Background There has been a steady increase in the number of primary care patients receiving long-term maintenance antidepressant treatment, despite limited evidence of a benefit of this treatment beyond 8 months. Objective The ANTidepressants to prevent reLapse in dEpRession (ANTLER) trial investigated the clinical effectiveness and cost-effectiveness of antidepressant medication in preventing relapse in UK primary care. Design This was a Phase IV, double-blind, pragmatic, multisite, individually randomised parallel-group controlled trial, with follow-up at 6, 12, 26, 39 and 52 weeks. Participants were randomised using minimisation on centre, type of antidepressant and baseline depressive symptom score above or below the median using Clinical Interview Schedule – Revised (two categories). Statisticians were blind to allocation for the outcome analyses. Setting General practices in London, Bristol, Southampton and York. Participants Individuals aged 18–74 years who had experienced at least two episodes of depression and had been taking antidepressants for ≥ 9 months but felt well enough to consider stopping their medication. Those who met an International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, diagnosis of depression or with other psychiatric conditions were excluded. Intervention At baseline, participants were taking citalopram 20 mg, sertraline 100 mg, fluoxetine 20 mg or mirtazapine 30 mg. They were randomised to either remain on their current medication or discontinue medication after a tapering period. Main outcome measures The primary outcome was the time, in weeks, to the beginning of the first depressive episode after randomisation. This was measured by a retrospective Clinical Interview Schedule – Revised that assessed the onset of a depressive episode in the previous 12 weeks, and was conducted at 12, 26, 39 and 52 weeks. The depression-related resource use was collected over 12 months from medical records and patient-completed questionnaires. Quality-adjusted life-years were calculated using the EuroQol-5 Dimensions, five-level version. Results Between 9 March 2017 and 1 March 2019, we randomised 238 participants to antidepressant continuation (the maintenance group) and 240 participants to antidepressant discontinuation (the discontinuation group). The time to relapse of depression was shorter in the discontinuation group, with a hazard ratio of 2.06 (95% confidence interval 1.56 to 2.70; p < 0.0001). By 52 weeks, relapse was experienced by 39% of those who continued antidepressants and 56% of those who discontinued antidepressants. The secondary analysis revealed that people who discontinued experienced more withdrawal symptoms than those who remained on medication, with the largest difference at 12 weeks. In the discontinuation group, 37% (95% confidence interval 28% to 45%) of participants remained on their randomised medication until the end of the trial. In total, 39% (95% confidence interval 32% to 45%) of participants in the discontinuation group returned to their original antidepressant compared with 20% (95% confidence interval 15% to 25%) of participants in maintenance group. The health economic evaluation demonstrated that participants randomised to discontinuation had worse utility scores at 3 months (–0.037, 95% confidence interval –0.059 to –0.015) and fewer quality-adjusted life-years over 12 months (–0.019, 95% confidence interval –0.035 to –0.003) than those randomised to continuation. The discontinuation pathway, besides giving worse outcomes, also cost more [extra £2.71 per patient over 12 months (95% confidence interval –£36.10 to £37.07)] than the continuation pathway, although the cost difference was not significant. Conclusions Patients who discontinue long-term maintenance antidepressants in primary care are at increased risk of relapse and withdrawal symptoms. However, a substantial proportion of patients can discontinue antidepressants without relapse. Our findings will give patients and clinicians an estimate of the likely benefits and harms of stopping long-term maintenance antidepressants and improve shared decision-making. The participants may not have been representative of all people on long-term maintenance treatment and we could study only a restricted range of antidepressants and doses. Identifying patients who will not relapse if they discontinued antidepressants would be clinically important. Trial registration Current Controlled Trials ISRCTN15969819 and EudraCT 2015-004210-26.

<p><strong>Introduction:</strong> Venous thromboembolism is a burden on healthcare systems. The aim of this analysis was to project the long-term costs and outcomes for rivaroxaban compared to standard of care (enoxaparin/warfarin) in Portugal for the treatment and secondary prevention of venous thromboembolism.<br /><strong>Material and Methods:</strong> A Markov model was developed using event rates extracted from the EINSTEIN trials supplemented with literature-based estimates of longer-term outcomes. Core outcomes included per patient costs and quality-adjusted life years reported separately per treatment arm and incrementally, as well as cost per quality-adjusted life years gained. The deep vein thrombosis and pulmonary embolism indications were analysed separately. The analyses were conducted from the Portuguese societal perspective and over a 5-year time horizon. Costs and outcomes were discounted at a 5% annual rate. Several scenario analyses were undertaken to explore the impact on results of varying key modeling assumptions.<br /><strong>Results:</strong> Rivaroxaban treatment was associated with cost-savings for the treatment of deep vein thrombosis and was both cost-saving and more effective for the treatment of pulmonary embolism, compared with enoxaparin/warfarin.<br /><strong>Discussion:</strong> The results of the sensitivity and scenario analyses further supported that rivaroxaban is a cost-effective alternative to standard of care treatment. The use of an expert panel to derive some input values and the lack of Portuguese specific utilities were the main limitations.<br /><strong>Conclusion:</strong> Rivaroxaban represents an efficient alternative to using enoxaparin/warfarin in Portugal, as it’s associated with lower costs (for both indications) and greater quality adjusted life years (for the pulmonary embolism indication).</p><p><br /><strong>Keywords: </strong>Venous Thrombosis; Pulmonary Embolism; Rivaroxaban; Venous Thromboembolism.</p>

ObjectiveTo compare the long-term economic impact of melanoma prevention by sun protection, with the corresponding impact of early detection of melanoma to decrease melanoma deaths.DesignCost-effectiveness analysis using Markov cohort model. Data were primarily from two population-based randomised controlled trials, epidemiological and costing reports, and included flow-on effects for keratinocyte cancers (previously non-melanoma skin cancers) and actinic keratoses.SettingQueensland, Australia.ParticipantsMen and women with a mean age 50 years modelled for 30 years.InterventionsDaily sunscreen use (prevention) compared with annual clinical skin examinations (early detection) and comparing these in turn with the status quo.Primary and secondary outcomesCosts, counts of melanoma, melanoma deaths, keratinocyte cancers, life years and quality-adjusted life years.ResultsPer 100 000 individuals, for early detection, primary prevention and without intervention, there were 2446, 1364 and 2419 new melanomas, 556, 341 and 567 melanoma deaths, 64 452, 47 682 and 64 659 keratinocyte cancers and £493.5, £386.4 and £406.1 million in economic costs, respectively. There were small differences between prevention and early detection in life years saved (0.09%) and quality-adjusted life years gained (0.10%).ConclusionsCompared with early detection of melanoma, systematic sunscreen use at a population level will prevent substantial numbers of new skin tumours, melanoma deaths and save healthcare costs. Primary prevention through daily use of sunscreen is a priority for investment in the control of melanoma.

Background Cost-effectiveness analysis using quality-adjusted life-years as the measure of health benefit is commonly used to aid decision-makers. Clinical studies often do not include preference-based measures that allow the calculation of quality-adjusted life-years, or the data are insufficient. ‘Mapping’ can bridge this evidence gap; it entails estimating the relationship between outcomes measured in clinical studies and the required preference-based measures using a different data set. However, many methods for mapping yield biased results, distorting cost-effectiveness estimates. Objectives Develop existing and new methods for mapping; test their performance in case studies spanning different preference-based measures; and develop methods for mapping between preference-based measures. Data sources Fifteen data sets for mapping from non-preference-based measures to preference-based measures for patients with head injury, breast cancer, asthma, heart disease, knee surgery and varicose veins were used. Four preference-based measures were covered: the EuroQoL-5 Dimensions, three-level version (n = 11), EuroQoL-5 Dimensions, five-level version (n = 2), Short Form questionnaire-6 Dimensions (n = 1) and Health Utility Index Mark 3 (n = 1). Sample sizes ranged from 852 to 136,327. For mapping between generic preference-based measures, data from FORWARD, the National Databank for Rheumatic Diseases (which includes the EuroQoL-5 Dimensions, three-level version, and EuroQoL-5 Dimensions, five-level version, in its 2011 wave), were used. Main methods developed Mixture-model-based approaches for direct mapping, in which the dependent variable is the health utility value, including adaptations of methods developed to model the EuroQoL-5 Dimensions, three-level version, and beta regression mixtures, were developed, as were indirect methods, in which responses to the descriptive systems are modelled, for consistent multidirectional mapping between preference-based measures. A highly flexible approach was designed, using copulas to specify the bivariate distribution of each pair of EuroQoL-5 Dimensions, three-level version, and EuroQoL-5 Dimensions, five-level version, responses. Results A range of criteria for assessing model performance is proposed. Theoretically, linear regression is inappropriate for mapping. Case studies confirm this. Flexible, direct mapping methods, based on different variants of mixture models with appropriate underlying distributions, perform very well for all preference-based measures. The precise form is important. Case studies show that a minimum of three components are required. Covariates representing disease severity are required as predictors of component membership. Beta-based mixtures perform similarly to the bespoke mixture approaches but necessitate detailed consideration of the number and location of probability masses. The flexible, bi-directional indirect approach performs well for testing differences between preference-based measures. Limitations Case studies drew heavily on EuroQoL-5 Dimensions. Indirect methods could not be undertaken for several case studies because of a lack of coverage. These methods will often be unfeasible for preference-based measures with complex descriptive systems. Conclusions Mapping requires appropriate methods to yield reliable results. Evidence shows that widely used methods such as linear regression are inappropriate. More flexible methods developed specifically for mapping show that close-fitting results can be achieved. Approaches based on mixture models are appropriate for all preference-based measures. Some features are universally required (such as the minimum number of components) but others must be assessed on a case-by-case basis (such as the location and number of probability mass points). Future research priorities Further research is recommended on (1) the use of the monotonicity concept, (2) the mismatch of trial and mapping distributions and measurement error and (3) the development of indirect methods drawing on methods developed for mapping between preference-based measures.

ObjectiveTo estimate the costs and outcomes associated with treating non-asthmatic adults (nor suffering from other lung-disease) presenting to primary care with acute lower respiratory tract infection (ALRTI) with oral corticosteroids compared with placebo.DesignCost-consequence analysis alongside a randomised controlled trial. Perspectives included the healthcare provider, patients and productivity losses associated with time off work.SettingFifty-four National Health Service (NHS) general practices in England.Participants398 adults attending NHS primary practices with ALRTI but no asthma or other chronic lung disease, followed up for 28 days.Interventions2× 20 mg oral prednisolone per day for 5 days versus matching placebo tablets.Outcome measuresQuality-adjusted life years using the 5-level EuroQol-5D version measured weekly; duration and severity of symptom. Direct and indirect resources related to the disease and its treatment were also collected. Outcomes were measured for the 28-day follow-up.Results198 (50%) patients received the intervention (prednisolone) and 200 (50%) received placebo. NHS costs were dominated by primary care contacts, higher with placebo than with prednisolone (£13.11 vs £10.38) but without evidence of a difference (95% CI £3.05 to £8.52). The trial medication cost of £1.96 per patient would have been recouped in prescription charges of £4.30 per patient overall (55% participants would have paid £7.85), giving an overall mean ‘profit’ to the NHS of £7.00 (95% CI £0.50 to £17.08) per patient. There was a quality adjusted life years gain of 0.03 (95% CI 0.01 to 0.05) equating to half a day of perfect health favouring the prednisolone patients; there was no difference in duration of cough or severity of symptoms.ConclusionsThe use of prednisolone for non-asthmatic adults with ALRTI, provided small gains in quality of life and cost savings driven by prescription charges. Considering the results of the economic evaluation and possible side effects of corticosteroids, the short-term benefits may not outweigh the long-term harms.Trial registration numbersEudraCT 2012-000851-15 and ISRCTN57309858; Pre-results.

Abstract Abstract 2475 Poster Board II-452 Introduction: Non-Hodgkin Lymphoma (NHL) is the fifth most common type of malignancy in Canada. The most common subtype of NHL is diffuse large B-cell lymphoma (DLBCL). Initial standard treatment for DLBCL includes combination immuno-chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP). This regimen is typically administered every 21 days for a total of 6 cycles. Febrile neutropenia (FN) is a serious toxicity of lymphoma chemotherapy and patients with this condition must be treated aggressively as it could lead to complications such as prolonged hospitalization and death. Granulocyte-colony stimulating factors such as filgrastim and pegfilgrastim are efficacious in preventing FN, yet their cost-effectiveness has not been evaluated in the publicly funded Canadian healthcare system. Methods: A Markov model was constructed to evaluate the cost-effectiveness (cost-utility) of filgrastim and pegfilgrastim as primary prophylaxis versus no primary prophylaxis against FN in DLBCL patients receiving induction chemotherapy. Health states included in the model were hospitalization for FN, and receiving chemotherapy with no FN. It was assumed that patients in the no primary prophylaxis arm of the model who experienced a FN episode would receive secondary prophylaxis with filgrastim for all subsequent chemotherapy cycles. The time horizon of the model was 18 weeks, the time period over which the six cycles of chemotherapy are administered. The analysis was conducted from the hospital perspective. Costs are reported in 2009 Canadian dollars and outcomes in quality-adjusted life years (QALY). One-way sensitivity analyses were done on model parameters. A probabilistic sensitivity analysis was done to evaluate overall uncertainty in the model. Results: In the base case analysis costs associated with the no primary prophylaxis, filgrastim and pegfilgrastim interventions were $6044, $9450 and $15899, respectively. Quality-adjusted life years associated with the three interventions were 0.198, 0.200, and 0.202 respectively (over the 18-week model time horizon). The incremental cost-effectiveness ratio (ICER) of filgrastim compared to no primary prophylaxis was estimated to be $1.7 million (M)/QALY [95% confidence interval: -14M/QALY (dominated) to $15M/QALY]; for pegfilgrastim compared to filgrastim the ICER was estimated to be $4.4M/QALY [95% confidence interval: -25M/QALY (dominated) to $22.7M/QALY]. All one-way sensitivity analyses yielded ICERs of greater than $1M/QALY. Conclusions: The ICERs for filgrastim and pegfilgrastim when used as primary prophylaxis against FN in DLBCL patients receiving induction chemotherapy are well above the usually accepted cost-effectiveness threshold of $50,000/QALY.

Background: Psychological distress is highly prevalent among patients with metastatic colorectal cancer. Aims: To perform an economic evaluation of a combined screening and treatment program targeting psychological distress in patients with metastatic colorectal cancer in comparison with usual care. Design: Societal costs were collected alongside a cluster randomized controlled trial for 48 weeks. A total of 349 participants were included. Setting: Participants were recruited from oncology departments at 16 participating hospitals in the Netherlands. Methods: Outcome measures were the Hospital Anxiety and Depression Scale and quality-adjusted life-years. Missing data were imputed using multiple imputation. Uncertainty was estimated using bootstrapping. Cost-effectiveness planes and cost-effectiveness acceptability curves were estimated to show uncertainty surrounding the cost-effectiveness estimates. Sensitivity analyses were performed to check robustness of results. Results: Between treatment arms, no significant differences were found in Hospital Anxiety and Depression Scale score (mean difference: –0.058; 95% confidence interval: –0.13 to 0.011), quality-adjusted life-years (mean difference: 0.042; 95% confidence interval: –0.015 to 0.099), and societal costs (mean difference: –1152; 95% confidence interval: –5058 to 2214). Cost-effectiveness acceptability curves showed that the probability of cost-effectiveness was 0.64 and 0.74 at willingness-to-pay values of €0 and €10,000 per point improvement on the Hospital Anxiety and Depression Scale, respectively. The probability that the intervention was cost-effective compared to usual care for quality-adjusted life-years was 0.64 and 0.79 at willingness-to-pay values of €0 and €20,000 per quality-adjusted life-year, respectively. Conclusion: The intervention is dominant over usual care, primarily due to lower costs in the intervention group. However, there were no statistically significant differences in clinical effects and the uptake of the intervention was quite low. Therefore, widespread implementation cannot be recommended.

Lo scopo di questo studio è valutare la qualità di vita percepita dalle persone sottoposte a terapia dialitica in rapporto al costoutilità; I pazienti oggetto dello studio a Tivoli sono stati 28, mentre a Guidonia sono stati 82. In base alla ricerca bibliografica abbiamo scelto di utilizzare l'ACU (analisi costo/utilità), tecnica che massimizza il rapporto utilità/costo, due alternative (interventi tecnici) in cui l'utilità è espressa in termini fisici e, in particolare, in termini di QALYs (quality adjusted life years) cioè anni di vita guadagnati ponderati per la qualità della vita per due diverse tecniche dialitiche: emodialisi standard HD ed emodiafiltrazione HDF. Osservando i dati emersi dallo studio ci siamo resi conto che i due gruppi percepiscono la qualità della loro vita in maniera molto simile, nonostante i parametri dialitici ed ematologici, oggetto di studio, siano significativamente migliori nel gruppo in trattamento dialitico con la metodica deU'Emodiafiltrazione.
