Mr. Ciar?n Breen:

The reason we do not do that is the possibility of the extraordinary consequences that could arise from it being based on data that is not explained. For example, some hospitals, because of a particular specialty or simply because of the nature of the facility, deal with more difficult cases than others. Some hospitals see particular categories of patients whose cases are more difficult. As a result, outcomes are not readily comparable with those of other hospitals. It is possible to imagine a situation whereby if we were to issue a league table without a major explanation of the data required, some members of the public might say that hospital A is more dangerous than hospital C and that they would never to go to hospital A, and that is not true.
