BACKGROUND: Emergency department (ED) overcrowding is a serious issue worldwide. OBJECTIVES: This study was done to evaluate the degree of overcrowding in local “teaching hospitals” in Beijing, and to ascertain the apparent root causes for the pervasive degree of overcrowding in these EDs. METHODS: This is a multicenter cross-sectional study. The studied population included all ED patients from 18 metropolitan teaching hospital EDs in Beijing for calendar years 2013 and 2014. Patient characteristics, and the primary reasons that these patients sought care in these EDs, are described. RESULTS: The total numbers of annual emergency visits were 1,554,387 and 1,615,571 in 2013 and 2014, respectively. High acuity cases accounted for 4.6% and 5.5% of the total annual emergency visits in 2013 and 2014, respectively. The percentage of patients placed into “Observation” beds, which were created to accommodate patients deemed to have problems too complex to be treated in an inpatient bed, or to accommodate patients simply needing chronic care, was 11.9% and 13.1% in 2013 and 2014, respectively. The ED-boarded patients accounted for 2.71% and 2.6% of the total annual emergency visits in 2013 and 2014, respectively. The average waiting time to admit the ED-boarded patients was 37.1 h and 36.2 h in 2013 and 2014, respectively. Respiratory symptoms were the most common presenting complaints, and an upper respiratory infection was the most common ED diagnosis. Patients who had pneumonia or various manifestations of end-stage diseases, such as advanced dementia or multiple organ dysfunction, were the most common characteristics of patients who had stays in “Observation” units. CONCLUSIONS: One principal reason for ED crowding in Beijing lies in the large numbers of patients who persist in the expectation of receiving ongoing care in the ED for minor illnesses. However, as is true in many nations, one of the other most important root causes of ED crowding is “access block,” the inability to promptly move patients deemed by emergency physicians to need inpatient care to an inpatient bed for that care. However, in our system, another challenge, not widely described as a contributor to crowding in other nations, is that doctors assigned to inpatient services have been empowered to refuse to admit patients perceived to have overly “complex” needs. Further, patients with multisystem illnesses or end-stage status, who need ongoing chronic care to manage activities of daily living, have begun to populate Beijing EDs in increasing numbers. This is an issue with various root causes.
