Using a Virtual Community of Practice to Support Stroke Best Practice Implementation: Mixed Methods Evaluation.

BACKGROUND: Successful best practice implementation is influenced by access to peer support and knowledge exchange. The Toronto Stroke Networks Virtual Community of Practice, a secure social media platform, is a knowledge translation tool supporting dissemination and adoption of stroke best practices for interprofessional stroke stakeholders. OBJECTIVE: The aim of this study is to evaluate the use of a virtual community of practice (VCoP) in supporting regional stroke care best practice implementation in an urban context. METHODS: A mixed methods approach was used. Qualitative data were collected through focus groups and interviews with stroke care provider members of the VCoP working in acute and rehabilitation settings. Thematic analysis was completed, and the Wenger Value Creation Model and developmental evaluation were used to reflect practice change. Quantitative data were collected and analyzed using website analytics on VCoP use. RESULTS: A year after implementation, the VCoP had 379 members. Analysis of web analytics data and transcripts from focus groups and interviews conducted with 26 VCoP members indicated that the VCoP provided immediate value in supporting user networking, community activities, and interactions. Skill acquisition and changes in perspective acquired through discussion and project work on the VCoP were valued by members, with potential value for supporting practice change. Learning about new stroke best practices through the VCoP was a starting point for individuals and teams to contemplate change. CONCLUSIONS: These findings suggest that the VCoP supports the early stages of practice change and stroke best practice implementation. Future research should examine how VCoPs can support higher levels of value creation for implementing stroke best practices.

Lessons learned and functional outcomes following multifaceted team training in a cognitive strategy-based approach to stroke rehabilitation.

AIM: To estimate the impact of a multifaceted knowledge translation intervention on patient rehabilitation outcomes in an inpatient stroke setting. METHODS: Interprofessional stroke rehabilitation teams were trained in Cognitive Orientation to daily Occupational Performance as part of the larger knowledge translation study. This study describes a two group (historical control vs. post knowledge translation intervention) nonrandomized study. Patient participants with stroke and cognitive impairment were recruited from five rehabilitation hospitals and completed an assessment battery upon admission to and discharge from rehabilitation and at three follow-up times. Data were analyzed using a two-way ANOVA. RESULTS: Seventeen historical controls and eight postintervention participants were recruited. The effect for time was significant (P ≤ 0.05) for the majority of outcomes, but there were no significant group × time effects. Small effect sizes for the group × time interaction were noted on several indicators. CONCLUSION: Few studies report on patient outcomes following a knowledge translation intervention. Small effect sizes were detected on several patient outcomes, despite study limitations. Lessons learned for future patient-level studies within knowledge translation interventions include the importance of monitoring therapist adherence to implementation protocols and ensuring research designs consider the impact on patient recruitment and retention.

The implications of the Canadian Stroke Best Practice Recommendations for design and allocation of rehabilitation after hospital discharge: a problematization.

Introduction: Implementation of the Canadian Stroke Best Practice Recommendations has improved inpatient rehabilitation. As attention is turned to the design and allocation of rehabilitation after hospitalization, examination of their implications for post-discharge rehabilitation could help optimize service planningMethods: Critical discourse analysis modeled on Alvesson and Sandberg's method of problematization was conducted to determine how the Canadian Stroke Best Practice Recommendations envision and shape post-discharge rehabilitation, and identify any tensions and potential ways to resolve them.Results: Within the Canadian Stroke Best Practice Recommendations post-discharge rehabilitation is implicitly viewed as a continuation of inpatient rehabilitation. Rehabilitation is largely envisioned as a set of biomedical procedures aimed at normalization through correction of impairment. There is potential tension between this implicit goal and the explicit goal of providing patient and family-centered care and promoting reengagement in valued activities and roles.Conclusion: An alternate vision of post-discharge rehabilitation could help resolve this tension. Post-discharge rehabilitation could be envisioned as a self-management intervention. Rather than primarily an expert-driven process of measuring impairment and applying procedures aimed at normalization, rehabilitation would be considered facilitation of self-management with the goal of reengaging in forms of participation that comprise a satisfying life.Implications for RehabilitationImplicit assumptions within best practice guidelines powerfully influence recommendations. These ideas are difficult to examine because they seem self-evident.Implicit assumptions in the Canadian Stroke Best Practice Guidelines envision post-discharge stroke rehabilitation as an expert-driven, impairment-focused biomedical procedure.This biomedical image makes it difficult to provide care that meets the guideline's explicit goals of client- and family-centeredness.Reimagining post-discharge stroke rehabilitation as a chronic self-care management intervention aimed at developing a satisfying life after stroke could improve patient care.

Implementing a function-based cognitive strategy intervention within inter-professional stroke rehabilitation teams: Changes in provider knowledge, self-efficacy and practice.

BACKGROUND: The Cognitive Orientation to daily Occupational Performance (CO-OP) approach is a complex rehabilitation intervention in which clients are taught to use problem-solving cognitive strategies to acquire personally-meaningful functional skills, and health care providers are required to shift control regarding treatment goals and intervention strategies to their clients. A multi-faceted, supported, knowledge translation (KT) initiative was targeted at the implementation of CO-OP in inpatient stroke rehabilitation teams at five freestanding rehabilitation hospitals. The study objective was to estimate changes in rehabilitation clinicians' knowledge, self-efficacy, and practice related to implementing CO-OP. METHODS: A single arm pre-post and 6-month follow up study was conducted. CO-OP KT consisted of a 2-day workshop, 4 months of implementation support, a consolidation session, and infrastructure support. In addition, a sustainability plan was implemented. Consistent with CO-OP principles, teams were given control over specific implementation goals and strategies. Multiple choice questions (MCQ) were used to assess knowledge. A self-efficacy questionnaire with 3 subscales (Promoting Cognitive Strategy Use, PCSU; Client-Focused Therapy, CFT; Top-Down Assessment and Treatment, TDAT) was developed for the study. Medical record audits were used to investigate practice change. Data analysis for knowledge and self-efficacy utilized mixed effects models. Medical record audits were analyzed with frequency counts and chi-squares. RESULTS: Sixty-five health care providers consisting mainly of occupational and physical therapists entered the study. Mixed effects models revealed intervention effects for MCQs, CFT, and PCSU at post intervention and follow-up, but no effect on TDAT. No charts showed any evidence of CO-OP use at baseline, compared to 8/40 (20%) post intervention. Post intervention there was a trend towards reduction in impairment goals and significantly more component goals were set (z = 2.7, p = .007).

A multi-faceted knowledge translation approach to support persons with stroke and cognitive impairment: evaluation protocol.

BACKGROUND: Patients with cognitive impairments following a stroke are often denied access to inpatient rehabilitation. The few patients with cognitive impairment admitted to rehabilitation generally receive services based on outdated impairment-reduction models, rather than recommended function-based approaches. Both reduced access to rehabilitation and the knowledge-to-practice gap stem from a reported lack of skills and knowledge regarding cognitive rehabilitation on the part of inpatient rehabilitation team members. To address these issues, a multi-faceted knowledge translation (KT) initiative will be implemented and evaluated. It will be targeted specifically at the inter-professional application of the cognitive orientation to daily occupational performance (CO-OP). CO-OP training combined with KT support is called CO-OP KT. The long-term objective of CO-OP KT is to optimize functional outcomes for individuals with stroke and cognitive impairments. Three research questions are posed: 1. Is the implementation of CO-OP KT associated with a change in the proportion of patients with cognitive impairment following a stroke accepted to inpatient rehabilitation? 2. Is the implementation of CO-OP KT associated with a change in rehabilitation clinicians' practice, knowledge, and self-efficacy related to implementing the CO-OP approach, immediately following and 1 year later? 3. Is CO-OP KT associated with changes in activity, participation, and self-efficacy to perform daily activities in patients with cognitive impairment following stroke at discharge from inpatient rehabilitation and at 1-, 3-, and 6-month follow-ups? METHODS/DESIGN: Three interrelated studies will be conducted. Study 1 will be a quasi-experimental, interrupted time series design measuring monthly summaries of stroke unit level data. Study 2, which relates to changes in health care professional practice and self-efficacy, will be a single group pre-post evaluation design incorporating chart audits and a self-report survey. Study 3 will assess patient functional outcomes using a non-randomized design with historical controls. Assessments will occur during admission and discharge from rehabilitation and at 1, 3, and 6 months following discharge from rehabilitation. DISCUSSION: This project will advance knowledge about the degree to which the implementation of a supported KT initiative can sustainably change health system, knowledge, and patient outcomes.

Cortical responses associated with predictable and unpredictable compensatory balance reactions.

This study investigated the effects of postural set on the cortical response evoked by an external perturbation to human upright stance. Postural set was manipulated by providing either predictable or unpredictable whole body perturbations which required balance corrections to maintain upright stability. Unpredictable perturbations evoked a large negative potential (e.g., CZ: -19.9+/-5.1 microV) that was similar in timing (e.g., CZ: 98.9+/-5.5 ms) and shape to that reported in previous studies. This large negative potential was not discernable for perturbations with predictable onset timing and direction in spite of the presence of significant compensatory balance reactions. Importantly, when a surprise perturbation was presented following a series of predictable perturbations, the large negative potential occurred on this trial even though subjects expected a predictable stimulus onset. This suggests that the large negative potential was dependent on a dissociation between expected and actual stimuli rather than on a tonic central state defined by task conditions. These results suggest that cortical events may be linked to error detection that is independent of sensory or motor events associated with evoked balance reactions.

The association between later cortical potentials and later phases of postural reactions evoked by perturbations to upright stance.

Previous studies have suggested that early cortical potentials (e.g. N1) that are evoked by perturbations to upright stance are associated with sensory processing of the initial perturbation and that later potentials may represent cognitive processing of this perturbation. However, it has also been suggested that later cortical potentials could reflect sensory and motor processing of later phases of the postural reaction. The current study set out to provide additional insight into the association between perturbation-evoked cortical potentials and postural reactions evoked by whole-body perturbations. By altering the deceleration onset of the perturbation, which altered the timing of later postural responses, we determined whether changes in later postural responses were associated with changes in later potentials. Based on previous work, we hypothesized that later potentials would not be associated with changes in later postural responses. During stance, seven healthy young adults were instructed to maintain their balance following two types of perturbations: (1) acceleration phase immediately followed by a deceleration phase (TASK 1), and (2) acceleration phase followed by a delayed deceleration phase (TASK 2). In spite of profound task differences in later postural responses, results revealed no significant differences in later potentials. This work provides additional support for the idea that latter elements of perturbation-evoked cortical responses are likely independent of evoked motor reactions required to maintain stability.

The effect of a concurrent cognitive task on cortical potentials evoked by unpredictable balance perturbations.

BACKGROUND: Although previous studies suggest that postural control requires attention and other cognitive resources, the central mechanisms responsible for this relationship remain unclear. To address this issue, we examined the effects of altered attention on cortical activity and postural responses following mechanical perturbations to upright stance. We hypothesized that cortical activity would be attenuated but not delayed when mechanical perturbations were applied during a concurrent performance of a cognitive task (i.e. when attention was directed away from the perturbation). We also hypothesized that these cortical changes would be accompanied by alterations in the postural response, as evidenced by increases in the magnitude of anteroposterior (AP) centre of pressure (COP) peak displacements and tibialis anterior (TA) muscle activity. Healthy young adults (n = 7) were instructed to continuously track (cognitive task) or not track (control task) a randomly moving visual target using a hand-held joystick. During each of these conditions, unpredictable translations of a moving floor evoked cortical and postural responses. Scalp-recorded cortical activity, COP, and TA electromyographic (EMG) measures were collected. RESULTS: Results revealed a significant decrease in the magnitude of early cortical activity (the N1 response, the first negative peak after perturbation onset) during the tracking task compared to the control condition. More pronounced AP COP peak displacements and EMG magnitudes were also observed for the tracking task and were possibly related to changes in the N1 response. CONCLUSION: Based on previous notions that the N1 response represents sensory processing of the balance disturbance, we suggest that the attenuation of the N1 response is an important central mechanism that may provide insight into the relationship between attention and postural control.
