Notes:
For Elective Admission List CDSs, this date is derived from OFFERED FOR ADMISSION DATE and ADMISSION OFFER OUTCOME and is needed to meet central requirements. It is recorded when PATIENTS who have been offered a date for admission have missed this admission date with or without advance notice.

For Out-Patient Attendance CDS, the four dates, REFERRAL REQUEST RECEIVED DATE, APPOINTMENT DATE, ATTENDANCE DATE and LAST DNA OR PATIENT CANCELLED DATE, together provide all the information needed to derive the out-patient waiting time for the QM08 return. Both APPOINTMENT DATE and ATTENDANCE DATE may be required to calculate waiting times if the PATIENT cancels an appointment or did not attend and then subsequently attended at a future date.
