McLaren Health Care confirmed that the disruption to their information technology and phone systems on Tuesday was the result of a criminal cyberattack. They said their IT team is working with cybersecurity experts to analyze and mitigate the impacts. So far, they have not determined if any patient or employee data was compromised. You should plan on attending appointments as normal unless you are contacted about a change. Due to the technology outage, McLaren requests that you bring: A list of current medications or prescription bottles… Printed physician orders for imaging studies or treatments… Printed results of recent lab tests available in the patient portals… and a list of allergies.
