I'm sorry if my comment comes at you as if I am a complete numpty who knows nothing...but I have been out of the loop (on medical grounds) for 5 months and haven't seen any letters or AIC's reflecting this change .....so instead of making me feel like I'm an idiot please advise me of a reference detailing the changes. This is the reason for me using the forum....if you can't help me maybe someone more understanding might!
