SAN DIEGO -- When Mary Prehoden gets dressed for work every morning, her eyes lock on the bite-shaped scar on her chest.
It's a harsh reminder of one of the worst days of her life. Prehoden, a nurse supervisor at Scripps Mercy Hospital San Diego, was brutally attacked last year by a schizophrenic patient who was off his medication. He lunged at her, threw her to the ground, repeatedly punched and kicked her, and bit her so hard that his teeth broke the skin and left her bleeding.
The incident lasted about 90 seconds, but the damage lingers.
"Even if I didn't have a scar, the scar is in your head," said Prehoden, 58. "That stays with you for the rest of your life."
Violence against health care workers is common -- and some say on the rise.
According to the Occupational Safety and Health Administration, workplace violence is four times more common in health care settings than in private industry on average, yet it still goes underreported. Patients account for about 80% of the serious violent incidents reported, but stressed-out family and friends also are culprits. Co-workers and students caused 6% of the incidents.
In a 2018 poll of about 3,500 emergency room doctors conducted for the American College of Emergency Physicians, nearly 70% said violence in the emergency department has increased in the past five years.
About 40% of the doctors believed the majority of assaults were committed by psychiatric patients, and half said the majority were committed by people seeking drugs or those under the influence of drugs or alcohol.
In California, a state law requires hospitals to adopt workplace violence prevention plans and report the number and types of attacks to the state. The state then compiles the data into annual reports.
In the first full report, 365 hospitals tallied 9,436 violent incidents during the 12-month period that ended Sept. 30, 2018, ranging from scratchings to stabbings. Workers were punched or slapped in one-third of the assaults and were bitten in 7% of cases.
