Time-trends in gastroprotection with nonsteroidal anti-inflammatory drugs (NSAIDs).

BACKGROUND: Preventive strategies are advocated in patients at risk of upper-gastrointestinal complications associated with nonsteroidal anti-inflammatory drugs (NSAIDs). AIM: To examine time-trends in preventive strategies.
METHODS: In a study population comprising 50 126 NSAID users > or =50 years from the Integrated Primary Care Information database, we considered two preventive strategies: co-prescription of gastroprotective agents and prescription of a cyclooxygenase-2-selective inhibitor. In patients with > or =1 risk factor (history of upper-gastrointestinal bleeding/ulceration, age >65 years, use of anticoagulants, aspirin, or corticosteroids), correct prescription was defined as the presence of a preventive strategy and under-prescription as the absence of one. In patients with no risk factors, correct prescription was defined as the lack of a preventive strategy, and over-prescription as the presence of one.
RESULTS: Correct prescription rose from 6.9% in 1996 to 39.4% in 2006 (P < 0.01) in high-risk NSAID users. Under-prescription fell from 93.1% to 59.9% (P < 0.01). In the complete cohort, over-prescription rose from 2.9% to 12.3% (P < 0.01).
CONCLUSIONS: Under-prescription of preventive strategies has steadily decreased between 1996 and 2006; however, 60% of NSAID users at increased risk of NSAID complications still do not receive adequate protection.
