Author Response: Novel Score for Stratifying Risk of Critical Care Needs in Patients With Intracerebral Hemorrhage

We thank Patel et al.1 for their interest in our study2 and congratulate them on theirs. However, we disagree with their assertions. We excluded intracerebral hemorrhage (ICH) patients with known or presumed trauma, brain mass(es) or cancer, or vascular malformations around the ICH. These patients may have critical care needs specific to the underlying condition, independent of the hemorrhage. They might also undergo semielective neurosurgical interventions to address the ICH etiology. The use of CT angiograms to identify arteriovenous malformations supports the notion that most ICHs can be correctly classified as primary vs secondary at presentation by history and imaging. We agree with Patel et al.1 to include only information available at presentation; notably, their score contains previous antiplatelet use, which is commonly unknown or uncertain at presentation.3
