Definition of the ME Preventability Used in the Study (Modified According to Hallas et al³⁹ and Linden-Lahti et al³⁷

ME Preventability	Description
Prevented	The error was prevented before it reached the patient.
Likely preventable	There was an existing procedure, operating model, or a guideline, and the error would have been prevented when acting according to it, but it was not followed.
Potentially preventable	There was no existing procedure, operating model, or guideline, but the error could have potentially been prevented from reoccurring with some medication safety development actions.
Unlikely preventable	Error or adverse drug event that was unlikely to be anticipated and would be difficult to prevent to reoccur even with new systemic defenses or other prospective medication risk management actions.
