Cost Comparison of CCTA Vs. Catheterization

Article:
The study modeled the costs of two clinical approaches: 1) immediate catheterization for all patients in the group; and 2) selective catheterization, based on the results of CT scanning. Costs were analyzed based on actual reimbursements from insurers (Medicare and private insurance) for these procedures.

Summary:
The study found that using CCTA as a gate-keeper for catheterization reduces costs by $1,454, a savings of nearly 50%. The results held true within a wide range of assumptions—when higher costs for scanning are assumed, and/or lower costs for catheterization, and/or more patients going on to catheterization than the study shows, large cost savings still result. Furthermore, it is unlikely that the cost savingswould be undermined by over-use of scanning. The researchers concluded that even if some patients who would have received medical management rather than catheterization end up getting scanned, the overall savings would still be substantial, because so much is saved by reducing catheterizations.

The study did not focus on outcomes, but there were indications in this area: 1) scanning is highly accurate when there are negative results— approaching 100% accuracy according to the study; 2) the study indicates that scanning can reduce complications and morbidity relative to catheterization, because it is less invasive. The researcher’s state, based on these results, CCTA should be incorporated into clinical practice.
