The active and passive voice allocated to women within maternity service guidelines helps construct the nature of decision making. The aim of this paper is to demonstrate that by allocating women an active voice within practice guidelines serves the interest of all parties within the health care relationship. Clinical guidelines were reviewed, and electronic databases and text were searched. The findings of this paper support that applying the principles of a shared decision making framework, within clinical practice guidelines, can assist the development of a partnership relationship between midwives and women.
