Emergency Room Malpractice
in Ohio

How ER malpractice differs from other medical negligence

Emergency room malpractice carries unique legal and medical characteristics that distinguish it from negligence in an outpatient clinic or surgical suite. ER physicians work under extreme time constraints, often seeing dozens of patients per shift, making rapid diagnostic decisions with incomplete information, and managing multiple emergencies simultaneously.

Ohio courts recognize this reality. The standard of care for an ER physician is measured against what a reasonably competent emergency medicine physician would have done under the same or similar circumstances — not what a cardiologist, neurologist, or surgeon with unlimited time would have done. This contextual standard accounts for the chaos and urgency of emergency medicine.

However, the ER environment does not excuse fundamental failures of medical judgment. A reasonably competent ER physician is still expected to take a focused history, perform an appropriate physical examination, order indicated tests, interpret results correctly, consider life-threatening diagnoses in the differential, and either treat or appropriately refer. When these basic obligations are not met — when classic heart attack symptoms are dismissed as anxiety, when stroke symptoms are attributed to a migraine, when a patient with abdominal pain is sent home with undiagnosed appendicitis — the time-pressure defense does not shield the provider from liability.

EMTALA: federal protections for emergency patients

The Emergency Medical Treatment and Labor Act (EMTALA), codified at 42 U.S.C. § 1395dd, is a federal law that imposes specific obligations on hospitals that operate emergency departments and participate in Medicare — which includes virtually every hospital in Ohio.

EMTALA requires two things:

• Medical screening examination (MSE) — the hospital must provide an appropriate medical screening to any individual who comes to the ER requesting examination or treatment, regardless of ability to pay, insurance status, race, national origin, or any other factor
• Stabilization requirement — if the screening reveals an emergency medical condition, the hospital must provide treatment necessary to stabilize the condition before discharge or transfer. A hospital cannot transfer an unstable patient unless the patient requests transfer or a physician certifies that the medical benefits of transfer outweigh the risks

EMTALA violations give rise to a private cause of action — meaning you can sue the hospital directly under federal law. This claim is separate from and in addition to any state medical malpractice claim. EMTALA claims have their own two-year statute of limitations (versus one year for Ohio malpractice), and they do not require expert affidavit of merit under Ohio’s malpractice procedural rules.

Mike evaluates every ER malpractice case for potential EMTALA violations. Common EMTALA scenarios include: refusing to screen uninsured patients, performing a cursory screening that fails to identify the emergency condition, discharging an unstable patient, and transferring a patient to another facility without proper stabilization. Proving an EMTALA violation can significantly strengthen the overall case.

Triage failures: when the first assessment goes wrong

Triage is the gateway to emergency care. When a patient arrives at the ER, a triage nurse performs an initial assessment to determine the urgency of the patient’s condition and assign a priority level. Most emergency departments use the Emergency Severity Index (ESI), a five-level system ranging from ESI-1 (immediate life-threatening) to ESI-5 (non-urgent).

Triage errors are a leading cause of ER malpractice because they delay care during the critical early window when intervention is most effective. The most dangerous triage mistakes include:

• Assigning a low ESI level to a patient presenting with chest pain or shortness of breath, resulting in a prolonged wait while the patient is having a heart attack or pulmonary embolism
• Failing to recognize stroke symptoms — sudden weakness on one side, speech difficulty, facial drooping — as time-critical emergencies requiring immediate CT scan and potential tPA administration within a 3- to 4.5-hour window
• Not taking vital signs at triage, missing tachycardia, hypotension, or fever that would elevate the priority level
• Failing to reassess patients in the waiting room whose condition deteriorates during prolonged waits

Triage is a nursing function, and triage failures typically create liability for both the nurse and the hospital. The triage documentation — timestamp, chief complaint, vital signs, assigned ESI level, and reassessment notes — is critical evidence in these cases. Mike obtains complete triage records and has emergency medicine experts evaluate whether the initial assessment met the standard of care.

Common diagnostic errors in the emergency department

Diagnostic errors are the most frequent basis for ER malpractice claims. The ER environment — high patient volume, limited time per patient, frequent interruptions, and handoff communication failures — creates conditions where critical diagnoses are missed. The most dangerous and common missed diagnoses in Ohio ER malpractice cases include:

Missed heart attack (myocardial infarction)

The standard of care requires an EKG within minutes of arrival for any patient presenting with chest pain, shortness of breath, diaphoresis, or other cardiac symptoms. Serial troponin levels should be drawn to detect cardiac enzyme elevation. Malpractice occurs when the ER physician fails to order these tests, misreads the EKG (missing ST-elevation or depression), attributes the symptoms to musculoskeletal or gastrointestinal causes without adequate cardiac workup, or discharges the patient without serial troponins.

Missed stroke (cerebrovascular accident)

Stroke is the quintessential time-sensitive diagnosis. Ischemic stroke can be treated with tPA (tissue plasminogen activator) if administered within 3 to 4.5 hours of symptom onset. Missing this window — because the ER physician attributed one-sided weakness to a pinched nerve, or failed to order an emergent CT scan, or delayed neurology consultation — can mean the difference between full recovery and permanent disability. The standard of care requires immediate stroke protocol activation when a patient presents with focal neurological deficits.

Missed pulmonary embolism (PE)

Pulmonary embolism is frequently misdiagnosed in the ER because its symptoms — shortness of breath, chest pain, tachycardia — overlap with many less serious conditions. The standard of care requires use of clinical prediction tools (Wells criteria or Geneva score), D-dimer testing for low-probability patients, and CT pulmonary angiography (CTPA) for patients with elevated risk. Failing to consider PE in the differential diagnosis — particularly in patients with risk factors like recent surgery, immobility, oral contraceptive use, or cancer — is a common and often fatal ER error.

Missed appendicitis and other surgical emergencies

Abdominal emergencies — appendicitis, bowel obstruction, ruptured ectopic pregnancy, aortic dissection — require prompt recognition and surgical intervention. Malpractice occurs when the ER physician performs an inadequate abdominal examination, fails to order imaging (CT abdomen/pelvis), attributes pain to a benign cause without adequate workup, or discharges a patient whose condition subsequently deteriorates. In women of childbearing age, failure to perform a pregnancy test before evaluating abdominal pain is a well-recognized standard of care violation.

ER physician liability: employee vs. independent contractor

One of the most legally significant aspects of ER malpractice is determining who is liable — the physician, the hospital, or both. Many ER physicians are not employed by the hospital. Instead, they are employees or independent contractors of emergency medicine staffing companies (such as TeamHealth, Envision Healthcare, or US Acute Care Solutions) that contract with hospitals to provide ER coverage.

Hospitals historically used this arrangement to argue they are not vicariously liable for the ER physician’s negligence, because the physician is not their employee. Ohio law, however, recognizes the doctrine of apparent agency (ostensible agency): if the patient reasonably believed the physician was acting on behalf of the hospital — which is almost always the case in the ER, since patients do not choose their ER doctor — the hospital may be liable regardless of the physician’s technical employment status.

The hospital may also be independently liable under corporate negligence theories — for example, if the ER was chronically understaffed, if nurses were inadequately trained, if equipment was deficient, or if the hospital failed to credential the ER physicians properly. Mike investigates the contractual and employment relationships in every ER case to identify all liable parties and maximize the available recovery.

The time-pressure defense and its limits

Hospitals and ER physicians frequently argue that the time pressure and chaotic environment of the ER should excuse diagnostic errors that would clearly be malpractice in a calmer setting. This argument has some legal validity — Ohio courts do instruct juries to consider the circumstances under which the physician was practicing.

But the defense has clear limits. An ER physician who spends three minutes with a patient complaining of chest pain, orders no EKG or blood work, and discharges the patient with a diagnosis of “heartburn” cannot credibly argue that time pressure prevented a proper workup. An ER that had the patient for six hours before discharge cannot claim the diagnosis was missed due to time constraints.

Mike counters the time-pressure defense by establishing what the physician actually did during the patient encounter — how much time was spent, what tests were ordered, what differential diagnoses were considered — and comparing that to what emergency medicine standards require. The defense erodes quickly when the medical records show the physician simply didn’t do the work.

Statute of limitations for ER malpractice in Ohio

ER malpractice claims are subject to Ohio’s general medical malpractice statute of limitations: one year from the date of the negligent act or the date the injury was discovered or should have been discovered, under R.C. § 2305.113. There is also a four-year statute of repose — no claim can be filed more than four years after the act of malpractice, regardless of when the injury was discovered.

For EMTALA claims, the statute of limitations is two years under federal law, starting from the date of the EMTALA violation. This longer window can be strategically important when the state malpractice deadline has passed but the EMTALA claim remains viable.

Because ER visits are discrete events with clear dates, the statute of limitations often runs from the actual ER visit date — making the deadline predictable but also unforgiving. Mike urges anyone who suspects negligent ER care to consult an attorney promptly. The one-year deadline leaves limited time for expert review, record collection, and case investigation before suit must be filed.
