Capsule endoscopy in suspected small bowel Crohn's disease: Economic impact of disease diagnosis and treatment

AIM: To model clinical and economic benefits of capsule endoscopy (CE) compared to ileo-colonoscopy and small bowel follow-through (SBFT) for evaluation of suspected Crohn's disease (CD).METHODS: Using decision analytic modeling, total and yearly costs of diagnostic work-up for suspected CD were calculated, including procedure-related adverse events,hospitalizations, office visits, and medications. The model compared CE to SBFT following ileo-colonoscopy and secondarily compared CE to SBFT for initial evaluation.RESULTS: Aggregate charges for newly diagnosed,medically managed patients are approximately $8295.Patients requiring aggressive medical management costs are $29 508; requiring hospitalization, $49 074.At sensitivity > 98.7% and specificity of > 86.4%, CE is less costly than SBFT.CONCLUSION: Costs of CE for diagnostic evaluation of suspected CD is comparable to SBFT and may be used immediately following ileo-colonoscopy.
