What Is Causation?

Causation is the connection between a person’s conduct and the harm that followed. In a medical malpractice claim, causation requires evidence that a healthcare provider’s negligent act or failure to act caused, or substantially contributed to, the patient’s injury. The analysis separates negligence from harm and examines whether the injury would have occurred without the alleged malpractice.

How Causation Works

Causation is tested by tracing the facts from the alleged medical error to the patient’s injury. The review may consider the patient’s condition before treatment, the care provided, and what happened afterward. Medical records can show changes in symptoms, treatment decisions, and the timing of the claimed harm.

A claim may involve more than one possible cause. Prior conditions, later treatment, or an independent medical event can affect the analysis. An expert witness may explain whether the provider’s conduct could have produced the injury and whether the claimed harm fits the medical evidence. The issue is not simply whether poor care occurred, but whether that care caused the loss being claimed.

From the Atlanta Auto Law team

When we review a medical malpractice claim, we compare the patient’s condition before and after the care at issue. We examine records, treatment timelines, and medical opinions to assess whether the alleged conduct connects to the claimed injury.

Causation in Practice: A Real-World Example

A patient receives a medication that conflicts with a documented allergy, then develops a serious reaction. Causation may depend on whether medical evidence connects the prescription decision to the reaction and resulting treatment.
