RESUMO
BACKGROUND: The extensive and continuous reuse of sensitive health data could enhance the role of population health research on public decisions. This paper describes the design principles and the different building blocks that have supported the implementation and deployment of Population Health Information Research Infrastructure (PHIRI), the strengths and challenges of the approach and some future developments. METHODS: The design and implementation of PHIRI have been developed upon: (i) the data visiting principle-data does not move but code moves; (ii) the orchestration of the research question throughout a workflow that ensured legal, organizational, semantic and technological interoperability and (iii) a 'master-worker' federated computational architecture that supported the development of four uses cases. RESULTS: Nine participants nodes and 28 Euro-Peristat members completed the deployment of the infrastructure according to the expected outputs. As a consequence, each use case produced and published their own common data model, the analytical pipeline and the corresponding research outputs. All the digital objects were developed and published according to Open Science and FAIR principles. CONCLUSION: PHIRI has successfully supported the development of four use cases in a federated manner, overcoming limitations for the reuse of sensitive health data and providing a methodology to achieve interoperability in multiple research nodes.

BACKGROUND: Resilience of national health systems in Europe remains a major concern in times of multiple crises and as more evidence is emerging relating to the indirect effects of the COVID-19 pandemic on health care utilization (HCU), resulting from de-prioritization of regular, non-pandemic healthcare services. Most extant studies focus on regional, disease specific or early pandemic HCU creating difficulties in comparing across multiple countries. We provide a comparatively broad definition of HCU across multiple countries, with potential to expand across regions and timeframes. METHODS: Using a cross-country federated research infrastructure (FRI), we examined HCU for acute cardiovascular events, elective surgeries and serious trauma. Aggregated data were used in forecast modelling to identify changes from predicted European age-standardized counts via fitted regressions (2017-19), compared against post-pandemic data. RESULTS: We found that elective surgeries were most affected, universally falling below predicted levels in 2020. For cardiovascular HCU, we found lower-than-expected cases in every region for heart attacks and displayed large sex differences. Serious trauma was the least impacted by the COVID-19 pandemic. CONCLUSION: The strength of this study comes from the use of the European Population Health Information Research Infrastructure's (PHIRI) FRI, allowing for rapid analysis of regional differences to assess indirect impacts of events such as pandemics. There are marked differences in the capacity of services to return to normal in terms of elective surgery; additionally, we found considerable differences between men and women which requires further research on potential sex or gender patterns of HCU during crises.

BACKGROUND: The indirect impact of the coronavirus disease 2019 pandemic on healthcare services was studied by assessing changes in the trend of the time to first treatment for women 18 or older who were diagnosed and treated for breast cancer between 2017 and 2021. METHODS: An observational retrospective longitudinal study based on aggregated data from four European Union (EU) countries/regions investigating the time it took to receive breast cancer treatment. We compiled outputs from a federated analysis to detect structural breakpoints, confirming the empirical breakpoints by differences between the trends observed and forecasted after March 2020. Finally, we built several segmented regressions to explore the association of contextual factors with the observed changes in treatment delays. RESULTS: We observed empirical structural breakpoints on the monthly median time to surgery trend in Aragon (ranging from 9.20 to 17.38 days), Marche (from 37.17 to 42.04 days) and Wales (from 28.67 to 35.08 days). On the contrary, no empirical structural breakpoints were observed in Belgium (ranging from 21.25 to 23.95 days) after the pandemic's beginning. Furthermore, we confirmed statistically significant differences between the observed trend and the forecasts for Aragon and Wales. Finally, we found the interaction between the region and the pandemic's start (before/after March 2020) significantly associated with the trend of delayed breast cancer treatment at the population level. CONCLUSIONS: Although they were not clinically relevant, only Aragon and Wales showed significant differences with expected delays after March 2020. However, experiences differed between countries/regions, pointing to structural factors other than the pandemic.

Government employees in Spain are covered by public Mutual Funds that purchase a uniform basket of benefits, equal to the ones served to the general population, from private companies. Companies apply as private bidders for a fixed per capita premium hardly adjusted by age. Our hypothesis is that this premium does not cover risks, and companies have incentives for risk selection, which are more visible in high-cost patients. We focus on a particularly costly disease, cancer, whose prevalence is similar among government employees and the general population. We compare hospitalisations in the public hospitals of the government employees that have chosen public provision and the general population. We analysed a database of hospital discharges in the Valencian Community from 2010 to 2015 (3 million episodes). Using exact matching and logistic models, we find significant risk selection; thus, in hospitalised government employees, the likelihood for a solid metastatic carcinoma and non-metastatic cancer to appear in the registry is 31% higher than in the general population. Lymphoma shows the highest odds ratio of 2.64. We found quantitatively important effects. This research provides indirect evidence of risk selection within Spanish Mutual Funds for government employees, prompting action to reduce incentives for such a practice. More research is needed to figure out if what we have observed with cancer patients occurs in other conditions.
RESUMO
INTRODUCTION: The sustainability of public hospital financing in Spain is a recurring issue, given its representativeness in annual public healthcare budgets which must adapt to the macroeconomic challenges that influence the evolution of spending. Knowing whether the responsiveness of hospital expenditure to its determinants (need, utilisation, and quasi-prices) varies according to the type of hospital could help better design strategies aimed at optimising performance. METHODS: Using SARIMAX models, we dynamically assess unique nationwide monthly activity data over a 14-year period from 274 acute-care hospitals in the Spanish National Health Service network, clustering these providers according to the average severity of the episodes treated. RESULTS: All groups showed seasonal patterns and increasing trends in the evolution of expenditure. The fourth quartile of hospitals, treating the most severe episodes and accounting for more than 50% of expenditure, is the most sensitive to quasi-price factors, particularly the number of beds per hospital. Meanwhile, the first quartile of hospitals, which treat the least severe episodes and account for 10% of expenditure, is most sensitive to quantity factors, for which expenditure showed an elasticity above one, while factors of production were not affected. CONCLUSIONS: Belonging to one or another cluster of hospitals means that the determinants of expenditure have a different impact and intensity. The system should focus on these differences in order to optimally modulate expenditure not only according to the needs of the population, but also according to the macroeconomic situation, while leaving hospitals room for manoeuvre in case of unforeseen events. The findings suggest strengthening a network of smaller hospitals (Group 1)-closer to their reference population, focused on managing and responding to chronicity and stabilising acute events-prior to transfer to tertiary hospitals (Group 4)-larger but appropriately sized, specialising in solving acute and complex health problems-when needed.

OBJECTIVES: Long-term breast cancer survivors (BCS) constitute a complex group of patients, whose number is estimated to continue rising, such that, a dedicated long-term clinical follow-up is necessary. MATERIALS AND METHODS: A dynamic time warping-based unsupervised clustering methodology is presented in this article for the identification of temporal patterns in the care trajectories of 6214 female BCS of a large longitudinal retrospective cohort of Spain. The extracted care-transition patterns are graphically represented using directed network diagrams with aggregated patient and time information. A control group consisting of 12 412 females without breast cancer is also used for comparison. RESULTS: The use of radiology and hospital admission are explored as patterns of special interest. In the generated networks, a more intense and complex use of certain healthcare services (eg, radiology, outpatient care, hospital admission) is shown and quantified for the BCS. Higher mortality rates and numbers of comorbidities are observed in various transitions and compared with non-breast cancer. It is also demonstrated how a wealth of patient and time information can be revealed from individual service transitions. DISCUSSION: The presented methodology permits the identification and descriptive visualization of temporal patterns of the usage of healthcare services by the BCS, that otherwise would remain hidden in the trajectories. CONCLUSION: The results could provide the basis for better understanding the BCS' circulation through the health system, with a view to more efficiently predicting their forthcoming needs and thus designing more effective personalized survivorship care plans.

Since the early 2000's, the Atlas of Variations in Medical Practice in the Spanish National Health System (namely, Atlas VPM) has been analysing and informing unwarranted variations in health care provision and outcomes in the Spanish Health System.Atlas VPM covers a two-fold perspective: a geographic one, where unwarranted variations would reflect the uneven exposure of the population to health care as a consequence of the place of residence; and, a provider-specific approach, where unwarranted variations would reflect differences in utilisation and outcomes that are at provider-level.Building on routine data (hospital and primary care electronic records, administrative data, geographic information, etc.) Atlas VPM has adapted the classical small area methods and has included a large panoply of techniques, such as Bayesian methods, hierarchical modelling or time-series forecasting.Led by the Data Science for Health Services and Policy Research group at the Institute for Health Sciences in Aragon, Atlas VPM implies a linkage and exchange process with the 17 Departments of Health of the Spanish regions where the research agenda is shared and research outcomes are translated into profiling and benchmarking interactive tools meant to facilitate clinical and policy decision-making.
RESUMO
This analysis of the Spanish health system reviews recent developments in organization and governance, health financing, health care provision, health reforms and health system performance. Overall health status continues to improve in Spain, and life expectancy is the highest in the European Union. Inequalities in self-reported health have also declined in the last decade, although long-standing disability and chronic conditions are increasing due to an ageing population. The macroeconomic context in the last decade in the country has been characterized by the global economic recession, which resulted in the implementation of health system-specific measures addressed to maintain the sustainability of the system. New legislation was issued to regulate coverage conditions, the benefits package and the participation of patients in the National Health System funding. Despite the budget constraints linked to the economic downturn, the health system remains almost universal, covering 99.1% of the population. Public expenditure in health prevails, with public sources accounting for over 71.1% of total health financing. General taxes are the main source of public funds, with regions (known as Autonomous Communities) managing most of those public health resources. Private spending, mainly related toout-of-pocket payments, has increased over time, and it is now above the EU average. Health care provision continues to be characterized by the strength of primary care, which is the core element of the health system; however, the increasing financing gap as compared with secondary care may challenge primary care in the long term. Public health efforts over the last decade have focused on increasing health system coordination and providing guidance on addressing chronic conditions and life style factors such as obesity. The underlying principles and goals of the national health system continue to focus on universality, free access, equity and fairness of financing. The evolution of performance measures over the last decade shows the resilience of the health system in the aftermath of the economic crisis, although some structural reforms may be required to improve chronic care management and the reallocation of resources to high-value interventions.

The Health Systems in Transition (HiT) country profiles provide an analytical description of each health system and of policy initiatives in progress or under development. They aim to provide relevant comparative information to support policy-makers and analysts in the development of health systems and reforms in the countries of the WHO European Region and beyond. The HiT profiles are building blocks that can be used: to learn in detail about different approaches to the financing, organization and delivery of health services; to describe accurately the process, content and implementation of health reform programmes; to highlight common challenges and areas that require more in-depth analysis; and to provide a tool for the dissemination of information on health systems and the exchange of experiences of reform strategies between policy-makers and analysts in countries of the WHO European Region. This series is an ongoing initiative and material is updated at regular intervals.

Este estudio forma parte de una serie de informes nacionales que han generado nueva evidencia sobre la protección financiera en los sistemas sanitarios europeos. La protección financiera es fundamental para la cobertura sanitaria universal y es una dimensión básica del desempeño de los sistemas sanitarios. A pesar de haber empeorado durante la crisis económica entre los años 2008 y 2014, la incidencia de los gastos catastróficos en salud en España es mucho menor de lo que cabría esperar dada la dependencia relativamente elevada de los pagos directos en España. Esto puede explicarse por los puntos fuertes de las políticas decobertura en el Sistema Nacional de Salud (SNS): cobertura sanitaria basada en la residencia, con la misma cobertura para los inmigrantes en situación no regularizada; una cartera de servicios completa en general; uso limitado de los copagos, y diferentes mecanismos para proteger a los usuarios de los copagos. Sin embargo, la cobertura presenta algunas deficiencias. Las causas principales del gasto catastrófico son la atención dental y los productos sanitarios en todos los quintiles de consumo, principalmente porque la atención dental y óptica están excluidas en gran medida de la cobertura del SNS. En el quintil más pobre, la causa del gasto catastrófico son los medicamentos de dispensación ambulatoria debidoa los copagos y a una protección inadecuada de los hogares de bajos ingresos con personas en edad de trabajar. Para reducir las necesidades insatisfechas y las dificultades financieras, las políticas deben centrarse en ampliar la cobertura del SNS para la atención dental y la atención óptica, así como seguir mejorando las modalidades de copago para reforzar la protección de los hogares más pobres en todos los grupos de edad.

This review is part of a series of country-based studies generating new evidence on financial protection in European health systems. Financial protection is central to universal health coverage and a core dimensionof health system performance. Despite worsening during the economic crisis from 2008 to 2014, the incidence of catastrophic health spending in Spain is much lower than would be expected given Spain’s relatively heavy reliance on out-of-pocket payments. This can be explained by strengths in the design of coverage policy in the National Health System (NHS): entitlement to the NHS based on residence, with the same degree of entitlement for undocumented migrants; a generally comprehensive benefits package; limited use of co-payments; and multiple mechanisms to protect people from co-payments. There are gaps in coverage, however. Catastrophic spending is driven by dental care and medical products in all consumption quintiles, mainly because dental and optical care for eyesight problems are largely excluded from NHS coverage. Catastrophic spending in the poorest quintile is also driven by outpatient medicines, reflecting co-payments and inadequate protection for low-incomehouseholds of working age. To reduce unmet need and financial hardship, policy should focus on expanding NHS coverage of dental care and optical care and further improving the design of co-payments to strengthenprotection for poorer households in all age groups.
