The Portuguese health system concentrates most of its activity in a National Health Service, created in 1979 to promote universal and general access. The National Health Service should ensure equity, efficiency, and quality of all health care delivered services. This study assesses the impact of health care policies between 2002 and 2017, focusing on 3 timeframes: the adoption and adaptation of New Public Management principles to the health care sector (2002 to 2010), the economic and financial crisis period (2011-2015), and the postcrisis recovery period (2016-2017). The current study evaluates the main policy measures in the health sector, presenting their impacts in terms of access, efficiency, accountability, and costs over those 3 economic periods. It was verified that not all the measures implemented by the successive governments obtained the desired outcomes, generating even costs increase, apart from the austerity period in which health expenditure showed a significant reduction because of the financial constraints.

Background Excessive consumption of sugar has a well-established link with obesity. Preliminary results show that a tax levied on sugar-sweetened beverages (SSBs) by the Portuguese government in 2017 led to a drop in sales and reformulation of these products. This study models the impact the market changes triggered by the tax levied on SSBs had on obesity incidence across various age groups in Portugal. Methods and findings We performed a national market analysis and population-wide modelling study using market data for the years 2014-2018 from the Portuguese Association of Non-Alcoholic Drinks (GlobalData and Nielsen Consumer Panel), dietary data from a national survey (IAN-AF 2015-2016), and obesity incidence data from several cohort studies. Dietary energy density from SSBs was calculated by dividing the energy content (kcal/gram) of all SSBs by the total food consumption (in grams). We used the potential impact fraction (PIF) equation to model

SummaryPortugal has one of the most complete public systems worldwide. Since 1979, the Portuguese National Health Service (NHS) was developed based on the integration and complementarity between different levels of care (primary, secondary, continued, and palliative care). However, in 2009, the absence of economic growth and the increased foreign debt led the country to a severe economic slowdown, reducing the public funding and weakening the decentralized model of health care administration. During the austerity period, political attention has focused primarily on reducing health care costs and consolidating the efficiency and sustainability with no structural reform. After the postcrisis period (since 2016), the recovery of the public health system begun. Since then, some proposals have required a reform of the health sector's governance structure based on the promotion of access, quality, and efficiency. This study presents several key issues involved in the current postcrisis reform of the Portuguese NHS response structure to citizens' needs. The article also discusses the implications of this Portuguese experience based on current reforms with impact on the future of citizens' health.
