Study design details

Main study objective

Our aims were to describe the incidence of haemorrhages and adversedrug events (ADEs) related to different classes of drugs as cause of ED admission, the characteristics of patients, the kind of bleeding and thedescription of hospitalizations and intra-hospital deaths.

Outcomes

To estimate the incidence of hemorrhagic patients entering theemergency department during the study period

Data analysis plan

To estimate the incidence of hemorrhagic patients entering theemergency department during the study period we calculated the ratiobetween the patients with an ICD-9 DM diagnosis that code for ahaemorrhage respect to all patients who entered in the same period.Descriptive baseline characteristics were expressed in percentages andmeans ± standard deviation of the mean. Data about hemorrhage anddrugs are presented as percentage since they are categorical variables.
