Necrotizing fasciitis is an aggressive, rapidly spreading bacterial infection that destroys skin, fat, and the connective tissue surrounding muscle. More than half of all patients who present with this condition receive the wrong diagnosis on their first visit to a healthcare provider, which makes necrotizing fasciitis misdiagnosis one of the most devastating diagnostic failures in modern medicine. Doctors frequently mistake the early signs of this infection for a routine skin infection. The consequences of a delayed diagnosis range from extensive surgical debridement, amputation, organ failure, and death.
Dempsey Kingsland & Osteen represent Kansas City clients and their families who suffered a delay in recognizing necrotizing fasciitis that turned a survivable infection into a catastrophic injury or death. Our attorneys bring over 40 years of experience in complex medical malpractice litigation in both Kansas and Missouri, working with our in-house physicians and nurses to compare the patient’s symptoms and lab values with what a reasonably careful provider should have recognized at the time.
If you believe a doctor or hospital missed the warning signs of necrotizing fasciitis in you or someone you loved, contact Dempsey Kingsland & Osteen to find out whether that delay amounts to malpractice.
Key Takeaways
Necrotizing Fasciitis Misdiagnosis: What Missouri and Kansas Patients Should Know
A necrotizing fasciitis misdiagnosis can turn a survivable infection into amputation, organ failure, or death. These are the points our Kansas City team looks at first when a fast-moving infection was missed.
- Early signs often look like cellulitis. Redness, swelling, and pain near a wound can mimic a routine skin infection, but pain that feels out of proportion to how the skin looks is a key warning sign.
- Every hour of delay matters. The infection spreads along the fascia faster than it shows on the skin, moving toward sepsis, organ failure, and tissue death severe enough to require amputation.
- Missouri recognizes loss of chance. Recovery may be possible when a missed diagnosis measurably reduced a patient’s chance of survival, even if that chance was already below 50%. A health care affidavit must be filed within 90 days of filing suit.
- Expert testimony and deadlines apply in both states. Missouri generally allows two years from the date of injury, and Kansas generally allows two years from injury or discovery, with a four-year statute of repose.
Why Is Necrotizing Fasciitis Often Missed?
In its early hours, necrotizing fasciitis looks almost identical to cellulitis, a far more common and far less dangerous skin infection. Both start with redness, swelling, and pain at the site of a cut, scrape, or surgical wound. The dramatic signs most clinicians associate with necrotizing fasciitis develop late in the disease course, and include:
- Purple skin discoloration,
- Hemorrhagic bullae,
- Crepitus, and
- Visible necrosis.
The clue that should raise an alarm but often gets overlooked is pain that feels disproportionate to how mild the skin looks.
Understanding the Role of Pain
Postsurgical patients have their escalating pain dismissed as normal recovery discomfort. Patients with diabetic neuropathy may feel no pain at all. Because necrotizing fasciitis is genuinely rare, many physicians will encounter only one or two cases in their careers, making a flesh-eating bacteria misdiagnosis a persistent problem even among experienced clinicians. However, a disease being rare does not make it acceptable to miss.
What Is the Impact of a Delayed Necrotizing Fasciitis Diagnosis?
A delayed necrotizing fasciitis diagnosis carries consequences that escalate by the hour. The infection spreads along the fascia faster than it spreads across the visible skin, so surgeons often find far more damage during surgery than the external appearance suggests. Every hour that passes allows the infection to progress toward sepsis, organ failure, and tissue death severe enough to require amputation.
How Do You Establish Liability in Missouri?
Missouri requires a plaintiff to establish the following four elements to prevail in a nec fase malpractice action:
- Duty of care. The plaintiff must prove that a physician-patient relationship existed, establishing a duty of care.
- Breach. The plaintiff must demonstrate that the physician breached the applicable standard of care by missing warning signs such as pain out of proportion or rapid progression despite antibiotics, and whether the physician took appropriate action,
- Causation. Next, the plaintiff must prove that the breach directly caused the patient’s injuries through a “but for” causation standard that shows earlier recognition would have changed the outcome.
- Damages. Lastly, the plaintiff must demonstrate actual damages resulting from the physician’s negligence.
Because necrotizing fasciitis carries a mortality rate of roughly one in four to one in three, even with prompt treatment, a patient’s odds of survival may already have been below 50% at the time a diagnosis was missed. Missouri recognizes a narrow loss-of-chance doctrine for exactly this situation, allowing recovery when a physician’s negligence measurably diminished a patient’s chance of survival, even if that chance was already less than even before the delay.
Missouri also imposes a strict procedural requirement before a case can even proceed. A plaintiff must file a health care affidavit within 90 days of filing suit, confirming that a qualified provider has reviewed the case and believes the defendant’s conduct fell below the standard of care and caused the patient’s injury.
What Is Needed to Establish Liability in Kansas?
Kansas requires the same underlying four elements, but analyzes causation through its own framework, actual causation, meaning the delay genuinely caused the harm, and proximate causation, meaning the harm was a foreseeable result of that delay rather than something unrelated. Kansas courts apply this analysis to necrotizing fasciitis cases the same way they apply it to any other diagnostic delay, asking what a reasonably careful physician would have recognized and done differently.
Are There Any Common Requirements in Both States?
In both states, expert testimony is not optional. Whether a physician should have suspected a rare, fast-moving infection is a medical judgment call outside common knowledge. No jury can resolve that question without a qualified expert explaining what the standard of care required is and how a faster diagnosis would have changed the outcome. Kansas courts are known to strictly enforce the use of expert testimony.
Racing the Clock: What Are the Filing Deadlines in Missouri and Kansas?
Under Missouri law, the statute of limitations for medical malpractice is typically two years from the date the injury occurred. However, in some instances, you may sometimes have more than two years. Kansas imposes a similar two-year deadline, generally running from the date of injury or its discovery. Kansas also imposes a four-year statute of repose after the negligent act, regardless of when the injury was actually discovered. This shorter repose period in Kansas makes prompt legal consultation especially critical.
Recognizing What Was Missed
A necrotizing fasciitis misdiagnosis destroys lives in ways few other medical errors can match. When a physician fails to recognize the warning signs of this rapidly progressive infection, patients pay the price in lost limbs, lost function, and lost lives. Missouri and Kansas both provide a path to accountability for patients who suffer such catastrophic harm, but these cases demand the medical skill most law firms lack in-house.
Dempsey Kingsland & Osteen work alongside physicians and nurses for exactly this reason, so a treating physician’s chart notes are reviewed by clinicians qualified to identify what those findings should have prompted at the time. We pursue every case of treating a missed diagnosis of a fast-moving infection with the same seriousness as any other catastrophic failure of care.
If you or someone you love suffered a serious injury or loss because a flesh-eating infection went unrecognized in Missouri or Kansas, contact Dempsey Kingsland & Osteen to discuss whether that delay amounts to a malpractice claim.
