ABSTRACT

Background: Since the beginning of the COVID-19 pandemic, health professionals have been working under extreme conditions, increasing the risk of physical and mental illness. We evaluated the prevalence of burnout and its associated factors among postgraduate student residents in health professions during the global health crisis. Methods: Healthcare residents were recruited from all across Brazil between July and September 2020 through digital forms containing instruments for assessing burnout (Oldenburg Burnout Inventory (OLBI)), resilience (brief resilient coping scale (BRCS)) and anxiety, stress and depression (depression, anxiety and stress scale (DASS-21) and Patient Health Questionnaire (PHQ-9)). Additionally, the relationships between burnout and chronic diseases, autonomy and educational adequacy in the residency programme, personal protective equipment (PPE), workload and care for patients with COVID-19 were evaluated. The chi-square test, Student’s t test, Pearson’s correlation test and logistic regression were performed. Results: A total of 1,313 participants were included: mean (standard deviation) age, 27.8 (4.4) years;female gender, 78.1%;white race, 59.3%;and physicians, 51.3%. The overall prevalence of burnout was 33.4%. The odds (odds ratio [95% confidence interval]) of burnout were higher in the presence of pre-existing diseases (1.76 [1.26–2.47]) and weekly work > 60 h (1.36 [1.03–1.79]) and were lower in the presence of high resilience (0.84 [0.81–0.88]), autonomy (0.87 [0.81–0.93]), and educational structure (0.77 [0.73–0.82]), adequate availability of PPE (0.72 [0.63–0.83]) and non-white race (0.63 [0.47–0.83]). Burnout was correlated with anxiety (r = 0.47;p < 0.05), stress (r: 0.58;p < 0.05) and depression (r: 0.65;p < 0.05). Conclusions: We observed a high prevalence of burnout among residents during the COVID-19 pandemic. Individual characteristics and conditions related to the work environment were associated with a higher or lower occurrence of the syndrome.

ABSTRACT

In this article, we discuss the physics involved in a ultraviolet-C (UV-C) radiation chamber used for disinfection of surfaces and objects, in the context of the COVID-19 pandemic. When exposed to UV-C radiation, viral RNA change its molecular structure, a process caused by a rearrangement in the nitrogenous basis, inactivating the virus, and preventing reproduction. We propose the construction of a UV-C chamber using materials that are accessible to the population, with security features. We also discuss the design process in determining the distance and exposition time needed for the appropriate UV-C dose. Theoretical correction factors are also used, in order to account for factors that make our approximations more realistic in terms of the geometry of the system. Experimentally, the lamp used for the prototype was tested, obtaining a power in UV-C range of Puv = 171µ W, after corrections. Exposition times were then defined, ranging from 20-90 minutes, considering distances from 5-36 cm from the objects to the lamp. © 2021. Sociedade Brasileira de Física. Printed in Brazil.
