Whenever a medication error occurs, it should be documented in an incident report. The purpose of the incident report is to document the details of the event, including what happened, why it happened, and what was done to prevent it from happening again. Incident reports are not part of the client's medical record and are not used for disciplinary action. They are used for quality improvement and risk management purposes.
