The economics of PillCam.

Evaluation of the economics of PillCam technology is in its infancy. Most studies of the use of the PillCam, both small bowel and esophageal, have focused only on the capsules' diagnostic characteristics. Although the results have compared favorably with other more invasive and sometimes less accurate modalities, the true cost effectiveness of PillCam is not yet fully known. The few cost-effectiveness assessments performed suggest that PillCam compares favorably with traditional diagnostic methods in Crohn's disease and in screening for complications of GERD and for esophageal varices. The data included in these models are quite limited, however. Sensitivity analyses can permit assessment of a wide range of possibilities regarding cost and diagnostic efficacy. Still, these models need to be anchored by robust and reproducible data input. Large-scale studies with long-term follow-up are needed. Capture of both direct and indirect medical costs accrued by using PillCam or other diagnostic tests in these studies will permit more robust economic analyses. As data accrue,they may give clinicians more confidence that PillCam use will realize economic savings and improve patient outcomes.
