Abstract
BACKGROUND: Overcrowding decreases quality of care. Triage and patient administration are possible bottlenecks. We aimed to identify factors influencing door-to-triage- and triage-to-patient administration-time in a prospective observational study at a tertiary care center with 70,000 patients per year. METHODS: Measurement of aforementioned times at convenience-sampled time intervals on 16 days. Linear regression modelling with times as dependent variable, and demographic, medical and structural factors as covariables, testing for interactions with risk factor "weekend". RESULTS: We included 360 patients (183 female (51%)). Median door-to-triage-time was 6 (IQR 3-11) minutes, triage-to-patient administration-time was 5 (IQR 3-8) minutes. Overall door-to-triage-time was significantly shorter during weekends compared to weekdays (absolute difference 3 (IQR 1-7) minutes; 5 (IQR 3-8) vs. 8 (IQR 4-15) minutes, p < 0.01). Other influencing factors were closing hours of non-emergency department healthcare facilities (3.5 min more), number of ESI 2 patients seen during the interval (3 min more for each patient per hour), and ambulance activity (2 min more for each patient per hour brought by ambulance). CONCLUSIONS: Day of time and week as well as frequency of patients with urgent conditions and those brought by ambulance significantly increased door-to-triage times. This should be kept in mind when organizing ED workflow.
