Background: Patients with osteoarthritis (OA), rheumatoid arthritis (RA), or ankylosing spondylitis (AS) are commonly treated with nonsteroidal anti-inflammatory drugs (NSAIDs), sometimes with a concomitant gastroprotective proton pump inhibitor (PPI). The present study examines real-life patient adherence to PPIs when coprescribed with NSAIDs. Methods: This retrospective medical record survey identified patients diagnosed with OA, RA, or AS who had PPIs coprescribed with NSAIDs for prevention of NSAID-associated gastrointestinal ulcers. Actual NSAID and PPI intake was retrospectively recorded using a self-reported questionnaire. Adherence to PPI treatment was assessed using descriptive statistics. Results: In total, 96 patients (69% female, mean age 67 years, 72% OA, 16% RA, 12% AS) were included. The mean patient-reported adherence to coprescribed PPIs was 73%–81%. The percentage of patients with a self-reported adherence of ≤80% was 26%. No predictive factors for low adherence could be identified. Conclusion: Despite doctors’ instructions to use PPIs concomitantly with NSAIDs, the mean patient-reported adherence to coprescribed PPIs in this population indicates a risk of a “gastroprotective treatment gap”. The patients’ adherence to gastroprotective PPIs for the prevention of NSAID-associated upper gastrointestinal ulcers can be improved.
