PurposeWaiting is a common experience for patients during an emergency department (ED) visit. While high acuity patients are seen with little delay, low acuity patients may experience dissatisfaction from prolonged wait times. One strategy to improve patient experience involves changing the perception of the wait by providing realistic expectations of wait times using public-facing wait time displays. The primary objective of this study is to quantify the number of Canadian EDs with online wait time displays and describe the features and type of information provided.MethodsA systematic online search of all Canadian EDs was completed to identify EDs with public-facing wait time displays. A scoping review was then performed to assess their message characteristics, translations offered, availability of multi-site information, and accessibility features. Data were summarized using descriptive statistics.ResultsSixty (9.3%) of the 647 Canadian EDs identified provide public-facing real-time wait time displays. Thirteen of these (21.7%) were associated with a single proprietary system. Distribution of wait time displays differs across Canada, with a range of zero to 100% of EDs within each province utilizing this communication tool. Common characteristics include "average" wait time (95%), graphical trend data (32%), number of patients waiting (33%), longest wait time (12%), and expected length of stay (10%). Sixty-two percent of wait time displays provide a combination of these methods to inform wait times. Important accessibility features include language translation, compliance with Canadian National Institute for the Blind (CNIB) accessibility guidelines and availability on a mobile application.ConclusionCurrently, there is emerging use of wait time displays in Canada with considerable variability in the information communicated through these tools. Effectiveness of these displays and their content needs to be determined.© 2022.
