Cluster-randomised feasibility trial of a chlamydia test and treat (TnT) service in further education colleges

Aquarius were involved in a recent cluster-randomised feasibility trial looking at whether provision of a same day test and treatment (TnT) service for chlamydia in further education colleges could be used to improve uptake of chlamydia testing in sexually active 16-24 year olds. The trial found that despite a high prevalence of chlamydia among sexually active students at the colleges, uptake of the free confidential TnT service was low. At the three colleges, 13% of students were tested when the service was first offered and 10% when it was offered again three months later. Interviews with students revealed that low uptake was associated with not feeling at risk of a sexually transmitted infection, perceptions of stigma, and lack of knowledge about sexually transmitted infections, while all students interviewed were positive about the TnT service itself.

Test n Treat – rapid STI testing and treatment in colleges: study protocol

Sexually active young people attending London further education (FE) colleges have high rates of chlamydia, but screening rates are low. We describe the study protocol for “Test and Treat” (TnT), an NIHR-funded research study. This is a cluster randomised feasibility trial of frequent, rapid, on-site chlamydia testing using the Cepheid GeneXpert system and same-day treatment in six FE colleges. As part of the study we also conducted qualitative and economic assessments to assess the feasibility of conducting a future large-scale trial to investigate if TnT reduces chlamydia rates. The methods for recruitment, participant data collection, sample collection and testing are described, for baseline and follow-up in the control and intervention groups. The statistical analysis plan for TnT has been published separately.

Exploring HCV eradication through diagnosis and treatment strategies

The World Health Organization aims to eradicate hepatitis C virus (HCV) by 2030. To achieve this, improved HCV diagnosis and treatment coverage are required. We explored the relationship between diagnosis and treatment in the next 5 years in Italy, France, and the UK to understand how to achieve the most benefit.

Rapid testing and treatment for sexually transmitted infections improve patient care and yield public health benefits

With collaborators at Chelsea and Westminster NHS Foundation Trust, we estimated the impact of a rapid testing and result notification service for patients testing for sexually transmitted infections at the Dean Street Express clinic. We found that a rapid testing service for asymptomatic infections resulted in 8 days’ faster time to result notification for CT and/or NG which enables faster treatment, thus reducing infectious periods and leading to fewer transmissions, unnecessary partner attendances and clinic costs, compared with those attending an existing ‘standard’ sexual health clinic.

Point-of-care tests for infectious diseases: Barriers to implementation across three London teaching hospitals

Our paper explores results of the acceptability and implementation issues of point of care tests (POCTs) in paediatric patients in three south London hospitals. Overall, we found that having a test result was thought to improve bed management and cohorting sick patients appropriately, reassure parents about their child’s condition, reduce hospital transmission, and rationalise further tests and treatment. Concerns focused on confidence about the test’s performance – particularly around false negatives not receiving proper management, how to manage discrepant results (i.e. the laboratory assay gave a different answer to the POCT), and training enough staff to run the test at the point of care.

Modelling the burden of non-muscle-invasive bladder cancer in Europe

Bladder cancer is relatively common in the EU. Most cases are non-muscle-invasive bladder cancer (NMIBC), classified into risk groups based on their chance of progression, which determines the frequency and duration of monitoring after treatment. We created a flexible tool to estimate the burden of NMIBC cases in eleven European countries and estimated the number of monitoring cystoscopies by risk group based on national and regional guidelines.

Mapping the diagnostic pathway for breast cancer in England and comparison to Europe

Breast cancer is the most common cancer in women in England and the second most common cause of cancer death. We mapped the breast cancer diagnostic pathway in England and rest of Europe and estimated the number of women transitioning through each step of the pathway, and the number of symptomatic women. We propose a new metric to discuss breast cancer screening, annual effective screening rate, to allow for comparison of the effectiveness of different breast cancer interventions across Europe.

Providing integrated HIV treatment and care for stable patients in general practice

We implemented a nurse-delivered integrated HIV and primary care service pilot study for stable patients in two local inner city general practices. Initial results from the patients in the study indicate that a novel model of HIV care with a greater emphasis on patient convenience appears to have high levels of patient satisfaction and favourable treatment outcomes; further work will analyse the costs and impact of the service.

The cost and tariff reimbursement of idiopathic pulmonary fibrosis in England

We explored patient pathways for the diagnosis, management and monitoring of idiopathic pulmonary fibrosis (IPF). This was based on NICE published pathways, and interviews with healthcare staff from 14 hospital trusts across England. Data were used in our in-house tool to estimate the cost of each pathway, which were compared to the tariff reimbursement. We found large variation across England in how services for IPF patients are delivered, and variation compared to the NICE pathway.

Treatment for stable HIV patients in England: can we save costs and improve patient care?

We estimated the costs of changing the frequency of clinic appointments and drug dispensing arrangements for stable HIV patients in England. Results indicated that 6-monthly appointments and 3-monthly home delivery of drugs is the least expensive option and could result in £2000 savings per patient. This translates to annual cost reduction of about £8 million for the estimated 4000 eligible patients not currently on home delivery in England.
