What Is Causation?
Causation is the connection between a healthcare provider’s conduct and a patient’s injury or loss. In a medical malpractice claim, causation requires evidence that the provider’s act or omission contributed to the harm. A medical condition alone does not establish causation because the claim must connect the provider’s conduct to the claimed result.

Key Takeaways About Causation
- Causation connects conduct to a claimed injury.
- Medical conditions alone do not prove causation.
- Timing does not automatically establish a legal connection.
How Causation Works

Causation works by linking the provider’s conduct to the patient’s claimed harm. The analysis examines what happened before, during, and after the treatment. Medical records can show the patient’s condition, the care given, and changes that followed.

The analysis also considers whether another condition could explain the injury. A prior illness may affect the connection without eliminating it. Testimony from a qualified medical professional may explain how the conduct affected the patient’s condition and whether the claimed harm followed from that conduct. The evidence must support a logical connection between the care and the result.

From the Atlanta Auto Law team
When we review a medical malpractice matter, we compare the claimed injury with the treatment record and the patient’s medical history. We look for evidence that connects the provider’s conduct with the harm. We also examine other possible causes so the analysis does not rely on timing alone.
Causation in Practice: A Real-World Example
A patient develops a serious infection after a procedure, and the records show that warning signs were not addressed. Causation may depend on medical evidence explaining whether earlier action would likely have changed the patient’s outcome.
