The Emergency Department Data Set (EDDS) captures attendances at Accident & Emergency departments and Minor Injury Units (MIUs) in Welsh hospitals.
Velindre NHS Trust does not provide EDDS data as there are no A&E departments or MIUs in the Trust.
Welsh residents who attended an emergency department in England are not included.
The submission is based on administrative end date.
Planned follow up patients are included.
Definitions that apply to SITREPS may differ from those associated to the EDDS.
