Because patients commonly experience adverse outcomes, it is important to distinguish adverse outcomes as a result of medical care from morbidity and mortality that patients suffer as a consequence of their underlying medical conditions.
The former are known as adverse events and has been defined by the Institute for Healthcare Improvement as follows:
Unintended physical injury resulting from medical care that requires additional monitoring, treatment, or hospitalization, or that results in death.
Adverse events may be preventable or non-preventable like harm from their medical care in the absence of any errors (i.e., from accepted complications or medication side effects).
