A Delphi survey was conducted with midwife scholars to determine the top 10 midwifery studies worthy of recognition in 2005, the 50th anniversary of the American College of Nurse-Midwives (ACNM). This survey was undertaken by students of Philadelphia University's Graduate Midwifery Program as a service-learning project on behalf of the ACNM Division of Research. Selected midwife scholars participated in 2 or 3 rounds of response and feedback to achieve consensus about research deemed historically or currently important to midwifery practice. The top 10 studies, as determined by the 19 participating midwife scholars, are presented here. These results are offered as reflection on research that has helped to shape and define the discipline of midwifery in the United States.
