Patient Identification errors has been set as the issue to tackle. The impact of «mistakes» in the Radiology Department could lead to investigate or administrate a procedure with exposure to irradiation, and the reporting of a pathology affects severely the following treatment to wrong patients.

Overall, the project increased patient safety, supported workflow simplification and efficiency and the whole organization took benefit from it. Sharing results with the staff of the Department at each project step, it has been fundamental to have them involved and proactive.
