Redwood Eye Center in Vallejo, Calif., notified 16,055 patients after it learned its EMR vendor IT Lighthouse experienced a ransomware attack in September.
Here are four things to know:
1. IT Lighthouse hosts and stores Redwood Eye Center's EMR, and the Sept. 19 ransomware attack locked the server that stored some of the center's patient information.
2. Redwood Eye Center does not believe its patients' information was at risk of misuse, and it provided the notification out of an abundance of caution.
3. Potentially compromised information includes patient names, dates of birth, addresses, health insurance information and medical treatment information.
4. The center said it is taking steps to change its EMR vendor and enhance the security of its patient information.
