What is an adverse event in medical care?

An adverse event in medical care is defined as an injury resulting from the care provided, which is not directly attributable to the underlying disease of the patient. This encompasses a range of negative outcomes that may arise during the course of treatment, including complications, errors, or unexpected reactions to interventions. The emphasis is on the fact that the injury occurred because of medical care, highlighting the responsibility of healthcare providers to minimize such risks.

The other definitions do not accurately capture the essence of what constitutes an adverse event. A desired outcome resulting from treatment does not relate to injuries and is therefore not an adverse event. Anticipated injuries caused by an underlying disease imply that the harm is expected due to the patient's condition rather than the result of treatment, which is separate from the concept of adverse events. Lastly, an event that has no connection to medical intervention would not fit the definition of an adverse event, as it occurs outside the scope of healthcare provided. Thus, the correct understanding hinges on recognizing that the injury is a consequence of medical care itself, differentiating it from complications due to the disease itself or unrelated incidents.
