    Stroke Learning Health Systems: A Topical Narrative Review With Case Examples
    (American Heart Association, 2023) Cadilhac, Dominique A.; Bravata, Dawn M.; Bettger, Janet Prvu; Mikulik, Robert; Norrving, Bo; Uvere, Ezinne O.; Owolabi, Mayowa; Ranta, Annemarei; Kilkenny, Monique F.; Medicine, School of Medicine
    To our knowledge, the adoption of Learning Health System (LHS) concepts or approaches for improving stroke care, patient outcomes, and value have not previously been summarized. This topical review provides a summary of the published evidence about LHSs applied to stroke, and case examples applied to different aspects of stroke care from high and low-to-middle income countries. Our attempt to systematically identify the relevant literature and obtain real-world examples demonstrated the dissemination gaps, the lack of learning and action for many of the related LHS concepts across the continuum of care but also elucidated the opportunity for continued dialogue on how to study and scale LHS advances. In the field of stroke, we found only a few published examples of LHSs and health systems globally implementing some selected LHS concepts, but the term is not common. A major barrier to identifying relevant LHS examples in stroke may be the lack of an agreed taxonomy or terminology for classification. We acknowledge that health service delivery settings that leverage many of the LHS concepts do so operationally and the lessons learned are not shared in peer-reviewed literature. It is likely that this topical review will further stimulate the stroke community to disseminate related activities and use keywords such as learning health system so that the evidence base can be more readily identified.

    Vascular-brain Injury Progression after Stroke (VIPS) Study: concept for understanding racial and geographic determinants of cognitive decline after stroke
    (Elsevier, 2020) Sarfo, Fred Stephen; Akinyemi, Rufus; Howard, George; Howard, Virginia J.; Wahab, Kolawole; Cushman, Mary; Levine, Deborah A.; Ogunniyi, Adesola; Unverzagt, Fred; Owolabi, Mayowa; Ovbiagele, Bruce; Psychiatry, School of Medicine
    Cognitive impairment and dementia (CID) are major public health problems with substantial personal, social, and financial burdens. African Americans are at a heightened risk for Vascular Cognitive Impairment (VCI) compared to European Americans. Recent lines of evidence also suggest a high burden of Post-stroke VCI among indigenous Africans. A better understanding of the cause(s) of the racial disparity in CID, specifically VCI, is needed in order to develop strategies to reduce it. We propose and discuss the conceptual framework for a unique tri-population, trans-continental study titled The Vascular brain Injury Progression after Stroke (VIPS) study. The overarching objective of the VIPS Study will be to explore the interplay of multiple factors (racial, geographical, vascular, lifestyle, nutritional, psychosocial and inflammatory) influencing the level and trajectory of post-stroke cognitive outcomes and examine whether differences between indigenous Africans, African Americans and European Americans exist. We hypothesize that differences which might be due to racial factors will be observed in African Americans versus European Americans as well as Indigenous Africans versus European Americans but not in African Americans versus Indigenous Americans; differences due to geographical factors will be observed in Indigenous Americans versus African Americans and Indigenous Africans versus European Americans but not in African Americans versus European Americans. This overarching objective could be accomplished by building upon existing National Institutes of Health investments in the REasons for Geographical And Racial Differences in Stroke (REGARDS) study (based in the United States of America) and the Stroke Investigative Research and educational Network (SIREN) study (based in Sub-Saharan Africa).
