INTRODUCTION Patients dying a short time after receiving palliative radiation are unlikely to have received benefit and may experience harm. To monitor the potential for avoidable harm, 30-day mortality following palliative radiation has been recommended for use as a quality indicator and the Royal College of Radiologist have recommended a rate of lower than 20%. At the Canterbury Regional Cancer and Haematology Service in Christchurch, New Zealand (CRCHS), we investigated 30-day mortality and evaluated the prognostic value of the TEACHH model in our population. METHODS Palliative treatments from two, two-year periods (2012/2013 and 2016/2017) were retrospectively reviewed. We analysed 30-day mortality and several influencing variables. Patients were divided into three groups using the TEACHH model (type of cancer, performance status, age, prior palliative chemotherapy, prior hospitalizations and hepatic metastases). RESULTS There were 1744 patients; 30-day mortality was 10% and was higher in patients with lung cancer (17% vs. 8% in non-lung cancer patients, P

Background Autosomal dominant polycystic kidney disease (ADPKD) is the leading inheritable cause of end-stage renal disease (ESRD); however, the natural course of disease progression is heterogeneous between patients. This study aimed to develop a natural history model of ADPKD that predicted progression rates and long-term outcomes in patients with differing baseline characteristics. Methods The ADPKD Outcomes Model (ADPKD-OM) was developed using available patient-level data from the placebo arm of the Tolvaptan Efficacy and Safety in Management of ADPKD and its Outcomes Study (TEMPO 3:4; ClinicalTrials.gov identifier NCT00428948). Multivariable regression equations estimating annual rates of ADPKD progression, in terms of total kidney volume (TKV) and estimated glomerular filtration rate, formed the basis of the lifetime patient-level simulation model. Outputs of the ADPKD-OM were compared against external data sources to validate model accuracy and generalisability to other ADPKD patient populations, then used to predict long-term outcomes in a cohort matched to the overall TEMPO 3:4 study population. Results A cohort with baseline patient characteristics consistent with TEMPO 3:4 was predicted to reach ESRD at a mean age of 52 years. Most patients (85%) were predicted to reach ESRD by the age of 65 years, with many progressing to ESRD earlier in life (18, 36 and 56% by the age of 45, 50 and 55 years, respectively). Consistent with previous research and clinical opinion, analyses supported the selection of baseline TKV as a prognostic factor for ADPKD progression, and demonstrated its value as a strong predictor of future ESRD risk. Validation exercises and illustrative analyses confirmed the ability of the ADPKD-OM to accurately predict disease progression towards ESRD across a range of clinically-relevant patient profiles. Conclusions The ADPKD-OM represents a robust tool to predict natural disease progression and long-term outcomes in ADPKD patients, based on readily available and/or measurable clinical characteristics. In conjunction with clinical judgement, it has the potential to support decision-making in research and clinical practice.

BACKGROUND AND AIMS The hepatitis C virus (HCV) remains a considerable public health challenge. Novel direct-acting antiviral (DAA) regimens offer high cure rates and the promise of reduced HCV incidence and prevalence following the up-scaling of treatment. This has focused attention towards affordability. This study aimed to estimate the economic value of cure to evaluate the treatment costs justifiable from the patient perspective. PATIENTS AND METHODS A published, validated HCV model was utilized to contrast clinical and cost outcomes for patients aged 30-70 years, stratified by METAVIR F0-F4, for (i) no treatment and (ii) successful treatment [i.e. sustained virologic response (SVR)] ignoring the cost of treatment. Regression equations were fitted and used to determine the financial expenditure justifiable to achieve a cost-neutral or a cost-effective [£20 000 per quality-adjusted life-year (QALY)] cure. Model inputs were derived from UK literature; costs and utilities were discounted at 3.5% over a lifetime horizon. RESULTS To achieve cost-neutrality, the maximum discounted expenditure justifiable for SVR was £3774-43 607 across ages and fibrosis stages. Spending between £19 745 (70 years, F0) and £188 420 (30 years, F4) on SVR is expected to be cost-effective at £20 000/QALY willingness-to-pay threshold. CONCLUSION Heterogeneity across HCV patients is considerable, which can obscure the relevance of conventional cohort-based economic models evaluated at the mean, particularly when considering the value of treatment at the individual patient level. By quantifying the full exposition of HCV cost-savings and health benefits realizable following HCV cure, this study provides insight into the economic value of successful treatment from the patient perspective.

Insulin-treatment in type 1 diabetes mellitus (T1DM) is associated with elevated risk of hypoglycaemia and weight gain, which may act as a barrier to achieving optimal glycaemic control. For patients inadequately controlled by insulin alone, adjunct dapagliflozin can reduce body weight and improve glycaemic control without increased risk of hypoglycaemia. This study aimed to empirically quantify the inter-relationships between hypoglycaemia, body mass index (BMI) and quality of life using DEPICT-2 trial data. A two-stage linear regression framework evaluated (1) the relationship between hypoglycaemic fear score (HFS) and the occurrence of severe hypoglycaemia, the number of documented symptomatic events and patient age, and (2) the relationship between health-related utility (EQ-5D) and prognostic factors for utility, including HFS and BMI. Model selection was based on clinically-relevant factors. A linked evidence approach correlated the relationship between treatment, hypoglycaemia incidence and HbA1c over 52-weeks, to the relationships captured within the regression models. HFS increased as a function of incidence of severe hypoglycaemia (coefficient estimate (CE): 14.62, p=0.004) and frequency of symptomatic events (log transposed, CE: 1.32, p=0.0026). In turn, increased HFS and increased BMI were both independently associated with a significant reduction in utility (CE 0.0024, p Disclosure J.

Objectives. Type 2 diabetes mellitus (T2DM) clinical guidelines focus on optimizing glucose control, with therapy escalation classically initiated within a “failure-based” regimen. Within many diabetes models, HbA1c therapy escalation thresholds play a pivotal role, controlling duration of therapy and, consequently, incremental costs and benefits. The objective of this study was to assess the relationship between therapy escalation threshold and time to therapy escalation on predicted cost-effectiveness of T2DM treatments. Methods. This study used the Cardiff Diabetes Model to illustrate the relationship between costs and health outcomes associated with first-, second-, and third-line therapy as a function of time on each. Data from routine clinical practice were used to contrast predicted costs and health outcomes associated with guideline therapy escalation thresholds compared with clinical practice. The impact of baseline HbA1c and therapy escalation thresholds on cost-effectiveness was investigated, comparing a sodium/glucose cotransporter 2 inhibitor v. sulfonylurea added to metformin monotherapy. Results. Lower thresholds are associated with a shorter time spent on monotherapy, ranging from 1.1 years (escalation at 6.5%) to 13 years (escalation at 9.0%) and an increase in total lifetime cost of therapy. Treatment-related disutility is minimized with higher thresholds because progression to insulin is delayed. Using metformin combined with either dapagliflozin or a sulfonylurea to illustrate lower baseline HbA1c and/or higher therapy escalation thresholds was associated with increased cost-effectiveness ratios, driven by a longer duration of therapy. Discussion. A marked difference in treatment cost-effectiveness was demonstrated when comparing routine clinical practice with guideline-advocated therapy escalation. This is important to both health care professionals and the wider health economic community with respect to understanding the true cost-effectiveness profile of any particular T2DM therapy option.

Since 1997 Kick It Out has worked as a charitable organization that promotes equality and inclusion, as well as challenging all forms of discrimination in English football. Prior to this, and since its formation in 1993, the organization had worked under the name of Let’s Kick Racism Out of Football as a campaign against racism within the game. Since 2012, the remit of the organization has broadened and it works both proactively and reactively within football and the communities around it. Kick It Out is widely recognized in football and society due to its campaigning activities that raise awareness of the ongoing issues relating to equality, diversity and discrimination in football. However, there still often exists a lack of awareness of the organization’s day-to-day work in challenging discrimination, breaking down barriers and making the sport more inclusive.

The aim of this paper is to estimate the relative cost-effectiveness of treatment regimens for managing patients with sciatica. A deterministic model structure was constructed based on information from the findings from a systematic review of clinical effectiveness and cost-effectiveness, published sources of unit costs, and expert opinion. The assumption was that patients presenting with sciatica would be managed through one of 3 pathways (primary care, stepped approach, immediate referral to surgery). Results were expressed as incremental cost per patient with symptoms successfully resolved. Analysis also included incremental cost per utility gained over a 12-month period. One-way sensitivity analyses were used to address uncertainty. The model demonstrated that none of the strategies resulted in 100% success. For initial treatments, the most successful regime in the first pathway was nonopioids, with a probability of success of 0.613. In the second pathway, the most successful strategy was nonopioids, followed by biological agents, followed by epidural/nerve block and disk surgery, with a probability of success of 0.996. Pathway 3 (immediate surgery) was not cost-effective. Sensitivity analyses identified that the use of the highest cost estimates results in a similar overall picture. While the estimates of cost per quality-adjusted life year are higher, the economic model demonstrated that stepped approaches based on initial treatment with nonopioids are likely to represent the most cost-effective regimens for the treatment of sciatica. However, development of alternative economic modelling approaches is required.

Background. This study aims to describe the healthcare resource utilization and costs of managing renal posttransplant patients over 3 years posttransplant in nine European countries and to stratify them by year 1 glomerular filtration rate (GFR). Methods. A retrospective observational and database analysis of renal transplant patients and a physician questionnaire study were conducted to collect recipient and donor characteristics, posttransplant events, and healthcare resource utilization related to these posttransplant events. In each country, local published costs were applied to the resource use identified. The results were stratified by the patient GFR reading at a time point 1 year after renal transplant. Results. The database study identified 3,181 patients who met the inclusion criteria, along with 2,818 transplants carried out in the centers surveyed by questionnaire. Total 3-year costs derived from the questionnaire analysis vary depending on local treatment practices, from a minimum of €33,602 per patient in the Czech Republic to €77,461 per patient in the Netherlands. Consistently across countries, estimated costs appear to decrease with improved graft functioning status (increased GFR) at 1 year. The average 3-year costs, discounting immunosuppresion therapy and certain posttransplant events, per patient with a GFR greater than or equal to 60 at 1 year are estimated to be around 35% lower than those with 15eGFRG30. Conclusion. This study demonstrates that in Europe, worsening posttransplant renal function may contribute to substantive increases in resource use, with some variation across regions. Therefore, management strategies that promote renal function after transplantation have the potential to provide important resource savings.

Background: Tumour gene expression analysis is useful in predicting adjuvant chemotherapy benefit in early breast cancer patients. This study aims to examine the implications of routine Oncotype DX testing in the UK. Methods: Women with oestrogen receptor positive (ER+), pNO or pN1mi breast cancer were assessed for adjuvant chemotherapy and subsequently offered Oncotype DX testing, with changes in chemotherapy decisions recorded. A subset of patients completed questionnaires about their uncertainties regarding chemotherapy decisions pre- and post-testing. All patients were asked to complete a diary of medical interactions over the next 6 months, from which economic data were extracted to model the cost-effectiveness of testing. Results: Oncotype DX testing resulted in changes in chemotherapy decisions in 38 of 142 (26.8%) women, with 26 of 57 (45.6%) spared chemotherapy and 12 of 85 (14.1%) requiring chemotherapy when not initially recommended (9.9% reduction overall). Decision conflict analysis showed that Oncotype DX testing increased patients' confidence in treatment decision making. Economic analysis showed that routine Oncotype DX testing costs £6232 per quality-adjusted life year gained. Conclusion: Oncotype DX decreased chemotherapy use and increased confidence in treatment decision making in patients with ER+ early-stage breast cancer. Based on these findings, Oncotype DX is cost-effective in the UK setting.

This article compares the welfare markets in primary health care and ‘welfare‐to‐work’ in the UK since the late 1990s. A longitudinal comparison of two different policy areas enables us to study the context in which marketization and the resulting shift of welfare provision takes place. We outline the general background of the market‐based reforms and highlight in what way policymakers have ascribed third sector organizations (TSOs) a number of positive characteristics, particularly the ability to address concerns about well‐known market failures. While consecutive governments promoted these organizations as welfare providers, case studies of two illustrative provider organizations in each policy area reveal a number of problems regarding their distinctiveness in increasingly competitive welfare markets.We conclude that the crisp distinction made by policymakers between the third and other sectors as well as the alleged advantages of the former present a rather naïve picture of a complex reality and argue for a more critical view of third sector characteristics and performance. The third sector is not only characterized by a high degree of fuzziness at the boundaries to other sectors, but even within single organizations, which often undergo significant transformations over time. As a result, policy intentions and practical outcomes are contradictory with TSOs losing their alleged distinctiveness as players in increasingly competitive markets. Furthermore, we contend that detailed longitudinal studies of organizations are essential in the advancement of the discussion of the third sector concept as they provide conceptual insights into organizational change and behaviour.

Objective This study aimed to determine the cost-effectiveness of daclatasvir in combination with other medicinal products for the treatment of patients with hepatitis C virus genotypes 1 and 4 and advanced liver disease in the UK. Methods A published and validated Markov model designed to simulate the natural history of chronic hepatitis C was used to compare daclatasvir with relevant treatment options for patients with hepatitis C virus genotypes 1 and 4 and a METAVIR score of F3-F4. Patients were defined according to their treatment status; that is, naive, experienced or interferon ineligible/intolerant. Data inputs for the analysis were derived from published sources, UK-specific where possible. A lifetime horizon was used, with costs and benefits discounted at 3.5%. Results Daclatasvir-based regimens are estimated to be cost-effective versus no treatment and established standard-of-care regimens, including telaprevir in combination with pegylated interferon-α+ribavirin (PR), boceprevir in combination with PR and PR alone (incremental cost-effectiveness ratio range: £3715-£15,408). The cost-effectiveness of daclatasvir-based regimens versus emerging regimens (sofosbuvir or simeprevir based) is less consistent, but was dominant or cost-effective (incremental cost-effectiveness ratio range: £1394-£28,393) in all except two scenarios. Conclusion Daclatasvir-based regimens are expected to be highly cost-effective for the majority patients with advanced disease versus relevant comparator regimens, including newer direct-acting antiviral regimens.

Introduction Hepatitis C virus (HCV) infection is one of the principle causes of chronic liver disease. Successful treatment significantly decreases the risk of hepatic morbidity and mortality. Current standard of care achieves sustained virologic response (SVR) rates of 40–80%; however, the HCV therapy landscape is rapidly evolving. The objective of this study was to quantify the clinical and economic benefit associated with increasing levels of SVR. Methods A published Markov model (MONARCH) that simulates the natural history of hepatitis C over a lifetime horizon was used. Discounted and non-discounted life-years (LYs), quality-adjusted life-years (QALYs) and cost of complication management were estimated for various plausible SVR rates. To demonstrate the robustness of projections obtained, the model was validated to ten UK-specific HCV studies. Results QALY estimates ranged from 18.0 years for those treated successfully in fibrosis stage F0 to 7.5 years (discounted) for patients in fibrosis stage F4 who remain untreated. Predicted QALY gains per 10% improvement in SVR ranged from 0.23 (F0) to 0.64 (F4) and 0.58 (F0) to 1.35 (F4) in 40 year old patients (discounted and non-discounted results respectively). In those aged 40, projected discounted HCV-related costs are minimised with successful treatment in F0/F1 (at approximately £300), increasing to £49,300 in F4 patients who remain untreated. Validation of the model to published UK cost-effectiveness studies produce R2 goodness of fit statistics of 0.988, 0.978 and of 0.973 for total costs, QALYs and incremental cost effectiveness ratios, respectively. Conclusion Projecting the long-term clinical and economic consequences associated with chronic hepatitis C is a necessary requirement for the evaluation of new treatments. The principle analysis demonstrates the significant impact on expected costs, LYs and QALYs associated with increasing SVR. A validation analysis demonstrated the robustness of the results reported.

Economic evaluations of new diabetes therapies rely heavily upon the UK Prospective Diabetes Study (UKPDS) equations for prediction of cardiovascular events; however, concerns persist regarding their relevance to current clinical practice and appropriate use in populations other than newly diagnosed patients. This study refits the UKPDS 68 event equations, using contemporary data describing low- and intermediate-risk patients. Anonymized patient data describing demographics, risk factors and incidence of cardiovascular and microvascular events were extracted from The Health Improvement Network (THIN) database over the 10-year period from 1 January 2000 to 31 December 2009. Following multiple imputation of missing values, accelerated failure-time Weibull regression equations were refitted to produce new coefficients for each risk group. Discriminatory performance was assessed and compared with both UKPDS 68 and UKPDS 82 risk equations, and the implication of coefficient choice within an economic evaluation was assessed using the Cardiff type 2 diabetes model. When applied to patient-level data, the three sets of coefficients (UKPDS, THIN low-risk and intermediate-risk) lead to fairly consistent predictions of the 5-year risk of events. Exceptions include lower predicted rates of myocardial infarction and higher rates of ischaemic heart disease, congestive heart failure and end-stage renal disease with both sets of revised THIN coefficients compared with UKPDS. Over a modelled lifetime, the coefficients derived from the low-risk data predict fewer total cardiovascular events compared with UKPDS, while those from the intermediate-risk data predict a greater number. The areas under the receiver–operating characteristic curves demonstrated a marginal improvement in the discriminatory performance of the refitted equations. The incremental cost-effectiveness ratio associated with dapagliflozin versus sulphonylurea in addition to metformin changed from £7,708 to £7,519 and £6,906 per QALY gained, using the THIN intermediate- and low-risk coefficients, respectively. The results suggest that while the UKPDS equations perform best in newly diagnosed patients, they may overpredict the lifetime risk in this group and underpredict it in patients with more advanced diabetes. Implementation of the revised coefficients will result in different absolute numbers of predicted diabetes-related events; however, they are not expected to significantly affect the conclusions of economic modelling.

Background & Aims This study aims to assess the cost-effectiveness of a routine universal antenatal hepatitis C virus (HCV) screening programme at a London centre. Methods Ten years' retrospective antenatal screening and outcome data informed a cost-effectiveness analysis using the previously validated MONARCH model. The cost and quality of life outcomes associated with the screening and treatment of newly identified hepatitis C cases were used to generate cost-effectiveness estimates for the screening programme. Results A total of 35,355 women were screened between 1st November 2003 and 1st March 2013; 136 women (0.38%) were found to be HCV antibody positive. Of 78 (0.22%) viraemic cases, 44 (0.12%) were newly diagnosed. In addition, the screening programme identified three (6.8%) vertical transmissions in children of newly diagnosed mothers. Of 16 newly diagnosed mothers biopsied, all were in the F0-F2 METAVIR disease stages, and 50% had HCV genotype 1. Postnatal treatment with pegylated interferon and ribavirin was initiated in 19 women, with 14 (74%) achieving sustained virologic response. The total cost of screening and confirmation of diagnoses was estimated to be £240,641. This translates to £5469 per newly diagnosed individual. The incremental cost-effectiveness ratio of this screening and treatment strategy was £2400 per QALY gained. Treatment with newer direct-acting antiviral regimens would have a projected cost of £9139 per QALY gained, well below the £20,000-30,000/QALY gained willingness-to-pay threshold applied by policy advisory bodies. Conclusions This study demonstrates that an antenatal screening and treatment programme is feasible and effective, at a cost considered acceptable.

Introduction Type 2 diabetes mellitus (T2DM) is an increasing problem worldwide and a leading risk factor for cardiovascular disease. As beta cell function declines, the management of T2DM typically comprises of escalations in treatment from diet and exercise to oral therapies and eventually insulin. Treatment algorithms based on the attainment of blood glucose targets may not account for changes in other cardiovascular risk factors. The objective of this study is to describe unmet clinical need, defined as failure to reduce weight or meet targets for blood pressure, total cholesterol or glycated hemoglobin (HbA1c) levels. Methods Anonymized UK patient data for those (1) initiating oral antidiabetic drug (OAD) monotherapy, (2) escalating to dual therapy, (3) escalating to triple therapy, and (4) escalating to insulin therapy over the study period (01/01/2005–31/12/2009) were obtained from The Health Improvement Network (THIN). Changes in risk factors were evaluated before and after therapy escalation, and the attainment of targets, assessed at the last recorded measurement, as follows: HbA1c

Summary Hereditary angioedema (HAE) and acquired angioedema (AAE) are rare life-threatening conditions caused by deficiency of C1 inhibitor (C1INH). Both are characterized by recurrent unpredictable episodes of mucosal swelling involving three main areas: the skin, gastrointestinal tract and larynx. Swelling in the gastrointestinal tract results in abdominal pain and vomiting, while swelling in the larynx may be fatal. There are limited UK data on these patients to help improve practice and understand more clearly the burden of disease. An audit tool was designed, informed by the published UK consensus document and clinical practice, and sent to clinicians involved in the care of HAE patients through a number of national organizations. Data sets on 376 patients were received from 14 centres in England, Scotland and Wales. There were 55 deaths from HAE in 33 families, emphasizing the potentially lethal nature of this disease. These data also show that there is a significant diagnostic delay of on average 10 years for type I HAE, 18 years for type II HAE and 5 years for AAE. For HAE the average annual frequency of swellings per patient affecting the periphery was eight, abdomen 5 and airway 0·5, with wide individual variation. The impact on quality of life was rated as moderate or severe by 37% of adult patients. The audit has helped to define the burden of disease in the UK and has aided planning new treatments for UK patients.

Objective To assess the overall cost effectiveness of the NHS breast screening programme, based on findings of the Independent UK Panel on Breast Cancer Screening and taking into account the uncertainty of associated estimates of benefits, harms, and costs. Design A life table model comparing data from two cohorts. Setting United Kingdom’s health service. Participants and interventions 364 500 women aged 50 years—the population of 50 year old women in England and Wales who would be eligible for screening—were followed up for 35 years without screening, compared with a similar cohort who had regular mammographic screening between ages 50 and 70 years and were then followed for another 15 years. Main outcome measures Between the cohorts, we compared the number of breast cancer diagnoses, number of deaths from breast cancer, number of deaths from other causes, person years of survival adjusted for health quality, and person years of survival with breast cancer. We also calculated the costs of treating primary and end stage breast cancer, and the costs of screening. Probabilistic sensitivity analysis explored the effect of uncertainty in key input parameters on the model outputs. Results Under the base case scenario (using input parameters derived from the Independent Panel Review), there were 1521 fewer deaths from breast cancer and 2722 overdiagnosed breast cancers. Discounting future costs and benefits at a rate of 3.5% resulted in an additional 6907 person years of survival in the screened cohort, at a cost of 40 946 additional years of survival after a diagnosis of breast cancer. Screening was associated with 2040 additional quality adjusted life years (QALYs) at an additional cost of £42.5m (€49.8m; $64.7m) in total or £20 800 per QALY gained. The gain in person time survival over 35 years was 9.2 days per person and 2.7 quality adjusted days per person screened. Probabilistic sensitivity analysis showed that this incremental cost effectiveness ratio varied widely across a range of plausible scenarios. Screening was cost effective at a threshold of £20 000 per QALY gained in 2260 (45%) scenarios, but in 588 (12%) scenarios, screening was associated with a reduction in QALYs. Conclusion The NHS breast screening programme is only moderately likely to be cost effective at a standard threshold. However, there is substantial uncertainty in the model parameter estimates, and further primary research will be needed for cost effectiveness studies to provide definitive data to inform policy.

Organisations are never static; they are changing all the time. Unsurprisingly, actors in ‘third sector organisations’ (the diverse array of organisations that do not fit into the ideal type constructs of market or state organisations) experience and implement change in many different ways. On the one hand, there are numerous types of third sector organisations operating in different policy streams, locations, and contexts. On the other, third sector organisations engage in a variety of activities; some may deliver public service contracts, whilst others focus on traditional civil society and volunteer based activities. Many more may sit somewhere in between (Billis, 2010).

Often it is mentioned by participants that having peers speak out about their personal journey has instilled a sense of hope and been an inspiring experience. From this evolved the Mentor program. The Body Image and Eating Disorders Treatment and Recovery Service (BETRS) Mentor Program has been developed to complement the professional expertise within the team. Our Mentors share their lived experience of an eating disorder with current patients of BETRS. The invaluable contribution to the service by our mentors has been the following: - Supporting hopefulness and the recovery process by co-facilitating group sessions that focus on how they dealt with issues that are of particular concern to current patients. - Strengthen relapse prevention by giving firsthand accounts of occasions when lapses have not signalled a relapse but have been incorporated into the recovery process. - Mentors have been fostering motivation by encouraging behaviours that supported their own recovery and by assisting with the organisation and general care of the client group. - By sharing their experience of having an eating disorder and providing evidence of hope during the course of recovery mentors have given family and carers and better understanding. This abstract was presented in the Care in Inpatient and Community Settings stream of the 2013 ANZAED Conference.
