Abstract
As of 2014, over 75% of primary care physicians in Ontario have adopted,¹ or are in the process of adopting an EMR. Those physicians who are new to using EMR will find many pitfalls, many of which are common and are preventable. I will specifically deal with the OSCAR McMASTER EMR and what issues I saw my fellow colleagues and myself experience in the Ontario context.
