Utilizing Implementation Science to Bridge Cerebrovascular Health Disparities: a Local to Global Perspective.

Abstract

Stroke is a prime example of a medical disorder whose incidence, prevalence, and outcomes are strongly characterized by health disparities across the globe. This scoping literature review seeks to depict how implementation science could be utilized to advance health equity in the prevention, acute treatment, and post-acute management of stroke in the underserved regions of high-income countries as well as in all low-income countries. A major reason for the persisting and widening cerebrovascular disease disparities is that evidence-based stroke prevention and treatment interventions have been differentially translated (if at all) to various populations and settings. The field of implementation science is endowed with frameworks, theories, methodological approaches, and outcome measures, including equity indices, which could be harnessed to facilitate the translation of evidence-based interventions into clinical practice for underserved and vulnerable communities. Encouragingly, there are several novel frameworks, which eminently merge implementation science constructs with health equity determinants, thereby opening up key opportunities to bridge burgeoning worldwide gaps in cerebrovascular health equity.
