AOM Clinical Practice Guidelines

Since 1999, the AOM has produced evidence-based clinical practice guidelines (CPGs) consistent with the midwifery philosophy of care that reflect the values of the AOM, including informed choice, client as the primary decision-maker, choice of birthplace, and appropriate use of technology.

AOM CPGs are developed using the Values-Based Approach to CPG Development, a document that outlines the selection process for CPG topics, use of evidence, and development of recommendations.
