Measuring the burden of disease and injury in Spain using disability-adjusted life years: an updated and policy-oriented overview.

OBJECTIVE: To provide a comprehensive and detailed overview of the burden of disease in Spain for 2008. Implications for public health policies are discussed. STUDY DESIGN: Cross-sectional population-based study. METHODS: Disability-adjusted life years (DALYs) were calculated at country level using the methodology developed in the Global Burden of Disease study. DALYs were divided into years of life lost and years of life lived with disability. Results were obtained using Spanish mortality data for 2008 and morbidity data estimated previously by the World Health Organization for Euro-A. RESULTS: In 2008, DALYs lost due to all diseases and injuries were estimated at 5.1 million. Non-communicable diseases accounted for 89.2% of the total DALYs. The leading causes of DALYs were neurological and mental disorders (29.9%), malignant neoplasms (15.8%) and cardiovascular diseases (12.5%). The main specific causes included depression (5.5%), ischaemic heart disease (5.5%), lung cancer (5.3%) and alcohol abuse (4.7%) among males; and depression (11.7%), dementias (10.0%), hearing loss (4.2%) and cerebrovascular disease (3.5%) among females. CONCLUSIONS: Measuring DALYs specifically for Spain represents a systematic analysis of population health losses, and also provides an important measure to track the outcomes of future health interventions.

Economic evaluation of interventions for malignant neoplasms in Spain: systematic review and comparative analysis.

OBJECTIVE: To review standard methods used to evaluate the efficiency of oncology interventions, comparing their main characteristics with those of the studies aimed for other conditions. METHODS: We performed a systematic review and comparative analysis calculating odds ratios (OR). We searched the biomedical literature to assess economic evaluation studies on malignant neoplasms in Spain published between 1983 and 2008. Their characteristics were reviewed and summarised, including the following variables: journal and year of publication, intervention, type and design of study, perspective, type of costs, financing source, and decision-making recommendations. RESULTS: Sixty-three studies were included. Main characteristics of the reports were: cost-effectiveness analysis and therapeutic interventions (60.3%; n=38). Seventeen studies (27.0%) used an observational design. Economic evaluations of malignant neoplasms showed the following associations (compared to those studies addressing other causes [n=411]): cost minimisation analysis (OR: 1.73; 95% confidence interval [CI]: 0.91-3.27), diagnostic interventions (OR: 2.18; 95% CI: 1.07-4.43), decision analysis design (OR: 0.46; 95% CI: 0.24-0.87), societal perspective (OR: 0.20; 95% CI: 0.05-0.86) and for-profit source of financing (OR: 0.52; 95% CI: 0.30-0.93). CONCLUSIONS: Economic evaluations of interventions for malignant neoplasms are not common despite the gradual increase produced during recent years in Spain. Reports presented heterogeneity in the quality of the information regarding the methods and the data sources used. Further efficiency evaluations of oncology interventions are needed and methodological quality should be warranted.

[Economic evaluation of interventions for infectious diseases in Spain: systematic review and comparative analysis]. / Evaluación económica de intervenciones en enfermedades infecciosas en España: revisión sistemática y análisis comparativo.

BACKGROUND: There exists the need to evaluate interventions addressed to prevent, control and reduce the burden of the infectious diseases; being economic evaluation an instrument can help to allocate healthcare resources efficiently. In this context, we assessed the evolution of economic evaluation of interventions for infectious diseases published in Spain, as well as we compared their main methodological characteristics with those of the studies directed to other diseases. METHODS: Systematic review and comparative analysis calculating odds ratios (OR). Electronic searches for literature beetwen 1983 and 2008 were conducted in PubMed/MEDLINE, SCOPUS, ISI Web of Knowledge, CRD, IME e IBECS, and manually in specialized journals and technical reports. The following variables were identified to analyze the characteristics of the reports: journal and year of publication, intervention, type of study, design, perspective, type of costs, financing source, and decision-making recommendations. RESULTS: One-hundred and one studies were included in the review. The main characteristics of the reports were: cost-effectiveness analysis (n=56; 55.4%), treatments evaluations (n=60; 59.4%) and the use of decision analysis and mathematical simulation models (n=63; 62.4%). Economic evaluation studies of infectious diseases showed the following associations (compared to a cohort of studies of other disease conditions [n=376]): cost-benefit analysis (OR, 3.55; 95% confidence interval [CI], 1.63 to 7.74), prevention (OR, 4.14; 95% CI, 2.49 to 6.90), and societal perspective (OR, 2.55; 95% CI, 1.43 to 4.56). CONCLUSION: Although there is an increase in the number of economic evaluations of infectious diseases published during last decades, the studies showed heterogeneity in the quality of the information regarding methods of analysis and data sources.

[Economic evaluation of neurological and mental disorders in Spain: systematic review and comparative analysis]. / Evaluacion economica sobre enfermedades neurologicas y mentales en Espana: revision sistematica y analisis comparativo.

AIM: We analyzed the trends over time and the characteristics of economic evaluation studies of neurological and mental disorders published in Spain between 1983 and 2008. MATERIALS AND METHODS: Systematic review and comparative analysis calculating odds ratios (OR). Electronic searches for literature were conducted in PubMed/Medline, Scopus, ISI Web of Knowledge, CRD, IME and IBECS, and manually in specialized journals and technical reports. RESULTS: The 52 studies included in the review showed heterogeneity in the quality of the information regarding methods of analysis and data sources. Economic evaluation studies of neurological and mental disorders showed the following associations, compared to a cohort of studies of other disease conditions (n = 425): cost-utility analysis (OR = 1.57; 95% confidence interval, 95% CI = 0.77-3.22), treatments (OR = 3.02; 95% CI = 1.33-6.88), simulation mathematics models (OR = 2.51; 95% CI = 1.30-4.87), and healthcare system perspective (OR = 1.43; 95% CI = 0.80-2.54). CONCLUSIONS: Findings suggested that there is little research on economic evaluation research on neurological and mental disorders in Spain. In the future, more and better quality economic evaluation studies -according to their burden generated- are expected.
