MLive reports that an undisclosed number of Hurley Medical Center employees' and retirees' names and Social Security numbers were mistakenly released when an email was sent on May 13, 2014 to explain an error that had been made in calculating some co-payments for the center's health care plan (h/t PHIprivacy.net).

An attachment included with the email held the affected employees' and retirees' names and Social Security numbers.

"We take our obligation to protect our employees' personal information very seriously and sincerely regret this incident," Hurley president and CEO Melany Gavulic said in a statement. "Immediate steps were taken to reemphasize our policies already in place and conduct refresher training on those privacy policies."

While there's no indication at this point that any of the information was misused, all those affected are being offered free access to identity protection services from First Watch Technologies.
