Data sources:

(i) GP diagnoses of chlamydia and gonorrhoea are estimated from services included in the Clinical Practice Research Datalink.

(ii) Non-GUM diagnoses of chlamydia are from surveillance returns from NCSP services from 2003 to 2011.

(iii) GUM diagnoses of chlamydia and gonorrhoea are from GUM clinic KC60 returns (2005–2008) and GUM clinic GUMCAD returns (2009–2011).

*Per 100 000 population.

†The NCSP was implemented in 2003.

‡Untreated patients diagnosed in GP with chlamydia or gonorrhoea are assumed to be referred to GUM clinics, thus, to prevent double counting, the total number of diagnoses excludes these.

GP, general practices; GUM, genitourinary medicine clinics (otherwise known as ‘sexually transmitted infection clinics’); GUMCAD, GUM clinic activity dataset; KC60, Korner Code-60; NCSP, National Chlamydia Screening Programme.
