Hospital vs. Doctor: Who Is Liable for Malpractice?

The short answer: it depends on the relationship between the doctor and the hospital, not just on where the harm happened. A hospital is generally liable for the negligence of its own employees, but many doctors who treat patients inside a hospital - emergency room physicians, surgeons, anesthesiologists, radiologists - are independent contractors rather than employees, which can shield the hospital from liability for that doctor's specific errors. There are two major exceptions that still let injured patients hold the hospital responsible: "ostensible agency" (the hospital made the doctor look like its own) and "corporate negligence" (the hospital's own systems and decisions were unsafe). Because the exact rules, terminology, and how courts apply them differ from state to state, this is one of the areas where getting a case reviewed early really matters.

Why "who employs the doctor" changes everything

Medical malpractice claims are built on ordinary negligence principles: the provider owed you a duty of care, breached that duty by falling below the accepted standard of care, that breach caused your injury, and you suffered real damages. But before you can even get to those questions for the hospital itself, you have to answer a threshold question: is the hospital legally responsible for the person who hurt you?

That threshold question turns on employment status, because of a long-standing rule of agency law called respondeat superior ("let the master answer"). Under this rule, an employer is vicariously liable for the negligent acts of its employees committed within the scope of their job. Applied to a hospital, this means:

• If a staff nurse gives the wrong medication dose, the hospital is typically liable, because nurses are almost always direct hospital employees.
• If a hospital-employed physician (increasingly common for hospitalists, some ER staffing models, and academic medical centers) makes a negligent diagnosis, the hospital is typically liable for that too.
• If an independent-contractor surgeon who simply has "privileges" to operate at the hospital makes a surgical error, the hospital may argue it is not liable, because the surgeon is not its employee - the surgeon works for their own practice or a physician group and merely uses the hospital's facility.

This is why patients are sometimes surprised to learn that suing "the hospital" is not automatically enough, and why malpractice cases against hospital-based care often name the doctor, the doctor's practice group or staffing company, and the hospital as separate defendants.

The independent-contractor problem

From a patient's point of view, the distinction between an employed doctor and an independent-contractor doctor is usually invisible. You are handed a gown, wheeled into a room, and treated by whoever the hospital schedules - you rarely negotiate or even see a contract. Yet hospitals have used the independent-contractor label for decades, particularly for emergency medicine, anesthesiology, radiology, and pathology groups, partly because it can limit the hospital's exposure to vicarious liability for those specialists' mistakes.

Courts recognized fairly early that this created an unfair gap for patients who had no realistic way to know, or choose, who was "really" treating them. That gap is largely filled by the doctrine described next.

Ostensible agency (apparent authority): when the hospital looks responsible even if it isn't the "employer"

Many states allow an injured patient to hold a hospital liable for an independent-contractor doctor's negligence under a theory usually called ostensible agency or apparent authority. The general idea, which appears in some form in the law of many states even though the exact test and label vary, is:

• The hospital held the doctor out to the public as if the doctor were part of the hospital (same logo on the scrubs, no clear disclosure of independent-contractor status, hospital billed for the services, doctor's office is inside the hospital, etc.), and
• The patient reasonably believed the doctor was a hospital employee or agent and relied on that belief in accepting treatment, rather than choosing that specific doctor personally.

Emergency room care is the classic setting for this doctrine, because patients typically do not select or vet their ER doctor - they simply accept whoever the hospital assigns. Some hospitals try to protect themselves with signed consent forms disclosing that certain physicians are independent contractors, not hospital employees. Whether that kind of disclosure defeats an ostensible-agency claim depends heavily on the state, the timing of the disclosure, and how clearly it was communicated - this is exactly the kind of fact-specific, state-by-state question a malpractice attorney needs to evaluate directly rather than something a general article can answer for your situation.

Corporate negligence: the hospital's own separate duties

Ostensible agency is about attributing someone else's (the doctor's) negligence to the hospital. Corporate negligence is a different and independent theory: it holds the hospital liable for its own failures as an institution, regardless of whether any individual doctor was negligent. This doctrine traces back to a foundational case, Darling v. Charleston Community Memorial Hospital, 33 Ill. 2d 326 (1965), which held that hospitals have their own responsibilities to patients beyond simply providing space for independent doctors to work - and it has since been adopted, in various forms, by courts in many other states. A commonly cited later decision, Thompson v. Nason Hospital, 527 Pa. 330 (1991), described the hospital's direct duties as generally including things like:

• Maintaining safe and adequate facilities and equipment.
• Selecting and retaining competent physicians (proper credentialing and privileging, and monitoring for known problems).
• Overseeing everyone who practices medicine within its walls.
• Adopting and enforcing adequate rules and policies to ensure patient safety and quality of care.

Examples of corporate negligence can include a hospital granting or renewing surgical privileges to a doctor despite red flags in that doctor's history, failing to have enough nursing staff on a unit to safely monitor patients, allowing broken or poorly maintained equipment to remain in use, or ignoring a pattern of complaints about a particular provider. Because this theory targets the hospital's own conduct, it can apply even when the treating doctor is unquestionably an independent contractor.

Not every state recognizes corporate negligence in exactly the same way or with the same list of duties, and some limit it to certain types of failures. Whether it applies to your situation, and how it is proven, is a state-specific and fact-specific question.

What to do if you suspect the harm involved a hospital and its doctors

1. Get and keep your complete medical records - including nursing notes, physician orders, consent forms, and any staffing or credentialing information you're entitled to request. These records are usually the only way to see who actually treated you and what their role was.
2. Note who you interacted with and when - names, titles, and whether anyone identified themselves as being with an outside group. Memory fades quickly, so write this down as soon as you can.
3. Look for signed consent or disclosure forms you may have received about independent-contractor physicians - keep copies of anything you signed.
4. Don't assume you know who is liable - let a malpractice attorney and, typically, a required expert medical review sort out whether the doctor, the hospital, or both are responsible; these cases usually involve more than one potential defendant.
5. Move quickly. Malpractice claims are subject to a statute of limitations that varies by state, and claims against a government-operated or public hospital can carry a much shorter notice-of-claim deadline that is sometimes measured in months rather than years. Confirm the specific deadlines that apply to your state and to each potential defendant as soon as possible - don't wait to "see how you feel" before checking.
6. Consult an attorney before signing anything or giving a recorded statement to a hospital's insurer, since these cases commonly involve multiple insurers with different interests.

Can the hospital talk privately with your doctors during the lawsuit?

In Washington, generally not without your knowledge and consent, or unless it goes through formal discovery. On October 1, 2026, the Washington Supreme Court applied that rule in Snyder v. Virginia Mason Medical Center to doctors who had left the hospital but whom the hospital was still obligated to defend and cover. The decision binds Washington courts only, and this page does not survey other states.

The rule comes from a 1988 case, Loudon v. Mhyre. When you sue over an injury, the defense must use the formal discovery rules to communicate with your doctors who are not parties to the case. Defense lawyers may still speak with them; the cases "merely require the defense to have those communications either with the plaintiff's knowledge and consent or through the formal discovery rules."

One narrow exception lets a hospital's lawyers have privileged conversations with current employees (and their functional equivalents), including a patient's doctors. When those conversations concern the patient's care, they are limited to the facts that gave rise to the claim.

Michael Snyder was left with permanent, disabling injuries after a January 2018 surgery in which, according to the court, it appears a catheter line passed through an artery. He sued the hospital in March 2019. Three doctors who took part in the surgery no longer worked there, but the hospital was contractually obligated to defend and indemnify them. The hospital communicated with them outside formal discovery, without Snyder's knowledge or consent. Its chief medical officer, who also sat on the hospital's quality improvement committee, traveled across the state to speak with one of them. The Supreme Court agreed with the lower courts that this broke the Loudon rule.

The hospital argued the exception should reach former employees it must defend. The court answered that the exception "was limited to the functional equivalent of current employees," that it had "explicitly declined to extend it" to former employees in an earlier case, and that the hospital had not shown that case was distinguishable or should be overruled.

The court also decided the following, and left some things open.

• It held that a patient does not have to prove the violation hurt the case. Prejudice is presumed, and the trial judge picks a remedy based on how much prejudice is shown.
• It sent the request for a default judgment on liability back to the trial court. It did not order one, and it did not decide that the hospital was negligent.
• It held that the hospital at least partially waived its quality improvement committee privilege by not screening that committee member from the lawsuit, and sent the dispute over those records back for further proceedings, including private review by the judge where necessary.
• It left open whether a judge could give a hospital permission for such private conversations, because this hospital did not ask for that permission before the contacts.

The full opinion is on the court's website. Justice Gordon McCloud wrote a dissent that would have held the rule does not apply to doctors whose allegedly negligent care is the basis of the claim. The case is back with the trial court, and no final remedy has been set.

The rule protects the privacy of your medical information and the independence of your doctors as witnesses. In a Washington case, ask your own lawyer at the start how the defense may contact your doctors. If you learn the hospital or its insurer has been in touch with one of them, tell your lawyer promptly and keep any letters, emails, or notes. Ask your lawyer before discussing the case with your doctors.

What this generally does not change

Regardless of which entity turns out to be liable, the basic building blocks of a malpractice case stay the same: you must show duty, a breach of the accepted standard of care (almost always requiring expert testimony), causation, and damages. Most malpractice claims that have merit are resolved through settlement rather than trial, and most malpractice attorneys handle these cases on a contingency-fee basis, commonly around one-third of any recovery, so you typically do not pay hourly fees out of pocket to have a claim evaluated. Whether your damages award or settlement would be capped, and by how much, also varies by state - some states cap certain types of malpractice damages and some do not, so this is another point to confirm locally rather than assume.

If you were injured and are unsure whether the hospital, the treating doctor, a physician staffing group, or some combination is responsible, that uncertainty is normal - it is exactly the kind of question a case evaluation is meant to sort out, and it is rarely something you can determine on your own from the outside.
