Background: The transferability of health policies in the European Union (EU) faces challenges due to economic, political, and healthcare system factors, including cross-country differences in health preferences. In order to aid policymaking, previous research has grouped EU countries based on geographical proximity or literature-based criteria, but not on health preference data. The EQ-5D-5L instrument, which measures health-related quality of life and reflects unique national health preferences shaped by cultural and social factors, is used to evaluate policies, technologies and interventions, but has not been used to group countries.

Introduction: Economic arguments in favour of investing in health and health care are important for policy making, yet demonstrating the potential economic gains associated with health at older ages can be empirically challenging due to older peoples' limited attachment to the labour market.

Methods: We develop a novel method to quantify the economic value of health through time use data. Using data on people aged 65 years-old and older from the United Kingdom Time Use Survey (UKTUS) 2014-15, we apply survey-weighted generalized linear models to predict the time spent in non-market productive activities conditional on characteristics including age and self-perceived health.

Background: In Portugal, trained physicians undertake the clinical coding process, which serves as the basis for hospital reimbursement systems. In 2017, the classification version used for coding of diagnoses and procedures for hospital morbidity changed from the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) to the International Classification of Diseases, Tenth Revision, Clinical Modification/Procedure Coding System (ICD-10-CM/PCS).

Objective: To assess the perceptions of medical coders on the transition of the clinical coding process from ICD-9-CM to ICD-10-CM/PCS in terms of its impact on data quality, as well as the major differences, advantages, and problems they faced.

Objectives: Within the framework of the burden of disease (BoD) approach, disease and injury burden estimates attributable to risk factors are a useful guide for policy formulation and priority setting in disease prevention. Considering the important differences in methods, and their impact on burden estimates, we conducted a scoping literature review to: (1) map the BoD assessments including risk factors performed across Europe; and (2) identify the methodological choices in comparative risk assessment (CRA) and risk assessment methods.

Methods: We searched multiple literature databases, including grey literature websites and targeted public health agencies websites.

Trust in institutions is a key driver to shape population attitudes and behavior, such as compliance of non-pharmaceutical interventions (NPI). During the COVID-19 pandemic, this was fundamental and its compliance was supported by governmental and non-governmental institutions. Nevertheless, the situation of political polarization in some countries with decentralized health systems increased the difficulty of such interventions.

Introduction: In Portugal, a reform to implement Long-term mental health care (LTMHC) started in 2017 allowing patients with severe mental illness receiving psychosocial rehabilitation to regain their autonomy and be reintegrated into their communities.

Aim: To describe the first steps of the Portuguese LTMHC implementation and to assess the relationship between the LTMHC's demand (referrals) and supply (vacancies and occupancy).

Methods: We conducted a national retrospective observational study to analyse the LTMHC referrals, vacancies and occupancy between mid-2017 (LTMHC establishment) and December 2022.

Introduction: Healthcare expenditure, a common input used in health systems efficiency analyses is affected by population age structure. However, while age structure is usually considered to adjust health system outputs, health expenditure and other inputs are seldom adjusted. We propose methods for adjusting Health Expenditure per Capita (HEpC) for population age structure on health system efficiency analyses and assess the goodness-of-fit, correlation, reliability and disagreement of different approaches.

With the increasing influx of patients and frequent overcrowding, the adoption of a valid triage system, capable of distinguishing patients who need urgent care, from those who can wait safely is paramount. Hence, the aim of this study is to evaluate the validity of the Paediatric Canadian Triage and Acuity Scale (PaedCTAS) in a Portuguese tertiary hospital. Furthermore, we aim to study the performance and appropriateness of the different surrogate severity markers to validate triage.

Article Synopsis
  • This review looked at how researchers in Europe study the concept of disability-adjusted life years (DALY) for infectious diseases.
  • They found 105 studies that met their criteria, with most focusing on food- and water-borne diseases.
  • The number of these studies has grown, particularly from 2015 to 2022, and there's a need for better guidelines to help make results more comparable.

The need to control the sanitary situation during the COVID-19 pandemic has led governments to implement several restrictions with substantial social and economic impacts. We explored people's trade-offs in terms of their income, life restrictions, education, and poverty in the society, compared to their willingness to avoid deaths. We applied a web-based discrete choice experiment to elicit preferences of the Portuguese citizens for these attributes and computed the marginal rate of substitution in terms of avoided deaths.
