Are written responses to some referrals to a general haematology clinic acceptable?

We inadvertently transposed elements of the title of a paper by Tso and colleagues (23 October, pp 946-7), which changed the meaning entirely, after the authors had seen the proofs. The study considered whether written referrals from a haematology clinic were acceptable to general practitioners and patients, not whether they were acceptable to the haematology clinic (as implied by the originally printed title, “Acceptability to a general haematology clinic of written responses to referrals”). The correct title is “Are written responses to some referrals to a general haematology clinic acceptable?” We have corrected this on bmj.com.
