The dates when a patient listing status changes need to be recorded. A patient's classification may change if he or she is examined by a clinician during the waiting period, i.e. undergoes clinical review. The need for clinical review varies with the patient's condition and is therefore at the discretion of the treating clinician. The waiting list information system should be able to record dates when the classification is changed (metadata item Category reassignment date).
At the Waiting Times Working Group meeting on 9 September 1996, it was agreed to separate the metadata items Patient listing status, readiness for care and Clinical urgency as the combination of these items had led to confusion.
