Objective: To evaluate gastrointestinal risk profiles in patients with osteoarthritis who are currently being treated, or who are candidates for treatment, with a non-steroidal anti-inflammatory drug. Methods: Patients with osteoarthritis treated by primary care physicians or physical and rehabilitation medicine (PRM) specialists in Belgium and Luxembourg were scored for gastrointestinal risk profile, low, moderate or high, based on the presence of gastrointestinal risk factors. These included advanced age, gastrointestinal history, comorbidities, medication use, smoking, and alcohol consumption. Use of gastro-protective agents (proton pump inhibitors) was also assessed. Results: A total of 190 primary care physicians and PRM specialists provided data on 885 patients. A large majority of patients were rated high-risk gastrointestinal (77.8%), with fewer moderate (19.4%) or low (2.8%) risk. The proportion of high-risk patients treated by PRM specialists was significantly lower than that treated by primary care physicians (64.7% vs 79.9%; p
