Final answer:
When a patient's medical record is stored in two locations, a unique identifier such as a medical record number is used to indicate this. This identifier is attached to the patient's record in both locations, allowing for easy cross-referencing and access to the information.
Step-by-step explanation:
When a patient's medical record is stored in two locations, it is usually indicated by using a unique identifier such as a medical record number or an identification code. This identifier is attached to the patient's record in both locations, allowing healthcare professionals to easily cross-reference and access the information they need.
For example, let's say a patient's medical record is stored in a hospital's electronic health record system as well as in a specialized research database. The unique identifier would be used in both systems to link the patient's record and ensure that the data is consistent and accessible.
Using a unique identifier for patients' medical records in multiple locations helps to maintain data integrity, facilitate information exchange, and improve patient care.
