We aimed to explore sex differences in acute treatment modalities and time metrics of patients with acute ischemic stroke (AIS) in a real-world setting. Second, we examined whether functional outcomes differed by sex and whether this was influenced by treatment timing.</p><p><strong>Methods: </strong>We analyzed data from the Dutch Acute Stroke Audit, a prospective consecutive registry of AIS patients from 72 hospitals in the Netherlands, between 2017 and 2020. We captured data on type of treatment administered (intravenous thrombolysis [IVT] and endovascular thrombectomy [EVT]), time metrics (onset-to-door time [OTDT], door-to-needle and door-to-groin times), and functional outcomes at 3 months (modified Rankin scale [mRS]). The association between sex and poor outcome (mRS 3-6) was assessed with Cox proportional hazard models stratified by type of treatment and adjusted for age, additionally for National Institutes of Health Stroke Scale (NIHSS) and OTDT.</p><p><strong>Results: </strong>Of the 58,632 patients, 26,941 (46%) were women. Compared with men, women were older (mean age 74.6 vs. 71.0, p &lt; 0.001) and presented with slightly higher NIHSS scores (median 3 [IQR 2-7] vs. 3 [IQR 1-6], p &lt; 0.001). Treatment modalities distribution (no treatment, IVT, EVT) was similar between women and men (64; 29; 10 vs. 63; 30; 9%, p = 0.16). Women had a slightly longer OTDT (median 145 vs. 139 min, p &lt; 0.01). Women had increased odds of poor outcomes (OR 1.49 [95% CI: 1.43-1.56]). This was still statistically significant after adjusting for age and NIHSS score (OR 1.22 [95% CI: 1.16-1.28]). Neither treatment modality nor OTDT had an additional influence on this association.</p><p><strong>Conclusion: </strong>In this large real-world registry, we observed no differences in distribution of treatment modalities between sexes. We did find a minor pre-hospital delay in women and worse functional outcomes in women. The minor delay in OTDT does not fully explain the observed worse outcomes in women. Our results provide reassurance that no major sex biases are apparent in acute stroke management throughout participating Dutch centers.</p>","PeriodicalId":9683,"journal":{"name":"Cerebrovascular Diseases","volume":" ","pages":"1-7"},"PeriodicalIF":2.2,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141554224","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
