Obphuscator2, the losses were for Jan-June last year.
NICE only indicated a preliminary preference for BtB in May.
There are now at least 74 PCTs offering BtB (and sometimes more Ult products).
NICE will rubber stamp its recommendation for BtB in Feb (this was due in Nov but there was an appeal against a product in different class of treatment which held up the entire process.)
A NICE recommendation has to be actioned by PCTs within 3 months of publication.
