Health outcomes

Explanation:

Health outcome can be defined as the events that occurs after an intervention or care, these events can be measured clinically by physical examination, laboratory testing and imaging; self reported or observed.

Health outcomes are defined as changes in health of an individual or a group of individuals that result from specific healthcare interventions. Example of health outcome is improvement in a patient's eye sight after a cataract surgery.
