Abstract
BACKGROUND: Crowding in emergency departments (ED) has a negative impact on quality of care and can be averted by allocating additional resources based on predictive crowding models. However, there is a lack in effective external overall predictors, particularly those representing public activity. OBJECTIVES: This study, therefore, examines public activity measured by regional road traffic flow as an external predictor of ED crowding in an urban hospital. METHODS: Seasonal autoregressive cross-validated models (SARIMA) were compared with respect to their forecasting error on ED crowding data. RESULTS: It could be shown that inclusion of inflowing road traffic into a SARIMA model effectively improved prediction errors. CONCLUSION: The results provide evidence that circadian patterns of medical emergencies are connected to human activity levels in the region and could be captured by public monitoring of traffic flow. In order to corroborate this model, data from further years and additional regions need to be considered. It would also be interesting to study public activity by additional variables.
