This is the homepage of the MSTIC study, which is based at UCL's Centre for Sexual Health and HIV Research, and funded by the Medical Research Council.  The full title of the study is Public health outcomes, costs and cost-effectiveness of GUM and primary care based STI services: How to maximise STI control for a population.

Lay summary

Patients with sexually transmitted infections (STIs) attend a variety of different services, including specialist genitourinary medicine (GUM) clinics, and GPs. The availability of services for STIs depends on many factors including whether the area is rural or urban. In 2001, the government published the ‘National Strategy for Sexual Health and HIV’. This proposed that, in future, more services for STIs should be provided in primary care (GP surgeries).

Since then, many areas have started to develop STI services provided by GPs and nurses in primary care. These services, usually called ‘Locally Enhanced Services’ (LES) vary considerably from place to place, and the public health specialists who plan services have found them difficult to plan. The aim of services for STIs, whether in primary care or GUM clinics, is to reduce the transmission of STIs as cost-effectively as possible. A number of factors will influence how well this is achieved by the local services –the capacity of the services, to what extent they are treating the partners of people diagnosed with STIs, whether they are seeing high risk populations (with high rates of STIs), or lower risk people. These can be hard to measure.

We are building a decision aid that will help public health specialists and sexual health service decision-makers plan the most cost-effective services for different kinds of population (e.g. rural vs. urban, younger vs. older, populations with different ethnic mixes). Our team of public health specialists, clinicians, statisticians, and health economists will build a ‘Decision Analytic Model’. This is a mathematical tool that will help decision makers identify the key elements of service provision (in primary care or GUM), that could impact on the effectiveness (e.g. the number of cases of gonorrhoea or chlamydia prevented), and the cost effectiveness (e.g. incremental cost per case of gonorrhoea or chlamydia prevented) of the differing combinations of primary care and GUM provision being considered. We will develop and use a Rapid Assessment Module that will collect the data needed to describe the elements of GUM and primary care STI services needed for the Decision Analytic Model. The ‘end product’ of the research will be a web-based tool that can be used by decision-makers (and, indeed the public), to support the evidence-based planning of services for STIs.
