Bibliometric Analysis and Visualization of Catholic Health Care Research: 1973-2019.

A multi-dimensional construct of Catholic health care is examined using a bibliometric analysis of 181 scientific studies from the Web of Science database. Medical ethics, religion, and health services research by 418 authors from 26 countries reveals developments in the Catholic health care domain since 1973. Using VOSviewer, we map keyword clusters to reveal the structure of research on Catholic health care that transcends religious and secular literatures. The clusters mostly reflect clinical and ethical issues of reproductive health and the end of life, as well as the essence and the future of the Catholic identity from the theological and empirical perspectives.
