Administrative and clinical information for all NHS Wales Accident and Emergency department attendances. Includes the All Wales Injury Surveillance Systems (AWISS) dataset.

Data recording practices may vary, especially in some of the minor A&E and Minor Injury Units which could account for some local differences.

This dataset requires additional governance approvals from the data provider before data can be provisioned to a SAIL project.

DHCW

Site Code of Treatment (5 character code). The organisation code for the site where the patient will be or is treated.

SITE_CD_OF_TREAT

All data related to the Emergancy Department Data Set:
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.

EDDS

Provider Unit Code (3 character code). This is the organisation code of the health care provider. The provider code identifies the health care provider who is responsible for managing the treatment of the patient.

1.  Healthcare providers may also act as commissioners when sub-contracting patient care services to other providers of health care.

2.  Although the healthcare provider identified in this data item is responsible for managing the patient’s treatment, it may not necessarily be where the treatment is actually conducted. For example, where the treatment has been sub-contracted to another healthcare provider.

3.  For OPRD (outpatient referral dataset), the Organisation Code (Code of Provider) is that of the organisation receiving the referral. If the provider is a Local Health Board/Trust, use the 3 character Local Health Board/Trust code with 2 zeros placed in the 4th and 5th character position.

4.  For RTTD (Referral to Treatment Times (Combined)), use the 3 character Local Health Board/Trust code.
