NAME ^

Medical::NHSNumber - Check if an NHS number is valid

VERSION ^

Version 0.04

SYNOPSIS ^

Everyone registered with the NHS in England and Wales has their own unique NHS number. The NHS number enables health care professionals in the UK to obtain, link and index electronic health records for an individual across a multiple sources of clinical information.

Given a new-style NHS number, returns true if the number is valid and false if the number appears to be invalid.

    use Medical::NHSNumber;

    my $nhs_no = '1234561234';
    my $rv = Medical::NHSNumber::is_valid( $nhs_no );

The validation is performed using the Modulus 11 algorith. More details on the exact implementation followed can be found on the NHS Connecting for Health website at http://www.connectingforhealth.nhs.uk/industry/docs/pds/index.html?dat_nhs_no.htm

Additional information on Modulus 11 can also be found on this HP site http://docs.hp.com/en/32209-90024/apds02.html

Please note, this module will only check the validity of new style NHS numbers i.e. ten digit numbers. There are over 21 different formats for older styles of NHS numbers which currently, this module does not support. If you do happen to know the specifics for the older versions and would like to tell me, I would be more than happy to incorporate some logic for them.

FUNCTIONS ^
