Yes, that is correct. I made the changes, (only minor adjustment to your solution was that I had to replace a 'default' with 'patient_scan_history' when setting response.js).
As usual, while writing my post I became slightly clearer in my head about where the problem lay, but didn't have the confidence to try anything until I heard back from this forum. During my searches, I found this helpful vimeo by 'mdipierro', which is related to your solution... http://vimeo.com/21363988 Thanks to all those who helped, I understand this a lot more now.
