nn

Number present and traced using Welsh NHS AR

Welsh LHB's should look for high levels of NHS numbers which have an associated status indicator value of 'nn'.

1^st April 1999

01

Number present & traced

Providers should be striving to submit numbers that have been traced against an authoritative source (currently the Initial Tracing Service) and so are as reliable and accurate as possible. Therefore Local Health Boards should look for high levels of NHS numbers which have an associated status indicator value of "01".

1^st April 1999

02

Number present but not traced

This value reveals that although a number is present, it has not been traced against an authoritative source i.e. it has most likely been manually input but not sent to the Initial Tracing Service for checking. An exception to this could be that the NHS number has entered the provider system electronically from a reliable and safe source other than the authoritative tracing service. Users of NHS numbers with a status indicator value of "02" should be cautious.

1^st April 1999

03

Trace required

The provider should submit patient details for NHS number tracing before DS's are submitted. Therefore the proportion of missing numbers is indicated by the "03" value should be very small.

1^st April 1999

04

Trace attempted – no match or multiple match found

A significant proportion of "04s" could indicate data quality problems at the provider. However, the LHB should take account of whether the provider has a high level of difficulty to trace patient’s e.g. ethnic names, mobile population.

1^st April 1999

05

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

High levels of "05s" imply that the NHS numbers sent by the provider for check tracking are incorrect for the patient. This indicates poor quality of data which could either be due to a poor original source e.g. wrong number given on a GP referral letter, or poor data input by the provider.

1^st April 1999

06

Trace in progress

This value indicates that the NHS number has been submitted for tracing but a response is awaited. Local Health Boards should expect to see a small proportion of these as the time of DS submission may be before the response from the tracing service is received.

1^st April 1999

07

Number not present and trace not required

Two circumstances are explained by this indicator:

1^st April 1999

1.

NHS number is not required e.g. overseas visitor. This should be easy to identify from other DS data items

2.

There is insufficient patient data to enable a successful trace to be made. Local Health Boards need to be more cautious about this reason although they should take into account the type of population the provider serves e.g. itinerants and mental health patients who may not be willing or able to provide sufficient information.

Note: Local Health Boards should expect to see a small proportion of cases where there is no NHS number at all.

08

Trace postponed (baby under six weeks old)

This indicator should only be used for babies under six weeks old and Local Health Boards should check the date of birth details on the DS.
