In a complex medical malpractice case, finding a highly credentialed doctor is not necessarily enough.
Kansas law asks another question.
Was that doctor actually spending enough time treating patients?
That distinction can become critical in litigation involving a child’s brain injury, where expert testimony may be needed to explain fetal monitoring, neonatal care, oxygen deprivation, imaging, neurological injury, and whether different medical care would probably have changed the outcome.
An expert may have an impressive résumé and decades of experience. Yet when the expert is offered to testify about the applicable medical standard of care, Kansas imposes a specific clinical-practice requirement that can determine whether the testimony is admitted at all.
Kansas Looks at What the Expert Was Actually Doing
K.S.A. 60-3412 governs expert qualifications in Kansas medical malpractice actions when the standard of care provided by a practitioner of the healing arts is at issue.
The statute requires the proposed expert to have devoted at least 50% of their professional time, during the two years before the incident, to actual clinical practice in the same profession in which the defendant is licensed.
That can make expert selection an early strategic issue for a child brain injury lawyer Wichita case involving alleged medical negligence.
A physician who spends nearly all of their time consulting for lawyers, teaching, publishing, or performing administrative work may possess substantial medical knowledge but still face a qualification challenge under the statute.
Kansas courts have described the rule as a way of limiting reliance on professional expert witnesses whose work has become disconnected from current clinical practice.
“Same Profession” Does Not Mean “Same Specialty”
The statute can sound stricter than Kansas courts have actually interpreted it.
A common assumption is that an obstetrician may testify only against another obstetrician, a neurologist only against another neurologist, or a surgeon only against the same type of surgeon.
Kansas Supreme Court precedent does not establish such a rigid same-specialty rule.
In Glassman v. Costello, the court explained that the statute was intended to require substantial clinical practice, not to restrict standard-of-care testimony exclusively to physicians working in an identical specialty.
That distinction matters in complicated medical cases.
The proper expert may sometimes come from a different specialty but still possess the training and clinical experience necessary to address the particular standard-of-care question before the court.
Whether that testimony is persuasive remains a separate issue for the litigation.
Qualification gets the expert through the door. It does not guarantee that a judge or jury will accept the opinion.
Even a Treating Doctor Does Not Automatically Qualify
Kansas has also rejected another potentially tempting shortcut.
A physician who actually treated the patient is not automatically exempt from the 50% requirement when being offered as an expert on the standard of care.
In Schlaikjer v. Kaplan, the Kansas Supreme Court held that K.S.A. 60-3412 applies to any witness giving expert standard-of-care testimony in a medical malpractice action, including a treating physician.
The label attached to the witness therefore matters less than the testimony the witness is being asked to provide.
A treating doctor can testify about observations and treatment within the ordinary rules of evidence. But once that physician is being used as an expert to establish the professional standard governing another provider’s care, the statutory qualification issue can arise.
That is one reason the role of expert witnesses needs to be defined carefully before trial rather than treated as a question of credentials alone.
Child Brain Injury Cases Rarely Involve One Medical Question
The expert problem becomes even more interesting in birth-related brain injury litigation because the case may cross several areas of medicine.
One specialist might address management of labor. Another may interpret fetal heart-rate patterns. A neonatologist may evaluate the baby’s condition immediately after delivery. A pediatric neurologist may discuss the nature and timing of neurological injury.
Those opinions do not necessarily answer the same legal question.
One expert may be addressing standard of care: what a reasonably competent provider should have done.
Another may focus on causation: whether the alleged error probably contributed to the brain injury.
A separate expert may address future medical needs or functional limitations.
Kansas’s 50% clinical-practice statute specifically addresses qualification to testify on the standard of care in a medical malpractice action. Other expert issues are also governed by Kansas evidence law and the requirements applicable to the particular opinion being offered.
The practical lesson is that “we have a medical expert” may be much too vague for complex litigation.
The important question is which expert is proving which part of the case.
Expert Testimony Is Usually Needed When Medicine Is Beyond Ordinary Knowledge
Kansas courts recognize a limited common-knowledge exception to the usual need for expert medical testimony.
If the alleged lack of reasonable care is so obvious that an ordinary juror can understand it without specialized medical knowledge, expert testimony may not be necessary on that issue.
A classic example would be leaving a foreign object inside a patient after surgery.
But complicated questions about fetal monitoring, neonatal neurological injury, oxygen deprivation, timing of brain damage, or the appropriate response to changing clinical signs are generally very different.
In Schlaikjer, the Kansas Supreme Court reiterated that expert testimony is ordinarily required when the medical issue falls outside the everyday knowledge of jurors.
That makes expert evidence more than supporting material in many serious malpractice cases. Without admissible testimony establishing a required element, the case can fail before a jury ever reaches the underlying factual dispute.
A Bad Outcome and Medical Negligence Are Still Different Things
Expert testimony also prevents another mistake: treating the severity of an injury as proof that malpractice occurred.
A child can suffer a devastating medical outcome without any provider violating the standard of care.
Conversely, a treatment error may occur without causing the neurological condition later diagnosed.
A malpractice case has to separate those questions.
A discussion of medical negligence therefore begins with more than the presence of serious harm. The evidence must address what care was required, what actually occurred, and whether any departure from appropriate care caused the injury being claimed.
In a child brain injury case, those conclusions often depend on doctors who can translate highly technical medical evidence into legally relevant opinions.
Kansas adds another layer by asking whether the person offering the standard-of-care opinion was sufficiently engaged in real clinical medicine when the incident occurred.
The Expert’s CV Is Only the Starting Point
Medical malpractice litigation naturally places emphasis on credentials.
Board certification, research, academic appointments, publications, and professional reputation can all matter.
Kansas law adds a more practical question.
How much medicine was the expert actually practicing?
For standard-of-care testimony, that answer can determine whether an otherwise impressive opinion is available to the court at all.
In a case involving a child’s neurological injury, where medical evidence may already be unusually complicated, discovering an expert qualification problem late in the litigation can affect far more than one witness.
It can affect the evidence available to prove the claim itself.
