be advisable to reduce the dose, stop completely, or use the gastric acid blocker only as needed. This is precisely why we are developing a guideline for general practitioners, which is intended to help evaluate and optimize the use of gastric acid blockers. Our study aims to examine the benefits of using this guideline to optimize the prescription of gastric acid blockers.
