Emergency Room Errors
Emergency rooms are high-pressure environments where split-second decisions can mean the difference between life and death. When ER staff make preventable mistakes — from triage failures to premature discharges — the consequences for patients can be devastating.
What Are Emergency Room Errors?
Emergency room errors are preventable mistakes made by physicians, nurses, and other staff in the emergency department that result in harm to patients. The emergency room presents unique challenges: patients arrive with undifferentiated complaints, physicians must make rapid decisions with incomplete information, and the environment is often chaotic with high patient volumes and competing demands on attention and resources.
While these challenges are real, they do not excuse negligent care. ER physicians are trained to function in high-acuity, time-pressured settings and are held to the standard of a reasonably competent emergency medicine physician under similar circumstances. The most common ER errors involve diagnostic failures — sending patients home with undiagnosed heart attacks, strokes, pulmonary embolisms, or other life-threatening conditions that a careful evaluation would have caught.
Triage is the critical first step in emergency care, where patients are assessed and prioritized based on the severity of their condition. Triage errors — such as assigning a low priority to a patient who is actually having a cardiac event or classifying an ectopic pregnancy as routine abdominal pain — can result in dangerous delays in treatment. The Emergency Severity Index (ESI) is the most widely used triage system, and failures to properly apply it are a common source of ER malpractice claims.
Premature discharge is another major category of ER error. Patients may be sent home before their condition has been adequately evaluated or stabilized, often due to pressure to maintain patient throughput. The federal EMTALA law requires hospitals to provide a medical screening examination and stabilize emergency conditions before discharge, and violations of this law can carry severe penalties. Patients who are discharged prematurely and subsequently deteriorate may have claims for both state malpractice and federal EMTALA violations.
Systemic factors contribute significantly to ER errors. Chronic overcrowding, nurse-to-patient ratios that exceed safe levels, inadequate handoff communication during shift changes, and the growing practice of staffing ERs with physicians who lack board certification in emergency medicine all increase the risk of patient harm. When a hospital fails to address these systemic issues, it may bear independent liability for the errors that result.
Common Examples of ER Errors
Triage Failures
Incorrectly assessing a patient's condition severity, resulting in a critically ill patient waiting hours for evaluation while less acute patients are seen first.
Premature Discharge
Sending patients home before their condition has been properly diagnosed or stabilized, often to free up beds during overcrowding.
Missed Heart Attacks
Failing to order an ECG or cardiac enzymes for patients presenting with chest pain, shortness of breath, or atypical cardiac symptoms, particularly in women and younger patients.
Missed Strokes
Failing to recognize stroke symptoms or to order emergent CT/MRI imaging, resulting in missed treatment windows for thrombolytic therapy or thrombectomy.
Overlooked Fractures
Missing fractures on X-rays, particularly subtle fractures of the scaphoid, C-spine, ribs, or stress fractures that can worsen without proper immobilization.
Failure to Order Appropriate Tests
Not ordering imaging, blood work, or other diagnostics warranted by the patient's presentation — for example, not performing a CT angiogram to rule out pulmonary embolism.
Overcrowding and Understaffing Errors
Mistakes that result from dangerously high patient-to-staff ratios, including delayed treatment, inadequate monitoring, and failure to reassess patients who are waiting.
Handoff Communication Failures
Critical patient information lost during shift changes or transfers between departments, leading to gaps in care or treatment of the wrong condition.
Key Questions an Attorney Would Investigate
Was the patient properly triaged using an established severity index upon arrival?
Were appropriate diagnostic tests ordered based on the patient's presenting complaints?
Was the patient's condition adequately stabilized before discharge per EMTALA requirements?
Were proper discharge instructions given, including warning signs to watch for?
Did overcrowding or understaffing contribute to the patient not receiving timely care?
Was there a communication failure during shift changes that led to the error?
Were all test results reviewed before the patient was discharged?
Was the ER physician board-certified in emergency medicine or appropriately supervised?
