If there are accurate data available, this is a fairly simple study to conduct. You measure the before EHR and after EHR statistics and see if there is an improvement. What is the catch in this research though is that the pre-intervention data is not really available. Therefore, a retrospective study is not possible. Rather, starting data would need to be collected, which would mean asking patients their sexual identity before the implementation of the EHR changes. This is not impossible or even terribly difficult, but it requires a high level of commitment. As many patients as possible would need to be asked about their status but not using the EHR. A pilot study in a smaller primary care office or practice group might be the best way
