RESUMO
INTRODUCTION: It has been proposed that exposure to pulmonary function tests (PFT) could be associated with a higher risk of viral transmission. The risk of the Coronavirus Disease 2019 (COVID-19) transmission after performing PFT is unknown. We aimed to assess the incidence of COVID-19 after a PFT at an academic teaching facility in Buenos Aires, Argentina. MATERIALS AND METHODS: We conducted a retrospective cohort study including all consecutive adult patients that performed PFT between April 1, 2020 and September 30, 2020. Patients with prior COVID-19 were excluded. We defined a 15-day time window to ascertain PFT related COVID-19. The primary outcome was ascertained by consulting a national database, which has information on all patients with nasopharyngeal swabs for SARS-CoV-2 in Argentina. RESULTS: We included 278 patients who performed a PFT. Fifty percent were women, the mean age was 54 years (SD 18), and the main comorbidities were obesity (31%), smoking (31%), hypertension (29%), and chronic lung disease (28%). The main indication for performing PFT was anesthetic preoperative risk assessment. Swabs were collected from 27 patients (10%). Twenty-two swabs (8%) were taken according to surgical protocols; five swabs (2%) were taken due to clinical suspicion of COVID-19, with only one testing positive. The cumulative incidence of COVID-19 after PFT was 0.36% (95% CI 0.01-20%). None of the technicians developed symptomatic disease. CONCLUSION: Given the right setting and strict adherence to international recommendations, the SARS-CoV-2 infection after having a PFT appears to be low, which follows that these procedures can be performed safely for both patients and staff.
Introducción: Se ha propuesto que las pruebas de función respiratorias (PFR) podrían estar asociadas con un mayor riesgo de transmisión viral. El riesgo de presentar la enfermedad por coronavirus 2019 (COVID-19) después de realizar una PFR es desconocido. El objetivo del estudio fue estimar la incidencia de COVID-19 después de llevar a cabo una PFR, en un Hospital Universitario de la ciudad Autónoma de Buenos Aires, Argentina. Se realizó una cohorte retrospectiva que incluyó a todos los pacientes que realizaron una PFR entre el 1 de abril de 2020 y el 30 de septiembre de 2020. Se excluyeron los pacientes con antecedentes de COVID-19. Definimos una ventana de tiempo de 15 días para determinar la presencia de COVID-19 relacionada con la realización de la PFR. El resultado primario se determinó consultando una base de datos nacional, que contiene información sobre todos los pacientes que se han realizado hisopados nasofaríngeos para detección del SARS-CoV-2 en Argentina. Materiales y métodos: Se incluyeron 278 pacientes, el 50% fueron mujeres, el promedio de edad fue de 54 años (DE 18) y las principales comorbilidades fueron: obesidad (31%), tabaquismo (31%), hipertensión (29%) y enfermedades respiratorias crónicas (28%). La principal indicación de la PFR fue la evaluación pre operatoria o anestésica. A 27 pacientes (10%) se les realizó un hisopado nasofaríngeo para búsqueda de SARS-CoV-2. Veintidós hisopados (8%) se solicitaron por evaluación pre quirúrgica, cinco hisopados (2%) por sospecha clínica de infección y solamente uno fue positivo. La incidencia de COVID-19 fue de 0.36% (IC95% 0.01-20%). Durante el período del estudio ninguno de los operadores que realizaron las PFR presentaron síntomas compatibles con COVID-19. Conclusión: Siguiendo las recomendaciones internacionales, la frecuencia de detección de COVID-19 después de las PFR parece ser bajo, por lo que estos procedimientos se podrían llevar a cabo de forma segura tanto para los pacientes como para el personal.

BACKGROUND: Crowding in Emergency Departments (ED), results from the imbalance between the simultaneous demand for health care and the ability of the system to respond. The NEDOCS scale (National Emergency Department Crowding Scale) measures the degree of crowding in an ED. AIM: To describe ED Crowding characteristics, using the NEDOCS scale, in an Argentinean hospital. MATERIAL AND METHODS: A retrospective cohort study was conducted with all adult patient consultations between July 2013 and July 2014 at the ED of Hospital Italiano de Buenos Aires. We included all hours in the analysis period (365 days x 24 h = 8,760). The NEDOCS value was calculated for each hour using an automatic algorithm and was quantified in a six points score. Levels 4 (overcrowded), 5 (severely overcrowded) and 6 (dangerously overcrowded) were defined as overcrowding. Contour plots analysis was applied to identify patterns. RESULTS: During the study period, 124,758 visits to the ED were registered. Overcrowding was present in 57.7% (5,055) of the analyzed hours. A predominance of scores between four and five was observed between 10:00 and 24:00 hours. The months with predominance of overcrowding were June, July and August (southern winter). CONCLUSIONS: The calculation of the NEDOCS score and the analysis of its temporal distribution are highly relevant to identify opportunities for improvement and to develop mechanisms to prevent the highest categories of overcrowding.
