Impact analysis of expanding anti-TNF therapy for Crohn’s disease

Abstract

Aim: To estimate the impact of universal anti-TNF therapy in patients with moderate-to-severe Crohn’s disease. Materials & methods: Developed a population-level Markov model to estimate the impact on health outcomes and medical expenditures of expanding anti-TNF therapy use versus current treatment practices. Results: Reductions in deaths (2600), hip fractures (980), major adverse cardiac events (2700) and patient out-of-pocket medical spending (2%) over 5 years. Total societal costs would be US$22,100 higher per patient per year, primarily due to the high cost of anti-TNF therapy. Conclusion: Expanding anti-TNF therapy use among US adult patients with moderate-to-severe Crohn’s disease would reduce morbidity and mortality, decrease disease-related medical costs and increase treatment costs compared with current practice. Despite the higher costs, this approach could substantially benefit patients.
