In the field of the economic evaluation (EE), there is an open debate on the most appropriate perspective to apply. Despite the relevance of the topic, there are hardly any studies that have analyzed the practical consequences of applying the social perspective vs. health care funder. The aim of this study was performed a systematic review of the available evidence to analyze whether the inclusion/exclusion of informal care and/or loss of productivity influence the results and conclusions of economic evaluations.A systematic review of the literature was carried out using PubMed and Econlit databases, to determine the publications that contained EE on Alzheimer, Parkinson and Stroke. Inclusion criteria were: a) full EE of the diseases under study; b) from January 2006-July 2016; and c) in English or Spanish.6,292 references were identified, of which 245 publications meet the selection criteria and were analyzed. After the full-text analysis, 20 references were selected, of which 27 full EE were obtained (20 corresponding to Alzheimer, 1 to Parkinson and 6 to Stroke). In 20 EE (74.1%) the change of the perspective modifies the results, becoming dominant or increasing the saving of the resources by comparing the alternatives from the social perspective. In the remaining 7, the inclusion of social costs involves an increase in the costs of the intervention evaluated against its control. In a single EE, the conclusions vary when including social costs.The inclusion of social costs can modify the results of EE but their impact on the conclusions is not relevant.En el campo de la evaluación económica (EE), existe un debate abierto sobre la perspectiva más apropiada a aplicar. Pese a la relevancia del tema, apenas hay trabajos que analicen las consecuencias prácticas de aplicar la perspectiva social o la del financiador. El objetivo fue realizar una revisión sistemática para analizar si la inclusión/exclusión de los cuidados informales y/o pérdidas laborales influyen en los resultados y conclusiones de las EE.Se realizó una búsqueda sistemática en PubMed y Econlit para determinar las publicaciones que contenían EE sobre Alzheimer, Parkinson e Ictus. Criterios de inclusión: a) EE completas sobre las enfermedades en estudio; b) periodo enero 2006-julio 2016; y c) en inglés o español.Se obtuvieron 6.292 referencias, seleccionándose 245 artículos que podían cumplir los criterios de inclusión. Tras el análisis a texto completo, se seleccionaron 20 publicaciones de las cuales se obtuvieron 27 EE completas (20 corresponden a Alzheimer, 1 a Parkinson y 6 al Ictus). En 20 EE (74,1%) el cambio de perspectiva modifica los resultados, pasando a ser dominantes o incrementando el ahorro de recursos comparando las alternativas desde la perspectiva social. En las 7 restantes, la inclusión de los costes sociales supone un incremento en los costes de la intervención evaluada frente a su control. Únicamente en una EE varían las conclusiones al incluir los costes sociales.En general, la inclusión de los costes sociales puede modificar los resultados de las EE, pero su impacto sobre las conclusiones de las mismas es poco relevante.

Fundamentos: El impacto económico que causan las enfermedades va mucho más allá del gasto sanitario, transmitiéndose a la sociedad a través de diferentes dimensiones. El principal objetivo de este estudio fue estimar la evolución de las pérdidas de productividad laboral causadas por muertes prematuras en España durante el periodo 2005-2009. Métodos: Se emplearon varias fuentes estadísticas (Registro de defunciones según la causa de muerte, Encuesta de Población Activa y Encuesta de Estructura Salarial) para desarrollar un modelo de simulación basado en el enfoque de capital humano que permitió estimar las pérdidas laborales ocasionadas por muertes prematuras para el periodo analizado. Adicionalmente, se llevaron a cabo dos escenarios alternativos en los que se analizó la influencia de la evolución epidemiológica en los resultados obtenidos. Resultados: El modelo de simulación mostró una caída de las pérdidas laborales asociadas a muertes prematuras que fue desde 8.935 millones de euros en 2005 a 8.073 millones de euros en 2009. El análisis de las causas reducidas de muerte señaló que nueve causas de enfermedad (accidentes de tráfico, tumor maligno de tráquea, suicidios, infarto agudo de miocardio, SIDA, cirrosis, tumor de mama, enfermedades cerebrovasculares y cáncer de colon) supusieron el 35,6% del total de Años Potenciales de Vida Laboral Perdidos y 36,6% del total de pérdida estimada. Las pérdidas estimadas representaron el 0,98%, 0,85% y 0,77% del Producto Interior Bruto de 2005, 2007 y 2009, respectivamente. Conclusiones: Las pérdidas laborales ocasionadas por muertes prematuras en España disminuyeron sustancialmente en el periodo analizado. Esta reducción se debió fundamentalmente a la favorable evolución epidemiológica de la mortalidad prematura. Background: The economic impact caused by diseases goes far beyond health care costs and, therefore it is transferred to the society through different dimensions. The aim of this study was to estimate the productivity losses due to premature deaths caused by diseases occurred in Spain during the period 2005-2009. Methods: We used data from several sources (Death Registry, Labour Force Survey and Wage Structure Survey) to develop a simulation model based on the human-capital approach that allowed us to estimate the labour productivity losses caused by premature deaths in the period analysed. Additionally, we also carried out two alternative scenarios in which we analysed how epidemiologic data influenced our results. Results: Our model showed the estimated loss of productivity due to premature death fell from 8,935 billion euros in 2005 to 8,073 billion euros in 2009. Nine diseases (traffic accidents, malignant tumour of the trachea, suicides, acute myocardial infarction, AIDS, cirrhosis, breast tumour, cerebrovascular disease and colon cancer) accounted for 35.6% of the total Years of Potential Productive Life Lost and 36.5% of the estimated productivity losses. The estimated losses represented 0.98%, 0.85% and 0.77% of Gross Domestic Product in 2005, 2007 and 2009, respectively. Conclusions: The labour productivity losses caused by premature deaths decreased substantially in the period analysed. This reduction was mainly due to the epidemiological evolution of premature mortality.

The development of the economic evaluation of health care interventions has become a support tool in making decisions on pricing and reimbursement of new health interventions. The increasingly extensive application of these techniques has led to the identification of particular situations in which, for various reasons, it may be reasonable to take into account special considerations when applying the general principles of economic evaluation. In this article, which closes a series of three, we will discuss, using the Metaplan technique, about the economic evaluation of health interventions in special situations such as rare diseases and end of life treatments, as well as consideration of externalities in assessments, finally pointing out some research areas to solve the main problems identified in these fields.

In this second article of a series of three, we will discuss using the Metaplan technique on controversial issues of health outcomes in economic evaluation of health care interventions. The four-discussion areas focus on: choice of health outcomes measures, where any outcome measure is superior to another; extrapolation and transferability of health outcomes measures, which should not be assumed the results of an EEIS of one country to another without making certain adjustments; appropriate instruments to measure quality of life in Spain, where the EQ-5D was indicated as convenient due to its widespread international use; and, indirect comparisons, where the combination of both comparisons, direct and indirect, it would be advisable if the test for indirect estimates is consistent and has been validated. Finally, research lines to try to overcome the identified discrepancies were identified in each of these areas, some of those are: doing studies of correlation between scores of specific and generic instruments measuring quality of life; update or create a database of economic evaluations in Spain; estimating utilities for the Spanish population by existing generic and specific instruments; or, establish a common way to show the results of a meta-analysis network.

Economic evaluation of health care interventions has experienced a strong growth over the past decade and is increasingly present as a support tool in the decisions making process on public funding of health services and pricing in European countries. A necessary element using them is that agents that perform economic evaluations have minimum rules with agreement on methodological aspects. Although there are methodological issues in which there is a high degree of consensus, there are others in which there is no such degree of agreement being closest to the normative field or have experienced significant methodological advances in recent years. In this first article of a series of three, we will discuss on the perspective of analysis and assessment of costs in economic evaluation of health interventions using the technique Metaplan. Finally, research lines are proposed to overcome the identified discrepancies.

Jointly with deaths, loss of quality of life and pain of patients and families, there are complementary indicators that help to reveal the social impact caused by illnesses and accidents. In the analysis, loss of labour productivity due to premature mortality in 2005 is estimated. The aim of this work is to estimate a part of the non health care costs caused by illnesses and accidents in the economy.A simulation model based in the human capital approach is developed using several available Spanish data bases (Death Registry According to Cause of Death, Structural Wage Survey, Labour Force Survey).A loss of production up to 9,100 millions of Euros due to premature mortality is estimated in Spain for the base year. This figure is equivalent to a 1.01% of the Spanish Gross Domestic Product, or to an 18.25% of the Public Health Care Expenditure of 2005.Premature mortality caused a very high labour cost.
