A nurse working a second overtime shift accidentally administered an oral medication via the patient's...

The error involved a misconnection of oral medication administered via an IV line, a serious safety event. The most effective and reliable solution is purchasing devices designed to prevent misconnections through physical incompatibility—known as forcing functions or mistake-proofing (poka-yoke) (The Joint Commission, Sentinel Event Alert #58, 2017; ECRI Institute, Preventing Misconnections, 2020). While reducing overtime (A) and education (C) help reduce errors generally, they rely on human behavior and are less foolproof. Labeling syringes (B) provides a warning but does not prevent the error mechanically. Engineering controls that physically prevent misconnections provide the highest level of safety and are mandated by regulatory bodies to address such sentinel events.
