Legal basis: Article 28 of the Basic Specification for Medical Records Writing refers to the medical instructions issued by doctors in medical activities. Medical orders are divided into long-term medical orders and temporary medical orders. The contents of the long-term medical order list include the patient's name, department, inpatient medical record number (or medical record number), page number, start date and time, long-term medical order content, stop date and time, doctor's signature, execution time and execution nurse's signature. The contents of temporary medical orders include the time of medical orders, the contents of temporary medical orders, the doctor's signature, the execution time and the execution nurse's signature. The contents and starting and ending time of medical orders shall be written by doctors. The contents of doctor's orders should be accurate and clear, and each doctor's order contains only one content, and the release time should be indicated, specifically to minutes. The doctor's advice cannot be changed. When cancellation is required, the word "cancellation" should be marked with red ink and signed. Under normal circumstances, doctors may not give oral orders. When oral medical advice is needed to rescue critically ill patients, nurses should repeat it. After the rescue, the doctor should fill the doctor's advice truthfully immediately.
