AIM: To evaluate the economic impact of celecoxib therapy vs. diclofenac plus omeprazole therapy for the treatment of arthritis in Chinese patients with a high risk of bleeding, from the perspective of a public health organization in Hong Kong. METHODS: The medical records of 287 Chinese arthritic patients with a history of bleeding ulcers who had previously participated in a randomised study of celecoxib 200 mg twice daily and extended-release diclofenac 75 mg twice daily plus 20 mg of omeprazole daily for 6 months were reviewed. RESULTS: Compared to the diclofenac plus omeprazole group, the average total direct cost per patient in the celecoxib group showed a significant reduction of 11%, from HK 10,915 (range HK dollars 10,915-57,899) to HK dollars 9714 (range HK dollars 9714-89,770) (P<0.0001) (1 US dollars=7.8 HK dollars). The median direct medical cost for routine management in the celecoxib group was significantly lower (11%) than that for the diclofenac plus omeprazole group [HK dollars 10,915 (range 10,915-28,048) vs. HK dollars 9714 (range HK dollars 6946-26,179) (P<0.0001)]. In patients who experienced recurrent bleeding, the celecoxib group showed a significantly higher median cost of management of recurrent bleeding than the diclofenac plus omeprazole group [HK dollars 8466 (range 572-29,851) vs. HK dollars 23,210 (range HK dollars 12,318-65,823)] (P=0.036). CONCLUSIONS: Celecoxib therapy appears to cost less compared with diclofenac plus omeprazole for treatment of arthritis in Chinese patients with a high risk of bleeding.
