Portland, OR -

Officials at a Portland hospital had to draft a hurried plan of action to avoid losing funding after a federal agency determined the hospital failed to thoroughly investigate a series of complaints from patients who accused an emergency room nurse of sex abuse.

The Oregonian reports it obtained the findings after a public records request.

The investigation revealed how Legacy Emanuel Medical Center staff repeatedly bungled their handling of the complaints against nurse Jeffrey N. McAllister.

The hospital fired McAllister a year ago. He has since been indicted and accused of sexually abusing 10 patients at the hospital between October 2009 and April 2013. He has pleaded not guilty to the charges.

The hospital hasn't disciplined any of its employees who handled the complaints against McAllister.
