Common medical mistakes during pregnancy and childbirth include failing to diagnose a health condition or failing to treat a condition appropriately once it has been diagnosed. A doctor also may fail to regularly monitor a mother and a child for certain known risks, or they may fail to carefully review the medical history of a mother. After a patient undergoes a procedure, a doctor may fail to follow up to resolve any complications that arise. Even if a doctor eventually corrects their mistake, serious harm may result from a delay that should not have occurred.
