Michigan system IT outage affects billing, EHR

Grand Blanc, Mich.-based McLaren Health Care's billing system and EHR was affected by a computer network shutdown after its IT security team found suspicious activity during routine monitoring, Detroit Free Press reported Sept. 5. 

The health system had to shut down its computer network at 14 of its hospitals to investigate the incident. One employee told the publication that staff had to use personal cellphones to communicate during the shutdown.

McLaren did not disclose which systems were affected, whether patients' protected health information was compromised or when the security incident was identified.
