Transitional Health: Bridging Care, Systems, and Global Change

Abstract

Transitional health is a complex concept describing not only the modifications in population health patterns but also the transitions that occur in the health process of each individual over a life course. It addresses the epidemiologic, demographic, and nutrition transitions at large-scale levels, whereas it concerns the fundamental transitions in healthcare provision such as the switch between pediatric and adult care, between hospital and community-based care, and between acute and chronic disease treatment. In the 21st century, transitional health is increasingly becoming an important concept as health systems around the world have to grapple with the twin challenges of endemics, on the one hand, and, on the other hand, the rising prevalence of non-communicable chronic diseases. Additionally, transitional health structures place special focus on equity, continuity, and sustainability in delivering health services, particularly in resource-constrained settings. This article discusses the evolution, determinants, structures, and applications of transitional health, examines global case studies, and identifies challenges and directions for the future. Through the synthesis of theoretical models and pragmatic strategies, transitional health offers a critical framework in which policymakers, clinicians, and researchers can conceptualize and enhance population health outcomes within environments in the midst of rapid change.
