Exploring the value of a rapid, on-demand test for the detection of human papillomavirus

We explored the use of a rapid, on-demand human papillomavirus (HPV) test as part of a cervical screening programme. Through semi-structured interviews with experts from across the UK, we found that a co-located, laboratory-based, and on-demand HPV test following cytology could reduce the time to results by up to a week, whilst a near-patient test under primary HPV screening followed by cytology triage could radically change the testing paradigm, with most women notified the same day.

Estimating the true costs of splitting HIV antiretroviral drugs

Problem: A regional UK commissioning decision in 2010 mandated that when the component drugs of Combivir—a combination therapy for HIV—come off patent, doctors must prescribe the individual drugs instead. This was driven by a perception that the generic component drugs are cheaper in the immediate-term and so more efficient overall. As our pharmaceutical client’s HIV combination drug was soon to come off patent, they wanted to help commissioners understand the full healthcare costs of such a policy, to inform future decisions.

Approach: We worked with our client and clinicians in Nottingham University Hospital’s HIV clinic who had patient-level care data before and after the commissioning change. We planned the analysis and identified which costs would be used and which data were required.

Impact: Our work contributes to the evidence-base of the costs of prescribing patients a single dose therapy over multiple doses. It has changed people’s perceptions of the costs of treating long-term conditions with combination drugs, and helped commissioners to make policy decisions about mandating use of particular drugs whilst taking a holistic view of healthcare.

Understanding Idiopathic Pulmonary Fibrosis patient care delivery and costs

Problem: Idiopathic Pulmonary Fibrosis (IPF) is a chronic condition, often with poor prognosis. Although there are NICE guidelines for managing IPF patients, care has varied across England; it has depended on how a clinic’s services are set up and what local resources are available. Our clients wanted to support local specialist centres as they document how their clinics managed IPF patients, how local pathways varied from the NICE benchmark care, and estimate affordability of providing care to patients.

Approach: We generated a gold-standard benchmark pathway for IPF patients based on the NICE guidelines and published literature using our pathway mapping tool, Dots. With our client we designed and conducted structured interviews with clinicians and service managers to explore how their IPF patients are managed and map out local pathways and resource use. Finally, we estimated the costs of care and compared it to our benchmark national pathway using the Dots.

Impact: All of the clinics were given their results so they could understand how their IPF pathways compared to the benchmark and to other clinics, both clinically and in cost-wise. It is anticipated that results could inform the development of a national tariff, as the estimated costs of providing care was over 40% more than currently reimbursed.

The benefits and cost-savings of a new point-of-care test for chlamydia and gonorrhoea

Problem: Cepheid’s Xpert® CT/NG test is a high performance point-of-care test for chlamydia and gonorrhoea, and offers a promising advance in the diagnosis and control of two common sexually transmitted infections. When the test was launched in 2013, Cepheid wanted to understand how sexual health clinics in England might use it and to develop evidence comparing its costs and benefits to standard laboratory tests.

Approach: We approached the challenge in two projects. For the first, we defined the current patient pathways for chlamydia and gonorrhoea testing treatment and compared them to what they would be if a rapid POCT was used. We held workshops with staff in four sexual health clinics, asking them to map out the current patient pathways for chlamydia and gonorrhoea diagnosis and treatment. We then helped them brainstorm ways in which their services might include a point-of-care chlamydia and gonorrhoea test, and describe how this would change their patient pathways. Finally, we used Dots, our cloud-based pathway builder tool, build to estimate the costs of the pathways. The work indicated that the pathways could be streamlined with a point-of-care test, and we estimated that this would cost less to deliver than current practice.

For the second project, we developed an economic model to compare the overall costs and benefits of a point-of-care test to standard care. We combined the results of our first project with previous work our team had conducted on chlamydia and gonorrhoea testing and management. The model showed that the test could deliver £10million in cost savings, and give far more effective management of chlamydia and gonorrhoea at a population level. Our results were published in Sexually Transmitted Infections, and have been presented at national and international conferences.

Impact: Our work gave Cepheid the empirical evidence to demonstrate the value and potential impact of adopting their test in clinics. Since our projects, Cepheid has had increasing interest in the test, and several centres have purchased it. This includes a major London sexual health clinic which has introduced a new testing service as a result.

The financial and service implications of splitting fixed-dose antiretroviral drugs – a case study

Switching to cheaper generic antiretroviral drugs for HIV patients may appear cost saving over fixed-dose combinations, and be an appealing way to reduce healthcare costs. However, the additional clinical costs may outweigh the initial cost savings of the drugs, and switching may cause confusion for some patients, risking loss of adherence. Our analysis provides evidence that can help commissioners make better policy decisions about drug provision.

Mapping patient pathways and cost of point of care versus standard testing and treatment for chlamydia and gonorrhoea in sexual health clinics

This study aimed to explore the current patient pathways for the diagnosis and treatment of chlamydia and gonorrhoea in England. We conducted workshops in four sexual health clinics, and asked them detail the steps and resources used in screening, diagnosis and treatment, and what would change if they had a point of care test (POCT) for chlamydia and gonorrhoea diagnosis. Using a POCT could lead to reduced clinical time and costs, and may lead to more appropriate and quicker care for patients.

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.

The cost-effectiveness of point of care tests for chlamydia and gonorrhoeae in sexual health clinics

Replacing standard laboratory tests for chlamydia and gonorrhoea with a rapid point of care test could be cost-effective if implemented in genitourinary medicine clinics in England. It could save the National Health Service an estimated £10 million annually, and patients would benefit from fewer unnecessary treatments and reduced complications from infection, and it could prevent the number of transmissions.
