National Chlamydia Screening Programme
Chlamydia testing and diagnoses in 15-24 year olds, England
January – December 2013
CTAD TeamHIV & STI Department Centre for Infectious Disease Surveillance and Control
V 1.0 18/09/2014
Notes ❶ ❷ ❸
• Chlamydia activity data published by PHE are based on primary care and community service chlamydia data from Chlamydia Testing Activity Dataset (CTAD), and GUM clinic chlamydia data from GUMCAD.
• CTAD collects data on all NHS and local authority commissioned chlamydia tests carried out in laboratories in England.
• Data are presented by local authority of patient residence and aggregated up to PHE centre area and the England total.
• Data are attributed to local authorities using the patient’s postcode of residence. If this is not provided, other reported location data are used in this order: patient GP postcode; postcode of testing service; patient GP code; NCSP clinic code.
• Accurate attribution of tests by local authority is only possible if a valid postcode of residence is submitted to PHE. The proportion of records with a valid patient postcode has increased from 66% in 2012 to 74% in 2013.

Notes ❶ ❷ ❸
• CTAD data from GUM clinics reported by laboratories has been removed and replaced with GUM clinic data sourced from GUMCAD. This is because, unlike CTAD sourced GUM data, GUMCAD data contains information on patient area of residence.
• This data substitution relies on accurate coding of testing service type by laboratories reporting CTAD data. Inaccurate coding may lead to over or under counting of tests.
• Data includes chlamydia tests carried out on people aged 15 to 24 years inclusive.
• Data are cleaned and de-duplicated so one test per patient within a 42 day window is counted.
• Data includes tests where sex is male, female, and unknown/unspecified.
• Data includes all screening tests, diagnostic tests and tests on contacts.

Notes ❶ ❷ ❸
• Data includes chlamydia tests and diagnoses among people accessing services located in England who are also resident in England.
• The England total excludes tests which did not have sufficient location information to be attributed to a local authority of residence.
• Data represents the number of tests and diagnoses reported, and not the number of people tested or diagnosed.
• Data presented are based on tests with confirmed positive and negative results only. Tests with equivocal, inhibitory and insufficient results have been excluded as most people with these results are retested.
• Rates are calculated using ONS population estimates based upon the 2011 census. Rates for 2013 have been calculated using 2012 population estimates.
