Direct economic burden of acute coronary syndromes in the Portuguese National Health Service—facts and trends between 2002 and 2022
Aim: We estimated the average direct cost per Acute Coronary Syndromes (ACS) in-patient episodes by diagnosis, namely ST-elevation myocardial infarction (STEMI), non-ST elevation myocardial infarction (NSTEMI), unstable angina (UA), and undetermined AMI (Acute Myocardial Infarction). We also analyzed the changes in direct costs over time between 2002 and 2022, and the total direct economic burden of ACS hospitalizations for the Portuguese Nationa…
Are Policies Implemented Where Most Needed? Exploring Equity in School‐Based Smoking Prevention in 2013 and 2016 in Six European Cities
BACKGROUND: Health policies are key social determinants of health, but may cause inequalities if their implementation does not match local needs and if resources are misallocated. This study tests the inverse prevention law on school tobacco policies, assessing inequity in their implementation and identifying contributing factors. METHODS: A student survey and a staff survey were conducted in 38 schools across six European cities in 2013 and 2016…
Understanding the health system drivers of delayed cancer diagnosis in public healthcare networks of Chile, Colombia and Ecuador: A qualitative study with health professionals, managers and policymake…
Although the greatest delays in cancer diagnosis in Latin America occur in the provider interval little is known about the related factors. This study aims to analyze factors influencing access to cancer diagnosis -from initial contact with health services to confirmation- from institutional stakeholders' perspective in public healthcare networks of Chile, Colombia, and Ecuador. A qualitative, descriptive-interpretative study was conducted in two…
Freedom of choice for specialized consultation in Portugal: An observational analysis of response to hospital quality
The emergence of socioeconomic inequalities in smoking during adolescence and early adulthood
These results highlight that actions to prevent smoking should also take in account the potential impact in smoking inequalities, and should focus not only on middle adolescence but also on late adolescence and early adulthood
Change in the Prevalence and Social Patterning of First- and Second-Hand Smoking in Portugal: A Repeated Cross-Sectional Study (2005 and 2014)
Between 2005 and 2007, important reinforcements of the tobacco legislation have been implemented in Portugal, which may have affected smoking patterns. The aim of this study was to measure the change in prevalence of first- and second-hand smoking (SHS) among adults, and its socio-demographic patterning in Portugal from 2005 to 2014. Data from the last two Portuguese National Health Interview Surveys (2005 and 2014) were used. The changes in dail…
Academic Well-Being and Structural Characteristics of Peer Networks in School
Peer networks at school and students' position in these networks can influence their academic well-being. We study here individual students' network position (isolation, popularity, social activity) and peer network structures at the school level (centralization, density, clustering, school connectedness) and their relations to students' academic well-being (school burnout, SB; schoolwork engagement, SE). Classroom surveys for 14-16-year-olds ( N…
Effect of a national primary care reform on avoidable hospital admissions (2000-2015): A difference-in-difference analysis

Is food insecurity related to health-care use, access and absenteeism
Objective: Food insecurity (FI) is defined as uncertain access to healthy food in quantity and quality. We hypothesize that FI may be associated with greater health-care use and absenteeism because it may amplify the effect of diseases; also, FI may be associated with reduced health-care access because it reflects economic vulnerability. The present study estimates the association between FI and health-care use and access, and absenteeism. Design…
Dietary changes during the Great Recession in Portugal: Comparing the 2005/2006 and the 2014 health surveys
Objective We aimed at analysing changes in consumption of selected food groups in the Portuguese population before and after the Great Recession, which hit the country between 2008 and 2013. Design We used pooled cross-sectional data from the Portuguese National Health Interview Surveys of 2005/2006 and 2014. We modelled the probability of consumption of soup, fish, meat, potatoes/rice/pasta, bread, legumes, fruit, vegetables and sweets/desserts,…
Inequalities in adolescent self-rated health and smoking in Europe: Comparing different indicators of socioeconomic status
BACKGROUND: Although there is evidence for socioeconomic inequalities in health and health behaviour in adolescents, different indicators of socioeconomic status (SES) have rarely been compared within one data sample. We examined associations of five SES indicators with self-rated health (SRH) and smoking (ie, a leading cause of health inequalities) in Europe. METHODS: Data of adolescents aged 14-17 years old were obtained from the 2013 SILNE sur…
Academic performance and adolescent smoking in 6 European cities: The role of friendship ties
Poor academic performance is a known risk factor for adolescent smoking, yet the association remains unclear, as the role of social ties has been rarely examined. Our study aims to investigate the role of friendship ties in this association. In a sample of 11,015 adolescents, aged 14 to17, in 50 schools within six European cities (SILNE-survey, 2013), we used multilevel models to analyse the mediating effect of the composition of friendship ties …
School smoking policies and educational inequalities in smoking behaviour of adolescents aged 14–17 years in Europe
BACKGROUND: Studies on the effects of school smoking policies are inconclusive and there is no research on whether the effects of school policies vary by educational level. We examined the association between school smoking policies and smoking behaviour among adolescents aged 14-17 years in Europe and assessed educational inequalities in these associations. METHODS: Data on 10,325 adolescents from 50 schools in six European cities were obtained …
Evolution of socioeconomic inequalities in smoking: Results from the Portuguese national health interview surveys
Inequalities have been increasingly unfavourable to the worse-off in Portugal, although better-off women are still more likely to smoke. Worrisome inequality trends have been observed among the youngest generations, which call for the rapid implementation of equity-oriented tobacco control policies
Impact of the Medical Home Model on the Quality of Primary Care: The Belgian Experience
BACKGROUND: The Belgium medical home (MH) model, which has been garnering support of late, resembles its US counterpart in that it aims at improving the quality of health care while containing costs. OBJECTIVES: To compare the quality of care offered by MHs with that offered by traditional individual practices (IPs) in Belgium in terms of the extent of their adherence to clinical practice guidelines in antibiotherapy, cervical-cancer screening, i…
Direct treatment costs of HIV/Aids in Portugal
OBJECTIVE To analyze the direct medical costs of HIV/AIDS in Portugal from the perspective of the National Health Service. METHODS A retrospective analysis of medical records was conducted for 150 patients from five specialized centers in Portugal in 2008. Data on utilization of medical resources during 12 months and patients’ characteristics were collected. A unit cost was applied to each care component using official sources and accounting data…
Medical Homes Versus Individual Practice in Primary Care: Impact on Health Care Expenditures
BACKGROUND: The medical home (MH) model has prompted increasing attention given its potential to improve quality of care while reducing health expenditures. OBJECTIVES: We compare overall and specific health care expenditures in Belgium, from the third-party payer perspective (compulsory social insurance), between patients treated at individual practices (IP) and at MHs. We compare the sociodemographic profile of MH and IP users. RESEARCH DESIGN:…
Gender disparities in health and healthcare: Results from the Portuguese National Health Interview Survey
Although women experience poorer health conditions during their lives, they live longer than men. The main explanations for this paradox suggest that women's excess of ill-health is limited to minor illnesses and their different attitudes toward health. The authors test these assumptions by investigating disparities between men and women in health and healthcare in Portugal. Data are used from the Portuguese National Health Interview Survey 2005/…
