RESUMO
OBJECTIVE: Medication non-adherence in mental health problems has social and economic costs. The objective of the study was to review the cost-effectiveness of interventions to enhance medication adherence in patients with mental health problems. METHODS: The update of a previous systematic review was performed. Databases were searched in June 2019: MEDLINE, PSYCINFO, EMBASE, CINAHL, CRD, WOS. Cost-effectiveness studies comparing an intervention to improve the medication adherence with other interventions/usual care in adults with mental health problems were included. Data were extracted, methodological quality of the studies was assessed and a narrative synthesis was performed. RESULTS: Nine studies were included in the review. The interventions that showed medication adherence increase were: a financial incentive when depot injection was taken by patients with psychotic disorders, a value-based benefit design policy including copayment and counselling in a company setting, and a medication treatment decision supported by a pharmacogenetic test. The other studies (coaching by pharmacists; a psychological and educational intervention at health care centres) did not find differences between groups. No study found cost differences between alternatives. CONCLUSIONS: Interventions to improve medication adherence in adults with mental health problems could be cost-effective, especially those based on financial incentives, although more research is needed. KEYPOINTS There are several types of interventions designed to enhance medication adherence in patients with mental health problems. Few of them have demonstrated cost-effectiveness. Two studies found that a financial incentive per depot injection in patients with psychotic disorders improved the medication adherence. Two other studies found improvement in adherence due to two specific interventions: a value-based benefit design policy in a company setting and a pharmacogenetic test supporting the medication treatment decision. No study found differences in costs between the intervention and the comparator. More research is needed to implement cost-effective interventions.

BACKGROUND: Many health care systems claim to incorporate the cost-effectiveness criterion in their investment decisions. Information on the system's willingness to pay per effectiveness unit, normally measured as quality-adjusted life-years (QALYs), however, is not available in most countries. This is partly because of the controversy that remains around the use of a cost-effectiveness threshold, about what the threshold ought to represent, and about the appropriate methodology to arrive at a threshold value. OBJECTIVES: The aim of this article was to identify and critically appraise the conceptual perspectives and methodologies used to date to estimate the cost-effectiveness threshold. METHODS: We provided an in-depth discussion of different conceptual views and undertook a systematic review of empirical analyses. Identified studies were categorized into the two main conceptual perspectives that argue that the threshold should reflect 1) the value that society places on a QALY and 2) the opportunity cost of investment to the system given budget constraints. RESULTS: These studies showed different underpinning assumptions, strengths, and limitations, which are highlighted and discussed. Furthermore, this review allowed us to compare the cost-effectiveness threshold estimates derived from different types of studies. We found that thresholds based on society's valuation of a QALY are generally larger than thresholds resulting from estimating the opportunity cost to the health care system. CONCLUSIONS: This implies that some interventions with positive social net benefits, as informed by individuals' preferences, might not be an appropriate use of resources under fixed budget constraints.

Background: Foley catheters have been subject to limited development in the last few decades. They fulfil their basic function of draining urine from the bladder but cause other associated problems. T-Control is a new silicone Foley catheter with an integrated fluid control valve whose design aims to reduce the risks associated with bladder catheterization by a multifactorial approach. The general purpose of this study is to determine the effectiveness, comfort, and experience of the patient catheterized with T-Control® compared with patients with a conventional Foley catheter. Study Design: This trial is a mixed-method study comprising a two-arm, pilot comparative study with random allocation to T-Control catheter or traditional Foley catheter in patients with long-term catheterization and a study with qualitative methodology, through discussion groups. Endpoints: The comfort and acceptability of the T-Control® device (qualitative) and the quality of life related to self-perceived health (quantitative) will be analysed as primary endpoints. As secondary endpoints, the following will be analysed: magnitude and rate of infections (symptomatic and asymptomatic); days free of infection; indication of associated antibiotic treatments; determination of biofilm; number of catheter-related adverse events; use of each type of catheterization's healthcare resources; and level of satisfaction and workload of health professionals. Patients and Methods: Eligible patients are male and female adults aged ≥18 years, who require a change of long-term bladder catheter. The estimated sample size is 50 patients. Patient follow-up includes both the time of catheter insertion and its removal or change 4 weeks later, plus the time until the discussion groups take place.
RESUMO
Aim: To assess the effectiveness of two interventions of knowledge transfer and behavior modification to improve medication adherence in patients with depressive disorders. Methods: An open, multicenter, three-arm clinical trial with random allocation by cluster to usual care or to one of the two interventions. The intervention for psychiatrists (PsI) included an educational program based on a patient-centered care model. The intervention for patients and relatives (PtI) included a collaborative care program plus a reminder system that works using an already available medication reminder application. The primary outcome was patient adherence to antidepressant treatment assessed through the Sidorkiewicz Adherence Instrument. Secondary measures were depression severity, comorbid anxiety and health-related quality of life. Mixed regression models with repeated measures were used for data analysis. Results: Ten psychiatrists and 150 patients diagnosed with depressive disorder from eight Community Mental Health Units in the Canary Islands (Spain) were included. Compared with usual care, no differences in long-term adherence were observed in either group PsI or PtI. The PsI group had significantly improved depression symptoms (B = -0.39; 95%CI: -0.65, -0.12; p = 0.004) during the follow-up period. The PtI group presented improved depression symptoms (B = -0.63; 95%CI: -0.96, -0.30; p < 0.001) and mental quality of life (B = 0.08; 95%CI: 0.004, 0.15; p = 0.039) during the follow-up period. Conclusion: The assessed interventions to improve adherence in patients with depressive disorder were effective for depression symptoms and mental quality of life, even over the long term. However, no effect on antidepressant adherence was observed.

Background: Foley catheters have been subject to limited development in the last few decades. They fulfil their basic function of draining urine from the bladder but cause other associated problems. T-Control is a new silicone Foley catheter with an integrated fluid control valve whose design aims to reduce the risks associated with bladder catheterisation by a multifactorial approach. The general purpose of this study is to evaluate the effectiveness and cost-effectiveness of the T-Control catheter versus the Foley-type catheter in patients with Acute Urine Retention (AUR). Study design: This is a pragmatic, open, multicentre, controlled clinical trial with random allocation to the T-Control catheter or a conventional Foley-type catheter in patients with AUR. Endpoints: The magnitude of infections will be analysed as a primary endpoint. While as secondary endpoint, the following will be analysed: rate of symptomatic and asymptomatic infections; days free of infection; quality of life-related to self-perceived health; indication of associated antibiotic treatments; determination of biofilm; number of catheter-related adverse events; use of each type of catheterisation's healthcare resources; level of satisfaction and workload of health professionals and acceptability of the T-Control device as well as the patient experience. Patients and methods: Eligible patients are male adults aged ≥50 years, with AUR and with an indication of bladder catheterisation for at least 2 weeks. The estimated sample size is 50 patients. Patient follow-up includes both the time of catheter insertion and its removal or change 2 weeks later, plus 2 weeks after this time when the patient will be called for an in-depth interview.
RESUMO
OBJECTIVE: To evaluate the cost-effectiveness of infant universal vaccination against hepatitis A in Spain. METHOD: Using a dynamic model and decision tree model, a cost-effectiveness analysis was performed to compare three vaccination strategies against hepatitis A: non-vaccination strategy versus universal childhood vaccination of hepatitis A with one or two doses. The perspective of the study was that of the National Health System (NHS) and a lifetime horizon was considered. Both costs and effects were discounted at 3% per year. Health outcomes were measured in terms of quality adjusted life years (QALY) and the cost-effectiveness measure used was the incremental cost-effectiveness ratio (ICER). In addition, deterministic sensitivity analysis by scenarios was performed. RESULTS: In the particular case of Spain, with low endemicity for hepatitis A, the difference in health outcomes between vaccination strategies (with 1 or 2 doses) and non-vaccination are practically non-existent, terms of QALY. In addition, the ICER obtained is high, exceeding the limits of willingness to pay from Spain (22,000-25,000/QALY). The deterministic sensitivity analysis showed that the results are sensitive to the variations of the key parameters, although in no case the vaccination strategies are cost-effective. CONCLUSIONS: Universal infant vaccination strategy against hepatitis A would not be a cost-effective option from the NHS perspective in Spain.

OBJECTIVES: This study aimed to evaluate the effectiveness, safety and costs of FreeStyle Libre (FSL) glucose monitoring system for children and adolescents with type 1 diabetes mellitus (T1DM) in Spain. DESIGN: Prospective, multicentre pre-post study. SETTING: Thirteen Spanish public hospitals recruited patients from January 2019 to March 2020, with a 12-month follow-up. PARTICIPANTS: 156 patients were included. PRIMARY AND SECONDARY OUTCOME MEASURES: Primary: glycated haemoglobin (HbA1c) change. Secondary: severe hypoglycaemic events (self-reported and clinical records), quality of life, diabetes treatment knowledge, treatment satisfaction, adverse events, adherence, sensor usage time and scans. Healthcare resource utilisation was assessed for cost analysis from the National Health System perspective, incorporating direct healthcare costs. Data analysis used mixed regression models with repeated measures. The intervention's total cost was estimated by multiplying health resource usage with unit costs. RESULTS: In the whole sample, HbA1c increased significantly (0.32%; 95% CI 0.10% to 0.55%). In the subgroup with baseline HbA1c≥7.5% (n=88), there was a significant reduction at 3 months (-0.46%; 95% CI -0.69% to -0.23%), 6 months (-0.49%; 95% CI -0.73% to -0.25%) and 12 months (-0.43%; 95% CI -0.68% to -0.19%). Well-controlled patients had a significant 12-month worsening (0.32%; 95% CI 0.18% to 0.47%). Self-reported severe hypoglycaemia significantly decreased compared with the previous year for the whole sample (-0.37; 95% CI -0.62 to -0.11). Quality of life and diabetes treatment knowledge showed no significant differences, but satisfaction increased. Adolescents had lower sensor usage time and scans than children. Reduction in HbA1c was significantly associated with device adherence. No serious adverse effects were observed. Data suggest that use of FSL could reduce healthcare resource use (strips and lancets) and costs related to productivity loss. CONCLUSIONS: The use of FSL in young patients with T1DM was associated with a significant reduction in severe hypoglycaemia, and improved HbA1c levels were seen in patients with poor baseline control. Findings suggest cost savings and productivity gains for caregivers. Causal evidence is limited due to the study design. Further research is needed to confirm results and assess risks, especially for patients with lower baseline HbA1c.

Most of rare disease (RD) patients are assisted in their homes by their family as informal caregivers, causing a substantial burden among family members devoted to care. The role of informal caregivers has been associated with increased levels of stress, poor physical/mental health and impaired HRQOL. The present study assessed the impact on HRQOL and perceived burden of long-term informal caregiving, as well as the inter-relationships of individuals affected by different RD in six European countries, taking advantage of the data provided by the BURQOL-RD project (France, Germany, Italy, Spain, Sweden and UK). Correlation analysis was used to explore the relation between caregiver HRQOL and caregiver burden (Zarit Burden Interview). Multinomial logistic regression models were used to explore the role of explanatory variables on each domain of caregivers HRQOL measured by EQ-5D. Caregivers' HRQOL is inversely correlated with burden of caring. Mobility dimension of EQ-5D was significantly associated with patients age, time devoted to care by secondary caregivers, patient gender and patient utility index. Patients' age, burden scores and patient utility index significantly predict the capacity of caregivers to perform activities of daily living. Employed caregivers are less likely of reporting 'slight problems' in pain/discomfort dimensions than unemployed caregivers. The EQ-5D instrument is sensitive to measure differences in HRQOL between caregivers with different levels of burden of care.

BACKGROUND: When healthcare budgets are exogenous, cost-effectiveness thresholds (CETs) used to inform funding decisions should represent the health opportunity cost (HOC) of such funding decisions, but HOC-based CET estimates have not been available until recently. In recent years, empirical HOC-based CETs for multiple countries have been published, but the use of these CETs in the cost-effectiveness analysis (CEA) literature has not been investigated. Analysis of the use of HOC-based CETs by researchers undertaking CEAs in countries with different decision-making contexts will provide valuable insights to further understand barriers and facilitators to the acceptance and use of HOC-based CETs. OBJECTIVES: We aimed to identify the CET values used to interpret the results of CEAs published in the scientific literature before and after the publication of jurisdiction-specific empirical HOC-based CETs in four countries. METHODS: We undertook a scoping review of CEAs published in Spain, Australia, the Netherlands and South Africa between 2016 (2014 in Spain) and 2020. CETs used before and after publication of HOC estimates were recorded. We conducted logit regressions exploring factors explaining the use of HOC values in identified studies and linear models exploring the association of the reported CET value with study characteristics and results. RESULTS: 1171 studies were included in this review (870 CEAs and 301 study protocols). HOC values were cited in 28% of CEAs in Spain and in 11% of studies conducted in Australia, but they were not referred to in CEAs undertaken in the Netherlands and South Africa. Regression analyses on Spanish and Australian studies indicate that more recent studies, studies without a conflict of interest and studies estimating an incremental cost-effectiveness ratio (ICER) below the HOC value were more likely to use the HOC as a threshold reference. In addition, we found a small but significant impact indicating that for every dollar increase in the estimated ICER, the reported CET increased by US$0.015. Based on the findings of our review, we discuss the potential factors that might explain the lack of adoption of HOC-based CETs in the empirical CEA literature. CONCLUSIONS: The adoption of HOC-based CETs by identified published CEAs has been uneven across the four analysed countries, most likely due to underlying differences in their decision-making processes. Our results also reinforce a previous finding indicating that CETs might be endogenously selected to fit authors' conclusions.

OBJECTIVE: The aim of this scoping review was to overview the cost-of-illness studies conducted in rare diseases. METHODS: We searched papers published in English in PubMed from January 2007 to December 2018. We selected cost-of-illness studies on rare diseases defined as those with prevalence lower than 5 per 10,000 cases. Studies were selected by one researcher and verified by a second researcher. Methodological characteristics were extracted to develop a narrative synthesis. RESULTS: We included 63 cost-of-illness studies on 42 rare diseases conducted in 25 countries, and 9 systematic reviews. Most studies (94%) adopted a prevalence-based estimation, where the predominant design was cross-sectional with a bottom-up approach. Only four studies adopted an incidence-based estimation. Most studies used questionnaires to patients or caregivers to collect resource utilisation data (67%) although an important number of studies used databases or registries as a source of data (48%). Costs of lost productivity, non-medical costs and informal care costs were included in 68%, 60% and 43% of studies, respectively. CONCLUSION: This review found a paucity of cost-of-illness studies in rare diseases. However, the analysis shows that the cost-of-illness studies of rare diseases are feasible, although the main issue is the lack of primary and/or aggregated data that often prevents a reliable estimation of the economic burden.

Newborn screening programs are a fundamental tool for secondary prevention or pre-symptomatic detection of certain conditions. The implementation of a newborn screening program requires an evaluation of effectiveness, safety, cost-effectiveness, feasibility and budget impact. Economic evaluation aims to contribute to the sustainability and solvency of health systems, especially when it comes to informing about financing health interventions with public funds. This funding must be justified on the basis of robust evidence of effectiveness, safety, cost-effectiveness, and acceptability. One of the most important limitations when evaluating the cost-effectiveness of a newborn screening program for hereditary disorders or congenital errors of metabolism is the scarcity of scientific evidence that limits the robustness of the economic analysis. Given the low availability of data, the use of expert opinion as a data source is unavoidable to complete the information. However, two main problems make it difficult to synthesize data obtained from various sources: biases and heterogeneity. Moreover, the measurement of quality-adjusted life years (QALYs) in pediatric populations poses serious methodological challenges. In Spain, although there is some heterogeneity in the supply of newborn screening programs between regions, guidelines are being established based on the best available scientific evidence to achieve the homogenization of newborn screening policies and programs at national level.
Los programas de cribado neonatal son una herramienta fundamental para la prevención secundaria o detección presintomática de determinadas afecciones. La implantación de un programa de cribado neonatal requiere necesariamente de una evaluación de su efectividad, seguridad, coste-efectividad, factibilidad e impacto presupuestario. La evaluación económica pretende contribuir a la sostenibilidad y solvencia de los sistemas sanitarios, especialmente a la hora de informar sobre la posible financiación, con fondos públicos, de intervenciones sanitarias como el cribado poblacional. Esta financiación debe justificarse en base a pruebas robustas de efectividad, seguridad, coste-efectividad y aceptabilidad. Una de las limitaciones más importantes a la hora de evaluar el coste-efectividad de un programa de cribado neonatal de trastornos hereditarios o de errores congénitos del metabolismo es la escasez de evidencia científica que limita la solidez y robustez del análisis de evaluación económica. Dada la baja disponibilidad de datos, el uso de la opinión de expertos como fuente de datos es inevitable para completar la información necesaria. Sin embargo, dos problemas principales dificultan la síntesis de datos obtenidos de varias fuentes: sesgos y heterogeneidad. Por otro lado, la medición de los años de vida ajustados por calidad (AVAC) en poblaciones pediátricas plantea serios desafíos metodológicos en un análisis de evaluación económica. En España, aunque existe cierta heterogeneidad en la oferta de programas de cribado neonatal entre CC.AA., se están estableciendo directrices basadas en la mejor evidencia científica disponible para conseguir la homogeneización de políticas y programas de cribado neonatal a nivel nacional.

INTRODUCTION: Virtual Communities of Practice (VCoP) or knowledge-sharing virtual communities offer ubiquitous access to information and exchange possibilities for people in similar situations, which might be especially valuable for the self-management of patients with chronic diseases. In view of the scarce evidence on the clinical and economic impact of these interventions on chronic conditions, we aim to evaluate the effectiveness and cost-effectiveness of a VCoP in the improvement of the activation and other patient empowerment measures in patients with ischaemic heart disease (IHD). METHODS AND ANALYSIS: A pragmatic randomised controlled trial will be performed in Catalonia, Madrid and Canary Islands, Spain. Two hundred and fifty patients with a recent diagnosis of IHD attending the participating centres will be selected and randomised to the intervention or control group. The intervention group will be offered participation for 12 months in a VCoP based on a gamified web 2.0 platform where there is interaction with other patients and a multidisciplinary professional team. Intervention and control groups will receive usual care. The primary outcome will be measured with the Patient Activation Measure questionnaire at baseline, 6, 12 and 18 months. Secondary outcomes will include: clinical variables; knowledge (Questionnaire of Cardiovascular Risk Factors), attitudes (Self-efficacy Managing Chronic Disease Scale), adherence to the Mediterranean diet (Mediterranean Diet Questionnaire), level of physical activity (International Physical Activity Questionnaire), depression (Patient Health Questionnaire), anxiety (Hospital Anxiety Scale-A), medication adherence (Adherence to Refill Medication Scale), quality of life (EQ-5D-5L) and health resources use. Data will be collected from self-reported questionnaires and electronic medical records. ETHICS AND DISSEMINATION: The trial was approved by Clinical Research Ethics Committee of Gregorio Marañón University Hospital in Madrid, Nuestra Señora de Candelaria University Hospital in Santa Cruz de Tenerife and IDIAP Jordi Gol in Barcelona. The results will be disseminated through workshops, policy briefs, peer-reviewed publications, local/international conferences. TRIAL REGISTRATION NUMBER: ClinicalTrials.gov Registry (NCT03959631).

PURPOSE: Depression is a widespread mental disorder which can be treated effectively. However, low adherence to antidepressants is very common. The study of medication adherence in depression (MAPDep study) assesses the effectiveness and cost-effectiveness of a multicomponent strategy to enhance adherence toward medications in patients with depression. INTERVENTION: The intervention is a multicomponent one consisting of an educational program for psychiatrists and/or a collaborative care program for patients and relatives, plus a reminder system that works through the use of an already available high-quality medication reminder application. STUDY DESIGN: MAPDep study is an open, multicenter, four-arm cluster randomized controlled trial. The clusters are mental health units where psychiatrists are invited to participate. The clusters are randomly allocated to one of the three interventions or to usual care (control arm). Patients (18-65 years of age) diagnosed with depressive disorder, those taking antidepressant medication for an existing diagnosis of depression, and mobile phone users are selected. In group 1, only patients and relatives receive intervention; in group 2, only psychiatrists receive intervention; and in group 3, patients/relatives and psychiatrists receive intervention. The primary outcome is adherence to the antidepressant drug. The calculated sample size is 400 patients. To examine changes across time, generalized linear mixed model with repeated measures will be used. A cost-effectiveness analysis will be conducted. The effectiveness measure is quality-adjusted life years. Deterministic sensitivity analyses are planned. CONCLUSION: MAPDep study aims to assess a multicomponent strategy to improve adherence toward medications in patients with depression, based not only on clinical effectiveness but also on cost-effectiveness. This methodology will enhance the transferability of the expected results beyond mental health services (patients and psychiatrists) to health care policy decision making. CLINICAL TRIAL IDENTIFIER: NCT03668457.
RESUMO
BACKGROUND: Given the economic burden of seasonal influenza for the healthcare system, we performed a systematic review aiming to update available evidence on the cost-effectiveness of vaccination of seasonal influenza in different age groups, including children. METHODS: A systematic review of the literature on economic evaluations of seasonal influenza vaccination programs in children and adults was carried out. The following databases were searched (January 2013 - April 2018): Medline and PREMEDLINE, EMBASE, EconLit and databases of the Centre for Reviews and Dissemination (DARE, HTA, NHS EED). RESULTS: A total of 11 economic evaluations were included. Methodological quality of included studies was acceptable. Scientific evidence shows that seasonal influenza vaccination programs in school-age children can be a cost-effective alternative from national health system perspective and can be cost-saving from societal perspective in European countries. However, available evidence does not allow us to conclude that influenza vaccination programs in healthy adults under 65 years of age were a cost-effective alternative in our context, due to the high uncertainty and the lack of studies carried out in Spanish context. CONCLUSIONS: Vaccination programs for the prevention of seasonal influenza in school-age children (3-16 years) can be a cost-effective strategy.
OBJETIVO: Dada la carga económica que supone para el sistema sanitario la gripe estacional, se plantea esta revisión sistemática cuyo objetivo fue actualizar la evidencia disponible sobre el coste-efectividad de vacunación contra la gripe estacional en diferentes grupos de edad, incluyendo población infantil. METODOS: Se llevó a cabo una revisión sistemática de la literatura de evaluaciones económicas de los programas de vacunación contra la gripe estacional en niños y adultos. Se realizaron búsquedas en las bases de datos (enero 2013 abril 2018): Medline y PREMEDLINE, EMBASE, EconLit y en las bases de datos del Centre for Reviews and Dissemination (DARE, HTA, NHS EED). RESULTADOS: Se incluyeron 11 evaluaciones económicas. La calidad metodológica de los estudios incluidos fue buena. La evidencia científica muestra que los programas de vacunación contra la gripe estacional en niños en edad escolar pueden ser una estrategia coste-efectiva desde la perspectiva sanitaria en países europeos. La evidencia científica disponible hasta el momento no nos permite concluir que los programas de vacunación antigripal en adultos sanos de menos de 65 años de edad sean una alternativa costeefectiva en nuestro contexto, debido a la elevada incertidumbre existente y a la escasez de estudios realizados en el contexto español. CONCLUSIONES: Los programas de vacunación contra la gripe estacional en niños en edad escolar (3-16 años) pueden ser una estrategia coste-efectiva desde la perspectiva del SNS.

INTRODUCTION: Lung cancer is the third most frequent neoplastic tumour in Spain, with around 27 000 new cases diagnosed per year; 80-95% of these are non-small-cell cancer (NSCLC), and the majority of cases are diagnosed in advanced stages of the disease, and for this reason it is one of the oncologic conditions with higher mortality rates (21.4% mean survival at 5 years). The main treatment regimens used for first-line treatment of NSCLC are: cisplatin/pemetrexed (cis/pem), cisplatin/gemcitabine/ bevacizumab (cis/gem/bev), and carboplatin/paclitaxel/ bevacizumab (carb/pac/bev). The objective of this study was to evaluate the cost-effectiveness ratio of antineoplastic 1st line NSCLC treatment regimens, from the point of view of hospital management. METHODOLOGY: A cost-efficacy mathematical model was prepared, based on a decision tree. The efficacy variable was Progression Free Survival, obtained from the PARAMOUNT, AVAIL and SAIL Phase III clinical trials. The study was conducted from the perspective of the hospital management, considering only the direct costs of drug acquisition. A deterministic sensitivity analysis was conducted to confirm the robustness of outcomes. RESULTS: The PFS obtained in clinical trials with cis/pem, cis/ gem/bev and carb/pac/bev was: 6.9, 6.7 and 6.2 months, respectively. Based on our model, the mean cost of treatment per patient for these regimens was: 19 942 , 15 594 and 36 095 , respectively. The incremental cost-effectiveness ratio per month of additional PFS between cis/pem and cis/gem/bev was 19 303 . Estimating a 30% reduction in acquisition costs for pemetrexed (Alimta®Eli Lilly Nederland B.V.), due to the forthcoming launch of generic medications, the cis/pem treatment would become the predominant alternative for 1st line treatment of NSCLC patients, by offering the best health results at a lower cost.
Introducción: El cáncer de pulmón es la tercera neoplasia tumoral más frecuente en España, con unos 27.000 nuevos casos/ año, de los que el 80-85% son de etiología no microcítica (NSCLC) y en la mayoría de los casos diagnosticados en estadíos avanzados de la enfermedad, razón por la que es uno de los procesos oncológicos con mayores tasas de mortalidad (supervivencia media a los 5 años del 21,4%). Los principales esquemas de primera línea utilizados en el tratamiento del NSCLC son: cisplatino/pemetrexed (cis/pem), cisplatino/gemcitabina/ bevacizumab (cis/gem/bev), y carboplatino/paclitaxel/bevacizumab (carbo/pac/Bev). El objetivo del presente trabajo consistirá en realizar un análisis para estimar el ratio coste-eficacia de los esquemas antineoplásicos de primera línea en el tratamiento del NSCLC, desde la perspectiva de la gerencia hospitalaria. Metodos: Se elaboró un modelo matemático de coste-eficacia basado en un árbol de decisiones. Como variable de eficacia se utilizó la supervivencia libre de progresión, obtenida de los ensayos clínicos fase III PARAMOUNT, AVAIL y SAIL. El estudio se efectuó desde la perspectiva de la gerencia hospitalaria considerando únicamente los costes directos de adquisición de los fármacos. Se realizó un análisis de sensibilidad determinístico para comprobar la robustez de los resultados. Resultados: La SLP obtenida en los ensayos clínicos de los tratamientos cis/pem, cis/gem/bev y carb/pac/bev fue de: 6,9, 6,7 y 6,2 meses, respectivamente. En base a nuestro modelo, el coste medio del tratamiento por paciente para estos esquemas fue de 19.942 , 15.594 y 36.095 , respectivamente. La razón coste-eficacia incremenal por mes de SLP adicional entre cis/pem y cis/gem/bev fue de 19.303 . Estimando una reducción del 30% de los costes de adquisición de pemetrexed (Alimta®Eli Lilly Nederland B.V) ante su próxima incorporación al mercado de medicamentos genéricos, el tratamiento cis/pem se convertiría en la alternativa dominante en el tratamiento de primera línea de los pacientes con NSCLC, al ofrecer los mejores resultados en salud a un menor coste.

There is a growing concern and awareness of skin cancer. As a result, possibly unnecessary surgeries of melanocytic lesions are carried out as a prophylactic measure. We performed a systematic review of the medical literature to identify primary studies on the effectiveness and cost-effectiveness of surgery treatment of benign melanocytic lesions for melanoma prevention. We included 19 primary studies on surgical treatment of acquired melanocytic lesions and one economic evaluation. Indicators, such as number needed to treat and the malignancy ratio, depend on several factors such as specialty and experience of the physician, pressure from the patient or patient characteristics. Early diagnosis of melanoma is critical in preventing skin cancer. However, primary studies show through several indicators that there are factors that increase the proportion of lesions treated unnecessarily. Effectiveness can be improved by careful use of techniques to identify suspicious lesions and educational programs for physicians, especially in primary care.

To incorporate economic evaluation into decision-making, we need to know how much a health system is willing and able to invest in a quality-adjusted life year (QALY). In Spain, the figure of 30,000 per QALY as cost-effectiveness (CE) threshold has been widely cited. However, as in most health systems, no value has been formally adopted; mainly because of the arbitrariness, the lack of theoretical and scientific basis, and the controversy around its estimation and what the threshold should represent. Based on a systematic review of empirical studies on the estimation of the CE threshold undertaken by this research team, we conducted a critical appraisal of the state of the art, using a Delphi with the participation of 13 national experts. This paper contributes to assess the research progress on the CE threshold in Spain, to consider its utility in the decision making process supported by economic evaluation, and to propose further research to improve what has been achieved so far.

BACKGROUND: The use of cerebrospinal fluid (CSF) biomarkers could facilitate early detection of Alzheimer's disease (AD) in patients with mild cognitive impairment (MCI) and the differential diagnosis between AD and non-AD dementias. OBJECTIVE: To determine the cost-effectiveness of the use of amyloid-ß peptide (Aß42), total tau and phosphorylated tau proteins in CSF to diagnose AD in MCI and dementia patients. METHODS: An economic evaluation was performed by means of cost-effectiveness analysis comparing two AD diagnostic alternatives: the combined determination of Aß42 proteins, total tau and phosphorylated tau in CSF as biomarkers of AD, and the standard clinical diagnosis based on the National Institute of Neurological and Communicative Disorders and Stroke and the Alzheimer's Disease and Related Disorders Association (NINDS-ADRDA) criteria. A decision analytic model was developed to synthesize the identified evidence and to compare the costs and effectiveness associated with each diagnostic strategy. A probabilistic sensitivity analysis using 2nd order Monte Carlo simulations was performed. Subsequently, acceptability curves were calculated and ANCOVA models were applied to the results of the Monte Carlo simulations in order to identify the parameters that led greater variability in the model outcomes. RESULTS: The use of CSF biomarkers as an early diagnostic strategy of AD in MCI patients is a dominant alternative (less costly and more effective strategy than standard clinical diagnostic criteria). In dementia patients, although there is a higher uncertainty, biomarkers in CSF seem a more cost-effective alternative than standard clinical diagnostic criteria. CONCLUSIONS: Detecting AD in MCI patients by determining Aß42, total tau and phosphorylated tau proteins biomarkers in CSF is a cost-effective diagnostic alternative. No conclusive results were obtained on dementia patients.

BACKGROUND: To assess the cost-utility of gastric bypass versus usual care for patients with severe obesity in Spain. METHODS: We have implemented a discrete-event simulation model with two branches: one branch involves gastric bypass, thereby reducing patients' BMI, and another branch where patients do not undergo surgery. The model analyzes the emergence of comorbidities (stroke, coronary obstructive disease, diabetes, and breast cancer) associated with obesity during a lifetime horizon. The selected measure of effectiveness is health-related quality of life. Both costs and effects are discounted at 3 %. A probabilistic sensitivity analysis is also performed using second-order Monte Carlo simulation; acceptability curves for different time horizons were also calculated. RESULTS: Patients with gastric bypass result in a lifetime increase of 5.63 quality-adjusted life years (QALYs) (18.18 vs. 12.55 QALYs). In addition, because of the reduced spending associated with the treatment of various obesity-related comorbidities, final savings stand at 13,994
