I am looking to send out an email based on a patient's discharge where PID13-4 contains their email. We are currently using something similar with an Email.OutboundAdapter. However, in our current scenario we have a hard coded email in place as the recipient (as this is for order notification to a pager). In the scenario in question, I would need PID13-4 to populate as the recipient of the email. Does anyone have an example of something similar, or a suggestion on where to start?
