Plain English Summary
Background and study aims
Increasing numbers of patients are diagnosed with sexually transmitted infections (STIs) in their GP surgery. This study is concerned with finding out the best way to enable treatment for the sexual partners of individuals diagnosed with STIs in their GP practice. This is called "partner notification". Treatment of partners is important for two reasons - to protect the original patient from reinfection, and to prevent the further spread of infection by infected partner(s). We will compare three different approaches to partner treatment: patient referral, contract referral and provider referral. Patient referral is where patients are simply given information and asked to tell their partner about the problem and the need to be treated. Contract referral is where, in addition to patient referral, patients will be asked to agree to a specialist health adviser (contact tracing expert) to inform their partner(s) if this has not been done after a period of time (say, a week). Provider referral is where, in addition to patient referral, patients will be offered the option of a specialist health adviser contacting their partner(s) at the time of diagnosis.
Who can participate?
Patients over the age of 16 diagnosed with sexually transmitted infections at participating GP practices
What does the study involve?
Participating GP practices are randomly allocated into three groups, and trained to manage all their patients according to one of the above approaches. We measure how well these three approaches to partner notification work by comparing how many partners get treated. We also measure how many of the original patients are still infected in each group, as this is also a good measure of partner notification. We also compare the cost effectiveness of the three approaches.

| Scientific title | The relative clinical and cost-effectiveness of three contrasting approaches to partner notification for curable sexually transmitted infections (STIs): a cluster randomised trial in primary care |
| Study hypothesis | Increasing numbers of patients are diagnosed with sexually transmitted infections (STIs) in their GP surgery. We want to find out the best way to arrange treatment for the sexual partners of individuals who are diagnosed with STIs in their GP practice (partner notification). Treatment of partners is important for two reasons; to protect the original patient from re-infection, and to prevent the further spread of infection. We will compare three different approaches: 1. Patient referral 2. Contract referral 3. Provider referral GP practices will be randomly split into three groups, and will manage all their patients according to ONE approach. We will measure how well these three approaches work, by comparing how many partners get treated and how many of the original patients are still infected in each group. In addition, we will do an economic study of the cost-effectiveness of each approach, and compare them. We are testing the following null hypothesis: Provider referral and contract referral offer no advantage over patient referral in partner notification for curable sexually transmitted infections in the primary care setting.

| Intervention | We will compare three different interventions in partner treatment: 1. Patient referral: patients are given information about their infection, and asked to tell their partner about the problem and the need to be treated 2. Contract referral: in addition to point 1 above, patients will be asked to agree to a specialist health adviser (contact tracing expert) to inform partner(s) if this has not been done after an agreed period of time (usually two days) 3. Provider referral: in addition to point 1 above, patients will be asked to agree to a specialist health adviser contacting one or more of their partner(s) at the time of diagnosis Treatment is a communication process without a defined duration. Follow up will be 10 - 12 weeks. |
| Intervention type | Other |
| Primary outcome measure | 1. Number of main partners per index patient treated for chlamydia and/or gonorrhoea/nonspecific urethritis/pelvic inflammatory disease 2. Proportion of index patients testing negative for the relevant STI at 3 months |
| Secondary outcome measures | 1. Number of partners per index patient presenting for treatment 2. Proportion of index patients having at least one partner treated 3. Number of main, casual and ex-partners per index patient tested for the relevant STI 4. Number of main, casual and ex-partners testing positive for the relevant STI 5. Number of index patients tested for HIV by 3 months 6. Number of current partners tested for HIV by 3 months 7. Time to definitive treatment of index patient for the relevant STI 8. Time to definitive treatment of current partner for the relevant STI 9. Uptake by index patients of "contract" and "provider" referral for one or more partners, within the relevant randomised groups 10. Patient-related factors impacting on partner notification or STI disclosure to main, casual and ex-partners An important secondary aim is to identify what patient-related or psychological factors impact on disclosure. |
