Part of COSD pathology user guide v4.1.1

CORE

Core chapter on data linkage as part of the pathology user guide version 4.1.1

These items are Mandatory for every record in order to link patient records.

In order to ensure that records submitted can be linked appropriately some key data fields must be completed for each record submitted. These are shown in the Core Linkage section.

There will be one linkage section completed each time the record is submitted.

Note: it is important to refer to the Pathology User Guide if reporting pathology direct from the LIMS as there are different linkage items required.


Linkage

These items are Mandatory for every record in order to link patient records.

In order to ensure that records submitted can be linked appropriately some key data fields must be completed for each record submitted. These are shown in the Core Linkage section.

There will be one linkage section completed each time the record is submitted.


Patient Identity Details

One of the following Core Linkage Identifier sections must be provided per record (1..1)

A combination of either ‘NHS Number’ and/or ‘Local Patient Identifier’ are mandatory for the schema. Both can be submitted, but a record cannot be submitted without at least one of these data items.

NHS Number

The ‘NHS Number’ is a unique identifier for a patient within the NHS in England and Wales. This will not vary between any organisations of which a person is a patient.

Local Patient Identifier

For linkage purposes, ‘NHS Number’ and/or ‘Local Patient Identifier’ are required. This is a number used to identify a patient uniquely within a health care provider. It may be different from the patient's case note number and may be assigned automatically by the computer system.


NHS Number Status Indicator Code

The ‘NHS Number Status Indicator Code’ indicates the verification status of the NHS number provided.

National Code

National code definition

01

Number present and verified

02

Number present but not traced

03

Trace required

04

Trace attempted – No match or multiple match found

05

Trace needs to be resolved – (NHS Number or patient detail conflict)

06

Trace in progress

07

Number not present and trace not required

08

Trace postponed (baby under 6 weeks old)

Person Birth Date

The date on which a person was born or is officially deemed to have been born. This should be automatically linked via your local PAS system when you create a record for the first time.

Note:

  • this is now a mandatory data item from v4.0

Organisation Identifier (Code of Provider)

The ‘Organisation Identifier’ of the organisation acting as a health care provider (an6 not applicable to COSD). This is the 3 or 5-digit code of the organisation submitting the demographic details. This will therefore normally be either the organisation where the referral is received or the treating organisation.

Notes:

  • there is a new code structure (ANANA) for new organisation identifiers allocated by ODS from 01 September 2020 onwards - codes issued prior to this date will not be converted
  • find more details about ODS codes on the NHS Digital website.

Demographic Details

Demographic details are required for every record in order to ensure that the correct patient can be identified, and information can be correctly linked. The Demographics section should be completed by every Provider the first time a record is submitted.

There will only be one Demographics section completed for each record. Demographic linkage items will be required each time the record is submitted. Almost all patients should have an NHS Number and this should always be included where available. For those who do not have an NHS Number, the hospital number 'Local Patient Identifier' must be provided.

It is anticipated that some of the demographic data items listed below will be collected by every provider with which the patient has contact. Where this information is exchanged, the appropriate data item name should be used.

May be up to one occurrence per record (0..1)
