If you or a loved one suffered harm after visiting an ER in Kansas City or elsewhere in Missouri, you may have the right to file a claim. Below, we’ll explain what qualifies as emergency room negligence, how to recognize the signs, and what steps to take if you suspect malpractice.

What Is Emergency Room Malpractice in Missouri?

Emergency room malpractice occurs when an ER doctor, nurse, or hospital staff member fails to meet the appropriate professional standard of care, resulting in patient injury or death. In Missouri, these cases fall under medical malpractice law and require proof that the provider’s actions or inaction directly caused a patient harm. This standard can be challenging to meet, especially in high-stress ER settings. However, emergency room personnel are still held accountable for:
  • Failing to recognize or treat life-threatening symptoms,
  • Misdiagnosing serious medical conditions,
  • Administering the wrong medication or dosage,
  • Ignoring or misreading diagnostic tests, and
  • Discharging patients too early without adequate testing.
In any case, the key question is whether the provider acted as a reasonably competent professional would under similar circumstances.

Common Forms of ER Negligence in Missouri

While emergency rooms are designed to triage and treat quickly, mistakes often happen when corners are cut or protocols aren’t followed. Here are the most common grounds for an ER negligence lawsuit in Missouri.

1. Emergency Room Misdiagnosis in Kansas City

ER physicians may incorrectly diagnose or completely miss serious conditions such as:
  • Heart attacks (especially in women),
  • Strokes,
  • Brain hemorrhages,
  • Sepsis or infections,
  • Internal bleeding, and
  • Appendicitis. 
Misdiagnosis can delay treatment and lead to irreversible harm, or even death.

2. ER Delay in Treatment Legal Claim

Long wait times, overwhelmed staff, or a failure to prioritize symptoms can result in deadly delays. A patient suffering from a stroke or cardiac event may be forced to wait hours for treatment, with catastrophic consequences.

3. Medication Errors

Emergency rooms are fast-paced and chaotic, but that doesn’t excuse giving the wrong medication or dosage. Administering drugs to which a patient is allergic or mixing incompatible medications can cause permanent damage.

4. Failure to Order Necessary Tests

If your condition worsened because an ER doctor skipped crucial imaging (such as a CT scan) or bloodwork, that may be grounds for malpractice.

5. Discharging a Patient Too Soon

Some patients are sent home while still experiencing dangerous symptoms. If an early discharge results in a medical emergency, the ER staff may be held liable.

How to Prove Emergency Room Malpractice in Missouri

To succeed in a malpractice case, you must show:
  • A doctor-patient relationship existed—such as you being formally treated by the medical provider or ER staff;
  • The provider failed to meet the standard of care—meaning they acted negligently or omitted necessary steps;
  • Their negligence caused your injury—allowing you to establish a clear link between the mistake and the harm you suffered; and
  • You suffered damages—such as physical harm, emotional distress, medical bills, lost wages, etc.
These cases require thorough investigation and testimony from medical experts who can explain what should have been done differently. At Dempsey Kingsland & Osteen, we have in-house medical professionals who help build compelling claims for our clients.

Signs You May Be a Victim of ER Negligence

Not every poor outcome is grounds for a lawsuit, but here are red flags that may indicate emergency room malpractice in Missouri:
  • You were diagnosed with a serious condition shortly after being discharged from the ER;
  • Your symptoms were ignored or dismissed as minor despite obvious distress;
  • You were given medication that caused a severe or allergic reaction;
  • Your loved one died after being sent home from the ER without proper evaluation; and
  • The ER failed to run tests that later revealed a life-threatening condition.
If any of these situations apply, it’s worth having an attorney review your case.

How Long Do You Have to File an ER Malpractice Claim in Missouri?

In Missouri, most ER negligence lawsuits must be filed within two years of the date of injury or discovery of the injury. However, there are exceptions, especially in cases involving minors or wrongful death. Time is critical. Evidence must be preserved, and medical records must be reviewed. If you wait too long, you may lose the right to recover compensation.

What Compensation Can You Recover in an ER Negligence Lawsuit?

If your case is successful, you may be entitled to damages for:
  • Past and future medical bills,
  • Lost income or earning capacity,
  • Pain and suffering,
  • Disability or disfigurement,
  • Emotional trauma, and
  • Loss of companionship (in wrongful death cases).
Each case is different, and compensation will vary depending on the severity of your injuries and the long-term impact on your life.
