A 34-year-old man is accused of attacking a nurse at UMass Memorial Medical Center--University Campus in Worcester Monday after police say he stabbed the nurse with a pen, shoving it through her lip.

An arrest warrant was issued this week for Loren Rosenburg, an Alford man who was a patient at the hospital on Monday, according to court records on file in Worcester Central District Court.

Rosenburg was at the Worcester hospital located on 55 N. Lake Ave. around 7:15 a.m. Monday while he was a patient, police reports said.

Authorities say Rosenburg became angry with the nurse. She asked Rosenburg what was wrong.

"You'll see," Rosenburg allegedly replied while grabbing a pen.

Rosenburg is accused of stabbing the nurse in her face several times. The nurse was able to block some of the strikes, but Rosenburg was able to jab the pen straight through the nurse's upper lip, police said.

The nurse will have to undergo plastic surgery to repair the wound, according to court records.

Officers for the hospital arrived at the scene to help the nurse. Police say Rosenburg kicked the officers when they responded.

Rosenburg was arraigned Thursday in Worcester Central District Court on charges of mayhem, assault and battery with a dangerous weapon, assault to maim and two counts of assault and battery on a police officer.

The Worcester Telegram & Gazette reports Rosenburg was released to his mother's custody and will undergo an undergo an outpatient psychiatric evaluation.

His lawyer told a judge that Rosenburg suffers from a seizure disorder and went to the hospital for treatment for seizures, the newspaper reports. A court psychologist believed Rosenburg's alleged actions could be because of the disorder, the Telegram & Gazette reported.

UMass released a statement Thursday, but did not any specifics about the allegations.

"At UMass Memorial Medical Center, we are fully committed to providing a safe workplace for all of our employees. We sympathize with all of the individuals involved in this incident and are constantly working to strengthen our Workplace Violence Prevention Program," said UMass Memorial Medical Center President Patrick Muldoon.

UMass said daily safety briefings are conducted to address any issues that may affect patients and employees. There is also a Violence Prevention Committee working on a comprehensive strategy to reduce the threat of violence in the workplace.

Non-violent crisis intervention training is available for employees and safety and security remains a key topic at UMass' new caregiver orientation.

The alleged attack came on the same week another Massachusetts healthcare organization announced new safety measures after authorities said a patient attacked a nurse with a knife earlier this year.

Harrington Healthcare installed metal detectors at emergency room entrances in the Southbridge and Webster locations. New visitor polices were also put in place.

The Harrington Hospital nurse, Elise Wilson, was working at the Southbridge location's emergency room when police say 24-year-old Conor O'Regan randomly began attacking her with a knife.

Wilson survived after several surgeries. O'Regan facing charges in court. Wilson's family are now fighting for lawmakers to pass "Elise's Law", which would require healthcare employers to develop, implement and review employee safety measures.
