Key points
- A stillbirth is the death of a fetus in utero before or during delivery.
- In most states, stillbirth refers to a loss at or after 20 weeks of pregnancy.
- Talking with families about available resources and testing options can support them during the grieving process.

Why it's important
For many stillbirths, the causes are unknown. A careful evaluation can often provide answers that may help families understand what happened and support the healing process. Every family deserves the opportunity to understand as much as possible about what happened to their baby.
Healthcare professionals can help families by:
- discussing their loss
- helping them access grief and coping resources
- helping them make decisions about testing to try to identify causes
Background
Nearly one-third of stillbirths do not have a known cause.1 Among those with an identified cause, they often fall into three categories:
- the fetus had a birth defect or genetic problem
- the placenta or umbilical cord had a problem
- the mother had certain health conditions (e.g., uncontrolled diabetes)
Conducting a complete and careful evaluation is one of the most important ways to identify a cause for the stillbirth. Even when the cause may seem clear, additional testing may provide useful information.
Different stillbirth evaluation protocols exist. Most include a detailed medical history, an autopsy, evaluation of the placenta, and genetic testing.
Talking about testing
Be sensitive: The parents and other family members are understandably devastated after such a tragic and often unexpected loss. Healthcare providers should be sensitive to these feelings while still explaining the importance of an evaluation. This helps families make informed decisions.
Explain possible next steps: Explaining the evaluation process as part of grief counseling services has proven useful in many institutions. However, each family's decision about evaluation should be respected.
Link families to additional resources: There are alternative options, such as a limited autopsy, that families may prefer. Help families find organizations and resources that may be able to offer them support and guidance.
After the conversation
It is important to fully document patient and clinical information in the medical record. Reporting should include the diagnosis of fetal death, the fetus's weight and other measurements, and an external exam of the fetus. Properly noting and documenting maternal health conditions and relevant lab tests is also critical. Having this information readily available can also help in properly counseling patients regarding future pregnancies.
