Discovering that a sponge, surgical instrument, needle, or other object was left inside your body after an operation raises an understandable question: if the mistake seems obvious, do you still need an affidavit from a medical expert to pursue a malpractice claim?
In New Jersey, an affidavit of merit is not always required. A retained surgical object claim may fall within the state’s narrow “common knowledge” exception when ordinary jurors can recognize the negligence without expert testimony. However, that exception should not be assumed. The specific allegations against each provider determine whether an affidavit is necessary, and medical experts may still be needed to explain the injuries the object caused.
An object accidentally left behind is also different from a surgical clip, implant, or other device intentionally placed during treatment. The presence of an intentionally placed device does not, by itself, establish negligence.
Key Takeaways About Retained Surgical Object Claims in New Jersey
- Some retained surgical object claims qualify for New Jersey’s common knowledge exception to the affidavit of merit requirement.
- An affidavit generally must be provided within 60 days after the particular defendant files an answer to the lawsuit. A court may grant up to 60 additional days for good cause.
- The exception depends on whether jurors can evaluate the alleged negligence without specialized medical knowledge.
- Medical experts may still be needed to connect the retained object to an infection, additional surgery, permanent injury, or other harm.
- New Jersey’s discovery rule may affect when the two-year malpractice filing period begins.
When Can a Retained Surgical Object Claim Proceed Without an Affidavit of Merit?
New Jersey ordinarily requires an affidavit of merit in a medical malpractice lawsuit. This is a sworn statement from an appropriately qualified medical professional explaining that there is a reasonable probability the defendant’s care fell below accepted professional standards.
The affidavit generally comes after the lawsuit is filed. Under N.J.S.A. 2A:53A-27, it must ordinarily be provided within 60 days after the defendant files an answer. A court may grant one additional period of up to 60 days for good cause.
The common knowledge exception applies when jurors can recognize the alleged negligence using ordinary understanding and experience. In Hubbard v. Reed, the New Jersey Supreme Court held that an affidavit was unnecessary for a claim involving extraction of the wrong tooth. Jurors did not need dental training to understand that mistake.
The same reasoning may apply when a surgical sponge or another object that should have been removed is accidentally left inside a patient. The question is whether jurors can evaluate the specific defendant’s conduct without an expert explaining the applicable medical standard.
Why Doesn’t Every Retained Object Case Qualify for the Exception?
An unexpected surgical outcome is not automatically proof of negligence. Even when an object is found inside a patient, the circumstances may require medical explanation.
For example, the case may involve questions about:
- Whether the object was intended to remain in the body.
- Whether leaving a broken instrument fragment in place was a medical decision.
- Which procedure introduced the object.
- What responsibilities a particular surgeon, nurse, or other provider had during the operation.
- Whether the claim concerns an obvious failure to remove an object or a more complex treatment decision.
If proving a provider’s mistake requires an expert to explain accepted surgical practices, the common knowledge exception may not apply to that claim.
In Hubbard, the Supreme Court emphasized that the exception is narrow and that obtaining an affidavit remains the prudent approach even when a plaintiff expects to rely on common knowledge. Assuming an affidavit is unnecessary can put a claim at risk if the court later disagrees.
How Does the Rule Apply When Several Providers Were Involved?
Surgery usually involves a team. A retained object does not automatically establish that every person who participated in the operation was negligent.
An attorney will review the allegations against each proposed defendant. A claim involving an obvious mistake by one provider may qualify for the common knowledge exception, while a separate claim involving another provider’s supervision, treatment decisions, or professional responsibilities may require expert support.
Claims against a hospital also need a separate review. Naming a hospital does not automatically make an affidavit necessary or unnecessary. The analysis depends on the conduct alleged and the basis for holding the hospital responsible.
This review should happen early. Each defendant’s answer can start that defendant’s affidavit deadline, so the need for an affidavit should not be left unresolved while those deadlines approach.
Why Might Medical Experts Still Be Needed?
Recognizing a mistake and proving the harm it caused are separate questions. Jurors may understand that a sponge should have been removed but still need medical testimony to understand its effects.
An expert may be needed to explain whether the retained object caused:
- An infection or damage to nearby organs.
- The need for another operation.
- Persistent pain or physical limitations.
- Permanent nerve or tissue damage.
- A need for future medical treatment.
Medical testimony may also help distinguish injuries caused by the retained object from symptoms related to the original condition or surgery.
In Palanque v. Lambert-Woolley, the New Jersey Supreme Court applied the common knowledge exception to a claim involving a doctor’s misreading of laboratory reports. The decision reinforces that the exception depends on the particular mistake alleged and what jurors can understand without expert assistance.
The need for an expert on injuries or future care does not, by itself, mean an expert is also necessary to establish the underlying mistake. Each issue must be evaluated separately.
What Evidence Helps Prove a Retained Surgical Object Claim?
The evidence should connect the object to the procedure, support the allegations against the responsible providers, and document the resulting harm.
Important evidence may include:
- Operative reports, nursing notes, and surgical count sheets.
- Imaging showing the object’s location.
- Photographs or other documentation identifying the object.
- Records from the procedure in which the object was discovered or removed.
- Medical records documenting symptoms, complications, and additional treatment.
- Employment and financial records showing time missed from work and related losses.
The timeline matters. Records showing when symptoms began, when the object was discovered, and what treatment followed can help explain how the retained object affected the patient.
Patients should also tell their treating providers about ongoing symptoms and follow recommended care. Accurate medical records help document both recovery and any continuing limitations.
What Compensation May Be Available?
Compensation depends on the harm the retained object caused. The fact that an object was left behind does not establish the amount of compensation a patient can recover.
Recoverable damages in a New Jersey medical malpractice claim may include:
- Additional medical bills and the cost of corrective surgery.
- Future medical care supported by the evidence.
- Lost income.
- Reduced ability to earn a living.
- Pain and suffering.
- Lasting physical limitations.
A patient who develops a serious infection or needs extensive additional surgery may have different losses from someone whose object is discovered and removed before substantial complications develop. Medical and financial evidence help establish those differences.
How Long Do You Have to File a Claim in New Jersey?
New Jersey generally applies a two-year statute of limitations to medical malpractice claims. When an object remains hidden inside the body, the discovery rule may delay the start of that period.
In Fernandi v. Strully, the New Jersey Supreme Court considered a surgical wing nut left inside a patient. The Court held that, under those circumstances, the limitations period did not begin until the patient knew or had reason to know of the existence of her claim.
For a patient, this means the surgery date is not always the date that starts the filing period. The timing may depend on when the patient discovered, or reasonably should have discovered, the injury and facts suggesting someone’s fault.
Unexplained symptoms do not automatically settle that question. However, symptoms, imaging results, and conversations with providers can become important when determining when a patient reasonably should have recognized a possible claim.
The lawsuit deadline and the affidavit deadline are separate. A patient should have both evaluated promptly after discovering a retained object.
