Extended information:

The long-term medical order includes the patient’s name, department, hospitalization record number (or medical record number), page number, start date and time, long-term medical order content, and stop date and time, physician signature, execution time, and execution nurse signature.

The contents of medical orders should be accurate and clear. Each medical order should contain only one content and indicate the time of issuance, which should be specific to the minute. Doctor's orders may not be altered. When cancellation is required, the word "Cancel" should be marked in red ink and signed.

Under normal circumstances, doctors are not allowed to issue oral medical orders. When oral medical orders need to be given to rescue critical patients, nurses should read them back.
