Very early poststroke aphasia therapy: A pilot randomized controlled efficacy trial

Background and purpose: Early stroke rehabilitation has shown benefits over spontaneous recovery. Insufficient evidence exists to determine the benefits of early aphasia intervention. We hypothesized that daily aphasia therapy would show better communication outcomes than usual care (UC) in early poststroke recovery. Method: This prospective, randomized, single-blinded, controlled trial was conducted in three acute-care hospitals in Perth, Australia, each with over 200 stroke admissions annually. Patients with acute stroke causing moderate to severe aphasia were recruited at a median of three-days (range: 0–10 days) to receive daily aphasia therapy or usual care therapy. Individually tailored, impairment-based intervention was provided for the acute hospital stay or intervention phase (median: 19 days; range: 5–76). Primary outcome measures were the aphasia quotient and functional communication profile at acute hospital discharge or four-weeks poststroke, whichever came first. A random-number generator and sealed envelopes were used to randomize participants. Assessments were completed by a blinded assessor. Results: Fifty-nine participants were recruited, with six withdrawals (10%) and seven deaths (12%) at six-months. Ninety percent had ischemic strokes, with 56·5% experiencing a total anterior circulation stroke. The group mean (±SD) age was 69·1 (±13·9) years. Six participants (18·75%) in the daily aphasia therapy group did not complete the minimum (150 min) therapy required for this study. The daily aphasia therapy intervention phase mean therapy session time was 45 min (range: 30–80) and the total mean amount of therapy for the daily aphasia therapy participants was 331 min (range: 30–1415). Four (15%) participants in the usual care group received therapy. The collective total therapy provided to these participants was 295 min over seven sessions. Usual care participants received an average of 10·5 min of therapy per week during the intervention phase. At the primary end point, a generalized estimating equations model demonstrated that after controlling for initial aphasia severity, participants receiving daily aphasia therapy scored 15·1 more points (P=0·010) on the aphasia quotient and 11·3 more points (P=0·004) on the functional communication profile than those receiving usual care therapy. Conclusions: Daily aphasia therapy in very early stroke recovery improved communication outcomes in people with moderate to severe aphasia

Improving access to evidence-based acute stroke services: development and evaluation of a health systems model to address equity of access issues

Level 1 evidence for management of patients with stroke in a dedicated Stroke Care Unit (SCU) demonstrates improved outcomes by about 20%. It has been estimated that 21% of Australian hospitals provide an SCU and that these SCUs are mainly located in either metropolitan sites and/or in hospitals with more than 300 beds. To address equity issues related to access to SCUs, the National Stroke Foundation and the Australian Government undertook the National Stroke Units Program. One program outcome was the development of a conceptual model of acute stroke service delivery. The development process and initial evaluation of the model are described. Use of the model to increase capacity within the health care system to treat stroke is discussed.<br /

Hospitals admitting at least 100 patients with stroke a year should have a stroke unit:a case study from Australia

BACKGROUND: Establishing a stroke unit (SU) in every hospital may be infeasible because of limited resources. In Australia, it is recommended that hospitals that admit ≥100 strokes per year should have a SU. We aimed to describe differences in processes of care and outcomes among hospitals with and without SUs admitting at least 100 patients/year. METHODS: National stroke audit data of 40 consecutive patients per hospital admitted between 1/7/2010-31/12/2010 and organizational survey for annual admissions were used. Descriptive analyses and multilevel regression were used to compare patient outcomes. Sensitivity analysis including only hospitals meeting all of the Australian SU criteria (e.g., co-location of beds; inter-professional team; weekly meetings; regular training) was performed. RESULTS: Two thousand eight hundred ninety-eight patients from 72/108 eligible hospitals completing the audit (SU = 60; patients: 2,481 [mean age 76 years; 55% male] and non-SU patients: 417 [mean age 77; 53% male]). Hospitals with SUs had greater adherence to recommended care processes than non-SU hospitals. Patients treated in a SU hospital had fewer new strokes while in hospital (OR: 0.20; 95% CI 0.06, 0.61) and there was a borderline reduction in the odds of dying in hospital compared to patients in non-SU hospitals (OR 0.57 95%CI 0.33, 1.00). Among SU hospitals meeting all SU criteria (n = 59; 91%) the adjusted odds of having a poor outcome was further reduced compared with patients attending non-SU hospitals. CONCLUSION: Hospitals annually admitting ≥100 patients with acute stroke should be prioritized for establishment of a SU that meet all recommended criteria to ensure better outcomes

Australian public's awareness of stroke warning signs improves after national multimedia campaigns

Background and Purpose: The aim of this study was to examine the reach and impact of the National Stroke Foundation (NSF) multimedia stroke warning sign campaigns across Australia. Methods: A total of 12 439 surveys were performed across 6 states during 6 years on random state–weighted samples of Australians ≥40 years old. Results: Awareness of stroke advertising increased 31% to 50% between 2004 and 2010 (P<0.001), as did the unprompted recall of ≥2 most common stroke warning signs 20% to 53% (P<0.001). Awareness of stroke advertising was independently associated with recalling ≥2 common signs (adjusted odds ratio=1.88, 95% confidence interval [1.74–2.04]; P<0.001). Awareness was not greater in respondents with previous stroke or risk factors, except atrial fibrillation. Conclusions: The Australian public’s awareness of stroke warning signs has improved since commencement of the NSF campaigns commensurate with greater awareness of stroke advertising. Public education efforts are worthwhile, and future efforts should focus on groups identified with low awareness or those at high risk of stroke

Thrombolysis implementation in stroke (TIPS): evaluating the effectiveness of a strategy to increase the adoption of best evidence practice - protocol for a cluster randomised controlled trial in acute stroke care

Background: Stroke is a leading cause of death and disability internationally. One of the three effective interventions in the acute phase of stroke care is thrombolytic therapy with tissue plasminogen activator (tPA), if given within 4.5 hours of onset to appropriate cases of ischaemic stroke. Objectives: To test the effectiveness of a multi-component multidisciplinary collaborative approach compared to usual care as a strategy for increasing thrombolysis rates for all stroke patients at intervention hospitals, while maintaining accepted benchmarks for low rates of intracranial haemorrhage and high rates of functional outcomes for both groups at three months. Methods and design: A cluster randomised controlled trial of 20 hospitals across 3 Australian states with 2 groups: multi- component multidisciplinary collaborative intervention as the experimental group and usual care as the control group. The intervention is based on behavioural theory and analysis of the steps, roles and barriers relating to rapid assessment for thrombolysis eligibility; it involves a comprehensive range of strategies addressing individual-level and system-level change at each site. The primary outcome is the difference in tPA rates between the two groups post-intervention. The secondary outcome is the proportion of tPA treated patients in both groups with good functional outcomes (modified Rankin Score (mRS <2) and the proportion with intracranial haemorrhage (mRS ≥2), compared to international benchmarks. Discussion: TIPS will trial a comprehensive, multi-component and multidisciplinary collaborative approach to improving thrombolysis rates at multiple sites. The trial has the potential to identify methods for optimal care which can be implemented for stroke patients during the acute phase. Study findings will include barriers and solutions to effective thrombolysis implementation and trial outcomes will be published whether significant or not.
