RESUMO
Background and Objectives: In preparation for the suspected influx of COVID-19 patients, many healthcare systems reduced or discontinued provision of "non-urgent" care. This decision had potential impact on stroke prevention and management. We conducted a large population survey to assess the effect of mandatory social isolation on routine health controls, emergency consultations and other stroke care-related behaviors of the population during the pandemic. Methods: We distributed multiple-choice anonymous questionnaires through the institutional email database and through the email database of clients of a beverage delivery company. Most respondents resided in the metropolitan area of Buenos Aires. This is the area where the infection rates were highest and restriction measures were hardest. The survey assessed demographic characteristics and actual and potential behaviors of people regarding medical checkups, risk factors control, medication provision and response to onset of symptoms consistent with stroke or TIA. Surveys were sent during May 2020, the strictest period of the quarantine in Argentina. Results: A total of 10,303 questionnaires were completed. Thirty-seven percent of the respondents were older than 60 years, 74% were women and 16% lived alone. Vascular risk factors were present in 39% of the individuals. Seventy-six percent did not continue with their regular medical checkups during the mandatory social and preventive isolation, 21% had difficulty obtaining medical prescriptions and only 38% considered that health institutions had implemented reliable safety measures to avoid exposure to COVID-19. When asked about response in case of onset of stroke symptoms, 9% would not consult given the context of the pandemic. Six percent reported having had symptoms consistent with stroke or TIA but only 35% went to a hospital. The vast majority of the respondents said they were awaiting for the end of the quarantine to resume their usual medical care. Conclusions: The implementation of a quarantine may have some serious adverse effects on the prevention, diagnosis and treatment of stroke. These undesirable aspects should be taken into consideration in the planning, communication and implementation of health policies.
RESUMO
Resumen La fibrinólisis intravenosa con activador del plasminógeno tisular recombinante (rTPA) y la utilización de unidades cerradas, demostraron disminuir sustancialmente la morbimortalidad en pacientes con accidente cerebrovascular isquémico (ACVi). Sin embargo, los datos publicados en Argentina son escasos. Describimos la experiencia en la utilización de fibrinólisis en pacientes con ACVi agudo antes y después de la implementación de una unidad cerebrovascular (UCV) en un Centro Integral de Neurología Vascular de la Ciudad de Buenos Aires durante 17 años. Se realizó un análisis retrospectivo de pacientes consecutivos tratados con rTPA entre enero 2003 y diciembre 2019. Se evaluaron tiempos de tratamiento, de internación, complicaciones post tratamiento y discapacidad a 3 meses. Para su análisis se evaluaron los períodos pre y post apertura de la UCV, período 1 (P1 de 2003-2011) y P2 (2012 -2019). Se realizó fibrinolisis intravenosa en 182 pacientes. La apertura de UCV resultó en aumento del porcentaje de fibrinólisis sobre el total de los ACVi ingresados (4% en P1 vs. 10% en P2, p < 0.001), acortamiento del tiempo puerta-aguja (75 minutos en P1 vs. 53 minutos en P2, p < 0.00001) y mayor proporción de pacientes tratados dentro de los 60 minutos del ingreso hospitalario (36% en P1 vs. 76% en P2, p < 0.00001). Además, hubo reducción de la mediana de internación de 9 días en P1 a 5 días en P2 (p < 0.00001). En conclusión, la UCV parece optimizar la utilización de fibrinólisis en el ACVi agudo, aumentando el porcentaje de pacientes tratados, reduciendo el tiempo puerta-aguja y disminuyendo el de internación.
Abstract Intravenous fibrinolysis with recombinant tissue plasminogen activator (rTPA) and use of stroke units improve morbidity and mortality in patients with acute ischemic stroke (AIS). However, data published in Argentina are scarce. We describe the experience in the use of fibrinolysis in patients with acute ischemic stroke (AIS) before and after the implementation of a stroke unit in a Comprehensive Stroke Center in Buenos Aires during the last 17 years. Retrospective analysis of consecutive patients treated with rTPA between January 2003 and December 2019. Treatment times, hospitalization time, post-treatment complications and disability at 3 months were evaluated. For the analysis, the pre and post opening periods of the stroke unit were evaluated, Period 1 (P1, from 2003 to 2011) and Period 2 (P2, from 2012 to 2019). Intravenous fibrinolysis was performed in 182 patients. Opening of the stroke unit resulted in an increase in the percentage of fibrinolysis over the total number of admitted strokes (4% in P1 vs. 10% in P2, p < 0.001), shortening of the door-to-needle time (75 minutes in P1 vs. 53 minutes in P2, p < 0.00001) and higher proportion of patients treated within 60 minutes of hospital admission (36% in P1 vs. 76% in P2, p < 0.00001). In addition, there was a reduction in the median hospital stay from 9 days in P1 to 5 days in P2 (p < 0.00001). In conclusion, stroke units seem to optimize the use of fibrinolysis in acute stroke, increasing the percentage of patients treated, reducing door-to-needle time, and reducing hospitalization time.

Resumen La pandemia por COVID-19 y el aislamiento social preventivo y obligatorio (ASPO) han generado cambios en la organización y utilización del sistema de salud en todo el mundo. Analizamos el impacto de la situación sanitaria en el número de consultas ambulatorias, internaciones y acceso a terapias de revascularización por enfermedad cerebrovascular. Se analizó el período desde el 1 marzo al 31 de julio de 2020. Se comparó con el mismo período de 2019. Se evaluaron total de consultas ambulatorias e internaciones, escala NIHSS (National Institute of Health Stroke Scale) al ingreso, tipo de enfermedad cerebrovascular y uso de terapias de revascularización. Ingresaron 197 pacientes con eventos cerebrovasculares agudos en 2019 y 150 pacientes en 2020. Hubo un descenso significativo en el número de internaciones por eventos isquémicos totales y accidentes isquémico transitorios en el comparativo de los 5 meses. Se vio además un aumento en trombosis venosas cerebrales y hemorragias cerebrales. El acceso a fibrinolisis intravenosa y trombectomía mecánica se mantuvo estable, pero con prolongación del tiempo puerta-aguja. Las consultas ambulatorias descendieron 67%, siendo mayor el descenso en abril y más marcado en consultas de seguimiento. El número de internaciones y de consultas ambulatorias durante el ASPO descendió sustancialmente. Esto pareciera obedecer al cumplimiento estricto de la cuarentena y no a mecanismos fisiopatológicos relacionados con el COVID-19. Debe educarse a la población sobre la necesidad del control de enfermedades crónicas y de eventos agudos y se deben garantizar medidas de seguridad en los centros de salud.
Abstract The COVID-19 pandemic and preventive and compulsory social isolation (PCSI) have generated changes in the organization and use of the health system around the world. We analyze the impact of the health situation on the number of outpatient visits, hospitalizations and access to revascularization therapy for cerebrovascular disease. The period from March 1 to July 31, 2020 was analyzed. It was compared with the same period in 2019. Total outpatient and hospital visits were evaluated, NIHSS scale (National Institute of Health Stroke Scale) upon admission, type of cerebrovascular disease and use of revascularization therapies; 197 patients with acute cerebrovascular events were admitted in 2019 and 150 patients in 2020. There was a significant decrease in the number of hospitalizations for total ischemic events and transient ischemic attacks in the comparison of 5 months. An increase in cerebral venous thrombosis and cerebral hemorrhages was also seen. Access to intravenous fibrinolysis and mechanical thrombectomy remained stable, but with prolonged door-to-needle time. Outpatient visits fell 67%, the decrease being greater in April and more marked in follow-up visits. The number of hospitalizations and outpatient visits during the PCSI dropped substantially. This seems to be due to strict compliance with quarantine and not to pathophysiological mechanisms related to COVID-19. The population should be educated about the need to control chronic diseases and acute events and safety measures should be guaranteed in health centers.
