Violence: Occupational Hazards in Hospitals


Today, more than 5 million U.S. hospital workers from many occupations perform a wide variety of duties. They are exposed to many safety and health hazards, including violence. Recent data indicate that hospital workers are at high risk for experiencing violence in the workplace. According to estimates of the Bureau of Labor Statistics (BLS), 2,637 nonfatal assaults on hospital workers occurred in 1999—a rate a rate of 8.3 assaults per 10,000 workers. This rate is much higher than the rate of nonfatal assaults for all private-sector industries, which is 2 per 10,000 workers.

Several studies indicate that violence often takes place during times of high activity and interaction with patients, such as at meal times and during visiting hours and patient transportation. Assaults may occur when service is denied, when a patient is involuntarily admitted, or when a health care worker attempts to set limits on eating, drinking, or tobacco or alcohol use.

What is workplace violence?

Workplace violence ranges from offensive or threatening language to homicide. NIOSH (National Institute for Occupational Safety and Health) defines workplace violence as violent acts (including physical assaults and threats of assaults) directed toward persons at work or on duty.

Examples of violence include the following:

  • Threats: Expressions of intent to cause harm, including verbal threats, threatening body language, and written threats.
  • Physical assaults: Attacks ranging from slapping and beating to rape, homicide, and the use of weapons such as firearms, bombs, or knives.
  • Muggings: Aggravated assaults, usually conducted by surprise and with intent to rob.

These circumstances of hospital violence differ from the circumstances of workplace violence in general. In other workplaces such as convenience stores and taxicabs, violence most often relates to robbery. Violence in hospitals usually results from patients and occasionally from their family members who feel frustrated, vulnerable, and out of control.

Who is at risk?

Although anyone working in a hospital may become a victim of violence, nurses and aides who have the most direct contact with patients are at higher risk. Other hospital personnel at increased risk of violence include emergency response personnel, hospital safety officers, and all health care providers.

Where may violence occur?

Violence may occur anywhere in the hospital, but it is most frequent in the following areas:

  • Psychiatric wards.
  • Emergency rooms.
  • Waiting rooms.
  • Geriatric units.

What are the effects of violence?

The effects of violence can range in intensity include the following:

  • Minor physical injuries.
  • Serious physical injuries.
  • Temporary and permanent physical disability.
  • Psychological trauma.
  • Death.

Violence may also have negative organizational outcomes such as low worker morale, increased job stress, increased worker turnover, reduced trust of management and coworkers, and a hostile working environment.

What are the risk factors for violence?

The risk factors for violence vary from hospital to hospital depending on location, size, and type of care. Common risk factors for hospital violence include the following:

  • Working directly with volatile people, especially if they are under the influence of drugs or alcohol or have a history of violence or certain psychological diagnosis.
  • Working when understaffed—especially during meal times and visiting hours.
  • Transporting patients.
  • Long waits for service.
  • Overcrowded, uncomfortable waiting rooms.
  • Working alone.
  • Poor environmental design.
  • Inadequate security.
  • Lack of staff training and policies for preventing and managing crises with potentially volatile patients.
  • Drug and alcohol abuse.
  • Access to firearms.
  • Unrestricted movement of the public.
  • Poorly lit corridors, rooms, parking lots, and other areas.

Prevention Strategies for Employers

To prevent violence in hospitals, employers should develop a safety and health program that includes management commitment, employee participation, hazard identification, safety and health training, and hazard prevention, control, and reporting. Employers should evaluate this program periodically.

Although risk factors for violence are specific for each hospital and its work scenarios, employers can follow general prevention strategies.

Environmental Designs:

  • Develop emergency signaling, alarms, and monitoring systems.
  • Install security devices such as metal detectors to prevent armed persons from entering the hospital.
  • Install other security devices such as cameras and good lighting in hallways.
  • Provide security escorts to the parking lots at night.
  • Design waiting areas to accommodate and assist visitors and patients who may have a delay in service.
  • Design the triage area and other public areas to minimize the risk of assault.
  • Provide staff restrooms and emergency exits.
  • Install enclosed nurses’ stations.
  • Install deep service counters or bullet-resistant resistant and shatterproof glass enclosures in reception areas.
  • Arrange furniture and other objects to minimize their use as weapons.

Administrative Controls:

  • Design staffing patterns to prevent personnel from working alone and to minimize patient waiting time.
  • Restrict the movement of the public in hospitals by card-controlled access.
  • Develop a system for alerting security personnel when violence is threatened.

Behavior Modifications:

  • Provide all workers with training in recognizing and managing assaults, resolving conflicts, and maintaining hazard awareness.

Dealing With the Consequences of Violence

Violence may occur in the workplace in spite of preventive measures. Employers should be prepared to deal with the consequences of this violence by providing an environment that promotes open communication and by developing written procedures for reporting and responding to violence. Employers should offer and encourage counseling whenever a worker is threatened or assaulted.

Safety Tips for Hospital Workers

Watch for signals that may be associated with impending violence:

  • Verbally expressed anger and frustration.
  • Body language such as threatening gestures.
  • Signs of drug or alcohol use.
  • Presence of a weapon.

Maintain behavior that helps diffuse anger:

  • Present a calm, caring attitude.
  • Don’t match the threats.
  • Don’t give orders.
  • Acknowledge the person’s feelings (for example, “I know you are frustrated”).
  • Avoid any behavior that may be interpreted as aggressive (for example, moving rapidly, getting too close, touching, or speaking loudly).

Be alert:

  • Evaluate each situation for potential violence when you enter a room or begin to relate to a patient or visitor.
  • Be vigilant throughout the encounter.
  • Don’t isolate yourself with a potentially violent person.
  • Always keep an open path for exiting—don’t let the potentially violent person stand between you and the door.

Take these steps if you can’t defuse the situation quickly:

  • Remove yourself from the situation.
  • Call security for help.
  • Report any violent incidents to your management.


All hospitals should develop a comprehensive violence prevention program. No universal strategy exists to prevent violence. The risk factors vary from hospital to hospital and from unit to unit. Hospitals should form multidisciplinary committees that include direct-care staff as well as union representatives (if available) to identify risk factors in specific work scenarios and to develop strategies for reducing them. All hospital workers should be alert and cautious when interacting with patients and visitors. They should actively participate in safety training programs and be familiar with their employers’ policies, procedures, and materials on violence prevention.
