What Counts as Medical Negligence and What Is a Bad Outcome?

A surgery that fails, a cancer that returns, a drug that causes a reaction listed on the label: none of these is medical negligence by itself. Medicine has bad outcomes without anyone doing anything wrong, and the law does not make a provider an insurer of results. What counts as medical negligence is narrower and more specific: the provider did something, or failed to do something, that a reasonably careful provider in the same specialty would not have, and that departure caused harm the patient would otherwise have avoided. Every case that comes through CLP’s medical negligence practice is screened against that definition first, and roughly as many bad outcomes fail it as pass.

The four elements you must prove

A medical negligence claim has the same four parts in Washington, DC, Virginia, and New York. There was a provider-patient relationship, which creates the duty. The provider breached the standard of care. The breach caused injury. The injury produced damages the law recognizes: medical costs, lost income, pain, disability, or death.

Each element has to be proven separately, and a case can fail at any one. The most common failures are the second and third. A provider who did exactly what the standard required is not liable for a bad result, and a provider who clearly fell below the standard is not liable if the patient would have ended up in the same place anyway.

The standard of care is a professional standard, not perfection

The standard of care is what a reasonably prudent provider in the same field would have done under similar circumstances with the information available at the time. It is set by the profession, not by hindsight, and it is proven through the testimony of another provider in that field. Virginia applies a statewide standard, so a rural emergency physician is measured against emergency physicians across the Commonwealth. A specialist is held to the standard of that specialty, and a generalist who takes on a specialist’s task is held to the specialist’s standard.

Clinical guidelines, hospital protocols, and drug labeling are evidence of the standard but do not define it. A provider can depart from a guideline with good reason and still meet the standard, and a provider can follow a guideline and still breach it if the guideline did not fit the patient. The question is always what a careful colleague would have done, which is why no medical negligence case proceeds without an expert, a requirement we explain in how do you prove medical malpractice in court.

A known complication is not negligence, but the response to it might be

Every procedure carries risks that occur even with perfect technique: infection, bleeding, nerve injury, anesthesia reactions. When one of those happens and the patient was told about it in advance, the complication itself is not negligence. What often is negligence is the failure to recognize and treat it. A post-surgical infection that was not caught because no one checked the wound or acted on the fever is a different claim from the infection itself. A retained sponge or a wrong-site surgery, by contrast, does not happen with proper care, and courts treat those events as negligence on their face.

Causation: the element that decides most cases

The plaintiff has to show that the breach, more likely than not, caused the harm. That is where most delayed diagnosis cases are won or lost, because a cancer that was missed for six months may or may not have been treatable differently six months earlier. The expert has to connect the breach to a specific worse result: a lost treatment option, a larger surgery, a lower survival probability, a permanent injury that earlier treatment would have prevented. Preexisting conditions complicate this, and the defense’s experts will argue the outcome was already determined. We take up the diagnosis cases separately in is a misdiagnosis or delayed diagnosis medical malpractice.

Informed consent is its own claim

A provider who performs a procedure competently can still be liable for failing to tell the patient about a material risk that then occurred. DC follows the rule from Canterbury v. Spence, a well-known decision from the federal appeals court in Washington, which asks what a reasonable patient would have wanted to know. Virginia and New York ask what a reasonable provider would have disclosed. In each, the plaintiff has to show that the undisclosed risk is the one that materialized and that a reasonable person, properly informed, would have declined the procedure. A signed consent form is evidence that a conversation happened, not proof of what was said.

Situations that usually are, and usually are not, medical negligence

• Usually negligence: operating on the wrong site, leaving an instrument inside the patient, prescribing a drug the chart shows the patient is allergic to, failing to act on a critical lab or imaging result that was received.
• Usually negligence: discharging a patient with unexplained chest pain or neurological symptoms without a workup.
• Usually not negligence: a listed complication that was disclosed and promptly treated.
• Usually not negligence: a treatment that failed when the choice among reasonable treatments was defensible.
• Depends on the facts: a diagnosis that was missed, a delayed referral, a birth injury, a medication dose at the edge of the range.
