Reports will show median results and ranges of reported results for each of these parameters. However, performance analysis will only be carried out on CT or R values respectively, as described below.
Survey results are analysed and a median (target) value determined. The results are arranged in order and a target range is calculated whereby the 20% of centres that are farthest away from the median (10% above and the 10% below) are considered to be outwith consensus. The centres within the target range are within consensus.
Participants' results and performance details are kept in confidence between UK NEQAS BC and the named individuals identified by the participant. If results are outwith consensus in 3 consecutive surveys a letter will be sent from the Scheme Director bringing attention to this and offering assistance.
