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.

Knowledge, attitudes and practices of community health agents regarding pulmonary tuberculosis in a capital city in northeastern Brazil. / Conhecimento, atitudes e práticas de agentes comunitários de saúde sobre tuberculose pulmonar em uma capital do Nordeste do Brasil.

This article analyses the knowledge, attitudes and practices of community health agents (CHAs) regarding tuberculosis in Recife, a municipality with a high incidence of tuberculosis and high treatment dropout rates in Brazil. The cross-sectional study was conducted with a representative sample of CHAs and a standardized questionnaire. The frequencies of the variables related to knowledge, attitudes and practices were described, and the association between satisfactory knowledge and appropriate practices of CHAs was analysed. Of the 401 eligible CHAs, 385 (96.0%) were interviewed. The majority were women (87.5%) aged ≥ 40 years (66.0%) and had been on the job for more than nine years (74.5%). A large percentage (61.7%) had satisfactory knowledge about tuberculosis, and this knowledge (75.8%) was associated with appropriate practices (p = 0.008). Regarding attitudes, 97.1% of CHAs were believed to be at risk of contracting tuberculosis, and 53.2% attributed this risk to their job. The results suggest the need for investment in training actions that may help improve tuberculosis indicators in the municipality.

Esse artigo analisa o conhecimento, atitudes e práticas sobre tuberculose de agentes comunitários de saúde (ACS) no Recife, município com altas taxas de incidência e de abandono do tratamento no Brasil. O estudo transversal foi conduzido em uma amostra representativa dos ACS utilizando questionário padronizado. Descreveram-se as frequências das variáveis referentes ao conhecimento, atitudes e práticas e analisou-se a associação do conhecimento satisfatório e práticas adequadas com características dos ACS. Dos 401 ACS elegíveis, 385 (96,0%) foram entrevistados. A maioria era composta por mulheres (87,5%), com idade ≥ 40 anos (66,0%) e desempenhando a função há mais de nove anos (74,5%). Um percentual de 61,7% tinha conhecimento satisfatório e esse conhecimento (75,8%) esteve associado às práticas adequadas (p = 0,008). Quanto às atitudes, 97,1% dos ACS acreditavam estar sob risco de contrair tuberculose e 53,2% atribuíram o risco à função. Parcela significativa dos ACS apresentou conhecimento satisfatório sobre tuberculose e esse conhecimento esteve associado às práticas adequadas. Esse resultado sugere a necessidade de investimentos em ações de capacitação que podem contribuir para a melhoria dos indicadores de tuberculose no município.
