Protocol for SYNchronising Exercises, Remedies in GaIt and Cognition at Home (SYNERGIC@Home): feasibility of a home-based double-blind randomised controlled trial to improve gait and cognition in individuals at risk for dementia.

INTRODUCTION: Physical exercise and cognitive training have the potential to enhance cognitive function and mobility in older adults at risk of Alzheimer's disease and related dementia (ADRD), but little is known about the feasibility of delivering multidomain interventions in home settings of older adults at risk of ADRD. This study aims to assess the feasibility of home-based delivery of exercise and cognitive interventions, and to evaluate the relationship between participants' intervention preferences and their subsequent adherence. Secondary objectives include the effect of the interventions on ADRD risk factors, including frailty, mobility, sleep, diet and psychological health. METHODS AND ANALYSIS: The SYNchronising Exercises, Remedies in GaIt and Cognition at Home (SYNERGIC@Home) feasibility trial is a randomised control trial that follows a 2×2 factorial design, with a 16-week home-based intervention programme (3 sessions per week) of physical exercises and cognitive training. Participants will be randomised in blocks of four to one of the following four arms: (1) combined exercise (aerobic and resistance)+cognitive training (NEUROPEAK); (2) combined exercise+control cognitive training (web searching); (3) control exercise (balance and toning)+cognitive training; and (4) control exercise+control cognitive training. SYNERGIC@Home will be implemented through video conferencing. Baseline and post-intervention assessments at 4-month and 10-month follow-up will include measures of cognition, frailty, mobility, sleep, diet and psychological health. Primary feasibility outcome is adherence to the interventions. Primary analytic outcome is the relationship between pre-allocation preference for a given intervention and subsequent adherence to the allocated intervention. A series of secondary analytic outcomes examining the potential effect of the individual and combined interventions on cognitive, mobility and general well-being will be measured at baseline and follow-up. ETHICS AND DISSEMINATION: Ethics approval was granted by the relevant research ethics boards. Findings of the study will be presented to stakeholders and published in peer-reviewed journals and at provincial, national and international conferences.

A collaborative intervention for deprescribing: The role of stakeholder and patient engagement.

BACKGROUND: At a recent World Café Workshop on future deprescribing priorities, Canadian researchers identified that, in addition to implementation evaluation and economic analyses, high quality clinical trials require meaningful patient engagement. OBJECTIVES: The aim was to develop a deprescribing intervention for collaborative primary healthcare clinics and long-term care facilities that have pharmacists integrated in these settings. This manuscript aims to provide a summary of the experience with engaging patients in the development of the deprescribing framework. METHODS: Sixteen members of the research team met with six patient representatives (identified by the Maritime SPOR SUPPORT Unit) in a facilitated meeting. The event provided a welcoming environment for all participants; discussion groups ensured a mix of clinical, research and patient voice; and facilitators focused on engaging all voices equally. Initial discussions were structured around four topics: 1) identifying and prioritizing potentially inappropriate medications to reduce or stop; 2) identifying patients appropriate for deprescribing; 3) effectively communicating deprescribing with both patients and prescribers; and 4) measuring satisfaction with the framework. Subsequent discussions used group input to draft an intervention. After the event, participants engaged via e-mail, to refine the proposed intervention. RESULTS: The facilitated meeting provided helpful insight into patients' interests and changed the shape of the project. For example, patient representatives felt that an age restriction of 65 years of age or older was unfair, as deprescribing may help people younger than 65 years of age. Patient representatives also felt it was crucial to have resources to offer with non-pharmacologic information to increase success of deprescribing. This led to the deprescribing intervention becoming a framework for pharmacist-led deprescribing and a toolbox of supportive patient and healthcare professional resources. CONCLUSIONS: Overall, this process allowed for successful and meaningful patient engagement that aligned well with priorities for deprescribing clinical trials.

ULTRASIM: Ultrasound in trauma simulation.

OBJECTIVE: This study sought to assess the effectiveness of ultrasound simulation as a component of high-fidelity trauma simulation, in training diagnostic capabilities of resident and attending physicians participating in simulated trauma scenarios. METHODS: Twelve residents and 20 attending physicians participated in 114 trauma simulations. Participants generated a ranked differential diagnosis list after a physical exam and subsequently after a simulated extended focused assessment with sonography for trauma (E-FAST) ultrasound scan. We compared reports to determine whether the addition of ultrasound improved diagnostic performance. RESULTS: The primary diagnosis accuracy improved significantly with the addition of simulated ultrasound (p<0.0001). Median diagnostic ranking scores also improved (p<0.0001). Further, participants reported a higher confidence in their diagnoses (p<0.0001) and narrowed their differential diagnosis list (p<0.0001). CONCLUSION: We demonstrated that a low-cost ultrasound simulator can be successfully integrated into trauma simulations, resulting in an associated improvement in measures of diagnostic accuracy, confidence, and precision for participating resident and attending physicians.
