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).
