What term describes errors resulting from a failure to complete a planned action as intended?

The term that is most accurately described by errors resulting from a failure to complete a planned action as intended is an execution error. Execution errors occur when the intended action is not carried out properly, which could be due to various factors such as oversight, distraction, or a lapse in following protocols. This type of error emphasizes the importance of not just the planning of a task but also the execution of that plan – highlighting that even with good intentions, failure to perform the planned action can have significant implications, especially in clinical settings.

Omission errors specifically refer to the not doing part of actions that were intended to be taken, while commission errors involve performing an act that is incorrect or harmful. Diagnostic errors relate to inaccuracies in identifying a condition or problem. Execution errors encompass both the failure to carry out intended actions as well as the context in which those actions should have been performed, making it the most fitting term within the context of the question.
