The COVID-19 pandemic has caused vast changes in the functioning of societies and economies, including restrictions on the use of rail transportation. As a result, the number of passengers has declined, and despite the lifting of restrictions, it is still difficult to estimate when and if passenger rail traffic will return to its pre-pandemic state. Therefore, it seems important to consider the following: how the pandemic has affected the transportation behavior patterns of residents and, above all, what should be done to encourage passengers to use rail transportation more often, which is more environmentally friendly and reduces greenhouse gas emissions. Thus, it seems important to consider what the “new normal” in rail transportation should look like. This article analyzes the number of passengers traveling by rail in eight European countries. This work considers quarterly data for 2013‒2019, combined passenger forecasts for 2020‒2021, and annual forecasts of rail passenger traffic until 2025 built using data for 2012‒2021.

Purpose: The purpose of the considerations presented in the paper was to examine the changes that occurred in both population and GDP size and in selected economic sectors as a result of the outbreak of the COVID-19 pandemic in the highlighted EU regions. Design/methodology/approach: The paper examined the impact of the COVID-19 pandemic on the population of selected EU regions, GDP in those regions, and the impact of the pandemic on the unemployment rate, the number of people at risk of poverty or social exclusion, the number of nights spent in overnight accommodations, the number of passengers traveling by air, the number of people who ordered goods or services online in the past year, and employment in high-tech sectors. The impact was examined by analyzing development trend models for selected variables and verifying the hypothesis of constancy of model parameters with the Chow test. Predictions of selected variables were also counted if there had been no pandemic and compared to actual values from the COVID-19 pandemic period. Findings: Not all regions were equally affected by the effects of the pandemic. This was undoubtedly influenced by the authorities' struggle with the effects of the pandemic, but also by the entrepreneurial spirit of the residents of the regions studied. Also in different spheres of economic life, the effects of the pandemic varied from negative to positive. Research limitations/implications: Further research should also include the other EU regions and more economic sectors, allowing us to group regions according to similarities in coping with the pandemic and calculate spatial correlations. A problem we may encounter is the lack of sufficient data, which may result in the exclusion of some regions and economic sectors from the study. Social implications: Through the research, we can highlight regions that are coping better with the effects of a pandemic, and this can inspire regions that are coping less well. In the future, regions can look up to the actions carried out by authorities in other regions to offset the effects of pandemics (or other disasters with global effects) and transfer them to their own region. Originality/value: The article compares regions within the boundaries of which are national capitals. It was shown which region did best in combating the effects of the pandemic and which did less well. The article also shows what the impact of the pandemic was on the various branches of the economy.

Purpose: This paper explores the enduring repercussions of the COVID-19 pandemic on global supply chains by investigating the experiences and adaptations of organizations in Poland, Georgia, and Turkey. It seeks to provide valuable insights into the long-term implications of the pandemic on supply chain management, with a focus on strategies and challenges faced by businesses in different regions. Design/Methodology/Approach: We conducted an extensive study utilizing an online questionnaire to gather primary data from a diverse sample of organizations in Poland, Georgia, and Turkey. This research approach is quantitative and comprehensively assess the pandemic's impact on supply chains. We analysed responses from a range of industries, enabling a holistic understanding of the topic. In addition to descriptive analysis, we conducted a comparative examination of the three countries using ANOVA (Analysis of Variance) to assess any significant differences among them. Furthermore, we employed Cramér's V, a robust statistical measure, to investigate associations between categorical variables within the dataset Findings: The research reveals that the outcomes in three distinct countries are surprisingly similar, contrary to initial expectations. The majority of the proposed COVID-19 factors exhibit no statistically significant distinctions among Poland, Georgia, and Turkey. Consequently, we can infer that the COVID-19 pandemic exerted a considerable and widespread impact on the entities under consideration. Research Limitations: Despite our efforts to gather a representative sample, the study may not encompass all industries and organizations equally. Additionally, the research is subject to the limitations of self-reported data and potential bias in responses. The focus on specific regions may not capture the entirety of global supply chain dynamics. Practical Implications: This research provides practical insights for organizations navigating supply chain challenges in a post-pandemic world. It offers guidance on building resilient and adaptable supply chains and managing risks effectively. Businesses can use these insights to make informed decisions and enhance their supply chain strategies. Originality/Value: Drawing from our own research conducted in three countries after the official conclusion of the pandemic, this study adds a distinctive contribution to the current body of literature. It takes a long-term perspective on the repercussions of the COVID-19 pandemic on supply chains, specifically emphasizing diverse regions. The employed methodology and regional comparisons offer a nuanced insight into the dynamic evolution of the supply chain landscape, underscoring the importance of adaptability and resilience. In contrast to various studies conducted at the onset and during the pandemic, this paper uniquely seeks to discern the enduring effects.

Purpose: The aim of the article is to analyze and assess the role of logistics in the process of enterprise management during the COVID-19 pandemic on the example of selected manufacturing, trade and service enterprises. Design/methodology/approach: The article is based on the study of literature and own empirical research. The results of own empirical research presented in the study constitute the effects of more extensive research on an in-depth analysis of the logistics process management in Polish manufacturing, trade and service enterprises in 2019-2021 in the context of shaping enterprise results. The research was conducted in 2022 among 335 randomly selected small, medium and large Polish manufacturing, trade and service enterprises. Findings: The results of the research show that the strategic and operational management of logistics processes within the enterprise and between entities which are the links in the supply chain increasingly determined the economic and market results of the best surveyed enterprises and the supply chains they created during the COVID-19 pandemic. Thanks to adequately applied logistics to the occurred conditions, the best surveyed enterprises responded quickly and appropriately to the effects of the pandemic and created and maintained the competitive advantage. The analyzed enterprises did not use the full potential of logistics processes to reduce the negative influence of the COVID-19 pandemic on their results. The research confirmed that logistics played an extremely important role in the process of enterprise management during the COVID-19 pandemic. Research limitations/implications: The article presents only selected aspects of logistics in the process of enterprise management of the surveyed enterprises during the COVID-19 pandemic. Practical implications: The article offers logistics managers practical suggestions on how to use logistics to achieve above-average economic and market results in conditions of a pandemic. Originality/value: The article fills the cognitive and empirical gap regarding logistics in the process of enterprise management during the COVID-19 pandemic.

Purpose: This paper attempts to reveal the potential differences between the portfolios of dividend-paying companies with growth or value potential and the same portfolios fortified with the financial instruments replicating precious metals or real estate price behavior in a turbulent global economy. Design/methodology/approach: The research objective of this paper is accomplished by means of a thorough literature analysis. Moreover, the authors employ comparative analysis methods to explore the features of stock portfolios held by dividend-paying companies with value or growth potential and portfolios of the companies that are fortified with financial instruments replicating the price behavior of precious metals or real estate and uncover the similarities and differences. Research of the characteristics of financial instrument portfolio variants and comparison between them is conducted by means of standard deviation of the rate of return, coefficient of variation, the Pearson correlation coefficient and the Spearman's rank correlation coefficient. It was also assessed whether the estimated correlation coefficients were statistically significant through the use of a non-parametric correlation coefficient significance test. Findings: The results of the empirical analyses conducted here reveal that the average annual return of portfolios held by dividend-paying companies with value and growth potential is lower than ETFs replicating precious metals. Furthermore, during the turbulent economy of 2020, the inclusion of precious metal assets boosted the rates of return of the Polish dividend-paying companies portfolios. Research limitations/implications: The research was carried out on a limited number of the analyzed companies. Therefore, it could be biased, due to the deterministic stock sampling method. Practical implications: Knowledge of the similarities and differences between dividend-paying companies with value or growth potential and the risk diversification of such companies’ stock portfolios by means of instruments replicating the price behavior of precious metals or real estate is of great importance to both the investors and investment funds' boards. Consequently, one can make better investment decisions. Social implications: Among the paper's social implications, the most important appears to be a possible change in the investors' attitude towards dividend-paying companies with value potential and financial instruments replicating the price behavior of precious metals or real estate. Ultimately, investors’ needs could be better addressed. Originality/value: What is new in the paper is the stock comparison of dividend-paying companies' with value and growth potential with precious metals and real estate-based instruments. The paper also attempts to compare efficiency of investing in the portfolio variants, capturing the effect of the SARS-CoV-2 pandemic, thereby filling our knowledge gap.

Pandemia COVID-19 spowodowała ogromne zmiany w funkcjonowaniu społeczeństw oraz wpłynęła na wiele aspektów życia, w tym na szkolnictwo wyższe. Wprowadzone po wybuchu pandemii obostrzenia zmusiły także wyższe uczelnie do przejścia na zdalną formę nauczania. Celem niniejszego artykułu jest przedstawienie wyników badań dotyczących tego, w jaki sposób nauczanie zdalne wpłynęło na motywację studentów do nauki, a także jak zmieniło się postrzeganie tej formy kształcenia po powrocie do nauczania stacjonarnego. Celem nie było jednak samo ustalenie faktu, ale oprócz tego poznanie opinii badanych w tym temacie w kontekście piramidy potrzeb A. Maslowa. Do badań wykorzystana została metoda badań ankietowych, czyli technika CAWI. Badana populacja składała się z 415 respondentów – studentów uczelni. Badania przeprowadzono w grudniu 2022 r., kiedy to studenci po półtorarocznej nauce w formie zdalnej powrócili do nauki w murach uczelni. Dobór próby był losowy. Wyniki badań pokazują, że studenci uznali formę zdalną zajęć za niekorzystnie wpływającą na motywację do nauki. Po dokonaniu szczegółowej analizy przeprowadzonych badań w kontekście piramidy potrzeb A. Maslowa opracowano propozycje udoskonalenia nauczania w formie zdalnej. Na każdym z poziomów zaproponowano wskazówki, które mogą przydatne w ulepszeniu tej formy kształcenia.

The COVID-19 pandemic caused huge changes in the functioning of societies and affected many aspects of life, including higher education. The restrictions introduced after the outbreak of the pandemic have also forced higher education institutions to switch to a remote form of teaching. The aim of this article is to present the results of a study on whether and how distance learning has affected students' motivation to learn, and how perceptions of this form of education have changed after the return to full-time teaching. However, the aim was not only to establish this fact, but also to find out the opinions of the respondents on this topic in the context of A. Maslow's pyramid of needs. The survey research method used for the study was the CAWI technique. The surveyed population consisted of 415 respondents – university students. The research was conducted in December 2022, when the students returned to study within the walls of the university after a year and a half of studying remotely. The sample selection was random. The results of the study show that students considered the remote form of classes as having a negative impact on their motivation to study. After a detailed analysis of the conducted research in the context of A. Maslow's pyramid of needs, proposals were developed for the improvement of remote learning. At each level, factors and aspects were proposed that could be a guide to improving this form of education.

In supply chain management, random events can occur that are difficult to predict. Once such event, the COVID-19 pandemic, affected supply chains around the world and forced companies to make sudden changes. Companies could still operate and deliver their products to customers through innovation, but also through the flexibility and innovation of transport enterprises. In the last two decades, the Polish transport industry has gained importance in the European Union. The main objective of this paper is to determine the specification of business operations under pandemic conditions, assess the impact of the pandemic on international transport SMEs in Poland, and then identify key challenges for the industry from the point of view of entrepreneurs. To this end, a literature review, desk research and snowball sampling were carried out towards the end of 2021 and beginning of 2022. The research results show that changes in the organisation of supply chains, diversification, changes in demand and other effects of the pandemic have had a positive impact on the operations of some transport companies in Poland, and the larger the company, the more these changes have been used in a positive way for the business operations of transport. This seems to be confirmed by statistical data. The biggest beneficiaries of the changes seemed to have been medium-sized and large companies. Micro enterprises, on the other hand, most often assessed the impact of the pandemic negatively. In addition, the challenges relating to the amount of fines in transport, indicated most often in our survey by the entrepreneurs, certainly also hit the micro-enterprises the hardest.

W zarządzaniu łańcuchem dostaw mogą wystąpić zdarzenia losowe, które trudno przewidzieć. Pandemia dotknęła łańcuchy dostaw na całym świecie i zmusiła firmy do nagłych zmian. Firmy nadal mogą działać i dostarczać swoje produkty klientom dzięki innowacyjności, ale także elastyczności i innowacyjności przedsiębiorstw transportowych. W ciągu ostatnich dwóch dekad polska branża transportowa zyskała na znaczeniu w Unii Europejskiej. Głównym celem niniejszego artykułu jest określenie specyfiki funkcjonowania przedsiębiorstw w warunkach pandemii, ocena wpływu pandemii na MŚP transportu międzynarodowego w Polsce, a następnie identyfikacja kluczowych wyzwań dla branży z punktu widzenia przedsiębiorców. Korzystano z przeglądu literatury, desk research i badania metodą kuli śniegowej przeprowadzonego na przełomie 2021 i 2022 r. Wyniki badań pokazują, że zmiany w organizacji łańcuchów dostaw, dywersyfikacja, zmiany popytu i inne skutki pandemii pozytywnie wpływają na działalności niektórych firm transportowych w Polsce, a im większa firma, tym bardziej te zmiany są wykorzystywane w pozytywny sposób w działalności firm transportowych. Wydaje się, że potwierdzają to także dane statystyczne. Największymi beneficjentami zmian wydają się być firmy średnie i duże. Mikroprzedsiębiorstwa najczęściej negatywnie oceniają wpływ pandemii. Najczęściej wskazywane przez przedsiębiorców wyzwania związane z wysokością kar w transporcie z pewnością również są bardzo odczuwane przez mikroprzedsiębiorstwa.

The COVID-19 pandemic is undoubtedly a global crisis that has forced the world economy to a standstill. Subsequent lockdowns have caused downtime in all industries and all transportation sectors. The removal of the restrictions has made it possible to begin a slow return to pre-pandemic conditions, but research indicates that this will be a long process. Therefore, an indication of the development trends of passenger maritime transport in Poland, considering the impact of the COVID-19 pandemic, is the purpose of the article. Two specific objectives are identified: (1) To visualize the impact of the COVID-19 pandemic on passenger maritime transport in Poland; (2) To make long-term forecasts of passenger maritime traffic in Poland. The analyses showed that the COVID-19 pandemic had a very negative impact on passenger streams. It may take several more years to recover from the pre-pandemic state.

Purpose: The paper aims to identify how and where elements of digital transformation of activities implemented in enterprises can increase the resilience of the production system to pandemic threats. Design/methodology/approach: The paper presents the selected results of a survey conducted using the mixed-mode CATI and CAWI on a representative group of 600 manufacturing enterprises in Poland. An analysis of measures used in the case of COVID-19 infections in the company to support business continuity and enhance resilience was carried out. A quantitative evaluation of the collected data, oriented to identify the level of application of emergency response measures, was conducted, including the support of statistical tools (Statistica software). Findings: The study identified dozens of different measures implemented in manufacturing enterprises. Among the measures studied, there were those related to automation and digitalization of activities in the organization of production processes. The data analysis showed that there were significant correlations between the type of measures used, as well as the characteristics of the enterprises, and the production processes implemented in them. Research limitations/implications: Future studies should also include companies with a high degree of automation and digitization of production. In addition to descriptive analysis, a quantitative-statistical approach should be used. Practical implications: On the practical side, it was pointed out how and where elements of digital transformation of activities implemented in enterprises can increase the resilience of the production system to pandemic threats. Digitization and automation measures should be used by managers to support the implementation of production processes also in the context of improving the efficiency of enterprises. Social implications: Enterprises can use the study results to improve business continuity policies and preparing for threats similar to the COVID-19 pandemic. Originality/value: The novelty of the survey is the comprehensive assessment of the use of solutions from the ICT area in manufacturing enterprises, analyzed in different cross sections (size, industry, occurrence of the COVID-19 case).

Purpose: Financial crises, stock market crashes and consequently bursts of speculative enthusiasm have been accompanying investors since the 17th century. The first speculative bubble, so-called “tulip mania”, occurred in the Netherlands between 1636 and 1637, while a speculative “fever” spread among the shareholders of the Dutch East India Company from 1636 to 1640. Those events exposed remarkable possibilities and complexity of the financial markets, and later encouraged investors to explore a variety of investment strategies bringing above-average rates of return. However, the question remains: how do modern-day investors react to the market disruptions and which investment strategies are popular among them. The purpose of this paper is to provide an understanding of how and why the COVID-19 pandemic affected the investors’ behavior and the rates of return earned by selected WSE listed companies. An attempt was also made to estimate the sensibility of investing in selected stocks through the use of the basic and most popular fundamental analysis market ratios, i.e. P/E and P/BV. Furthermore, based on selected companies, semi-strong information efficiency of the Polish stock market was assessed, with a particular focus on the COVID-19 pandemic period. Methodology: The paper assesses the rates of return of companies constituting the WIG20 index and selected “covid” companies and calculates P/E and P/BV market ratios to verify how the fundamentals of a given company affect its rates of return. As a measure of relationship strength between the market value and rate of return indicators, the Spearman's rank correlation coefficient and a significance test for the Spearman's rank correlation coefficient were selected. Findings: The research reveals that, during times of violent turmoil and massive panic on the stock markets, an interesting investment strategy that brings above-average rates of return is to build a stock portfolio based on a current trend. All hypotheses formulated were positively verified in the paper. Practical implications: The study's results provide a valuable source of information for stock market investors, particularly individual investors who, when making tough investment decisions, i. e. during stock market crashes or financial crises, can employ strategies that involve building an investment portfolio based on trending companies and achieve above-average rates of return. Furthermore, the suggested investment strategy is adaptable and, over centuries, still effective. Originality: The considerations concentrated not only on identifying an appropriate investment strategy in times of a stock market turmoil, but largely focused around behavioral aspects of investing, which represent an important addition to theories about rational decision-making by investors and the efficiency of financial markets.

This paper focuses on the impact of COVID-19 on energy companies in terms of implementing their environmental strategies and continuing the low-emission transformation of their generating units in conditions of their financial results' instability. Nonlinear panel model is estimated for energy companies listed on the Warsaw Stock Exchange, whose generations units have been included in EU ETS in the years 2009-2021. The estimation results indicate the existence of a U-shaped relationship between the CO2 intensity observed one year earlier and current asset returns, which can be explained by the 'too-little-of-a-good-thing' effect. It indicates that companies with proactive environmental strategies that are intensively involved in the low-carbon transformation processes of energygenerating facilities achieve increasingly better financial performance. The inclusion of pandemic shocks in the modelling has not changed the shape of the CEP-CFP relationship, but it has been observed that during this period, carbon-intensive energy companies achieved lower returns on assets. A new environmental variable was considered, namely the emission to allowances index, which, together with the variable describing the share of renewable energy in energy production, informs about the degree of low-emission transformation of electricity generation.

W artykule oceniono wpływ pandemii COVID-19 na przedsiębiorstwa energetyczne w zakresie realizacji strategii środowiskowych i kontynuacji niskoemisyjnej transformacji jednostek wytwórczych w warunkach niestabilności ich wyników finansowych. Skonstruowano i oszacowano nieliniowy model panelowy dla spółek energetycznych notowanych na Giełdzie Papierów Wartościowych w Warszawie, których jednostki wytwórcze zostały objęte systemem EU ETS w latach 2009-2021. Wyniki estymacji wskazują na istnienie zależności w kształcie litery U pomiędzy obserwowaną rok wcześniej intensywnością emisji CO2 a bieżącą stopą zwrotu z aktywów, co można wytłumaczyć efektem „za mało dobrych rzeczy” ('too-little-of-a-good-thing'). Wskazuje on, że firmy posiadające proaktywne strategie środowiskowe, intensywnie angażujące się w procesy niskoemisyjnej transformacji jednostek wytwórczych, osiągają coraz lepsze wyniki finansowe. Uwzględnienie w modelowaniu oddziaływania szoków pandemicznych nie zmieniło kształtu relacji CEP-CFP, jednak zaobserwowano, że w tym okresie przedsiębiorstwa energetyczne o wysokiej intensywności emisji CO2 osiągały niższe zwroty z aktywów. Do badania zaproponowano nową zmienną środowiskową, opisującą relację między rzeczywistą emisją spółek a przyznanymi darmowymi uprawnieniami do emisji, która wraz ze zmienną opisującą udział energii odnawialnej w produkcji energii, informuje o stopniu niskoemisyjnej transformacji przedsiębiorstw.

The condition of the Coronavirus Disease 2019 (COVID-19) pandemic in 2020 characterizing DKI Jakarta, Surabaya, and Yogyakarta Provinces which have a high population density in 2019, necessitates implementing Large-Scale Social Restrictions (LSSR) to control or break the chain of the spread of COVID-19. The LSSR policy that limits community activities, be it business activities, transportation, and the industrial sector, will impact social activities and the environment due to the reduced intensity of community activities. Therefore, this study aimed to determine changes in the carbon monoxide (CO) levels in Jakarta, Surabaya and Yogyakarta during the pre-pandemic and during the pandemic. The method used is the tropospheric CO concentration extracted from the Sentinel-5P satellite data. The CO data were retrieved and calculated using Google Earth Engine. The COVID-19 pandemic reduced CO level by 19.7%, 14.9%, and 21%, respectively. The paired t-test shows no significant difference from before the COVID-19 pandemic, with a significance of 0.05. The highest pre-pandemic average and total CO concentration levels were 0.042 and 1.0198 mol/m2 in Yogyakarta, respectively, whereas the lowest during the pandemic were 0.02845 and 0.6828 mol/m2 in Surabaya. Overall, the three cities have a weak relationship between CO level and precipitation as well as temperatures and CO level.

The COVID-19 pandemic has significantly and permanently changed modern life in the private and professional dimensions, where numerous consequences of the virus have affected employees and employers. Both groups were forced to implement numerous changes to ensure the work process’s safety. The multi-dimensionality of this concept and, consequently, the multi-directionality of its potential and required actions taken by companies have become the basis for a theoretical and practical analysis of conditions for supporting broadly understood employee safety during the COVID-19 pandemic in selected production companies in Poland. The pilot studies’ results indicated the leading direction and scope of actions taken so far, their main types, stimulating factors and barriers, perceived benefits and future trends. The article’s conclusions may form the basis for universal good practices supporting the safety of employees in the production sector, which, regardless of the duration of the pandemic, may be used as effective and efficient improvement measures in generating measurable benefits for all stakeholders.

Emissions from transport account for 20-25% of anthropogenic global carbon dioxide emissions [17, 37], with more than 70% coming from road transport, making it an extremely important topic in the context of decarbonization. The aim of the article is to analyze the trend of CO2 generated from road transport, taking into account various sources, and also to examine how reduced mobility during the pandemic affected the emissions at the time. For this purpose, a time series containing observations up to the pandemic outbreak and a time series containing additional observations from the pandemic period were analyzed. For each time series, a trend was determined and described by a polynomial and then verified to see if the pandemic phenomenon significantly affects a parameter of the proposed model, using appropriate statistical tests.

Odkąd w latach 80. Roger Ulrich zapoczątkował badania wpływu elementów środowiska zbudowanego na pacjentów, zmieniło się podejście architektów do projektowania szpitali. Zaczęli oni dążyć do tworzenia środowisk terapeutycznych (ang. Healing Environment), ośrodków, które są nie tylko przestrzenią do realizacji procedur medycznych, ale również tymczasowym mieszkaniem pacjentów oraz miejscem pracy personelu. Warunki pobytu oraz wyraz architektoniczny budynku szpitala mają ogromny wpływ na wydajność leczenia, co rzutuje chociażby na długość i koszty hospitalizacji. Dlatego tak ważne jest, aby znać potrzeby użytkowników i tę wiedzę wykorzystywać przy projektowaniu coraz bardziej przyjaznych dla ludzi, a zarazem bardziej efektywnych szpitali. Jednak w obliczu pandemii COVID-19 należy zastanowić się, jak projektować budynki służby zdrowia, aby pogodzić ograniczanie zakażeń wewnątrzszpitalnych z tworzeniem środowisk terapeutycznych. Niniejszy artykuł jest jednym z etapów w dążeniu do odpowiedzenia na to pytanie. Przedstawia, jakie zmiany zaszły w szpitalach, z perspektywy pacjentów wraz ze stosowanymi w walce z pandemią przekształceniami funkcjonalnymi, przestrzennymi czy proceduralnymi, jakie potrzeby stały się trudne lub niemożliwe do zrealizowania. Poza przeglądem literatury tematu przedstawiono wyniki przeprowadzonych na przełomie 2021 i 2022 roku wywiadów dotyczących doświadczeń pacjentów hospitalizowanych przed pandemią oraz po jej wybuchu. Zestawienie wyników pozwoliło zidentyfikować największe przeciwności powstałe w wyniku pandemii, będące często w opozycji do nowoczesnego projektowania szpitali.

Since the 1980s, when Roger Ulrich initiated research on the impact of the architectural environment on patients, architects' approach to hospital design has changed. They have begun to strive for the creation of Healing Environments - centers that are not only spaces for medical procedures but also temporary homes for patients and workplaces for medical staff. The conditions of stay and the architectural expression of the hospital building have a huge impact on the effectiveness of treatment, which affects, among other things, the length and cost of hospitalization. Therefore, it is important to know the needs of users and use this knowledge to design increasingly people-friendly and efficient hospitals. However, in the face of the COVID-19 pandemic, it is necessary to consider how to design healthcare buildings to reconcile the limitation of nosocomial infections with the creation of Healing Environments. This article is one of the steps towards answering this question. It presents the changes that have occurred in hospitals from the perspective of patients, along with the functional, spatial, and procedural transformations applied in the fight against the pandemic and identifies the needs that have become difficult or impossible to meet. In addition to a literature review, it presents the results of interviews conducted in 2021 and 2022 on the experiences of patients hospitalized before and after the outbreak of the pandemic. The analysis of the results allowed to identify the biggest obstacles resulting from the pandemic, which often stand in opposition to modern hospital design.
