Brief summary: After stroke, individuals must be assessed to determine if they can resume driving. Return to driving is very important to people who have experienced a stroke. Unfortunately, health care providers face challenges in addressing driving after stroke. Common issues include being unsure of the best screening practices, difficulty discussing driving with patients, and challenges making informed recommendations about driving that balance the risk of public safety along with supporting patient goals. Occupational Therapists (OTs) are health care providers that provide screening, assessment, and intervention for driving to individuals who have had a stroke. OTs working in stroke care have highlighted the urgency for evidence-based resources to support practice to address driving with patients. The Practice Resource for Driving After Stroke (PReDAS), is an evidenced-based resource to support the clinical practice of OTs in addressing driving in acute stroke settings. A previous pilot study has demonstrated that the PReDAS is considered useful by both health care providers and patients. Further study is needed to evaluate how the PReDAS can support OTs in addressing driving with patients. The current study proposes to provide the PReDAS as an intervention to OTs working in acute stroke settings to see if the intervention increases OT's self efficacy and clinical reasoning for addressing driving. The study will take repeated measures of self-efficacy and clinical reasoning among participating OTs to determine if the PReDAS intervention supports improved self-efficacy and clinical reasoning.

Detailed description: Background Negotiating return to driving after stroke is a complex process for both clients and health professionals. In many jurisdictions worldwide, there is a mandatory period of driving restriction post-stroke and driving can only be resumed when functional assessments reveal no residual functional impairments that would impact driving ability, including within Canada. Clients experience considerable practical and symbolic challenges when driving status is questioned and community mobility is threatened. Health care providers, including occupational therapists, similarly feel ill-equipped to broach the contentious topic of driving with their clients. As such, extant literature has identified the need for context-specific practice resources for health professionals to navigate the difficult return to driving process with clients following stroke. In response, the Practice Resource for Driving After Stroke (PReDAS) was developed to provide occupational therapists with a comprehensive, stroke-specific, evidence-based resource to inform clinical reasoning for addressing driving in the acute care setting, where initial discussions about driving take place following stroke.

The PReDAS, informed by the Canadian Stroke Best Practice guidelines, includes resources and procedures for 5 key elements including: (1) best practice education for the practitioner, (2) fitness to drive screening, (3), clinical decision-making aids, (4) stakeholder communication and (5) community mobility planning. The PReDAS is not a screening tool, but rather a practice resource for clinicians to address driving post-stroke within the acute care context. The PReDAS aims to guide the practitioner through the process of addressing driving from initial conversations with the client to communicating recommendations. In a recent pilot study, occupational therapists and physicians reported the PReDAS provided a clear and consistent process for addressing driving, enhanced communication and collaboration with the team and patient, and supported clinical decision-making for driving recommendations. Patients similarly agreed the PReDAS was a useful resource to address driving and supported their own decisions surrounding returning to driving. The pilot findings support the need for further evaluation of the PReDAS to support the practice of occupational therapists in addressing driving with clients after stroke.

The goal of the proposed study is to examine the effects of the PReDAS on the clinical reasoning and self-efficacy of occupational therapists to address driving in acute stroke settings. Bandura defines self-efficacy as "beliefs in one's capabilities to organize and execute the courses of action required to produce given attainments". Clinical reasoning is defined as a "complex cognitive process that uses formal and informal thinking strategies to gather and analyze patient information, evaluate the significance of this information and weigh alternative actions".

Methods Design A concurrent multiple-baseline design will be utilized to examine the effects of the PReDAS on clinical reasoning and self-efficacy for addressing driving in acute stroke settings among occupational therapists. While this approach includes a smaller sample size, this design will enable detailed, rich data collection from a smaller, engaged group of participants. Occupational therapists in acute care report driving is important to their practice, but consistently report time constraints in their work, which would likely extend to limited time for research participation as well. As such, a randomized controlled trial design requiring many participants to have sufficient statistical power, would be unrealistic given the characteristics of the target population. Moreover, as constructs such as self-efficacy and clinical reasoning may be dynamic, repeated measures as achieved in a multiple baseline design can demonstrate how constructs change over time.

Participants Eight occupational therapists will be recruited through a variety of methods, including online invitations via social media platforms (Facebook, Twitter), professional networks (Clinical Preceptor Network from Western University, Greater Toronto Area Occupational Therapy Professional Practice Leader Network), and professional associations (Canadian Association of Occupational Therapists and Ontario Society of Occupational Therapists, and Provincial Stroke Networks). Occupational therapists are eligible to participate if they currently practice on an acute stroke unit. To avoid threats to treatment fidelity, occupational therapists are ineligible to participate if there is already a participant enrolled from their local workplace (same physical building), or if they have viewed a copy of the PReDAS previously. Invitations to participate will be shared via social media posts and email. The letter of information and consent from will be provided electronically via QualtricsXM, which will direct prospective participants to provide their email address for communication throughout the study.

PReDAS Intervention To ensure each participant receives the same exposure and training for the PReDAS, each occupational therapist will participate in a 1:1 standardized 1-hour training session. A brief multiple-choice knowledge test will be administered to each participant after the training session to evaluate understanding of the material. Training sessions will occur online via Zoom. Participants will also receive a full-text electronic copy of the PReDAS for use and reference throughout the study.

Instruments Self-efficacy will be measured by the Personal Efficacy and Beliefs Scale (PEBS) which measures self-efficacy regarding work-related skills and tasks. Internal reliability is estimated at .82 from a sample of nurses working in acute care. The validity of the PEBS is supported through positive correlations with similar measures of satisfaction, job performance and organizational commitment. Clinical reasoning will be measured by the Self-Assessment of Clinical Reflection and Reasoning (SACRR) developed to evaluate clinical reasoning among occupational therapists and physiotherapists. Internal consistency has been rated between .87 and .92 as measured by Cronbach's Alpha, and Spearman rank order correlation coefficient for test-retest reliability is rated as "acceptable" at .60.

As the PEBS and SACRR are broad measures of job self-efficacy and clinical reasoning and reflection respectively, the measures were slightly adapted to cue the participants to answer the questions specific to addressing driving in their practice. For example, instead of the following item from the PEBS "I have confidence in my ability to do my job", the item was adapted to "I have confidence in my ability to address driving". As with the PEBS, participants will be cued to answer the SACRR it relates to addressing driving in acute care settings. The adapted PEBS and SACRR surveys are presented in Appendix A and B, respectively.

Demographic data will also be collected including (1) email, (2) first and last name, (3) year of graduation from occupational therapy program, and (4) number of years working in acute stroke settings.

Procedure Design standards for multiple-baseline studies recommend at least three A-B tiers and at least 5 data points. As such, the proposed study will aim to recruit eight occupational therapists and obtain seven data collection points, to accommodate for attrition and exceed minimum standards. Data will be collected for a period of 6 months with data collected at seven points: at baseline, 1,2,3,4, 5 and 6 months. The criterion for introduction of the PReDAS intervention to participants will be determined by number of months from baseline, whereby each participant will be randomly assigned to receive the PReDAS at month 2, 3, 4, or 5, ensuring there is at least one participant in each time frame.

The platform QualtricsXM will be used for consent and data collection. Participants will be emailed an online survey link to review the letter of information and express consent to participate in the study. After indicating consent, participants will be automatically re-directed to a separate demographic survey where participants will generate a unique participant ID. At the required seven data collection timepoints, participants will be contacted via email to complete the PEBS and SACRR and enter their unique participant ID. As the demographic survey that connects the participant's name to their participant ID is separate from the data collection survey, the timing of when each participant received the PReDAS intervention will not be known until data analysis is complete to reduce risk of bias.

Analysis Visual analysis involves systematic procedures to assess patterns and relationships in graphed data from multiple baseline designs. Visual analysis facilitates examination of the efficacy of the intervention across time and subjects and is critical for assessing experimental control. As such, visual analysis will be utilized to evaluate changes in (1) clinical reasoning and self-efficacy both within participants and across participants, and (2) observe the relationship between the introduction of the PReDAS and occupational therapist reported clinical reasoning and self-efficacy.

Tau-U analysis is a widely accepted statistical procedure within single subject designs that: can control for Type I errors, adjust for baseline trend, is less affected by within-case variability, correlates well with other indices (such as visual analysis), and discriminates well at upper and lower limits. Tau-U analyses will be conducted to evaluate the effect size of the PReDAS using the conventions of small (\<.20), moderate (.20-0.60), large (0.60-0.80) or very large (\>0.80).

Expected Results and Knowledge Mobilization The results of the proposed study will provide further evidence for the use of the PReDAS as a resource to occupational therapists in acute care for addressing driving. This is an important next step to establish the PReDAS as evidence-based resource for occupational therapists in acute stroke settings. Moreover, as the study will employ a multiple baseline design, the findings will not only reveal if the introduction of the PReDAS improves clinical reasoning or self-efficacy but will also permit examination of how these constructs may change over time. A manuscript will be prepared to submit to OTJR: Occupational Therapy Journal of Research to disseminate findings. To reach practicing therapists, a presentation will be submitted to two annual occupational therapy conferences, the Canadian Association of Occupational Therapy (CAOT)\] and American Association of Occupational Therapy (AJOT), and a webinar proposal will be submitted to CAOT.
