Has the COVID-19 pandemic changed existing patterns of non-COVID-19 health care utilization? A retrospective analysis of six regions in Europe.

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.

Regional health care profiles - an improved method for generating case studies on the catchment areas of envisaged primary health care units in Austria: a report to the InfAct Joint Action.

BACKGROUND: The recent Austrian Primary Care Act established new primary health care units (PHCUs) and obliged them to draw up a "care strategy" specifying their focal care tasks and objectives and emphasizing the health care needs of the population in their catchment area with its specific local health and epidemiological profile. The main purpose of these care strategies is thus to ensure that care-providers meet the local needs, but they also provide a rationale for evaluation and organizational development. To assist new PHCUs in establishing care strategies it was necessary to develop a method for automatically generating comprehensive local case studies for any freely definable location in Austria. RESULTS: We designed an interactive report generator capable of producing location-specific regional health care profiles for a PHCU located in any of Austria's 2122 municipalities and of calculating the radius of its catchment area (defined by different levels of maximum car-travelling times). The reports so generated, called "regional health care profiles for primary health care" (RHCPs/PHC), are in comprehensive PDF report format. The core of each report is a set of 35 indicators, classified under five health and health service domains. The reports include an introductory text, definitions, a map, a graphic and tabular presentation of all indicator values, including information on local, supra-regional and national value distribution, a ranking, and numbers of service providers (e.g. pharmacies, surgeries, nursing homes) located within the catchment area. CONCLUSIONS: The RHCPs/PHC support primary health care planning, efforts to improve care-effectiveness, and strategic organizational development by providing comprehensive information on the health of the population, the utilization of health services and the health care structures within the catchment area. In addition to revealing the scope and nature of the health care needed, they also provide information on what public health approaches are necessary. RHCPs/PHC for different locations have already been distributed to numerous stakeholders and primary health care providers in Austria.

Innovative use of data sources: a cross-sectional study of data linkage and artificial intelligence practices across European countries.

BACKGROUND: The availability of data generated from different sources is increasing with the possibility to link these data sources with each other. However, linked administrative data can be complex to use and may require advanced expertise and skills in statistical analysis. The main objectives of this study were to describe the current use of data linkage at the individual level and artificial intelligence (AI) in routine public health activities, to identify the related estimated health indicators (i.e., outcome and intervention indicators) and health determinants of non-communicable diseases and the obstacles to linking different data sources. METHOD: We performed a survey across European countries to explore the current practices applied by national institutes of public health, health information and statistics for innovative use of data sources (i.e., the use of data linkage and/or AI). RESULTS: The use of data linkage and AI at national institutes of public health, health information and statistics in Europe varies. The majority of European countries use data linkage in routine by applying a deterministic method or a combination of two types of linkages (i.e., deterministic & probabilistic) for public health surveillance and research purposes. The use of AI to estimate health indicators is not frequent at national institutes of public health, health information and statistics. Using linked data, 46 health outcome indicators, 34 health determinants and 23 health intervention indicators were estimated in routine. The complex data regulation laws, lack of human resources, skills and problems with data governance, were reported by European countries as obstacles to routine data linkage for public health surveillance and research. CONCLUSIONS: Our results highlight that the majority of European countries have integrated data linkage in their routine public health activities but only a few use AI. A sustainable national health information system and a robust data governance framework allowing to link different data sources are essential to support evidence-informed health policy development. Building analytical capacity and raising awareness of the added value of data linkage in national institutes is necessary for improving the use of linked data in order to improve the quality of public health surveillance and monitoring activities.

Medical radiation exposure from radiological and interventional procedures in Austria.

BACKGROUND: The aim of the study was to systematically evaluate the frequency of diagnostic and interventional X­ray procedures and the corresponding population exposure in Austria. DATA AND METHODS: A methodology based on 107 selected procedures was adopted in accordance with European Commission recommendations. Frequencies were calculated based on an Austrian nationwide standardized database for the outpatient and inpatient sectors. The collective effective dose was estimated by linking the procedure frequencies to results from previous studies on doses per procedure and correction factors from the European Commission. RESULTS: In Austria, 1468 diagnostic and interventional X­ray procedures per 1000 inhabitants were conducted in 2015. Plain radiography procedures were performed most frequently, with approximately 40% being dental radiographs. The estimated extrapolated collective effective dose for 2015 was approximately 12,890 man-sievert (1.5 mSv per head). Although computed tomography only constitutes about 11% of the total number of procedures, its contribution to the collective effective dose is by far the largest at 74%, followed by plain radiography at almost 10%. CONCLUSION: This study provides a comprehensive estimate of procedure frequencies in Austria based on annually available, routinely collected data and of the corresponding collective effective dose. The results show that the frequency of computed tomography in Austria more than doubled within the last 14 years and is high compared to Germany and Switzerland. As in other countries, computed tomography is the largest contributor to the collective effective dose, identifying it as an area that deserves special attention for dose optimization.

Pre-coverage assessments of new hospital interventions on Austria: methodology and 3 years of experience.

OBJECTIVES: A new decision-making process was set up by the Austrian Ministry of Health to regulate coverage of new proposed Extra Medical Services (EMS; German: Medizinische Einzel-Leistung [MEL]) in 2008. As part of the annual decision-making process an independent academic institution (LBI-HTA) is evaluating relevant evidence on these new technologies and provides HTAs, including evidence-based recommendations for decision makers. METHODS: About ten EMS assessments are performed annually by the LBI-HTA simultaneously between January and March. Each peer-reviewed report consists of a systematic literature review and critical appraisal of evidence using the GRADE methodology. The generation of numerous reports of good quality standards within the short timeframe is achieved by a standardized workflow with predefined assignment of tasks for all participants. RESULTS: In total, the LBI-HTA performed twenty-five EMS assessments on thirty-three different interventions in the last three years. Coverage was recommended with limitation for eleven (33%) interventions, and not recommended for twenty-two (66%) interventions. The federal health commission decided on acceptance or preliminary acceptance of coverage in seven (22%) cases, rejection in eighteen (55%) cases and changed the status to "subject to approval" in seven (24%) cases. CONCLUSIONS: Pre-coverage assessment of new hospital interventions was implemented successfully in Austria. It has proved to be a useful tool to support decision makers with objective evidence when deciding whether or not to reimburse medical services.

[Types of medical registries - definitions, methodological aspects and quality of the scientific work with registries]. / Formen medizinischer Register - Definitionen, ausgewählte methodische Aspekte und Qualität der Forschung mit Registern.

This work presents a comprehensive list of registry definitions including broader and narrower definitions. Compared to each other different methodological issues can be identified. Some of these issues are common for all registry types; some can be assigned more easily to a specific registry type. Instruments for evaluating the quality of registers reflect many of the mentioned aspects. Generally, and especially at registers with a descriptive or exploratory research dimension it is important to consider their intended purpose and in about it was achieved. This includes, for instance, whether the purpose and the methodology are coordinated. From the start of registration an initiator should be - based on the purpose - aware of the methodological dimension of the registry. This helps to apply the correct type of the registry, the appropriate guidance and, ultimately, the arguments for the effort (cost-benefit ratio).
