Second Half Of March Research Articles

TikTok in Spanish University Libraries

Goals: The objective of this paper is to describe the characteristics of the profiles and publications of Spanish university libraries on TikTok: to what extent they are present in this medium, what their posts are like, the topics they cover and how many interactions they receive, in order to identify good practices to help other libraries. Methodology: Eight university library profiles on TikTok were analyzed in the second half of March 2023, all of which were active at the time of the analysis,. Quantitative data such as the number of posts or the number of followers were captured. Quantitative and qualitative data were also extracted from each of the 207 publications in the accounts from their creation date until February 28, 2023, such as their duration or topic or the interactions they received. Results: The results provide information about the presence of Spanish university libraries on TikTok, which is still scarce but is increasing. Variables such as the frequency of publication, video length, video content, the number of views, the interactions they receive and the engagement rate are analyzed. Two university libraries with the best audience engagement on TikTok were identified. The characteristics of the ten posts with the most views and interactions are analyzed. All of them share the mixture of information about the library, transmitted through a short and simple message, with a humorous, fun or informal approach. Some follow fashion trends on TikTok.

Seasonality of Oestrus ovis infection in sheep in the steppe zone of the Stavropol Territory

The purpose of the research is to study the seasonality of Oestrus ovis infection in sheep depending on the management conditions in the steppe zone of the Stavropol Territory.Materials and methods. The research to study the botfly flight seasonality was conducted on two farms in the Apanasenkovsky District and two farms in the Ipatovsky District of the Stavropol Territory. The number of sheep botflies was studied in the entire flight season by regular inspection and counting of the parasite adult stage on the outer surfaces of sheephouse walls and the side walls of sheds with a 15 day-interval.Results and discussion. The sheep botfly flight season was 5.5 months (from May 25–30 to October 31–November 11). Two increases in the number of botflies were observed during this period: in July and September–October. Infection of sheep with oestrosis in 1971 had two peaks (the first, May to June; the second, August to November). Due to the earlier spring 2022, the first peak started in the second half of March and lasted until the first half of July, and the second peak was observed from the second half of August to the end of November.

Extended access to general practice services during weekends in the first wave of the COVID-19 pandemic.

The incidence, symptoms, and trajectories of COVID-19 in the community were unknown in the early phase of the pandemic. Consequently, organizing a primary health care response was challenging. The aim of this study was to investigate whether reorganizing general practice services with extended weekend access for patients was feasible, and to assess the extent to which patients used this service. Observational study with registration after a simple intervention. General practice services in the second half of March 2020 when the first wave of the COVID-19 pandemic hit Bergen, the second largest city in Norway. All general practices in Bergen were asked to be available during weekends for their patients with respiratory tract infections (RTIs), by telephone, video-, or e-consultation. Number of practices participating, patients connected to these practices, and consultations for RTIs and suspected COVID-19. During the first weekend, 33 of 71 practices (45%) covering 51% of the population participated. The following weekend this increased to 39 practices (53%) covering 64% of the population. The first weekend 25 practices reported a total of 336 consultations for RTIs, eight of which were for confirmed and 113 were for suspected COVID-19. The corresponding numbers reported from 23 practices the second weekend were 158 RTI consultations, four for confirmed and 41 for suspected COVID-19. On short notice about half the practices in Bergen were made accessible during weekends for their patients with RTIs. The number of consultations per practice was small, but combined this amounted to a substantial improvement in the emergency services.

Quantifying forest resilience post forest fire disturbances using time-series satellite data.

Quantification of forest resilience will help us to manage the sustainability of the forest environment and the safety of biodiversity. Measuring forest resilience is crucial for ensuring long-term health of the forest ecosystem in the face of ongoing environmental changes and disturbances. This study focuses on providing a framework to estimate forest resilience scores to assess the vegetation condition after a disturbance. The resilience calculation framework provided uses number of recovery days, the phenological performance level of vegetation in the year when the disturbance took place, long-term mean phenological performance, and greenness levels in subsequent year to calculate the final resilience score at each pixel. Recovery of forests using Landsat data with the help of Normalized Difference Vegetation Index or Normalized Burn Ratio poses a challenge for continuous monitoring of forested landscapes due to cloud cover and availability of scenes at continuous intervals in Landsat datasets. In this regard, MODIS 16-day EVI products were used in this study (2001 to 2020) for monitoring vegetation health before, during, and after the disaster. Bandhavgarh National Park (BNP) located in Madhya Pradesh, India is considered for this study as it witnessed major forest fire breakouts in the second half of March 2018. The objectives of the study are the following: (1) to estimate post-fire recovery days and (2) to formulate new resilience index. The study revealed that the northern part of BNP is more vulnerable and shows slow recovery. The relationship between occupation of people living inside and in the neighboring area with forest resilience is also investigated in this study.

Inpatient covid-19-related comorbidities and ct-semiotics

Introduction. In the Russian Federation, registration of individual COVID-19 cases started at the end of January 2020 that markedly increased in the second half of March. At the moment, the situation with COVID-19 is unstable. As of 2023, COVID-19 incidence in descending order is as follows: USA (104 958 987 people), India (44 684 775 people) and France (39 582 057 people). Russia ranked 10th regarding total COVID-19 incidence (22 137 084 people, including 395 727 fatalities). The infection is able to “overlap” with the underlying pathology, thereby worsening patient’s condition up to death. Lung multislice computed tomography (MSCT) is recommended for all patients with COVID-19. If unavailable, a chest X-ray is performed. The aim of the study was to identify the most frequent comorbid diseases and changes on radiological scan in patients with COVID-19.Materials and methods. The study was carried out at the Infectious Disease Department No. 1, Regional Public Health Institution “Clinical Hospital No. 1” Smolensk. For this, there were analyzed 69 hospital patient records with basic diagnosis — coronavirus infection. The data of anamnesis and additional instrumental investigations were taken into account.
 Results. 69 patients aged between 18 and 91 years were included in the study. Respiratory failure was not observed in 75.81% of cases. A group of patients (66.67%) with comorbidities of organs and systems was identified, among which most common were: arterial hypertension (95.65%), coronary heart disease (78.26%), diabetes mellitus (30.43%), grade 1–2 obesity (17.39%), chronic hepatitis (17.39%). Diseases of the gastrointestinal tract and respiratory system were less prevalent. The rate of reported complications is as follows: bilateral polysegmental pneumonia — 72.46%; unilateral polysegmental pneumonia — 2.8%; pleurisy — 4.35%; unilateral hydrothorax — 1.45%. Each of the inpatients underwent radiological examination during hospitalisation. X-ray examination accounted for a smaller proportion (39.13%) and multispiral chest computed tomography (MSCT) — for a bigger percentage (60.87%). Chest MSCT at the beginning of inpatient treatment visualized CT-2 stage (64.29%) in the vast majority, less — CT-1 (26.19%), least frequently — CT-3 (7.14%) and CT-4 (2.38%). Before patient discharge, an average of 12.16% improvement in the radiological picture was found in patients with initial CT-1 stage, 14% — in CT-2, 12% and 26% — in CT-3 and CT-4, respectively.Conclusion. The moderate disease course without respiratory depression prevailed among the patients. Co-morbidities were found mainly in the anamnesis of persons over 50 years old. The most frequent clinical complication of coronavirus infection was bilateral pneumonia. After patient’s hospitalization, clinical and instrumental picture gradually improved, which was confirmed by radiological data.

Field and Laboratory Observations on the Biology of Aceria angustifoliae with Emphasis on Emergence of Overwintering Mites.

Data on the life strategy of A. angustifoliae (population fluctuation in buds and on leaves, emergence and migration to the overwintering sites), as well as its temperature-dependent emergence from overwintering sites at constant temperatures, were determined. The eriophyid mite overwintered into buds and the density of active mites inside them from winter 2017 to spring 2018 was higher than that in winter 2018-spring 2019. In the second half of March 2018 and in winter 2018-spring 2019, the mite density inside the buds decreased gradually with a peak of emergence occurring at the beginning of plant blossoming. Population density on leaves increased in summer, reaching a higher and later peak in 2018, and gradually decreased in autumn with mites migrating to overwintering sites. A lower developmental threshold of 4.5 °C was calculated. About half of the mite population was estimated to emerge from the overwintering sites at an accumulation of degree days ranging, on average, between 85.5 (at 20 °C) and 104.4 (at 10 °C) degree days above the assessed threshold.

First sequenced cases of Omicron BA.2 sublineage in Ecuador

The largest wave of infection with SARS-CoV-2 virus in Ecuador was observed in mid-December 2021 and early January 2022, driven by B.1.1.529/BA (Omicron) variant. During the second half of March, an increase in the number of daily cases was observed and coincided with the emergence of the BA.2 variant, which we describe in the present study. The first sequenced five cases of SARS-CoV-2 21L/BA.2 in Ecuador were identified using variant specific genotyping by qPCR and confirmed by whole genome sequencing (WGS). The first sequenced Ecuadorian BA.2 isolate was obtained from a person with international travel history who became symptomatic 3 days after travelling, whereas in the other cases no travel history was recorded.

Impact of water level on spring bird assemblages in a natural river valley in central Europe

Water level appears to be crucial for waterbirds, especially in the changeable conditions prevailing in river valleys. One of the best preserved Central European rivers is the Biebrza in north-eastern Poland, which seasonally overflows in spring, creating optimal habitats for various waterbirds. We examined a number of environmental factors which could strongly influence different foraging groups and bird assemblages with respect to water surface area and depth. Number of waterbirds peaked during the second half of March, when a large wave of geese and ducks stopped over there. The species diversity was the greatest in the first half of April, when more species arrived from their wintering grounds. We did not find any relationship between water depth and total abundance, but the former did significantly influence the numbers of some ecological feeding groups of waterbirds, i.e. diving omnivores, diving carnivores and surface carnivores. We assume that higher water level in a river valley is favourable to birds during their spring passage, because it creates areas of shallow floodwater that are intensively used by many different aquatic species. Owing to the well-preserved hydrological conditions and its full protection as a national park, the Biebrza valley not only offers optimal conditions for migratory waterbirds, but is also a good research area for studies of the phenomena taking place in avian communities during their migratory staging.

Detection of Temporal Shifts in Semantics Using Local Graph Clustering

Many changes in our digital corpus have been brought about by the interplay between rapid advances in digital communication and the current environment characterized by pandemics, political polarization, and social unrest. One such change is the pace with which new words enter the mass vocabulary and the frequency at which meanings, perceptions, and interpretations of existing expressions change. The current state-of-the-art algorithms do not allow for an intuitive and rigorous detection of these changes in word meanings over time. We propose a dynamic graph-theoretic approach to inferring the semantics of words and phrases (“terms”) and detecting temporal shifts. Our approach represents each term as a stochastic time-evolving set of contextual words and is a count-based distributional semantic model in nature. We use local clustering techniques to assess the structural changes in a given word’s contextual words. We demonstrate the efficacy of our method by investigating the changes in the semantics of the phrase “Chinavirus”. We conclude that the term took on a much more pejorative meaning when the White House used the term in the second half of March 2020, although the effect appears to have been temporary. We make both the dataset and the code used to generate this paper’s results available.

Poseta kralja Petra I Karađorđevića Carigradu 1910. godine

The visit of King Petar I Karađorđević to the Turkish sultan is one of the eight visits in modern Serbian history. Seven meetings of Serbian rulers with sultans took place in Constantinople, except for one that took place in Bulgaria. In the visits made before 1878, the Serbian rulers went as vassals. The meeting between the Serbian king and Sultan Mehmed V Rešad in 1910 was the third in a row since Serbia became an independent state. King Petar I Karađorđević spent the second half of March and the first half of April 1910 travelling. First, he visited Russia, then Constantinople, Mount Athos, and finally Thessaloniki. The trip lasted a little over 24 days, six of which he spent in Constantinople. The Serbian delegation led by the king was warmly received by the sultan, the common people, and the Christian population living in the Turkish capital. Upon their return, the members of the delegation were convinced that Turkey would remain on the path of improving Serbian-Turkish relations, friendly agreement, and strengthening of economic relations. This intention was highlighted in the official statement of the Porte published on the occasion of the visit of the Serbian king. In the announcement, it was expressly emphasized that a complete agreement was reached at the conferences of the foreign ministers of the two countries and that the Turkish side will grant Serbian wishes for strengthening economic and trade relations. It was of great importance for the Kingdom of Serbia to remove the obstacles that existed until that time regarding the construction of the Adriatic railway. In addition, practical results were achieved because Turkish officials expressed their readiness for the greatest possible benefits that would contribute to the export of Serbian goods through Thessaloniki. The visit to Constantinople brought success in the issues regarding religion as well, because after four years of resistance, the Patriarchate and the Synod, just before the king's arrival, accepted the election of the Serb Varnava Rosić as bishop of the Veles-Debar eparchy. The meeting of the two rulers received great attention in the diplomatic circles of European countries, especially Austria-Hungary. The relations between Serbia and the Ottoman Empire, apart from the economic aspect, soon fell into the shadows due to the Albanian riots and rebellions that engulfed the entire Kosovo vilayet. In that case too, the Serbian state tried not to interfere in Turkey's internal affairs.

Domestic violence calls for police service in five US cities during the COVID-19 pandemic of 2020

BackgroundWhen COVID-19 stay-at-home orders were instituted, there were concerns that isolation may lead to increases in domestic violence (DV). Reports of increased rates of DV during the stay-at-home period have been suggestive of this but inconsistent across different locations. We sought to complement the existing studies by characterizing changes in DV trends in US cities of Chicago, Los Angeles (LA), New York City (NYC), Philadelphia, and Phoenix using police call volume data from January 1st, 2018, through Dec 31st, 2020.MethodsThe stay-at-home orders were generally instituted for most US states in the second half of March 2020. We used the call volume for the pre-COVID-19 period (Jan. 2018 to Feb. 2020) to model a forecast against the stay-at-home order period (Mar. - May 2020) and the period after lifting the order (June – Dec. 2020) using the interrupted autoregressive integrated moving average (ARIMA) time series model.ResultsDuring the stay-at-home order, increases in mean DV calls relative to pre-COVID-19 were observed in Chicago (47.8%), Phoenix (18.4%), NYC (3.5%), and LA (3.4%), but a decrease in Philadelphia (-4.9%). After lifting the stay-at-home order, changes in mean calls relative to pre-COVID-19 remained elevated in Chicago, slightly elevated in Phoenix, and returned to baseline in NYC and LA.ConclusionResults suggest that the stay-at-home orders may have contributed to an increase in DV calls in some cities (Phoenix, and to a smaller extent LA, NYC), but the increase seen in Chicago (and to some extent Phoenix) persisted beyond the stay-at-home order and therefore may not be attributable to the stay-at-home orders. Additional studies are needed to help explain why the association between stay-at-home orders and DV police call volume seems to only appear in some locations.

THE MOST COMMON CONCERNS OF LECTURERS REGARDING THE TEACHING OF SERBIAN AS A FOREIGN LANGUAGE

The subject of this paper is the analysis and classification of the most common doubts of linguists, researchers and teachers-practitioners in the field of methodology of teaching Serbian as a foreign language. The aim of this paper is to consider and find possible solutions. In this paper, we used the descriptive method and the method of theoretical analysis with the technique of content analysis. We conducted detailed qualitative and quantitative research. The material for the research consisted of posts (and comments) in a group on Facebook called Serbian Language for Foreigners: a group for lecturers. In two years the group gathered more than two thousand linguists, researchers and teachers-practitioners. A survey conducted in the second half of March 2022 showed us that all doubts and all questions can be classified into six major groups: 1) organisational issues of teaching Serbian as a foreign language, 2) issues related to the processing of materials and contents, 3) announcements of lectures, summer schools and webinars dedicated to this type of teaching, 4) business offers for teachers of Serbian as a foreign language, 5) interesting facts about learning Serbian and 6) tips for writing scientific research papers. In the end, we have tried to offer (potential) answers to the questions asked and clearly formulated doubts.

Phylogeography and genomic epidemiology of SARS-CoV-2 in Italy and Europe with newly characterized Italian genomes between February-June 2020

The aims of this study were to characterize new SARS-CoV-2 genomes sampled all over Italy and to reconstruct the origin and the evolutionary dynamics in Italy and Europe between February and June 2020. The cluster analysis showed only small clusters including < 80 Italian isolates, while most of the Italian strains were intermixed in the whole tree. Pure Italian clusters were observed mainly after the lockdown and distancing measures were adopted. Lineage B and B.1 spread between late January and early February 2020, from China to Veneto and Lombardy, respectively. Lineage B.1.1 (20B) most probably evolved within Italy and spread from central to south Italian regions, and to European countries. The lineage B.1.1.1 (20D) developed most probably in other European countries entering Italy only in the second half of March and remained localized in Piedmont until June 2020. In conclusion, within the limitations of phylogeographical reconstruction, the estimated ancestral scenario suggests an important role of China and Italy in the widespread diffusion of the D614G variant in Europe in the early phase of the pandemic and more dispersed exchanges involving several European countries from the second half of March 2020.

Structural Breaks in Interactive Effects Panels and the Stock Market Reaction to COVID-19

Dealing with structural breaks is an essential step in most empirical economic research. This is particularly true in panel data comprised of many cross-sectional units, which are all affected by major events. The COVID-19 pandemic has affected most sectors of the global economy; however, its impact on stock markets is still unclear. Most markets seem to have recovered while the pandemic is ongoing, suggesting that the relationship between stock returns and COVID-19 has been subject to structural break. It is therefore important to know if a structural break has occurred and, if it has, to infer the date of the break. Motivated by this last observation, the present article develops a new break detection toolbox that is applicable to different sized panels, easy to implement and robust to general forms of unobserved heterogeneity. The toolbox, which is the first of its kind, includes a structural change test, a break date estimator, and a break date confidence interval. Application to a panel covering 61 countries from January 3 to September 25, 2020, leads to the detection of a structural break that is dated to the first week of April. The effect of COVID-19 is negative before the break and zero thereafter, implying that while markets did react, the reaction was short-lived. A possible explanation is the quantitative easing programs announced by central banks all over the world in the second half of March.

РИНОК ПРАЦІ ТА ЗАЙНЯТІСТЬ УКРАЇНИ В УМОВАХ ВІЙНИ

The article analyzes the state of the labor market of Ukraine, which functions in conditions of war. It was substantiated that the majority of enterprises were not ready for the worst scenario of the development of events despite the formation of a threatening situation and military escalation near the Ukrainian borders. Quite a large share of such enterprises slowed down or suspended their activities. The companies of the IT sector, as well as those that were able to organize remote work and in which the relocation is not connected with the movement of significant production capacities, received a smaller shock. It was determined that during the first month of the war, the Ukrainian economy halved, which caused changes in the labor market. According to the survey results, on average, 53% of the surveyed respondents lost their jobs due to hostilities in the country (a total of 1000 respondents were surveyed). The biggest problem is in the east, where this indicator reaches 74%. In the first weeks after the start of the war, all online job search platforms saw a significant decrease in the number of open vacancies and resumes posted on them. In Ukraine, the number of resumes has critically decreased. There have been changes in internal migration, as well as population migration abroad. According to UN data, more than 4 million Ukrainians are seeking asylum in neighboring countries. The mass movement of the population to the western regions of Ukraine has led to a sharp increase in the shortage of personnel in the vitally necessary areas of the market in the areas covered by hostilities. The shock period on the labor market did not last long, and already in the second half of March there were signs of its gradual adaptation to the conditions of the new socio-economic reality. It was found that the most in demand on the modern labor market are specialists in the fields of agriculture, transport and logistics, as well as sales (salespeople, cashiers, etc.). The demand for medical workers and pharmacists has also increased. The fact that the RussianUkrainian war will significantly change not only the domestic, but also the global labor market is indisputable. One of the industries that can become a driver of further recovery and development of the domestic economy can be the IT industry. In addition, further development of various formats of remote work should be expect. Also, the need to restore the housing stock, rebuild domestic enterprises and infrastructure facilities creates favorable conditions for the intensive development of the construction industry. Undoubtedly, professions related to the security and defense sector, medicine, psychology, energy, logistics, etc. will be in demand.

The role of emission reductions and the meteorological situation for air quality improvements during the COVID-19 lockdown period in central Europe

Abstract. The lockdown measures taken to prevent a rapid spreading of the coronavirus in Europe in spring 2020 led to large emission reductions, particularly in road traffic and aviation. Atmospheric concentrations of NO2 and PM2.5 were mostly reduced when compared to observations taken for the same time period in previous years; however, concentration reductions may not only be caused by emission reductions but also by specific weather situations. In order to identify the role of emission reductions and the meteorological situation for air quality improvements in central Europe, the meteorology chemistry transport model system COSMO-CLM/CMAQ was applied to Europe for the period 1 January to 30 June 2020. Emission data for 2020 were extrapolated from most recent reported emission data, and lockdown adjustment factors were computed from reported activity data changes, e.g. Google mobility reports. Meteorological factors were investigated through additional simulations with meteorological data from previous years. The results showed that lockdown effects varied significantly among countries and were most prominent for NO2 concentrations in urban areas with 2-week-average reductions up to 55 % in the second half of March. Ozone concentrations were less strongly influenced (up to ±15 %) and showed both increasing and decreasing concentrations due to lockdown measures. This depended strongly on the meteorological situation and on the NOx / VOC emission ratio. PM2.5 revealed 2 %–12 % reductions of 2-week-average concentrations in March and April, which is much less than a different weather situation could cause. Unusually low PM2.5 concentrations as observed in northern central Europe were only marginally caused by lockdown effects. The lockdown can be seen as a big experiment about air quality improvements that can be achieved through drastic traffic emission reductions. From this investigation, it can be concluded that NO2 concentrations can be largely reduced, but effects on annual average values are small when the measures last only a few weeks. Secondary pollutants like ozone and PM2.5 depend more strongly on weather conditions and show a limited response to emission changes in single sectors.

ХАРАКТЕРИСТИКИ АНТИЦИКЛОНИЧЕСКОГО ВИХРЯ, СФОРМИРОВАВШЕГОСЯ У ТИХООКЕАНСКОГО ПОБЕРЕЖЬЯ ЮЖНЫХ КУРИЛ ВЕСНОЙ 1999 г.

Based on the analysis of oceanographic survey materials and sea surface temperature satellite observations, the conditions of formation and characteristics of the anticyclonic eddy located in the region of the South Kuril Islands in the spring of 1999 were studied. It was shown that it separated from the subarctic front as result of its interaction with the Oyashio current stream in the second half of March and ceased to exist in mid-June, which is also confirmed by observations of the concentration of chlorophyll-a. In contrast the eddies formed as a result of meandering of the warm Kuroshio and Tsugaru currents, the eddy core, located at depths of 150–300 m, was characterized by lower values of temperature and salinity (4°–4.6°С and 33.55–33.65 е.п.с.) and low current velocities ( about 10 cm/s). The eddy was rather weakly distinguished in the density field both on horizontal and vertical distributions, as well as according to satellite altimetry data.

Fashion and Beauty Influencers and Romanian Millennials: Exploring the Dynamics of Consumer Behavior

"Studies have found that product-related information from social media influencers can shape millennial consumers’ purchasing behavior. This research investigates, in a descriptive approach, how Romanian millennials relate to content provided on social media platforms by influencers they prefer and follow. The study also shows factors that influence trust in this dynamic. Using data collected through an online-administered survey in the second half of March 2020, the authors found that Facebook, Instagram, and YouTube were the top preferred platforms providing the much-desired video content by influencers. Romanian millennials use this content frequently to make informed purchasing decisions, and they value honest recommendations and opinions, lending trust to experienced influencers, who seem to have qualified voices. They also show confidence towards the influencer to whom they can relate, and the one who is actively involved with their community. For Romanian millennials, the influencers’ notoriety measured by the number of followers is an artefact of their quality content, and their confidence is boosted by influencers who show clear, real, and satisfactory results when using products that they are advertising. Marketers, thus, should be cognizant of the elements of trust that can translate online reviews by influencers into purchasing behavior, and can design strategies that rely on actual product benefits demonstrated by influencers. Keywords: social media influencers, Millennials, consumer behavior, fashion and beauty, trust. "

The Impact of COVID-19 on Psychiatric Emergency and Inpatient Services in the First Month of the Pandemic in a Large Urban Mental Health Hospital in Ontario, Canada.

The World Health Organization characterized COVID-19 (coronavirus disease 2019) as a pandemic on March 11, 2020 (WHO). Within a couple of days, all Canadian provinces announced the implementation of social distancing measures. We evaluated the immediate effect of COVID-19 on psychiatric emergency and inpatient services in Canada's largest psychiatric hospital in the first month of the pandemic. We extracted data from the electronic medical records of the Center for Addiction and Mental Health in Toronto, Canada. We compared emergency department visits, inpatient occupancy rates, and length of stay in March 2019 and March 2020, and during the first and second half of March 2020. There was a decrease in the number of emergency department visits and inpatient occupancy rates in March 2020 compared to March 2019. There was also a significant decrease in the number of emergency department visits and inpatient occupancy rates in the second half of March 2020 compared to the first half. Our findings suggest that the pandemic was followed by a rapid decrease in the usage of psychiatric emergency and inpatient services in a large mental health hospital. Future studies will need to assess whether this decrease will be followed by a return to baseline or an increase in need for these services.
