Delivering cutting-edge treatments to patients is a key motivation for neurology expert Dr Neil Spratt.

More than 60,000 Australians suffer strokes each year and one-third of first-time sufferers die within a year. Clinician and stroke researcher Dr Neil Spratt maintains that such grim statistics are all the motivation he and his colleagues in the University's translational research team need in their quest to develop urgently needed new treatments. 

Spratt likes to use the case of a particular patient to illustrate the effectiveness of practice-driven research, which combines the benefits of scientific discovery and clinical observation.

"Three of our key research programs came together to ensure this patient's successful treatment," explains Spratt, a neurologist who leads the stroke translation laboratory within the School of Biomedical Sciences and Pharmacy at the University of Newcastle.

Thanks to a triage protocol instigated by the stroke research team that works across the University and the John Hunter Hospital (JHH), ambulance officers identified the 26-year-old patient as a candidate for time-critical treatment and expedited her transfer to the hospital, where Spratt was waiting in the emergency bay to assess her condition. The patient quickly underwent advanced CT perfusion imaging – a cutting-edge technique pioneered by the Newcastle research team to assess brain damage and determine a patient's suitability for clot-busting treatment. Then, she received the drug Tenecteplase (TPK) as part of a groundbreaking clinical trial – later published in the New England Journal of Medicine – that has shown it to be a more effective treatment than the standard medication, Alteplase (TPA).

From displaying poor speech and registering weakness down her whole right side on admittance, the woman was discharged three days later showing no obvious effects of the stroke. A happy ending for the patient but also, as Spratt points out, a great example of translational research in action.

"Combining clinical work with research allows us to more quickly move promising therapies from the laboratory into practice," he asserts. "We talk about the concept of 'bench to bedside' research but translational medicine is also 'bedside back to bench'. In this case we were able to see the direct results of those three research programs – the triage protocol, the CT imaging and the Tenecteplase trial – and that is very exciting and gratifying for a researcher."

Spratt, a neurology specialist at the JHH, is a key member of the Hunter Medical Research Institute (HMRI) Stroke Research Group. His team's current research into the use of body cooling to reduce the spread of brain injury in stroke victims has led to a breakthrough finding that could makethe treatment more viable for a much wider range of patients.

Cooling the body to 32-33 degrees Celsius for between 12 and 24 hours ­– effectively putting it into a state of hibernation  – can stall the progression of brain injury and buy time for a blood clot to break up. The procedure is potentially life-saving, but putting the body into a prolonged state of hypothermia can produce severe side effects, including pneumonia or disruption to heart rhythm. As well, pressure within the skull (intracranial pressure) tends to rise sharply in stroke victims within 72 hours of the incident, and while cooling will reduce this pressure, it may return or go even higher once the patient's body is warmed up again.

Spratt and colleagues Dr Damian McLeod and PhD student Lucy Murtha have discovered, through laboratory work with animal models, that if the body is cooled for just one to two hours before the pressure within the skull has risen, there is no subsequent rise in pressure after the treatment, and less likelihood of other side effects.

"There are other research groups around the world looking at body cooling as part of stroke treatment but we are the only team to have honed in on the possibility that short-period body cooling can effectively prevent intracranial pressure rising, so it is a novel and very important discovery," Spratt explains. "Elevated intracranial pressure is a problem in many other diseases, too, so our findings may well have application in medical fields outside of neurology."

Spratt's team has received more than $422,000 from the National Health and Medical Research Council (NHMRC) to further its research, which he hopes will lead to full clinical trials within three years. He also holds a three-year NHMRC-funded fellowship to continue his work in the field.

Productive partnerships

Returning to Newcastle to pursue his research career gave Dr Neil Spratt the opportunity to link with leading researchers Professor Mike Calford, now the University's Deputy Vice-Chancellor (Research), and Professor Chris Levi, director of its Priority Research Centre for Translational Neuroscience and Mental Health.

"I have great respect for both of them," Spratt states. "Both Chris and I trained at the National Stroke Research Institute (NSRI), in Melbourne, which has a very strong focus on 'bench to bedside' research, and even before coming to Newcastle I was collaborating with researchers in Mike's team of neuroscientists."

Spratt completed undergraduate studies in medicine and medical science at the University of Newcastle and undertook a PhD at the NSRI and the University of Melbourne. He returned to Newcastle in late 2006 to take up a Senior Research Fellowship sponsored by HMRI and the Greater Building Society. Spratt believes he has been fortunate to have had "wonderful mentoring" in Newcastle, nominating Calford and Levi as major influences, as well as senior neurologist Associate Professor Mark Parsons and neuroscientist Professor John Rostas.

"What has been important to my career is being part of this translational research team that works across the University of Newcastle, the hospital and HMRI. The clinical research in the hospital is world-class and is matched by the standard of scientific research.

"It is critical in my field to have that capacity to think about new ideas and collaborate with people in other disciplines. There is a culture here of hard work and high expectations and the physical proximity of the hospital and the University really facilitates those vital collaborations."

In both the human and animal literature, it has largely been assumed that edema is the primary cause of intracranial pressure (ICP) elevation after stroke and that more edema equates to higher ICP. We recently demonstrated a dramatic ICP elevation 24 hours after small ischemic strokes in rats, with minimal edema. This ICP elevation was completely prevented by short-duration moderate hypothermia soon after stroke. Here, our aims were to determine the importance of edema in ICP elevation after stroke and whether mild hypothermia could prevent the ICP rise. Experimental stroke was performed in rats. ICP was monitored and short-duration mild (35 °C) or moderate (32.5 °C) hypothermia, or normothermia (37 °C) was induced after stroke onset. Edema was measured in three studies, using wet-dry weight calculations, T 2 -weighted magnetic resonance imaging, or histology. ICP increased 24 hours after stroke onset in all normothermic animals. Short-duration mild or moderate hypothermia prevented this rise. No correlation was seen between ¿ICP and edema or infarct volumes. Calculated rates of edema growth were orders of magnitude less than normal cerebrospinal fluid production rates. These data challenge current concepts and suggest that factors other than cerebral edema are the primary cause of the ICP elevation 24 hours after stroke onset.

Background: Data highlight the importance of undertaking intense and frequent repetition of activities within stroke rehabilitation to maximise recovery. An enriched environment (EE) provides a medium in which these activities can be performed and enhanced recovery achieved. An EE has been shown to promote neuroplasticity in animal models of stroke, facilitating enhanced recovery of motor and cognitive function. However, the benefit of enriching the environment of stroke survivors remains unknown. Aim: To qualitatively explore stroke survivors' experience of implementation of exposure to an EE within a typical stroke rehabilitation setting, in order to identify facilitators and barriers to participation. Methods: Semi-structured interviews with 10 stroke survivors (7 females and 3 males, mean age of 70.5 years) exposed to an EE for a 2-week period following exposure to routine rehabilitation within a stroke rehabilitation ward. An inductive thematic approach was utilised to collect and analyse data. Results: Qualitative themes emerged concerning the environmental enrichment paradigm including: (1) "It got me moving"-perceived benefits of participation in an EE; (2) "You can be bored or you can be busy."-Attenuating factors influencing participation in an EE; (3) "I don't like to make the staff busier"-limitations to use of the EE. Conclusions: This study provides preliminary support for the implementation of an EE within a typical stroke rehabilitation setting from a patient perspective. Reported benefits included (1) increased motor, cognitive and sensory stimulation, (2) increased social interaction, (3) alleviation of degree of boredom and (4) increased feelings of personal control. However, participants also identified a number of barriers affecting implementation of the EE. We have previously published findings on perceptions of nursing staff working with stroke survivors in this enriched rehabilitation environment who identified that patients benefited from having better access to physical, cognitive and social activities. Together, results contribute to valuable evidence for future implementation of an EE in stroke rehabilitation settings.Implications for RehabilitationStroke survivor access to an enriched environment (EE):Results identified that participation in both individual and communal forms of environment enrichment within the stroke rehabilitation ward resulted in increased access to activities providing increased opportunities for enhanced motor, cognitive and sensory stimulation.Increased access to and participation in activities of the environmental enrichment (individual and communal) interrupted the ongoing cycle of boredom and inactivity experienced by many participants.This study provides preliminary support for the implementation of an EE within a typical stroke rehabilitation setting from a patient perspective.

Objective. To investigate the use of the six-minute walk test (6MWT) for stroke survivors, including adherence to 6MWT protocol guidelines and distances achieved. Methods. A systematic search was conducted from inception to March 2014. Included studies reported a baseline (intervention studies) or first instance (observational studies) measure for the 6MWT performed by stroke survivors regardless of time after stroke. Results. Of 127 studies (participants n = 6,012) that met the inclusion criteria, 64 were also suitable for meta-analysis. Only 25 studies made reference to the American Thoracic Society (ATS) standards for the 6MWT, and 28 reported using the protocol standard 30 m walkway. Thirty-nine studies modified the protocol walkway, while 60 studies did not specify the walkway used. On average, stroke survivors walked 284 ± 107 m during the 6MWT, which is substantially less than healthy age-matched individuals. The meta-analysis identified that changes to the ATS protocol walkway are associated with reductions in walking distances achieved. Conclusion. The 6MWT is now widely used in stroke studies. The distances achieved by stroke patients indicate substantially compromised walking ability. Variations to the standard 30 m walkway for the 6MWT are common and caution should be used when comparing the values achieved from studies using different walkway lengths.

Recent human imaging studies indicate that reduced blood flow through pial collateral vessels ('collateral failure') is associated with late infarct expansion despite stable arterial occlusion. The cause for 'collateral failure' is unknown. We recently showed that intracranial pressure (ICP) rises dramatically but transiently 24 hours after even minor experimental stroke. We hypothesized that ICP elevation would reduce collateral blood flow. First, we investigated the regulation of flow through collateral vessels and the penetrating arterioles arising from them during stroke reperfusion. Wistar rats were subjected to intraluminal middle cerebral artery (MCA) occlusion (MCAo). Individual pial collateral and associated penetrating arteriole blood flow was quantified using fluorescent microspheres. Baseline bidirectional flow changed to MCA-directed flow and increased by >450% immediately after MCAo. Collateral diameter changed minimally. Second, we determined the effect of ICP elevation on collateral and watershed penetrating arteriole flow. Intracranial pressure was artificially raised in stepwise increments during MCAo. The ICP increase was strongly correlated with collateral and penetrating arteriole flow reductions. Changes in collateral flow post-stroke appear to be primarily driven by the pressure drop across the collateral vessel, not vessel diameter. The ICP elevation reduces cerebral perfusion pressure and collateral flow, and is the possible explanation for 'collateral failure' in stroke-in-progression.

Background: Perfusion computed tomography is becoming more widely used as a clinical imaging tool to predict potentially salvageable tissue (ischemic penumbra) after ischemic stroke and guide reperfusion therapies. Aims: The study aims to determine whether there are important changes in perfusion computed tomography thresholds defining ischemic penumbra and infarct core over time following stroke. Methods: Permanent middle cerebral artery occlusion was performed in adult outbred Wistar rats (n=6) and serial perfusion computed tomography scans were taken every 30 mins for 2h. To define infarction thresholds at 1h and 2h post-stroke, separate groups of rats underwent 1h (n=6) and 2h (n=6) of middle cerebral artery occlusion followed by reperfusion. Infarct volumes were defined by histology at 24h. Co-registration with perfusion computed tomography maps (cerebral blood flow, cerebral blood volume, and mean transit time) permitted pixel-based analysis of thresholds defining infarction, using receiver operating characteristic curves. Results: Relative cerebral blood flow was the perfusion computed tomography parameter that most accurately predicted penumbra (area under the curve=0·698) and also infarct core (area under the curve=0·750). A relative cerebral blood flow threshold of <75% of mean contralateral cerebral blood flow most accurately predicted penumbral tissue at 0·5h (area under the curve=0·660), 1h (area under the curve=0·659), 1·5h (area under the curve=0·636), and 2h (area under the curve=0·664) after stroke onset. A relative cerebral blood flow threshold of <55% of mean contralateral most accurately predicted infarct core at 1h (area under the curve=0·765) and at 2h (area under the curve=0·689) after middle cerebral artery occlusion. Conclusions: The data provide perfusion computed tomography defined relative cerebral blood flow thresholds for infarct core and ischemic penumbra within the first two hours after experimental stroke in rats. These thresholds were shown to be stable to define the volume of infarct core and penumbra within this time window.

Rationale: No evidence-based acute therapies exist for intracerebral hemorrhage. Intracerebral hemorrhage growth is an important determinant of patient outcome. Tranexamic acid is known to reduce hemorrhage in other conditions. Aim: The study aims to test the hypothesis that intracerebral hemorrhage patients selected with computed tomography angiography contrast extravasation 'spot sign' will have lower rates of hematoma growth when treated with intravenous tranexamic acid within 4·5-hours of stroke onset compared with placebo. Design: The Spot sign and Tranexamic acid On Preventing ICH growth - AUStralasia Trial is a multicenter, prospective, 1:1 randomized, double-blind, placebo-controlled, investigator-initiated, academic Phase II trial. Intracerebral hemorrhage patients fulfilling clinical criteria (e.g. Glasgow Coma Scale >7, intracerebral hemorrhage volume <70ml, no identified secondary cause of intracerebral hemorrhage, no thrombotic events within the previous 12 months, no planned surgery) and demonstrating contrast extravasation on computed tomography angiography will receive either intravenous tranexamic acid 1g 10-min bolus followed by 1g eight-hour infusion or placebo. A second computed tomography will be performed at 24 ± 3 hours to evaluate intracerebral hemorrhage growth and patients followed up for three-months. Study outcomes: The primary outcome measure is presence of intracerebral hemorrhage growth by 24 ± 3 hours, defined as either >33% or >6ml increase from baseline, and will be adjusted for baseline intracerebral hemorrhage volume. Secondary outcome measures include growth as a continuous measure, thromboembolic events, and the three-month modified Rankin Scale score. Discussion: This is the first trial to evaluate the efficacy of tranexamic acid in intracerebral hemorrhage patients selected based on an imaging biomarker of high likelihood of hematoma growth. The trial is registered as NCT01702636. © 2013 World Stroke Organization.

Objective: To determine physical, cognitive and social activity levels of stroke patients undergoing rehabilitation, and whether these changed over time. Design: Observational study using behavioural mapping techniques to record patient activity over 12 hours on one weekday and one weekend day at baseline (week 1) and again two weeks later (week 2). Setting: A 20-bed mixed rehabilitation unit. Subjects: Fourteen stroke patients. Interventions: None. Main measures: Percentage of day spent in any activity or physical, cognitive and social activities. Level of independence using the Functional Independence Measure (FIM) and mood using the Patient Health Questionniare-9 (PHQ-9). Results: The stroke patients performed any activity for 49%, social activity for 32%, physical activity for 23% and cognitive activity for 4% of the day. Two weeks later, physical activity levels had increased by 4% (95% confidence interval (CI) 1 to 8), but levels of any activity or social and cognitive activities had not changed significantly. There was a significant: (i) positive correlation between change in physical activity and change in FIM score (r = 0.80), and (ii) negative correlation between change in social activity and change in PHQ-9 score (r = -0.72). The majority of activity was performed by the bedside (37%), and most physical (47%) and cognitive (54%) activities performed when alone. Patients undertook 5% (95% CI 2 to 9) less physical activity on the weekends compared with the weekdays. Conclusions: Levels of physical, cognitive and social activity of stroke patients were low and remained so even though level of independence and mood improved. These findings suggest the need to explore strategies to stimulate activity within rehabilitation environments. © The Author(s) 2013.

Background: Intracranial pressure elevation, peaking three to seven post-stroke is well recognized following large strokes. Data following small-moderate stroke are limited. Therapeutic hypothermia improves outcome after cardiac arrest, is strongly neuroprotective in experimental stroke, and is under clinical trial in stroke. Hypothermia lowers elevated intracranial pressure; however, rebound intracranial pressure elevation and neurological deterioration may occur during rewarming. Hypotheses: (1) Intracranial pressure increases 24h after moderate and small strokes. (2) Short-duration hypothermia-rewarming, instituted before intracranial pressure elevation, prevents this 24h intracranial pressure elevation. Methods: Long-Evans rats with two hour middle cerebral artery occlusion or outbred Wistar rats with three hour middle cerebral artery occlusion had intracranial pressure measured at baseline and 24h. Wistars were randomized to 2·5h hypothermia (32·5°C) or normothermia, commencing 1h after stroke. Results: In Long-Evans rats (n=5), intracranial pressure increased from 10·9±4·6mmHg at baseline to 32·4±11·4mmHg at 24h, infarct volume was 84·3±15·9mm3. In normothermic Wistars (n=10), intracranial pressure increased from 6·7±2·3mmHg to 31·6±9·3mmHg, infarct volume was 31·3±18·4mm3. In hypothermia-treated Wistars (n=10), 24h intracranial pressure did not increase (7·0±2·8mmHg, P<0·001 vs. normothermia), and infarct volume was smaller (15·4±11·8mm3, P<0·05). Conclusions: We saw major intracranial pressure elevation 24h after stroke in two rat strains, even after small strokes. Short-duration hypothermia prevented the intracranial pressure rise, an effect sustained for at least 18h after rewarming. The findings have potentially important implications for design of future clinical trials. © 2013 The Authors. International Journal of Stroke © 2013 World Stroke Organization.

In both the human and animal literature, it has largely been assumed that edema is the primary cause of intracranial pressure (ICP) elevation after stroke and that more edema equates to higher ICP. We recently demonstrated a dramatic ICP elevation 24 hours after small ischemic strokes in rats, with minimal edema. This ICP elevation was completely prevented by short-duration moderate hypothermia soon after stroke. Here, our aims were to determine the importance of edema in ICP elevation after stroke and whether mild hypothermia could prevent the ICP rise. Experimental stroke was performed in rats. ICP was monitored and short-duration mild (35¿°C) or moderate (32.5¿°C) hypothermia, or normothermia (37¿°C) was induced after stroke onset. Edema was measured in three studies, using wet¿dry weight calculations, T2-weighted magnetic resonance imaging, or histology. ICP increased 24 hours after stroke onset in all normothermic animals. Short-duration mild or moderate hypothermia prevented this rise. No correlation was seen between ¿ICP and edema or infarct volumes. Calculated rates of edema growth were orders of magnitude less than normal cerebrospinal fluid production rates. These data challenge current concepts and suggest that factors other than cerebral edema are the primary cause of the ICP elevation 24 hours after stroke onset.Journal of Cerebral Blood Flow & Metabolism advance online publication, 17 December 2014; doi:10.1038/jcbfm.2014.230.

Background: Many aspects of CSF dynamics are poorly understood due to the difficulties involved in quantification and visualization. In particular, there is debate surrounding the route of CSF drainage. Our aim was to quantify CSF flow, volume, and drainage route dynamics in vivo in young and aged spontaneously hypertensive rats (SHR) using a novel contrast-enhanced computed tomography (CT) method.Methods: ICP was recorded in young (2-5 months) and aged (16 months) SHR. Contrast was administered into the lateral ventricles bilaterally and sequential CT imaging was used to visualize the entire intracranial CSF system and CSF drainage routes. A customized contrast decay software module was used to quantify CSF flow at multiple locations.Results: ICP was significantly higher in aged rats than in young rats (11.52 ± 2.36 mmHg, versus 7.04 ± 2.89 mmHg, p = 0.03). Contrast was observed throughout the entire intracranial CSF system and was seen to enter the spinal canal and cross the cribriform plate into the olfactory mucosa within 9.1 ± 6.1 and 22.2 ± 7.1 minutes, respectively. No contrast was observed adjacent to the sagittal sinus. There were no significant differences between young and aged rats in either contrast distribution times or CSF flow rates. Mean flow rates (combined young and aged) were 3.0 ± 1.5 µL/min at the cerebral aqueduct; 3.5 ± 1.4 µL/min at the 3rd ventric= and 2.8 ± 0.9 µL/min at the 4th ventricle. Intracranial CSF volumes (and as percentage total brain volume) were 204 ± 97 µL (8.8 ± 4.3%) in the young and 275 ± 35 µL (10.8 ± 1.9%) in the aged animals (NS).Conclusions: We have demonstrated a contrast-enhanced CT technique for measuring and visualising CSF dynamics in vivo. These results indicate substantial drainage of CSF via spinal and olfactory routes, but there was little evidence of drainage via sagittal sinus arachnoid granulations in either young or aged animals. The data suggests that spinal and olfactory routes are the primary routes of CSF drainage and that sagittal sinus arachnoid granulations play a minor role, even in aged rats with higher ICP. © 2014 Murtha et al.; licensee BioMed Central Ltd.

Rationale: No evidence-based acute therapies exist for intracerebral hemorrhage. Intracerebral hemorrhage growth is an important determinant of patient outcome. Tranexamic acid is known to reduce hemorrhage in other conditions. Aim: The study aims to test the hypothesis that intracerebral hemorrhage patients selected with computed tomography angiography contrast extravasation 'spot sign' will have lower rates of hematoma growth when treated with intravenous tranexamic acid within 4·5-hours of stroke onset compared with placebo. Design: The Spot sign and Tranexamic acid On Preventing ICH growth - AUStralasia Trial is a multicenter, prospective, 1:1 randomized, double-blind, placebo-controlled, investigator-initiated, academic Phase II trial. Intracerebral hemorrhage patients fulfilling clinical criteria (e.g. Glasgow Coma Scale >7, intracerebral hemorrhage volume <70ml, no identified secondary cause of intracerebral hemorrhage, no thrombotic events within the previous 12 months, no planned surgery) and demonstrating contrast extravasation on computed tomography angiography will receive either intravenous tranexamic acid 1g 10-min bolus followed by 1g eight-hour infusion or placebo. A second computed tomography will be performed at 24 ± 3 hours to evaluate intracerebral hemorrhage growth and patients followed up for three-months. Study outcomes: The primary outcome measure is presence of intracerebral hemorrhage growth by 24 ± 3 hours, defined as either >33% or >6ml increase from baseline, and will be adjusted for baseline intracerebral hemorrhage volume. Secondary outcome measures include growth as a continuous measure, thromboembolic events, and the three-month modified Rankin Scale score. Discussion: This is the first trial to evaluate the efficacy of tranexamic acid in intracerebral hemorrhage patients selected based on an imaging biomarker of high likelihood of hematoma growth. The trial is registered as NCT01702636. © 2013 World Stroke Organization.

Background: Perfusion computed tomography is becoming more widely used as a clinical imaging tool to predict potentially salvageable tissue (ischemic penumbra) after ischemic stroke and guide reperfusion therapies. Aims: The study aims to determine whether there are important changes in perfusion computed tomography thresholds defining ischemic penumbra and infarct core over time following stroke. Methods: Permanent middle cerebral artery occlusion was performed in adult outbred Wistar rats (n=6) and serial perfusion computed tomography scans were taken every 30 mins for 2h. To define infarction thresholds at 1h and 2h post-stroke, separate groups of rats underwent 1h (n=6) and 2h (n=6) of middle cerebral artery occlusion followed by reperfusion. Infarct volumes were defined by histology at 24h. Co-registration with perfusion computed tomography maps (cerebral blood flow, cerebral blood volume, and mean transit time) permitted pixel-based analysis of thresholds defining infarction, using receiver operating characteristic curves. Results: Relative cerebral blood flow was the perfusion computed tomography parameter that most accurately predicted penumbra (area under the curve=0·698) and also infarct core (area under the curve=0·750). A relative cerebral blood flow threshold of <75% of mean contralateral cerebral blood flow most accurately predicted penumbral tissue at 0·5h (area under the curve=0·660), 1h (area under the curve=0·659), 1·5h (area under the curve=0·636), and 2h (area under the curve=0·664) after stroke onset. A relative cerebral blood flow threshold of <55% of mean contralateral most accurately predicted infarct core at 1h (area under the curve=0·765) and at 2h (area under the curve=0·689) after middle cerebral artery occlusion. Conclusions: The data provide perfusion computed tomography defined relative cerebral blood flow thresholds for infarct core and ischemic penumbra within the first two hours after experimental stroke in rats. These thresholds were shown to be stable to define the volume of infarct core and penumbra within this time window. © 2013 World Stroke Organization.

Background: Transient ischemic attacks and minor stroke entail considerable risk of completed stroke but this risk is reduced by prompt assessment and treatment. Risk can be stratified according to the ABCD2 prediction score. Current guidelines suggest specialist assessment and treatment within 24h for high-risk event (ABCD2 score 4-7) and seven-days for low-risk event (ABCD2 score =3). Aims: The study aims to establish paths to care and outcomes for patients referred by general practitioners and emergency departments to an Australian acute access transient ischemic attack service. Methods: This is a prospective audit. Primary outcomes were time from event to referral, from referral to clinic appointment, and from event to appointment. ABCD2 score was calculated for each event. Time from event was modeled using Cox proportional hazards regression. Results: There were 231 clinic attendees (general practitioner: 127; emergency department: 104). Mean time from event to referral was 9·2 days (SD 23·7, median 2), from referral to being seen in the clinic was 13·6 days (SD 19·0, median 7), and from event to being seen in the clinic was 17·2 days (SD 27·1, median 10). Of low-risk patients, 38·5% were seen within seven-days of event. Of high-risk patients, 36·7% were seen within one-day. ABCD2 score was not a significant predictor of any time interval from event to clinic attendance. There were no completed strokes prior to clinic attendance. Conclusions: Times from event to clinic assessment were in excess of current recommendations and risk stratification was suboptimal, though short-term outcomes were good. Improvements in referral mechanisms may enhance risk-stratification and triage. © 2013 World Stroke Organization.
