    Abstract:
    OBJECTIVE: To appraise the cost-effectiveness of competing therapeutic strategies in patient cohorts eligible for aspirin prophylaxis with varying degrees of gastrointestinal (GI) and cardiovascular risk. METHODS: Cost-effectiveness and cost-utility analyses were performed to evaluate 3 competing strategies for the management of chronic arthritis: 1) a generic nonselective nonsteroidal antiinflammatory drug (NSAID(NS)) alone; 2) NSAID(NS) plus a proton pump inhibitor (PPI); and 3) a cyclooxygenase 2-selective inhibitor (coxib) alone. Cost estimates were from a third-party payer perspective. The outcomes were incremental cost per ulcer complication avoided and incremental cost per quality-adjusted life year (QALY) gained. Sensitivity analysis was performed to evaluate the impact of varying patient GI risks and aspirin use. RESULTS: In average-risk patients, the NSAID(NS) + PPI strategy costs an incremental 45,350 US dollars per additional ulcer complication avoided and 309,666 US dollars per QALY gained compared with the NSAID(NS) strategy. The coxib strategy was less effective and more expensive than the NSAID(NS) + PPI strategy. Sensitivity analysis revealed that the NSAID(NS) + PPI strategy became the dominant approach in patients at high risk for an NSAID adverse event (i.e., patients taking aspirin with > or =1 risk factor for a GI complication). CONCLUSION: Generic nonselective NSAIDs are most cost-effective in patients at low risk for an adverse event. However, the addition of a PPI to a nonselective NSAID may be the preferred strategy in patients taking aspirin or otherwise at high risk for a GI or cardiovascular adverse event.
