Workplace Violence and Nursing Profession
Workplace Violence
Workplace violence is defined as “violent acts (including physical
assaults and threats of assaults) directed towards persons at work or on duty”
(National Institute of Occupational Safety and Health [NIOSH], 2002). Most
workplace violence falls into one of four categories.
Four Categories of Work place Violation
Type I (Criminal Intent): Results while a criminal activity (eg, robbery) is being committed
and the perpetrator has no legitimate relationship to the workplace.
Type II (Customer/Client): The perpetrator is a customer or client at the workplace (eg,
health care patient) and becomes violent while being served by the worker.
Type III (Worker-on-Worker): Employees or past employees of the workplace are the perpetrators
in this case,
Type IV (Personal Relationship): The perpetrator in this case usually has a personal relationship
with an employee (eg, domestic violence in the workplace).
Homicide as Major Cause of Death
Homicide has remained among the top three causes of death in the
workplace since 1990. According to the Bureau of Labor Statistics (BLS),
workplace violence is the third leading cause of occupational injury death
among all workers and the leading cause among women.
Workplace homicides have
declined from a high of 1,080 in 1994 to 609 in 2002; on average 846 workers
per year have died as a result of homicide since 1992. Notably, 80% of
workplace homicides involve the use of a firearm (NIOSH, 1996).
Fatal and Non Fatal Assault
Nonfatal assaults are much more common than fatal assaults.
Although both share many of the same risk factors (eg, contact with the public,
working with volatile persons, working in small numbers, and working in
community based settings) health care rather than retail workers represent the
majority of victims of nonfatal workplace violence.
According to the Department
of Justice’s National Crime Victimization Survey (NCVS), 1.9 million incidents
of workplace violence occurred in the workplace each year from 1992-1996 (
Warchol , 1998).
Twelve percent of all victims reported physical injuries; 6%
of the workplace crimes resulted in injury that required medical treatment, and
only 44% of all incidents were reported to the police.
Reporting of Work Place Violation
Workplace violence is a documented occupational hazard in the
health care and service sectors (NIOSH, 2002; Lipscomb & Love, 1992;
Warchol , 1998). The health care sector leads all other industries in nonfatal
work place assaults.
In 2000, 48% of all nonfatal injuries resulting in days
away from work from violent acts and assaults occurred in the health and social
service sector (BLS, 20011. The incidence rate for violent acts and assaults
resulting in days away from work was 9.3 per 10,000 full-time workers for
health services workers compared to an overall private sector injury rate of 2
per 10,000 full-time workers (BLS).
Among victimizations reported in the NCVS,
mental health professionals had an incidence rate of 79.5 per 1,000 workers
compared with an overall rate of 14.8 per 1,000 workers.Nurses had an incidence
rate of 24.8 per 1,000 workers, the highest rate in the “medical” category (War
chol ) .
Violence in mental health has an extensive history, with the first
documented case of a patient fatally assaulting a psychiatrist in 1849
(Bernstein, 1981).Until the 1990s, most studies that examined the risk of
violence to psychiatrists and other therapists focused on the victim’s role,
the assaultive patient’s characteristics, and contextual factors surrounding
the assault .
Only recently have environmental risk factors been a focus of
research and nurses and aids the subjects of study.
Incidence Reporting of Assault
Bensley and colleagues (1997) compared the number of workers
compensation claims from a Washington State psychiatric hospital, formal
incident reports, and the number of incidents of assault reported on a survey
measuring attitudes and experiences related to assaults.
She found that 73% of
staff surveyed reported at least a minor injury related to a patient assault in
the past year. Only 43% of those reporting moderate, severe, or disabling
injuries related to assault filed a workers compensation claim.
The survey
found an assault incidence rate of 437 per 100 employees per year, a rate that
underestimated incident reports of assaults by a factor of more than five (
Bensley et al.).
Factors Associated With Assault
Environmental and organizational factors have been associated with
patient assaults, including understaffing (especially during times of increased
activity such as meal times), workplace security, time of day, unrestricted
access to movement and transporting patients (NIOSH, 2002).
SS Lee, Gerberich ,
Waller, Anderson, and McGovern (1999) found that among 105 nurses who had filed
a workers compensation claim for work related assault injuries, the presence of
security personnel reduced the rate of assault while the perception that
administrators considered assault to be part of the job, having received
assault prevention training, a high patient/personnel ratio, working primarily
with mental health patients, and working with patients who had a long hospital
stay increased the risk of assault.
The one characteristic patient that has been singled out as a
strong risk factor for violence is a history of violent behavior. A number of
studies have documented that a small number of patients are responsible for the
majority of assaults ( Hillbrand , Foster, & Spitz, 1996).
Drummond, Sparr
, and Gordon (1989) examined an intervention designed to identify patients with
a history of violence and found that flagging charts of patients with histories
of assaultive or disruptive behavior reduced assaults against staff by 91%.
Assault in Psychiatric Setting
Many psychiatric settings now require that all patient care
providers receive annual training in the management of aggressive patients.
However, few studies have examined the effectiveness of such training.
Those
that have generally found improvement in nurses’ knowledge, confidence, and
safety after taking an aggressive behavior management program ( Hurlebaus &
Link, 1997), Carmel and Hunter (1990) examined the relationship between
participation in training and aggressive behavior by inpatients on 27 inpatient
wards in a California State hospital and found that wards with higher staff attendance
at the training experienced lower rates of injury.
Lehman et al. (1983) found
significantly higher knowledge and confidence in trained staff.
How Prevent Violation
Runyan, Zakocs , and Zwerling (2000) reviewed 137 papers mentioning
violence prevention intervention and found that only ten of the papers
reflected databased intervention.
All interventions took place in health care,
five studies evaluated violence prevention training interventions (including
Lehmann and colleagues, and Carmel & Hunter), three examined post incident
psychological debriefing programs, and two evaluated administrative controls to
prevent violence. All were quasi experimental, without a formal control group
and with equivocal findings.
The health care workplace must be made safe for all health care
workers through the use of currently available engineering and administrative
controls, such as security alarm. systems, and adequate staffing and training.
The Occupational Safety and Health Administration published “Guidelines for
Preventing Workplace Violence for Healthcare and Social Service Workers.”
These
guidelines describe the key elements of any proactive health and safety program
including: management commitment and employee involvement, a written violence
prevention program, a worksite analysis, hazard prevention and control, medical
management and post incident response, training and education, and record
keeping and evaluation of the program.
These authors are currently evaluating
the effectiveness of these guidelines in preventing violence within the mental
health and social service work settings. Preliminary findings from the
inpatient mental health workplace indicate that a comprehensive violence
prevention program is associated with a reduction in risk factors for violence
and workplace threats and assaults (Lipscomb, in preparation).
Outcomes of Interventions
Research evaluating intervention directly at the primary,
secondary, and tertiary prevention of violence across health care settings is
critically needed to reduce workplace violence and ultimately improve patient
care. A secure and healthy work environment is essential to a positive
environment of care.
