How do I show the doctor’s error actually caused my injury in Georgia?


Proving that a physician made a mistake is only half of a Georgia malpractice case. The other half, causation, asks whether that mistake is what produced the harm. A claimant must connect the breach of the medical standard of care to a specific injury, and Georgia courts treat that link as a separate element that has to be established with competent evidence.

The two questions causation answers

Georgia analyzes causation in two layers. The first is whether the error was a cause in fact of the harm, often framed as whether the injury would have happened anyway without the negligence. The second is proximate cause, which asks whether the injury was a reasonably foreseeable result of the error rather than something too remote to fairly charge to the physician. An error that breaks no chain to the patient’s outcome, even if careless, does not support recovery, because Georgia law requires harm that flows from the negligence itself.

Why expert testimony usually decides it

Medical causation is generally beyond the knowledge of an ordinary juror, so Georgia requires expert opinion to establish it in most malpractice cases. A qualified expert, admissible under O.C.G.A. § 24-7-702, typically explains to a reasonable degree of medical certainty how the deviation from accepted practice led to the result. Georgia also requires an expert affidavit to accompany the complaint under O.C.G.A. § 9-11-9.1, which means a supporting opinion is needed at the very start of the case, not just at trial.

Evidence that commonly supports the causal link includes:

  • Medical records showing the patient’s condition before and after the error.
  • Imaging, lab results, or pathology that tracks the progression of the injury.
  • Expert analysis ruling out other plausible causes.
  • Testimony tying the specific deviation to the specific outcome.

When other causes complicate the picture

Defendants often argue that an underlying disease, a later treating provider, or the patient’s own condition caused the harm. Under O.C.G.A. § 51-12-33, a jury can apportion the harm among the several actors who helped produce it, which is exactly why pinning down the physician’s own share of the causation is so important. A strong causation case anticipates these alternatives and addresses them through the records and expert opinion rather than leaving them unanswered.

The bottom line

In Georgia, showing causation means proving, through qualified expert testimony and the medical record, that the physician’s deviation from accepted practice produced the injury and that the injury was a foreseeable consequence of the error. Without that link, a deviation alone does not create a recoverable claim.
