ABSTRACT BACKGROUND: A bibliometric analysis covering only the production of original studies or considering world production until 2022 has yet to be conducted. The creation and advancement of vaccines have also influenced research priorities, demonstrating the need for a new approach to this subject. OBJECTIVES: To analyze worldwide scientific production related to coronavirus disease 2019 (COVID-19) and the aged and to describe what has already been produced. DESIGN AND SETTING: Bibliometric analysis with a quantitative approach. METHOD: The search terms “COVID-19,” “SARS-CoV-2,” “Aged,” and “Elderly” were used to retrieve articles from the Web of Science database. A total of 684 articles were included in the analysis. Data were imported into RStudio Desktop Software and linked to R Software. The Bibliometrix R package and VOSviewer software were used for analysis. RESULTS: Most articles were published in 2020. These were produced by 4,937 authors and published in 379 journals. The keyword most used by the authors was “COVID-19.” Publications from 77 countries were obtained. China had the highest article production ranking, and Spain collaborated the most. The articles addressed the implications of the pandemic on the aged, the relationship between vaccination in the aged, and the implications for the disease itself. CONCLUSION: Further research should be conducted, mainly concerning vaccines and vaccination of the aged, owing to the need for and importance of immunization in this risk group, including assessing the long-term effects of vaccines.

RESUMEN Objetivo: comparar los niveles de estrés ex-post-fact entre los profesionales de enfermería en el ambiente del trabajo hospitalario participantes de intervención educativa con profesionales de enfermería en actividades laborales. Materiales y método: estudio observacional y transversal. La muestra final se compuso por 30 profesionales de enfermería, de la que 15 profesionales compusieron el grupo expuesto a intervención y 15 se seleccionaron por muestreo aleatorio para componer el grupo no expuesto. La intervención consistió en un programa, con enfoque en el trabajador, estructurado en cuatro sesiones, aplicado en formato de curso, con periodicidad quincenal y duración de dos meses. En la comparación entre los grupos, se utilizaron la prueba t de Student para amuestras independientes y la prueba U de Mann-Whitney. Resultados: por medio de la prueba U de Mann-Whitney, se puede comparar el nivel de estrés entre los grupos, en el que se observó diferencia estadística del nivel de estrés entre el grupo control (3,34 ± 0,71 u.a.) y el grupo intervención (2,52 ± 0,59 u.a.) (p = 0,002; d = 1,26). Conclusiones: comparando el nivel de estrés general entre los grupos, se constata que la intervención disminuyó significativamente el nivel de estrés en los profesionales; se logró aun identificar los estresores mentales de los profesionales por medio de la Escala de Estrés en Profesionales.

ABSTRACT Objective: To compare the levels of ex-post-facto stress between nursing personnel who participated in an educational intervention with nursing personnel on work duties, within the hospital work environment. Materials and method: This was an observational and cross-sectional study. The final sample was composed of 30 nursing personnel, with 15 of them composing the group exposed to the intervention and 15 being selected by simple random sampling to compose the unexposed group. The intervention consisted of a program focused on the employees, structured in four sessions, applied in a course format twice a week, and lasted two months. The Student's t-test for independent samples and the Mann-Whitney U-test were used to compare the groups. Results: Using the Mann-Whitney U-test, the stress levels could be compared between the groups, and a statistical difference in stress levels was observed between the control group (3.34 ± 0.71 a.u.) and the intervention group (2.52 ± 0.59 a.u.) (p = 0.002; d = 1.26). Conclusions: Comparing the general stress levels between the groups, it was found that the intervention significantly decreased the stress levels in the participants; it was also possible to identify the mental stressors faced by the participants using the Scale of Stress in Professionals.

RESUMO Objetivo: comparar os níveis de estresse ex-post-fact entre os profissionais de enfermagem no ambiente do trabalho hospitalar participantes de intervenção educativa com profissionais de enfermagem em atividades laborais. Materiais e método: estudo observacional e transversal. A amostra final foi composta por 30 profissionais de enfermagem, da qual 15 profissionais compuseram o grupo exposto à intervenção e 15 foram selecionados por amostragem aleatória simples para compor o grupo não exposto. A intervenção consistiu em um programa, com foco no trabalhador, estruturado em quatro sessões, aplicado em formato de curso, com periodicidade quinzenal e duração de dois meses. Na comparação entre os grupos, foram utilizados o teste t de Student para amostras independentes e o teste U de Mann-Whitney. Resultados: por meio do teste U de Mann-Whitney, pode-se comparar o nível de estresse entre os grupos, no qual se observou diferença estatística do nível de estresse entre o grupo controle (3,34 ± 0,71 u.a.) e o grupo intervenção (2,52 ± 0,59 u.a.) (p = 0,002; d = 1,26). Conclusões: comparando o nível de estresse geral entre os grupos, constata-se que a intervenção diminuiu significativamente o nível de estresse nos profissionais; foi possível ainda identificar os estressores mentais dos profissionais por meio da Escala de Estresse em Profissionais.
