Development of Patient Education Material for Proton Pump Inhibitor Deprescribing: A Mixed-Methods Study.

Background: Proton pump inhibitor (PPI) deprescribing is recommended in case of inappropriate use. Patient education materials are key elements in the deprescribing process.

Objective: The study objective was to develop patient education material for PPI deprescribing in primary care in France.

Methods: This was a mixed-methods study involving (1) a literature review of the existing patient education materials on PPI deprescribing to identify key points to optimize the layout and content of the document; (2) development of a first version of the brochure by a pluri-professional steering group, following the national reference methodology of the French National Authority for Health (Haute Autorité de Santé) and iterative modifications of the patient brochure; (3) assessment of the content and understandability of the brochure by questionnaires followed by semistructured interviews with target patients; and (4) iterative brochure readability assessment with the Flesch reading ease tool.

Results: The final patient education material is a double-sided A3 brochure-that is, 4 A4 pages. The first round of user testing by questionnaire (n = 14 patients) led to modifications to improve the document understandability, validated in the second round of user testing by questionnaire (n = 10 patients). The semistructured interviews (n = 10 patients) highlighted an adequate comprehension, whereas actionability required some minor modifications. The readability test score of the final education brochure was 59.4.

Conclusion and relevance: This patient education brochure for PPI deprescribing is targeted to patients in primary care. Its impact on PPI deprescribing will be assessed in a population-based pragmatic trial in primary care.
