Teaching Hospital Liability and Resident Supervision

As a major academic medical center, Mount Sinai trains surgical residents and fellows. This creates a unique liability issue: who actually performed your surgery?

In teaching hospitals, surgical procedures are often performed by residents (doctors-in-training) under the supervision of an attending surgeon. The attending surgeon may be: - Present in the OR for the critical portions of the surgery. - Available but not present — leaving the resident to perform portions of the surgery unsupervised. - Concurrent surgery — supervising two surgeries in different operating rooms simultaneously. [Link to: /surgical-errors/concurrent-surgery]

Under New York law and ACGME (Accreditation Council for Graduate Medical Education) regulations, attending surgeons must provide appropriate supervision of residents. If a resident commits a surgical error because they were inadequately supervised, both the resident and the attending surgeon (and the hospital) may be liable. [Link to: /surgical-errors/resident-supervision]

In your malpractice case, the medical records and operative reports should identify who performed each portion of the surgery. If the records are unclear, this itself may be evidence of substandard care. [Link to: /surgical-errors/accessing-records]

The 90-Day Notice of Claim Question

An important legal distinction: Mount Sinai hospitals are private, non-profit hospitals — not municipal hospitals. This means: - The General Municipal Law § 50-e Notice of Claim requirement (90-day deadline) does not apply. - The statute of limitations is 2.5 years from the date of the surgical error under CPLR § 214-a. - The continuous treatment doctrine may extend the deadline if you continued receiving treatment from the same surgeon for the same condition.

However, if your surgery was at a facility affiliated with NYC Health + Hospitals (a municipal hospital), the 90-day Notice of Claim DOES apply. An experienced attorney can determine the correct deadlines for your specific case. [Link to: /surgical-errors/statute-of-limitations]

Building a Surgical Error Case Against Mount Sinai

To build a successful surgical error case against Mount Sinai, MDLaw Firm will:

1. Obtain complete medical records: Pre-operative records, operative reports, anesthesia records, nursing notes, post-operative records, imaging studies, and pathology reports. Mount Sinai uses the Epic electronic medical record system.

2. Review the operative report: The operative report — dictated by the surgeon after the procedure — describes what was done during surgery. Expert review can identify discrepancies between the report and the actual course of events.

3. Engage surgical experts: Board-certified surgeons in the relevant specialty review the records and provide opinions on whether the standard of care was breached and whether the breach caused the injury.

4. Identify all liable parties: The surgeon, anesthesiologist, nurses, residents, attending physicians, and Mount Sinai as the hospital corporation (under respondeat superior for employees, and negligent supervision/credentialing).

5. Establish causation and damages: Expert testimony linking the surgical error to the injury, and documentation of all medical expenses, lost wages, pain and suffering, and future care needs.

6. File the lawsuit with a certificate of merit: Under CPLR § 3012-a. [Link to: /medical-malpractice/certificate-of-merit]

New York Statute of Limitations

Under CPLR § 214-a, the statute of limitations for medical malpractice in New York is 2.5 years from the date of the negligent act (typically the date of surgery). The continuous treatment doctrine may extend the deadline if you continued receiving treatment from the same provider for the same condition. The foreign object exception (CPLR § 214-a(2)) gives you 1 year from the date the object was discovered (or should have been discovered) to file a claim for a retained surgical object — even if more than 2.5 years have passed. Contact a lawyer as early as possible to preserve evidence. [Link to: /surgical-errors/statute-of-limitations]
