There are several methods and practices employed to protect patient records in epidemiological studies:
1. De-identification: Removing or coding personal identifiers from data sets so that individuals cannot be readily identified. 2. Encryption: Using encryption technologies to secure data during transmission and storage. 3. Access Control: Limiting access to sensitive information to only those who need it for research purposes. 4. Informed Consent: Ensuring that participants are fully aware of how their data will be used and have given their explicit permission.
