Hospital nursing standard-of-care expert

Expert class library · Medical malpractice · Either side

A registered nurse, often with clinical and teaching experience in the relevant unit, who testifies whether hospital nurses properly assessed, monitored and documented a patient and escalated changes to a physician. Courts generally let nurses testify to nursing standards and, in many states, to causation where the question is whether a missed sign or a failure to communicate led to harm, but not to the physician's standard of care or to medical diagnoses; trial courts may also limit nursing testimony that duplicates a physician expert.

Questions this testimony turns on

• What did the nursing standard require for assessment and reassessment of this patient, and how often?
• When did the patient's signs change, and were they communicated to a physician as the standard requires?
• Is the expert offering opinions only on nursing care, or also on what a physician should have done?
• Does state law allow a nurse to testify that the nursing breach caused the injury, and is the causal question one of nursing observation or of medical diagnosis?
• Is the nursing testimony needed, or does it repeat what a physician expert has already said?

Methods

• Nursing chart and flowsheet review
• Review of vital sign trends and early warning criteria
• Analysis of escalation and chain of command policies
• Review of hospital policies and protocols
• Timeline reconstruction of assessments and communications

How the testimony is attacked

• Nurse opining on physician care or diagnosis. Defendants argue that a nurse cannot define the physician's standard of care or diagnose. In Bean v. St. Francis Hospital the Oklahoma Supreme Court held that a registered nurse was not qualified to testify to a hospital physician's standard of care and could not establish causation, and affirmed summary judgment for the hospital.
• Causation within nursing expertise. Plaintiffs answer that some causal questions are about recognizing and reporting signs. In Evans v. Medical Center of Central Georgia the Georgia Court of Appeals rejected the argument that a nurse expert was unqualified on causation, because the issue was whether a nurse's failure to identify and communicate symptoms led to a premature discharge, and it reversed summary judgment.
• Cumulative of the physician expert. Defendants seek to strike nursing testimony that repeats a physician's opinions. In Smith v. Clark the West Virginia Supreme Court of Appeals upheld striking a labor and delivery nursing expert after the plaintiff's physician expert testified that the nurses breached the standard of care, under an order limiting each side to one expert per specialty.
• Policies versus standard of care. Defendants argue that a hospital's internal policies do not themselves set the legal standard, and that a deviation from policy is not automatically negligence.
• Charting gaps. Plaintiffs argue that care not documented was not done, while defendants answer with testimony about routine practice and charting by exception.

Most of these rulings come from state courts, which apply their own evidence rules: many follow Daubert, some still apply Frye, and a few exempt certain testimony from a reliability hearing altogether. Check which standard governs in your court before relying on a ruling.

In federal court: amended Rule 702

In federal court, 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.
