Observational Study
Temporal Trends in Emergency Medical Services and General Practitioner Use for Acute Stroke After Australian Public Education Campaigns.
Background and Purpose- The Australian Stroke Foundation ran annual paid advertising between 2004 and 2014, using the FAST (Face, Arm, Speech, Time) campaign from 2006 and adding the message to call emergency medical services in 2007. In this study, we examined temporal trends in emergency medical services use and referrals from general practitioners in the Australian state of Victoria to evaluate the impact of these campaigns. Methods- Using data from 33 public emergency departments, contributing to the Victorian Emergency Minimum Dataset, we examined trends in emergency department presentations for 118 000 adults with an emergency diagnosis of stroke or transient ischemic attack between 2003 and 2015. ⋯ Results- Compared with the precampaign period, significant increases in emergency medical services use were seen annually between 2008 and 2015 (all P<0.001, eg, 2015; adjusted odds ratio, 1.16; 95% CI, 1.10-1.23). In contrast, a decrease was seen in patients presenting via general practitioners across all campaign years (all P<0.001, eg, 2015; adjusted odds ratio, 0.48; 95% CI, 0.44-0.53). Conclusions- Since the Stroke Foundation campaigns began, a greater proportion of stroke and transient ischemic attack patients are presenting to hospital by emergency medical services and appear to be bypassing their general practitioners.

Background and Purpose—Commonly used tools to determine functional outcome after aneurysmal subarachnoid hemorrhage (aSAH) have limitations. Time spent at the patient’s home has previously been proposed as a robust outcome measure after ischemic stroke. Here, we set out to validate home-time as an outcome measure after aSAH. Methods—We examined prospectively collected data from a nationwide multicenter registry of aSAH patients admitted to a tertiary neurosurgical department in Switzerland (Swiss SOS [Swiss Study on Aneurysmal Subarachnoid Hemorrhage]; 2009–2015). ⋯ Increasing home-time was associated with improved modified Rankin Scale scores at time of hospital discharge (P<0.0001) and at 1-year follow-up (P<0.0001). Within each of the 8 participating hospitals, the relationship between home-time and modified Rankin Scale was maintained. Conclusions—Home-time for the first 90 days after aSAH offers a robust and easily ascertainable outcome measure, discriminating particularly well across better recovery levels at time of hospital discharge and at 1-year follow-up. This measure complies with the modern trend of patient-centered healthcare and research, representing an outcome that is particularly relevant to the patient.

Randomized Controlled Trial Multicenter Study
Vagus Nerve Stimulation Paired With Upper Limb Rehabilitation After Chronic Stroke.
Background and Purpose- We assessed safety, feasibility, and potential effects of vagus nerve stimulation (VNS) paired with rehabilitation for improving arm function after chronic stroke. Methods- We performed a randomized, multisite, double-blinded, sham-controlled pilot study. All participants were implanted with a VNS device and received 6-week in-clinic rehabilitation followed by a home exercise program. ⋯ A pivotal study of this therapy is justified. Clinical Trial Registration- URL: https://www.clinicaltrials.gov. Unique identifier: NCT02243020.

Background and Purpose- Minimally invasive surgery (MIS) for intracerebral hemorrhage (ICH) has been evaluated in numerous clinical trials. Although meta-analyses for this strategy have been performed in the past, recent trials add important information to results of the comparison and permit strategy-specific analyses, including evaluation of endoscopic evacuation and stereotactic thrombolysis. Methods- Major scientific databases including but not limited to Pubmed, the CENTRAL (Cochrane Central Register of Controlled Trials), Embase, Web of Science, Scopus, the ICTRP (International Clinical Trials Registry Platform), the Internet Stroke Center, and the CNKI (Chinese National Knowledge Infrastructure) were searched in October of 2017 for randomized controlled trials of MIS treatment of supratentorial spontaneous ICH. ⋯ We also conducted subgroup analyses focusing on time to evacuation for MIS versus conventional treatment and found 0.36 (0.22-0.59) and 0.59 (0.34-1.00) for evacuations performed within 24 hours and 0.49 (0.38-0.63) and 0.57 (0.43-0.76) for evacuations performed within 72 hours. Conclusions- This meta-analysis demonstrates that select patients with supratentorial ICH benefit from MIS over other treatments. This beneficial effect remains true when analyzing specific techniques and evacuation timing subgroups.

Background and Purpose- Transthoracic echocardiography (TTE) is widely used in the ischemic stroke setting. In this study, we aim to investigate the yield of TTE in patients with ischemic stroke and known subtype and whether the admission troponin level improves the yield of TTE. Methods- Data were abstracted from a single-center prospective ischemic stroke database for 18 months and included all patients with ischemic stroke whose etiologic subtype could be obtained without the need of TTE. ⋯ In multivariable models, there was an association between TTE changing management and positive serum troponin level (adjusted odds ratio, 4.26; 95% CI, 2.17-8.34; P<0.001). Conclusions- In patients with ischemic stroke, TTE might lead to a change in clinical management in ≈1 of 10 patients with known stroke subtype before TTE but changed acute treatment decisions in <1 percent of patients. Serum troponin levels improved the yield of TTE in these patients.
