Reversed into a pedestrian

Hi,

Had a bad experience today, I reversed into a pedestrian, but thankfully it wasn't too bad, could have been alot worse.

I reversed into a man, lucky it wasn't a child or eldery person. When I hit him he fell to the ground and sat on the pavement for a while. He stated he was fine, didn't seem angry, refused an ambulance and after a few minutes was up and got on his way. Hopefully he was just winded for a few minutes. I apologised to him and before I left we shook hands so all seems grand.

I'm basically just looking to know is there anything else I should do, or should have done at the time.

Thanks
