The Violence Prevention Community Meeting: a multi-site study
Lanza M , Ridenour M , Hendricks S , Rierdan J , Zeiss R , Schmidt S , Lovelace J , Amandus H . Arch Psychiatr Nurs 2016 30 (3) 382-6 OBJECTIVE: The Violence Prevention Community Meeting (VPCM) is a specialized form of community meeting in which avoiding violence and promoting non-violent problem solving and interpersonal civility are focal points. A nationwide study to assess the VPCM as an effective intervention to reduce workplace violence was undertaken. PARTICIPANTS: Seven acute locked psychiatric units of the Veterans Health Administration (VHA) throughout the United States participated in the study. METHODS: All patients and all staff on the seven in-patient locked psychiatry units participated in the intervention (VPCM) or as a control (treatment as usual). The study was 21weeks at each site. The three time periods were pre-treatment weeks 1-3, treatment weeks 4-18, and post-treatment weeks 19-21. The VPCM was conducted during the treatment weeks. RESULTS: Overall rates of aggression declined by 0.6% (95% CI: -5.6%, 6.5%; nonsignificant) per week in the intervention hospitals and by 5.1% (95% CI: 0.4%, 9.6%; significant) per week for the control hospitals. CONCLUSIONS: Aggression decreased for both the intervention and control hospitals which could be due to enrollment in a research study and thus being more aware of their ability to address workplace violence at their site. |
Compliance to two city convenience store ordinance requirements
Chaumont Menendez CK , Amandus HE , Wu N , Hendricks SA . Inj Prev 2015 22 (2) 117-22 BACKGROUND: Robbery-related homicides and assaults are the leading cause of death in retail businesses. Robbery reduction approaches focus on compliance to Crime Prevention Through Environmental Design (CPTED) guidelines. PURPOSE: We evaluated the level of compliance to CPTED guidelines specified by convenience store safety ordinances effective in 2010 in Dallas and Houston, Texas, USA. METHODS: Convenience stores were defined as businesses less than 10 000 square feet that sell grocery items. Store managers were interviewed for store ordinance requirements from August to November 2011, in a random sample of 594 (289 in Dallas, 305 in Houston) convenience stores that were open before and after the effective dates of their city's ordinance. Data were collected in 2011 and analysed in 2012-2014. RESULTS: Overall, 9% of stores were in full compliance, although 79% reported being registered with the police departments as compliant. Compliance was consistently significantly higher in Dallas than in Houston for many requirements and by store type. Compliance was lower among single owner-operator stores compared with corporate/franchise stores. Compliance to individual requirements was lowest for signage and visibility. CONCLUSIONS: Full compliance to the required safety measures is consistent with industry 'best practices' and evidence-based workplace violence prevention research findings. In Houston and Dallas compliance was higher for some CPTED requirements but not the less costly approaches that are also the more straightforward to adopt. |
Minimum requirements for taxicab security cameras
Zeng S , Amandus HE , Amendola AA , Newbraugh BH , Cantis DM , Weaver D . J Transp Technol 2014 4 (3) 216-255 PROBLEM: The homicide rate of taxicab-industry is 20 times greater than that of all workers. A NIOSH study showed that cities with taxicab-security cameras experienced significant reduction in taxicab driver homicides. METHODS: Minimum technical requirements and a standard test protocol for taxicab-security cameras for effective taxicab-facial identification were determined. The study took more than 10,000 photographs of human-face charts in a simulated-taxicab with various photographic resolutions, dynamic ranges, lens-distortions, and motion-blurs in various light and cab-seat conditions. Thirteen volunteer photograph-evaluators evaluated these face photographs and voted for the minimum technical requirements for taxicab-security cameras. RESULTS: Five worst-case scenario photographic image quality thresholds were suggested: the resolution of XGA-format, highlight-dynamic-range of 1 EV, twilight-dynamic-range of 3.3 EV, lens-distortion of 30%, and shutter-speed of 1/30 second. PRACTICAL APPLICATIONS: These minimum requirements will help taxicab regulators and fleets to identify effective taxicab-security cameras, and help taxicabsecurity camera manufacturers to improve the camera facial identification capability. |
Incidence and risk factors of workplace violence on psychiatric staff
Ridenour M , Lanza M , Hendricks S , Hartley D , Rierdan J , Zeiss R , Amandus H . Work 2014 51 (1) 19-28 BACKGROUND: A study by Hesketh et al. found that 20% of psychiatric nurses were physically assaulted, 43% were threatened with physical assault, and 55% were verbally assaulted at least once during the equivalent of a single work week. From 2005 through 2009, the U.S. Department of Justice reported that mental health occupations had the second highest average annual rate of workplace violence, 21 violent crimes per 1,000 employed persons aged 16 or older. OBJECTIVE: An evaluation of risk factors associated with patient aggression towards nursing staff at eight locked psychiatric units. PARTICIPANTS: Two-hundred eighty-four nurses in eight acute locked psychiatric units of the Veterans Health Administration throughout the United States between September 2007 and September 2010. METHODS: Rates were calculated by dividing the number of incidents by the total number of hours worked by all nurses, then multiplying by 40 (units of incidents per nurse per 40-hour work week). Risk factors associated with these rates were analyzed using generalized estimating equations with a Poisson model. RESULTS: Combining the data across all hospitals and weeks, the overall rate was 0.60 for verbal aggression incidents and 0.19 for physical aggression, per nurse per week. For physical incidents, the evening shift (3 pm - 11 pm) demonstrated a significantly higher rate of aggression than the day shift (7 am - 3 pm). Weeks that had a case-mix with a higher percentage of patients with personality disorders were significantly associated with a higher risk of verbal and physical aggression. CONCLUSION: Healthcare workers in psychiatric settings are at high risk for aggression from patients. |
Cities with camera-equipped taxicabs experience reduced taxicab driver homicide rates: United States, 1996-2010
Chaumont Menendez C , Amandus H , Damadi P , Wu N , Konda S , Hendricks S . Crime Sci 2014 3 (1) 4 BACKGROUND: Driving a taxicab remains one of the most dangerous occupations in the United States, with leading homicide rates. Although safety equipment designed to reduce robberies exists, it is not clear what effect it has on reducing taxicab driver homicides. FINDINGS: Taxicab driver homicide crime reports for 1996 through 2010 were collected from 20 of the largest cities (>200,000) in the United States: 7 cities with cameras installed in cabs, 6 cities with partitions installed, and 7 cities with neither cameras nor partitions. Poisson regression modeling using generalized estimating equations provided city taxicab driver homicide rates while accounting for serial correlation and clustering of data within cities. Two separate models were constructed to compare (1) cities with cameras installed in taxicabs versus cities with neither cameras nor partitions and (2) cities with partitions installed in taxicabs versus cities with neither cameras nor partitions. Cities with cameras installed in cabs experienced a significant reduction in homicides after cameras were installed (adjRR=0.11, CL 0.06-0.24) and compared to cities with neither cameras nor partitions (adjRR=0.32, CL 0.15-0.67). Cities with partitions installed in taxicabs experienced a reduction in homicides (adjRR=0.78, CL 0.41-1.47) compared to cities with neither cameras nor partitions, but it was not statistically significant. CONCLUSIONS: The findings suggest cameras installed in taxicabs are highly effective in reducing homicides among taxicab drivers. Although not statistically significant, the findings suggest partitions installed in taxicabs may be effective. |
Occupational fatalities among driver/sales workers and truck drivers in the United States, 2003-2008
Chen GX , Amandus HE , Wu N . Am J Ind Med 2014 57 (7) 800-9 BACKGROUND: This study provides a national profile of occupational fatalities among truck drivers and driver-sales workers. METHODS: Data from the 2003-2008 Census of Fatal Occupational Injuries were used. Cases were extracted specifically for occupational subcategories included in the Driver/Sales Workers and Truck Drivers occupational category: Driver/Sales Workers, Heavy and Tractor-Trailer Truck Drivers, and Light Truck or Delivery Services Drivers. RESULTS: In 2003-2008, the group Driver/Sales Workers and Truck Drivers had 5,568 occupational fatalities, representing 17% of all occupational fatalities in the United States. The majority of these fatalities were in the subgroup Heavy and Tractor-Trailer Truck Drivers (85%) and due to transportation incidents (80%). Older and male drivers had higher fatality rates than their counterparts. CONCLUSIONS: Findings suggest a need for targeted interventions to reduce highway fatalities among heavy truck drivers. Better employment data are needed to separate the three occupational subcategories by worker characteristic and employment history for use in research and prevention efforts. |
Effectiveness of taxicab security equipment in reducing driver homicide rates
Menendez CK , Amandus HE , Damadi P , Wu N , Konda S , Hendricks SA . Am J Prev Med 2013 45 (1) 1-8 BACKGROUND: Taxicab drivers historically have had one of the highest work-related homicide rates of any occupation. In 2010 the taxicab driver homicide rate was 7.4 per 100,000 drivers, compared to the overall rate of 0.37 per 100,000 workers. PURPOSE: Evaluate the effectiveness of taxicab security cameras and partitions on citywide taxicab driver homicide rates. METHODS: Taxicab driver homicide rates were compared in 26 major cities in the U.S. licensing taxicabs with security cameras (n=8); bullet-resistant partitions (n=7); and cities where taxicabs were not equipped with either security cameras or partitions (n=11). News clippings of taxicab driver homicides and the number of licensed taxicabs by city were used to construct taxicab driver homicide rates spanning 15 years (1996-2010). Generalized estimating equations were constructed to model the Poisson-distributed homicide rates on city-specific safety equipment installation status, controlling for city homicide rate and the concurrent decline of homicide rates over time. Data were analyzed in 2012. RESULTS: Cities with cameras experienced a threefold reduction in taxicab driver homicides compared with control cities (RR=0.27; 95% CI=0.12, 0.61; p=0.002). There was no difference in homicide rates for cities with partitions compared with control cities (RR=1.15; 95% CI=0.80, 1.64; p=0.575). CONCLUSIONS: Municipal ordinances and company policies mandating security cameras appear to be highly effective in reducing taxicab driver deaths due to workplace violence. |
Disparities in work-related homicide rates in selected retail industries in the United States, 2003-2008
Menendez CC , Konda S , Hendricks S , Amandus H . J Safety Res 2012 44 25-9 PROBLEM: Segments within the retail industry have a substantially higher rate of work-related fatality due to workplace violence compared to the retail industry overall. Certain demographic subgroups may be at higher risk. METHOD: National traumatic injury surveillance data were analyzed to characterize the distribution of fatality rates due to workplace violence among selected retail workers in the United States from 2003 through 2008. RESULTS: Overall, the highest fatality rates due to work-related homicide occurred among men, workers aged ≥ 65 years, black, Asian, foreign-born and Southern workers. Among foreign-born workers, those aged 16-24 years, non-Hispanic whites and Asians experienced substantially higher fatality rates compared to their native-born counterparts. CONCLUSIONS: The burden of work-related homicide in the retail industry falls more heavily on several demographic groups, including racial minorities and the foreign-born. Further research should examine the causes of these trends. Interventions designed to prevent workplace violence should target these groups. |
Workplace violence among Pennsylvania education workers: differences among occupations
Tiesman H , Konda S , Hendricks S , Mercer D , Amandus H . J Safety Res 2012 44 65-71 PROBLEM: The literature on education employees as victims of workplace violence (WPV) is limited. Moreover, prior studies have focused primarily on teachers. The purpose of this study was to measure the prevalence and characteristics of physical and non-physical WPV in a state-based cohort of education workers. METHOD: A state-wide sample of 6,450 workers was drawn using de-identified union membership lists provided by Pennsylvania's education unions. The sample was stratified on gender, occupation, and school location. Occupational groups included special education teachers, general education teachers, pupil service professionals, education support personnel, and teaching aides. A cross-sectional survey was mailed to participants. Analyses were performed using Proc SURVEY methods in SAS. RESULTS: An estimated 7.8% (95%CI = 6.6 − 9.1) of education workers were physically assaulted and 28.9% (95%CI = 26.4 − 31.5) experienced a non-physical WPV event during the 2009–2010 school year. Special education teachers were significantly more likely to be physically assaulted and experience a non-physical WPV event compared to general education teachers (Prevalence Rate Ratio = 3.6, 95% 2.4-5.5; PRR = 1.4, 95%CI = 1.1 − 1.8). The majority of education workers were physically assaulted during regular school hours (97%) by a student (95%). Education support personnel experienced a large percentage of physical assaults perpetrated by co-workers (36%). The most common perpetrator of non-physical WPV was a student (73%); however, 15% of non-physical events were perpetrated by co-workers. DISCUSSION: Special education teachers were at the highest risk for both physical and non-physical WPV. Education support personnel experienced a high percentage of WPV perpetrated by co-workers. If not already present, schools should consider implementing comprehensive WPV prevention programs for their employees. IMPACT ON INDUSTRY: Those employed in a school setting are at risk for physical and non-physical WPV. Special education teachers have unique workplace hazards. Strategies that protect the special education teacher, while still protecting the special education student should be considered. |
The epidemiology of slips, trips, and falls in a helicopter manufacturing plant
Amandus H , Bell J , Tiesman H , Biddle E . Hum Factors 2012 54 (3) 387-395 OBJECTIVE: The purpose of this evaluation was to evaluate the causes and costs of slips, trips, and falls (STFs) in a helicopter manufacturing plant. BACKGROUND: STFs are a significant portion of the total industry injury burden. METHODS: For this study, 4,070 helicopter plant workers who were employed from January 1, 2004, through February 28, 2008, were enrolled. Company records on workers' compensation claims, occupational health first report of injury, and payroll records on hours worked were collected. Cause and source of all injuries, including STFs, were coded for analysis. RESULTS: During the 4-year study period, there were 2,378 injuries and 226 STFs (46 falls [20%] to a lower level, 117 [52%] falls on the same level, 41 [18%] from loss of balance without a fall, and 22 [10%] from other events). Of the 226 STFs, 123 falls to the same level were caused by slippery substances (52), objects on floor (43), and surface hazards (28), and they cost $1,543,946. Falls to lower levels primarily involved access to stands to and from aircraft and falling off large machines. CONCLUSION: More than half of the STF injury claims likely could have been prevented by housekeeping and maintenance, and this cost saving could reasonably offset a considerable portion of the cost of prevention. Training and stand modifications could be considered to prevent falls from elevation from stands, machines, and aircraft. APPLICATION: Recommendations for STF prevention are discussed. |
Workplace homicides among U.S. women: the role of intimate partner violence
Tiesman HM , Gurka KK , Konda S , Coben JH , Amandus HE . Ann Epidemiol 2012 22 (4) 277-84 PURPOSE: Intimate partner violence (IPV) is an important public health issue with serious consequences for the workplace. Workplace homicides occurring to U.S. women over a 6-year period, including those perpetrated by an intimate partner, are described. METHODS: Workplace homicides among U.S. women from 2003 to 2008 were categorized into type I (criminal intent), type II (customer/client), type III (co-worker), or type IV (personal relations) events using the Census of Fatal Occupational Injuries. Fatality rates were calculated and compared among workplace violence (WPV) types, occupations, and characteristics including location of homicide, type of workplace, time of day, and weapon used. RESULTS: Between 2003 and 2008, 648 women were feloniously killed on the job. The leading cause of workplace homicide for U.S. women was criminal intent, such as robbing a store (n = 212; 39%), followed by homicides perpetrated by a personal relation (n = 181; 33%). The majority of these personal relations were intimate partners (n = 142; 78%). Over half of workplace homicides perpetrated by intimate partners occurred in parking lots and public buildings (n = 91; 51%). CONCLUSIONS: A large percentage of homicides occurring to women at work are perpetrated by intimate partners. WPV prevention programs should incorporate strategies to prevent and respond to IPV. |
Eleven years of occupational mortality in law enforcement: the census of fatal occupational injuries, 1992-2002
Tiesman HM , Hendricks SA , Bell JL , Amandus HA . Am J Ind Med 2010 53 (9) 940-9 BACKGROUND: Occupational injury deaths remain high for Law Enforcement Officers (LEOs). This study describes and compares intentional and transportation-related fatality rates in US LEOs between 1992 and 2002. METHODS: Workplace injury deaths among LEOs from 1992 to 2002 were categorized into "Intentional," "Transportation-related," and "Other," using the Census of Fatal Occupational Injuries. Occupations included in this analysis were sheriffs and bailiffs, police and detectives, non-public service guards, and correctional officers. Fatality rates were compared among law enforcement occupations, cause of death, and demographics with rate ratios and 95% confidence intervals. RESULTS: During the 11-year period, 2,280 workers died from an occupational injury, for a fatality rate of 11.8 per 100,000 across all LEO occupations. Forty-seven percent were homicides (n = 1,072, rate 5.6 per 100,000), 36% transportation-related (n = 815, rate 4.2 per 100,000), 11% were due to other causes (n = 249, rate 1.3 per 100,000), and 5% were workplace suicides (n = 122, rate 0.6 per 100,000). The proportion of fatalities by cause of death differed significantly between occupations (P < 0.0001). Sheriffs and bailiffs experience a high risk for occupational injury death compared to other law enforcement occupations. Of the transportation-related fatalities, LEOs were operating a motor-vehicle in 58% of the incidents and 22% of the fatalities were struck by incidents. CONCLUSIONS: Transportation-related deaths were nearly as common as homicides as a cause of occupational injury death among US LEOs. Struck by vehicle incidents remain an important and overlooked cause of death. This research points to opportunities for the prevention of transportation-related deaths in law enforcement. Am. J.

Robbery and violence prevention in small retail businesses
Chronister T , Oxnard PD , Casteel C , Peek Asa C , Amandus H , Hartley D . Police Chief 2009 LXXVI (10) 1-5 Police departments work with small businesses to seek methodologies to thwart crimes. In Oxnard, California, it was found that the most effective strategies to mitigate robberies and the resulting violence might be surprising because they are low in cost; easy to implement and sustain; do not require any special technological know-how to use; and, for the most part, are also good for the business. After arriving at this conclusion, the Oxnard Police Department joined forces with the occupational safety research community to find the answers. |
