2. Headlines
Reducing undiagnosed Chlamydia remains a key Public Health Outcome Framework indicator across the UK
The detection rate indicator (DRI) required to reduce the incidence of infection is 2,300 cases per 100,000 population annually.
In 2014 DRI in TH was 1877
19/33 Local Authorities in London
127/326 LA in England
Whilst improvement has been made, locally we remain some way from the DRI

5. How are we driving improvement?
Increasing accessibility to testing:
Self sampling available across range of settings including >40 Community Pharmacies
Increase in targeted campaigns promoting testing to year olds
Preventing spread and re-infection:
Focused efforts to improve partner treatment and testing
PN outcome rate in GUM, pharmacy & CASH = 1.05 achieved (vs. 0.6 BASHH/NCSP standard)
Improving retest rates among those diagnosed with infection at 3 months (currently 35%; includes GP)

6. What do we want from General Practice?
Follow EMIS prompt and offer annual screen to any year olds accessing practice
20-24 year olds & MSM in Tower Hamlets have higher rates of infection than national average
Continue to treat and initiate partner notification for any patients diagnosed
41% of people attending as contacts of infection locally tested positive for Chlamydia
Ensure all patients diagnosed with Chlamydia are offered a retest after 3 months
7% of patients test positive at this time
Inform patients of this when you treat them
