Item type:Publication, Patient centered outcomes in stroke: utility-weighted modified Rankin Scale results in a community-based study(Frontiers Media SA, 2025-03-21); ; 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 &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> &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&gt;5 (<jats:italic>β</jats:italic> −0.015 [SE 0.002], <jats:italic>p</jats:italic> &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 &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.<Scopus© Citations 1 6 - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Clinical Profile of Stroke Chameleons Receiving Intravenous Thrombolysis: Insights from a Single-Center Experience(S. Karger AG, 2024-11-13); ; ; ; Eloy Mansilla<jats:p>Introduction: In emergency rooms (ERs), 5% of patients experiencing an acute ischemic stroke (AIS) receive an alternative diagnosis; these cases are known as stroke chameleons (SC). The percentage of SC treated with intravenous thrombolysis (IVT) and the characteristics have not been well described. We aimed at investigating the variables associated with the probability receiving IVT. Methods: In this prospective study, we included consecutive patients with SC admitted at the ER of Clínica Alemana between September 2014 and October 2023. Results: Among 1,193 stroke patients; sixty-three (5.2%) corresponded to SC. Ten of these cases (15.8%, 95% CI: 8.8–26.8) were treated with IVT, mean door-to-needle (DTN) time of 85.7 (SD 35) min, median of 73.5 (IQR 62–113) min. SCs who underwent IVT were younger (p = 0.01), with higher NIHSS (p = 0.05). They presented more frequently with altered level of consciousness in the NIHSS (p = 0.01), language abnormities (p = 0.001), and dysarthria (p = 0.01). In multivariate analysis, none of the variables were significantly associated with IVT. A secondary analysis showed that only time to brain imaging was significantly associated with IVT (OR: 0.99; 95% CI: 0.98–0.99; p = 0.01). Conclusions: Almost 1 out of every 7 SC could be treated with IVT but with a prolonged DTN time; the chance of being treated is associated with time to brain imaging. <p>Introduction: In emergency rooms (ERs), 5% of patients experiencing an acute ischemic stroke (AIS) receive an alternative diagnosis; these cases are known as stroke chameleons (SC).
