In most cases, the answer to whether you sue the doctor or the hospital for malpractice is both. The two face liability through different legal theories, and figuring out which one actually caused your injury usually takes months of records review and expert analysis. Naming both from the start protects your claim if the doctor’s employment status turns out to be different than you assumed, or if institutional failures contributed to the harm in ways that weren’t obvious at intake. Which defendant ultimately pays depends on the doctor’s relationship with the hospital, the type of error involved, and whether the hospital’s own systems played a role.
When the Doctor Is Personally Liable
A doctor is individually responsible when their personal conduct falls below the accepted standard of care, meaning what a reasonably competent physician in the same specialty would have done in similar circumstances. A surgeon operating on the wrong site, a radiologist misreading imaging, a specialist failing to order a test any peer would have ordered: each is direct personal liability, and it attaches to the physician regardless of where the treatment happened.
The doctor’s employment status then shapes who else you can bring into the case. Many physicians, particularly surgeons, anesthesiologists, radiologists, and emergency room doctors, work as independent contractors rather than hospital employees. An independent contractor generally runs their own practice, carries their own malpractice insurance, and exercises independent judgment over patient care.1National Center for Biotechnology Information (NCBI). Responsibility for the Acts of Others When an independent contractor injures you, the hospital’s first move is usually to argue it has no liability for that doctor’s actions, and your claim in that scenario centers on the individual physician and their insurer.
Patients almost never know which category their doctor falls into. Nothing in the ordinary hospital experience signals it. You check in, get treated by whoever is assigned, and reasonably assume the whole operation is one entity. The law accounts for that, but only through a specific doctrine covered further down.
When the Hospital Is Liable
Hospitals face liability along two separate tracks: one for the mistakes of their employees, and one for the hospital’s own failures as an institution.
Vicarious Liability for Employee Negligence
Under respondeat superior, a hospital is responsible for the negligent acts of its employees committed within the scope of their duties. This covers nurses, technicians, employed physicians, and non-clinical staff whose errors harm a patient. The liability is automatic. It does not matter whether the hospital hired, trained, and supervised carefully. If the employee was negligent on the job, the hospital pays.1National Center for Biotechnology Information (NCBI). Responsibility for the Acts of Others
That is why employment status is so often the pivotal question. A negligent nurse is almost always a hospital employee, which makes the hospital vicariously liable. A negligent surgeon may be an independent contractor, which can shield the hospital from this theory entirely.
Corporate Negligence
A hospital can also be liable for its own institutional failures even when no individual employee was negligent. Corporate negligence claims target things like hiring unqualified physicians, failing to verify credentials, understaffing units to the point where errors become predictable, neglecting equipment maintenance, and failing to implement basic safety protocols. The focus is not on any one person’s mistake but on the environment the hospital built. A nurse assigned to a 16-hour shift with double the recommended patient load is working in conditions where errors are predictable, and the institution bears responsibility for creating them.
Corporate negligence is especially useful when the individual provider’s care was borderline. A judgment call that might not rise to malpractice on its own can become actionable when systemic failures made a bad outcome more likely.
Ostensible Agency and the Emergency Room Problem
The independent contractor label does not always protect the hospital. Under ostensible agency, sometimes called apparent authority, a hospital can be liable for an independent contractor doctor’s negligence if the hospital held the doctor out as its own and the patient reasonably relied on that appearance.1National Center for Biotechnology Information (NCBI). Responsibility for the Acts of Others
Emergency rooms are the classic setting. You walk into a hospital ER, get treated by whichever physician is on duty, and have no meaningful role in choosing your doctor. Nothing in that experience suggests the ER physician is actually billing through a separate professional company. Courts have repeatedly held that a hospital presenting itself as a full-service provider, where the patient looks to the institution rather than to a specific doctor, cannot hide behind the independent contractor label.
Courts weigh whether the hospital did anything to suggest the doctor was part of its team, whether the patient had any reason to seek out that particular doctor independently, and whether the patient had a real chance to pick a different provider. The more the hospital controls the experience and the less choice the patient has, the stronger the ostensible agency argument.
Suing Both at Once
When both the doctor and the hospital contributed to the injury, both can be named in the same lawsuit, and that is the common situation. A surgeon may commit a clear error while the hospital also failed to provide adequate nursing support during recovery, missed warning signs in post-operative monitoring, or assigned the surgeon a case outside their credentialing. Each defendant carries a share of responsibility.
Under joint and several liability, when multiple defendants cause a single injury, the injured patient can collect the entire judgment from any one of them. If one defendant cannot pay, the others cover the full amount, and a defendant who pays more than its proportional share can seek reimbursement from the others. The point is to keep the patient from being undercompensated because one defendant is judgment-proof or underinsured.
Many states have modified this rule, and some now divide damages strictly according to each defendant’s percentage of fault. That directly affects strategy. In a pure several liability state, suing both the doctor and the hospital is not just prudent; it is often the only way to collect what you are owed if one party’s fault share is larger than that party’s ability to pay.
A Note on Informed Consent
Informed consent claims work on a different theory: not that the treatment was performed negligently, but that the doctor failed to adequately explain the risks, benefits, and alternatives, and that you would have declined the procedure with full information.2National Center for Biotechnology Information (NCBI). The Parameters of Informed Consent These claims typically target the treating physician, because the duty to explain risks sits with the doctor proposing the treatment. A hospital can face related liability if its consent systems failed, its policies were inadequate, or its staff proceeded without confirming that consent existed.
Government Hospitals Change the Question
If the injury happened at a VA hospital, a military treatment facility, or a federally funded community health center, the choice between doctor and hospital largely disappears. You cannot walk straight into court. Federal law requires you to first file an administrative claim with the responsible agency, and the claim must state a specific dollar amount for your damages. For VA claims, you can use Standard Form 95 or any written submission that includes a detailed description, the total amount claimed, and your signature.3U.S. Department of Veterans Affairs. Claims Under the Federal Tort Claims Act
The administrative claim must reach the agency within two years of when the claim accrued. The agency then has six months to respond. If it denies the claim or does not act within that six-month window, you can file suit in federal court.4Office of the Law Revision Counsel. 28 U.S. Code 2675 – Disposition by Federal Agency as Prerequisite Skipping the administrative step bars the lawsuit, and courts enforce that strictly.
You also generally cannot sue the individual federal doctor or nurse who treated you. Federal law makes a claim against the United States the exclusive remedy for negligence by federal employees acting within the scope of their duties.5Office of the Law Revision Counsel. 28 U.S. Code 2679 – Exclusiveness of Remedy At a VA hospital, the question in the headline is moot: the defendant is the federal government.
Why the Choice Is Rarely Just One
Medical malpractice cases are expensive to pursue. A single case usually needs one or more medical experts to review records and testify, and expert fees in complex matters can run into the tens of thousands of dollars. Filing fees, deposition costs, and record charges add to that. Most attorneys work on contingency and advance those costs, which means the decision of whom to name is also a decision about where the resources go.
Naming the right defendants at the outset avoids burning money on theories that will not hold up. Naming too few risks missing the party with deeper insurance coverage and greater actual responsibility for what happened. That balance is why the standard answer for most patients is not doctor or hospital but doctor and hospital, with the case narrowing as the facts about employment, credentialing, staffing, and institutional systems come into focus.
