Addressing the Evidence Gap in Stroke Rehabilitation for Complex Patients: A Preliminary Research Agenda.

Evidence suggests that a stroke occurs in isolation (no comorbid conditions) in less than 6% of patients. Multimorbidity, compounded by psychosocial issues, makes treatment and recovery for stroke increasingly complex. Recent research and health policy documents called for a better understanding of the needs of this patient population, and for the development and testing of models of care that meet their needs. A research agenda specific to complexity is required. The primary objective of the think tank was to identify and prioritize research questions that meet the information needs of stakeholders, and to develop a research agenda specific to stroke rehabilitation and patient complexity. A modified Delphi and World Café approach underpinned the think tank meeting, approaches well recognized to foster interaction, dialogue, and collaboration between stakeholders. Forty-three researchers, clinicians, and policymakers attended a 2-day meeting. Initial question-generating activities resulted in 120 potential research questions. Sixteen high-priority research questions were identified, focusing on predetermined complexity characteristics-multimorbidity, social determinants, patient characteristics, social supports, and system factors. The final questions are presented as a prioritized research framework. An emergent result of this activity is the development of a complexity and stroke rehabilitation research network. The research agenda reflects topics of importance to stakeholders working with stroke patients with increasingly complex care needs. This robust process resulted in a preliminary research agenda that could provide policymakers with the evidence needed to make improvements toward better-organized services, better coordination between settings, improved patient outcomes, and lower system costs.

Supporting the implementation of stroke quality-based procedures (QBPs): a mixed methods evaluation to identify knowledge translation activities, knowledge translation interventions, and determinants of implementation across Ontario.

BACKGROUND: In 2013, Health Quality Ontario introduced stroke quality-based procedures (QBPs) to promote use of evidence-based practices for patients with stroke in Ontario hospitals. The study purpose was to: (a) describe the knowledge translation (KT) interventions used to support stroke QBP implementation, (b) assess differences in the planned and reported KT interventions by region, and (c) explore determinants perceived to have affected outcomes. METHODS: A mixed methods approach was used to evaluate: activities, KT interventions, and determinants of stroke QBP implementation. In Phase 1, a document review of regional stroke network work plans was conducted to capture the types of KT activities planned at a regional level; these were mapped to the knowledge to action framework. In Phase 2, we surveyed Ontario hospital staff to identify the KT interventions used to support QBP implementation at an organizational level. Phase 3 involved qualitative interviews with staff to elucidate deeper understanding of survey findings. RESULTS: Of the 446 activities identified in the document review, the most common were 'dissemination' (24.2%; n = 108), 'implementation' (22.6%; n = 101), 'implementation planning' (15.0%; n = 67), and 'knowledge tools' (10.5%; n = 47). Based on survey data (n = 489), commonly reported KT interventions included: staff educational meetings (43.1%; n = 154), champions (41.5%; n = 148), and staff educational materials (40.6%; n = 145). Survey participants perceived stroke QBP implementation to be successful (median = 5/7; interquartile range = 4-6; range = 1-7; n = 335). Forty-four people (e.g., managers, senior leaders, regional stroke network representatives, and frontline staff) participated in interviews/focus groups. Perceived facilitators to QBP implementation included networks and collaborations with external organizations, leadership engagement, and hospital prioritization of stroke QBP. Perceived barriers included lack of funding, size of the hospital (i.e., too small), lack of resources (i.e., staff and time), and simultaneous implementation of other QBPs. CONCLUSIONS: Information on the types of activities and KT interventions used to support stroke QBP implementation and the key determinants influencing uptake of stroke QBPs can be used to inform future activities including the development and evaluation of interventions to address barriers and leverage facilitators.

The characteristics of stroke units in Ontario: a pan-provincial survey.

BACKGROUND: Previous studies have demonstrated that organized, multidisciplinary care is the cornerstone of current strategies to reduce the death and disability caused by stroke. Identification of stroke units and an understanding of their composition and operation would provide insight for the further actions required to improve stroke care. The objective of this study was to identify and survey stroke units in Canada's largest province, Ontario (population of 13 million) in order to describe availability, structure, staffing, processes of care, and type of population stroke units serve. METHODS: The Ontario Stroke Network (2011) list of stroke units and snowball sampling was used to identify all stroke units. During 2013 - 2014 an interviewer conducted telephone surveys with the stroke unit managers using closed and semi-open ended questions. Descriptive statistics were used to summarize survey responses. RESULTS: The survey identified 32 stroke units, and a respondent from every stroke unit (100% response rate) was interviewed. Twenty one were acute stroke units, 10 were integrated stroke units and one was classified as a rehabilitation stroke unit. Stroke units were available in all 14 Local Health Integration Networks except Central West. The estimated average number of stroke patients served per stroke unit was 604 with six-fold variation (242 to 1480) across the province. The typical population served in stroke units were patients with either ischemic or hemorrhagic stroke. Data consistently reported on the processes of stroke care, including the availability of multidisciplinary staff, specific diagnostic imaging, use of validated assessment tools, and the delivery of patient education. Details about the core components of stoke care were provided by 16 stroke units (50%). CONCLUSIONS: This study demonstrates the heterogeneous structure of stroke units in Ontario and signaled potential disparity in access to stroke units. Many core components are in place, but half of the stroke units in Ontario do not meet all criteria. Areas for potential improvement include stroke care training for the multidisciplinary team, provision of individualized rehabilitation plans, and early discharge assessment.

Mechanical Thrombectomy in Acute Ischemic Stroke: A Systematic Review.

Although intravenous thrombolysis increases the probability of a good functional outcome in carefully selected patients with acute ischemic stroke, a substantial proportion of patients who receive thrombolysis do not have a good outcome. Several recent trials of mechanical thrombectomy appear to indicate that this treatment may be superior to thrombolysis. We therefore conducted a systematic review and meta-analysis to evaluate the clinical effectiveness and safety of new-generation mechanical thrombectomy devices with intravenous thrombolysis (if eligible) compared with intravenous thrombolysis (if eligible) in patients with acute ischemic stroke caused by a proximal intracranial occlusion. We systematically searched seven databases for randomized controlled trials published between January 2005 and March 2015 comparing stent retrievers or thromboaspiration devices with best medical therapy (with or without intravenous thrombolysis) in adults with acute ischemic stroke. We assessed risk of bias and overall quality of the included trials. We combined the data using a fixed or random effects meta-analysis, where appropriate. We identified 1579 studies; of these, we evaluated 122 full-text papers and included five randomized control trials (n=1287). Compared with patients treated medically, patients who received mechanical thrombectomy were more likely to be functionally independent as measured by a modified Rankin score of 0-2 (odds ratio, 2.39; 95% confidence interval, 1.88-3.04; I2=0%). This finding was robust to subgroup analysis. Mortality and symptomatic intracerebral hemorrhage were not significantly different between the two groups. Mechanical thrombectomy significantly improves functional independence in appropriately selected patients with acute ischemic stroke.

Stroke education for nurses through a technology-enabled program.

Today's nurse faces many challenges in the workplace. Required to keep up in a constantly changing knowledge-based environment, he or she must balance complex professional responsibilities, staffing shortages, and increased acuity among the patient population. Continuing education must, therefore, be highly flexible and responsive to the personal and professional needs of the nurse learner. Technology-supported continuing education is suggested to be an appropriate way of meeting the learning needs of busy working nurses. The Stroke Best Practices for Nursing project used three complementary and integrated educational technologies-a-Web-based learning site, Web casting (live and archived), and two-way interactive videoconferencing--to deliver a minicourse focused on best practice stroke care to nurses working in northeastern and northwestern Ontario, a geographical area of approximately 600 km. In total, 96 nurses participated in the educational part of the program; 46 of the 96 (47%) took part in the assessment of the program. On the basis of this assessment strategy and the nurses' requests for other programs that do not use traditional face-to-face classrooms and lecture, the value of using educational technologies in health-based continuing education was strongly identified. This article describes key components of the project and celebrates the partnership among the organizing stakeholders: faculty in the school of nursing at the Laurentian University, the West Greater Toronto Area Stroke Network, and the Ontario Telemedicine Network. The article further describes findings related to the program's impact on participants' perceptions of competence as caregivers for stroke patients, participants' confidence using technology for educational purposes, and participants' satisfaction with the overall program.

Timely access to inpatient rehabilitation after stroke: a qualitative study of perceived barriers and potential solutions in Ontario, Canada.

PURPOSE: Stroke units have been established as best practice care, in part because they offer timely initiation of rehabilitation. Experts in Ontario, Canada recommend that eligible patients be transferred to inpatient rehabilitation (on average) by day 5 after ischemic stroke and day 7 after a hemorrhagic stroke. This study explores perceived barriers to implementation of these recommendations and potential solutions. METHOD: Exploratory focus groups were held with stakeholders from five geographically diverse regions across Ontario between September 2011 and January 2012. Participants were asked to consider the recommendations, list perceived barriers and to collectively discuss potential solutions. Data analysis included coding of transcribed data, sorting material to identify themes and confronting themes with a formalized body of knowledge. RESULTS: Barriers identified by participants fell into three categories: patient-centered, clinician-focused and resource or system based, within these, specific challenges included managing patients' medical and emotional readiness for rehabilitation, timely completion of medical tests, staff comfort in discharging patients, dedicated transportation and funding-related concerns. CONCLUSIONS: The structure of Ontario's health care system presents challenges to early transfer of stroke patients to inpatient rehabilitation, yet the stakeholders consulted in this study felt that these could be addressed with proper planning, improved coordination and targeted investment. Implications for rehabilitation Stroke units are a well-established best practice in stroke care and timely access to rehabilitation is a key component of their effectiveness. Stroke experts in Ontario, Canada recommend transfer of suitable patients to inpatient rehabilitation on day 5 and day 7, on average, after ischemic and hemorrhagic stroke, respectively. Stakeholders report that meeting these targets may require some adjustments to local processes of care, many of which can be achieved with little to no financial investment.

Stroke rehabilitation evidence and comorbidity: a systematic scoping review of randomized controlled trials.

BACKGROUND: Most strokes occur in the context of other medical diagnoses. Currently, stroke rehabilitation evidence reviews have not synthesized or presented evidence with a focus on comorbidities and correspondingly may not align with current patient population. The purpose of this review was to determine the extent and nature of randomized controlled trial stroke rehabilitation evidence that included patients with multimorbidity. METHODS: A systematic scoping review was conducted. Electronic databases were searched using a combination of terms related to "stroke" and "rehabilitation." Selection criteria captured inpatient rehabilitation studies. Methods were modified to account for the amount of literature, classified by study design, and randomized controlled trials (RCTs) were abstracted. RESULTS: The database search yielded 10771 unique articles. Screening resulted in 428 included RCTs. Three studies explicitly included patients with a comorbid condition. Fifteen percent of articles did not specify additional conditions that were excluded. Impaired cognition was the most commonly excluded condition. Approximately 37% of articles excluded patients who had experienced a previous stroke. Twenty-four percent excluded patients one or more Charlson Index condition, and 83% excluded patients with at least one other medical condition. CONCLUSIONS: This review represents a first attempt to map literature on stroke rehabilitation related to co/multimorbidity and identify gaps in existing research. Existing evidence on stroke rehabilitation often excluded individuals with comorbidities. This is problematic as the evidence that is used to generate clinical guidelines may not match the patient typically seen in practice. The use of alternate research methods are therefore needed for studying the care of individuals with stroke and multimorbidity.

Mechanical thrombectomy in patients with acute ischemic stroke: a cost-utility analysis.

BACKGROUND: The beneficial effects of endovascular treatment with new-generation mechanical thrombectomy devices compared with intravenous thrombolysis alone to treat acute large-artery ischemic stroke have been shown in randomized controlled trials (RCTs). This study aimed to estimate the cost utility of mechanical thrombectomy compared with the established standard of care. METHODS: We developed a Markov decision process analytic model to assess the cost-effectiveness of treatment with mechanical thrombectomy plus intravenous thrombolysis versus treatment with intravenous thrombolysis alone from the public payer perspective in Canada. We conducted comprehensive literature searches to populate model inputs. We estimated the efficacy of mechanical thrombectomy plus intravenous thrombolysis from a meta-analysis of 5 RCTs, and we used data from the Oxford Vascular Study to model long-term clinical outcomes. We calculated incremental cost-effectiveness ratios (ICER) using a 5-year time horizon. RESULTS: The base case analysis showed the cost and effectiveness of treatment with mechanical thrombectomy plus intravenous thrombolysis to be $126 939 and 1.484 quality-adjusted life-years (QALYs), respectively, and the cost and effectiveness of treatment with intravenous thrombolysis alone to be $124 419 and 1.273 QALYs, respectively. The mechanical thrombectomy plus intravenous thrombolysis strategy was associated with an ICER of $11 990 per QALY gained. Probabilistic sensitivity analysis showed that the probability of treatment with mechanical thrombectomy plus intravenous thrombolysis being cost-effective was 57.5%, 89.7% and 99.6% at thresholds of $20 000, $50 000 and $100 000 per QALY gained, respectively. The main factors influencing the ICER were time horizon, extra cost of mechanical thrombectomy treatment and age of the patient. INTERPRETATION: Mechanical thrombectomy as an adjunct therapy to intravenous thrombolysis is cost-effective compared with treatment with intravenous thrombolysis alone for patients with acute large-artery ischemic stroke.

Research to practice: nursing stroke assessment guidelines link to clinical performance indicators.

Stroke is the fourth leading cause of death in Canada and, each year, approximately 50,000 Canadians will suffer a stroke with a range of severities from mild, short duration symptoms to significant long-term disability or death. Of these 50,000 patients, at least 20,000 are hospitalized. Earlier this year, a core set of evidence-based performance indicators were identified by a national consensus panel that may be used to determine the quality of care provided to stroke patients in hospital during the acute phase of illness. Nurses play a critical role in stroke care across the continuum and recently published stroke assessment guidelines for nurses clearly describe key approaches to assessment and/or screening of stroke survivors. Many of the nursing assessments and/or screening actions recommended in the guidelines have direct or indirect associations with the recent performance indicators. This article describes where those relationships exist and the role nurses may play in determining overall performance for acute stroke patient care delivery during the hospitalization phase of the stroke continuum of care.

Best practices in stroke care.

In 2001, the Ontario Ministry of Health and Long-Term Care introduced the Ontario Stroke Strategy by designating regional stroke centres across the province. The primary role of these centres is to coordinate stroke care within the region and across the care continuum in keeping with best practices. Concurrently, Trillium Health Centre was identifying best practice projects to support its ongoing quest for excellence. With Trillium designated as a regional stroke centre, acute ischemic stroke care was an obvious choice for a best practice project. The aim of the project was to improve access to care and quality of care for stroke patients from emergency through acute care to in-patient rehabilitation. The team chose the rapid cycle change methodology. This approach to quality improvement advocates the testing of a series of small changes (i.e., process improvement ideas) in tandem with measurements to assess the impact of the change to drive further process improvements. The project was deemed a success, resulting in significant improvements in the timeliness and quality of care.

Stroke rehabilitation and patients with multimorbidity: a scoping review protocol.

Stroke care presents unique challenges for clinicians, as most strokes occur in the context of other medical diagnoses. An assessment of capacity for implementing "best practice" stroke care found clinicians reporting a strong need for training specific to patient/system complexity and multimorbidity. With mounting patient complexity, there is pressure to implement new models of healthcare delivery for both quality and financial sustainability. Policy makers and administrators are turning to clinical practice guidelines to support decision-making and resource allocation. Stroke rehabilitation programs across Canada are being transformed to better align with the Canadian Stroke Strategy's Stroke Best Practice Recommendations. The recommendations provide a framework to facilitate the adoption of evidence-based best practices in stroke across the continuum of care. However, given the increasing and emerging complexity of patients with stroke in terms of multimorbidity, the evidence supporting clinical practice guidelines may not align with the current patient population. To evaluate this, electronic databases and gray literature will be searched, including published or unpublished studies of quantitative, qualitative or mixed-methods research designs. Team members will screen the literature and abstract the data. Results will present a numerical account of the amount, type, and distribution of the studies included and a thematic analysis and concept map of the results. This review represents the first attempt to map the available literature on stroke rehabilitation and multimorbidity, and identify gaps in the existing research. The results will be relevant for knowledge users concerned with stroke rehabilitation by expanding the understanding of the current evidence.

Nurses' accountability for stroke quality of care: part one: Review of the literature on nursing-sensitive patient outcomes.

Over the past decade, an exciting area of research has emerged that demonstrates strong links between specific nursing care activities and patient outcomes. This body of research has resulted in the identification of a set of "nursing-sensitive outcomes"(NSOs). These NSOs may be interpreted with more meaning when they are linked to evidence-based best practice guidelines, which provide a structured means of ensuring care is consistent among all health care team members, across geographic locations, and across care settings. Uptake of evidence-based best practices at the point of care has been shown to have a measurable positive impact on processes of care and patient outcomes. The purpose of this paper is to present a systematic, narrative review of the literature regarding the clinical effectiveness of nursing management strategies on stroke patient outcomes sensitive to nursing interventions. Subsequent investigation will explore current applications of nursing-sensitive outcomes to patients with stroke, and identify and validate measurable NSOs within stroke care delivery.
