Short answer: Emergency room negligence happens when ER doctors, nurses, or the hospital fall below accepted emergency care standards, for example through dangerous triage delays, an unsafe discharge, or a treatment error, and that causes real harm. In New York, most claims must start within two and a half years, public hospitals require a notice of claim within 90 days, and New Jersey, Pennsylvania, and Connecticut set their own deadlines.
This is general information, not legal or medical advice. Laws change and every case is different, so speak with your doctor and a lawyer licensed in your state about your situation.
What counts as emergency room negligence?
ER staff work under pressure, so they are judged against what a reasonably careful emergency team would have done in the same situation, not against perfect hindsight.
A claim generally needs evidence that a provider acted, or failed to act, in a way a careful ER team would not have, and that this caused harm such as a worsening infection, brain injury, or death. If proper care would not have changed the outcome, there is usually no claim.
What are common ER errors?
- Triage delays: a patient with warning signs, such as chest pain, stroke symptoms, or signs of infection, is given low priority and waits too long.
- Unsafe discharge: sending someone home with abnormal vital signs, without needed tests, or without clear follow-up instructions.
- Test results not acted on: lab work or imaging comes back abnormal after the patient has left, and no one calls.
- Medication errors: wrong drug or dose, or ignoring a known allergy.
- Handoff and communication gaps: key information lost at shift change or between the ER and specialists.
- Delayed specialist care: a needed surgeon is not called, or treatment is postponed while the patient worsens. For one example of how delay can play out inside a hospital, see KDLM’s account of a delayed gallbladder surgery case.
What does federal law require of emergency rooms?
The Emergency Medical Treatment and Labor Act (EMTALA) applies to Medicare-participating hospitals that offer emergency services. As the Centers for Medicare & Medicaid Services explains on its EMTALA overview, these hospitals must give anyone who asks a medical screening exam, provide stabilizing treatment for an emergency condition, including active labor, or arrange an appropriate transfer, regardless of ability to pay.
EMTALA is not a general malpractice law. It mainly covers refusing to screen, failing to stabilize, and improper transfers. A civil claim under it is brought against the hospital and must generally be filed within two years of the violation.
What should you do after a suspected ER error?
- Get medical care. If symptoms continue or worsen, go back or seek care elsewhere right away.
- Write it down. Note arrival and discharge times, names, and what you were told.
- Request your records. Ask for the full ER chart, including triage notes, nursing notes, vital signs, orders, lab and imaging results, and discharge papers. Our guide on getting your medical records in New York explains your rights and fees.
- Check who runs the hospital. Many NYC emergency rooms belong to NYC Health + Hospitals, which means a much shorter deadline.
What are the deadlines in New York, New Jersey, Pennsylvania, and Connecticut?
Rules differ by state. These summaries cover claims against private hospitals and doctors; public hospitals can follow different rules.
New York
- Filing deadline: under CPLR 214-a, generally 2 years and 6 months from the error or from the end of continuous treatment for the same condition.
- Discovery rule: limited. A foreign object left in the body allows 1 year from discovery, and certain missed cancer cases have a discovery-based rule. Most ER claims run from the visit date.
- Certificate of merit: CPLR 3012-a generally requires the lawyer to certify that a physician reviewed the case and found a reasonable basis for it.
- Wrongful death: generally 2 years from death under EPTL 5-4.1. The Grieving Families Act, which would expand this law, was vetoed in December 2025, and the 2026 version did not pass.
- Public hospitals: a notice of claim is generally due within 90 days. See our guide to the notice of claim for NYC public hospitals.
New Jersey
- Filing deadline: generally 2 years under N.J.S.A. 2A:14-2.
- Discovery rule: yes. Courts may delay the clock until you knew, or reasonably should have known, of the injury and that someone may be at fault.
- Affidavit of merit: under N.J.S.A. 2A:53A-27, due within 60 days after the defendant’s answer, with one possible 60-day extension.
- Wrongful death: generally 2 years from death under N.J.S.A. 2A:31-3.
Pennsylvania
- Filing deadline: generally 2 years under 42 Pa.C.S. § 5524.
- Discovery rule: yes. The clock can start when you knew, or reasonably should have known, of the injury and its cause. The seven-year repose limit for adult claims was struck down in 2019.
- Certificate of merit: under Pa.R.C.P. 1042.3, filed with the complaint or within 60 days after it.
- Wrongful death: generally 2 years from death in medical cases, unless the cause of death was concealed.
Connecticut
- Filing deadline: under C.G.S. § 52-584, 2 years from when the injury was sustained or discovered, but no more than 3 years from the error.
- Discovery rule: built in, capped by the 3-year limit. An automatic 90-day extension is available by petition for a pre-suit review.
- Certificate of good faith: under C.G.S. § 52-190a, filed with the complaint along with a written opinion from a similar health care provider.
- Wrongful death: under C.G.S. § 52-555, generally 2 years from death and no more than 5 years from the error.
Children’s claims and continuous treatment can change these dates; treat them as starting points.
How do ER negligence cases usually work?
A lawyer collects the records and has an emergency medicine expert review the timeline: arrival, triage, tests ordered, and when results came back. Time-stamped ER records are often the central evidence. Some ER doctors are outside contractors rather than hospital employees, which affects who is responsible. Our guide on how long a malpractice lawsuit takes in New York explains the stages that follow.
How do you find a lawyer for an ER claim?
Look for a firm that handles malpractice regularly, works with emergency medicine experts, and is licensed where the hospital is. You can compare firms in the Top Lawyers category and on the New York location page, including the Kramer, Dillof, Livingston & Moore profile. Ask about experience and fees. No lawyer can guarantee a result.
Outcome: protect your health and your options
Get care first, write down the timeline, and request the complete ER chart. Check whether the hospital is public, which can mean a 90-day notice deadline, and note your state’s filing deadline. Then a qualified lawyer can tell you whether what happened was an unavoidable outcome or emergency care that fell short.
FAQs
Can you sue an emergency room for negligence in New York?
Yes, if ER care fell below accepted practice and caused harm. Private-hospital claims usually must start within two and a half years; public hospitals need a notice of claim within 90 days.
Is a long wait in the ER negligence?
Not by itself. A wait can be negligent if triage missed clear warning signs and the delay caused harm that timely care would likely have prevented.
What is EMTALA?
A federal law requiring most hospitals with emergency departments to screen and stabilize anyone with an emergency condition, or arrange an appropriate transfer, regardless of ability to pay.
What if an ER error caused a death?
The estate may bring a wrongful death claim. In all four states the deadline is generally two years from death, with extra limits in some.
