The main idea is that patient identifiers must be stable, unique, and verifiable. A room number fails those criteria because it can change as patients move, and multiple patients can share a room at the same time. Relying on a room number increases the risk that the wrong patient is linked to a specimen or to treatments, which can lead to serious errors. In contrast, identifiers like the medical record number are intended to be unique to each patient and stay the same regardless of location. Names and dates of birth are useful but can be shared by others, so they’re best used in combination with another identifier. Standard safety practice is to confirm identity with at least two identifiers before collecting samples or administering care, and a room number does not meet that standard.
