[Effect of the COVID-19 pandemic and preventive social isolation measures on the number of outpatient visits, hospitalizations and treatment of cerebrovascular accident in a neurological center in Argentina].

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.
