The American College of Obstetricians and Gynecologists (ACOG) and the American College of NurseMidwives (ACNM) affirm our shared goal of safe women’s health care in the United States through the promotion of evidence-based models provided by obstetricians-gynecologists (ob-gyns), certified nurse-midwives (CNMs), and certified midwives (CMs). ACOG and ACNM believe health care is most effective when it occurs in a system that facilitates communication across care settings and among clinicians. Obgyns and CNMs/CMs are experts in their respective fields of practice and are educated, trained, and licensed independent clinicians who collaborate depending on the needs of their patients2.

These clinicians practice to the full extent of their education, training, experience, and licensure and support team-based care2, 3. ACOG and ACNM advocate for health care policies that ensure access to appropriate levels of care for all women4. Quality of care is enhanced by collegial relationships characterized by mutual respect and trust; professional responsibility and accountability; and national uniformity in full practice authority and licensure across all states. 

Shortages and maldistribution of maternity care clinicians cause serious public health concerns for women, children, and families5. Ob-gyns and CNMs/CMs working together optimize women’s health care. ACOG and ACNM recommend increasing the number of ob-gyns and CNMs/CMs, utilizing inter-professional education to promote collaboration and team-based care.

Recognizing the high level of responsibility that ob-gyns and CNMs/CMs assume when providing care to women, ACOG and ACNM affirm their commitment to promote the highest standards for education, national professional certification, and recertification of their respective members and to support evidence-based practice. Accredited education and professional certification preceding licensure are essential to ensure skilled providers at all levels of care across the United States.

ACOG and ACNM recognize the importance of options and preferences of women in their health care. Ob-gyns and CNMs/CMs work in a variety of settings including private practice, community health facilities, clinics, hospitals, and accredited birth centers.6 ACOG and ACNM hold different positions on home birth.7

Establishing and sustaining viable practices that can provide broad services to women requires that ob-gyns and CNM/CMs have access to affordable professional liability insurance coverage, hospital privileges, equivalent reimbursement from private payers and under government programs, and support services including, but not limited to laboratory, obstetrical imaging, and anesthesia. To provide highest quality and seamless care, ob-gyns and CNMs/CMs should have access to a system of care that fosters collaboration among licensed, independent providers.
