Seeing the Gap: How Digital Gaps Shape Health Inequality

Digital exclusion isn’t just about lacking a smartphone. It’s a mix of personal habits, tech tools, the way institutions work, and big social forces. Think of it as many layers that affect who can go online and who can’t. When people can’t use digital health tools, they often end up with worse health outcomes. This gap can widen existing health inequalities.

The pandemic pushed health, welfare, and public services online fast. Researchers started looking at how this digital shift created new gaps. Even though studies on digital exclusion have exploded, the ideas about what it really means are still all over the place. That makes it hard to see a clear picture of how these gaps affect health.

Researchers searched PubMed, Scopus and other databases for papers published between January 2020 and July 2025. They used keyword searches and snowballing to collect more studies. Each article was read repeatedly, notes were made, and the team compared how different fields described digital exclusion and its link to health inequality. Users of the knowledge helped keep the interpretations useful for policy and practice.

The review shows that digital exclusion is seen in many ways, but the meanings clash across disciplines. Some view it as a tech problem, others as a social or policy issue. This mix makes it tough to link digital gaps directly to health disparities. Better, shared definitions could help design fairer health services for everyone.
