Abstract
PURPOSE: Upper gastrointestinal (UGI) complications in elderly users of nonselective nonsteroidal anti-inflammatory drugs (ns-NSAIDs) without concomitant use of gastroprotective agents (GPAs) were a leading cause of potentially avoidable drug-related hospital admissions in the Netherlands. We aimed to determine the effectiveness of community pharmacists' interventions to improve safety in ns-NSAID use in patients at UGI risk. METHODS: In this prospective cohort study, pharmacists in participating pharmacies (intervention group, IG) received feedback on drug dispensing in ns-NSAID users of >/=60 years of age at risk for UGI damage and were instructed to select patients to improve ns-NSAID prescribing, in collaboration with primary care physicians. Ns-NSAID users from other pharmacies without concomitant GPA use were followed in parallel as a control group (CG). Changes in the UGI risk of ns-NSAID users between baseline and follow-up measurement, assessed either by the addition of GPAs or the cessation of ns-NSAIDs, were compared between the two study arms. RESULTS: At baseline, 14% of ns-NSAID users at UGI risk did not receive GPAs. Persistent ns-NSAID users from the selected IG patients had an additional 7% likelihood of reduced UGI risk at follow-up (odds ratio 0.93, 95% confidence interval 0.89-0.97) compared with CG patients. In the IG, 91% of selected IG patients at UGI risk from ns-NSAIDs at baseline were no longer at increased risk at follow-up because of cessation of ns-NSAIDS or to concomitant GPA use. CONCLUSION: Although concomitant gastroprotection use in susceptible ns-NSAID users in the Netherlands is high, pharmacist-led interventions could further improve prescribing of ns-NSAIDs.
