Networks of collaborating organizations have become critical mechanisms for the effective delivery of healthcare and related human services. Despite their importance, there is much about health networks that is not understood. The article by Huerta, Casebeer and VanderPlaat is an effort to discuss the importance of health services delivery networks and to point out ways in which such networks might best be studied. Their article offers a number of useful and interesting ideas for both practice and research. Many of these ideas are not, however, well organized, integrated or fully developed. This commentary provides a critique of their work, while offering some of our own suggestions about how the study of health delivery networks might be advanced.
