- BackgroundA key barrier to preventing workplace violence injury is the lack of methodology for prioritizing the allocation of limited prevention resources. The hazard risk matrix was used to categorize the probability and severity of violence in hospitals to enable prioritization of units for safety intervention. MethodsProbability of violence was based on violence incidence rates; severity was based on lost time management claims for violence-related injuries. Cells of the hazard risk matrix were populated with hospital units categorized as low, medium, or high probability and severity. Hospital stakeholders reviewed the matrix after categorization to address the possible confounding of underreporting. ResultsForty-one hospital units were categorized as medium or high on both severity and probability and were prioritized for forthcoming interventions. Probability and severity were highest in psychiatric care units. ConclusionsThis risk analysis tool may be useful for hospital administrators in prioritizing units for violence injury prevention efforts.

- Background A unique and comprehensive reporting and population-based violence surveillance system in a multi-site hospital system is presented. Methods Incidence rates and rate ratios (RR) were calculated by year, hospital, violence type, and job category in six hospitals, 2003-2008. Results Incidence rates per hospital for the 6-year period ranged from a low of 1.52 to a high of 10.89 incidents/100 full-time equivalents (FTEs), with the highest risk at a hospital with an outpatient mental health facility (RR = 7.16, 95% CI = 5.17-10.26). Rates for worker-on-worker violence exceeded rates for patient-to-worker violence from 2004 to 2008. Mental health technicians (RR = 13.82, 95% CI = 11.13-17.29) and security personnel (RR = 2.25, CI = 1.68-3.00) were at greatest risk for violence. Conclusions This surveillance system provides ongoing information on professional groups and hospital departments at risk and trends in violence reporting over time. It can be used to determine where appropriate violence prevention efforts are most needed, and to evaluate violence interventions.

- Objective To investigate whether patient involvement during hospitalization for acute myocardial infarction (MI) was associated with health and behavioural outcomes 6–10 weeks after hospital discharge. Background Patient involvement has been associated with improved health outcomes in chronic disease, but less research has focused on the effects of patient involvement in acute conditions, such as MI. Design Self-administered questionnaire study. Questionnaire results were run against medical outcome data in a national database of cardiac patients. Setting and participants Cardiac patients (n = 591) on their first follow-up visit after hospitalization for MI at 11 Swedish hospitals. Main outcome measures Patient ratings of three questionnaire scales related to involvement; cardiovascular symptoms, medication compliance, participation in cardiac rehabilitation, and achievement of secondary preventive goals. Results More positive patient ratings of involvement were significantly associated with fewer cardiovascular symptoms 6–10 weeks after hospital discharge. In contrast, patients who attended cardiac rehabilitation and achieved the goals for smoking cessation and systolic blood pressure were significantly less satisfied with their involvement. No association was found between involvement ratings and medication compliance. Conclusion This study represents a first attempt to examine associations between patient involvement in the acute phase of illness and short-term health outcomes. Some significant associations between involvement and health and behavioural outcomes after acute MI were found. However, higher involvement ratings were not consistently associated with more desirable outcomes, and involvement during hospitalization was not associated with MI patient health and behaviour 6–10 weeks after hospital discharge to the extent hypothesized.

- This study examined differences between self-report and actual documentation of workplace violence (WPV) incidents in a cohort of health care workers. The study was conducted in an American hospital system with a central electronic database for reporting WPV events. In 2013, employees (n = 2010) were surveyed by mail about their experience of WPV in the previous year. Survey responses were compared with actual events entered into the electronic system. Of questionnaire respondents who self-reported a violent event in the past year, 88% had not documented an incident in the electronic system. However, more than 45% had reported violence informally, for example, to their supervisors. The researchers found that if employees were injured or lost time from work, they were more likely to formally report a violent event. Understanding the magnitude of underreporting and characteristics of health care workers who are less likely to report may assist hospitals in determining where to focus violence education and prevention efforts.

- Aim. To explore catalysts to, and circumstances surrounding, patient-to-worker violent incidents recorded by employees in a hospital system database. Background. Violence by patients towards healthcare workers (Type II workplace violence) is a significant occupational hazard in hospitals worldwide. Studies to date have failed to investigate its root causes due to a lack of empirical research based on documented episodes of patient violence. Design. Qualitative content analysis. Methods. Content analysis was conducted on the total sample of 214 Type II incidents documented in 2011 by employees of an American hospital system with a centralized reporting system. Findings. The majority of incidents were reported by nurses (39.8%),security staff (15.9%) and nurse assistants (14.4%). Three distinct themes were identified from the analysis: Patient Behaviour, Patient Care and Situational Events. Specific causes of violence related to Patient Behaviour were cognitive impairment and demanding to leave. Catalysts related to patient care were the use of needles, patient pain/discomfort and physical transfers of patients. Situational factors included the use/presence of restraints; transitions in the care process; intervening to protect patients and/or staff; and redirecting patients. Conclusions. Identifying catalysts and situations involved in patient violence in hospitals informs administrators about potential targets for intervention. Hospital staff can be trained to recognize these specific risk factors for patient violence and can be educated in how to best mitigate or prevent the most common forms of violent behaviour. A social-ecological model can be adapted to the hospital setting as a framework for prevention of patient violence towards staff.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Documented incidents of violence provide the foundation for any workplace violence prevention program. However, no published research to date has examined stakeholders' preferences for workplace violence data reports in healthcare settings. If relevant data are not readily available and effectively summarized and presented, the likelihood is low that they will be utilized by stakeholders in targeted efforts to reduce violence. OBJECTIVE: To discover and describe hospital system stakeholders' perceptions of database-generated workplace violence data reports. PARTICIPANTS: Eight hospital system stakeholders representing Human Resources, Security, Occupational Health Services, Quality and Safety, and Labor in a large, metropolitan hospital system. METHODS: The hospital system utilizes a central database for reporting adverse workplace events, including incidents of violence. A focus group was conducted to identify stakeholders' preferences and specifications for standardized, computerized reports of workplace violence data to be generated by the central database. The discussion was audio-taped, transcribed verbatim, processed as text, and analyzed using stepwise content analysis. RESULTS: Five distinct themes emerged from participant responses: Concerns, Etiology, Customization, Use, and Outcomes. In general, stakeholders wanted data reports to provide "the big picture," i.e., rates of occurrence; reasons for and details regarding incident occurrence; consequences for the individual employee and/or the workplace; and organizational efforts that were employed to deal with the incident. CONCLUSIONS: Exploring stakeholder views regarding workplace violence summary reports provided concrete information on the preferred content, format, and use of workplace violence data. Participants desired both epidemiological and incident-specific data in order to better understand and work to prevent the workplace violence occurring in their hospital system.

- Violence toward hospital workers is an internationally recognized occupational hazard. While patients are frequently perpetrators of physical violence, other employees are often responsible for acts of nonphysical violence. However, few hospitals have systems for documenting and monitoring worker-on-worker violence. This study encompassed all incidents of worker-on-worker violence recorded by employees in a hospital system database over a six-year period. Incidence rates per 100 full-time equivalents (FTEs) and rate ratios (RR) were calculated by year, hospital, and job category. The majority (87%) of worker-on-worker incidents involved nonphysical conflict. The overall incidence rate was 1.65/100 FTEs, ranging among the six hospitals from 0.54 to 3.42/100 FTEs. Based on multivariate analysis, no single professional group was at increased risk for worker-on-worker violence. Co-worker violence threatens the well-being of hospital employees and should be regularly tracked with other forms of work-place violence so that suitable intervention programs can be implemented and assessed.

- Aims and objectivesTo identify common catalysts of worker-to-worker violence and incivility in hospital settings. BackgroundWorker-to-worker violence and incivility are prevalent forms of mistreatment in healthcare workplaces. These are forms of counterproductive work behaviour that can lead to negative outcomes for employees, patients and the organisation overall. Identifying the factors that lead to co-worker mistreatment is a critical first step in the development of interventions targeting these behaviours. DesignRetrospective descriptive study. MethodsQualitative content analysis was conducted on the total sample (n=141) of employee incident reports of worker-to-worker violence and incivility that were documented in 2011 at a large American hospital system. ResultsMore than 50% of the incidents involved nurses, and the majority of incidents did not involve physical violence. Two primary themes emerged from the analysis: Work Behaviour and Work Organisation. Incidents in the Work Behaviour category were often sparked by unprofessional behaviour, disagreement over responsibilities for work tasks or methods of patient care, and dissatisfaction with a co-worker's performance. Incidents in the Work Organisation category involved conflicts or aggression arising from failure to following protocol, patient assignments, limited resources and high workload. ConclusionIncidents of worker-to-worker violence and incivility stemmed from dissatisfaction with employee behaviour or from organisational practices or work constraints. These incident descriptions reflect worker dissatisfaction and frustration, resulting from poor communication and collaboration between employees, all of which threaten work productivity. Relevance to clinical practiceViolence and incivility between hospital employees can contribute to turnover of top performers, hinder effective teamwork and jeopardise the quality of patient care. Identification of common catalysts for worker-to-worker violence and incivility informs the development of mistreatment prevention programmes that can be used to educate hospital staff.

- Worker-to-worker (Type III) violence is prevalent in health care settings and has potential adverse consequences for employees and organizations. Little research has examined perpetrator characteristics of this type of violence. The current study is a descriptive examination of the common demographic and work-related characteristics of perpetrators of Type III workplace violence among hospital workers. Analysis was based on documented incidents of Type III violence reported within a large hospital system from 2010 to 2012. Nurses were involved as either the perpetrator or target in the five most common perpetrator-target dyads. Incidence rate ratios revealed that patient care associates and nurses were significantly more likely to be perpetrators than other job titles. By examining characteristics of perpetrators and common worker dyads involved in Type III workplace violence, hospital stakeholders and unit supervisors have a starting point to develop strategies for reducing conflict between workers.

- The optical properties of isotope-pure (SiC)-Si-28-C-12, natural SiC and enriched with C-13 isotope samples of the 4H polytype are studied by means of Raman and photoluminescence spectroscopies. The phonon energies of the Raman active phonons at the Gamma point and the phonons at the M point of the Brillouin zone are experimentally determined. The excitonic bandgaps of the samples are accurately derived using tunable laser excitation and the phonon energies obtained from the photoluminescence spectra. Qualitative comparison with previously reported results on isotope-controlled Si is presented.

- The objective of this study was to determine whether perceived health status of Iraqi immigrants and refugees residing in the United States was related to pre-migration environmental stress, current unemployment, and if they had emigrated before or after the 1991 Gulf War. A random sample of Iraqis residing in Southeast Michigan, US, was interviewed using an Arab language structured survey. The main outcome measure was self-rated health (SRH). Major predictors included socioeconomics, employment status, pre-migration environmental stress, and health disorders. Path analysis was used to look at mediating effects between predictors and SRH. We found that SRH was significantly worse among participants that had left Iraq after the 1991 Gulf War. Unemployment and environmental stress exposure were inversely related to SRH. There was a direct path between Gulf War exposure and poor health. In addition, there were indirect paths mediated through psychosomatic and psychiatric disorders to SRH. Another path went from Gulf War exposure, via environmental stress and somatic health to poor health. Unemployment had a direct path, as well as indirect paths mediated through psychiatric and psychosomatic disorders, to poor self-rated health. In conclusion, these results suggest that pre- as well as post-migration factors, and period of migration, affect health.

- Renewable fuel generation is essential for a low carbon footprint economy. Thus, over the last five decades, a significant effort has been dedicated towards increasing the performance of solar fuels generating devices. Specifically, the solar to hydrogen efficiency of photoelectrochemical cells has progressed steadily towards its fundamental limit, and the faradaic efficiency towards valuable products in CO2 reduction systems has increased dramatically. However, there are still numerous scientific and engineering challenges that must be overcame in order to turn solar fuels into a viable technology. At the electrode and device level, the conversion efficiency, stability and products selectivity must be increased significantly. Meanwhile, these performance metrics must be maintained when scaling up devices and systems while maintaining an acceptable cost and carbon footprint. This roadmap surveys different aspects of this endeavor: system benchmarking, device scaling, various approaches for photoelectrodes design, materials discovery, and catalysis. Each of the sections in the roadmap focuses on a single topic, discussing the state of the art, the key challenges and advancements required to meet them. The roadmap can be used as a guide for researchers and funding agencies highlighting the most pressing needs of the field.
