For activity from 2011-12 onwards, HES users are advised to use the field CURRWARD_ONS instead of CURRWARD. This field, which is derived from the patient's postcode in the field HOMEADD, contains a code which defines the pre-2011 electoral ward of the patient. Note that this field uses old-style geographical codes that were superseded in 2011 and are now no longer supported by ONS - the new style code can be found in the field CURRWARD_ONS. Because identical CURRWARD codes are allocated to many local authority districts, CURRWARD is meaningless in isolation. This field should be used in conjunction with RESLADST (local authority district) to produce a unique value indicating the ward within a given district where the patient resided.|For activity from 2011-12 onwards, HES users are advised to use the field CURRWARD_ONS instead of CURRWARD.
