[Quality of the documents requesting and reporting CT scans: a retrospective study in four Italian hospitals].

: A retrospective study was performed to evaluate the quality of CT scan request and report forms in four Italian hospitals in three different Regions. A sample of 800 request forms and corresponding reports in four hospitals were evaluated. Half of the analysed reports involved inpatients while the other half involved outpatients. The four participating hospitals were all of different typology. Study results show that the request forms do not always contain important information such as the suspected diagnosis or name of the requesting physician. Quality indicators of the examined documents were evaluated in relation to their impact on clinical safety.
