Mercy Health - Women's Health Physicians and Midwives has been recognized as a “Best Practice” by the American College of Nurse-Midwives for achieving the “Triple Aim” target by the institute of Medicine.


“Triple Aim” is comprised of:

  1. Improving patient experience
  2. Improving the health of populations
  3. Reducing the cost of care

In order to achieve this designation, Mercy Health - Women's Health Physicians and Midwives had to meet or exceed having a primary cesarean rate less than 23.9 percent, preterm birth rate less than 11 .4 percent and exclusive breastfeeding greater than 81 percent.


In 2015, our rates were 12.3 percent for primary cesarean, were less than 11.4 percent for preterm birthrates, and 94 percent breastfeeding rate.


This recognition is the result of a team-based approach to healthcare between the nurse midwives, their collaborating physician, Dr. Tess Gordon, and Maternal-Fetal Medicine specialist, Dr. Ramu Perni. While the midwives have always provided care to low-risk women, the team-based approach has allowed high-risk pregnancies to stay in their care and benefit from the personal touch that is the hallmark of midwifery.


The Triple Aim best practice recognition was achieved by less than 80 midwifery practices nationwide.
