    Background and aims</jats:title><jats:p>The transformation of modified Rankin Scale (mRS) scores based on the corresponding utilities of health-related quality of life questionnaires can facilitate the capture of Patient-Centered Outcomes (PCO) in stroke. We aimed to derive utility-weighted modified Rankin Scale (UW-mRS) values by mapping mRS functional status to EQ-5D-3L scores in a population-based cohort of stroke patients.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>The UW-mRS was obtained by analyzing the EQ5-D-3 L and mRS scores at 180 days after any stroke in the ÑANDU study, a large prospective community-based study in Chile. The mRS prediction was estimated using a linear regression adjusted by the EQ-5D-3L value. Generalized linear and binary logistic regression models were constructed to determine influencing factors of the UW-mRS, using STATA software (version 18.0).</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>We included 773 patients presenting with any stroke during 2015–2016: 48% were female, with a mean age of 71 years (SD 13.8), and 85% had an acute ischemic stroke (AIS). 82% of patients had a low socioeconomic status, 50% had less than 12 years of formal education, and only 32% lived in urban areas. UW-mRS values for mRS categories 0–6 at 180 days were 0.913, 0.694, 0.425, 0.249, −0.102, −0.347 and 0, respectively. Multivariable analysis identified age &amp;gt; 70 years (Coefficient <jats:italic>β</jats:italic> [β] -0.038 [Standard error SE 0.018], <jats:italic>p</jats:italic> = 0.032), prior mRS score 3–5 (<jats:italic>β</jats:italic> −0.556 [SE 0.197], <jats:italic>p</jats:italic> &amp;lt; 0.001), ischemic stroke (β −0.066 [SE 0.025], <jats:italic>p</jats:italic> = 0.010), and National Institutes of Health Stroke Scale (NIHSS) at admission&amp;gt;5 (<jats:italic>β</jats:italic> −0.015 [SE 0.002], <jats:italic>p</jats:italic> &amp;lt; 0.001) as significant predictors of worse UW-mRS scores (R<jats:sup>2</jats:sup> = 70%) in the overall group. Sex-disaggregated analysis showed that age &amp;gt; 70 years was a significant predictor in males (β −0.069 [SE 0.024], <jats:italic>p</jats:italic> = 0.006), while presenting an AIS had a greater impact on female’s worse UW-mRS score (β −0.087 [SE 0.033], <jats:italic>p</jats:italic> = 0.010).</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>These results present UW-mRS values derived from a population-based stroke study. Key determinants of health-related quality of life in post-stroke patients included age, prior disability, and stroke severity. Sex-disaggregated analysis revealed age being significant for males and AIS for females. Incorporating PCO as UW-mRS in stroke research can provide a more nuanced understanding of the impact of stroke on survivors, offering valuable insights for clinical decision-making and rehabilitation strategies across diverse healthcare contexts.<

    <jats:sec><jats:title>Background</jats:title><jats:p>During the COVID-19 pandemic, decreased volumes of stroke admissions and mechanical thrombectomy were reported. The study’s objective was to examine whether subarachnoid haemorrhage (SAH) hospitalisations and ruptured aneurysm coiling interventions demonstrated similar declines.</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>We conducted a cross-sectional, retrospective, observational study across 6 continents, 37 countries and 140 comprehensive stroke centres. Patients with the diagnosis of SAH, aneurysmal SAH, ruptured aneurysm coiling interventions and COVID-19 were identified by prospective aneurysm databases or by International Classification of Diseases, 10th Revision, codes. The 3-month cumulative volume, monthly volumes for SAH hospitalisations and ruptured aneurysm coiling procedures were compared for the period before (1 year and immediately before) and during the pandemic, defined as 1 March–31 May 2020. The prior 1-year control period (1 March–31 May 2019) was obtained to account for seasonal variation.</jats:p></jats:sec><jats:sec><jats:title>Findings</jats:title><jats:p>There was a significant decline in SAH hospitalisations, with 2044 admissions in the 3 months immediately before and 1585 admissions during the pandemic, representing a relative decline of 22.5% (95% CI −24.3% to −20.7%, p&lt;0.0001). Embolisation of ruptured aneurysms declined with 1170–1035 procedures, respectively, representing an 11.5% (95%CI −13.5% to −9.8%, p=0.002) relative drop. Subgroup analysis was noted for aneurysmal SAH hospitalisation decline from 834 to 626 hospitalisations, a 24.9% relative decline (95% CI −28.0% to −22.1%, p&lt;0.0001). A relative increase in ruptured aneurysm coiling was noted in low coiling volume hospitals of 41.1% (95% CI 32.3% to 50.6%, p=0.008) despite a decrease in SAH admissions in this tertile.</jats:p></jats:sec><jats:sec><jats:title>Interpretation</jats:title><jats:p>There was a relative decrease in the volume of SAH hospitalisations, aneurysmal SAH hospitalisations and ruptured aneurysm embolisations during the COVID-19 pandemic. These findings in SAH are consistent with a decrease in other emergencies, such as stroke and myocardial infarction.</jats:p></jats:sec>

    <jats:sec> <jats:title>Background and Purpose—</jats:title> <jats:p>Standardized registries may provide valuable data to further improve stroke care. Our aim was to obtain updated information about characteristics of stroke patients and management of stroke across the Ibero-American countries, using a common in-hospital registry (Safe Implementation of Treatments in Stroke–Sociedad Iberoamericana de Enfermedades Cerebrovasculares) as a basis for further quality improvement.</jats:p> </jats:sec> <jats:sec> <jats:title>Methods—</jats:title> <jats:p>Data for this study were entered into the Safe Implementation of Treatments in Stroke registry from September 2009 to December 2013 by 58 centers in 14 countries. Data included demographics, risk factors, onset-to-door time, National Institutes of Health Stroke Scale score, stroke subtype, ischemic stroke etiology, treatments, 3-month mortality, and modified Rankin Scale score. Time to treatment was also recorded for patients treated with thrombolysis.</jats:p> </jats:sec> <jats:sec> <jats:title>Results—</jats:title> <jats:p>Five thousand four hundred one patients were registered; median age, 65 years; 46% women; 3915 (72.5%) ischemic strokes; 686 (13.7%) hemorrhagic strokes; 213 (4.3%) subarachnoid hemorrhages; 414 (8.3%) transient ischemic attacks; and 31 (0.6%) cerebral vein thrombosis. The most prevalent risk factors were hypertension (71.3%), dyslipidemia (35.2%), and diabetes mellitus (23.6%). Atrial fibrillation was present in 15.1%. Three hundred one ischemic strokes were treated with intravenous thrombolysis (IVT; 7.7%). Patients undergoing IVT were more severely affected (median baseline National Institutes of Health Stroke Scale score, 11 versus 6). The rate of symptomatic intracerebral hemorrhages after IVT was 5.7%. At 3 months, 60.3% of IVT-treated patients and 59.1% of untreated patients were independent (modified Rankin Scale score, 0–2). Mortality was 11.4% in treated and 12.8% in untreated patients.</jats:p> </jats:sec> <jats:sec> <jats:title>Conclusions—</jats:title> <jats:p>Safe Implementation of Treatments in Stroke–Sociedad Iberoamericana de Enfermedades Cerebrovasculares is the largest registry of a general stroke population and the first study to evaluate the level of IVT use in Ibero-America. It provides valuable information that may help to improve the quality of stroke care in the Ibero-American region.</jats:p> </jats:sec>
