What ensures that only authorized individuals can access and modify health data?

The correct answer is related to the concept of ensuring that only authorized individuals can access and modify health data. Data integrity measures play a critical role in maintaining accurate and secure health information. These measures include controls and processes that guarantee that the data is entered, stored, and retrieved correctly without unauthorized alterations. By establishing protocols for data entry, validation processes, and use of encryption, organizations can monitor and safeguard health data against unauthorized access and modifications.

While access restrictions serve a similar function by limiting user access based on roles and permissions, they specifically govern who can see or alter the data, rather than directly ensuring the data's accuracy and trustworthiness. Audit trails are important for tracking who accessed the data and what modifications were made, whereas periodic review involves regularly assessing data and policies but does not directly protect the data itself. Thus, data integrity measures are foundational in establishing the trustworthiness of health data management.
