Discharge against medical advice (DAMA) may put patients at risk of adverse health outcomes and often generate hospital readmission. A retrospective case-control study (2000-2004) of all DAMA in Veneto Region hospitals was carried out to determine the baseline characteristics of patients who leaves hospital. During the 5-years study period, the overall DAMA rates were 0.8 from ordinary hospitalization and 0.2 from daily. Prediction of patients at risk of DAMA may be possible with several defined variables and this analysis represent an instrument that should facilitate the development of successful strategies to reduce DAMA for high-risk patients.

New technologies in these years has taken to a spread and to a growth of the CT application with an increase of patients and population exposure. In clinical practice some technical devices can be used to reduce the exposure dose of multidetector CT that allows radiologist to answer the clinical question with less damage to the patient. The radiologist remains however the guarantor of the ionizing radiation exposition and he has to consider also the opportunity to use other methodics (MR, US) to answer some questions. The radiologist has the role to evaluate the clinical indication to the exam demanded from other doctor and has the responsibility for exam management and for progressive radiologic course, controls and follow-up.
