Introduction
I've worked on economic evaluations across a variety of clinical areas including diabetic retinopathy, stroke rehabilitation, depression, personality disorder and orthotics; amongst others. Along the way I've employed methods alongside clinical trials and using decision models, as well as some more inventive approaches. My interest is most strongly drawn towards research in to the methods and theory around valuing health, and the evaluative space of economic evaluation.

There is growing interest in cost-effectiveness thresholds as a tool to inform resource allocation decisions in health care. Studies from several countries have sought to estimate health system opportunity costs, which supply-side cost-effectiveness thresholds are intended to represent. In this paper, we consider the role of empirical estimates of...

Introduction: Babies born before 30 weeks’ gestation are at increased risk of major clinical complications and have greater nutritional requirements. Where nutritional requirements cannot be sufficiently provided for by the mother’s own milk (MOM), routine care in England uses cow milk-derived fortifiers and formulas. However, the use of cow milk i...

By convention, values for generic ‘preference-based’ measures, such as the EQ-5D, are anchored at 1 = full health and 0 = dead. This paper challenges the assumption that anchoring health state values at ‘dead = 0’ is a necessary condition for values to be used in quality-adjusted life year (QALY) estimation. The authors consider five propositions,...
Thesis
Full-text available
Publicly provided health screening programmes tend to offer standardised screening for a fixed eligible population. Recently, the development of risk calculation engines has introduced the potential for the stratification of screening based on individuals' risks of disease onset. This possibility raises practical, methodological, and ethical challe...
Conference Paper
Background The use of 'bolt-on' descriptors has been proposed to improve the sensitivity and responsiveness of the EQ-5D in certain contexts. An Australia/UK collaboration is developing bolt-ons for vision (5L-Vis) and cognition (5L-Cog) for self-and proxy-completion, using qualitative and quantitative methods. The application of qualitative method...

OBJECTIVES Access to non-pharmacological interventions for insomnia is limited, despite evidence for their effectiveness. This is due in part to a shortage of trained providers. Digital cognitive behavioural therapy for insomnia (dCBT-I), which requires less input per session, is there-fore an attractive complement or substitute to face-to-face cog...

OBJECTIVES Evidence suggests that, in specific circumstances, the EQ-5D is insensitive to changes or differences in health status. One possible solution is to add 'bolt-on' dimensions to the core EQ-5D dimensions, to provide additional information about the impact of certain conditions or symptoms on health. In this study, we developed EQ-5D-5L bol...
Article
Transparency in decision modelling is an evolving concept. Recently, discussion has moved from reporting standards to open-source implementation of decision analytic models. However, in the debate about the supposed advantages and disadvantages of greater transparency, there is a lack of definition. The purpose of this article is not to present a c...

Introduction Currently, all people with diabetes (PWD) aged 12 years and over in the UK are invited for screening for diabetic retinopathy (DR) annually. Resources are not increasing despite a 5% increase in the numbers of PWD nationwide each year. We describe the rationale, design and methodology for a randomised controlled trial (RCT) evaluating...
Conference Paper
Background: By convention, values for the EQ-5D are anchored at 1 = full health and 0 = dead for use in estimating QALYs for cost effectiveness analysis. Consequently, the stated preference methods used to value health states often involve consideration of the state 'dead' or 'immediate death'. Using dead as an anchor also implies that states worse...
Presentation
Eligibility for national screening programmes can be personalised according to individual risk in order to improve outcomes and reduce costs. Existing methods of economic evaluation can be adapted to identify risk thresholds and help optimise services. We describe the development of a decision model used to evaluate the cost-effectiveness of risk-b...
Article
Introduction There is growing evidence that many people attending annual screening for diabetic retinopathy in the United Kingdom (UK) are at low risk of developing the disease. This has led to new policy statements. However, the basis on which to establish a risk-based individualized variable-recall screening program has not yet been determined. W...

Economic evaluation in human health care tends to adopt an ’extra-welfarist’ approach. The key manifestation of extra-welfarism is the maximisation of health within a given budget. We outline the extra-welfarist framework and evaluate its applicability to various contexts of animal welfare. Many of the reasons for the adoption of an alternative to...

Losing a loved dog accidentally or through theft is traumatic. Roads are busier and pet theft increasing in the UK. Owners feel loss akin to human bereavement. Searching for a pet is costly in financial and emotional terms. This work uses the exemplar of Harvey’s Law to illustrate the cost. In 2014 the Highways Agency withdrew routine scanning and...

Evidence regarding the effectiveness of health technologies can be distorted via numerous mechanisms, including publication bias, methodological errors, over- interpretation of findings and fraud. In recent years, popular science writers have brought these issues to the fore, resulting in popular movements to improve the credibility of science. One...
Conference Paper
Background. Systematic reviews of health state utility values (HSUVs) are recommended for the identification of parameters in decision modelling. However, most models adopt a single source and are susceptible to biased estimates. Diabetic retinopathy is a leading cause of blindness and earlier stages of disease may affect quality of life. A synthes...
Conference Paper
Background Diabetic retinopathy is a leading cause of blindness in the working age population in Europe. Effective treatment is available that can slow disease progression and prevent vision loss and its associated costs. However, it is important to detect retinopathy in the early stages of disease before patients experience symptoms. Therefore, al...

Background Persistent moderate or severe unipolar depression is common and expensive to treat. Clinical guidelines recommend combined pharmacotherapy and psychotherapy. Such treatments can take up to 1 year to show an effect, but no trials of suitable duration have been done. We investigated the efficacy and cost-effectiveness of outpatient-based,...
Article
In this commentary, we consider the recent recommendation by the UK National Screening Committee (NSC) that people with diabetes at low risk of sight loss should be invited to screening every 2 years rather than annually [1]. We broadly support this recommendation but believe that there are important outstanding questions that require attention bef...

Chapter
End-of-life care has a number of characteristics that make economic evaluation particularly challenging. These include proximity to death, the improbability of survival gain, individuals’ changing priorities, declining cognition and effects on close persons. In view of these particularities of end-of-life care, some researchers have determined that...

Personalised medicine presents the opportunity to improve outcomes by accounting for patient heterogeneity and providing individualised care. However, this raises practical and ethical dilemmas and is a challenge for health economists. We argue that there is one form of personalised medicine risk-­based screening ­ that can be practically and ethic...

Most frequent attendance in primary care is temporary, but persistent frequent attendance is expensive and may be suitable for psychological intervention. To plan appropriate intervention and service delivery, there is a need for research involving standardized psychiatric interviews with assessment of physical health and health status. Objective....
Conference Paper
Background: Combined psycho- and pharmacotherapy has been found to offer greater effectiveness than single interventions, though evidence from randomised controlled trials remains limited. Individuals with resistant depression have limited treatment options in the UK. Aim of the Study: This study sought to determine the cost-effectiveness of a spec...

Personalised medicine can raise practical and ethical dilemmas. We argue that there is one form of personalised medicine — risk-based screening — that can be practically and ethically implemented. There is necessarily a relationship between an individual’s risk of disease onset and the cost-effectiveness of screening them for that disease. The expe...

Background People with diabetic retinopathy tend to have lower levels of health-related quality of life than individuals with no retinopathy. Strategies for screening and treatment have been shown to be cost-effective. In order to reduce the bias in cost-effectiveness estimates, systematic reviews of health state utility values (HSUVs) are crucial...

This is where the 'Drop Dead' project properly started for me, with a seminar to my colleagues. In it, I focus on the idea that the states we use for anchors in health state valuation aren't well-chosen. It took six years for these ideas to make their way into the wider world. Looking back, I knew very little about health state valuation in 2014, b...

Occupational therapy interventions, such as home visits, have been identified as being resource-intensive, but cost-effectiveness analyses are rarely, if ever, carried out. We sought to estimate the cost-effectiveness of occupational therapy home visits after stroke, as part of a feasibility study, and to demonstrate the value and methods of econom...
Article
Background: A quarter of UK strokes occur in working age people. Fewer than half resume work. Rehabilitation frequently fails to address work needs and evidence for post-stroke vocational rehabilitation is lacking. This pilot trial tested the feasibility of delivering SSVR and measuring its effects and costs compared to usual care (UC). Method: Pre...

A high proportion of individuals admitted to specialist secure hospital services for treatment of personality disorder do not complete treatment. Non-completion has been associated with poorer treatment outcomes and increased rates of recidivism and hospital readmission, when compared with individuals who do complete treatment or who do not receive...
Article
Resources are always scarce, but the possible uses of these resources are limitless. This simple observation underlies much of what economists do. It leads to competing demands from different parties and requires individuals and organisations to make choices about their use of scarce resources. The primary purpose of economics is to help us underst...
Article
Advancements in our understanding of the causes and correlates of disease mean that we are now able to estimate an individual's level of risk. This, and the ever-increasing need for healthcare interventions to be cost-effective, has led to calls for the introduction of risk-based screening. Risk-based screening would involve the use of information...
