GUMCAD STI Surveillance System
Guidance on the collection and reporting of data for GUMCAD, the surveillance system for sexually transmitted infections (STIs) in England.
About
The GUMCAD STI Surveillance System is the new name for the Genitourinary Medicine Clinic Activity Dataset (GUMCAD).
GUMCAD is the mandatory surveillance system for STIs and collects data on STI tests, diagnoses and services from all commissioned sexual health services in England. It is an electronic, pseudonymised patient-level dataset reported by about 400 services.
UK Health Security Agency (UKHSA) co-ordinates and manages the quarterly data collection, processing, storage, analysis, and reporting of GUMCAD data on behalf of the Department of Health and Social Care (DHSC).
Data is:
- reported quarterly to service providers and local authority sexual health commissioners
- published annually as official statistics
- used for the chlamydia detection rate on DHSC’s Public Health Outcomes Framework
All commissioned specialist (level 3) and non-specialist (level 2) sexual health services are required to complete and return GUMCAD data to UKHSA.
Further details on the development of GUMCAD are available in this article in Eurosurveillance. Details on the levels of sexual health service provision are available in the Standards for the management of STIs provided by the British Association for Sexual Health and HIV.
