RESUMEN
INTRODUCTION: The health system is one of the professional sectors perhaps most at risk of occupational asthma. The aims of this study were to evaluate the level of knowledge of health care workers (HCWs) on occupational asthma and asthmogenic agents and to pave the way to effective educational action on the subject. METHODS: A multicenter transversal study including 180 HCWs was carried out between July and December 2020. A validated questionnaire addressed four dimensions: knowledge of asthmatic disease, knowledge of occupational asthma, knowledge of prognosis of occupational asthma and knowledge on the prevention of occupational asthma. RESULTS: The average total score was 13.71/18 (76.17%). There was no correlation between average total score and age, educational level, seniority or status of paramedical staff. Mean total scores were significantly higher for participants with no fixed work schedule and those practicing in non-university structures. The difficulty indexes for the four aforementioned dimensions were 82.22%, 77.56%, 53.52% and 66.67% respectively. CONCLUSIONS: Knowledge gaps affect all professional categories but to different degrees. A review of the level of knowledge of persons in each category would be the first step on the road to planned educational action.
RESUMEN
BACKGROUND: The aim of this study was to retrospectively describe the evolution of symptoms, infections, and mortality at a nursing facility in France that had implemented a protocol for the prevention and treatment of COVID-19. METHODS: A database was created on 21 March 2020 to store all information related to residents, including co-morbidities, as well as COVID-19 symptoms, incidence, and mortality. Residents followed a COVID-19 protocol, consisting of preventive (administering vitamins and zinc, social distancing, and temperature checks) and active (antibiotics, anticoagulants, and corticosteroids) measures. RT-PCR and serology testing were performed on residents. A new coefficient, named the Zemgor coefficient, was calculated as the haemoglobin-to-albumin ratio at 2 time points 15 days apart, to monitor hypoxemia. RESULTS: In January 2020, the nursing facility housed 192 residents, 75 men and 117 women, aged 80±11. One or more co-morbidities were present in 94% of residents, with the most common being dementia. The COVID-19 protocol provided 61% of residents with anticoagulants, 51%with antibiotics, 21% with oxygen therapy, and 3% with corticosteroids. The COVID-19 incidence was 51% based on presence of COVID-19 symptoms, 35% based on positive RT-PCR (amongst residents tested for RT-PCR) and 41% based on positive serology (amongst residents tested for serology), and the COVID-19 mortality rate was 8%. The Zemgor coefficient was 0.049±0.053 for patients with hypoxemia compared to 0.011±0.041 for patients without hypoxemia (P=0.001). CONCLUSIONS: The protocol for the prevention and treatment of COVID-19 implemented at this nursing facility resulted in a COVID-19 incidence and mortality at the lower end of that reported by other nursing facilities.
