Analysis of primary care of victims of interpersonal and self inflicted violence during the COVID-19 pandemic

OBJECTIVES

to analyze the epidemiological profile of aggression victims admitted at the emergency room on a trauma hospital during the COVID-19 pandemic, to compare these data in different restriction periods and with prepandemic data from the same service.

METHODS

cross-sectional study with probabilistic sampling using medical records of patients who were victims of aggression admitted at the hospital between June 2020 and May 2021. In addition to the epidemiological variables, other variables collected were the current restriction level, mechanism of aggression, resulting injuries and the Revised Trauma Score (RTS). The data was compared between the three restriction levels and the proportion of attendances during the study period was compared with the pre-pandemic study (December 2016 to February 2018).

RESULTS

the average age was 35.5 years, 86.1% of the patients were male and 61.6% of the attendances were due to blunt injury. The highest average of attendances per day occurred during the "yellow" restriction level (2.9), however there was no significant difference when comparing the restriction periods two by two. There was also no significant difference either in the analysis of the standardized residuals of the proportions of aggressions or the mechanism of aggression in the pre-pandemic and pandemic periods.

CONCLUSIONS

there was a predominance of attendances due to blunt trauma and in young male patients. There was no significant difference between the average daily attendance for aggression during the three restriction levels and between the proportion of attendances in the pre-pandemic and pandemic period.

Factors Associated with the Lifestyle of Pediatric Healthcare Professionals during the COVID-19 Pandemic

The objective of this study was to analyze the association between sociodemographic and occupational variables with the lifestyle of health professionals in pediatric units during the COVID-19 pandemic. A cross-sectional study was conducted with 407 health professionals working in four pediatric health units in the State of Bahia, northeast Brazil. The Fantastic Lifestyle Questionnaire and a questionnaire with sociodemographic and employment variables self-applied via Google Forms were used. The final binary logistic regression models revealed significant associations between those who received 3 to 5 minimum wages, without a marital relationship and with more than one employment relationship. Data suggest that these sociodemographic and occupational profiles are more exposed to risky lifestyle behaviors. The findings of this study demonstrated the need for greater attention to the health of health professionals in the pediatric field, as well as the promotion of initiatives that seek to value the work of these professionals and reduce the damage caused to their lifestyle, especially in a pandemic scenario.

Risk of SARS-CoV-2 infection among front-line healthcare workers in Northeast Brazil: a respondent-driven sampling approach

OBJECTIVES

We assessed the prevalence of SARS-CoV-2 infection, personal protective equipment (PPE) shortages and occurrence of biological accidents among front-line healthcare workers (HCW).

DESIGN, SETTING AND PARTICIPANTS

Using respondent-driven sampling, the study recruited distinct categories of HCW attending suspected or confirmed patients with COVID-19 from May 2020 to February 2021, in the Recife metropolitan area, Northeast Brazil.

OUTCOME MEASURES

The criterion to assess SARS-CoV-2 infection among HCW was a positive self-reported PCR test.

RESULTS

We analysed 1525 HCW: 527 physicians, 471 registered nurses, 263 nursing assistants and 264 physical therapists. Women predominated in all categories (81.1%; 95% CI: 77.8% to 84.1%). Nurses were older with more comorbidities (hypertension and overweight/obesity) than the other staff. The overall prevalence of SARS-CoV-2 infection was 61.8% (95% CI: 55.7% to 67.5%) after adjustment for the cluster random effect, weighted by network, and the reference population size. Risk factors for a positive RT-PCR test were being a nursing assistant (OR adjusted: 2.56; 95% CI: 1.42 to 4.61), not always using all recommended PPE while assisting patients with COVID-19 (OR adj: 2.15; 95% CI: 1.02 to 4.53) and reporting a splash of biological fluid/respiratory secretion in the eyes (OR adj: 3.37; 95% CI: 1.10 to 10.34).

CONCLUSIONS

This study shows the high frequency of SARS-CoV2 infection among HCW presumably due to workplace exposures. In our setting, nursing assistant comprised the most vulnerable category. Our findings highlight the need for improving healthcare facility environments, specific training and supervision to cope with public health emergencies.

[Social distancing as protection factor against COVID-19 in a non-metropolitan area in the State of Rio Grande do Sul, BrazilLas medidas de distanciamiento social como factor de protección contra la COVID-19 en el interior de Rio Grande do Sul, Brasil]

Objective

To estimate the SARS-CoV-2 seroprevalence in a non-metropolitan area (Vale do Rio Pardo) in the state of Rio Grande do Sul, Brazil, and determine the association between seroprevalence and adherence to social distancing measures.

Method

For the present population-based, cross-sectional study, data were collected in four stages from August to October 2020. SARS-CoV-2 seroprevalence was assessed using an IgG/IgM rapid test. Demographic, socioeconomic, clinical, and behavioral data were also collected, with administration of a three-question survey to determine adherence to social distancing measures with a focus on the level of social distancing practiced by participants, their routine activities, and circulation of people in the home. The association between sociodemographic data and social distancing was assessed using the chi-square test for linear trends in proportions, and the association between social distancing and seroprevalence was assessed using Poisson regression (95% confidence interval [95%CI]; P< 0.05).

Results

Of 4 252 tested and interviewed participants, 11.8% (95%CI: 10.8; 12.8) did not adhere to social distancing measures. The prevalence of a positive rapid test was 4.7% in participants who did not practice social distancing and 1.9% in participants who adhered to social distancing measures (P< 0.05). The variables male sex, age 20 to 59 years, having completed high school, monthly family income ranging from R$ 3 136.00 to R$ 6 270.00, and living in rural areas were associated with non-adherence to social distancing (P< 0.05). Adherence to all social distancing measures provided protection against SARS-CoV-2 infection (prevalence ratio: 0.37; 95%CI: 0.19; 0.73).

Conclusions

The results indicate a reduction in seroprevalence with the adherence to social distancing measures.

COVID-19 in northeast Brazil: first year of the pandemic and uncertainties to come

OBJECTIVE

To analyze the epidemic of COVID-19 in northeastern Brazil, one of the regions most affected by the virus.

METHODS

The official data for COVID-19, from March 2020 to March 2021 in the states of the Northeast Region (NE), were used. The analysis of capital cities and states for accumulated weekly cases and confirmed deaths was made using the JoinPoint Trend Analysis application.

RESULTS

In one year, the Northeast region reported 22.9% of the cases and 21.5% of the deaths in the country due to COVID-19. At the beginning of the pandemic, all states showed a growing number of cases, first in the capitals and then in the interior. Following this wave, decreases are observed in all states and their capitals, but with many still reporting a large number of cases. In the middle of the 2nd semester of 2020 the number of cases begins to increase again simultaneously in states and their capitals-some at explosive speed-especially in late 2020 and early 2021. A similar pattern is observed in deaths, which exceed or approach the peak seen in the first wave. In the first wave, all capitals and northeastern states adopted intense isolation measures. Fortaleza, Recife and Teresina reached the highest isolation index of all capitals, close to 0.60. This index decreases, with a slight growth trend until the end of December. With the exception of Fortaleza and Salvador, the other capitals fell to less than 0.40.

CONCLUSION

The Brazilian NE and the country are in increasingly complicated health, social and economic situations. It is necessary to speed up vaccinations and maintain non-pharmacological measures: face masks, social distancing measures and hygiene care, in addition to policies to protect workers who have lost their incomes and to subsidize small business owners.

Health collapse in Manaus: the burden of not adhering to non-pharmacological measures to reduce the transmission of Covid-19

ABSTRACT This article aims to compare the evolution of Covid-19 in Manaus and Fortaleza, two epicenters of the pandemic in 2020, analyzing legal measures by local governments and levels of social isolation. An algorithm was defined to calculate the Homestay Index (HSI), using data from the Google Mobility Report. We analyzed the decree’s timeline, the HSI evolution, the Covid-19 incidence and the number of deaths from March/2020 to January/2021. The population of Fortaleza was exposed to more consistent measures of social distancing than that of Manaus. Longer homestay was observed from March to May 2020 and Fortaleza achieved higher and more lasting levels. As of June 2020, the HSI fell, notably in Manaus, reaching levels below zero in late December. As an aggravating factor, the government decreed broad isolation in Manaus on December 23, 2020, but after protests it was repealed on December 26, 2020. A judicial decision determined the complete closure in Manaus on January 2nd 2021, but it was too late: the SUS collapsed with an exponential increase in deaths. In Fortaleza, the demand for health services was high, but under control. We consider that only the strict application of non-pharmacological measures and mass immunization can prevent further deaths.
