Answer:
C. Information stored in the system was inputted incorrectly by an employee.
Step-by-step explanation:
Hospital Information System (HIS) has greatly improved the quality of care being given to patients. The system serves as a "source" for the patient's health history; thus, it is very important to secure it.
However, as mentioned above, HIS is not that perfect. Some of the employees may incorrectly input information on the system, for example if the healthcare professional is not fully trained to handle electronic health records. It is then essential for it to be updated and thoroughly checked.
