Patient safety is defined as the “absence of adverse events” and often extended to include the activities involved in preventing adverse events, including adherence to quality standards and access to healthcare services
- Adverse event (AE) — A harmful event that is due to the treatment rather than the disease; it may be preventable or non-preventable
- Preventable adverse event (PAE)— An adverse event that is preventable (i.e. caused by an error or a mistake)
- Critical incident — An event that might result in an adverse event or clearly increases the probability of an adverse event
- Error — An action or omission that entails deviating from the plan, following a wrong plan, or no plan. Whether harm arises from this is irrelevant for the definition of an error. Note that Reason’s definitions state that error is involves failures of execution of a plan, whereas mistakes refer to errors of planning.
- Near miss — An error without harm that could have resulted in harm
