Abstract: COVID-19 is a disease caused by SARS-CoV-2, which has spread worldwide since the beginning of 2020. Several pharmaceutical and non-pharmaceutical strategies were proposed to contain the virus, including vaccination and lockdowns. One of the consequences of the pandemic was the denial or delay of access to convenient healthcare services, but also potentially the increase in adverse events within those services, like the number of hospital infections. Therefore, the main question here is about what happened to the performance of Portuguese public hospitals. The main goal of this work was to test if the Portuguese public hospitals’ performance has been affected by the SARS-CoV-2 pandemic. We used the Benefit-of-Doubt method integrated with the Malmquist Index to analyze the performance evolution over time. Then, we employed a multiple regression model to test whether some pandemic-related variables could explain the performance results. We considered a database of 40 Portuguese public hospitals evaluated from January 2017 to May 2022. The period 2017 to 2019 corresponds to the baseline (pre-pandemic), against which the remaining period will be compared (during the pandemic). We also considered fourteen variables characterizing hospital quality, ided into three main performance definitions (efficiency and productivity access safety and care appropriateness). As potential explanatory variables, we consider seven dimensions, including vaccination rate and the need for intensive care for COVID-19-infected people. The results suggest that COVID-19 pandemic features help explain the drop in access after 2020, but not the evolution of safety and appropriateness of care, which surprisingly increased the whole time.

Abstract: In recent years, the demand for health care has increased owing to the ongoing introduction of new health problems and the intensification of existing illnesses. As research in this area progresses, knowledge becomes the primary motivation for patients to adopt a better quality of life. Consequently, many health units have struggled to develop solutions to manage excessive demand while maintaining a high quality of service to enhance patient satisfaction and boost revenues. One of these tactics is using simulation models as a method of operational research to analyze the flow of patients and predict potential solutions to enhance resource efficiency while decreasing waiting time. This work aims to develop and demonstrate a simulation model that replicates the functioning of a hospital unit. For this purpose, data derived from the health services of the Imaging Department of a private hospital, located in Lisbon, Portugal, were used. This model will replicate the daily flow that this department is subjected to by its patients and personnel and depict how the system evolves due to the management of the department's number of resources and examination rooms. At the end of the analyses, several solutions are presented and discussed, from level to level, concerning improvements in the performance of services, resources and patients. However, only the increase in one unit of examination rooms translates into a huge positive impact on waiting times in the respective queues.

Abstract: How to evaluate local government or what really matters concerning local government evaluation and who cares about it are questions which are on the table currently across the world. This paper carry out a survey on the wide range of indicators and evaluation models of local government used worldwide and shows that they are based mainly on performance evaluation and financial sustainability ratios. We conclude that they address only part of the problem of strategic management, financing, and sustainable development issues of local government. In particular, the governance dimension is absent. Therefore, a broader vision is proposed that integrates our usual local government evaluation into the important issues of governance and sustainability. This article focus on “measuring what matters” in local government and presents the need of a new evaluation model, a Councils’ Sustainability Index, based on the integration of council’s financial performance with communities’ sustainability and governance dimensions. Thus, it might be an important contribution for the creation of a new paradigm on local government evaluation and councils’ strategic management. The Portuguese case is used to illustrate this purpose.

Abstract: The unprecedented global health crisis caused by COVID-19 is undoubtedly having a major impact on international tourism for two reasons. While the imposed travel restrictions have discouraged people from traveling, travelers are struggling with growing anxiety in coping with the new travel environment. We address the changing risk perceptions of travelers in the wake of the COVID-19 pandemic. Our primary objective is to identify and weigh significant emerging travel risks and develop a Risk Score Index to measure destination performance and strategic interventions for South African travelers. In this case, we used MACBETH and web-Delphi to construct that index with the help of 32 experts in the field. We found that the risks perceived by tourists are multifaceted and encompass categories, such as additional costs, exchange rates, and reimbursement-related factors. These three criteria are most important to the general perception of travel risk. We applied the developed risk assessment index to five destinations to assess their performance relative to the identified risks. The UK was the best-performing country.

Abstract: This paper considers “measuring what matters” in local government and applies a Council Sustainability Index (CSI) to all 308 Portuguese municipalities. Using a Multi-criteria Decision Analysis Methodology (MCDA), an additive evaluation model is applied which aggregates 25 indicators across four dimensions to assess Portuguese local government sustainability. A critical evaluation of performance is provided along with a financial sustainability analysis and governance evaluation, which identifies the chief factors which explain different councils’ performance. We show that this approach sheds new light on Portuguese local government evaluation. CSI breaks new ground and it is applicable mutatis mutandis to most local government systems worldwide.

Abstract: Patient satisfaction with healthcare provision services and the factors influencing it are be-coming the main focus of many scientific studies. Assuring the quality of the provided services is essential for the fulfillment of patients’ expectations and needs. Thus, this systematic review seeks to find the determinants of patient satisfaction in a global setting. We perform an analysis to evaluate the collected literature and to fulfill the literature gap of bibliometric analysis within this theme. This review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) approach. We conducted our database search in Scopus, Web of Science, and PubMed in June 2022. Studies from 2000–2021 that followed the inclusion and exclusion criteria and that were written in English were included in the s le. We ended up with 157 articles to review. A co-citation and bibliographic coupling analysis were employed to find the most relevant sources, authors, and documents. We ided the factors influencing patient satisfaction into criteria and explanatory variables. Medical care, communication with the patient, and patient’s age are among the most critical factors for researchers. The bibliometric analysis revealed the countries, institutions, documents, authors, and sources most productive and significant in patient satisfaction.

Abstract: Due to the COVID‐19 pandemic, most countries are exposed to unprecedented social problems in the current global situation. According to the official reports, it caused a dramatic increase of 44% in graduates' unemployment rate in Portugal. Moreover, from the human resource point of view, the whole of Europe is expected to face a shortage of 925,000 data professionals by 2025. Given the existing situations, the DataPro aims to propose a national-level reskilling solution in big data to mitigate both social problems of unemployability and the shortage of data professionals in Portugal. DataPro project consists of four dimensions, including an online portal for the hiring companies and unemployed graduates, along with a web-based analytics talent upskilling (ATU) platform empowered by an artificial intelligence recommender system to match the reskilled data professionals and the hiring companies.
