HERSHEY, Pa. (AP) — A Pennsylvania hospital is apologizing for a letter it sent to patients with multiple sclerosis telling them to seek care elsewhere because of the recent departure of four doctors.

Penn State Health sent the apology letter Monday, telling patients that it remains committed to multiple sclerosis treatment at its hospital in Hershey despite the staffing issues. It says it has organized a team to help patients in the short-term and is looking to rebuild the department long-term.

On April 17, the health system sent a letter to 2,100 neurology patients advising them to seek alternate care options for multiple sclerosis.

Two of the departing doctors took new jobs, and two retired.
