Healthcare Partnership for Expecting Moms and Newborns

KHC strives to ensure that all of its patients receive exceptional healthcare. When it comes to patient care, we understand that many medical services can be delivered locally, either by one of KHC’s providers or a visiting specialist. However, we also understand that some services are best provided by a major hospital system or specialty center prominent in their field of medicine.

Most pregnancies occur without complications. However, some women who are pregnant will experience complications that can involve their health, their baby’s health, or both. Sometimes, diseases or conditions the mother had before she became pregnant can lead to complications during pregnancy. Some complications occur during delivery.

That’s why we feel it is so important that women and their newborns have access to a prominent birthing center and neonatal center, should it be needed. It is also the reason why KHC formed a partnership with Mercy of Des Moines. Mercy is the premier hospital in the region for childbearing, perinatal, and neonatal care. Whether your birth experience is simple or complicated, their obstetricians and birth center medical staff will provide you and your baby the best care possible.

Through this partnership, patients receive most of their prenatal care locally from one of KHC’s medical providers. Then, during a patient’s last few weeks of pregnancy, their care is transitioned to Mercy of Des Moines for the remainder of their term and through delivery. Following childbirth and recovery, new moms return to KHC to receive their postpartum and well-baby care close to home.

While at Mercy, patients have access to exceptional services for women and infants, such as:

  • Free childbirth classes
  • Luxurious birthing suites
  • Dedicated Cesarean section rooms with private recovery areas
  • Lactation consultants
  • Perinatal Center of Iowa
  • OB Emergency and Antepartum Unit
  • Neonatologists, maternity triage and treatment unit for women experiencing complications or early labor
  • Variety Neonatal Intensive Care Unit to care for the most vulnerable patients
