From what I understand, no one but the HS agency sees that particular dr's form. Now, I suppose if the same dr does the form for your dossier they might connect them, I'm not sure. I'd check with your agency, but I'd think the worst case scenario would be that only your placement agency would need a fixed copy of the HS. USCIS wouldn't have anything to do with it. The 171H doesn't say anything that was in your HS.
It's kinda anticlimatic. There is a box checked saying the approval was cabled to GC and then another box checked stating how many children you are approved for.
I don't think there's much to worry about, but check with the placement agency
