It is best to assume that your patients will access their notes, thus best to explain any specific things for them to look for (new test results, reminders, milestones, etc.). Tell them what you are looking for or may expect to find when you order a test, and that they may see the results before you do. The OpenNotes team reports that, in the 10 years of studying the effects of patients reading their notes, clinicians have not reported a significant increase in visit time or emails from patients.
