To take part in LiTEFORM there are some criteria that you need to meet. These can be found here. 

Your doctor(s) will decide if you can take part or not. If they think you would be suitable, they will give you an information sheet to read and consider in your own time. You will be given at least two days to consider taking part and you can talk to your friends and family about it.

There are several hospitals in the England and Wales taking part in LiTEFORM. A full list of trial hospitals can be found here.
