    A Chilean Experience of Telestroke in a COVID-19 Pandemic Year
    <jats:p>&lt;b&gt;&lt;i&gt;Background and Purpose:&lt;/i&gt;&lt;/b&gt; Telemedicine for stroke patients’ care (telestroke [TS]) has grown notably in recent decades and may offer advantages during health crisis. Hospital admissions related to stroke have decreased globally during the COVID-19 pandemic, but scarce information is available regarding the effect of COVID-19 in TS. Using a population-based TS registry, we investigated the impact of the first year of the COVID-19 pandemic throughout our TS network in Santiago, Chile. &lt;b&gt;&lt;i&gt;Methods:&lt;/i&gt;&lt;/b&gt; Stroke codes evaluated after the onset of COVID-19 restrictions in Chile (defined as March 15, 2020) were compared with those evaluated in 2019. We analyzed differences between number of stroke codes, thrombolysis rate, stroke severity, and time from the stroke onset to hospital admission. &lt;b&gt;&lt;i&gt;Results:&lt;/i&gt;&lt;/b&gt; We observed that the number of stroke codes and the number of patients undergoing reperfusion therapy did not change significantly (&lt;i&gt;p&lt;/i&gt; = 0.669 and 0.415, respectively). No differences were found with respect to the median time from the stroke onset to admission (&lt;i&gt;p&lt;/i&gt; = 0.581) or in National Institutes of Health Stroke Scale (NIHSS) scores (&lt;i&gt;p&lt;/i&gt; = 0.055). The decision-making-to-needle time was significantly shorter in the COVID-19 period (median 5 min [IQR 3–8], &lt;i&gt;p&lt;/i&gt; &amp;#x3c; 0.016), but no significant changes were found at the other times. &lt;b&gt;&lt;i&gt;Conclusions:&lt;/i&gt;&lt;/b&gt; This study demonstrates the potential of adapting TS to extreme situations such as the COVID-19 pandemic, as well as the importance of establishing networks that facilitate patient access to quality treatments. </jats:p>

    <jats:sec><jats:title>Study Design:</jats:title><jats:p> Cross-sectional survey. </jats:p></jats:sec><jats:sec><jats:title>Objectives:</jats:title><jats:p> Assessment of subaxial cervical facet injuries using the AO Spine Subaxial Cervical Spine Injury Classification System is based on CT scan findings. However, additional radiological evaluations are not directly considered. The aim of this study is to determine situations in which spine surgeons request additional radiological exams after a facet fracture. </jats:p></jats:sec><jats:sec><jats:title>Methods:</jats:title><jats:p> A survey was sent to AO Spine members from Latin America. The evaluation considered demographic variables, routine use of the Classification, as well as the timepoint at which surgeons requested a cervical MRI, a vascular study, and/ or dynamic radiographs before treatment of facet fractures. </jats:p></jats:sec><jats:sec><jats:title>Results:</jats:title><jats:p> There was 229 participants, mean age 42.9 ± 10.2 years; 93.4% were men. Orthopedic surgeons 57.6% with 10.7 ± 8.7 years of experience in spine surgery. A total of 86% used the Classification in daily practice. An additional study (MRI/vascular study/and dynamic radiographs) was requested in 53.3%/9.6%/43.7% in F1 facet injuries; 76.0%/20.1%/50.2% in F2; 89.1%/65.1%/28.4% in F3; and 94.8%/66.4%/16.6% in F4. An additional study was frequently required: F1 72.5%, F2 86.9%, F3 94.7%, and F4 96.1%. </jats:p></jats:sec><jats:sec><jats:title>Conclusions:</jats:title><jats:p> Spine surgeons generally requested additional radiological evaluations in facet injuries, and MRI was the most common. Dynamic radiographs had a higher prevalence for F1/F2 fractures; vascular studies were more common for F3/F4 especially among surgeons with fewer years of experience. Private hospitals had a lower spine trauma cases/year and requested more MRI and more dynamic radiographs in F1/F2. Neurosurgeons had more vascular studies and dynamic radiographs than orthopedic surgeons in all facet fractures. </jats:p></jats:sec>
