In 2017, a project team from Mayo Clinic’s Integrity and Compliance Office began taking steps to stop the routine collection and storage of patient social security numbers (SSN) in the demographic field of the electronic health record (EHR). Mayo Clinic recognized the potential risk to patients if the number was compromised through unauthorized access or ransomware. The SSN was successfully removed from Mayo Clinic’s EHR in April 2022. Join Allyssa Stevens, Health Systems Engineer, April Carlson, Senior Manager of Data Security and Architecture, and Leah Mudler, Manager in Integrity and Compliance, along with host Jodi Grimm as they share project details, steps taken, and lessons learned for other health care organizations interested in taking this important step to help protect their patients’ information.
