Urgent treatment of acute stroke in rural Australia is problematic partly because of limited access to medical specialists. Utilization of telemedicine could improve delivery of acute stroke treatments in rural communities. ⋯ This research will provide evidence for an effective telestroke program for use in regional Australian hospitals.

A large diffusion-weighted imaging lesion ≤six-hours of symptom onset was found to predict the development of 'malignant' middle cerebral artery infarction with high specificity, positive predictive value, and negative predictive value, but sensitivity was low. ⋯ Clinical follow-up examination after 24 h helps identify patients at risk of 'malignant' middle cerebral artery infarction that are missed by predictive algorithms based on early diffusion-weighted imaging lesion volume alone.

The cause of perimesencephalic hemorrhage is unknown, but a venous source is suggested. If perimesencephalic hemorrhage is of venous origin, less elevation of the intracranial pressure and less perfusion deficits are expected than after aneurysmal subarachnoid hemorrhage. ⋯ Perimesencephalic hemorrhage patients have a higher cerebral blood flow than aneurysmal subarachnoid hemorrhage patients. The findings of this study further support a venous origin of bleeding in perimesencephalic hemorrhage patients. Future studies should further elaborate on cerebral blood flow in posterior circulation aneurysms.

Do-not-resuscitate orders may be associated with poor outcome in patients with intracerebral hemorrhage because of less active management. ⋯ In addition to confirming the role of known intracerebral hemorrhage prognostic factors in do-not-resuscitate decision-making, our results demonstrate that do-not-resuscitate orders led to less active care of intracerebral hemorrhage patients.

Fever, hyperglycemia, and swallow dysfunction poststroke are associated with significantly worse outcomes. We report treatment and monitoring practices for these three items from a cohort of acute stroke patients prior to randomization in the Quality in Acute Stroke Care trial. ⋯ Our results showed that acute stroke patients were: undermonitored and undertreated for fever and hyperglycemia; and underscreened for swallowing dysfunction and unnecessarily reassessed by a speech pathologist, indicating the need for urgent behavior change.
