Preventing and Managing Cognitive Impairment

Study Overview
=================
Brief Summary
-----------------
This randomized controlled trial (RCT) is used to address the knowledge translation of primary care practitioners (PCPs) for the early identification of cognitive impairment. Cognitive impairment is experienced by people with many different underlying health problems, e.g., diabetes, cardiovascular problems, COVID-19, neurodegenerative diseases, and mental health problems. Older adults are more likely to have cognitive decline which may develop into Alzheimer's disease or dementia but 40% of dementia can be prevented by managing the risks. Cognitive impairment can demand vast societal resources, the burden is reported to be more among Hispanics and blacks. By 2029, all baby boomers will be over 65, comprising at least 20% of the U.S. population. So, it is critical for PCPs to effectively identify, prevent, and manage the hidden signs of cognitive impairment. People with early signs of cognitive impairment will have opportunities to benefit from suitable cognitive remediation to reverse it or prevent rapid progression. It is critically important for people who are socioeconomically disadvantaged, those who are black, indigenous, and people of color (BIPoC). These people are often served by safety-net hospitals, such as clinics of the Los Angeles County (LAC) Department of Health Services and the federally qualified health centers at the Community Clinics Association of LAC. Many PCPs in these clinics are often BIPoC. The intervention used in this RCT is called Cognition ECHO based on the proven model of ECHO (Extension of Healthcare Outcomes) for knowledge dissemination and translation. Cognition ECHO is a virtual activity incorporating a short didactic presentation and de-identified case discussion to solve real-world patient care challenges and ease direct knowledge translation. PCPs in the LAC will be randomized into Groups 1 and 2. Group 1 will attend the five Cognition ECHO for four months, Group 2 will be the control. Group 2 will attend Cognition ECHO starting on July 25, 2023, five times till November 7, 2023, when Group 1 is the follow-up. Most sessions are scheduled on the fourth Tuesday of the month with the addition of June 6 and November 7, 2023. Focusing on cognitive impairment and targeting PCPs at the LAC, the goal of this study is to evaluate if Cognition ECHO can improve PCPs' capacity to detect early cognitive impairment and manage it. It will result in opportunities to mitigate the risk factors of early cognitive impairment, especially for minority patients in LAC, and conduct efficacy studies in the future to address cognitive impairment focusing on BIPoC.

Design Details

Primary Purpose: Other
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Group 1 will receive the intervention Cognition ECHO during Phase 1 and Group 2 will serve as the control. About one month after Group 1 has completed the attendance of all five sessions of Cognition ECHO, Group 2 will start receiving the intervention Cognition ECHO and Group 1 will wait for the follow-up till Week 41 of the study in November 2023.
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Group 1<br>To receive intervention during the phase 1 and will receive nothing during the phase 2, will complete the measure at the end of phase 2 as the follow-up | Other: Cognition ECHO<br>* Cognition ECHO is the intervention designed to be used by the study participants who are primary care practitioners. No involvement of patients in this study. The panel will consist of the CI and Co-PIs of this study, a neurologist as a co-moderator, a medical specialist who is the expert on the subject, an occupational therapist, a psychologist, and a speech and language pathologist with experience and expertise in CI. A patient with CI and a caregiver, family member, or community representative who is not a healthcare professional will join the panel because CI is frequently observed with lived experience of family members and loved ones, as two non-clinician panelists. The five topics with the integration of related diagnoses for Cognition ECHO are listed in Table 4. The time allocated for the didactic will be 15-20 minutes and the de-identified case discussion will be 40 - 45 minutes.<br>* Other names: Tele-mentoring with (1) a didactic presentation and (2) de-identified discussion by a panel with experts, a patient, and a family member.;|
| No Intervention: Group 2<br>To serve as the control during phase 1 and receive intervention during the phase 2 | |

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The Self-Efficacy of Cognition Management Tasks - 1 | The Self-Efficacy of Cognition Management Tasks (CMTs) is a survey adapted from a self-efficacy scale for primary care practitioners to evaluate their self-efficacy in diabetes care provision (Bouchonville et al., 2018). The Self-Efficacy of CMTs measures the capacity of PCPs to do these cognition management tasks. It is a survey with ten items using a seven-point scale ranging from none, no skills to expert, teaching others. The final score ranges from 10 to 70 with a high score reflecting better self-efficacy. The items reflect the knowledge and skills most relevant to detecting and managing cognitive impairment by primary care practitioners. With the adjustment to address response shift bias, the retrospective pre-intervention status will be compared together. | The 2nd day of Week 22 to the end of Week 25 |

| Estimated adherence1 | The ETAC (Empowered-To-Act Consistently) scale is used to measure the estimated adherence. The categories are to guide learners' reflection on their future actions, not measuring change. Four ETAC questions are designed for the four cognition management tasks to be included in a post-session evaluation of a Cognition ECHO session. Using the ETAC scale, the reasons and concerns of the option selected can be explored qualitatively. The ETAC scale has six levels: A) I will not do it; because: _. B) I will think about it, because: _. C) I will think about ways to help me start doing it, specific areas: _ . D) I'll start doing it from now on, areas to start: _. E) I've done some but can still do more, areas to do more: _. F) I am doing it as much as I can. No new actions are needed; sharing your successful experience: _.
