Obstetrics standard-of-care expert
Expert class library · Medical malpractice · Either side
An obstetrician who reviews prenatal care and labor management, decisions about cesarean timing, use of Pitocin and vacuum or forceps, handling of shoulder dystocia and response to fetal distress in birth injury cases. Courts usually admit opinions built on the expert's clinical experience applied to the chart, and police the line between a standard-of-care opinion and a causation opinion the expert cannot support.

What this expert is retained to answer
- What would a reasonable obstetric provider have done at each point in the prenatal course, labor and delivery, and where did the care depart from it?
- Is the opinion that the provider breached the standard of care based on the records and the delivery itself, or only on the fact that the child was injured?
- How does the expert's clinical experience support the opinion, and how does the expert answer ACOG publications or studies the other side relies on?
- Does the expert actually practice in the area at issue, and does the standard he applies match the defendant's specialty and the time of the care?
- Is the expert also offering a causation opinion, and if so, what literature supports it?
Methods
- Labor curve and partogram review
- Pitocin dosing review
- Decision-to-incision interval analysis
- Shoulder dystocia maneuver and traction review
- ACOG guideline comparison
How the testimony is attacked
- Experience is not a method. Defendants argue that an opinion resting on the expert's own practice is not the product of reliable principles. In Seifert v. Balink the Wisconsin Supreme Court rejected that argument and held that an obstetrician's experience-based opinion on the standard of care in a shoulder dystocia delivery was reliable under the state's Daubert rule.
- Res ipsa dressed as expert opinion. Defendants argue that the expert infers a breach from the mere fact of a permanent injury. In Wong v. Broughton the Delaware Supreme Court upheld admission of the plaintiff's obstetrician's excessive traction opinion because it rested on the records, eyewitness accounts, the ruling out of other causes and decades of practice, not on the injury alone.
- Contrary ACOG literature. Opponents cite an ACOG monograph or committee opinion that points to another explanation, such as maternal forces in brachial plexus injuries. In Wong the courts treated the expert's reasons for disagreeing with the monograph as a matter for cross-examination and the jury.
- Causation opinions with no literature behind them. Obstetricians offered on standard of care sometimes add causation or timing opinions. In Richardson v. Christiana Care the Superior Court barred the defense obstetricians' opinion on when an infant was infected with HIV because no literature supported it and contrary literature existed, while letting one of them testify on the standard of care.
- Out of date or wrong specialty. Challengers argue the expert no longer delivers babies or practices a different specialty from the defendant. In Richardson the court treated a maternal fetal medicine physician's years away from routine obstetric care as a matter of weight, given his board certification and work on the governing ACOG guidance.
What the public record shows
A deliberately narrow CourtListener search, "standard of care" AND obstetric* AND (labor OR delivery OR cesarean) AND (Daubert OR "Rule 702"), returned 38 opinions filed since 2015, as of October 3, 2026; broader searches return more. Three that show how courts handle this class of testimony:
| Outcome | Case | Court | Why |
|---|---|---|---|
| Admitted | Seifert v. Balink2017 WI 2, 372 Wis. 2d 525, 888 N.W.2d 816 | Wis. 2017 | The Wisconsin Supreme Court held under the state's Daubert-based Rule 702 analogue that the plaintiff's obstetrician could give an experience-based opinion that a family doctor practicing obstetrics breached the standard of care in prenatal care and a shoulder dystocia delivery, so the trial court properly admitted it. |
| Admitted | Wong v. Broughton204 A.3d 105 | Del. 2019 | The Delaware Supreme Court affirmed admission under D.R.E. 702 and Daubert of the plaintiff's obstetrician's opinion that excessive lateral traction during a shoulder dystocia delivery breached the standard of care, holding it was grounded in the records, eyewitness accounts and his experience rather than an inference from the injury alone. |
| Limited | Richardson v. Christiana Care Health Services, Inc.C.A. No. N18C-10-026 JRJ | Del. Super. Ct. 2021 | In a perinatal HIV transmission case the Superior Court excluded the defense obstetricians' causation opinion on the timing of infection as unreliable for lack of supporting literature, but allowed one of them to testify on the standard of care for prenatal HIV testing despite his move into maternal fetal medicine. |

Under amended Rule 702
Since December 1, 2023, Rule 702 says expressly that the party offering an expert must show the court it is more likely than not that the testimony meets each requirement: that it rests on sufficient facts or data, uses reliable methods, and reflects a reliable application of those methods to the case. Questions about the basis of an opinion are no longer automatically matters of weight for the jury. For how the circuits have applied the amendment, see the Rule 702 tracker, which follows each court of appeals; for what that means for preparing or attacking this class of expert, see the guide on amended Rule 702.

Last reviewed October 3, 2026. How this page is built: rulings are found by searching court opinions on CourtListener, and each one is read in the opinion before it is summarised here; outcomes are labelled by what the court did with the expert's testimony. No individual expert is named. This page summarises public decisions for orientation and is not legal advice; read the opinion before relying on any ruling.
