Impact of the COVID-19 pandemic on emergency department visits: experience of a Brazilian reference center

Regional disparities in BCG vaccination coverage and tuberculosis incidence in infants among Brazilian states

Bacillus Calmette-Guerin (BCG) vaccination and tuberculosis (TB) incidence in children under 1 year of age are critical public health indicators in Brazil. The coronavirus disease 2019 pandemic disrupted vaccination coverage (VC), potentially impacting TB incidence. Understanding regional disparities in VC and TB incidence can inform targeted interventions. We conducted an observational and ecological study using BCG vaccination data (2019-21) and TB incidence (2020-22) for all births in Brazil. Data were collected from public health databases, stratified by state, and analyzed using descriptive and analytical statistics to explore VC and TB incidence. Between 2019 and 2021, average BCG VC was 79.59%, with significant variation among states (P < .001). Only four states achieved minimum recommended coverage (>90%). TB incidence varied significantly among states (P = .003). There was a notable decline in VC from 2019 (90.72%) to 2021 (78.67%) (P < .001). This study highlights regional disparities in BCG VC and TB incidence among Brazilian states. Lower VC post-pandemic may increase TB incidence, requiring targeted interventions in states with inadequate coverage. The findings underscore the importance of sustaining vaccination programs amidst public health crises and implementing strategies to enhance access and uptake.

Does Covid-19 influence the dynamics of envenomation by animals in a country strongly affected by both conditions? Epidemiological data from Brazil

The impact of Covid-19 on envenomations by venomous animals in countries heavily affected by both conditions has not been quantified yet. Brazil shows high incidence of envenomations by scorpions, spiders and snakes and was heavily affected by waves of Covid-19. To determine how the pandemic impacted the epidemiology of envenomations by those three groups of venomous animals, we used online databases from two surveillance sources on number of cases and mortality. During the years before and during the pandemic, scorpion stings typically occurred in adults of both sexes in urban zones in the Southeast and Northeast regions. Spider bites occurred mainly in the South region, in adults of both sexes in urban zone. Snakebites affected mainly rural adult men in the Amazon. Between 2007 and 2021, overall incidence of cases by scorpions, spiders and snakes decreased after the beginning of the pandemic, snakebites did not show changes after the pandemic started in Brazil, but cases by scorpions and spiders decreased. No changes in the incidence of deaths were observed. On national level, Covid-19 affected some demographic, clinical and epidemiological aspects in cases by scorpions, spiders and snakes.

Demand for emergency services during the COVID-19 pandemic and disease burden: a case study in Portugal

Background

The COVID-19 pandemic brought changes in the pattern of care use. A significant increase in the volume of emergencies was expected. However, a significant decrease was observed worldwide.

Methods

An observational, analytical and cross-sectional study of all records of emergency episodes of patients aged 18 years or older admitted to the emergency services of the University of Porto Hospital Centre (2018-2022) were analysed.

Results

During the pandemic, a significant reduction in emergency episode admissions (up to 40% during lockdowns), an increase in pre-emergency services, and discharges from Infectious Diseases and Internal Medicine was observed. The discharges from General Practice and General Practice and Family Medicine were residual.

Conclusion

The lower use and type of use of emergency services during the COVID-19 pandemic had a negative impact on the disease burden. This could be prevented in future pandemics through the development of strategies to promote confidence in the use of health resources and establishing contingency plans for virtual assistance.

COVID-19 pneumonia assessed at a private hospital, a field hospital, and a public-referral hospital: population analysis, chest computed tomography findings, and outcomes

Objective

To compare a private quaternary referral hospital, a public tertiary hospital, and a field hospital dedicated to patients with COVID-19, regarding patients' characteristics, clinical parameters, laboratory, imaging findings, and outcomes of patients with confirmed diagnosis of COVID-19.

Methods

Retrospective multicenter observational study that assessed the association of clinical, laboratory and CT data of 453 patients with COVID-19, and also their outcomes (hospital discharge or admission, intensive care unit admission, need for mechanical ventilation, and mortality caused by COVID-19).

Results

The mean age of patients was 55 years (±16 years), 58.1% of them were male, and 41.9% were female. Considering stratification by the hospital of care, significant differences were observed in the dyspnea, fever, cough, hypertension, diabetes mellitus parameters, and CT score (p < 0.05). Significant differences were observed in ward admission rates, with a lower rate in the private hospital (40.0%), followed by the public hospital (74.1%), and a higher rate in the field hospital (89.4%). Regarding intensive care unit admission, there was a higher rate in the public hospital (25.2%), followed by the private hospital (15.5%), and a lower rate in the field hospital (9.9%). In the analysis of the discharge and death outcomes, it was found that there was a higher number of patients discharged from the private hospital (94.2%), compared to the field hospital (90.1%) and public hospital (82.3%) and a higher number of deaths in the public hospital (17.7%) compared to the private hospital and field hospital (5.8 and 0% respectively).

Conclusion

The analysis of the data regarding the population treated with COVID-19 during the first wave in different levels of care in the public and private health systems in the city of São Paulo revealed statistically significant differences between the populations, reflecting distinct outcomes.

Impact of the COVID-19 pandemic on visits to the hospital emergency service in two hospitals in Spain, from March 14, 2020 to June 21, 2020

This study will describe trends in the use of emergency departments before and after the Spanish State of Alarm, especially in pathologies not directly related to this infection. A cross-sectional study was conducted of all visits to the emergency departments in two third-level hospitals in two Spanish communities during the Spanish State of Alarm, compared with the same period of the previous year. The variables collected included the day of the week, the time of the visit, the duration of the visit, the final destination of the patients (home, admission to a conventional hospitalization ward, admission to the intensive care unit, and death), and the diagnosis at discharge according to the International Classification of Diseases 10th Revision. During the Spanish State of Alarm period, an overall decrease in care demand of 48% was observed, which reached 69.5% in pediatric emergency departments. We also saw a drop of between 20 and 30% in time-dependent pathologies (heart attack, stroke, sepsis, poisoning). The decrease in overall attendance in the emergency departments and absence of serious pathologies, such as time-dependent diseases, observed during the Spanish State of Alarm compared to the previous year highlights the need to strengthen the messages addressed to the population to encourage them to seek care without delay in case of alarming symptoms and reduce the high morbidity and mortality rate if the diagnosis is delayed.

Differences in the characteristics and patterns of adult emergency department return visits before and after the coronavirus disease 2019 outbreak

BACKGROUND

Data about changes in the characteristics of ED return visits before and after the COVID-19 outbreak are limited. This study aimed to report the differences on utility in ED return visits after the COVID-19 outbreak.

METHODS

This retrospective cohort study was conducted from 2019 to 2020. Adult patients with ED return visits were included in the analysis. Variables including demographic characteristics, pre-comorbidities, triage levels, vital signs, chief complaints, management, and diagnosis were recorded and confirmed via a manual assessment.

RESULTS

The proportion of patients with ED visits decreased by 23%. Hence, that of patients with ED return visits also reduced from 2580 to 2020 patients (22%) after the COVID-19 outbreak. The average age (60-57.8 years) of patients with return visits was significantly younger, and the proportion of female patients decreased remarkably. Further, the proportion of patients with chronic pre-existing diseases at the return visit significantly differed after the COVID-19 outbreak. The proportion of patients with chief complaints including dizziness, dyspnea, cough, vomiting, diarrhea, and chills during the return visits significantly differed before and after the COVID-19 pandemic. In the multivariable logistic regression model, age, high triage level were significantly associated with unfavorable outcome return visit.

CONCLUSION

The use of services in the ED has changed since the COVID-19 outbreak. Hence, the proportion of patients with unplanned return visits within 72 h decreased. After the COVID-19 outbreak, people are now cautious whether they should return to the ED, as in the pre-pandemic situation, or just treat conservatively at home.

The impact of COVID-19 epidemic on emergency department visits of older patients in Taiwan

BACKGROUND

The number of emergency department (ED) visits has significantly declined since the COVID-19 pandemic. In Taiwan, an aged society, it is unknown whether older adults are accessing emergency care during the COVID-19 epidemic. Therefore, this study aimed to investigate the impact of COVID-19 on the ED visits and triage, admission, and intensive care unit (ICU) hospitalization of the geriatric population in a COVID-19-dedicated medical center throughout various periods of the epidemic.

METHODS

A retrospective chart review of ED medical records from April 9 to August 31, 2021 were conducted, and demographic information was obtained from the hospital's computer database. The period was divided into pre-, early-, peak-, late-, and post-epidemic stages. For statistical analysis, one-way analysis of variance followed by multiple comparison tests (Bonferroni correction) were used.

RESULTS

A statistically significant decrease in the total number of patients attending the ED was noted during the peak-, late-, and post-epidemic stages. In the post-epidemic stage, the number of older patients visiting ED was nearly to that of the pre-epidemic stage, indicating that older adults tend to seek care at the ED earlier than the general population. Throughout the entire epidemic period, there was no statistically significant reduction in the number of the triage 1& 2 patients seeking medical attention at the emergency department. In the entire duration of the epidemic, there was no observed reduction in the admission of elderly patients to our hospital or ICU through the ED. However, a statistically significant decrease was observed in the admission of the general population during the peak epidemic stage.

CONCLUSIONS

During the peak of COVID-19 outbreak, the number of ED visits was significantly affected. However, it is noteworthy that as the epidemic was gradually controlled, the older patients resumed their ED visits earlier that the general population as indicated by the surge in their number. Additionally, in the patient group of triage 1& 2, which represents a true emergency, the number did not show a drastic change.

Changes in the clinico-functional characteristics of stroke patients in the acute phase during the COVID-19 pandemic

OBJECTIVE

To compare the sociodemographic and clinico-functional characteristics of patients admitted to a stroke unit immediately before and during two different COVID-19 pandemic phases.

METHODS

This exploratory study was conducted in the stroke unit of a public hospital in Brazil. Patients consecutively admitted to a stroke unit for 18 months with primary stroke aged ≥20 years were included and divided into three groups: G1: Pre-pandemic; G2: Early pandemic; and G3: Late pandemic. The sociodemographic and clinico-functional characteristics of the groups were compared (α=0.05).

RESULTS

The study included 383 individuals (G1=124; G2=151; G3=108). The number of risk factors (higher in G2; p≤0.001), smoking (more common in G2; p≤0.01), type of stroke (ischemic more common in G3; p=0.002), stroke severity (more severe in G2; p=0.02), and level of disability (more severe in G2: p≤0.01) were significantly different among the groups.

CONCLUSION

A greater number of serious events and risk factors including smoking and higher level of disability was observed in patients in the beginning of the pandemic than in the late phases. Only the occurrence of ischemic stroke increased in the late phase. Therefore, these individuals may have an increased need for rehabilitation services monitoring and care during their lifespan. Additionally, these results indicate that health promotion and prevention services should be strengthened for future health emergencies.

The association of the COVID-19 outbreak with in-hospital mortality: A single-centre study from Indonesia

Objective

The early outbreak period of Coronavirus Disease (COVID-19) has affected the emergency department (ED) and hospital services in many countries. This study aimed to investigate the association between COVID-19 outbreak and in-hospital mortality in Jakarta, Indonesia.

Methods

This retrospective cohort study was conducted in a single-centre referral hospital in Jakarta, Indonesia. Data were collected between May and October 2020. All patients who visited the ED and required inpatient care during the early COVID-19 outbreak period at the study location (March to April 2020) were included in the exposure group. All patients who visited the ED and required inpatient care during the non-outbreak period (March to April 2019) were included in the non-exposure group. In-hospital mortality was the primary outcome, whereas other variables, such as sex, age, triage categories, trauma cases, referral cases, and ED length of stay (LOS), were measured to identify confounding and effect modifications. Multivariate logistic regression analysis was performed to assess this association.

Results

A total of 2,808 patients during the outbreak period and 2,423 patients during the non-outbreak period participated in the study. The odds of in-hospital mortality increased during the outbreak period compared to that during the non-outbreak period (odds ratio [OR], 1.41; 95%CI 1.04-1.91; p = 0.01) after adjusting for age, sex, triage categories, trauma case, ED LOS, and interaction between the outbreak period and ED LOS.

Conclusion

COVID-19 outbreaks have been associated with an increased risk of in-hospital mortality in referral hospitals in Jakarta, Indonesia.

Impact of the COVID-19 Pandemic on the Experiences of Hospitalized Patients: A Scoping Review

OBJECTIVE

This study aimed to identify the factors that exerted an impact on the experiences of hospitalized patients during the COVID-19 pandemic from the quality and safety perspectives.

METHOD

A scoping review that followed the 5 stages described by Arksey and O'Malley was used. A systematized search of original studies was conducted in 9 databases: PubMed/MEDLINE, BDENF, CINAHL, LILACS, SciELO, Embase, Scopus, Web of Science, and Google Scholar. The factors that exerted an impact on patients' experiences were summarized, considering the perspective of quality and patient safety in health institutions. The factors were categorized using the Content Analysis technique.

RESULTS

A total of 6950 studies were screened, and 32 met the eligibility criteria. The main factors that exerted an impact on the patients' experience were as follows: caregiver/family concern with the patients' well-being during hospitalization, search for alternative communication and interaction means between the patients and their family, and changes in health care organization. The restrictions inherent to the policy regarding visits and companions exerted a negative impact on the experiences, increasing the patients' feelings of loneliness and isolation. Negative impacts were also evidenced in the hospital admission and discharge process and in the limitation of treatment possibilities offered to the patients, because of contact restrictions.

CONCLUSIONS

The factors that exerted an impact on the patients' experiences permeate communication between professionals, patients, and family members, with implications for health care quality.
