Introduction of a horizontal and vertical split flow model of emergency department patients as a response to overcrowding

Author(s): Wallingford, G., Joshi, N., Callagy, P., Stone, J., Brown, I., Shen, S.
Hospital emergency departments (EDs) strive to optimally organize patient flow so that optimal care can be delivered while patient length of stay is minimized. The emergency severity index (ESI) is a 5-point scale used to help medical staff discern the severity of patient conditions; higher ESI scores indicate less-severe medical conditions.

The effect of vertical split-flow patient management on emergency department throughput and efficiency

Author(s): Garrett, J. S., Berry, C., Wong, H., Qin, H., Kline, J. A.
In some emergency departments (EDs), the severity of a patient’s condition is rated on a 5-point scale during admission using the Emergency Service Index (ESI). Under the “split-flow” model of patient triaging, patients with less-severe conditions (rated an ESI 4 or 5) are “fast tracked” so that they can be separated from patients with higher ESI scores, allowing for more efficient resource allocation for all patient treatment procedures.

Separate Medication Preparation Rooms Reduce Interruptions and Medication Errors in the Hospital Setting: A Prospective Observational Study

Author(s): Huckels-Baumgart, S., Baumgart, A., Buschmann, U., Schüpfer, G., Manser, T.
Errors and interruptions are commonplace during medication preparation procedures in healthcare environments. One study found that one interruption occurred for every 3.2 drugs administered during nurses’ medication rounds.

Route complexity and simulated physical ageing negatively influence wayfinding

Author(s): Zijlstra, E., Hagedoorn, M., Krijnen, W. P., van der Schans, C. P., Mobach, M. P.
In this study, “wayfinding” is defined as determining and following a path or route between an origin and a destination. Wayfinding can be particularly difficult in complex and sometimes stressful environments like hospitals, and as hospitals continue to expand to meet increasing healthcare demands, their layouts face the possibility of becoming more difficult to navigate. Wayfinding is particularly difficult for the elderly, who may have memory issues and weakened physical abilities. Support from the environment is necessary to help elderly people function at their best, so it is important to understand what elements of the designed environment either benefit or confuse them.
