The role of stroke nurses in thrombolysis administration in Australia and the United Kingdom: A cross-sectional survey of current practice.

BACKGROUND: The role of stroke nurses in patient selection and administration of recombinant tissue plasminogen activator (rt-PA) for acute ischaemic stroke is evolving. OBJECTIVES: To compare differences in stroke nurses' practices related to rt-PA administration in Australia and the United Kingdom (UK) and to examine whether these differences influence rt-PA treatment rates. METHODS: A cross-sectional, self-administered questionnaire administered to a lead stroke clinician from hospitals known to provide rt-PA for acute ischaemic stroke. Chi-square tests were used to analyse between-country differences in ten pre-specified rt-PA practices. Non-parametric equality of medians test was used to assess within-country differences for likelihood of undertaking practices and association with rt-PA treatment rates. Reporting followed STROBE checklist. RESULTS: Response rate 68%; (Australia: 74% [n = 63/85]; UK: 65% [n = 93/144]). There were significant differences between countries for 7/10 practices. UK nurses were more likely to: request CT scan; screen patient for rt-PA suitability; gain informed consent; use telemedicine to assess, diagnose or treat; assist in the decision for rt-PA with Emergency Department physician or neurologist; and undergo training in rt-PA administration. Reported median hospital rt-PA treatment rates were 12% in the UK and 7.8% in Australia: (7.8%). In Australia, there was an association between higher treatment rates and nurses involvement in 5/10 practices; read and interpret CT scans; screen patient for rt-PA suitability; gain informed consent; assess suitability for rt-PA with neurologist/stroke physician; undergo training in rt-PA administration. There was no relationship between UK treatment rates and likelihood of a stroke nurse to undertake any of the ten rt-PA practices. CONCLUSION: Stroke nurses' active role in rt-PA administration can improve rt-PA treatment rates. Models of care that broaden stroke nurses' scope of practice to maximise rt-PA treatment rates for ischaemic stroke patients are needed. RELEVANCE TO CLINICAL PRACTICE: This study demonstrates that UK and Australian nurses play an important role in thrombolysis practices; however, they are underused. Formalising and extending the role of stroke nurses in rt-PA administration could potentially increase thrombolysis rates with clinical benefits for patients.

Non-pharmacological interventions for preventing delirium in hospitalised non-ICU patients.

BACKGROUND: Delirium is an acute neuropsychological disorder that is common in hospitalised patients. It can be distressing to patients and carers and it is associated with serious adverse outcomes. Treatment options for established delirium are limited and so prevention of delirium is desirable. Non-pharmacological interventions are thought to be important in delirium prevention.  OBJECTIVES: To assess the effectiveness of non-pharmacological interventions designed to prevent delirium in hospitalised patients outside intensive care units (ICU). SEARCH METHODS: We searched ALOIS, the specialised register of the Cochrane Dementia and Cognitive Improvement Group, with additional searches conducted in MEDLINE, Embase, PsycINFO, CINAHL, LILACS, Web of Science Core Collection, ClinicalTrials.gov and the World Health Organization Portal/ICTRP to 16 September 2020. There were no language or date restrictions applied to the electronic searches, and no methodological filters were used to restrict the search. SELECTION CRITERIA: We included randomised controlled trials (RCTs) of single and multicomponent non-pharmacological interventions for preventing delirium in hospitalised adults cared for outside intensive care or high dependency settings. We only included non-pharmacological interventions which were designed and implemented to prevent delirium.  DATA COLLECTION AND ANALYSIS: Two review authors independently examined titles and abstracts identified by the search for eligibility and extracted data from full-text articles. Any disagreements on eligibility and inclusion were resolved by consensus. We used standard Cochrane methodological procedures. The primary outcomes were: incidence of delirium; inpatient and later mortality; and new diagnosis of dementia. We included secondary and adverse outcomes as pre-specified in the review protocol. We used risk ratios (RRs) as measures of treatment effect for dichotomous outcomes and between-group mean differences for continuous outcomes. The certainty of the evidence was assessed using GRADE. A complementary exploratory analysis was undertaker using a Bayesian component network meta-analysis fixed-effect model to evaluate the comparative effectiveness of the individual components of multicomponent interventions and describe which components were most strongly associated with reducing the incidence of delirium. MAIN RESULTS: We included 22 RCTs that recruited a total of 5718 adult participants. Fourteen trials compared a multicomponent delirium prevention intervention with usual care. Two trials compared liberal and restrictive blood transfusion thresholds. The remaining six trials each investigated a different non-pharmacological intervention. Incidence of delirium was reported in all studies.  Using the Cochrane risk of bias tool, we identified risks of bias in all included trials. All were at high risk of performance bias as participants and personnel were not blinded to the interventions. Nine trials were at high risk of detection bias due to lack of blinding of outcome assessors and three more were at unclear risk in this domain.  Pooled data showed that multi-component non-pharmacological interventions probably reduce the incidence of delirium compared to usual care (10.5% incidence in the intervention group, compared to 18.4% in the control group, risk ratio (RR) 0.57, 95% confidence interval (CI) 0.46 to 0.71, I2 = 39%; 14 studies; 3693 participants; moderate-certainty evidence, downgraded due to risk of bias).  There may be little or no effect of multicomponent interventions on inpatient mortality compared to usual care (5.2% in the intervention group, compared to 4.5% in the control group, RR 1.17, 95% CI 0.79 to 1.74, I2 = 15%; 10 studies; 2640 participants; low-certainty evidence downgraded due to inconsistency and imprecision).  No studies of multicomponent interventions reported data on new diagnoses of dementia.  Multicomponent interventions may result in a small reduction of around a day in the duration of a delirium episode (mean difference (MD) -0.93, 95% CI -2.01 to 0.14 days, I2 = 65%; 351 participants; low-certainty evidence downgraded due to risk of bias and imprecision). The evidence is very uncertain about the effect of multicomponent interventions on delirium severity (standardised mean difference (SMD) -0.49, 95% CI -1.13 to 0.14, I2=64%; 147 participants; very low-certainty evidence downgraded due to risk of bias and serious imprecision). Multicomponent interventions may result in a reduction in hospital length of stay compared to usual care (MD -1.30 days, 95% CI -2.56 to -0.04 days, I2=91%; 3351 participants; low-certainty evidence downgraded due to risk of bias and inconsistency), but little to no difference in new care home admission at the time of hospital discharge (RR 0.77, 95% CI 0.55 to 1.07; 536 participants; low-certainty evidence downgraded due to risk of bias and imprecision). Reporting of other adverse outcomes was limited.  Our exploratory component network meta-analysis found that re-orientation (including use of familiar objects), cognitive stimulation and sleep hygiene were associated with reduced risk of incident delirium. Attention to nutrition and hydration, oxygenation, medication review, assessment of mood and bowel and bladder care were probably associated with a reduction in incident delirium but estimates included the possibility of no benefit or harm.  Reducing sensory deprivation, identification of infection, mobilisation and pain control all had summary estimates that suggested potential increases in delirium incidence, but the uncertainty in the estimates was substantial.  Evidence from two trials suggests that use of a liberal transfusion threshold over a restrictive transfusion threshold probably results in little to no difference in incident delirium (RR 0.92, 95% CI 0.62 to 1.36; I2 = 9%; 294 participants; moderate-certainty evidence downgraded due to risk of bias).  Six other interventions were examined, but evidence for each was limited to single studies and we identified no evidence of delirium prevention.  AUTHORS' CONCLUSIONS: There is moderate-certainty evidence regarding the benefit of multicomponent non-pharmacological interventions for the prevention of delirium in hospitalised adults, estimated to reduce incidence by 43% compared to usual care. We found no evidence of an effect on mortality. There is emerging evidence that these interventions may reduce hospital length of stay, with a trend towards reduced delirium duration, although the effect on delirium severity remains uncertain. Further research should focus on implementation and detailed analysis of the components of the interventions to support more effective, tailored practice recommendations.

Testing a systematic approach to identify and prioritise barriers to successful implementation of a complex healthcare intervention.

BACKGROUND: Multiple barriers may inhibit the adoption of clinical interventions and impede successful implementation. Use of standardised methods to prioritise barriers to target when selecting implementation interventions is an understudied area of implementation research. The aim of this study was to describe a method to identify and prioritise barriers to the implementation of clinical practice elements which were used to inform the development of the T3 trial implementation intervention (Triage, Treatment [thrombolysis administration; monitoring and management of temperature, blood glucose levels, and swallowing difficulties] and Transfer of stroke patients from Emergency Departments [ED]). METHODS: A survey was developed based on a literature review and data from a complementary trial to identify the commonly reported barriers for the nine T3 clinical care elements. This was administered via a web-based questionnaire to a purposive sample of Australian multidisciplinary clinicians and managers in acute stroke care. The questionnaire addressed barriers to each of the nine T3 trial clinical care elements. Participants produced two ranked lists: on their perception of: firstly, how influential each barrier was in preventing clinicians from performing the clinical care element (influence attribute); and secondly how difficult the barrier was to overcome (difficulty attribute). The rankings for both influence and difficulty were combined to classify the barriers according to three categories ('least desirable', desirable' or 'most desirable' to target) to assist interpretation. RESULTS: All invited participants completed the survey; (n = 17; 35% medical, 35% nursing, 18% speech pathology, 12% bed managers). The barriers classified as most desirable to target and overcome were a 'lack of protocols for the management of fever' and 'not enough blood glucose monitoring machines'. CONCLUSIONS: A structured decision-support procedure has been illustrated and successfully applied to identify and prioritise barriers to target within an implementation intervention. This approach may prove to be a useful in other studies and as an adjunct to undertaking barrier assessments within individual sites when planning implementation interventions.

Implementing a complex rehabilitation intervention in a stroke trial: a qualitative process evaluation of AVERT.

BACKGROUND: The implementation of multidisciplinary stroke rehabilitation interventions is challenging, even when the intervention is evidence-based. Very little is known about the implementation of complex interventions in rehabilitation clinical trials. The aim of study was to better understand how the implementation of a rehabilitation intervention in a clinical trial within acute stroke units is experienced by the staff involved. This qualitative process evaluation was part of a large Phase III stroke rehabilitation trial (AVERT). METHODS: A descriptive qualitative approach was used. We purposively sampled 53 allied health and nursing staff from 19 acute stroke units in Australia, New Zealand and Scotland. Semi-structured interviews were conducted by phone, voice-internet, or face to face. Digitally recorded interviews were transcribed and analysed by two researchers using rigorous thematic analysis. RESULTS: Our analysis uncovered ten important themes that provide insight into the challenges of implementing complex new rehabilitation practices within complex care settings, plus factors and strategies that assisted implementation. Themes were grouped into three main categories: staff experience of implementing the trial intervention, barriers to implementation, and overcoming the barriers. Participation in the trial was challenging but had personal rewards and improved teamwork at some sites. Over the years that the trial ran some staff perceived a change in usual care. Barriers to trial implementation at some sites included poor teamwork, inadequate staffing, various organisational barriers, staff attitudes and beliefs, and patient-related barriers. Participants described successful implementation strategies that were built on interdisciplinary teamwork, education and strong leadership to 'get staff on board', and developing different ways of working. CONCLUSIONS: The AVERT stroke rehabilitation trial required commitment to deliver an intervention that needed strong collaboration between nurses and physiotherapists and was different to current care models. This qualitative process evaluation contributes unique insights into factors that may be critical to successful trials teams, and as AVERT was a pragmatic trial, success factors to delivering complex intervention in clinical practice. TRIAL REGISTRATION: AVERT registered with Australian New Zealand Clinical Trials Registry ACTRN12606000185561 .

Early mobilization after stroke: an example of an individual patient data meta-analysis of a complex intervention.

BACKGROUND AND PURPOSE: Very early mobilization (VEM) is a distinctive characteristic of care in some stroke units; however, evidence of the effectiveness of this approach is limited. To date, only 2 phase II trials have compared VEM with standard care: A Very Early Rehabilitation Trial (AVERT) in Australia and the recently completed Very Early Rehabilitation or Intensive Telemetry after Stroke trial in the United Kingdom. The Very Early Rehabilitation or Intensive Telemetry after Stroke protocol was designed to complement that of AVERT in a number of key areas. The aim of this analysis was to investigate the impact of VEM on independence by pooling data from these 2 comparable trials. METHODS: Individual data from the 2 trials were pooled. Overall, patients were between 27 and 97 years old, had first or recurring stroke, and were treated within 36 hours after stroke onset. The primary outcome was independence, defined as modified Rankin scale score of 0 to 2 at 3 months. The secondary outcomes included complications of immobility and activities of daily living. Logistic regression was used to assess the effect of VEM on outcome, adjusting for known confounders including age, baseline stroke severity, and premorbid modified Rankin scale score. Findings-All patients in AVERT and Very Early Rehabilitation or Intensive Telemetry after Stroke were included, resulting in 54 patients in the VEM group and 49 patients in the standard care group. The baseline characteristics of VEM patients were largely comparable with standard care patients. Time to first mobilization from symptom onset was significantly shorter among VEM patients (median, 21 hours; interquartile range, 15.8-27.8 hours) compared with standard care patients (median, 31 hours; interquartile range, 23.0-41.2 hours). VEM patients had significantly greater odds of independence compared with standard care patients (adjusted odds ratio, 3.11; 95% confidence interval, 1.03-9.33). CONCLUSIONS: Planned collaborations between stroke researchers to conduct trials with common protocols and outcome measures can help advance rehabilitation science. VEM was associated with improved independence at 3 months compared with standard care. However, both trials are limited by small sample sizes. Larger trials (such as AVERT phase III) are still needed in this field.

Does the Addition of Non-Approved Inclusion and Exclusion Criteria for rtPA Impact Treatment Rates? Findings in Australia, the UK, and the USA.

BACKGROUND: Strict criteria for recombinant tissue plasminogen activator (rtPA) eligibility are stipulated on licences for use in ischaemic stroke; however, practitioners may also add non-standard rtPA criteria. We examined eligibility criteria variation in 3 English-speaking countries including use of non-standard criteria, in relation to rtPA treatment rates. METHODS: Surveys were mailed to 566 eligible hospitals in Australia (AUS), the UK, and the USA. Criteria were pre-classified as standard (approved indication and contraindications) or non-standard (approved warning or researcher "decoy"). Percentage for criterion selection was calculated/compared; linear regression was used to assess the association between use of non-standard criteria and rtPA treatment rates, and to identify factors associated with addition of non-standard criteria. RESULTS: Response rates were 74% AUS, 65% UK, and 68% USA; mean rtPA treatment rates were 8.7% AUS, 12.7% UK, and 8.7% USA. Median percentage of non-standard inclusions was 33% (all 3 countries) and included National Institutes of Health Stroke Scale (NIHSS) scores > 4, computed tomography (CT) angiography documented occlusion, and favourable CT perfusion. Median percentage of non-standard exclusions was 25% AUS, 28% UK, and 60% USA, and included depressed consciousness, NIHSS > 25, and use of antihypertensive infusions. No AUS or UK sites selected 100% of standard exclusions. CONCLUSIONS: Non-standard criteria for rtPA eligibility were evident in all three countries and could, in part, explain comparably low use of rtPA. Differences in the use of standard criteria may signify practitioner intolerance for those derived from original efficacy studies that are no longer relevant.

Inclusion of a care bundle for fever, hyperglycaemia and swallow management in a National Audit for acute stroke: evidence of upscale and spread.

BACKGROUND: In the Quality in Acute Stroke Care (QASC) trial undertaken in stroke units (SUs) located in New South Wales (NSW), Australia (2005-2010), facilitated implementation of a nurse-led care bundle to manage fever, hyperglycaemia and swallowing (FeSS protocols) reduced death and disability for patients with stroke. We aimed to determine subsequent adherence to the bundled FeSS processes (reflective of the protocols) between 2013 and 2017 in Australian hospitals, and examine whether changes in adherence to these processes varied based on previous participation in the QASC trial or subsequent statewide scale-up (QASCIP-Quality in Acute Stroke Care Implementation Project) and presence of an SU. METHODS: Cross-sectional, observational study using self-reported organisational survey and retrospective clinical audit data from the National Acute Services Stroke Audit (2013, 2015, 2017). Mixed-effects logistic regression was performed with dependent variables: (1) composite outcome measure reflecting compliance with the FeSS protocols and (2) individual FeSS processes, including the year of audit as an independent variable, adjusted for correlation of outcomes within hospital. Separate models including interaction terms between the year of audit and previous participation in QASC/QASCIP and year of audit and SU were also generated. RESULTS: Hospital participation included the following: 2013-124 hospitals, 3741 cases; 2015-112 hospitals, 4087 cases; and 2017-117 hospitals, 4192 cases. An 80% increase in the odds of receiving the composite outcome in 2017 compared to 2013 was found (2013, 30%; 2017, 41%; OR 1.8; 95% CI 1.6, 2.0; p < 0.001). The odds of FeSS adherence from 2013 to 2017 was greater for hospitals that had participated in QASC/QASCIP relative to those that had not (participated OR 2.1; 95% CI 1.7, 2.7; not participated OR 1.6; 95% CI 1.4, 1.8; p = 0.03). Similar uptake in adherence was evident in hospitals with and without an SU between 2013 and 2017. CONCLUSION: The use of the FeSS protocols within Australia increased from 2013 to 2017 with the inclusion of these care processes in the National Audit. Greater uptake in hospitals previously involved in QASC/QASCIP was evident. Our implementation methods may be useful for other national initiatives for improving access to evidence-based practice.

The interaction between policy and education using stroke as an example.

This paper discusses the interaction between healthcare policy at the European, UK and Scottish levels and the funding of education that underpins specific health policy priorities. Stroke is used throughout to illustrate the relationship between a designated European and UK health priority and the translation of that priority into clinical delivery. The necessity to build a responsive and sustainable culture to address the healthcare education that underpins changing healthcare policies is emphasized.

The evidence-base for stroke education in care homes.

RESEARCH QUESTIONS: 1. What are registered care home nurses' educational priorities regarding stroke care? 2. What are senior care home assistants' educational priorities regarding stroke care? 3. How do care home nurses conceive stroke care will be delivered in 2010? STUDY DESIGN: This was a 2-year study using focus groups, stroke guidelines, professional recommendations and stroke literature for the development of a questionnaire survey for data collection. Workshops provided study feedback to participants. Data were collected in 2005-2006. STUDY SITE: Greater Glasgow NHS Health Board. POPULATION AND SAMPLE: A stratified random selection of 16 private, 3 voluntary and 6 NHS continuing care homes from which a sample of 115 trained nurses and 19 senior care assistants was drawn. RESULTS: The overall response rate for care home nurses was 64.3% and for senior care assistants, 73.6%. Both care home nurses and senior care assistants preferred accredited stroke education. Care home nurses wanted more training in stroke assessment, rehabilitation and acute interventions whereas senior care assistants wanted more in managing depression, general stroke information and communicating with dysphasic residents. Senior care assistants needed more information on multidisciplinary team working while care home nurses were more concerned with ethical decision-making, accountability and goal setting. CONCLUSIONS: Care home staff need and want more stroke training. They are clear that stroke education should be to the benefit of their resident population. Guidelines on stroke care should be developed for care homes and these should incorporate support for continuing professional learning in relation to the resident who has had a stroke.

Stroke education for healthcare professionals: making it fit for purpose.

TITLE: Stroke education for healthcare professionals: Making it fit for purpose. RESEARCH QUESTIONS: 1. What are healthcare professionals' (HCPs) educational priorities regarding stroke care? 2. Do stroke care priorities vary across the primary and secondary sectors? 3. How do HCPs conceive stroke care will be delivered in 2010? STUDY DESIGN: This was a two-year study using focus groups and interviews for instrument development, questionnaires for data collection and workshops to provide study feedback. Data were collected in 2005-06. STUDY SITE: One Scottish health board. INCLUSION CRITERIA: All National Health Service healthcare professionals working wherever stroke care occurred. POPULATION AND SAMPLE: Participants were drawn from 4 university teaching hospitals, 2 community hospitals, 1 geriatric medicine day hospital, 48 general practices (GPs), 12 care homes and 15 community teams. The sample comprised 155 doctors, 313 nurses, 133 therapists (physiotherapists, occupational therapists, speech and language therapists), and 29 'other HCPs' (14 dieticians, 7 pharmacists, 2 podiatrists and 6 psychologists). RESULTS: HCPs prefer face-to-face, accredited education but blended approaches are required that accommodate uni- and multidisciplinary demands. Doctors and nurses are more inclined towards discipline-specific training compared to therapists and other healthcare professionals (HCPs). HCPs in primary care and stroke units want more information on the social impact of stroke while those working in stroke units in particular are concerned with leadership in the multidisciplinary team. Nurses are the most interested in teaching patients and carers. CONCLUSIONS: Stroke requires more specialist stroke staff, the upskilling of current staff and a national education pathway given that stroke care is most effectively managed by specialists with specific clinical skills. The current government push towards a flexible workforce is welcome but should be educationally-sound and recognise the career aspirations of healthcare professionals.

Development of a theory-informed implementation intervention to improve the triage, treatment and transfer of stroke patients in emergency departments using the Theoretical Domains Framework (TDF): the T3 Trial.

BACKGROUND: Theoretical frameworks and models based on behaviour change theories are increasingly used in the development of implementation interventions. Development of an implementation intervention is often based on the available evidence base and practical issues, i.e. feasibility and acceptability. The aim of this study was to describe the development of an implementation intervention for the T3 Trial (Triage, Treatment and Transfer of patients with stroke in emergency departments (EDs)) using theory to recommend behaviour change techniques (BCTs) and drawing on the research evidence base and practical issues of feasibility and acceptability. METHODS: A stepped method for developing complex interventions based on theory, evidence and practical issues was adapted using the following steps: (1) Who needs to do what, differently? (2) Using a theoretical framework, which barriers and enablers need to be addressed? (3) Which intervention components (behaviour change techniques and mode(s) of delivery) could overcome the modifiable barriers and enhance the enablers? A researcher panel was convened to review the list of BCTs recommended for use and to identify the most feasible and acceptable techniques to adopt. RESULTS: Seventy-six barriers were reported by hospital staff who attended the workshops (step 1: thirteen TDF domains likely to influence the implementation of the T3 Trial clinical intervention were identified by the researchers; step 2: the researcher panellists then selected one third of the BCTs recommended for use as appropriate for the clinical context of the ED and, using the enabler workshop data, devised enabling strategies for each of the selected BCTs; and step 3: the final implementation intervention consisted of 27 BCTs). CONCLUSIONS: The TDF was successfully applied in all steps of developing an implementation intervention for the T3 Trial clinical intervention. The use of researcher panel opinion was an essential part of the BCT selection process to incorporate both research evidence and expert judgment. It is recommended that this stepped approach (theory, evidence and practical issues of feasibility and acceptability) is used to develop highly reportable implementation interventions. The classifying of BCTs using recognised implementation intervention components will facilitate generalisability and sharing across different conditions and clinical settings.

Identifying the barriers and enablers for a triage, treatment, and transfer clinical intervention to manage acute stroke patients in the emergency department: a systematic review using the theoretical domains framework (TDF).

BACKGROUND: Clinical guidelines recommend that assessment and management of patients with stroke commences early including in emergency departments (ED). To inform the development of an implementation intervention targeted in ED, we conducted a systematic review of qualitative and quantitative studies to identify relevant barriers and enablers to six key clinical behaviours in acute stroke care: appropriate triage, thrombolysis administration, monitoring and management of temperature, blood glucose levels, and of swallowing difficulties and transfer of stroke patients in ED. METHODS: Studies of any design, conducted in ED, where barriers or enablers based on primary data were identified for one or more of these six clinical behaviours. Major biomedical databases (CINAHL, OVID SP EMBASE, OVID SP MEDLINE) were searched using comprehensive search strategies. The barriers and enablers were categorised using the theoretical domains framework (TDF). The behaviour change technique (BCT) that best aligned to the strategy each enabler represented was selected for each of the reported enablers using a standard taxonomy. RESULTS: Five qualitative studies and four surveys out of the 44 studies identified met the selection criteria. The majority of barriers reported corresponded with the TDF domains of "environmental, context and resources" (such as stressful working conditions or lack of resources) and "knowledge" (such as lack of guideline awareness or familiarity). The majority of enablers corresponded with the domains of "knowledge" (such as education for physicians on the calculated risk of haemorrhage following intravenous thrombolysis [tPA]) and "skills" (such as providing opportunity to treat stroke cases of varying complexity). The total number of BCTs assigned was 18. The BCTs most frequently assigned to the reported enablers were "focus on past success" and "information about health consequences." CONCLUSIONS: Barriers and enablers for the delivery of key evidence-based protocols in an emergency setting have been identified and interpreted within a relevant theoretical framework. This new knowledge has since been used to select specific BCTs to implement evidence-based care in an ED setting. It is recommended that findings from similar future reviews adopt a similar theoretical approach. In particular, the use of existing matrices to assist the selection of relevant BCTs.

Approaches to economic evaluations of stroke rehabilitation.

Many stroke rehabilitation services and interventions are complex in that they involve a number of components, interactions, and outcomes. Much of the onus of stroke care lies with rehabilitation services and because stroke rehabilitation is highly resource intensive, it is important for policy makers to consider the potential trade-offs between all relevant costs and benefits. The primary aim of this systematic review was to assess the methods used to conduct economic evaluations of stroke rehabilitation. Studies that compared two or more alternative stroke rehabilitation interventions or services with the costs and outcomes being examined for each alternative were included. EMBASE, MEDLINE In-Process, and National Health Service's Economic Evaluation Database were searched using search strategies. The methodological quality of the included studies was appraised using a checklist for the conduct and reporting of economic evaluations. Twenty-one studies met the selection criteria. The economic evaluations in the majority of these studies were inadequate based on their ability to identify, measure, and value all resources and benefits pertinent to the complexity of stroke rehabilitation. This study highlights that complex interventions such as stroke rehabilitation have widespread effects, which may not be represented by the changes on a single outcome. This study recommends the adoption of a wider cost and benefit perspective in the economic evaluations of complex interventions. It supports a move away from conventional economic evaluation and decision making, based purely on cost-effectiveness, toward multicriteria decision analysis frameworks for complex interventions, where a broader range of criteria may be assessed by policy makers.

Predictors of poststroke mobility: systematic review.

Regaining poststroke mobility is considered a primary goal of the stroke patient in early rehabilitation. Predictive recovery of poststroke mobility is clinically important, and provides important information to healthcare professionals, patients and their families. We conducted a systematic review aimed at identifying the predictive or associated baseline factors, assessed within one-week of stroke onset, and the recovery of poststroke mobility within 30 days. A comprehensive search strategy was applied to all major electronic databases to identify potentially relevant studies. Included in the review are two studies that evaluate the predictive value of baseline factors by developing a prognostic model, and three studies that assess the baseline factors that were associated with the outcome by univariate analysis. Walking is the most commonly assessed mobility outcome; age, the severity of paresis, reduced leg power, presence of hemianopia, size of brain lesion and type of stroke were shown to be predictive or associated with walking within 30 days poststroke. This review has identified the potential predictors of the recovery of mobility poststroke. There is a need to explore and validate these predictors in other patient cohorts, and consider additional factors believed to be associated with mobility. The recovery of mobility other than walking also needs investigation. In order to move prognostic research in stroke forward, a collaborative approach to sharing and collecting data is recommended.
