A power outage that affected the Henry Ford Health System computer systems was resolved Thursday afternoon.
"All computer applications affected by today’s power issue at our data center are fully restored," officials said in an email shortly after 4 p.m.
The electrical problem happened at the healthcare provider's data center about 7:40 a.m., officials said.
"We encountered some minor delays in patient care, and complex, non-emergent procedures were delayed until the appropriate applications are restored," David Olejarz, a spokesman for the nonprofit, said in an email during the outage.
"During a power issue, our employees are trained to perform services using standard downtime procedures, which involve taking information down on paper to ensure patient care information is recorded and updated," he said. "Patients are being seen as scheduled. We are following up with patients requesting future appointments."
Last month, hospital officials said about 18,470 patients had their health information either viewed or stolen in a data breach.
Based in Detroit and established in 1915 by auto pioneer Henry Ford, Henry Ford Health System owns and operates six hospitals in Metro Detroit. It has more than 30,000 employees and has revenue of nearly $6 billion.
