Inappropriateness of breast imaging: cost analysis.

PURPOSE

The aim of this study was to assess how an incorrect indication for an examination may affect the diagnostic workup and diagnosis as well as healthcare expenditure.

MATERIALS AND METHODS

We considered all the requests for breast imaging (mammography, ultrasound and magnetic resonance imaging) received by our radiology department between October 2010 and December 2010, and assessed their appropriateness based on the patient's age and the clinical question, if present. We then analysed the unnecessary costs resulting from inappropriate requests.

RESULTS

Out of a total of 1500 requests for ultrasound examination, the request was appropriate in 855 (57%) cases; out of a total of 2350 requests for mammography, the request was appropriate in 493 (21%) cases; out of a total of 100 requests for magnetic resonance imaging, the request was appropriate in 83 (83%) cases. The cost deriving from inappropriate requests was 51,235.04 Euros.

CONCLUSIONS

Improving the timeliness of diagnosis is an important goal to be pursued by enhancing the available health services, improving communication and coordination of the different professionals involved and optimising diagnostic pathways in order to reduce healthcare spending.
