Background: Understanding variability in prescribing patterns through comparative drug utilization studies can contribute to improve an efficient, effective and safe use of medicines.
Objectives: To perform a cross-country comparison of consumption patterns of ambulatory high expenditure therapeutic groups between Portugal and six European countries and simulate potential cost-saving scenarios through the adoption of the different prescribing patterns of studied countries.
Methods: Cross-country comparison of 2019 drug consumption patterns between Portugal, Denmark, England, Finland, the Netherlands, Norway, and Spain. Analysis comprised antihypertensive drugs, glucose lowering drugs (GLD), insulins, lipid lowering drugs (LLD) and oral anticoagulants. Cost-saving analysis were performed using the Portugal average annual cost/daily defined dose and the potential reduction in expenditure simulating other European countries consumption pattern scenarios.
Results: Portugal had the lowest consumption uptake of metformin and the highest consumption of GLD (30.1%) and LLD (8.5% <3%) fixed-dose combinations. Annual cost-savings scenarios showed that Portugal would have saved between 53 M€ and 305 M€ if it had the same prescribing patterns than Norway or the Netherlands, respectively.
Conclusions: Different utilization patterns across countries were found. Although Portugal has the lowest gross domestic product among the countries studied, it had the highest uptake of newly and costly drugs.

Background: The independent and interrelated long-term effects of the exposome such as air pollution, greenness, and ambient temperature on lung function are not well understood, yet relevant in the light of climate change.
Methods: Pre-bronchodilation FEV1 from five mature birth cohorts (N = 4724) and three adult cohorts (N = 6052) from five European countries were used to assess cross-sectional associations with air pollution, greenness, and ambient temperature, assigned to their residential address. All two-way interactions and square terms were a priori included in building the final elastic net regression model.
Enhancing information for action: A strategic tool for strengthening public health emergency management systems.
Int J Med Inform
January 2025
World Health Organization Headquarters Switzerland.
Background: This paper addresses the importance of timely and robust information systems that underpin emergency response decision-making, as evidenced during the COVID-19 pandemic in the WHO European Region. Recognizing the relevance of these systems, we propose the strengthening of national emergency response information management systems (ERIMS) within the broader digital health information system (HIS) framework. We aim to develop and present an innovative assessment tool designed to evaluate and assist in the strengthening of ERIMS, contributing to a more resilient and effective emergency response.
