Background
Ronald Roth sued NewYork-Presbyterian/Columbia University Medical Center and emergency physician Anthony Velasquez after a pulmonary embolism was diagnosed weeks after Roth visited the emergency department. Roth alleged that his presentation on November 10, 2015 required a CT pulmonary angiogram, or CTPA, and that failure to order the study delayed treatment and worsened his injuries. The hospital and physician moved for summary judgment, supporting their motion with medical records and expert opinions that the care complied with accepted practice.
Roth's expert, a general surgeon with extensive experience diagnosing pulmonary emboli, said Roth's risk factors, symptoms, electrocardiogram, and imaging should have prompted CTPA testing. Supreme Court found that opinion sufficient to create factual disputes and denied dismissal as to both defendants. On appeal, the First Department examined separately whether the expert was qualified, whether his conclusions answered the defense proof, and whether the factual assumptions underlying his opinion matched the contemporaneous record.
The Court’s Holding
The First Department allowed the claim against the hospital to proceed. It held that the general surgeon adequately explained his relevant experience and therefore could address the emergency standard of care. His opinion that Roth's Wells risk score and clinical presentation warranted further testing conflicted with the hospital experts' assessment and raised triable questions about departure and causation. The hospital's radiology expert also did not establish that a CTPA performed during the first visit would have failed to reveal the embolism later diagnosed.
The panel reached a different result for Dr. Velasquez. The record showed that his limited shift ended after he transferred Roth to the day team, which continued the workup and made the later diagnostic and discharge decisions. More importantly, Roth's expert assumed complaints and symptoms contradicted by the emergency medical services report, hospital chart, and Roth's own deposition. An expert opinion based on facts flatly inconsistent with the record is speculative and cannot defeat summary judgment. The court therefore dismissed the complaint against Velasquez while leaving the hospital claim for trial.
Key Takeaways
- Medical-malpractice claims against a hospital and an individual physician require defendant-specific proof; one may survive even when the other is dismissed.
- An expert may testify outside a formal specialty after explaining relevant practical experience, but the opinion must rest on facts supported by the record.
- Hospitals seeking summary judgment on delayed diagnosis should address whether the omitted test would have detected the condition at the earlier visit.
Why It Matters
For New York medical-malpractice lawyers, the decision is a useful map for constructing and attacking expert affirmations. Credentials alone do not decide admissibility, but the expert must connect experience to the disputed care. Counsel should reconcile every assumed symptom with ambulance records, triage notes, deposition testimony, and the timeline of which clinician controlled the patient's care. A contradiction on a central fact can eliminate an otherwise detailed opinion.
The ruling also matters to hospitals and emergency groups allocating responsibility across shifts. A physician who signs out a patient is not automatically responsible for every later decision, while an institutional claim may remain if other staff continued the allegedly inadequate workup. Early discovery should identify handoff times, decision authority, test ordering, and who approved discharge. Those details can narrow exposure before trial and help parties evaluate whether claims should be resolved differently for institutional and individual defendants.
The procedural allocation also affects settlement. Where the institutional defendant remains but a physician is dismissed, counsel should reassess agency theories, insurance layers, witness availability, and whether the remaining employees' conduct is adequately pleaded. Expert disclosures should distinguish the diagnostic judgment at each stage rather than refer collectively to the emergency department. Defense counsel should document not only what was done but also when responsibility passed to another clinician. Plaintiff's counsel should identify which later actor had the information and authority to order the disputed study. That timeline can determine whether the case presents a genuine conflict in medical judgment or an unsupported effort to attach later events to an earlier physician.
