Yet another Bradford's law: new evidence on integrated care from Japan

In this edition of IJIC, a bibliometric study of academic journals in the field of integrated care quoted the “Bradford’s law”: a skewed concentration of academic articles in “core” journals [1]. The article also demonstrated yet another Bradford’s law: a skewed concentration of articles in a small number of countries with little relevance to population size. In particular, the distribution of evidence is heavily skewed towards articles from the USA and Northern Europe. In contrast, China and India, each occupying 19.5% and 17.8% of the world population, represent only 0.2% and 0.4% of publications, respectively, despite their recent focus on policies for developing primary and community-based integrated care.
