ABSTRACT: Objective
Inflammatory bowel disease (IBD) is a chronic, autoimmune, gastrointestinal disorder. Canada has one of the highest prevalence and incidence rates of IBD in the world. Diagnosis is challenging due to the similarity of symptoms to functional gastrointestinal disorders. Faecalcalprotectin (FC) is a biomarker for active mucosal inflammation and has proven effective in the diagnosis of IBD. Our study objective was to assess the cost-effectiveness of adding an FC test compared with standard practice (blood test) in primary care among adult patients presenting with gastrointestinal symptoms.Design
We constructed a decision analytic tree with a 1-year time horizon. The cut-off level of 100?µg/g was used for FC testing. Probabilistic analyses were conducted for the base case and all scenarios.Setting
Canadian health sector perspective.Population
A hypothetical cohort of adult patients presenting with gastrointestinal symptoms in the primary care setting.Interventions
FC test compared with blood test.Main outcome measures
Costs, quality-adjusted life years (QALYs), incremental cost-effectiveness ratio (ICER) of FC test expressed as cost per QALY gained compared with blood test and time to IBD diagnosis.Results
FC testing is expected to cost more ($C295.1 vs $C273.9) than standard practice but yield little higher QALY (0.751vs0.750). The ICER of FC test was $C20?323 per QALY. Probabilistic analysis demonstrated that at a willingness-to-pay threshold of $C50?000 per QALY, there was 81.3% probability of FC test being cost-effective. The use of FC test in primary care reduced the time to IBD diagnosis by 40.0 days (95% CI 16.3 to 65.3 days), compared with blood testing alone.Conclusions
Based on this analysis of short-term outcomes, screening adult patients in primary care using FC test at a cut-off level of 100?µg/g is expected to be cost-effective in Canada.
