1. Is the chlamydia screening programme worthwhile? BRITISH SOCIETY FOR MICROBIAL TECHNOLOGY 27 th ANNUAL SCIENTIFIC MEETING 18 May 2012 Dr Angie Bone, Director NCSP angie.bone@hpa.org.uk http://www.chlamydiascreening.nhs.uk

2. Outline Update on the National Chlamydia Screening Programme Is chlamydia still an important public health problem? How do we know if screening is working? Is it cost-effective? What are young people’s views? How is progress being monitored? What do local areas need to do? Olympics and Sexual Health

3. Chlamydia trachomatis Commonest bacterial STI in England Majority of infections are asymptomatic Highest rates of infection among young people Easy to detect using NAAT tests Easy to treat with antibiotics Untreated infections can cause PID, ectopic pregnancy, infertility Chlamydia infected culture (Wellcome Images)

4. The National Chlamydia Screening Programme (NCSP) in England Aims to control chlamydia thus reducing transmission and sequelae Opportunistic screening of sexually active < 25 year olds - Annually - Change of sexual partner Clinical and non-clinical venues Standards for treatment and partner notification

5. The NCSP 2003 to 2010: What went well High volumes screened Expansion of sexual health services into community with range of providers Early adoption of new technologies Quality assurance programme Involvement of men Reaching those at higher risk and the socio- economically deprived 5

6. The NCSP 2003 to 2010: Areas for improvement Value for money, cost variations Lack of integration with other sexual health services Engagement of some providers e.g. GP’s Scientific/policy controversies 6

7. So, is it worthwhile to continue…? Chlamydia remains a cause of serious reproductive morbidity, with costs to the service and individuals Evidence of impact on prevalence - Modelling - changes in percentage infected amongst those tested - Seroepidemiology

10. Predicted chlamydia prevalence, 16 to 24 year olds (2000/01 to 2012/13) From Dorey et al 2012, accepted for publication in STI 10

11. So, is it worthwhile to continue…? Chlamydia remains a cause of serious reproductive morbidity, with costs to the service and individuals Evidence of impact on prevalence - Modelling - changes in percentage infected amongst those tested - seroepidemiology Evidence of impact on sequelae - RCT evidence - Changes in PID rates

12. Rate of PID diagnoses* in General Practice by age group (females 16 to 44 years old) *Definite/probable PID diagnoses Source: French et al. STD 2011.

13. So, is it worthwhile to continue…? Remains a cause of reproductive morbidity, with substantial costs Evidence of impact on prevalence - Modelling - changes in percentage infected amongst those tested - seroepidemiology Evidence of impact on sequelae - RCT evidence - Changes in PID rates Wider benefits - Awareness of chlamydia - Expanding sexual health services into community - Involving men - Reducing stigma

14. Is it cost-effective? Three studies indicate screening may be cost-effective Depends on parameters used in model both for costs and benefits Several elements to screening pathway and huge variety of delivery methods Average cost per screen £27; per diagnosis £437* Recent policy initiatives to reduce costs and improve sustainability Emphasis on partner notification Adams E and Turner K: Invest to Save in the South West 2012

15. What are young people’s views? Don’t always see chlamydia as relevant to them Prefer a blanket approach to testing Want to be asked rather than have to ask for a test Don’t want to have to give a sexual history Need to be sure of confidentiality Want options for testing – hcp/remote testing Want results quickly Want support to be available to manage positive results

16. So, is it worthwhile to continue…? YES!

17. Where we are now DH “Future direction” statement July 2011 Drives to reduce outreach and integrate ct screening Chlamydia Testing Activity Dataset (CTAD) Move from coverage to diagnosis rate PH outcomes framework - A level of at least 2400 chlamydia diagnoses per 100,000 residents aged 15-24 - At present, aim is to achieve HIGH levels of diagnoses - Recommended level only achievable through widespread testing

19. What do local areas need to do? 1.Safeguard chlamydia screening and other sexual health services during transition 2.Know your data – available on the HPA/NCSP websites 3.Embed chlamydia screening in primary care and sexual health services – general practice is key 4.Enable remote testing 5.Focus outreach on hard to reach groups 6.Emphasise screening annually and on change of partner; partner notification very important 7.Listen to young people

20. The Olympics and Sexual Health – what might we expect? Mass gathering – increased risk of infectious diseases In terms of STI, possibility of increased transmission: - increase in casual workers - increase in sex workers - increase in sexual risk taking Increased demand on sexual health services Sydney 2000 (McNulty et al 2003) - Two fold increase in diagnoses of bacterial STI’s - Increase in new patient visits to sexual health services (symptomatic or STI contacts)

21. The Olympics and Sexual Health - preparation and response Promotion of contraception, condom use & NHS Choices LOCOG – Durex sexual health campaign Effective sign-posting, rapid referral and extended opening hours to sexual health services Onsite sexual health services to construction workers Temporary outreach centre in Stratford GUM clinicians and labs to be alert to any new or rapidly increasing infections – report to local HPU Olympic codes in GUMCAD - surveillance
