Methodist Hospital went “on diversion” early Tuesday for the first time in its 100-plus years, sending ambulances that came to its doors to other hospitals.

A power surge knocked out Clarian Health’s computer system Monday afternoon, derailing the hospitals’ ability to access electronic health records for patients, said Clarian spokesman James Wide. Staff members at Methodist and Indiana University Hospital had to enter patients’ records by hand.

By about 1 a.m. Tuesday, a backlog of paperwork led Methodist and IU hospitals to stop accepting patients who arrived by ambulance. Walk-in patients were still accepted.

The diversion lasted until about 3 a.m., Wide said.
