Limitations
Our study design inherently has selection bias due to intentional sampling. In addition, our study was limited to the Hamilton-Niagara region and may not encompass the experience of more rural Emergency Department settings. Finally, there is a smaller representation among mid-career physicians (6-15 years into practice) compared to those in early or later stages. This may be problematic because this group likely has the most refined practice patterns, and may have been a minority opinion that may have swayed our data one way or another.
