What is an adverse event?

An adverse event is defined as an unexpected outcome that occurs as a result of medical care. This definition encompasses various situations in healthcare settings where a patient suffers harm that is not attributable to the underlying condition being treated.

The mention of an accident in a hospital setting aligns with this definition, as it can indeed lead to unexpected outcomes that harm patients. Therefore, both accidents that occur in a hospital setting and unexpected outcomes resulting from medical care contribute to the concept of an adverse event.

By combining both aspects, the correct answer reflects a broader understanding of what constitutes an adverse event. It highlights the importance of recognizing these incidents in healthcare to improve patient safety and care quality.
