Wide Spectrum Investigation of Stroke Outcome Disparities on Multiple Levels (WISSDOM) (CINGS)

Wide Spectrum Investigation of Stroke Outcome Disparities on Multiple Levels (WISSDOM): Community-based Intervention Under Nurse Guidance

This research project will evaluate the relationship between cardiovascular risk factors, degrees of physical and mental activity prior to the stroke, brain tissue integrity, post-stroke community participation and neurological recovery after the stroke. Investigators will recruit and study healthy and post stroke participants, gaining insight into the possible mechanisms that explain why the adverse risk profile, which is more commonly present in African-Americans than non-Hispanic Whites in the stroke belt, is translated into a less favorable recovery post stroke.

Study Overview

• Status: Completed
• Conditions: Minority Health; Stroke Ischemic
• Intervention / Treatment: Behavioral: Community-based Intervention under Nurse Guidance after Stroke

Detailed Description

Stroke is a common cause of disability, but not all subjects who survive a stroke are left with debilitating sequelae. The human brain is able to self-repair and adapt after injury through neuroplasticity, which is crucial for stroke recovery. At present, recovery cannot be completely predicted from clinical stroke variables. A promising theory suggests that the health status of the stroke host is as important as stroke severity for recovery. Within the neurological system, health is reflected by the integrity of the brain tissue and its neuronal environment, which provide the neuroplastic potential that is necessary for recovery. The potential for neuroplasticity is likely variable across individuals and possibly accounts for some of the differences in outcome that cannot be explained by other clinical factors.

A better understanding of the relationship between stroke outcomes, host brain tissue integrity and recovery environment would have immense potential to address stroke related disabilities. The investigators are experts in research involving brain tissue integrity using neuroimaging and recovery environment using community based participation approaches involving nurse-guided community health workers (CHWs).

This research project will evaluate the relationship between cardiovascular risk factors, degrees of physical and mental activity prior to the stroke, brain tissue integrity, post-stroke community participation and neurological recovery after the stroke. The investigators will recruit and study a biracial cohort, gaining insight into the possible mechanisms that explain why the adverse risk profile, which is more commonly present in African-Americans than non-Hispanic Whites in the stroke belt, is translated into a less favorable recovery post stroke. If a better understanding of the underlying reasons for this observation can be defined, an important first step toward eliminating this disparity can be achieved.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: CINGS Intervention; CINGS is a 12-week nurse coordinated, Community Health Worker (CHW) intervention structure. Registered Nurse (RN) developed After hospital care plan with home visits sessions will be conducted by the CHW and intermittent televideo RN interactions. After baseline assessment, participants randomized to the intervention group will have home visits, once a week for the first month, and biweekly during months two and three. follow up assessments at 3, 6, and 12-month intervals.	Behavioral: Community-based Intervention under Nurse Guidance after Stroke; CINGS is a 12-week nurse coordinated, Community Health Worker intervention structure. Intervention home visits will be conducted by the CHW and will include home-based training in self-care and self-management strategies alongside strategies to address risk of negative stroke outcomes that will be determined once these risk factors are identified and community-engaged approaches to their resolution derived. CHW efforts will be guided via televideo interactions with nurse coordinator. During home-visits, self-reported assessments will be collected via RedCap as well as assessments collected by the CHW and research nurse (weight, blood pressure, medication adherence). After baseline, participants randomized to the intervention group will have home visits, once a week for the first month, and biweekly for the other two months, conducted by the CHW. Additionally, there will be post-intervention follow-up assessments at 3, 6, and 12-month time intervals.; Other Names: CINGS
Experimental: Control; Control group will receive usual care. Base line visit and follow up at 3, 6, and 12 months post stroke enrollment.
