p values for the comparisons between the two groups are reported. Data are reported with mean and standard deviation or with median and interquartile range for continuous variables. Categorical variables are expressed with counts and percentages. Triage Code: 1 Lack of consciousness, highly unstable vital parameters. Need of immediate life-saving intervention; 2 = Unstable vital parameters; 3 = Stable vital parameters, but multiple resources need to stabilize the patient. Deferable urgency cases. 4 = Minor emergencies. One resource needed to stabilize the patient. 5 = non-urgent cases. No resources needed to stabilize the patient. Exit Code: 1 = Coma, shock, highly unstable hemodynamics or breath despite intensive cares in the emergency department; 2 = Unstable vital parameters; 3 = Stable vital parameters; 4 = Minor emergencies; 5 = Nonurgent cases.
