Summary
“Policy” is inevitably “politics”– the use of power. What is so striking and instructive about the nurse‐midwifery studies is that so much has been accomplished by their use when the studies themselves are so few; the nurse‐midwives who benefit from the changes in policy are few as well; however, the changes in health care access are great. Granted, other forces are at work here, including the wisdom of the professional organization of nurse‐midwives in concentrating its agendas, the marriage of consumer and provider interests in humane experience in childbirth, the rise of feminism, the wish of patients and providers (nurse‐midwives) alike to control their own existence, the disenchantment of childbearing families with traditional patronizing obstetrical care, and so on. Many of these variables are not rational contributions to policy formulation. What is rational is the argument from data, and that is where the studies come in.
Yet what becomes clear in this review is that no amount of research will ever be enough. The intricate relationship of policy to politics shows through very clearly in the studies reviewed, and as the politics change (from “safety” as agenda to “cost effectiveness” or competition) more data will continue to be needed. Indeed public policy making is an eternal process.
Important as effectiveness studies are and have been, alone they could not possibly make or break the policy considerations nursing faces. Without studies of effect, however, nursing is left to argue on moral principle, right to practice, or naked power. With them, nursing may argue, as Fagin (1982b) has, that its services are “substitutive, not additive”, (p. 1849)
