A nurse discovers that a colleague has been altering patient documentation to hide a medication error that resulted in patient harm. What is the most appropriate initial action for the nurse to take?

When a nurse discovers a colleague has altered documentation to conceal a medication error that caused patient harm, the priority is to protect the harmed patient and others from further risk. The initial action must be immediate, formal reporting through the established chain of command, typically starting with the nurse manager or supervisor.

Do not confront the colleague directly. A private conversation can tip off the individual, allowing them to further alter or destroy evidence, coordinate a false narrative, or intimidate the reporter. This compromises any subsequent formal investigation and may place the reporting nurse in a vulnerable position.

Do not document suspicions or observations about a colleague's conduct in the patient's medical record. The patient chart is a legal document intended for clinical data, assessments, and interventions. Entering non-clinical, interpersonal accusations into the chart is inappropriate, creates a discoverable record that could complicate legal proceedings, and does not follow proper incident reporting protocol.

Do not wait for the colleague to self-report. Delaying action violates the nurse's ethical and legal duty to report unsafe practice promptly. The risk of ongoing harm to patients outweighs any personal or professional courtesy. The formal report should be made according to institutional policy, which often involves an incident report and notification of the direct supervisor, who will then initiate a confidential investigation.

The core principle is that patient safety is paramount. The reporting nurse's role is to provide factual information to the appropriate authority, not to investigate or resolve the situation independently. This approach ensures an objective, thorough review and protects all parties involved.
