Users of hospital emergency department who are discharged home
The overall aim of the studies was to determine characteristics and prognosis of Emergency Department users, who were discharged home. The specific aims were to record the annual number of discharged users of the ED according to age and gender, their annual number of visits and to assess whether a h...

The specific aims were to record the annual number of discharged users of the ED according to age and gender, their annual number of visits and to assess whether a higher frequency of visits predicted higher mortality; to describe the pattern of discharged diagnoses; to evaluate the association of non-causative diagnoses with mortality in general, and in particular with external causes of death, drug intoxication and suicide; to evaluate risk factors for suicide and fatal drug poisoning; to evaluate the association between death within eight days after discharge home from the ED and non-causative discharge diagnoses.
