Dr. Melinda Threlkeld and Methodist Charlton Medical Center: Texas Medical Board Sanctions Emergency Physician With Just 12 Hours of CME After 22-Year-Old's Death

On March 27, 2026, the Texas Medical Board entered a public Agreed Order against Dr. Melinda Sue Threlkeld, M.D. (Texas Medical License No. R3232), an emergency medicine physician who treated patients at Methodist Charlton Medical Center in Dallas, Texas. The Board concluded that Dr. Threlkeld failed to meet the standard of care, failed to consider alternative diagnoses, failed to escalate care despite clinical evidence of bacterial infection, and failed to keep adequate medical records and that her choices resulted in the death of a 22-year-old patient.

The Texas Medical Board's sanction for Dr. Melinda Threlkeld? Twelve hours of continuing medical education. No license suspension. No probation. No fine. No restriction on her ability to practice emergency medicine. The Order automatically terminates the moment she submits proof she completed the coursework.

This article walks through what the Texas Medical Board found, what happened during the Methodist Charlton Medical Center emergency room visit on October 3, 2023, and why a 12-hour CME requirement is drawing serious questions about how the State of Texas disciplines emergency physicians whose patients die.

Who Is Dr. Melinda Sue Threlkeld, M.D.?

According to the Texas Medical Board's Agreed Order:

• Full name: Melinda Sue Threlkeld, M.D.

• Texas Medical License Number: R3232

• Originally licensed in Texas: May 22, 2017

• Also licensed in: North Carolina and South Carolina

• Specialty: Emergency Medicine

• Board Certification: American Board of Emergency Medicine (a member board of the American Board of Medical Specialties)

Dr. Threlkeld practiced emergency medicine at Methodist Charlton Medical Center, located at 3500 W. Wheatland Road, Dallas, Texas 75237, a facility within the Methodist Health System (MHS) of Dallas.

Until this Order, Dr. Melinda Threlkeld had no prior disciplinary history with the Texas Medical Board.

What Happened at Methodist Charlton Medical Center on October 3, 2023

22-year-old Darren Stanley Jr. at the hospital

On October 3, 2023, a 22-year-old male patient, Darren Stanley Jr., presented to the Methodist Charlton Medical Center Emergency Department with two chief complaints clearly listed in his chart: headache and vomiting. He had been sick for roughly a week. This was his second emergency department visit in five days; he had also been seen at Methodist Charlton on September 28, 2023.

Dr. Melinda Threlkeld was the attending emergency physician. The visit-level diagnoses she documented included:

• Influenza B (primary)

• Mild headache

• Nausea and vomiting

• Elevated procalcitonin

Procalcitonin is a well-known biomarker that rises in response to bacterial infection, not viral illness. An elevated procalcitonin in a young patient with a severe headache, vomiting, and a recent CT scan showing paranasal sinus disease is a recognized red flag for serious bacterial infection, including invasive sinusitis and bacterial meningitis.

A noncontrast CT of the brain performed on September 28, 2023, at Methodist Charlton noted paranasal sinus disease in its impression, directly relevant to the diagnosis Dr. Threlkeld is alleged to have missed.

Despite these findings, Dr. Threlkeld discharged the patient home at 5:42 PM on October 3, 2023. The discharge instructions included a printed handout titled "Home Headache Remedies" advising the patient to dim the lights, drink coconut water, and avoid alcohol. Follow-up was directed to the Methodist Charlton Family Medicine Center within one week.

What the Texas Medical Board Found About Dr. Threlkeld

The Texas Medical Board's findings against Dr. Melinda Threlkeld are quoted directly from the public Agreed Order:

"Respondent failed to meet the standard of care in her treatment of one patient's severe headache, nausea, and vomiting, by not considering alternative diagnoses, like bacterial infection, and not offering other management options."

"Respondent did not offer the patient additional treatment options despite worsening symptoms and lab results indicating a potential infection, including concerning procalcitonin levels and a CT scan showing prior sinus disease, vomiting, and severe headache."

"Respondent chose in this case to wait and monitor the patient despite the patient's evident decline, resulting in the patient's eventual death."

"Respondent also failed to keep adequate medical records regarding the diagnostic process for the patient."

The Board determined that Dr. Threlkeld's conduct violated multiple provisions of the Texas Medical Practice Act and the Board's rules, including:

• Section 164.051(a)(3) and Board Rule 165.1(a) — failure to maintain an adequate medical record

• Board Rule 190.8(1)(A) — failure to treat a patient according to the generally accepted standard of care

• Board Rule 190.8(1)(C) — failure to use proper diligence in professional practice

• Board Rule 190.8(1)(D) — failure to safeguard against potential complications

• Board Rule 190.8(1)(H) — failure to disclose reasonable alternative treatments

• 
  

What Happened After the Methodist Charlton ER Discharge

Less than 24 hours after Dr. Threlkeld discharged the patient from Methodist Charlton, he was rushed to Baylor University Medical Center in Dallas with a fever of 103.6°F, confusion, and altered mental status.

Baylor's findings on October 4, 2023, the day after Dr. Threlkeld sent him home,  were catastrophic:

• CTA Head/Neck: "Invasive sinusitis complicated by left greater than right cavernous sinus thrombosis and left superior ophthalmic vein thrombosis."

• Lumbar puncture: 1,250 white blood cells, 88% neutrophils, glucose of 11, protein of 294 — textbook bacterial meningitis.

• Lactate: 4.7 (sepsis range)

• WBC: 21.1

• CRP: 27

Baylor's emergency surgical team performed an emergency endoscopic sphenoidotomy and ethmoidectomy that same day to drain the infection. Broad-spectrum antibiotics were started. Hyperosmotic therapy was initiated to control brain swelling.

By the morning of October 5, 2023, CT imaging showed "extensive diffuse parenchymal infarction involving the near entirety of the supratentorial parenchyma",  meaning the infection-driven brain swelling and clotting had destroyed most of the brain.

At 1:15 PM on October 5, 2023, the brain death checklist was performed. At 4:11 PM, the 22-year-old patient was pronounced dead.

The cause of death, per Baylor's final ICD-10 diagnoses: bacterial meningitis, sepsis, severe sepsis with septic shock, cavernous sinus thrombosis, intracranial phlebitis, cerebral edema, brain compression, and brain death.

The Baylor ICU progress note documents that "Patient was seen at Methodist Charlton Medical Center 9/28/23 and 10/3/2023 [diagnosed] with sinus headache." The infection was already present and advancing during the Methodist Charlton ER visit when Dr. Threlkeld saw him.

The Texas Medical Board's Sanction Against Dr. Melinda Threlkeld

For an emergency physician whose failure to consider bacterial infection, the Board concluded, "result[ed] in the patient's eventual death," the Texas Medical Board imposed the following:

1. Twelve (12) hours of continuing medical education within one year, broken down as:

   • 4 hours on differential diagnosis in the emergency room

   • 4 hours on medical recordkeeping

   • 4 hours on risk management

2. A requirement to provide a copy of the Order to hospitals where she has privileges.

That is the entire substantive sanction.

The Order specifically preserves Dr. Threlkeld's authority to supervise and delegate prescriptive authority to physician assistants and advanced practice nurses, and to supervise surgical assistants (Paragraph 8).

The Order automatically terminates upon completion of the 12 CME hours and the document distribution requirement (Paragraph 9).

There is no:

• License suspension

• License restriction

• Practice monitoring requirement

• Chart audit requirement

• Required disclosure to patients

• Fine or financial penalty

• Probation in any operationally meaningful sense

Why the 12-CME Sanction for Dr. Threlkeld Is Drawing Scrutiny

The Texas Medical Practice Act gives the Board a wide menu of disciplinary tools under Section 164.001, including license suspension, license revocation, restricted practice, mandatory supervision, mandated practice monitoring, and administrative penalties. The Board chose none of these for Dr. Melinda Threlkeld.

The numbers speak for themselves:

• 12 hours of CME is roughly the same continuing-education load required of a Texas emergency physician every two years simply to maintain licensure.

• The 4 hours on "risk management" is a topic that emergency physicians routinely take voluntarily.

• The 4 hours on "medical recordkeeping" is widely available as a single-afternoon online module.

Patients walking into the Methodist Charlton Medical Center emergency room, or any other emergency room where Dr. Threlkeld practices, have no required notice that this Order exists. The Order is a public record under Texas law and can be looked up on the Texas Medical Board's website by searching License No. R3232 or the name "Melinda Sue Threlkeld."

What Patients Should Know About Methodist Charlton Medical Center and Dr. Melinda Threlkeld

The Texas Medical Board's Order is publicly searchable on the Texas Medical Board physician profile system at tmb.state.tx.us. Anyone considering care at Methodist Charlton Medical Center, or who has been treated by Dr. Melinda Sue Threlkeld, can request a copy of the Agreed Order under the Texas Public Information Act.

Patients who believe they or a family member received substandard emergency care from Dr. Threlkeld or at Methodist Charlton Medical Center should consult a Texas medical malpractice attorney about their rights, including the strict statute of limitations on Texas medical negligence claims (generally two years from the date of the injury under Texas Civil Practice and Remedies Code Chapter 74).

Conclusion: Twelve Hours for a Life

The Texas Medical Board's own findings, in a public Agreed Order, state that an emergency physician at Methodist Charlton Medical Center failed to consider bacterial infection in a 22-year-old patient with elevated procalcitonin, sinus disease on CT, severe headache, and vomiting and that her decision to "wait and monitor" rather than escalate his care resulted in his death.

The Texas Medical Board's response was twelve hours of continuing education.

If twelve hours of CME is the State of Texas's answer when an emergency physician's documented failures result in the death of a young patient, every Texan who walks into an emergency department deserves to ask: what does the Texas Medical Board exist for, and who is it really protecting?
