Emergency department visits
The majority of patients needed at least one emergency department (ED) visit after their diagnosis, with 60.3% in CHA and 71.4% in CSU-AE. We did not find differences in the overall number of ED visits since the diagnosis. However, significant differences in the number of ED visits within the previous year were found, with a median of one visit in CHA patients and two visits in CSU-AE patients (p= 0.040).
