If a patient is treated on a date after their 18 Week RTT date was due, this is classed as a ‘breach’ of the standards. It is really important to know that a patient does not breach until they are treated e.g. if a patient is referred to Hospital on 1.2.2013 the date they must be treated by is 7.6.2013 if the patient is treated after this date they will breach in the month that they are treated.
