To identify whether university students who have both food-safety knowledge and beliefs perform risk-reduction behaviors. Cross-sectional research using a questionnaire that included food-safety knowledge, perceptions, risk-reduction behavior, stages for the selection of safer food based on the Transtheoretical Model, and demographic characteristics. Four universities in eastern Japan and 2 universities in western Japan. University students (n = 799). Food-safety knowledge, beliefs, and risk-reduction behaviors. Answers on measures assessing risk perception and food-safety knowledge were combined to form 4 groups of participants. Relationships among demographic characteristics, the 4 groups, risk-reduction behaviors, stage of change, and severity and susceptibility were assessed. The proportion of students who had more knowledge of food safety and a belief that "there are no 100% safe food items" was high in the group that frequently performed risk-reduction behaviors, as it was in the group who had taken a basic class about food or health care and who had, or were working toward, a food or nutrition qualification. University students who thought that there were no 100% safe food items and who had more knowledge about food safety were more likely to confirm food-safety information when selecting food.

Abstract Objective To explore what individuals at risk of injury from using paraffin (also known as kerosene) know about paraffin safety, what they do to protect themselves and their families from paraffin-related injury, and how they perceive their risk for such injury. Also, to explore interrelations between these factors and age, sex, education and income. Methods A sample of 238 individuals was randomly recruited from low-income housing districts near Cape Town, South Africa in 2007. Trained research assistants interviewed participants to explore their knowledge about paraffin-related safety and their perceived risk of injury from using paraffin. Researchers inspected participants’ homes to evaluate paraffin safety practices. Descriptive and correlational analyses were conducted. Findings Participants had relatively low levels of knowledge about paraffin-related safety. They had high levels of unsafe practice and their perceived risk of injury was moderate. Knowledge of paraffin safety and safe practices were positively correlated with each other. Greater knowledge showed a negative correlation with the perception of being at risk for injury, but safe practices showed no correlation with perceived risk of injury. Formal education, the number of children in the home and frequency of paraffin use were positively correlated with knowledge but not with safe practices. The only significant correlate to safe practices was greater income, perhaps a reflection of the impact of financial resources on paraffin safety practices. Conclusion To develop successful paraffin safety interventions, it is necessary to understand baseline levels of knowledge, practice and perceived risk of injury among at-risk populations. Our findings could be of value for designing interventions that will increase knowledge, improve safe practices and lead to the accurate perception of the risk of injury from using paraffin.

This study describes road traffic injuries among school-aged children in Guangzhou, China, and examines the effect of road safety knowledge and risk behaviours on road traffic injuries. A stratified cluster sample of 3747 children from six primary schools and six middle schools in Guangzhou, China, was surveyed. Data were collected on sociodemographic factors and road traffic injuries during the past year. Knowledge about road safety rules was assessed using a 14-item road safety knowledge index, and risky road safety behaviours were measured using a 25-item road safety behaviour index. A total of 403 (10.8%) students reported having at least one road traffic injury during the past 12 months. A high proportion of injuries was found among children who were boys, in primary school and from the suburbs. Bicycle-related injuries were the most common (46.0% of all injuries). Motor vehicle-related injuries had higher hospitalisation rates and worse psychological impact than bicycle or pedestrian injuries. Children with low and medium road safety knowledge had 1.5 to 3 times the odds of injury compared with students with high road safety knowledge. Students with high scores on the risky road behaviour index had twice the odds of injury (OR 2.04, 95% CI 1.47 to 2.84) compared with students with low scores. Better road safety knowledge and the avoidance of walking or cycling-related risk behaviours are protective factors for road traffic injuries among Chinese school children. More injury prevention programmes are needed to improve road safety knowledge and reduce risk behaviours.
Food safety knowledge and practices of young adults.
Green, Eric J; Knechtges, Paul L
2015-06-01
The objective of the study described in this article was to ascertain the food safety knowledge and practices of undergraduate students attending a major American university. The study participants were undergraduate college students (mean age 18.9 +/- 1.14 SD) enrolled in a required health course. The students were invited to take a validated food safety knowledge questionnaire as part of a health risk behavior online survey. The 786 respondents indicated their food is most often prepared at on-campus dining facilities and the majority of the students (72%) felt they were "unlikely or "very unlikely" at risk of foodborne disease. The mean food safety knowledge score of the participants was 10.23 (43%) +/- 4.13 SD (25%-60%), indicating the study population overall has poor knowledge of safe food practices. As a result, food safety educational initiatives and awareness campaigns should be developed to better inform young adults about safe food handling practices and habits.

Aviation safety risk modeling has elements of both art and science. In a complex domain, such as the National Airspace System (NAS), it is essential that knowledge elicitation (KE) sessions with domain experts be performed to facilitate the making of plausible inferences about the possible impacts of future technologies and procedures. This study discusses lessons learned throughout the multiple KE sessions held with domain experts to construct probabilistic safety risk models for a Loss of Control Accident Framework (LOCAF), FLightdeck Automation Problems (FLAP), and Runway Incursion (RI) mishap scenarios. The intent of these safety risk models is to support a portfolio analysis of NASA's Aviation Safety Program (AvSP). These models use the flexible, probabilistic approach of Bayesian Belief Networks (BBNs) and influence diagrams to model the complex interactions of aviation system risk factors. Each KE session had a different set of experts with diverse expertise, such as pilot, air traffic controller, certification, and/or human factors knowledge that was elicited to construct a composite, systems-level risk model. There were numerous "lessons learned" from these KE sessions that deal with behavioral aggregation, conditional probability modeling, object-oriented construction, interpretation of the safety risk results, and model verification/validation that are presented in this paper.
Structural equation modeling of pesticide poisoning, depression, safety, and injury.
Beseler, Cheryl L; Stallones, Lorann

The role of pesticide poisoning in risk of injuries may operate through a link between pesticide-induced depressive symptoms and reduced engagement in safety behaviors. The authors conducted structural equation modeling of cross-sectional data to examine the pattern of associations between pesticide poisoning, depressive symptoms, safety knowledge, safety behaviors, and injury. Interviews of 1637 Colorado farm operators and their spouses from 964 farms were conducted during 1993-1997. Pesticide poisoning was assessed based on a history of ever having been poisoned. The Center for Epidemiologic Studies-Depression scale was used to assess depressive symptoms. Safety knowledge and safety behaviors were assessed using ten items for each latent variable. Outcomes were safety behaviors and injuries. A total of 154 injuries occurred among 1604 individuals with complete data. Pesticide poisoning, financial problems, health, and age predicted negative affect/somatic depressive symptoms with similar effect sizes; sex did not. Depression was more strongly associated with safety behavior than was safety knowledge. Two safety behaviors were significantly associated with an increased risk of injury. This study emphasizes the importance of financial problems and health on depression, and provides further evidence for the link between neurological effects of past pesticide poisoning on risk-taking behaviors and injury.

Health and safety instructions are important components of occupational prevention. Albeit instruction is mandatory in most countries, research suggests that safety knowledge varies among the workforce. We analysed a large European sample to explore if all subgroups of employees are equally reached. In a comparative perspective, we also investigated if country-level determinants influence the variance of safety knowledge between countries. We used data on 24,534 employees from 27 countries who participated in the 2010 European Working Conditions Survey. Safety knowledge was measured as self-assessed quality of safety information. Country-level determinants were added from Eurostat databases (gross domestic product) and the European Survey of Enterprises on New and Emerging Risks (ESENER) study (% companies with A: safety plan or B: a labour inspectorate visit). Associations between knowledge, sociodemographic, occupational characteristics and macrodeterminants were studied with hierarchical regression models. In our sample, 10.1% reported a low degree of health and safety knowledge. Across all countries, younger workers, lower educated workers, production workers, private sector employees, those with less job experience or a temporary contract, or those who work in small businesses were more likely to report low levels of information. Moreover, low information prevalence varied by country. Countries with a high proportion of companies with a safety plan and recent labour inspectorate on-site visits had higher proportions of informed workers. A vast majority reported to be well informed about safety risks but systematic inequalities in the degree of knowledge between subgroups were evident. Further efforts on the workplace, the organisational and the political level are needed to universally implement existing occupational safety regulations.

The emergency department has been described as a high-risk area for errors. It is also known that working conditions such as a high workload and shortage off staff in the healthcare field are common factors that negatively affect patient safety. A limited amount of research has been conducted with regard to patient safety in Swedish emergency departments. Additionally, there is a lack of knowledge about clinicians' perceptions of patient safety risks. Therefore, the purpose of this study was to describe emergency department clinicians' experiences with regard to patient safety risks. Semi-structured interviews were conducted with 10 physicians and 10 registered nurses from two emergency departments. Interviews were analysed by inductive content analysis. The experiences reflect the complexities involved in the daily operation of a professional practice, and the perception of risks due to a high workload, lack of control, communication and organizational failures. The results reflect a complex system in which high workload was perceived as a risk for patient safety and that, in a combination with other risks, was thought to further jeopardize patient safety. Emergency department staff should be involved in the development of patient safety procedures in order to increase knowledge regarding risk factors as well as identify strategies which can facilitate the maintenance of patient safety during periods in which the workload is high.

Understanding consumers' food safety practices and knowledge supports food safety education for the prevention of foodborne illness. The objective of this study was to describe Canadian consumer food safety practices and knowledge. This study identifies demographic groups for targeted food safety education messaging and establishes a baseline measurement to assess the effectiveness of food safety interventions over time. Questions regarding consumer food safety practices and knowledge were included in a population-based telephone survey, Foodbook, conducted from November 2014 to March 2015. The results were analyzed nationally by age group and by gender. The results showed that approximately 90% of Canadians reported taking the recommended cleaning and separating precautions when handling raw meat to prevent foodborne illness. Only 29% of respondents reported using a food thermometer when cooking any meat, and even fewer (12%) reported using a food thermometer for small cuts of meat such as chicken pieces. The majority (>80%) of Canadians were aware of the foodborne illness risks related to chicken and hamburger, but fewer (<40%) were aware of the risks related to frozen chicken nuggets, alfalfa sprouts, soft unpasteurized cheese, and unpasteurized juices. Generally, men were less likely to follow cooking instructions on packaging and took fewer steps to prevent cross-contamination than women. The youngest (18 to 29 years) age group was less likely to take steps to avoid cross-contamination and was less aware of the risks associated with eating an undercooked hamburger. The oldest (60+ years) respondents were less likely to be aware of the risks associated with raw eggs, alfalfa sprouts, and unpasteurized juice than the middle (30 to 59 years) age group. As a priority, food safety education in Canada should focus on increasing people's awareness of high-risk foods, specifically foods for which the awareness of risk found in this study was low; targeting messaging to demographic groups as appropriate; and promoting the use of food thermometers when cooking meat and poultry.

Objective Unintentional drowning is the most common cause of childhood death in rural China. Global intervention efforts offer mixed results regarding the efficacy of educational programs. Methods Using a randomized controlled design, we evaluated a testimonial-based intervention to reduce drowning risk among 280 3rd- and 4th-grade rural Chinese children. Children were randomly assigned to view either testimonials on drowning risk (intervention) or dog-bite risk (control). Safety knowledge and perceived vulnerability were measured by self-report questionnaires, and simulated behaviors in and near water were assessed with a culturally appropriate dollhouse task. Results Children in the intervention group had improved children’s safety knowledge and simulated behaviors but not perceived vulnerability compared with controls. Conclusions The testimonial-based intervention’s efficacy appears promising, as it improved safety knowledge and simulated risk behaviors with water among rural Chinese children. PMID:26546476

Dog-bite injuries pose significant threat to children globally. School-age children are especially at risk because of their insufficient safety knowledge and cognitively immature tendency toward low perceived vulnerability to bites, and this risk is elevated further for school-age children living in rural China due to the large number of stray dogs, all potential rabies carriers, present in their communities. This randomized controlled trial evaluated whether viewing an educational video of testimonials would change safety knowledge, perceived vulnerability, and simulated behaviors with dogs among a sample of 280 third and fourth graders living in rural China. Participants were randomly assigned to view either an educational video of testimonials on dog-bite prevention (treatment) or an educational video of testimonials on drowning prevention (comparison). Safety knowledge, perceived vulnerability to dog bites, and simulated behavior with dogs using a dollhouse model were assessed both before and after exposure to the video of testimonials. Children who watched the educational video of testimonials on dog-bite prevention had increased safety knowledge, higher perceived vulnerability, and less risky simulated behaviors with dogs compared with the comparison group. Mediation analysis revealed that the intervention successfully changed children's simulated behaviors with dogs through greater safety knowledge and increased perceived vulnerability. Results suggest the incorporation of testimonials into injury prevention programs has potential for broad global dissemination. The fact that both increased knowledge and heightened perceived vulnerability mediated changes in simulated behavior suggests the dual roles of knowledge and appraisal on children's injury-risk behavior.

2011-01-01
On the basis of hypotheses derived from social and experiential learning theories, we meta-analytically investigated how safety training and workplace hazards impact the development of safety knowledge and safety performance. The results were consistent with an expected interaction between the level of engagement of safety training and hazardous event/exposure severity in the promotion of safety knowledge and performance. For safety knowledge and safety performance, highly engaging training was considerably more effective than less engaging training when hazardous event/exposure severity was high, whereas highly and less engaging training had comparable levels of effectiveness when hazardous event/exposure severity was low. Implications of these findings for theory testing and incorporating information on objective risk into workplace safety research and practice are discussed.

Consumer implementation of recommended food safety practices, specifically relating to time and temperature control of ready-to-eat (RTE) food products associated with listeriosis are crucial. This is particularly the case for at-risk consumers such as older adults, given the increased listeriosis incidence reported internationally among adults aged ≥60 years. However, data detailing older adults' cognitive risk factors associated with listeriosis are lacking. Combining data about knowledge, self-reported practices, and attitudes can achieve a cumulative multilayered in-depth understanding of consumer food safety behavior and cognition. This study aims to ascertain older adults' cognition and behavior in relation to domestic food handling and storage practices that may increase the risks associated with L. monocytogenes. Older adults (≥60 years) (n = 100) participated in an interview and questionnaire to determine knowledge, self-reported practices, and attitudes toward recommended practices. Although the majority (79%) had positive attitudes toward refrigeration, 84% were unaware of recommended temperatures (5°C) and 65% self-reported "never" checking their refrigerator temperature. Although most (72%) knew that "use-by" dates indicate food safety and 62% reported "always" taking note, neutral attitudes were held, with 67% believing it was safe to eat food beyond use-by dates and 57% reporting doing so. Attitudes toward consuming foods within the recommended 2 days of opening were neutral, with 55% aware of recommendations and , 84% reporting that they consume RTE foods beyond recommendations. Although knowledgeable of some key practices, older adults self-reported potentially unsafe practices when storing RTE foods at home, which may increase risks associated with L. monocytogenes. This study has determined that older adults' food safety cognition may affect their behaviors; understanding consumer food safety cognition is essential for developing targeted food safety education.

Food preparation and storage behaviors in the home deviating from the "best practice" food safety recommendations may result in foodborne illnesses. Currently, there are limited tools available to fully evaluate the consumer knowledge, perceptions, and behavior in the area of refrigerator safety. The current study aimed to develop a valid and reliable tool in the form of a questionnaire, the Consumer Refrigerator Safety Questionnaire (CRSQ), for assessing systematically all these aspects. Items relating to refrigerator safety knowledge (n =17), perceptions (n =46), and reported behavior (n =30) were developed and pilot tested by an expert reference group and various consumer groups to assess face and content validity (n =20), item difficulty and consistency (n =55), and construct validity (n =23). The findings showed that the CRSQ has acceptable face and content validity with acceptable levels of item difficulty. Item consistency was observed for 12 of 15 in refrigerator safety knowledge. Further, all 5 of the subscales of consumer perceptions of refrigerator safety practices relating to risk of developing foodborne disease showed acceptable internal consistency (Cronbach's α value > 0.8). Construct validity of the CRSQ was shown to be very good (P = 0.022). The CRSQ exhibited acceptable test-retest reliability at 14 days with the majority of knowledge items (93.3%) and reported behavior items (96.4%) having correlation coefficients of greater than 0.70. Overall, the CRSQ was deemed valid and reliable in assessing refrigerator safety knowledge and behavior; therefore, it has the potential for future use in identifying groups of individuals at increased risk of deviating from recommended refrigerator safety practices, as well as the assessment of refrigerator safety knowledge and behavior for use before and after an intervention.

Earlier studies of ski injury indicated that youths were at increased risk of injury, that males were most likely to injure the head or face, and that females were most likely to injure the knee. To obtain information about safety knowledge and risk behaviour that might contribute to injury among young skiers and snow-boarders. Survey of knowledge and behaviour in injured and noninjured cohorts. Blackcomb Mountain, Whistler, British Columbia. A total of 863 noninjured and 118 injured skiers and snowboarders aged five to 17 years using Blackcomb during 1993/94. Skier Knowledge Inventory Questionnaire. The injured cohort had less knowledge of the Skiers Responsibility Code. In both groups, almost half had had no lessons, 31% had had bindings adjusted by nonprofessionals and chair lift safety bars were used one ride in four by children age 13 to 17 years. The injuried cohort wore helmets slightly less often. Both groups regularly skied through the trees (60% to 70%), and one-thirds had skied on closed runs. Excessive speed was identified as the major cause of injury. Skiers did not recognize jumping as contributing to injury. Lack of knowledge of safety rules was more prevalent among the injured cohort. Skiing without due care - including skiing through tress, skiing on closed runs, skiing with excessive speed and jumping, particularly by snowboarders - were identified as potential causes of injury.

Children are at a higher risk for foodborne illness. The objective of this study was to explore food safety knowledge, beliefs and practices among Hispanic families with young children (≤10 years of age) living within a Midwestern state. A convergent mixed methods design collected qualitative and quantitative data in parallel. Food safety knowledge surveys were administered (n = 90) prior to exploration of beliefs and practices among six focus groups (n = 52) conducted by bilingual interpreters in community sites in five cities/towns. Descriptive statistics determined knowledge scores and thematic coding unveiled beliefs and practices. Data sets were merged to assess concordance. Participants were female (96%), 35.7 (±7.6) years of age, from Mexico (69%), with the majority having a low education level. Food safety knowledge was low (56% ± 11). Focus group themes were: Ethnic dishes popular, Relating food to illness, Fresh food in home country, Food safety practices, and Face to face learning. Mixed method analysis revealed high self confidence in preparing food safely with low safe food handling knowledge and the presence of some cultural beliefs. On-site Spanish classes and materials were preferred venues for food safety education. Bilingual food safety messaging targeting common ethnic foods and cultural beliefs and practices is indicated to lower the risk of foodborne illness in Hispanic families with young children.

An Assessment of Food Safety Needs of Restaurants in Owerri, Imo State, Nigeria
Onyeneho, Sylvester N.; Hedberg, Craig W.
2013-01-01
One hundred and forty five head chefs and catering managers of restaurants in Owerri, Nigeria were surveyed to establish their knowledge of food safety hazards and control measures. Face-to-face interviews were conducted and data collected on their knowledge of risk perception, food handling practices, temperature control, foodborne pathogens, and personal hygiene. Ninety-two percent reported that they clean and sanitize food equipment and contact surfaces while 37% engaged in cross-contamination practices. Forty-nine percent reported that they would allow a sick person to handle food. Only 70% reported that they always washed their hands while 6% said that they continued cooking after cracking raw eggs. All respondents said that they washed their hands after handling raw meat, chicken or fish. About 35% lacked knowledge of ideal refrigeration temperature while 6% could not adjust refrigerator temperature. Only 40%, 28%, and 21% had knowledge of Salmonella, E. coli, and Hepatitis A, respectively while 8% and 3% had knowledge of Listeria and Vibrio respectively, as pathogens. Open markets and private bore holes supplied most of their foods and water, respectively. Pearson’s Correlation Coefficient analysis revealed almost perfect linear relationship between education and knowledge of pathogens (r = 0.999), cooking school attendance and food safety knowledge (r = 0.992), and class of restaurant and food safety knowledge (r = 0.878). The lack of current knowledge of food safety among restaurant staff highlights increased risk associated with fast foods and restaurants in Owerri. PMID:23917815

To develop and evaluate the efficacy of an online continuing education course for professionals who provide food safety information to high-risk populations. A 2-credit graduate-level class was converted into six web-based modules (overview of foodborne illness, immunology, pregnancy, human immunodeficiency virus, cancer and transplants, and lifecycle) and offered to nutrition and health professionals. Participants had 8 weeks to complete the modules, pre and post questionnaires, and course evaluation. Those who successfully completed the protocol received six continuing education units from one of three professional associations. Change in knowledge was measured using pre and post questionnaires. Course efficacy was evaluated using a post-course questionnaire. A convenience sample of 140 registered dietitians/dietetic technicians registered, nurses, and extension educators were recruited through professional conferences and electronic mailing lists to take the course. Analysis of variance was used to evaluate differences in knowledge scores for all groups across five main effects (attempt, module, profession, age, and education). Course evaluation responses were used to assess course effectiveness. For each module, knowledge scores increased significantly (P<0.001) from pre to post questionnaire. Overall, knowledge scores increased from 67.3% before the modules to 91.9% afterwards. Course evaluation responses were favorable, and participants indicated that course objectives were met. Online continuing education courses, such as "Food Safety Issues for High Risk Populations," seem to be a convenient, effective option for dietetics professionals, nurses, and extension educators seeking knowledge about food safety issues of high-risk populations. Online learning is a promising delivery approach for the continuing education of health professionals.

Objective This study compared knowledge and food-handling behavior after pathogen-specific (experimental treatment) versus basic food safety instruction (active control) presented during nutrition education classes for low-income English- and Spanish-language pregnant women. Methods Subjects (n = 550) were randomly assigned to treatment groups in two different locations in the United States. Food safety instruction was part of an 8-lesson curriculum. Food safety knowledge and behavior were measured pre/post intervention. Descriptive data were analyzed by Chi-Square or ANOVA; changes after intervention were analyzed by regression analysis. Results Knowledge improved after intervention in the pathogen-specific treatment group compared to active control, especially among Spanish-language women. Behavior change after intervention for the pathogen-specific treatment group improved for thermometer usage, refrigeration and consumption of foods at high risk for safety; however, all other improvements in behavior were accounted for by intervention regardless of treatment group. As expected, higher pre-instruction behavioral competency limited potential gain in behavior post-instruction due to a ceiling effect. This effect was more dominant among English-language women. Improvements were also linked to formal education completed, a partner at home, and other children in the home. Conclusions for Practice This study demonstrated that pathogen-specific food safety instruction leads to enhance knowledge and food handling behaviors that may improve the public health of pregnant women and their unborn children, especially among Spanish-language women. More importantly, food safety instruction, even at the most basic level, benefited pregnant women's food safety knowledge and food-handling behavior after intervention.

Farmworkers face a variety of risk factors for eye injuries. Measures of eye protection use and of eye safety knowledge and beliefs are based on a survey of 300 Latino farmworkers in North Carolina. Few farmworkers report using eye protection (8.3%); most (92.3%) report that employers do not provide eye protection. Approximately 70% report that they are not trained in preventing eye injuries; 81% believe that their chances of getting an eye injury are low. Many farmworkers choose to take risks in order to save time. Interventions are needed that target farmworker knowledge and beliefs about eye safety. PMID:21462026

Risk analysis is increasingly promoted as a tool to support science-based decisions regarding food safety. An online survey comprising 45 questions was used to gather information on the implementation of food safety risk analysis within the Latin American and Caribbean regions. Professionals working in food safety in academia, government, and private sectors in Latin American and Caribbean countries were contacted by email and surveyed to assess their individual knowledge of risk analysis and perceptions of its implementation in the region. From a total of 279 participants, 97% reported a familiarity with risk analysis concepts; however, fewer than 25% were able to correctly identify its key principles. The reported implementation of risk analysis among the different professional sectors was relatively low (46%). Participants from industries in countries with a long history of trade with the United States and the European Union, such as Mexico, Brazil, and Chile, reported perceptions of a higher degree of risk analysis implementation (56, 50, and 20%, respectively) than those from the rest of the countries, suggesting that commerce may be a driver for achieving higher food safety standards. Disagreement among respondents on the extent of the use of risk analysis in national food safety regulations was common, illustrating a systematic lack of understanding of the current regulatory status of the country. The results of this survey can be used to target further risk analysis training on selected sectors and countries.

Developing tailored and effective food safety education for young adults is critical given their future roles as caregivers likely to be preparing food for populations who may be at greater risk for foodborne disease (FBD). The objective of this study was to examine the relationship between food safety self-reported food-handling behaviors and cognitions of young adults to observed food-handling behaviors. Participants were 153 young adults (mean age 20.74+/-1.30 s.d.) attending a major American university. Each prepared a meal under observation in a controlled laboratory setting, permitted researchers to observe their home kitchen and completed an online survey assessing food safety knowledge, behavior and psychosocial measures. Descriptive statistics were generated for participants' self-reported food-handling behaviors, psychosocial characteristics, knowledge, food preparation observations and home kitchen observations. Determinants of compliance with safe food-handling procedures while preparing a meal and home food storage/rotation practices were identified using backward regression models. Participants engaged in less than half of the recommended safe food-handling practices evaluated and correctly answered only two-thirds of the food safety knowledge items. They reported positive food safety beliefs and high food safety self-efficacy. Self-reported compliance with cross-contamination prevention, disinfection procedures and knowledge of groups at greatest risk for FBD were the best measures for predicting compliance with established safe food-handling practices. Food safety education directed toward young adults should focus on increasing awareness of FBD and knowledge of proper cross-contamination prevention procedures to help promote better compliance with actual safe food handling.

Fire is a leading cause of unintentional injury and, although young children are at particularly increased risk, there are very few evidence-based resources available to teach them fire safety knowledge and behaviors. Using a pre-post randomized design, the current study evaluated the effectiveness of a computer game (The Great Escape) for teaching fire safety information to young children (3.5-6 years). Using behavioral enactment procedures, children's knowledge and behaviors related to fire safety were compared to a control group of children before and after receiving the intervention. The results indicated significant improvements in knowledge and fire safety behaviors in the intervention group but not the control. Using computer games can be an effective way to promote young children's understanding of safety and how to react in different hazardous situations.

While workers' safety risk tolerances have been regarded as a main reason for their unsafe behaviors, little is known about why different people have different risk tolerances even when confronting the same situation. The aim of this research is to identify the critical factors and paths that influence workers' safety risk tolerance and to explore how they contribute to accident causal model from a system thinking perceptive. A number of methods were carried out to analyze the data collected through interviews and questionnaire surveys. In the first and second steps of the research, factor identification, factor ranking and factor analysis were carried out, and the results show that workers' safety risk tolerance can be influenced by four groups of factors, namely: (1) personal subjective perception; (2) work knowledge and experiences; (3) work characteristics; and (4) safety management. In the third step of the research, hypothetical influencing path model was developed and tested by using structural equation modeling (SEM). It is found that the effects of external factors (safety management and work characteristics) on risk tolerance are larger than that of internal factors (personal subjective perception and work knowledge & experiences). Specifically, safety management contributes the most to workers' safety risk tolerance through its direct effect and indirect effect; while personal subjective perception comes the second and can act as an intermedia for work characteristics. This research provides an in-depth insight of workers' unsafe behaviors by depicting the contributing factors as shown in the accident causal model developed in this research.

With limited opportunities to learn safe food handling via observation, many young adults lack the knowledge needed to keep them safe from foodborne disease. It is important to reach young adults with food safety education because of their current and future roles as caregivers. With a nationwide online survey, the demographic characteristics, self-reported food handling and consumption behaviors, food safety beliefs, locus of control, self-efficacy, stage of change, and knowledge of young adults with education beyond high school (n = 4,343) were assessed. Young adults (mean age, 19.92 +/- 1.67 SD) who participated were mainly female, white, never married, and freshmen or sophomores. Participants correctly answered 60% of the knowledge questions and were most knowledgeable about groups at greatest risk for foodborne disease and least knowledgeable about common food sources of foodborne disease pathogens. They reported less than optimal levels of safe food handling practices. Young adults generally had a limited intake of foods that increase the risk of foodborne disease, positive food safety beliefs, an internal food safety locus of control, and confidence in their ability to handle food safely, and they were contemplating an improvement in, or preparing to improve, their food handling practices. Females significantly outperformed males on nearly all study measures. Future food safety educational efforts should focus on increasing knowledge and propelling young adults into the action stage of safe food handling, especially males. Efforts to improve knowledge and, ultimately, food safety behaviors are essential to safeguard the health of these young adults and enable them to fulfill the role of protecting the health of their future families.

BACKGROUND: Earlier studies of ski injury indicated that youths were at increased risk of injury, that males were most likely to injure the head or face, and that females were most likely to injure the knee. OBJECTIVE: To obtain information about safety knowledge and risk behaviour that might contribute to injury among young skiers and snow-boarders. DESIGN: Survey of knowledge and behaviour in injured and noninjured cohorts. SETTING: Blackcomb Mountain, Whistler, British Columbia. PARTICIPANTS: A total of 863 noninjured and 118 injured skiers and snowboarders aged five to 17 years using Blackcomb during 1993/94. INTERVENTION: Skier Knowledge Inventory Questionnaire. RESULTS: The injured cohort had less knowledge of the Skiers Responsibility Code. In both groups, almost half had had no lessons, 31% had had bindings adjusted by nonprofessionals and chair lift safety bars were used one ride in four by children age 13 to 17 years. The injuried cohort wore helmets slightly less often. Both groups regularly skied through the trees (60% to 70%), and one-thirds had skied on closed runs. Excessive speed was identified as the major cause of injury. Skiers did not recognize jumping as contributing to injury. CONCLUSIONS: Lack of knowledge of safety rules was more prevalent among the injured cohort. Skiing without due care – including skiing through tress, skiing on closed runs, skiing with excessive speed and jumping, particularly by snowboarders – were identified as potential causes of injury.

Development is defined sustainable when it meets the needs of the present without compromising the ability of future generations to meet their own needs. Pivoting on social, environmental and economic aspects of food chain sustainability, this paper presents the concept of sustainable food safety based on the prevention of risks and burden of poor health for generations to come. Under this respect, the assessment of long-term, transgenerational risks is still hampered by serious scientific uncertainties. Critical issues to the development of a sustainable food safety framework may include: endocrine disrupters as emerging contaminants that specifically target developing organisms; toxicological risks assessment in Countries at the turning point of development; translating knowledge into toxicity indexes to support risk management approaches, such as hazard analysis and critical control points (HACCP); the interplay between chemical hazards and social determinants. Efforts towards the comprehensive knowledge and management of key factors of sustainable food safety appear critical to the effectiveness of the overall sustainability policies.
The Toxic Truth About Carbon Nanotubes in Water Purification: a Perspective View.
Das, Rasel; Leo, Bey Fen; Murphy, Finbarr
2018-06-18
Without nanosafety guidelines, the long-term sustainability of carbon nanotubes (CNTs) for water purifications is questionable. Current risk measurements of CNTs are overshadowed by uncertainties. New risks associated with CNTs are evolving through different waste water purification routes, and there are knowledge gaps in the risk assessment of CNTs based on their physical properties. Although scientific efforts to design risk estimates are evolving, there remains a paucity of knowledge on the unknown health risks of CNTs. The absence of universal CNT safety guidelines is a specific hindrance. In this paper, we close these gaps and suggested several new risk analysis roots and framework extrapolations from CNT-based water purification technologies. We propose a CNT safety clock that will help assess risk appraisal and management. We suggest that this could form the basis of an acceptable CNT safety guideline. We pay particular emphasis on measuring risks based on CNT physico-chemical properties such as diameter, length, aspect ratio, type, charge, hydrophobicity, functionalities and so on which determine CNT behaviour in waste water treatment plants and subsequent release into the environment.

Objective Dog-bite injuries pose significant threat to children globally. School-aged children are especially at risk because of their cognitively immature tendency toward low perceived vulnerability to bites, and this risk is elevated further for school-aged children living in rural China due to the large number of stray dogs, all potential rabies carriers, present in their communities. Methods This randomized controlled trial evaluated whether viewing an educational video of testimonials would change safety knowledge, perceived vulnerability, and simulated behaviors with dogs among a sample of 280 third and fourth graders living in rural China. Participants were randomly assigned to view either an educational video of testimonials on dog-bite prevention (treatment) or an educational video of testimonials on drowning prevention (comparison). Safety knowledge, perceived vulnerability to dog bites, and simulated behavior with dogs using a dollhouse model were assessed both before and after exposure to the video of testimonials. Results Children who watched the educational video of testimonials on dog-bite prevention had increased safety knowledge, higher perceived vulnerability, and less risky simulated behaviors with dogs compared to the comparison group. Mediation analysis revealed that the intervention successfully changed children's simulated behaviors with dogs through greater safety knowledge and increased perceived vulnerability. Conclusions Results suggest the incorporation of testimonials into injury prevention programs has potential for broad global dissemination. The fact that both increased knowledge and heightened perceived vulnerability mediated changes in simulated behavior suggests the dual roles of knowledge and appraisal on children's injury-risk behavior.

To explore nurses' experiences with and perspectives on preventing medication administration errors. Insight into nurses' experiences with and perspectives on preventing medication administration errors is important and can be utilised to tailor and implement safety practices. A qualitative interview study of 20 nurses in an academic medical centre was conducted between March and December of 2011. Three themes emerged from this study: (1) nurses' roles and responsibilities in medication safety: aside from safe preparation and administration, the clinical reasoning of nurses is essential for medication safety; (2) nurses' ability to work safely: knowledge of risks and nurses' work circumstances influence their ability to work safely; and (3) nurses' acceptance of safety practices: advantages, feasibility and appropriateness are important incentives for acceptance of a safety practice. Nurses' experiences coincide with the assumption that they are in a pre-eminent position to enable safe medication management; however, their ability to adequately perform this role depends on sufficient knowledge to assess the risks of medication administration and on the circumstances in which they work. Safe medication management requires a learning climate and professional practice environment that enables further development of professional nursing skills and knowledge. © 2014 John Wiley & Sons Ltd.

Practice-specific risk perceptions and self-reported food safety practices.
Levy, Alan S; Choinière, Conrad J; Fein, Sara B
2008-06-01
The relationship between risk perception and risk avoidance is typically analyzed using self-reported measures. However, in domains such as driving or food handling, the validity of responses about usual behavior is threatened because people think about the situations in which they are self-aware, such as when they encounter a hazard. Indeed, researchers have often noted a divergence between what people say about their behavior and how they actually behave. Thus, in order to draw conclusions about risk perceptions and risk avoidance from survey data, it is important to identify particular cognitive elements, such as those measured by questions about risk and safety knowledge, risk perceptions, or information search behavior, which may be effective antecedents of self-reported safety behavior. It is also important to identify and correct for potential sources of bias that may exist in the data. The authors analyze the Food and Drug Administration's 1998 Food Safety Survey to determine whether there are consistent cognitive antecedents for three types of safe food practices: preparation, eating, and cooling of foods. An assessment of measurement biases shows that endogeneity of food choices affects reports of food preparation. In addition, response bias affects reports of cooling practices as evidenced by its relation to knowledge and information search, a pattern of cognitive effects unique to cooling practices. After correcting for these biases, results show that practice-specific risk perceptions are the primary cognitive antecedents of safe food behavior, which has implications for the design of effective education messages about food safety.
Public risk perception of food additives and food scares. The case in Suzhou, China.
Wu, Linhai; Zhong, Yingqi; Shan, Lijie; Qin, Wei
2013-11-01
This study examined the factors affecting public risk perception of food additive safety and possible resulting food scares using a survey conducted in Suzhou, Jiangsu Province, China. The model was proposed based on literature relating to the role of risk perception and information perception of public purchase intention under food scares. Structural equation modeling (SEM) was used for data analysis. The results showed that attitude towards behavior, subjective norm and information perception exerted moderate to high effect on food scares, and the effects were also mediated by risk perceptions of additive safety. Significant covariance was observed between attitudes toward behavior, subjective norm and information perception. Establishing an effective mechanism of food safety risk communication, releasing information of government supervision on food safety in a timely manner, curbing misleading media reports on public food safety risk, and enhancing public knowledge of the food additives are key to the development and implementation of food safety risk management policies by the Chinese government.

Walking to school could improve pupils' health condition and might also reduce the use of motorized transport modes, which leads to both traffic congestion and air pollution. The current study aims to examine the role of parental risk judgements (i.e. risk perception and worry), transport safety attitudes, transport priorities and accident experiences on pupils' walking and mode choices on school trips in Iran, a country with poor road safety records. A total of 1078 questionnaires were randomly distributed among pupils at nine public and private schools in January 2014 in Rasht, Iran. Results from valid observations (n=711) showed that parents with high probability assessments of accidents and strong worry regarding pupils' accident risk while walking were less likely to let their children walk to school. Parents with high safety knowledge were also more likely to allow their pupils to walk to school. Parents who prioritized convenience and accessibility in transport had a stronger tendency to choose motorized modes over walking modes. Also, parents who prioritized safety and security in transport were less likely to allow pupils to walk to school. Elasticities results showed that a one percent increase in priorities of convenience and accessibility, priorities of safety and security, car ownership and walking time from home to school reduced walking among pupils by a probability of 0.62, 0.20, 0.86 and 0.57%, respectively. A one percent increase in parental safety knowledge increased the walking probability by around 0.25%. A 1 unit increase in parental probability assessment and worry towards pupils' walking, decreased the probability of choosing walking mode by 0.11 and 0.05, respectively. Policy-makers who aim to promote walking to schools should improve safety and security of the walking facilities and increase parental safety knowledge. Copyright © 2017 Elsevier Ltd.

We adopted a comparative approach to evaluate and extend a generic methodology to analyze the different sets of beliefs held about chemical hazards in the workplace. Our study mapped existing knowledge structures about the risks associated with the use of perchloroethylene and rosin-based solder flux in differing workplaces. "Influence diagrams" were used to represent beliefs held by chemical experts; "user models" were developed from data elicited from open-ended interviews with the workplace users of the chemicals. The juxtaposition of expert and user understandings of chemical risks enabled us to identify knowledge gaps and misunderstandings and to reinforce appropriate sets of safety beliefs and behavior relevant to chemical risk communications. By designing safety information to be more relevant to the workplace context of users, we believe that employers and employees may gain improved knowledge about chemical hazards in the workplace, such that better chemical risk management, self-protection, and informed decision making develop over time.

Risk assessment and safety planning are considered a cornerstone of mental health practice, yet limited research exists into how mental health nurses conceptualize 'risk' and how they engage with risk assessment and safety planning. The aim of the present study was to explore mental health nurses' practices and confidence in risk assessment and safety planning. A self-completed survey was administered to 381 mental health nurses in Ireland. The findings indicate that nurses focus on risk to self and risk to others, with the risk of suicide, self-harm, substance abuse, and violence being most frequently assessed. Risk from others and 'iatrogenic' risk were less frequently considered. Overall, there was limited evidence of recovery-oriented practice in relation to risk. The results demonstrate a lack of meaningful engagement with respect to collaborative safety planning, the identification and inclusion of protective factors, and the inclusion of positive risk-taking opportunities. In addition, respondents report a lack of confidence working with positive risk taking and involving family/carers in the risk-assessment and safety-planning process. Gaps in knowledge about risk-assessment and safety-planning practice, which could be addressed through education, are identified, as are the implications of the findings for practice and research. © 2015 Australian College of Mental Health Nurses Inc.

The objective of this study is to gather statistical references on food safety education that encourages competence of food choice from the view-point of food safety. A survey on the involvement of the risk communication program on food safety in municipal governments and the attitude of local dietetics professionals towards the program was conducted. In November, 2006, self-reported questionnaires were mailed to 1990 local dietetics professionals who worked in municipal governments in Japan. Descriptive statistics and cross tables were used for data analysis. 1162 questionnaires were mailed and 1130 available surveys were returned. Among the respondents, 41.5% answered that they inform the community about food safety, but 49.9% answered that they did not get information from the community. Most of the respondents answered that risk communication of food safety was important; 21.8% answered "extremely agree" and 62.3% answered "rather agree" on a scale of four from "extremely agree" to "do not agree". More than one-half of the dietetics professionals answered that their confidence in conducting risk communication was low; 20.5% answered "no confidence" and 52.5% answered "hardly have confidence" on a scale of four from "without confidence" to "with confidence". More than 80% of the respondents answered that they needed "professional knowledge" and "support from professional agencies". This study suggests that educating local dietetics professionals about professional knowledge on food safety, and obtaining support from special agencies will be essential in the upgrade of risk communication program on food safety in a community.
Exploring the use of situation awareness in behaviors and practices of health and safety leaders.

An understanding of how health and safety management systems (HSMS) reduce worksite injuries, illnesses and fatalities may be gained in studying the behaviors of health and safety leaders. These leaders bear the accountability for identifying, understanding and managing the risks of a mining operation. More importantly, they have to transfer this knowledge of perception, recognition and response to risks in the mining environment to their workers. The leaders' efforts to build and maintain a mining operation's workforce that consistently executes safe work practices may be captured through more than just lagging indicators of health and safety performance. This exploratory study interviewed six leaders in occupations such as site-level safety supervisors, mine superintendents and/or general managers at surface and underground stone, sand and gravel and metal/nonmetal mine sites throughout the United States, with employee populations ranging from 40 to 175. In exploring leaders' perspectives on how they systematically manage health and safety, examples such as approaches to task training, handling near-miss incidents, identifying future leaders and providing workers with feedback offer insights into how leaders translate their knowledge and management of site-level risks to others.

Among agricultural workers, migrant and seasonal farmworkers have been recognized as a special risk population because these laborers encounter cultural challenges and linguistic barriers while attempting to maintain their safety and health within their working environments. The crop-specific Pesticides and Farmworker Health Toolkit (Toolkit) is a pesticide safety and health curriculum designed to communicate to farmworkers pesticide hazards commonly found in their working environments and to address Worker Protection Standard (WPS) pesticide training criteria for agricultural workers. The goal of this preliminary study was to test evaluation items for measuring knowledge increases among farmworkers and to assess the effectiveness of the Toolkit in improving farmworkers' knowledge of key WPS and risk communication concepts when the Toolkit lesson was delivered by trained trainers in the field. After receiving training on the curriculum, four participating trainers provided lessons using the Toolkit as part of their regular training responsibilities and orally administered a pre- and post-lesson evaluation instrument to 20 farmworker volunteers who were generally representative of the national farmworker population. Farmworker knowledge of pesticide safety messages significantly (P<.05) increased after participation in the lesson. Further, items with visual alternatives were found to be most useful in discriminating between more and less knowledgeable farmworkers. The pilot study suggests that the Pesticides and Farmworker Health Toolkit is an effective, research-based pesticide safety and health intervention for the at-risk farmworker population and identifies a testing format appropriate for evaluating the Toolkit and other similar interventions for farmworkers in the field.

Aviation is a problem domain characterized by a high level of system complexity and uncertainty. Safety risk analysis in such a domain is especially challenging given the multitude of operations and diverse stakeholders. The Federal Aviation Administration (FAA) projects that by 2025 air traffic will increase by more than 50 percent with 1.1 billion passengers a year and more than 85,000 flights every 24 hours contributing to further delays and congestion in the sky (Circelli, 2011). This increased system complexity necessitates the application of structured safety risk analysis methods to understand and eliminate where possible, reduce, and/or mitigate risk factors. The use of expert judgments for probabilistic safety analysis in such a complex domain is necessary especially when evaluating the projected impact of future technologies, capabilities, and procedures for which current operational data may be scarce. Management of an R&D product portfolio in such a dynamic domain needs a systematic process to elicit these expert judgments, process modeling results, perform sensitivity analyses, and efficiently communicate the modeling results to decision makers. In this paper a case study focusing on the application of an R&D portfolio of aeronautical products intended to mitigate aircraft Loss of Control (LOC) accidents is presented. In particular, the knowledge elicitation process with three subject matter experts who contributed to the safety risk model is emphasized. The application and refinement of a verbal-numerical scale for conditional probability elicitation in a Bayesian Belief Network (BBN) is discussed. The preliminary findings from this initial step of a three-part elicitation are important to project management practitioners as they illustrate the vital contribution of systematic knowledge elicitation in complex domains.

Listeria monocytogenes causes human listeriosis, which is associated with the highest hospitalization and mortality rates of all foodborne illnesses. In recent years, the incidence of listeriosis has doubled in Europe, almost exclusively among older adults (≥ 60 years of age). Food safety factors associated with increased risk of listeriosis include lack of adherence to "use by" dates and ineffective refrigerated storage of foods. Consequently, older adult consumers' implementation of safe food practices should be evaluated. This article is a review of consumer food safety cognitive and behavioral data relating to risk factors associated with listeriosis in the home as reported in 165 consumer food safety studies. Overall, only 41% of studies included assessment of consumer cognitive or behavioral data associated with listeriosis; of these studies 59% included data on safe refrigeration, 54% included data on storage time for opened ready-to-eat foods, and 49% included data on adherence to use-by dates. In most (83%) of the studies, survey-based data collection methods (questionnaires/interviews) were used; thus, the majority of findings were based on self-report (74%) and knowledge (44%). Observation (31%) and focus groups (12%) were less commonly used, resulting in a lack of actual behaviors and attitudinal data relating to listeriosis risk factors. Only 7% of studies included food safety data for older adults. Although older adults may fail to implement recommended practices, this review reveals a need for in-depth research to determine food safety attitudes and actual behaviors of older adults in conjunction with knowledge and selfreport of practices linked to increased risks of listeriosis. Such data combined with review findings would inform targeted food safety education to reduce risks associated with listeriosis in the home.
Workers' understanding of chemical risks: electroplating case study

Background: There is limited research concerning how small companies in particular, respond to health and safety messages. Aims: To understand individuals' knowledge and beliefs about chemical risks and to compare these with those of experts. Methods: The use of chromic acid in particular, and also other chemicals associated with chrome plating were studied. All chromium plating firms were based in the West Midlands. The methodology involved initial face to face interviews (n = 21) with chromium platers, structured questionnaires (n = 84) to test the prevalence of beliefs identified in the interviews, an expert questionnaire, and a workshop to discuss findings. The responses of platers were compared with those of occupational health and safety experts. Results: Although chromium platers appeared to understand the short term adverse effects of the chemicals to which they are exposed, their understanding of long term, or chronic effects appeared to be incomplete. They had good knowledge of acute effects based primarily on experience. Platers were aware of the hazardous nature of the chemicals with which they work, but did not draw distinction between the terms "hazards" and "risks". They had difficulties articulating the effects of the chemicals and how exposure might occur; although it is inappropriate to equate this with lack of knowledge. A significant minority of platers displayed deficiencies in understanding key technical terms used in Safety Data Sheets. Conclusions: This study provides a method which can be used to gain some understanding of workers' knowledge and beliefs about risks that they are exposed to in the workplace. The study also identifies gaps between the platers' knowledge and beliefs and those of experts. New risk information needs to be designed which addresses the information needs of platers using language that they understand. PMID:12356930

This exploratory research examined the benefits of a health education program utilizing the Home Safety Self-Assessment Tool (HSSAT) to increase perceived knowledge of home safety, recognition of unsafe activities, ability to safely perform activities, and develop home safety plans of 47 older adults. Focus groups in two senior centers explored social workers' perspectives on use of the HSSAT in community practice. Results for the health education program found significant differences between reported knowledge of home safety (p = .02), ability to recognize unsafe activities (p = .01), safely perform activities (p = .04), and develop a safety plan (p = .002). Social workers identified home safety as a major concern and the HSSAT a promising assessment tool. Research has implications for reducing environmental fall risks.

In Australia, more than 30% of the traffic volume can be attributed to work-related vehicles. Although work-related driver safety has been given increasing attention in the scientific literature, it is uncertain how well this knowledge has been translated into practice in industry. It is also unclear how current practice in industry can inform scientific knowledge. The aim of the research was to use a benchmarking tool developed by the National Road Safety Partnership Program to assess industry maturity in relation to risk management practices. A total of 83 managers from a range of small, medium and large organisations were recruited through the Victorian Work Authority. Semi-structured interviews aimed at eliciting information on current organisational practices, as well as policy and procedures around work-related driving were conducted and the data mapped onto the benchmarking tool. Overall, the results demonstrated varying levels of maturity of risk management practices across organisations, highlighting the need to build accountability within organisations, improve communication practices, improve journey management, reduce vehicle-related risk, improve driver competency through an effective workplace road safety management program and review organisational incident and infringement management. The findings of the study have important implications for industry and highlight the need to review current risk management practices. Copyright © 2016 Elsevier Ltd. All rights reserved.

2012-01-01
The large-scale use of agrochemicals has raised environmental and human health concerns. A comprehensive intervention strategy for improving agrochemical safety among rice farmers in Thailand is lacking. The objective of this study is to develop a model in order to improve farmers’ health and prevent them from being exposed to agrochemical hazards, in addition to evaluating the effectiveness of the intervention in terms of agrochemical safety. This study was conducted between October 2009 and January 2011. It measures changes in the mean scores of agrochemical knowledge, health beliefs, agrochemical use behaviors, and in-home pesticide safety. Knowledge of agrochemical use constitutes a basic knowledge of agrochemicals and agrochemical safety behaviors. Health beliefs constitute perceived susceptibility, severity, benefits, and barriers to using agrochemicals. Agrochemical use behaviors include self-care practices in terms of personal health at specific times including before spraying, while spraying, during storage, transportation, waste management, and health risk management. Fifty rice farmers from Khlong Seven Community (study group) and 51 rice farmers from Bueng Ka Sam community (control group) were randomly recruited with support from community leaders. The participants were involved in a combination of home visits (ie, pesticide safety assessments at home) and community participatory activities regarding agrochemical safety. This study reveals that health risk behaviors regarding agrochemical exposure in the study area are mainly caused by lack of attention to safety precautions and the use of faulty protective gear. After 6 months, the intervention program showed significant improvements in the overall scores on knowledge, beliefs, behaviors, and home pesticide safety in the study group (P < 0.05). Therefore, this intervention model is effective in improving agrochemical safety behaviors among Khlong Seven Community rice farmers. These findings demonstrate that a multi-approach model for improving agrochemical safety behaviors can lead to sustainable prevention of agrochemical hazards for farmers. PMID:22956888

Postal delivery workers spend a large proportion of their work time outdoors, placing them at increased risk of skin cancer. To date, no studies have examined occupational sun safety knowledge and practice within this group in the UK. To describe the occupational sun safety knowledge and practice of UK postal delivery workers and to investigate the association of demographic, personal and occupational factors with knowledge and practice in order to identify potential strategies for improving sun safety in this occupational group. Postal delivery workers completed a questionnaire that collected data on occupational sun safety knowledge and practice in addition to demographic, personal and workplace characteristics. One-way analysis of variances were applied to assess differences in knowledge and practice by these characteristics. A total of 1153 postal delivery workers completed the questionnaire, a 60% response rate. Thirty-three per cent reported receiving sun safety training within the previous 12 months. The majority of respondents reported correct knowledge on three of the six domains and good practice on four of the six behavioural domains. However, only one-fifth of respondents reported wearing sunglasses and ensuring a plentiful intake of water. Knowledge and practice differed significantly according to demographic, personal and workplace characteristics. There is a need to raise the profile of occupational skin cancer in this occupational group and to increase the priority given to occupational sun safety policies alongside targeted and tailored interventions, the effect of which can be evaluated. © The Author 2015.

Objective Parenting practices differ for a variety of reasons, and three parenting behaviors may be directly influenced by research, policy, and overall parenting trends: car safety seats, vaccination, and breastfeeding. Mothers were categorized in terms of their rear-facing car safety seat utilization and its relationship to other parental health and safety behaviors. Methods A cross-sectional, online survey of mothers of children under 3 years of age (n=124) was conducted. Items assessed mother’s perceived risk and worry about being in an automobile accident, as well as duration of rear-facing car seat utilization. A cluster analysis based on these variables was performed to differentiate the sample into four distinct groups. Outcomes were knowledge of car safety seats, breastfeeding duration, and adherence to vaccination schedules. Results The sample was predominantly White, had an average age of 32 years, had breastfed, and had at least some college education. Two groups of interest had (Group 1) long duration of rear-facing use with low perceived risk and worry and (Group 2) short use with high perceived risk and worry. Fisher’s Exact test indicated Group 1 had higher knowledge of airbag use with car seats (p=0.035), lower intentions to use the recommended vaccinations schedule (p=0.005), and were more likely to breastfeed (p=0.044) for longer duration (p=0.012). Conclusion Propensity for mothers’ risk aversion may be the crucial element in both an appropriate duration of rear-facing car safety seat use and refusal of recommended vaccination schedule.

Young male and female workers are over-represented in statistics concerning negative outcomes of poor work environment and risky work. Young workers often have low awareness of risk, a lack of safety training, and inadequate introduction to the work. The aim of this study was to identify the knowledge and experiences of pupils of vocational schools concerning potential work environment risks in their future work. The study design was a dual one, and included a questionnaire and focus group interviews. The study group consisted of 239 pupils from 10 upper secondary schools, who were graduating pupils in four vocational programs: the Industrial Technology Programme, the Restaurant Management and Food Programme, the Transport Programme, and the Handicraft Programme (in which students specialize in wood products). The upper secondary schools were located in the central region of Sweden. The pupils had limited knowledge that employers must, by law, conduct risk analyses and prevent risks. Many felt that they themselves are mainly responsible for performing their tasks safely. Pupils in all programs mentioned acute risk as the greatest risk at work. The theoretical education about safety at work was provided in the 1(st) year of the 3-year vocational programs. A systematic approach to pupils' training in work environment, which is a basis for a safe and healthy workplace, is lacking. The study findings indicate that pupils are offered knowledge far from that intended by laws and by state-of-the-art occupational health risk research.

In the U.S., foodborne disease causes millions of illnesses annually, resulting in thousands of deaths. To reduce food poisoning, restaurant food handlers need accurate knowledge of food safety principles as a starting point for the outcome of optimal food safety behavior. The study described in this article determined food safety knowledge gaps among suburban Chicago restaurant food handlers. A cross-sectional survey of 729 food handlers at 211 suburban Chicago restaurants was conducted from June 2009 through February 2010. A 50-question survey was administered by a trained interviewer in either English or Spanish. Mixed-effects regression analysis identified risk factors associated with an overall food safety knowledge score. The mean overall knowledge score was only 72% and substantial knowledge gaps related to cross contamination, cooking, and holding and storage of food were identified. Spanish-speaking food handlers scored significantly lower than English-speaking food handlers (p < .05). Although certified food managers scored significantly higher than noncertified food handlers, their score was only 79%. These data provide targets for educational interventions to remedy knowledge gaps in food handlers in order to prevent food poisoning from restaurants.

Pork safety is an important public health concern in Vietnam and is a shared responsibility among many actors along the pork value chain. We examined the knowledge, perceptions, and practices regarding food safety, disease, and health risk among selected pork value chain actors (slaughterhouse owners and workers, people living around slaughterhouses, pork sellers, consumers, and veterinary and public health staff) in three districts in Hung Yen Province, Vietnam. We randomly selected 52 pork value chain actors to be surveyed through questionnaires, observation checklists, key informant interviews, and focus group discussions. Most slaughterhouse workers acquired knowledge and experience of food safety through "learning by doing" rather than from training by a veterinary or public health professional. Both slaughterhouse worker and pork seller groups had some accurate perceptions about pig diseases and foodborne diseases; however, misperceptions of risk and, especially, of zoonoses were present. Furthermore, while workers and sellers often use cloths to dry the meat and clean equipment, they did not think this was a risk for meat contamination. Moreover, when sellers wear protective equipment, such as gloves, masks, or hats, consumers perceive that the sellers may have health issues they are trying to conceal and so consumers avoid buying from them. The perceived freshness of pork, along with trust in the seller and in the pork production process, were strong indicators of consumer preference. And yet, pork value chain actors tend to trust their own individual food safety practices more, rather than the practices of other actors along the chain. Veterinary and public health staff emphasized the gap between regulations and food safety practices. Education and training on food safety risks and proper handling are priorities, along with integrated and intensive efforts to improve food safety among pork value chain actors.

Diagnostic radiology procedures, such as computed tomography (CT) and X-ray, are an increasing source of ionising radiation exposure to our community. Exposure to ionising radiation is associated with increased risk of malignancy, proportional to the level of exposure. Every diagnostic test using ionising radiation needs to be justified by clinical need. General practitioners need a working knowledge of radiation safety so they can adequately inform their patients of the risks and benefits of diagnostic imaging procedures.
National nanotechnology partnership to protect workers

Nanotechnology is predicted to improve many aspects of human life. By 2015, it is estimated to represent 3.1 trillion in manufactured goods. Data is emerging that exposure to nanomaterials may pose a health risk to workers. If the economic promise of nanotechnology is to be achieved, ways need to be found to protect nanotechnology workers now. The Occupational Safety and Health Act of 1970 (OSHAct) gave the responsibility to protect workers to the Occupational Safety and Health Administration (OSHA) and the National Institute for Occupational Safety and Health (NIOSH) through research, standards adoption, and standards enforcement. Since 1980, adopting new occupational health standards has grown more complex. The increased complexity has greatly slowed efforts to adopt protective standards for toxic agents that are well-known to pose significant risks. The likelihood of rapidly adopting standards to protect workers from nanomaterials, whose risks are just emerging, seems even more unlikely. Use of the OSHAct's general duty clause to protect workers also seems uncertain at this time. In the interim, a national partnership led by NIOSH involving nanotech manufacturers and downstream users, workers, academic researchers, safety, and health practitioners is proposed. A National Nanotechnology Partnership would generate knowledge about the nature and the extent of worker risk, utilize that knowledge to develop risk control strategies to protect nanotechnology workers now, and provide an evidence base for NIOSH recommendations to OSHA for a nanotechnology program standard at a future date.

This survey assessed general practitioners' (GPs') knowledge of and compliance with, health and safety legislation and occupational health guidance in one London health authority. The response rate was 85%. Although the majority of practices were aware of the most important piece of legislation--The Management of Health and Safety at Work Regulations, 1992--less than one in ten practices had carried out the required systematic risk assessments. Compliance with other health and safety legislation and related employment issues was also poor. The health of GPs and their staff may be at risk and these general practices may be vulnerable to prosecution by the Health and Safety Executive. PMID:12236278

Snowmobiling among young people in Scandinavia frequently leads to accidents and injuries. Systematic studies of accidents exist, but few studies have addressed young drivers' experiences. The aim of this article is to reveal how young people experience and interpret accidents, and to outline a prevention strategy. Thirty-one girls and 50 boys aged 16-23 years from secondary schools in Northern Norway and on Svalbard, a Norwegian archipelago in the Arctic Ocean, participated in 17 focus groups segregated by gender. A content analysis identified themes addressing the research questions. Participants described risk as being inherent to snowmobiling, and claimed that accidents followed from poor risk assessment, careless driving or mishaps. Evaluation of accidents and recommendations for preventive measures varied. Girls acknowledged the risks and wanted knowledge about outdoor life, navigation and external risks. Boys underestimated or downplayed the risks, and wanted knowledge about safety precautions while freeriding. Both genders were aware of how and why accidents occurred, and took precautions. Boys tended to challenge norms in ways that contradict the promotion of safe driving behaviour. Stories of internal justice regarding driving under the influence of alcohol occurred. Adolescents are aware of how accidents occur and how to avoid them. Injury prevention strategies should include a general population strategy and a high-risk strategy targeted at extreme risk-seekers. Drivers, snowmobilers' organisations and the community should share local knowledge in an effort to define problem areas, set priorities and develop and implement preventive measures. Risk prevention should include preparation of safe tracks and focus on safety equipment and safe driving behaviour, but should also pay increased attention to the potential of strengthening normative regulation within peer groups regarding driving behaviour and mutual responsibility for preventing accidents.

Manual materials handling: knowledge and practices among Portuguese health and safety practitioners.
Arezes, Pedro M; Miguel, A Sérgio; Colim, Ana S
2011-01-01
There are several methodologies to assess the risk involved in Manual Materials Handling (MMH). The aim of this study was to identify the knowledge and use of risk assessment methods among Portuguese Health and Safety (H&S) practitioners. The study involved the participation of 331 H&S practitioners and other related prevention professionals. An e-mail invitation to complete an online survey was sent to all Portuguese registered H&S practitioners. The previously developed and validated questionnaire included three different sections: (1) company characteristics; (2) description of types of MMH tasks performed; and (3) the respondents' use of and knowledge about risk assessment methods for MMH tasks. The answers obtained were collected from almost 350 companies. The characteristics of the companies showed that there is a predominance of external and internal H&S services for Small and Medium sized Enterprises (SMEs) and large companies, respectively. The NIOSH equation, Key Indicator Method (KIM) and Manual Assessment Chart (MAC) were identified as the most used and recognised risk assessment methods. Questionnaire results show that an important number of Portuguese H&S practitioners recognise some methods but have difficulty applying them correctly. Some practitioners reported that they had never used any type of risk assessment method.

In China, food safety problems have occurred frequently in the past ten years, causing great concern for the public. Adolescents, with higher exposure to problematic food, represent a unique target for interventions aimed at risk reduction. To understand their food safety knowledge, attitude and practice, a cross-sectional survey using paper questionnaire was carried out among 4,220 students (median age of 14 years, 50.3% females) from nine secondary schools in 3 districts of Beijing. The findings showed that the majority of respondents (42.0%) had a high knowledge level. Significant association was found between food safety knowledge score (median = 11, IQR:9–13) and demographic characteristics of region, school type, residence type, habit of smoking and alcohol use, academic record and parents’ education background. In terms of attitude and practice, only 17% of those surveyed regarded China’s food safety situation as good, 53.6% regarded it as worrying; almost all students (96.5%) did pay attention to food safety; 95.3% of the students had worried about the safety of the food provided by the small restaurants and street peddlers, but in reality, as many as 69.4% often or occasionally bought food from peddlers around their campuses and nearly half continued the consumption of such food in spite of worrying about its safety problems. Overall, the food safety knowledge among Beijing secondary school students was relatively good. They did not show much confidence in the country’s food safety situation, but many aware of the safety issues did not bother to change or take action. The study suggests that more systematic and targeted education on food safety is necessary for this age group. PMID:29095878

Background Reducing risk of HIV window period transmission requires understanding of donor knowledge and attitudes related to HIV and risk factors. Study Design and Methods We conducted a survey of 7635 presenting blood donors at three Brazilian blood centres from 15 October through 20 November 2009. Participants completed a questionnaire on HIV knowledge and attitudes about blood donation. Six questions about blood testing and HIV were evaluated using maximum likelihood chi-square and logistic regression. Test seeking was classified in non-overlapping categories according to answers to one direct and two indirect questions. Results Overall, respondents were male (64%) repeat donors (67%) between 18 and 49 years old (91%). Nearly 60% believed blood centres use better HIV tests than other places; however, 42% were unaware of the HIV window period. Approximately 50% believed it was appropriate to donate to be tested for HIV, but 67% said it was not acceptable to donate with risk factors even if blood is tested. Logistic regression found that less education, Hemope-Recife blood centre, replacement, potential and self-disclosed test-seeking were associated with less HIV knowledge. Conclusion HIV knowledge related to blood safety remains low among Brazilian blood donors. A subset finds it appropriate to be tested at blood centres and may be unaware of the HIV window period. These donations may impose a significant risk to the safety of the blood supply. Decreasing test-seeking and changing beliefs about the appropriateness of individuals with behavioural risk factors donating blood could reduce the risk of transfusing an infectious unit.

To describe the level of knowledge and perception of tuberculosis among public transport workers attending Road Safety Education courses in Lima, Peru. An observational, cross-sectional, analytic study was conducted between July and August 2014 in public transport workers attending the courses of Road Safety education. In Lima, such courses are mandatory for workers in the public transport area. An anonymous and voluntary survey was applied to obtain the following variables: sociodemographic characteristics, history of tuberculosis, tuberculosis knowledge and attitudes towards the disease. The factors associated to the risk perception of Tuberculosis infection were analysed using Poisson regression. From 309 attendees, 216 surveys were analysed (69.9%). Of these, 88.4% were males, 3.2% had a history of tuberculosis. The most widely known symptom was cough with phlegm (44.4%), the most popular source of information was television (39.8%), and only 9.7% had any training about tuberculosis. A 41.2% of respondents believed that working in the public transport sector was an occupation with a high risk of tuberculosis infection. No significant association between risk perception of tuberculosis and sociodemographic characteristics was found. A considerable lack of knowledge about tuberculosis symptoms and a low perception of risk for tuberculosis exists among public transport workers in Lima. Education strategies directed to this population need to be implemented.

Beyer, Anja; Westendorf, Christiane
The internet is a fast changing medium and comprises several websites fraught with risk. In this context especially young age groups are endangered. They have less experience using the media and little knowledge on existing internet risks. There are a number of initiatives, which are engaged in the topic of internet safety. They provide information about measures on how to prevent and to deal with internet risks. However it is not certain if these initiatives do reach their target group (children and adolescents). In this regard schools bear a special relevance, since they have the knowledge about didactic methods and the chance to address measures directly to children and adolescents. The authors of this paper provide an overview of current security education in German schools, problems and open questions. Finally the authors make recommendations on how to establish internet safety in schools.

Unintentional injuries are a leading cause of death and disability for children. Those with developmental disabilities, including children affected by prenatal alcohol exposure, are at highest risk for injuries. Although teaching safety skills is recommended to prevent injury, cognitive limitations and behavioral problems characteristic of children with fetal alcohol spectrum disorder make teaching these skills challenging for parents and teachers. In the current study, 32 children, ages 4-10, diagnosed with fetal alcohol syndrome (FAS) and partial FAS, learned fire and street safety through computer games that employed "virtual worlds" to teach recommended safety skills. Children were pretested on verbal knowledge of four safety elements for both fire and street safety conditions and then randomly assigned to one condition. After playing the game until mastery, children were retested verbally and asked to "generalize" their newly acquired skills in a behavioral context. They were retested after 1 week follow-up. Children showed significantly better knowledge of the game to which they were exposed, immediately and at follow-up, and the majority (72%) was able to generalize all four steps within a behavioral setting. Results suggested that this is a highly effective method for teaching safety skills to high-risk children who have learning difficulties.

This study aimed to investigate community pharmacists' knowledge and certainty of adverse effects and contraindications of pharmaceutical products to estimate the risk of error. Factors influencing their knowledge and certainty were also investigated. The knowledge of community pharmacists was assessed in a cross-sectional design using a multiple-choice questions test on the adverse effects and contraindications of active pharmaceutical ingredients and excipients from May 2014 to March 2015. Self-rated certainty scores were also recorded for each question. Knowledge and certainty scores were combined to estimate the risk of error. Out of 315 subjects, 129 community pharmacists (41.0%) completed the 30 multiple-choice questions test on active ingredients and excipients. Knowledge on active ingredients was associated with the year of graduation and obtaining a licence to practice pharmacy. Knowledge on excipients was associated with the degree obtained. There was higher risk of error in items on excipients than those on ingredients (P<0.01). The knowledge of community pharmacists in Palestine was insufficient with high risk of errors. Knowledge of community pharmacists on the safety issues of active ingredients and excipients need to be improved.

Having identified gaps in implementation of Rhode Island's syringe access law and police occupational safety education, public health and police professionals developed police training to boost legal knowledge, improve syringe access attitudes, and address needlestick injuries. Baseline data (94 officers) confirmed anxiety about needlestick injuries, poor legal knowledge, and occupational risk overestimation. Before training, respondents believed that syringe access promotes drug use (51%), increases likelihood of police needlestick injuries (58%), and fails to reduce epidemics (38%). Pretraining to posttraining evaluation suggested significant shifts in legal and occupational safety knowledge; changes in attitudes toward syringe access were promising. Training that combines occupational safety with syringe access content can help align law enforcement with public health goals. Additional research is needed to assess street-level effect and to inform intervention tailoring.
Sexual Safety Planning as an HIV Prevention Strategy for Survivors of Domestic Violence.

Victims of domestic violence (DV) are not only subject to physical and emotional abuse but may also be at increased risk for less recognized dangers from infection with human immunodeficiency virus (HIV) and other sexually transmitted pathogens. Because of the close link between DV and sexual risk, women need to be educated about the consequences of acquiring a life-threatening sexually transmitted infection, risk reduction measures, and how to access appropriate HIV services for diagnosis and treatment. It is therefore critical for DV workers to receive sufficient training about the link between DV and HIV risk so that sexual safety planning can be incorporated into activities with their clients in the same way as physical safety plans. In this article, we discuss how the Many Hands Working Together project provides interactive training for workers in DV and DV-affiliated agencies to increase their knowledge about HIV and teach sexual safety planning skills to achieve HIV risk reduction.

Studies on the widespread use of complementary and alternative medicine (CAM) demonstrate that CAM users base their treatment decisions on both subjective, experience-based knowledge and medical knowledge. The aim of this study was to explore lay and medical risk perceptions associated with CAM and conventional medicine. In this explorative qualitative study, we conducted in-depth interviews with 25 Norwegian CAM users with cancer or multiple sclerosis and 12 doctors. The interviews revealed fundamental differences in risk perceptions influencing treatment decisions and risk communication in a clinical setting. While CAM users considered conventional medicine as potentially risky and related this to experiences of severe adverse effects, CAM was perceived as natural and safe. Doctors' risk perceptions were quite the contrary, mainly because of lack of scientific evidence for CAM as a safe and beneficial treatment option. For the safety of CAM users, such divergent risk perceptions may have far-reaching consequences. CAM users should be taken seriously with their self-perception as decision-makers considering their approaches to experiences, knowledge, and science. An awareness of differing lay and medical risk perceptions associated with CAM and conventional medicine in research, doctor-patient communication, and education of patients and doctors is thus important to optimize patient safety in complex health care systems. © 2015 S.

The EU Directive 2004/40/EC on the minimum health and safety requirements regarding the exposure of workers to the risks arising from physical agents (electromagnetic fields) will introduce the need of an evaluation of the risk related to EMF occupational exposure in pregnancy. Nevertheless, data from research in this field are scarcely conclusive to date. Furthermore knowledge on this risk seems insufficient among OH physicians in Italy. Accordingly, there is an urgent need for further research, and for a diffusion of knowledge among OH physicians on possible risk to pregnancy due to occupational exposure to EMF.

Limited data are available on interventions to reduce sexual risk behaviors and increase knowledge of HIV vaccine trial concepts in high-risk populations eligible to participate in HIV vaccine efficacy trials. The UNITY Study was a 2-arm randomized trial to determine the efficacy of enhanced HIV risk-reduction and vaccine trial education interventions to reduce the occurrence of unprotected vaginal sex acts and increase HIV vaccine trial knowledge among 311 HIV-negative noninjection drug using women. The enhanced vaccine education intervention using pictures along with application vignettes and enhanced risk-reduction counseling consisting of 3 one-on-one counseling sessions were compared with standard conditions. Follow-up visits at 1 week and 1, 6, and 12 months after randomization included HIV testing and assessment of outcomes. During follow-up, the percent of women reporting sexual risk behaviors declined significantly but did not differ significantly by study arm. Knowledge of HIV vaccine trial concepts significantly increased but did not significantly differ by study arm. Concepts about HIV vaccine trials not adequately addressed by either condition included those related to testing a vaccine for both efficacy and safety, guarantees about participation in future vaccine trials, assurances of safety, medical care, and assumptions about any protective effect of a test vaccine. Further research is needed to boost educational efforts and strengthen risk-reduction counseling among high-risk noninjection drug using women.

Surgeons routinely work in an environment with occupational risks and hazards about which they are often uninformed. Based on the currently available scientific literature this review article describes the various hazards in the operating theater and their effects on personnel, particularly from the surgical perspective. A further aim of this article is to describe the occupational safety measures to reduce the burdens and to maintain the long-term health of personnel. Ultimately, surgeons should be equipped with the necessary knowledge for implementing hazard assessments according to the German Occupational Health and Safety Act. Surgeons are exposed to increased risks and hazards by working in awkward positions with a high risk for musculoskeletal pain and injuries. They are also commonly exposed to inhalational anesthetics, surgical smoke, radiation, noise and infectious agents. Furthermore, the mental and emotional stress associated with these activities is also high. Meaningful occupational safety measures for reduction of burdens are from a technical aspect the installation of effective air extraction systems, measures to reduce exposure to radiation and noise and the use of safer instruments to prevent needle stick injuries. Furthermore, individual occupational safety measures, such as the use of personal protective equipment (e.g. radiation protective clothing and double gloves) must be observed. The consistent implementation and also adherence to these described occupational safety measures and regulations can reduce the burden on operating theater personnel and contribute to maintaining health. Furthermore, periodic preventive healthcare controls and health checks by the company medical officer and individually initiated additional prevention measures can be a sensible augmentation to these safety measures.
Stakeholder Perceptions of Risk in Construction.
Zhao, Dong; McCoy, Andrew P; Kleiner, Brian M; Mills, Thomas H; Lingard, Helen
2016-02-01
Safety management in construction is an integral effort and its success requires inputs from all stakeholders across design and construction phases. Effective risk mitigation relies on the concordance of all stakeholders' risk perceptions. Many researchers have noticed the discordance of risk perceptions among critical stakeholders in safe construction work, however few have provided quantifiable evidence describing them. In an effort to fill this perception gap, this research performs an experiment that investigates stakeholder perceptions of risk in construction. Data analysis confirms the existence of such discordance, and indicates a trend in risk likelihood estimation. With risk perceptions from low to high, the stakeholders are architects, contractors/safety professionals, and engineers. Including prior studies, results also suggest that designers have improved their knowledge in building construction safety, but compared to builders they present more difficultly in reaching a consensus of perception. Findings of this research are intended to be used by risk management and decision makers to reassess stakeholders' varying judgments when considering injury prevention and hazard assessment.

Many unintentional injuries to young children occur in the home. The current study examines the relation between family socioeconomic and sociodemographic factors and risk factors for home injury. Presence of household hazards was examined in 80 families with toddler-aged children. Parental ability to identify household hazards in pictures was also assessed. ANOVAs and Pearson product-moment correlations examined the relationship between presence of household hazards, knowledge to identify hazards, and factors of yearly family income, parental age, parental education, parental marital status, child ethnicity, and the number of children living in the home. A greater number of hazards were found in the homes of both the lowest and highest income families, but poorer knowledge to identify household hazards was found only among parents of the lowest income families and younger parents. Across family socioeconomic status, parent knowledge of hazards was related to observed household hazards. The relationship between family income and risk for injury is complex, and children of both lower and higher SES families may be at risk for injury. While historically particular focus has been placed on risk for injury among children in low income families, injury prevention efforts should target reducing presence of household hazards in both high and low SES families.

Because nursing is a high risk profession in terms of occupational health and safety (OHS), the topic of OHS is an important component of student nurse education and practice. Seeking ways to enhance curricular content and foster student health, safety and wellbeing is an ongoing pursuit. This pilot study explored nursing student perspectives about OHS in the clinical setting to develop an understanding of student views that could enlighten teaching about this topic within the undergraduate nursing course. Focus groups were held with pre-registration student nurses in two discrete cohort levels (first and third year). Themes were identified from the focus group discussion about trust, knowledge and responsibility. The students demonstrated a sound grasp of clinical hazards and associated administrative controls. Strengthening student awareness of higher order controls and their evaluation would augment their knowledge of legislative requirements. Students may benefit from learning about a risk management approach to OHS which would provide them with a structured basis for problem solving. This may assist them with clinical reasoning about health and safety issues and empower them in aspects of self-care. Copyright © 2016 Elsevier Ltd. All rights reserved.

To assess the knowledge and attitude of medical students towards road safety and to determine their driving behavior and its relation to different related factors. This cross-sectional study involved 480 medical students at Mansoura University, Egypt. A self-administered questionnaire was used to collect student personal data, knowledge about road safety, attitude towards road safety, and driving practices. More than 40% of students experienced an injury in the previous year, mainly as a pedestrian (56%), and 15.2% practiced driving, although only 9.6% had a driving licence. Most of the students had correct road safety knowledge except for awareness that the safe time to read maps is when your vehicle is parked (44%), one should drive in the left lane (29.6%), and one should overtake from the right-hand lane only (25.8%). The majority of the students reported that road traffic injuries can be prevented (89.2%). The mean score of the driving practices of the students ranged from 0.66±1.04 to 2.44±6.28 and rural residents showed significantly higher score regarding errors and lapses. Good road safety knowledge and a favorable, low risk attitude, did not translate into improved road traffic behavior and this highlights the importance of stricter implementation of the existing rules and including road safety in medical education programs.

The US Food and Drug Administration uses drug safety communications (DSCs) to release emerging information regarding post-market safety issues, but it is unclear the extent of awareness by patients and providers of these communications and their specific recommendations. We conducted semi-structured interviews with patients and physicians to evaluate their awareness and understanding of emerging drug safety information related to two sleep aids: zolpidem or eszopiclone. We conducted interviews with 40 patients and ten physicians recruited from a combination of insurer claims databases and online sources. We evaluated (1) sources of drug safety information; (2) discussions between patients and physicians about the two medications; (3) their knowledge of the DSC; and (4) preferences for learning about future drug safety information. Interviews were transcribed and analyzed thematically. Patients cited their physicians, pharmacy inserts, and the Internet as sources of drug safety information. Physicians often referred to medical journals and online medical sources. Most patients reported being aware of information contained in the DSC summaries they were read. Almost all patients and physicians reported discussing side effects during patient-provider conversations, but almost no patients mentioned that physicians had communicated with them key messaging from the DSCs at issue: the risk of next-morning impairment with zolpidem and the lower recommended initial dose for women. Some risks of medications are effectively communicated to patients and physicians; however, there is still a noticeable gap between information issued by the Food and Drug Administration and patient and physician awareness of this knowledge, as well as patients' decisions to act on this information. Disseminators of emerging drug safety information should explore ways of providing user-friendly resources to patients and healthcare professionals that can update them on new risks in a timely manner.

Due to the knowledge gap that exists between patients and health care staff the quality of medical treatment usually cannot be assessed securely by patients. For an optimization of safety in treatment-related processes of medical care, the medical staff needs to be actively involved in preventive and proactive quality management. Using voluntary, confidential and non-punitive systematic employee surveys, vulnerable topics and areas in patient care revealing preventable risks can be identified at an early stage. Preventive measures to continuously optimize treatment quality can be defined by creating a risk portfolio and a priority list of vulnerable topics. Whereas critical incident reporting systems are suitable for continuous risk assessment by detecting safety-relevant single events, employee surveys permit to conduct a systematic risk analysis of all treatment-related processes of patient care at any given point in time.

Having identified gaps in implementation of Rhode Island's syringe access law and police occupational safety education, public health and police professionals developed police training to boost legal knowledge, improve syringe access attitudes, and address needlestick injuries. Baseline data (94 officers) confirmed anxiety about needlestick injuries, poor legal knowledge, and occupational risk overestimation. Before training, respondents believed that syringe access promotes drug use (51%), increases likelihood of police needlestick injuries (58%), and fails to reduce epidemics (38%). Pretraining to posttraining evaluation suggested significant shifts in legal and occupational safety knowledge; changes in attitudes toward syringe access were promising. Training that combines occupational safety with syringe access content can help align law enforcement with public health goals. Additional research is needed to assess street-level effect and to inform intervention tailoring. PMID:21940924

College students are one of the most at-risk population groups for food poisoning, due to risky food safety behaviors. Using the Likert Scale, undergraduate students were asked to participate in a Food Safety Survey which was completed by 499 students ages 18-25. Data was analyzed using SPSS and AMOS statistical software. Four conceptual definitions regarding food safety were defined as: general food safety, bacterial food safety, produce food safety, and politics associated with food safety. Knowledge seems to be an important factor in shaping students attitudes regarding general and bacterial safety. Ethnicity plays a role in how people view the politics of food safety, and the safety of organic foods.

Magnetic Resonance Imaging (MRI) has a superior soft-tissue contrast compared to other radiological imaging modalities and its physiological and functional applications have led to a significant increase in MRI scans worldwide. A comprehensive MRI safety training to protect patients and other healthcare workers from potential bio-effects and risks of the magnetic fields in an MRI suite is therefore essential. The knowledge of the purpose of safety zones in an MRI suite as well as MRI appropriateness criteria is important for all healthcare professionals who will work in the MRI environment or refer patients for MRI scans. The purpose of this article is to give an overview of current magnetic resonance safety guidelines and discuss the safety risks of magnetic fields in an MRI suite including forces and torque of ferromagnetic objects, tissue heating, peripheral nerve stimulation and hearing damages. MRI safety and compatibility of implanted devices, MRI scans during pregnancy and the potential risks of MRI contrast agents will also be discussed and a comprehensive MRI safety training to avoid fatal accidents in an MRI suite will be presented.

Farmers' markets are increasingly popular venues in North America for the sale of fresh produce and other foods. However, the nature of their operation can present possible food safety issues, challenges, and risks to consumers. A knowledge synthesis was conducted to identify, characterize, and summarize published research on the microbial food safety issues and implications associated with farmers' markets. A scoping review was conducted using the following steps: comprehensive search strategy, relevance screening of abstracts, and characterization of relevant articles. Two subsets of data were prioritized for more detailed systematic review (data extraction and risk-of-bias assessment) and meta-analysis: (i) studies comparing the microbial safety of foods from farmers' markets versus other sources and (ii) studies evaluating the use of food safety practices at farmers' markets. Overall, 83 relevant studies were identified. The majority of studies were published as journal articles (64%), used a cross-sectional design (81%), and were conducted in the United States (78%). Most studies (39%; n = 32) investigated stakeholder, mostly consumer (n = 22), attitudes toward food safety at farmers' markets. Limited but heterogeneous evidence indicated a higher prevalence of Campylobacter and Salmonella in chicken meat from farmers' markets versus other retail sources, but there was no difference in the microbial contamination of fresh produce. Studies evaluating the use of food safety practices at farmers' markets identified some gaps; for example, the average prevalence of vendor hand washing was 4% (95% confidence interval: 0 to 11%; I 2 = 27%; n = 5 studies). Twelve foodborne outbreaks and case reports were identified, resulting in a total of 411 illnesses, 38 hospitalizations, and two deaths from 1994 to 2016. Only five intervention studies were identified. Key knowledge gaps and areas warranting future research, training, and education are highlighted and discussed.

Tractor rollovers continue to be one of the most frequent causes of agricultural fatalities. Despite knowledge of rollovers and the efficacy of rollover protective structures (ROPS), few New York farmers have considered installing ROPS on their unprotected tractors. Qualitative interviews conducted with an "at-risk" segment of the New York farming community indicate that there are a number of barriers to safety in general and to retrofitting, in particular. The following themes and categories emerged in relation to safety and risk taking: constant exposures to risk with positive outcomes normalizes risk; the modeling of risk by significant others positions risk as part of a farming identity; and the pressure to reduce costs, save time, and accept risk frames risk-taking as the cost-effective option (especially in regard to retrofitting, which farmers believe is both expensive and time-consuming). Recommendations for researchers planning retrofitting interventions would be to focus safety messages on the risk to significant others or on the financial impact of rollovers, and to provide financial incentives and assistance to farmers considering retrofitting.

The premise of this comment perpetuates an unfortunate trend among some radiation researchers to minimize potential risks to human tissue from low-radiation sources. In fact, this discussion on the risk uncertainties of low-dose radiation further illustrates the need for more measurements and a program of active monitoring, especially when solar eruptive events can substantially elevate the radiation environment. This debate also highlights the context of a bigger problem; i.e., how do we as professionals act with due diligence to take the immense body of knowledge of space weather radiation effects on human tissue and distil it into ideas that regulatory agencies can use to maximize the safety of a population at risk. The focus of our article on radiation risks due to solar energetic particle events starts with our best assessment of risks and is based on the body of scientific knowledge while, at the same time, erring on the side of public safety. The uncertainty inherent in our assessment is accepted and described with this same philosophy in mind.
Traffic crash involvement: experiential driving knowledge and stressful contextual antecedents.
Legree, Peter J; Heffner, Tonia S; Psotka, Joseph; Martin, Daniel E; Medsker, Gina J
2003-02-01
Researchers have rarely examined stressful environments and psychological characteristics as predictors of driving behavior in the same study. The authors hypothesized that (a) safer drivers more accurately assess physical and emotional traffic hazards and (b) stress and emotional states elevate crash risk. The hypotheses were evaluated with procedural and declarative tacit driving knowledge tests requiring assessment of emotional and contextual hazards and with accident reports describing crash antecedents, including stressful events and environmental conditions. Analyses identified separate driving knowledge factors corresponding to emotional and contextual hazards that were significantly related to the crash criteria. Accident report analyses show that stress significantly elevates at-fault crash risk. The results demonstrate the importance of experiential knowledge acquired without instruction (procedural or tacit knowledge) and provide safety recommendations.

Knowledge and lessons from past accidental exposures in radiotherapy are very helpful in finding safety provisions to prevent recurrence. Disseminating lessons is necessary but not sufficient. There may be additional latent risks for other accidental exposures, which have not been reported or have not occurred, but are possible and may occur in the future if not identified, analyzed, and prevented by safety provisions. Proactive methods are available for anticipating and quantifying risk from potential event sequences. In this work, proactive methods, successfully used in industry, have been adapted and used in radiotherapy. Risk matrix is a tool that can be used in individual hospitals to classify event sequences in levels of risk. As with any anticipative method, the risk matrix involves a systematic search for potential risks; that is, any situation that can cause an accidental exposure. The method contributes new insights: The application of the risk matrix approach has identified that another group of less catastrophic but still severe single-patient events may have a higher probability, resulting in higher risk. The use of the risk matrix approach for safety assessment in individual hospitals would provide an opportunity for self-evaluation and managing the safety measures that are most suitable to the hospital's own conditions.

The recent growth in smokeless tobacco (ST) consumption has raised questions about consumer risk perceptions of ST products, especially in high-risk vulnerable populations. This qualitative study examined risk perceptions of ST among adolescent and adult users and non-users in Ohio Appalachia. Focus groups and interviews were held with adolescents (n=53; mean age of 17 years) and adults (n=63; mean age of 34 years) from four Ohio Appalachian counties. Participants were asked about their perceptions of ST-related health risks, ST safety, and the relative safety of ST compared to cigarettes. Transcriptions were coded independently by two individuals. Overall, participants were knowledgeable about health problems from ST use (e.g., oral cancers, periodontal disease). Nearly all participants stated that ST use is not safe; however, there was disagreement about its relative safety. Some perceived all tobacco products as equally harmful; others believed that ST is safer than cigarettes for either the user or those around the user. Disagreements about ST relative safety may reflect mixed public health messages concerning the safety of ST. Comprehensive consumer messages about the relative safety of ST compared to cigarettes are needed. Messages should address the effect of ST on the health of the user as well as those exposed to the user. PMID:25832126

The Technology Safety Project of the Washington State Coalition Against Domestic Violence was designed to increase awareness and knowledge of technology safety issues for domestic violence victims, survivors, and advocacy staff. The project used a "train-the-trainer" model and provided computer and Internet resources to domestic violence service providers to (a) increase safe computer and Internet access for domestic violence survivors in Washington, (b) reduce the risk posed by abusers by educating survivors about technology safety and privacy, and (c) increase the ability of survivors to help themselves and their children through information technology. Evaluation of the project suggests that the program is needed, useful, and effective. Consumer satisfaction was high, and there was perceived improvement in computer confidence and knowledge of computer safety. Areas for future program development and further research are discussed.
Motorcyclists' perceptions and experiences of riding and risk and their advice for safety.

To examine the knowledge, observations, and perceptions of motorcycle riders on the risks of on-road motorcycling and potential safety measures to give insight and guidance in developing policies, programs, and legislation to improve the safety of motorcyclists. Individual and focus group interviews were conducted with dealers and a cross section of motorcyclists from selected regions across New Zealand. The interviews were analyzed and coded to identify common themes and diverse perspectives on why people rode motorcycles, riders' perceptions on risk, and possible safety strategies for on-road motorcycling. Motorcycling has major benefits for riders, although most riders perceived that the risks could be severe and they were susceptible to injury. Their observations on the threats and barriers to safety focused on 3 components: the rider, the motorcycle, and the environment. Risks included inexperience, not riding to the conditions, choice of motorcycle, protective clothing and conspicuity, and speed. The underlying risk of being on 2 wheels was accentuated by the availability of high-power motorcycles. The threats perceived in the environment included the behavior of other road users, especially car drivers, and the poor road conditions and surrounds encountered. Riders identified risks that have been recognized in the road safety literature as well as risks for which there are no engineering or scientific solutions. To effectively increase motorcyclist safety, recognition of the commonalities and the differences between motorcyclists' perspectives and proposed strategies is needed. This approach is more likely to engage riders and thus support positive behavior change among riders and drivers.

Occupational health in a changing world has to face up to psychosocial risks to protect the health of employees now and in the future. Faster production, service and communication processes, a service- and knowledge-based society, an increasing proportion of intellectual work, growing complexity of work-related demands, new technologies and constant availability, mobility demands, and job insecurity contribute to the problem of psychosocial risks in the workplace. Psychosocial risks affect both physical and psychosocial health. There is scientific evidence of the link between psychosocial work-related stress and cardiovascular diseases, affective disorders or musculoskeletal disorders, especially chronic back pain.The Framework Directive on Safety and Health makes it very clear that employers are obliged "to ensure the safety and health of workers in every aspect relating to work". In spite of these far reaching obligations, a kind of taboo sometimes makes it hard to focus on topics that have psychosocial implications. A large number of models, instruments and methods are now available to gauge psychosocial risks in the workplace. Given the clear contrast between knowledge and application, there is not a lack of knowledge in this regard, but rather a lack of application.In Germany, statutory accident insurance institutions are guided by two key principles: putting prevention before rehabilitation and rehabilitation before compensation. To prevent work-related health risks the BG RCI has developed several prevention tools to help employers and employees deal with psychosocial risks in the workplace.

Work, a defining feature of adolescence in the United States, has many benefits. Work also has risks, as adolescents experience a higher rate of serious job-related injuries compared to adults. Talking Safety, a free curriculum from the National Institute for Occupational Safety and Health, is one tool educators may adopt to provide teens with essential workplace safety and health education. Adolescents (N = 2503; female, 50.1%; Hispanic, 50.0%) in a large urban school district received Talking Safety from their eighth-grade science teachers. This study used a modified theory of planned behavior (which included a knowledge construct), to examine students' pre- and post-intervention scores on workplace safety and health knowledge, attitude, self-efficacy, and behavioral intention to enact job safety skills. The results from confirmatory factor analyses indicate three unique dimensions reflecting the theory, with a separate knowledge factor. Reliability estimates are ω ≥ .83. The findings from the structural equation models demonstrate that all paths, except pre- to posttest behavioral intention, are statistically significant. Self-efficacy is the largest contributor to the total effect of these associations. As hypothesized, knowledge has indirect effects on behavioral intention. Hispanic students scored lower at posttest on all but the behavioral intention measure, possibly suggesting the need for tailored materials to reach some teens. Overall the findings support the use of a modified theory of planned behavior to evaluate the effectiveness of a foundational workplace safety and health curriculum. This study may inform future efforts to ensure that safe and healthy work becomes integral to the adolescent experience.

Driving speed is an important traffic safety issue. The lack of adherence to posted speed limits is a safety concern, especially on university campuses where the populations of drivers are at increased risk for crashes involving speeding due to their young age. Thus, driver speed and knowledge of speed limits on university campuses is an important…

The safety of diagnostic imaging during pregnancy is an important aspect for all clinicians. Pregnant women often do not receive proper dental care as the dentists are not aware of low diagnostic radiation doses involved in dental radiation. To assess awareness of radiation risks on pregnant women among dentists of Ghaziabad city. A total of 268 practicing dentists in Ghaziabad were selected for a questionnaire based cross-sectional study. Data consisted of 18 questions which assessed the knowledge, attitude and practice of dental professionals regarding radiation risks on pregnant women. The questionnaire was distributed and collected personally by the principal investigator. Data was analyzed by Mann Whitney U test and chi-square test. The level of significance was set at p ≤ 0.05. The results showed that the dentists who had attended continuing dental education program had increased level of knowledge regarding radiation effects among pregnant women as compared to the dentists who had not attended continuing dental education programs (p<0.05). Among them who had attended continuing dental education programs 93.3% were aware of the safe dose of radiation and 62% were aware of threshold radiation doses of pregnancy termination. On the contrary there was no significant difference in the knowledge, attitude and practice scores regarding radiation risks on pregnant women based on their academic qualification (p≥0.05). The level of knowledge among dentists was found to be satisfactory, this outcome shows that continuing dental education regarding radiation protection principles and its risks on pregnant women is required to ensure maximum safety both for clinician as well as pregnant women.

Background Limited data are available on interventions to reduce sexual risk behaviors and increase knowledge of HIV vaccine trial concepts in high risk populations eligible to participate in HIV vaccine efficacy trials. Methods The UNITY Study was a two-arm randomized trial to determine the efficacy of enhanced HIV risk reduction and vaccine trial education interventions to reduce the occurrence of unprotected vaginal sex acts and increase HIV vaccine trial knowledge among 311 HIV-negative non-injection drug using women. The enhanced vaccine education intervention using pictures along with application vignettes and enhanced risk reduction counseling consisting of three one-on-one counseling sessions were compared to standard conditions. Follow-up visits at one week and one, six and twelve months after randomization included HIV testing and assessment of outcomes. Results During follow up, the percent of women reporting sexual risk behaviors declined significantly, but did not differ significantly by study arm. Knowledge of HIV vaccine trial concepts significantly increased but did not significantly differ by study arm. Concepts about HIV vaccine trials not adequately addressed by either condition included those related to testing a vaccine for both efficacy and safety, guarantees about participation in future vaccine trials, assurances of safety, medical care, and assumptions about any protective effect of a test vaccine. Conclusions Further research is needed to boost educational efforts and strengthen risk reduction counseling among high-risk non-injection drug using women. PMID:20190585
Traffic behaviour among adolescents using mopeds and light motorcycles.
Njå, Ove; Nesvåg, Sverre M
2007-01-01
Motorcycling is recognized to be a relatively risky activity. Powered two wheelers (PTW) are classified as mopeds, light, and heavy motorcycles, the first two categories being denoted light PTWs. This paper reviews the scientific literature on accident risks and traffic behavior among users of light PTWs with the aim of clarifying the current state of knowledge. Based on a risk analytical and an anthropological perspective on motorcycling, the paper discusses the significance of cultural and social factors as important aspects of safety. More targeted and effective safety measures, for example better training programs, are needed to prevent motorcycle accidents. This means developing a deeper understanding of the rider as an individual, and the individuals within different groups and settings. Why and how motorcyclists approach the road, its function as a social arena, the varieties of goals and values, and the motorcyclists' own perceptions of the behavior that ensures their "achievements" or "successes", are some of the issues. Today, this kind of knowledge is scarce and almost entirely absent from the scientific literature. We conclude that the massive quantities of data on numbers of accidents, the categorization of situations, the causal explanations related to speed, gender, age, lack of concentration so forth, can only be employed as support for safety measures as long as they are linked to social and cultural factors. Risk informed decision making has become an integral part of authorities' and manufacturers' implementation of safety measures. This tendency is strengthened by the fact that the responsibility of product safety rests upon the manufacturers, cf. for example EU safety regulations. Therefore it is paramount that a thorough understanding of social and cultural factors related to the PTW driving is necessary for the industry to develop targeted and efficient safety measures.
Children's views of accident risks and prevention: a qualitative study
Green, J.; Hart, L.
1998-01-01
Objectives—To examine children's accounts of injury risks and opportunities for prevention. Setting—Schools, youth clubs, and a holiday activity scheme in the south east of England. Methods—Sixteen focus groups were held with 7–11 year old children. Transcripts of the discussions were analysed using qualitative methods. Results—Children were knowledgeable about injury risks and how to reduce them. They also saw injury prevention as primarily their own responsibility. However, they were also sophisticated in their criticisms of generalised prevention advice, and evaluated safety messages in the light of local environmental and social knowledge. Personal experience was more often reported as a reason for risk reduction than formal prevention advice. Risks for injury were not isolated from other risks faced. Conclusions—Effective educational interventions aimed at changing children's risk behaviour should build more on children's own competence and knowledge of their local environment, and stress the need to manage risks rather than avoid dangers.

Skin cancer is the most common cancer in the USA and is increasing in children and young adults. Adolescents are an important target population for sun-safety interventions with ultraviolet radiation as the strongest risk factor for developing skin cancer. Schools are an ideal setting to intervene with adolescents. A novel Arizona skin cancer prevention in-class education-activity program, Project 'Students are Sun Safe' (SASS), was designed to be delivered by university students for middle school and high school students. Participant students completed the pre- and post-program tests and a satisfaction questionnaire; teachers completed reviews. The evaluation examined the program's influence on participants' sun-safety knowledge, perceptions, and behaviors; satisfaction with the program; and intent to change. After exposure to Project SASS, participants were more likely to perceive a high risk of skin cancer, report negative attitudes toward tanned skin, and answer knowledge-based questions correctly. There were minimal differences in self-reported sun-safety behaviors, though participants did report intent to change. Both participants and teachers were satisfied with the program. Project SASS appears to be an effective sun-safety program for middle school and high school students for knowledge and perceptions, and the results confirm that appropriately tailoring program components to the target population has strong potential to impact adolescent perceived susceptibility, knowledge, and behavioral intent. The strengths and weaknesses of Project SASS have many implications for public health practice, and Project SASS may hold promise to be a model for skin cancer prevention in adolescents.
Pesticide use knowledge and practices: A gender differences in Nepal
DOE Office of Scientific and Technical Information (OSTI.GOV)
Atreya, Kishor
It is important to understand gender difference on pesticide use knowledge, attitude and practices for identifying pesticide risks by gender and to recommend more gender-sensitive programs. However, very few studies have been conducted so far in Nepal. This study, thus, interviewed a total of 325 males and 109 females during 2005 to assess gender differences on pesticide use knowledge, attitude and practices. More than 50% females had never been to school and only <8% individuals were found trained in Integrated Pest Management (IPM). Almost all males and females did not smoke, drink and eat during pesticides application and also believedmore » that pesticides are harmful to human health, livestock, plant diversity and their environment. However, there were gender differences on household decision on pesticides to be used (p<0.001), care of wind direction during spraying (p=0.032), prior knowledge on safety measures (p=0.016), reading and understanding of pesticides labels (p<0.001), awareness of the labels (p<0.001) and protective covers. Almost all respondents were aware of negative impacts of pesticide use on human health and environment irrespective of gender; however, females were at higher risk due to lower level of pesticide use safety and awareness. It is strongly recommended to initiate gender-sensitive educational and awareness activities, especially on pesticide use practices and safety precautions.« less

The objective of this study was to design and develop food safety knowledge and attitude scales based on food-handling guidelines developed by a national panel of food safety experts. Knowledge (n=43) and attitude (n=49) questions were developed and pilot-tested with a variety of consumer groups. Final questions were selected based on item analysis and on validity and reliability statistical tests. Knowledge questions were tested in Washington State with participants in low-income nutrition education programs (pretest/posttest n=58, test/retest n=19) and college students (pretest/posttest n=34). Attitude questions were tested in Ohio with nutrition education program participants (n=30) and college students (non-nutrition majors n=138, nutrition majors n=57). Item analysis, paired sample t tests, Pearson's correlation coefficients, and Cronbach's alpha were used. Reliability and validity tests of individual items and the question sets were used to reduce the scales to 18 knowledge questions and 10 attitude questions. The knowledge and attitude scales covered topics ranked as important by a national panel of experts and met most validity and reliability standards. The 18-item knowledge questionnaire had instructional sensitivity (mean score increase of more than three points after instruction), internal reliability (Cronbach's alpha >.75), and produced similar results in test-retest without intervention (coefficient of stability=.81). Knowledge of correct procedures for hand washing and avoiding cross-contamination was widespread before instruction. Knowledge was limited regarding avoiding food preparation while ill, cooking hamburgers, high-risk foods, and whether cooked rice and potatoes could be stored at room temperature. The 10-item attitude scale had an appropriate range of responses (item difficulty) and produced similar results in test-retest ( P =.01). Internal consistency ranged from alpha=.63 to .89. Students anticipating a career where food safety is valued had higher attitude scale scores than participants of extension education programs. Uses for the knowledge questionnaire include assessment of subject matter knowledge before instruction and knowledge gain after instruction. The attitude scale assesses an outcome variable that may predict food safety behavior.

College students are one of the most at-risk population groups for food poisoning, due to risky food safety behaviors. Using the Likert Scale, undergraduate students were asked to participate in a Food Safety Survey which was completed by 499 students ages 18–25. Data was analyzed using SPSS and AMOS statistical software. Four conceptual definitions regarding food safety were defined as: general food safety, bacterial food safety, produce food safety, and politics associated with food safety. Knowledge seems to be an important factor in shaping students attitudes regarding general and bacterial safety. Ethnicity plays a role in how people view the politics of food safety, and the safety of organic foods. PMID:23364131

mHealth and Mobile Medical Apps: A Framework to Assess Risk and Promote Safer Use
2014-01-01
The use of mobile medical apps by clinicians and others has grown considerably since the introduction of mobile phones. Medical apps offer clinicians the ability to access medical knowledge and patient data at the point of care, but several studies have highlighted apps that could compromise patient safety and are potentially dangerous. This article identifies a range of different kinds of risks that medical apps can contribute to and important contextual variables that can modify these risks. We have also developed a simple generic risk framework that app users, developers, and other stakeholders can use to assess the likely risks posed by a specific app in a specific context. This should help app commissioners, developers, and users to manage risks and improve patient safety. PMID:25223398

The safety effects of cooperative intelligent transport systems (C-ITS) are mostly unknown and associated with uncertainties, because these systems represent emerging technology. This study proposes a bowtie analysis as a conceptual framework for evaluating the safety effect of cooperative intelligent transport systems. These seek to prevent road traffic accidents or mitigate their consequences. Under the assumption of the potential occurrence of a particular single vehicle accident, three case studies demonstrate the application of the bowtie analysis approach in road traffic safety. The approach utilizes exemplary expert estimates and knowledge from literature on the probability of the occurrence of accident risk factors and of the success of safety measures. Fuzzy set theory is applied to handle uncertainty in expert knowledge. Based on this approach, a useful tool is developed to estimate the effects of safety-related cooperative intelligent transport systems in terms of the expected change in accident occurrence and consequence probability.

How to make the most of failure mode and effect analysis.
Stalhandske, Erik; DeRosier, Joseph; Patail, Bryanne; Gosbee, John
2003-01-01
Current accreditation standards issued by the Joint Commission for the Accreditation of Healthcare Organizations (JCAHO) require hospitals to carry out a proactive risk assessment on at least 1 high-risk activity each year for each accredited program. Because hospital risk managers and patient safety managers generally do not have the knowledge or level of comfort for conducting a proactive risk assessment, they will appreciate the expertise offered by biomedical equipment technicians (BMETs), occupational safety and health professionals, and others. The skills that have been developed by BMETs and others while conducting job safety analyses or failure mode effect analysis can now be applied to a health care proactive analysis. This article touches on the Health Care Failure Mode and Effect Analysis (HFMEA) model that the Department of Veterans Affairs (VA) National Center for Patient Safety developed for proactive risk assessment within the health care community. The goal of this article is to enlighten BMETs and others on the growth of proactive risk assessment within health care and also on the support documents and materials produced by the VA. For additional information on HFMEA, visit the VA website at www.patientsafety.gov/HFMEA.html.
Sensemaking of patient safety risks and hazards.
Battles, James B; Dixon, Nancy M; Borotkanics, Robert J; Rabin-Fastmen, Barbara; Kaplan, Harold S
2006-08-01
In order for organizations to become learning organizations, they must make sense of their environment and learn from safety events. Sensemaking, as described by Weick (1995), literally means making sense of events. The ultimate goal of sensemaking is to build the understanding that can inform and direct actions to eliminate risk and hazards that are a threat to patient safety. True sensemaking in patient safety must use both retrospective and prospective approach to learning. Sensemaking is as an essential part of the design process leading to risk informed design. Sensemaking serves as a conceptual framework to bring together well established approaches to assessment of risk and hazards: (1) at the single event level using root cause analysis (RCA), (2) at the processes level using failure modes effects analysis (FMEA) and (3) at the system level using probabilistic risk assessment (PRA). The results of these separate or combined approaches are most effective when end users in conversation-based meetings add their expertise and knowledge to the data produced by the RCA, FMEA, and/or PRA in order to make sense of the risks and hazards. Without ownership engendered by such conversations, the possibility of effective action to eliminate or minimize them is greatly reduced.

Pedestrian injuries are a leading cause of death among South African children, and young children residing in low-income communities are more at risk, due to various factors such as inadequate road infrastructure, exposure to traffic due to reliance on walking as a means of transport, and lack of supervision. This study used a cross-sectional, non-randomized self-report survey to assess pedestrian safety knowledge, road-crossing behaviour and pedestrian injuries of primary school children in selected low-income settings in Cape Town. The survey focused on three primary schools that had joined the Safe Kids Worldwide Model School Zone Project and was administered to 536 children aged 6-15 years, in their home language of isiXhosa. Descriptive and bivariate analyses as well as multivariate regression analyses were conducted to investigate potential predictor variables for pedestrian collision severity and unsafe road-crossing behaviour. Walking was the sole form of travel for 81% of the children, with a large proportion regularly walking unsupervised. Children who walk to or from school alone were younger and reported riskier road-crossing behaviour, although children who walk accompanied tended to have higher pedestrian collision severity. "Negligent Behaviour" related to road-crossing was significantly associated with higher pedestrian collision severity, with predictors of "Negligent Behaviour" including the lack of pedestrian safety knowledge and greater exposure to traffic in terms of time spent walking. More than half of the reported pedestrian collisions involved a bicycle, and older boys (10-15 years) were most at risk of experiencing a severe pedestrian injury. The findings substantiate emerging evidence that children in low-income settings are at greater risk for child pedestrian injury, and emphasise the need for evidence-based safety promotion and injury prevention interventions in these settings.

The workplace is a key setting where gender issues and organizational structures may influence occupational health and safety practices. The enactment of dominant norms of masculinity in high risk occupations can be particularly problematic, as it exposes men to significant risks for injuries and fatalities. To encourage multi-disciplinary collaborations and advance knowledge in the intersecting areas of gender studies, men’s health, work and workplace health and safety, a national network of thirteen researchers and health and safety stakeholders completed a critical literature review examining the intersection between masculinities and men’s workplace health and safety in order to: (i) account for research previously undertaken in this area; (ii) identify themes that may inform our understanding of masculinity and workplace health and safety and; (iii) identify research and practice gaps in relation to men’s workplace health and safety. In this paper we present key themes from this review. Recommendations are made regarding: (i) how to define gender; (ii) how to attend to and identify how masculinities may influence workers’ identities, perceptions of occupational risks and how institutionalized practices can reinforce norms of masculinity; (iii) the importance of considering how masculinities may intersect with other variables (e.g. historical context, age, class, race, geographical location) and; (iv) the added significance of present-day labour market forces on men’s occupational health and safety.

2007-01-01
This article examines five major road-safety risk factors: exceeding posted speed limits, not using safety belts, driving while intoxicated, nighttime driving, and young drivers. The importance of each of these factors is documented, known effective countermeasures (both policy and technology based) are discussed, and impediments to the implementation of these countermeasures in the United States are examined. Based on current understanding of the five major risk factors, and of the available countermeasures, there appear to be a variety of opportunities to make substantial gains in road safety using existing knowledge. The limited implementation of a variety of known countermeasures therefore appears to be inconsistent with high-level, strategic goals to improve road safety. Consequently, a recommendation is made to comprehensively re-examine the balance between the countermeasures discussed in this article and economic, mobility, and privacy concerns. IMPACT ON PUBLIC SAFETY: Such a re-examination is likely to result in broad support for these countermeasures, with a consequent major improvement in road safety.

New graduate registered nurses' knowledge of patient safety and practice: A literature review.
Murray, Melanie; Sundin, Deborah; Cope, Vicki
2018-01-01
To critically appraise available literature and summarise evidence pertaining to the patient safety knowledge and practices of new graduate registered nurses. Responsibility for patient safety should not be limited to the practice of the bedside nurses, rather the responsibility of all in the healthcare system. Previous research identified lapses in safety across the health care, more specifically with new practitioners. Understanding these gaps and what may be employed to counteract them is vital to ensuring patient safety. A focused review of research literature. The review used key terms and Boolean operators across a 5-year time frame in CINAHL, Medline, psycINFO and Google Scholar for research articles pertaining to the area of enquiry. Eighty-four articles met the inclusion criteria, 39 discarded due to irrelevant material and 45 articles were included in the literature review. This review acknowledges that nursing has different stages of knowledge and practice capabilities. A theory-practice gap for new graduate registered nurses exists, and transition to practice is a key learning period setting new nurses on the path to becoming expert practitioners. Within the literature, there was little to no acknowledgement of patient safety knowledge of the newly registered nurse. Issues raised in the 1970s remain a concern for today's new graduate registered nurses. Research has recognised several factors affecting transition from nursing student to new graduate registered nurse. These factors are leaving new practitioners open to potential errors and risking patient safety. Understanding the knowledge of a new graduate registered nurse upon entering clinical practice may assist in organisations providing appropriate clinical and theoretical support to these nurses during their transition. © 2017 John Wiley & Sons Ltd.

To assess food safety practices, food shopping preferences, and eating behaviors of people diagnosed with Salmonella or Campylobacter infection in the warm seasons, and to identify socioeconomic factors associated with behavior and practices. A cross-sectional survey was conducted among Salmonella and Campylobacter cases with onset of illness from January 1 to March 31, 2013. Multivariable logistic regression analyses examined relationships between socioeconomic position and food safety knowledge and practices, shopping and food preferences, and preferences, perceptions, and knowledge about food safety information on warm days. Respondents in our study engaged in unsafe personal and food hygiene practices. They also carried out unsafe food preparation practices, and had poor knowledge of foods associated with an increased risk of foodborne illness. Socioeconomic position did not influence food safety practices. We found that people's reported eating behaviors and food preferences were influenced by warm weather. Our study has explored preferences and practices related to food safety in the warm season months. This is important given that warmer ambient temperatures are projected to rise, both globally and in Australia, and will have a substantial effect on the burden of infectious gastroenteritis including foodborne disease. Our results provide information about modifiable behaviors for the prevention of foodborne illness in the household in the warm weather and the need for information to be disseminated across the general population. An understanding of the knowledge and factors associated with human behavior during warmer weather is critical for public health interventions on foodborne prevention.
Fishing in urban New Jersey: Ethnicity affects information sources, perception and compliance

Recreational and subsistence angling are important aspects of urban culture for much of North American where people are concentrated near the coasts or major rivers. Yet there are fish and shellfish advisories for many estuaries, rivers, and lakes, and these are not always heeded. This paper examines fishing behavior, sources of information, perceptions, and compliance with fishing advisories as a function of ethnicity for people fishing in the Newark Bay Complex of the New York-New Jersey Harbor. The authors test the null hypothesis that there were no ethnic differences in sources of information, perceptions of the safety of fish consumption,more » and compliance with advisories. There were ethnic differences in consumption rates, sources of information about fishing, knowledge about the safety of the fish, awareness of fishing advisories or of the correct advisories, and knowledge about risks for increased cancer and to unborn and young children. In general, the knowledge base was much lower for Hispanics, was intermediate for blacks, and was greatest for whites. When presented with a statement about the potential risks from eating fish, there were no differences in their willingness to stop eating fish or to encourage pregnant women to stop. These results indicate a willingness to comply with advisories regardless of ethnicity, but a vast difference in the base knowledge necessary to make an informed risk decisions about the safety of fish and shellfish. Although the overall median income level of the population was in the $25,000--34,999 income category, for Hispanics it was on the border between $15,000--24,999 and $25,000--34,999.« less
Trends and priorities in occupational health research and knowledge transfer in Italy.
Rondinone, Bruna Maria; Boccuni, Fabio; Iavicoli, Sergio
2010-06-01
In 2000-2001, the Italian National Institute for Occupational Safety and Prevention (ISPESL) carried out a survey to identify the research priorities in the field of occupational safety and health (OSH). The present study, carried out in 2007-2008, was a follow-up designed to (i) review the themes identified earlier, (ii) detect emerging issues linked to new risks and forms of work, and (iii) look for any shifts in focus. The survey was extended to cover not only research but also the concept of knowledge transfer. In the first round, ISPESL distributed questionnaires to the heads of both university occupational medicine departments and prevention departments in local national health units (known as ASL in Italy) asking respondents to identify OSH priority themes. In the latest survey covering both research and the need for knowledge transfer, the same experts were asked to rank the importance of the earlier-identified topics and list any emerging issues in the OSH field. The two most important themes identified were "work accidents" and "occupational carcinogenesis". In the overall sample and among ASL experts, they received the 1st and 2nd highest mean scores. The university respondents also prioritized them but in reverse order. Some of the new priority topics included: risks associated with nanotechnologies; assessment of psychosocial and organizational risks; migration and work; and cost-benefit analysis of prevention. In light of the findings, efforts are urgently needed to identify research and knowledge transfer priorities related to workers' health and safety on an international scale using a standardized method in order to obtain comparable results, avoid wasteful duplication of resources, and reduce occupational accidents and illness.
Engineered nanomaterials: exposures, hazards, and risk prevention
2011-01-01
Nanotechnology presents the possibility of revolutionizing many aspects of our lives. People in many settings (academic, small and large industrial, and the general public in industrialized nations) are either developing or using engineered nanomaterials (ENMs) or ENM-containing products. However, our understanding of the occupational, health and safety aspects of ENMs is still in its formative stage. A survey of the literature indicates the available information is incomplete, many of the early findings have not been independently verified, and some may have been over-interpreted. This review describes ENMs briefly, their application, the ENM workforce, the major routes of human exposure, some examples of uptake and adverse effects, what little has been reported on occupational exposure assessment, and approaches to minimize exposure and health hazards. These latter approaches include engineering controls such as fume hoods and personal protective equipment. Results showing the effectiveness - or lack thereof - of some of these controls are also included. This review is presented in the context of the Risk Assessment/Risk Management framework, as a paradigm to systematically work through issues regarding human health hazards of ENMs. Examples are discussed of current knowledge of nanoscale materials for each component of the Risk Assessment/Risk Management framework. Given the notable lack of information, current recommendations to minimize exposure and hazards are largely based on common sense, knowledge by analogy to ultrafine material toxicity, and general health and safety recommendations. This review may serve as an overview for health and safety personnel, management, and ENM workers to establish and maintain a safe work environment. Small start-up companies and research institutions with limited personnel or expertise in nanotechnology health and safety issues may find this review particularly useful. PMID:21418643
Current safety issues with quadrivalent meningococcal conjugate vaccines.
Myers, Tanya R; McNeil, Michael M
2018-05-04
Invasive meningococcal disease, although rare, can present as sudden, life-threatening disease with high risk of mortality or severe long-term sequelae. The main prevention strategy for invasive meningococcal disease in the United States is the routine vaccination of adolescents and other persons at increased risk of meningococcal disease with quadrivalent meningococcal conjugate vaccines. Two such vaccines are currently licensed and available in the United States, Menactra® (Sanofi Pasteur) and Menveo® (GlaxoSmithKline), and usage in the adolescent population has steadily increased since their introduction. Although early reports raised concerns about a possible association of Menactra with Guillain-Barré syndrome, a comprehensive safety review determined that if such risk existed it was no more than 0.66 cases per 1 million vaccinations. More recently, a study found an elevated risk of Bell's palsy when Menveo was administered concomitantly with other vaccines but no association was found when the vaccine was administered alone. In this commentary, we describe the current state of knowledge with respect to the safety of quadrivalent meningococcal conjugate vaccines, and we identify potential areas for safety research for these vaccines.

Current research on the nanotechnology industry indicates its downstream expansion at a rapid pace, while toxicological research and best practices for environmental health and safety are still being developed. Companies that use and/or produce engineered nanomaterials (ENMs) have enormous potential to influence safe-handling practices for ENMs across the product life cycle. Knowledge of both industry practices and leaders' perceptions of risk is vital for understanding how companies will act to control potential environmental and health risks. This article reports results from a new international survey of nanomaterials companies in 14 countries. In this survey, company participants reported relatively high levels of uncertainty and/or perceived risk with regard to ENMs. However, these perspectives were not accompanied by expected risk-avoidant practices or preferences for regulatory oversight. A majority of companies indicated "lack of information" as a significant impediment to implementing nano-specific safety practices, but they also reported practices that were inconsistent with widely available guidance. Additionally, in the absence of safe-handling regulations, companies reported nano-specific health and safety programs that were narrow in scope. Taken together, these findings indicate that health and safety guidance is not reaching industry. While industry leaders' reluctance toward regulation might be expected, their own reported unsafe practices and recognition of possible risks suggest a more top-down approach from regulators is needed to protect workers and the environment.

The organization of safety in the working places and the increasing attention to behaviours and life styles of workers that may lead to increasing occupational risks are the pick innovative aspects of the recent changes in our country's legislation about occupational safety. In this organization, the role of the company physician is becoming more and more important and his work of evaluation beginning with the knowledge both of the working places and of the workers's lifestyles, is irreplaceable. His role in organizing the managing standards of occupational safety and health cannot be limited to health supervision but must be an essential element in risk assessment in the prevision of workplaces and of safe working conditions, in workers training and information, in organizing the control system of each business. The present paper examines--referring to the current regulation--the duties and functions of a company physician when facing the problems concerning the working risks tied to alcohol assumption.

The purpose of this project was to evaluate a water safety curriculum in a low-income, minority-focused, urban youth summer camp. The curriculum is available to Safe Kids Coalitions across the country; however, it has not previously been evaluated. Participants were pre-K to third-grade students (n = 166). Children watched a video and received the curriculum in a classroom setting. Each child was given a pre-, post-, and 3-week retention exam to assess knowledge change. Mean test scores and number of safety rules participants could list were analyzed using paired Student's t tests. Parents were given a baseline survey at the beginning (n = 140) and end of the weeklong curriculum (n = 118). The participants were 50% male, 27.5% Hispanic, 68.7% African American, and 3.8% biracial. Children were divided into three groups: pre-K/kindergarten, first and second grade, and third grade. Children in each of the groups received higher knowledge scores at the posttest (p = .0097, p < .0001, and p < .0001, respectively), with little decline in scores at the 3-week retention exam. Similar results were seen for the ability to list safety rules, though the number fell slightly between the posttest and retention test. The study demonstrates that children possessed more knowledge of water safety after receiving this curriculum. This knowledge increase was maintained through the 3-week retention exam. Further evaluation of the curriculum's content and its impact on water safety beliefs, attitudes, and behaviors are needed, as well as evaluation of additional settings, risk areas, and the role of parental involvement.

Objective: To determine if a video used during logger training influences safety attitude, knowledge, and workplace habits. Method: From April 2002 to October 2003, loggers receiving training through the West Virginia Division of Forestry were given a new safety module. This consisted of a pre-training survey, viewing video, brief introduction to field safety guide, and an immediate post-training survey. Six months after training, loggers were contacted by telephone to assess workplace behavioral changes. Results: 1197 loggers attended 80 training sessions and completed surveys; 21% were contacted at follow up. Pre-training surveys indicated that half said "accidents" were part of the job and had experienced a "close call" in their work. An overwhelming majority felt that safety management and periodic meetings were important. Over 75% indicated they would not take risks in order to make a profit. Several statistically significant improvements were noted in safety knowledge after viewing the video: logger's location in relation to the tree stump during fatal incidents and the pictorial identification of an overloaded truck and the safest cutting notch. At follow up, many of the loggers said they related to the real life victim stories portrayed in the video. Further, the field guide served as a quick and easy reference and taught them valuable tips on safe cutting and felling. Conclusions: Significant changes in safety knowledge and attitude among certified loggers resulted from viewing the video during training. Subsequent use of the video and field guide at the worksite encouraged positive change in self reported work habits and practices. PMID:15314051
Awareness and Need for Knowledge of Health and Safety among Dairy Farmers Interviewed in Uganda.
Lunner-Kolstrup, Christina; Ssali, Tonny Kiggundu

Safe working conditions are essential for healthy living and for ensuring food security among farmers and farm communities in developing countries. There is limited research on this topic, and documentation is essential to understand and change patterns of human health and safety. In May 2014, six male and female farmers on four dairy farms in Uganda and a female veterinarian were interviewed about their awareness and attitudes to agricultural risk factors, health, and safety. In addition, transect walks were conducted on the four dairy farms. The dairy farmers reported health and safety concerns, e.g., diarrhea, coughs, fever, cuts while using machetes in plantations, bruises when handling animals, and dizziness and poisoning symptoms from using different agrochemicals, and considered these an occupational hazard. The most important topic mentioned was the use of agrochemicals and drugs on livestock. The farmers spray their animals with insecticides to prevent ticks, lice, tsetse flies, and other biting nuisance flies, using a backpack or hand sprayer. Spraying is conducted without personal protection equipment, which is considered too expensive and difficult to obtain. The farmers reported that they usually feel dizzy, vomit, and have pain and a burning feeling in their face and eyes after spraying. The symptoms are sometimes so severe that they require treatment. In such cases, the farmers buy medication without a prescription at the local drugstore, where the storekeeper often has limited or no knowledge of agrochemicals or drugs except for dosage. Agricultural health and safety training in the region is non-existent, and the farmers expressed a need and desire for improvements in this area. The level of knowledge and awareness of agricultural health and safety risks, disease, and injury prevention among the Ugandan dairy farmers interviewed was low. The farmers mentioned few agriculture-related complaints, injuries, or diseases except poisoning from using agrochemicals. Training on health and safety in Ugandan agriculture is urgently needed.
Microbiological risk assessment for personal care products.

Regulatory decisions regarding microbiological safety of cosmetics and personal care products are primarily hazard-based, where the presence of a potential pathogen determines decision-making. This contrasts with the Food industry where it is a commonplace to use a risk-based approach for ensuring microbiological safety. A risk-based approach allows consideration of the degree of exposure to assess unacceptable health risks. As there can be a number of advantages in using a risk-based approach to safety, this study explores the Codex Alimentarius (Codex) four-step Microbiological Risk Assessment (MRA) framework frequently used in the Food industry and examines how it can be applied to the safety assessment of personal care products. The hazard identification and hazard characterization steps (one and two) of the Codex MRA framework consider the main microorganisms of concern. These are addressed by reviewing the current industry guidelines for objectionable organisms and analysing reports of contaminated products notified by government agencies over a recent 5-year period, together with examples of reported outbreaks. Data related to estimation of exposure (step three) are discussed, and examples of possible calculations and references are included. The fourth step, performed by the risk assessor (risk characterization), is specific to each assessment and brings together the information from the first three steps to assess the risk. Although there are very few documented uses of the MRA approach for personal care products, this study illustrates that it is a practicable and sound approach for producing products that are safe by design. It can be helpful in the context of designing products and processes going to market and with setting of microbiological specifications. Additionally, it can be applied reactively to facilitate decision-making when contaminated products are released on to the marketplace. Currently, the knowledge available may only allow a qualitative or semi-quantitative rather than fully quantitative risk assessment, but an added benefit is that the disciplined structuring of available knowledge enables clear identification of gaps to target resources and if appropriate, instigate data generation. © 2016 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

To assess the effects of gender and parental status of dog owners on knowledge of and attitudes toward factors associated with dog aggression directed toward children. Prevalence survey. 804 dog owners. A questionnaire was distributed to owners of all dogs examined at a university veterinary hospital between January and April 2007. Respondents were asked to indicate whether they agreed or disagreed with 37 statements regarding dog behavior and safety practices for dog-child interactions. Responses were compared between women and men and between parents and nonparents. Of 804 questionnaires that were completed, 421 (52%) were completed by parents and 598 (74%) were completed by women. There was a general lack of knowledge regarding dog behavior and safety practices for dog-child interactions. Women were more knowledgeable than men, regardless of parental status. Mothers were more knowledgeable than fathers and female nonparents regarding interactions with young children and had greater awareness than female nonparents and males (regardless of parental status) regarding interactions with infants and toddlers. Results suggested that dog owners frequently had only limited knowledge of dog behavior and often were unaware of factors that increased the risk of dog bites to children. The veterinary examination presents an important opportunity for education of dog owners regarding dog behavior, including body language, social signals, resource-guarding, and self-defense, and the risks of dog bites to infants and young children.

While largely preventable, fire and hot water-related injuries are common in the United States. Measures recommended to reduce these injuries are smoke alarms (SAs) and lowered hot water temperatures. This study aims to: (i) describe the prevalence of working SAs and safe water temperatures among low-income, urban communities and (ii) explore the relationship between these behaviors and individuals' knowledge and beliefs about them. In this cross-sectional study, the Health Belief Model was used as a guide for understanding the safety behaviors. A total of 603 households had their SAs and hot tap water temperatures tested and were surveyed about their knowledge and beliefs related to these safety behaviors. We found that 40% of households had working SAs on every level and 57% had safe hot water temperatures. Perceived severity and self-efficacy were significantly associated with SA coverage, whereas perceived susceptibility and beliefs about benefits were significantly associated with safe hot water temperatures. This study demonstrates the need to increase the number of homes with working SAs and safe hot water temperatures. Messages focused on a safe home environment could communicate the ease and harm reduction features of SAs and benefits and risk reduction features of safe hot water temperatures.

Discussions from a workshop to guide UCLA and NASA investigators on the state of knowledge and perceived needs in spacecraft fire safety and its risk management are reviewed, for an introduction to an analytical and experimental project in this field. The report summarizes the workshop discussions and includes the visual aids used in the presentations. Probabilistic Safety Assessment (PSA) methods, which are currently not used, would be of great value to the designs and operation of future human-crew spacecraft. Key points in the discussions were the importance of understanding and testing smoldering as a likely fire scenario in space and the need for smoke damage modeling, since many fire-risk models ignore this mechanism and consider only heat damage.

Recent critiques of incident reporting suggest that its role in managing safety has been over emphasized. The objective of this study was to examine the perceived effectiveness of incident reporting in improving safety in mental health and acute hospital settings by asking staff about their perceptions and experiences. Qualitative research design using documentary analysis and semi-structured interviews. Two large teaching hospitals in London; one providing acute and the other mental healthcare. Sixty-two healthcare practitioners with experience of reporting and analysing incidents. Incident reporting was perceived as having a positive effect on safety, not only by leading to changes in care processes but also by changing staff attitudes and knowledge. Staff discussed examples of both instrumental and conceptual uses of the knowledge generated by incident reports. There are difficulties in using incident reports to improve safety in healthcare at all stages of the incident reporting process. Differences in the risks encountered and the organizational systems developed in the two hospitals to review reported incidents could be linked to the differences we found in attitudes to incident reporting between the two hospitals. Incident reporting can be a powerful tool for developing and maintaining an awareness of risks in healthcare practice. Using incident reports to improve care is challenging and the study highlighted the complexities involved and the difficulties faced by staff in learning from incident data.
Identifying knowledge-attitude-practice gaps to enhance HPV vaccine diffusion.
Cohen, Elisia L; Head, Katharine J
2013-01-01
To examine differences in knowledge, attitudes, and related practices among adopters and nonadopters of the human papillomavirus (HPV) vaccine, the researchers conducted 83 in-depth interviews with 18- to 26-year-old women. The study identified knowledge-attitude-practice gaps in the context of the HPV vaccine to explain why diffusion of a preventive innovation (such as the HPV vaccine) requires targeted risk communication strategies in order to increase demand. Salient findings included similarities between vaccinated and unvaccinated women's lack of knowledge and uncertainties about HPV and cervical cancer. Vaccinated women who had no knowledge of HPV or no-risk/low-risk perceptions of HPV reported receiving vaccination, indicating HPV risk protection behavior could precede knowledge acquisition for vaccinated women. These vaccinated women identified an interpersonal network supportive of vaccination and reported supportive social influences. Among unvaccinated women, unsupportive vaccination attitudes included low perceived personal risk of HPV. In contrast, unvaccinated women often cited erroneous beliefs that HPV could be avoided by abstinence, monogamy, and knowledge of their partners' sexual history as reasons that the vaccine was not personally relevant. Unvaccinated women cited interpersonal influences that activated short- and long-term vaccination safety and efficacy concerns. Different levels of fear regarding the HPV vaccine may underlie (a) attitudinal differences between vaccinated and unvaccinated women in perceived vaccination value and (b) attitude-practice gaps.
Electronic Nicotine Delivery Systems (ENDS): What Nurses Need to Know.
Essenmacher, Carol; Naegle, Madeline; Baird, Carolyn; Vest, Bridgette; Spielmann, Rene; Smith-East, Marie; Powers, Leigh
Efforts to decrease adverse effects of tobacco use are affected by emergence of new nicotine delivery products. Advertising, product promotion, and social media promote use of these products, yet a lack of evidence regarding safety leaves nurses unprepared to counsel patients. To critically evaluate current research, reviews of literature, expert opinion, and stakeholder policy proposals on use and safety of electronic nicotine delivery systems (ENDS). A targeted examination of literature generated by key stakeholders and subject matter experts was conducted using key words, modified by risk factors, and limited to the past 8 years. Current knowledge gaps in research literature and practice implications of the literature are discussed. The safety of ENDS is questionable and unclear. There are clear health risks of nicotine exposure to developing brains. Potential health risks of ENDS secondhand emissions exposure exist. Using ENDS to facilitate total tobacco cessation is not proven.
Professional drivers: protection needed for a high-risk occupation.

"On the job" motor vehicle deaths number more than 4,000 annually in the U.S. and comprise nearly one-third of all work-related deaths. Yet the Department of Labor has set no standards relating to on-the-road safety of the millions of workers whose jobs entail large amounts of driving, and Department of Transportation standards affecting occupational safety cover only drivers in interstate commerce. Drivers of some commercial vehicles, such as heavy trucks, are at special risk of injury because trucks have usually been exempted for many years from federal motor vehicle safety standards--such as standards for brakes and seatbelts--designed to prevent crashes or protect occupants in crashes. Observations based on a series of 150 fatal crashes involving tractor trailers illustrate the need for better protection of this large population of high-risk workers. Clarification of responsibility within the various federal agencies and application of available knowledge and technology are essential. PMID:937611

Child safety restraints can reduce risk of death and decrease injury severity from road traffic crashes; however, knowledge about restraints and their use in Kuwait is limited. A cross-sectional, self-administered survey about child car safety was used among a convenience sample of parents of children aged 18 years or younger at five Kuwaiti university campuses. Of 552 respondents, over 44% have seated a child in the front seat and 41.5% have seated a child in their lap while driving. Few parents are aware of and fewer report using the appropriate child restraint; e.g., 36% of parents of infants recognised an infant seat and 26% reported using one. Over 70% reported wearing seat belts either "all of the time" (33%) or "most of the time" (41%). This new information about parents' knowledge and practice regarding child car seat use in Kuwait can inform interventions to prevent child occupant injury and death.
Fire behavior and risk analysis in spacecraft

Practical risk management for present and future spacecraft, including space stations, involves the optimization of residual risks balanced by the spacecraft operational, technological, and economic limitations. Spacecraft fire safety is approached through three strategies, in order of risk: (1) control of fire-causing elements, through exclusion of flammable materials for example; (2) response to incipient fires through detection and alarm; and (3) recovery of normal conditions through extinguishment and cleanup. Present understanding of combustion in low gravity is that, compared to normal gravity behavior, fire hazards may be reduced by the absence of buoyant gas flows yet at the same time increased by ventilation flows and hot particle expulsion. This paper discusses the application of low-gravity combustion knowledge and appropriate aircraft analogies to fire detection, fire fighting, and fire-safety decisions for eventual fire-risk management and optimization in spacecraft.

The European Food Safety Authority (EFSA) is responsible for food safety risk assessments at EU level. It provides independent scientific advice on risks associated with the food chain to support EU risk management decisions. Since its establishment, EFSA has amassed a wealth of data to underpin its risk assessments, such as food consumption data, monitoring data and experimental data. Increasing transparency of its risk assessments is a core objective of EFSA. EFSA aims to enhance the quality and transparency of its outputs by giving insofar as possible access to data and methods underpinning its scientific outputs. This paper provides an overview of the role of EFSA, its core data collections and their regulatory framework, as well as data quality and standardisation aspects. Finally, the paper elaborates on EFSA’s 2020 strategy in relation to data, and describes EFSA scientific data warehouse and Knowledge Junction in this regard.
Mining hidden knowledge for drug safety assessment: topic modeling of LiverTox as a case study
2014-01-01
Background Given the significant impact on public health and drug development, drug safety has been a focal point and research emphasis across multiple disciplines in addition to scientific investigation, including consumer advocates, drug developers and regulators. Such a concern and effort has led numerous databases with drug safety information available in the public domain and the majority of them contain substantial textual data. Text mining offers an opportunity to leverage the hidden knowledge within these textual data for the enhanced understanding of drug safety and thus improving public health. Methods In this proof-of-concept study, topic modeling, an unsupervised text mining approach, was performed on the LiverTox database developed by National Institutes of Health (NIH). The LiverTox structured one document per drug that contains multiple sections summarizing clinical information on drug-induced liver injury (DILI). We hypothesized that these documents might contain specific textual patterns that could be used to address key DILI issues. We placed the study on drug-induced acute liver failure (ALF) which was a severe form of DILI with limited treatment options. Results After topic modeling of the "Hepatotoxicity" sections of the LiverTox across 478 drug documents, we identified a hidden topic relevant to Hy's law that was a widely-accepted rule incriminating drugs with high risk of causing ALF in humans. Using this topic, a total of 127 drugs were further implicated, 77 of which had clear ALF relevant terms in the "Outcome and management" sections of the LiverTox. For the rest of 50 drugs, evidence supporting risk of ALF was found for 42 drugs from other public databases. Conclusion In this case study, the knowledge buried in the textual data was extracted for identification of drugs with potential of causing ALF by applying topic modeling to the LiverTox database. The knowledge further guided identification of drugs with the similar potential and most of them could be verified and confirmed. This study highlights the utility of topic modeling to leverage information within textual drug safety databases, which provides new opportunities in the big data era to assess drug safety.

Petrochemical industries are known as sources of many toxic chemicals. Safety and health risks of the petrochemical workers employed at Map Ta Phut Industrial Estate, located in Rayong, Thailand, are potentially high. The research materials consisted of documents emanating from statutory reports on safety in working with toxic chemicals and the results of interviews by questionnaire among 457 petrochemical workers regarding occupational health and safety issues. Most of workers who were working with toxic chemicals had knowledge and awareness of health risks and chemical hazards at work. We found that safe behavior at work through read the safety information among operational workers less than non-operational workers around 10%. Most of workers had perceived occupational health and safety management in their companies. Some companies revealed that they had not been performing biological monitoring of blood or urine for their health examination reports and that workplace exposure monitoring had not correlated well with health examination of workers. Our study suggested that occupational health and safety for petrochemical industries requires standards and guidelines for workers' health surveillance aimed at protection of workers.

Safety netting is a diagnostic strategy used in UK primary care to ensure patients are monitored until their symptoms or signs are explained. Despite being recommended in cancer diagnosis guidelines, little evidence exists about which components are effective and feasible in modern-day primary care. To understand the reality of safety netting for cancer in contemporary primary care. A qualitative study of GPs in Oxfordshire primary care. In-depth interviews with a purposive sample of 25 qualified GPs were undertaken. Interviews were recorded and transcribed verbatim, and analysed thematically using constant comparison. GPs revealed uncertainty about which aspects of clinical practice are considered safety netting. They use bespoke personal strategies, often developed from past mistakes, without knowledge of their colleagues' practice. Safety netting varied according to the perceived risk of cancer, the perceived reliability of each patient to follow advice, GP working patterns, and time pressures. Increasing workload, short appointments, and a reluctance to overburden hospital systems or create unnecessary patient anxiety have together led to a strategy of selective active follow-up of patients perceived to be at higher risk of cancer or less able to act autonomously. This left patients with low-risk-but-not-no-risk symptoms of cancer with less robust or absent safety netting. GPs would benefit from clearer guidance on which aspects of clinical practice contribute to effective safety netting for cancer. Practice systems that enable active follow-up of patients with low-risk-but-not-no-risk symptoms, which could represent malignancy, could reduce delays in cancer diagnosis without increasing GP workload. © British Journal of General Practice 2018.

In case of contamination in the food chain, fast action is required in order to reduce the numbers of affected people. In such situations, being able to predict the fate of agents in foods would help risk assessors and decision makers in assessing the potential effects of a specific contamination event and thus enable them to deduce the appropriate mitigation measures. One efficient strategy supporting this is using model based simulations. However, application in crisis situations requires ready-to-use and easy-to-adapt models to be available from the so-called food safety knowledge bases. Here, we illustrate this concept and its benefits by applying the modular open source software tools PMM-Lab and FoodProcess-Lab. As a fictitious sample scenario, an intentional ricin contamination at a beef salami production facility was modelled. Predictive models describing the inactivation of ricin were reviewed, relevant models were implemented with PMM-Lab, and simulations on residual toxin amounts in the final product were performed with FoodProcess-Lab. Due to the generic and modular modelling concept implemented in these tools, they can be applied to simulate virtually any food safety contamination scenario. Apart from the application in crisis situations, the food safety knowledge base concept will also be useful in food quality and safety investigations. PMID:26247028

[Objectives and limits of test standards].
Kaddick, C; Blömer, W

Test standards are developed worldwide by extremely committed expert groups working mostly in an honorary capacity and have substantially contributed to the currently achieved safety standards in reconstructive orthopedics. Independent of the distribution and quality of a test specification, the specialist knowledge of the user cannot replace a well founded risk analysis and if used unthinkingly can lead to a false estimation of safety. The limits of standardization are reached where new indications or highly innovative products are concerned. In this case the manufacturer must undertake the time and cost-intensive route of a self-developed testing procedure which in the ideal case leads to a further testing standard. Test standards make a substantial contribution to implant safety but cannot replace the expert knowledge of the user. Tests as an end to themselves take the actual objectives of standardization to absurdity.

For both marketing authorization holders and regulatory authorities, evaluating the effectiveness of risk minimization measures is now an integral part of pharmacovigilance in the European Union. The overall aim of activities in this area is to assess the performance of risk minimization measures implemented in order to ensure a positive benefit-risk balance in patients treated with a medicinal product. Following a review of the relevant literature, we developed a conceptual framework consisting of four domains (data, knowledge, behaviour and outcomes) intended for the evaluation of risk minimization measures put into practice in the Danish health-care system. For the implementation of the framework, four classes of monitoring variables can be named and defined: patient descriptors, performance-related indicators of knowledge, behaviour and outcomes. We reviewed the features of the framework when applied to historical, real-world data following the introduction of dabigatran in Denmark for the prophylactic treatment of patients with non-valvular atrial fibrillation. The application of the framework provided useful graphical displays and an opportunity for a statistical evaluation (interrupted time series analysis) of a regulatory intervention. © 2017 Commonwealth of Australia.

The level of accident in industry is very high caused by lack of knowledge and awareness of workers toward the health and safety. Health and Safety are efforts to create a comfortable and productive atmosphere to accomplish a purpose or goal as maximum risk in the workplace.

The purpose of this study was to evaluate the MORE HEALTH "Respect Not Risk" Firearm Safety Lesson for 3rd-graders in Pinellas County, Florida. Six schools representative of various socioeconomic levels were selected as the test sites. Qualitative and quantitative data were collected. A total of 433 matched pretests/posttests were used to determine the effectiveness of the class in increasing student knowledge about firearm safety. The results revealed a significant increase in the mean scores on the posttest compared with the pretest. Qualitative findings showed the lesson was positively received by both students and teachers, and 65% of responding students reported discussing the lesson with family members. School nurses are encouraged to take a leading role in promoting firearm injury prevention to students.

This study is aimed at identifying the knowledge of nursing students about the subject area of patient safety and its relationship with the teaching of biosecurity. Exploratory qualitative study conducted at the Universidade Federal de Santa Catarina (Federal University of Santa Catarina), with 17 students in the third phase of the Undergraduate Nursing Program. Three categories emerged after an exhaustive reading of the responses caring for self and others; biosecurity and care for the environment; biosecurity: health education and continuing education in health services. The following issues were identified, students' concern about risk prevention, care and self care as prerogatives for patient's safety; and education as a proposal for the minimization of risks. The study of biosecurity is considered important in undergraduate studies, minimizing losses and mistakes in the undergraduate students' conduct.

Nanomaterials are increasingly being added to food handling and packaging materials, or directly, to human food and animal feed. To ensure the safety of such engineered nanomaterials (ENMs), in May 2011, the European Food Safety Authority (EFSA) published a guidance document on Risk assessment of the application of nanoscience and nanotechnologies in the food and feed chain. It states that risk assessment should be performed by following a step-wise procedure. Whenever human or animal exposure to nanomaterials is expected, the general hazard characterisation scheme requests information from in vitro genotoxicity, toxicokinetic and repeated dose 90-day oral toxicity studies in rodents. Numerous prevailing uncertainties with regard to nanomaterial characterisation and their hazard and risk assessment are addressed in the guidance document. This article discusses the impact of these knowledge gaps on meeting the goal of ensuring human safety. The EFSA's guidance on the risk assessment of ENMs in food and animal feed is taken as an example for discussion, from the point of view of animal welfare, on what level of uncertainty should be considered acceptable for human safety assessment of products with non-medical applications, and whether animal testing should be considered ethically acceptable for such products.

In the United States of America, all students and staff have a constitutional right to attend schools that are safe, secure, and successful. Despite this right, at many public schools, education leaders have failed to ensure the safety and high academic achievement of all students. The purpose of this research study is to expand knowledge about…

A survey was conducted to investigate the relationship between knowledge about food safety and actual food handling practices among Spanish university students (mainly from the health sciences disciplines) who usually prepare meals at home. Based on level of education in food safety topics, students were divided in three groups: high, which included students from Food Science and Nutrition; medium, which included students from other health sciences; and low, which included students from non-health-related studies. More than two thirds of the 562 people selected had an accurate knowledge of the eight foodborne pathogens included in the survey, but only 5.2% were able to identify Staphylococcus aureus as a foodborne pathogen. Significant differences in responses were found depending on educational level concerning the food safety topic. For food handling, up to 60% of the responses reflected accurate knowledge of proper storage of prepared meals and washing of hands and materials to avoid cross-contamination. However, with the exception of questions related to storage temperature, there was considerable difference between knowledge and reported behavior. Although 98.6% of the participants recognized the importance of hand washing before and during food preparation, only one quarter (24.4%) affirmed that they washed their hands with soap and water. On questions concerning food practices, more accurate answers were given by the older students. Women answered questions regarding cross-contamination more accurately, whereas men were more accurate in response to questions concerning temperature and food preservation. In general, students with more knowledge of food hygiene had better reported practices, but even these students reported some high-risk behaviors. These results confirm the need to improve educational programs, ensuring that the acquired knowledge actually modifies consumer behavior.

A public workshop entitled "Challenges and strategies to facilitate formulation development of pediatric drug products" focused on current status and gaps as well as recommendations for risk-based strategies to support the development of pediatric age-appropriate drug products. Representatives from industry, academia, and regulatory agencies discussed the issues within plenary, panel, and case-study breakout sessions. By enabling practical and meaningful discussion between scientists representing the diversity of involved disciplines (formulators, nonclinical scientists, clinicians, and regulators) and geographies (eg, US, EU), the Excipients Safety workshop session was successful in providing specific and key recommendations for defining paths forward. Leveraging orthogonal sources of data (eg. food industry, agro science), collaborative data sharing, and increased awareness of the existing sources such as the Safety and Toxicity of Excipients for Paediatrics (STEP) database will be important to address the gap in excipients knowledge needed for risk assessment. The importance of defining risk-based approaches to safety assessments for excipients vital to pediatric formulations was emphasized, as was the need for meaningful stakeholder (eg, patient, caregiver) engagement.

In recent years, the interest in health and safety in the workplace has increased. Agriculture is one of the human work activities with the highest risk indexes. Studies on risk perception of agricultural workers are often referred to as specific risk factors (especially pesticides), but the risk perception plays an important role in preventing every kind of accident and occupational disease. The aim of this research is to test a new method for understanding the relation between risk perception among farmers and the main risk factors to which they are exposed. A secondary aim is to investigate the influence of training in risk perception in agriculture. The data collection was realized using a questionnaire designed to investigate the risk perception; the questionnaire was given to a sample of 119 agricultural workers in central Italy. Through the use of the "principal components analysis" it was possible to highlight and verify the latent dimensions underlying the collected data in comparison with scales of attitudes. Results show that the highest percentage of strong negative attitude is among the people who have worked for more years, while farmers who have worked for fewer years have a marked positive attitude. The analysis of the questionnaires through the synthetic index method (Rizzi index) showed that agricultural workers involved, in particular the elderly workers, have a negative attitude towards safety; workers are hostile to safety measures if they have not attended special training courses.

Patient safety curricula in undergraduate medical education (UME) are often didactic format with little focus on skills training. Despite recent focus on safety, practical training in residency education is also lacking. Assessments of safety skills in UME and graduate medical education (GME) are generally knowledge, and not application-focused. We aimed to develop and pilot a safety-focused simulation with medical students and interns to assess knowledge regarding hazards of hospitalisation. A simulation demonstrating common hospital-based safety threats was designed. A case scenario was created including salient patient information and simulated safety threats such as the use of upper-extremity restraints and medication errors. After entering the room and reviewing the mock chart, learners were timed and asked to identify and document as many safety hazards as possible. Learner satisfaction was assessed using constructed-response evaluation. Descriptive statistics, including per cent correct and mean correct hazards, were performed. All 86 third-year medical students completed the encounter. Some hazards were identified by a majority of students (fall risk, 83% of students) while others were rarely identified (absence of deep venous thrombosis prophylaxis, 13% of students). Only 5% of students correctly identified pressure ulcer risk. 128 of 131 interns representing 49 medical schools participated in the GME implementation. Incoming interns were able to identify a mean of 5.1 hazards out of the 9 displayed (SD 1.4) with 40% identifying restraints as a hazard, and 20% identifying the inappropriate urinary catheter as a hazard. A simulation showcasing safety hazards was a feasible and effective way to introduce trainees to safety-focused content. Both students and interns had difficulty identifying common hazards of hospitalisation. Despite poor performance, learners appreciated the interactive experience and its clinical utility.

Objectives: Compare vaccine knowledge, attitudes and practices of primary care providers for fully vaccinated children and children who are exempt from school immunization requirements. Methods: We conducted a mailed survey of parent-identified primary care providers from four states to measure perceived risks and benefits of vaccination and other key immunization beliefs. Frequencies of responses were stratified by type of provider, identified by exempt versus vaccinated children. Logistic regression was used to calculate odds ratios for responses by provider type. Results: 551 surveys were completed (84.3% response rate). Providers for exempt children had similar attitudes to providers for non-exempt children. However, there were statistically significant increased concerns among providers for exempt children regarding vaccine safety and lack of perceived individual and community benefits for vaccines compared to other providers. Conclusions: The great majority of providers for exempt children had similar attitudes about vaccine safety, effectiveness and benefits as providers of non-exempt children. Although providers for exempt children were more likely to believe that multiple vaccines weaken a child’s immune system and were concerned about vaccine safety and less likely to consider vaccines were beneficial, a substantial proportion of providers of both exempt and vaccinated children have concerns about vaccine safety and believe that CDC underestimates the frequency of vaccine side effects. Effective continuing education of providers about the risks and benefits of immunization and including in vaccine recommendations more information on pre and post licensing vaccine safety evaluations may help address these concerns.

Safety in home care: A research protocol for studying medication management
2010-01-01
Background Patient safety is an ongoing global priority, with medication safety considered a prevalent, high-risk area of concern. Yet, we have little understanding of the supports and barriers to safe medication management in the Canadian home care environment. There is a clear need to engage the providers and recipients of care in studying and improving medication safety with collaborative approaches to exploring the nature and safety of medication management in home care. Methods A socio-ecological perspective on health and health systems drives our iterative qualitative study on medication safety with elderly home care clients, family members and other informal caregivers, and home care providers. As we purposively sample across four Canadian provinces: Alberta (AB), Ontario (ON), Quebec (QC) and Nova Scotia (NS), we will collect textual and visual data through home-based interviews, participant-led photo walkabouts of the home, and photo elicitation sessions at clients' kitchen tables. Using successive rounds of interpretive description and human factors engineering analyses, we will generate robust descriptions of managing medication at home within each provincial sample and across the four-province group. We will validate our initial interpretations through photo elicitation focus groups with home care providers in each province to develop a refined description of the phenomenon that can inform future decision-making, quality improvement efforts, and research. Discussion The application of interpretive and human factors lenses to the visual and textual data is expected to yield findings that advance our understanding of the issues, challenges, and risk-mitigating strategies related to medication safety in home care. The images are powerful knowledge translation tools for sharing what we learn with participants, decision makers, other healthcare audiences, and the public. In addition, participants engage in knowledge exchange throughout the study with the use of participatory data collection methods. PMID:20525363

Ambulatory safety risks including delayed diagnoses or missed abnormal test results are difficult for clinicians to see, because they often occur in the space between visits. Experts advocate greater patient engagement to improve safety, but strategies are limited. Patient access to clinical notes ("OpenNotes") may help close the safety gap between visits. We surveyed patients and families who logged on to the patient portal and had at least one ambulatory note available in the past 12 months at two academic hospitals during June to September 2016, focusing on patient-reported effects of OpenNotes on safety knowledge, behaviors, and attitudes. A total of 6913 (28%) of 24,722 patients at an adult hospital and 3672 (17%) of 21,579 participants at the children's hospital submitted surveys. Approximately 75% of patients and parents each reported that reading notes helped them understand the reason for both tests and referrals, and approximately 50% felt that it helped them complete tests and referrals. Roughly 75% of participants were more likely to check and understand test results. Overall, 97% of participants reported that trust in the provider, activation, patient-provider goal alignment, and teamwork were each better or the same after reading 1 note or more. Nonwhite participants and those with high school education or less were 30% to 50% more likely to report that reading notes helped them complete tests compared with white and more educated respondents, respectively. Overall, the majority of more than 10,000 patients and parents reported reading notes helped them understand and follow through on tests and referrals. As information transparency spreads, OpenNotes can help activate patients and families, facilitate safety behaviors, and forge stronger partnerships with clinicians.

Our facility has seen an increase in the number of cases of children burned in restaurants. Fieldwork has revealed many unsafe serving practices in restaurants in our tristate area. The current research targets what appears to be an underexamined burn-risk environment, restaurants, to examine server knowledge about burn prevention and burn care with customers. Participants included 71 local restaurant servers and 53 servers from various restaurants who were recruited from undergraduate courses. All participants completed a brief demographic form as well as a Burn Knowledge Questionnaire. It was found that server knowledge was low (ie, less than 50% accuracy). Yet, most servers reported that they felt customer burn safety was important enough to change the way that they serve. Additionally, it was found that length of time employed as a server was a significant predictor of servers' burn knowledge (ie, more years serving associated with higher knowledge). Finally, individual items were examined to identify potential targets for developing prevention programs.

Over half of foodborne illness outbreaks occur in restaurants. To combat these outbreaks, many public health agencies require food safety certification for restaurant managers, and sometimes workers. Certification entails passing a food safety knowledge examination, which is typically preceded by food safety training. Current certification efforts are based on the assumption that certification leads to greater food safety knowledge. The Centers for Disease Control and Prevention conducted this study to examine the relationship between food safety knowledge and certification. We also examined the relationships between food safety knowledge and restaurant, manager, and worker characteristics. We interviewed managers (N=387) and workers (N=365) about their characteristics and assessed their food safety knowledge. Analyses showed that certified managers and workers had greater food safety knowledge than noncertified managers and workers. Additionally, managers and workers whose primary language was English had greater food safety knowledge than those whose primary language was not English. Other factors associated with greater food safety knowledge included working in a chain restaurant, working in a larger restaurant, having more experience, and having more duties. These findings indicate that certification improves food safety knowledge, and that complex relationships exist among restaurant, manager, and worker characteristics and food safety knowledge.

The aim of this study was to describe outdoor workers' sun-protective practices, workplace sun-safety culture and sun-protective equipment provision; investigate the association of demographic, personal and occupational factors with sun-protective practices; and identify potential strategies for improving workers' sun protection. The present study used a clustered survey design with randomly identified employers in nine occupations. Employees provided questionnaire measures of demographics, personal characteristics (skin type, skin cancer risk perceptions, tanning attitudes, sun-exposure knowledge), personal occupational sun protection practices (exposure reduction, use of sun-protective clothing, sunscreen and shade), workplace sun-protective equipment provision and perceived workplace sun-safety culture. Summative scores were calculated for attitudes, knowledge, workplace provision and culture. A multivariable model was built with worker and workplace variables as plausible predictors of personal sun protection. In this study, 1,061 workers (69% participation) from 112 workplaces provided sufficient information for analysis. Sex, age, prioritized ethnicity, education and risk perception differed significantly between occupational groups (p<0.001), as did workers' sun-protective practices and workplace sun-protection equipment provision and supportive culture. After adjustment, each one-point increase in Workplace Sun-safety Culture 2013Score (range 12 points) was associated with a 0.16 higher Personal Sun-Protection Score (p<0.001), and each one-point increase in Workplace Provision Score (range 4 points) was associated with a 0.14 higher score (p<0.001). Sun Protection Score was significantly associated with skin response to sun exposure (p<0.001), female sex (p=0.021), tanning attitudes (p=0.022) and occupation (p=0.049), but not ethnicity, age education, knowledge or skin cancer risk perception. Protective equipment provision and sun-protective workplace culture are promising components for the development of comprehensive programmes to improve outdoor workers' sun-protective practices.

Background Opioid-involved overdoses in the United States have dramatically increased in the last 15 years, largely due to a rise in prescription opioid (PO) use. Yet few studies have examined the overdose knowledge and experience of nonmedical PO users. Methods In depth, semi-structured, audio-recorded interviews were conducted with 46 New York City young adults (ages 18–32) who reported using POs nonmedically within the past 30 days. Verbatim interview transcripts were coded for key themes in an analytic process informed by grounded theory. Results Despite significant experience with overdose (including overdose deaths), either personally or within opioid-using networks, participants were relatively uninformed about overdose awareness, avoidance and response strategies, in particular the use of naloxone. Overdose experiences typically occurred when multiple pharmaceuticals were used (often in combination with alcohol) or after participants had transitioned to heroin injection. Participants tended to see themselves as distinct from traditional heroin users, and were often outside of the networks reached by traditional opioid safety/overdose prevention services. Consequently, they were unlikely to utilize harm reduction services, such as syringe exchange programs (SEPs), that address drug users' health and safety. Conclusions These findings suggest that many young adult nonmedical PO users are at high risk of both fatal and non-fatal overdose. There is a pressing need to develop innovative outreach strategies and overdose prevention programs to better reach and serve young PO users and their network contacts. Prevention efforts addressing risk for accidental overdose, including opioid safety/overdose reversal education and naloxone distribution, should be tailored for and targeted to this vulnerable group.

Risk communication aims to promote health and understanding through information exchange; however, explanations regarding the basis of regulation values for the public are insufficient. Moreover, it is unclear how information presentation affects the public’s sense of safety and their consumption intentions. We first investigated the relationship between perception of mercury-risk in fish and shellfish and individual attributes and knowledge. We then examined how presenting information on regulation values and primary factors regarding perception affected sense of safety toward regulations and food-consumption intentions. An online survey was conducted with Japanese individuals (N = 1148). Respondents were randomly assigned to one of three groups based on the presentation level of regulation values. People who frequently consumed tuna had a high perception of dread risk of mercury. This suggests that the dread risk perception of mercury does not determine tuna-type consumption behavior; rather, individuals’ consumption behavior determines dread risk perception of mercury. Among those with high tuna-type consumption, those receiving information that a safety factor of 10 times had been considered showed a significantly greater sense of safety than did the group that was not presented with information on regulation values (odds ratio (95% confidence interval): 2.04 (1.18–3.53), p < 0.05). However, presentation of regulation values showed a weak but significantly positive correlation with excessive intake of tuna-type fish (odds ratio: 2.95 (0.93–9.32), p < 0.10). Presenting the information on regulation values increases sense of safety; however, it may also lead to excessive intake. PMID:29267301
To what extent can theory account for the findings of road safety evaluation studies?
Elvik, Rune
2004-09-01
This paper proposes a conceptual framework that can be used to assess to what extent the findings of road safety evaluation research make sense from a theoretical point of view. The effects of road safety measures are modelled as passing through two causal chains. One of these, termed the engineering effect, refers to the intended effects of a road safety measure on a set of risk factors related to accident occurrence or injury severity. The engineering effect of road safety measures is modelled in terms of nine basic risk factors, one or more of which any road safety measure needs to influence in order to have the intended effect on accidents or injuries. The other causal chain producing the effects of road safety measures is termed the behavioural effect, and refers to road user behavioural adaptations to road safety measures. The behavioural effect is related to the engineering effect, in the sense that certain properties of the engineering effect of a road safety measure influence the likelihood that behavioural adaptation will occur. The behavioural effect of a road safety measure is modelled in terms of six factors that influence the likelihood that behavioural adaptation will occur. The nine basic risk factors representing the engineering effect of a road safety measure, and the six factors influencing the likelihood of behavioural adaptation can be used as checklists in assessing whether or not the findings of road safety evaluation studies make sense from a theoretical point of view. At the current state of knowledge, a more stringent evaluation of the extent to which theory can explain the findings of road safety evaluation studies is, in most cases, not possible.

Background : Approximately 35 new HIV (Human Immunodeficiency Virus, HIV) cases and at least 1000 serious infections are transmitted annually to health care workers. In China, HIV prevalence is increasing and nursing personnel are encountering these individuals more than in the past. Contaminated needle-stick injuries represent a significant occupational burden for nurses. Evidence suggests that nurses in China may not fully understand HIV/AIDS (Acquired immunodeficiency syndrome, AIDS) and HIV-related occupational safety. At this time, universal protection precautions are not strictly implemented in Chinese hospitals. Lack of training may place nurses at risk for occupational exposure to blood-borne pathogens. Objectives : To assess the effectiveness of integrated interventions on nurses' knowledge improvement about reducing the risk of occupationally acquired HIV infection. Methods : We audited integrated interventions using 300 questionnaires collected from nurses at the Affiliated Hospital of Xiangnan University, a public polyclinic in Hunan Province. The intervention studied was multifaceted and included appropriate and targeted training content for hospital, department and individual levels. After three months of occupational safety integrated interventions, 234 participants who completed the program were assessed. Results : Of the subjects studied, 94.3% (283/300) were injured one or more times by medical sharp instruments or splashed by body fluids in the last year and 95.3% considered their risk of occupational exposure high or very high. After the intervention, awareness of HIV/AIDS-related knowledge improved significantly ( χ ² = 86.34, p = 0.00), and correct answers increased from 67.9% to 82.34%. Correct answers regarding risk perception were significantly different between pre-test (54.4%) and post-test (66.6%) ( χ ² = 73.2, p = 0.00). When coming into contact with patient body fluids and blood only 24.0% of subjects used gloves regularly. The pre-test knowledge scores on universal precautions were relatively high. Correct answers about universal precautions improved significantly from pre-test (83.71%) to post-test (89.58%; χ ² = 25.00, p = 0.00). After the intervention, nurses' attitude scores improved significantly from pre-test (3.80 ± 0.79) to post-test (4.06 ± 0.75; t = 3.74, p = 0.00). Conclusions : Integrated educational interventions enhance nurses' knowledge of risk reduction for occupationally acquired HIV infections and improve the observance of universal precautionary procedures. This enhancement allows nurses to assume a teaching role for prevention and management of HIV/AIDS.
Sepsis in Poland: Why Do We Die?
Rorat, Marta; Jurek, Tomasz

Objective To investigate the adverse events and potential risk factors in patients who develop sepsis. Subjects and Methods Fifty-five medico-legal opinion forms relating to sepsis cases issued by the Department of Forensic Medicine, Wroclaw, Poland, between 2004 and 2013 were analyzed for medical errors and risk factors for adverse events. Results The most common causes of medical errors were a lack of knowledge in recognition, diagnosis and therapy as well as ignorance of risk. The common risk factors for adverse events were deferral of a diagnostic or therapeutic decision, high-level anxiety of patients or their families about the patient's health and actively seeking for help. The most significant risk factors were communication errors, not enough medical staff, stereotype-based thinking about diseases and providing easy explanations for serious symptoms. Conclusion The most common cause of adverse events related to sepsis in the Polish health-care system was a lack of knowledge about the symptoms, diagnosis and treatment as well as the ignoring of danger. A possible means of improving safety might be through spreading knowledge and creating medical management algorithms for all health-care workers, especially physicians. PMID:25501966

Children are at increased risk for foodborne illness due to underdeveloped immune system. Limited research has been reported on food safety knowledge of Native American families with children 10 years of age and younger. This study was conducted to determine the food safety knowledge, attitudes, and behaviors of the main food preparer in these families by collecting quantitative and qualitative data simultaneously in a mixed method approach. A food safety knowledge survey created using FightBAC! ™ concepts was administered prior to focus groups discussions held in Native American communities using a script based upon the Health Belief Model. Quantitative data were analyzed using SPSS. Qualitative data were coded by three reviewers independently and then compared jointly for themes. Over three fourths of participants (n = 102) were female with an average age of 38.3 years. Over one half of participants were unemployed (54 %), lived on reservations (54 %), and 86 % had a high school degree or higher level of education. The following four themes emerged from the eight focus groups (n = 66): food can make one sick, I am not in control when others handle food, I know how to safely prepare foods for my family, and I do not have time or best equipment (for food safety). Mixed method analysis revealed that participants were aware of the severity and susceptibility for foodborne illness but were confident in preparing foods safely for their family. A food safety education program for Native American food preparers with young children is needed to prevent foodborne illness (FBI) in this population and promote safe food handling practice.
A 21st Century Roadmap for Human Health Risk Assessment ...
For decades human health risk assessment has depended primarily on animal testing to predict adverse effects in humans, but that paradigm has come under question because of calls for more accurate information, less use of animals, and more efficient use of resources. Moreover, the disproportionate use of hazard information has overshadowed the important role of exposure science in determinations of human safety. In addition, major risk assessments lack the clarity and transparency that hinder an understanding of the analysis and communication of key safety messages. To help answer these challenges, the HESI-managed RISK21 project was initiated to develop a scientific, transparent, and efficient approach to the evolving world of human health risk assessment. RISK21 involved over 120 participants from 12 countries, 15 government institutions, 20 universities, 2 non-governmental organizations, and 12 corporations. RISK21 developed a tiered approach that is problem formulation-based, makes maximum use of prior knowledge, and is led by exposure science to produce a highly transparent and flexible visualization of and approach to assessing human safety and risk. The general principles underlying the RISK21 approach as well as an overview of the RISK21 Roadmap are presented here. This paper will be followed by a series of publications that will articulate the details that comprise this systematic approach. The purpose of this manuscript is to provide an overview
Applying health education theory to patient safety programs: three case studies.
Gilkey, Melissa B; Earp, Jo Anne L; French, Elizabeth A
2008-04-01
Program planning for patient safety is challenging because intervention-oriented surveillance data are not yet widely available to those working in this nascent field. Even so, health educators are uniquely positioned to contribute to patient safety intervention efforts because their theoretical training provides them with a guide for designing and implementing prevention programs. This article demonstrates the utility of applying health education concepts from three prominent patient safety campaigns, including the concepts of risk perception, community participation, and social marketing. The application of these theoretical concepts to patient safety programs suggests that health educators possess a knowledge base and skill set highly relevant to patient safety and that their perspective should be increasingly brought to bear on the design and evaluation of interventions that aim to protect patients from preventable medical error.
Occupational safety and health in construction: a review of applications and trends

Due to the high number of accidents that occur in construction and the consequences this has for workers, organizations, society and countries, occupational safety and health (OSH) has become a very important issue for stakeholders to take care of the human resource. For this reason, and in order to know how OSH research in the construction sector has evolved over time, this article–in which articles published in English were studied–presents an analysis of research conducted from 1930 to 2016. The classification of documents was carried out following the Occupational Safety and Health Cycle which is composed of five steps: regulation, education and training, risk assessment, risk prevention, and accident analysis. With the help of tree diagrams we show that evolution takes place. In addition, risk assessment, risk prevention, and accident analysis were the research topics with the highest number of papers. The main objective of the study was to contribute to knowledge of the subject, showing trends through an exploratory study that may serve as a starting point for further research. PMID:28179610

While the ability to develop nanomaterials and incorporate them into products is advancing rapidly worldwide, understanding of the potential health safety effects of nanomaterials has proceeded at a much slower pace. Since 2008, Korea Food and Drug Administration (KFDA) started an investigation to prepare "Strategic Action Plan" to evaluate safety and nano risk management associated with foods, drugs, medical devices and cosmetics using nano-scale materials. Although there are some studies related to potential risk of nanomaterials, physical-chemical characterization of nanomaterials is not clear yet and these do not offer enough information due to their limitations. Their uncertainties make it impossible to determine whether nanomaterials are actually hazardous to human. According to the above mention, we have some problems to conduct the human exposure risk assessment currently. On the other hand, uncertainty about safety may lead to polarized public debate and to businesses unwillingness for further nanotechnology investigation. Therefore, the criteria and methods to assess possible adverse effects of nanomaterials have been vigorously taken into consideration by many international organizations: the World Health Organization, the Organization for Economic and Commercial Development and the European Commission. The object of this study was to develop risk assessment principles for safety management of future nanoproducts and also to identify areas of research to strengthen risk assessment for nanomaterials. The research roadmaps which were proposed in this study will be helpful to fill up the current gaps in knowledge relevant nano risk assessment.

Lay people have difficulty understanding the meaning of environmental health risk information. Visual images can use features that leverage visual perception capabilities and semiotic conventions to promote meaningful comprehension. Such evidence-based features were employed to develop two images of a color-coded visual scale to convey drinking water test results. The effect of these images and a typical alphanumeric (AN) lab report were explored in a repeated measures randomized trial among 261 undergraduates. Outcome measures included risk beliefs, emotions, personal safety threshold, mitigation intentions, the durability of beliefs and intentions over time, and test result recall. The plain image conveyed the strongest risk message overall, likely due to increased visual salience. The more detailed graded image conveyed a stronger message than the AN format only for females. Images only prompted meaningful risk reduction intentions among participants with optimistically biased safety threshold beliefs. Fuzzy trace theory supported some findings as follow. Images appeared to promote the consolidation of beliefs over time from an initial meaning of safety to an integrated meaning of safety and health risk; emotion potentially shaped this process. Although the AN report fostered more accurate recall, images were related to more appropriate beliefs and intentions at both time points. Findings hinted at the potential for images to prompt appropriate beliefs independent of accurate factual knowledge. Overall, results indicate that images facilitated meaningful comprehension of environmental health risk information and suggest foci for further research.

In this paper, a new interpretation of intuitionistic fuzzy sets in the advanced framework of the Dempster-Shafer theory of evidence is extended to monitor safety-critical systems' performance. Not only is the proposed approach more effective, but it also takes into account the fuzzy rules that deal with imperfect knowledge/information and, therefore, is different from the classical Takagi-Sugeno fuzzy system, which assumes that the rule (the knowledge) is perfect. We provide an analytical solution to the practical and important problem of the conceptual probabilistic approach for formal ship safety assessment using the fuzzy set theory that involves uncertainties associated with the reliability input data. Thus, the overall safety of the ship engine is investigated as an object of risk analysis using the fuzzy mapping structure, which considers uncertainty and partial truth in the input-output mapping. The proposed method integrates direct evidence of the frame of discernment and is demonstrated through references to examples where fuzzy set models are informative. These simple applications illustrate how to assess the conflict of sensor information fusion for a sufficient cooling power system of vessels under extreme operation conditions. It was found that propulsion engine safety systems are not only a function of many environmental and operation profiles but are also dynamic and complex. Copyright © 2011 Elsevier Ltd.

We investigated cultural influences on the implementation of water safety plans (WSPs) using case studies from WSP pilots in India, Uganda and Jamaica. A comprehensive thematic analysis of semi-structured interviews (n=150 utility customers, n=32 WSP 'implementers' and n=9 WSP 'promoters'), field observations and related documents revealed 12 cultural themes, offered as 'enabling', 'limiting', or 'neutral', that influence WSP implementation in urban water utilities to varying extents. Aspects such as a 'deliver first, safety later' mind set; supply system knowledge management and storage practices; and non-compliance are deemed influential. Emergent themes of cultural influence (ET1 to ET12) are discussed by reference to the risk management, development studies and institutional culture literatures; by reference to their positive, negative or neutral influence on WSP implementation. The results have implications for the utility endorsement of WSPs, for the impact of organisational cultures on WSP implementation; for the scale-up of pilot studies; and they support repeated calls from practitioner communities for cultural attentiveness during WSP design. Findings on organisational cultures mirror those from utilities in higher income nations implementing WSPs - leadership, advocacy among promoters and customers (not just implementers) and purposeful knowledge management are critical to WSP success.

Therapeutic protein products (TPPs) are of considerable value in the treatment of a variety of diseases, including cancer, hemophilia, and autoimmune diseases. The success of TPP mainly results from prolonged half-life, increased target specificity and decreased intrinsic toxicity compared with small molecule drugs. However, unwanted immune responses against TPP, such as generation of anti-drug antibody, can impact both drug efficacy and patient safety, which has led to requirements for increased monitoring in regulatory studies and clinical practice, termination of drug development, or even withdrawal of marketed products. We present an overview of current knowledge on immunogenicity of TPP and its impact on efficacy and safety. We also discuss methods for measurement and prediction of immunogenicity and review both product-related and patient-related risk factors that affect its development, and efforts that may be taken to mitigate it. Lastly, we discuss gaps in knowledge and technology and what is needed to fill these. Copyright © 2015 Elsevier Inc. All rights reserved.
Promoting culturally competent care for gay youth.
Bakker, Leslie J; Cavender, Angela
2003-04-01
Gay youth and those questioning their sexual identity have been referred to as "hidden," "invisible," "stigmatized," and "marginalized." As a result, the unique safety and health needs of this subculture have been overlooked, or worse, ignored, placing these youth at risk. Because school nurses have been identifying at-risk populations of students and developing programs to promote youth and family health for years, they should be prepared to provide health care for the subculture of gay youth. However, nurses are saying they do not have the knowledge or skills needed to identify and address the needs of this group. Providing school nursing care for gay youth requires the school nurse to be culturally competent. School nurses need to be aware of, sensitive to, and knowledgeable about the subculture. They must also possess communication skills required to relate appropriately to this group. This article presents information and nursing strategies that will promote the safety and health of gay youth while enhancing the school nurse's cultural competence.

Gender medicine is a multi-faceted field of investigation integrating various aspects of psycho-social and biological sciences but it mainly deals with the impact of the gender on human physiology, pathophysiology, and clinical features of diseases. In Italy, the Decree Law 81/2008 recently introduced the gender issue in the risk assessment at the workplaces. This review briefly describes our current knowledge on gender medicine and on the Italian legislation in risk management. Public or private scientific institutions should be the first to pay attention to the safety of their workers, who are simultaneously subjected to biological, chemical and physical agents. Main tasks of risk management in scientific research institutions are here analyzed and discussed in a gender perspective.
Cyber-Informed Engineering: The Need for a New Risk Informed and Design Methodology
DOE Office of Scientific and Technical Information (OSTI.GOV)
Price, Joseph Daniel; Anderson, Robert Stephen
Current engineering and risk management methodologies do not contain the foundational assumptions required to address the intelligent adversary’s capabilities in malevolent cyber attacks. Current methodologies focus on equipment failures or human error as initiating events for a hazard, while cyber attacks use the functionality of a trusted system to perform operations outside of the intended design and without the operator’s knowledge. These threats can by-pass or manipulate traditionally engineered safety barriers and present false information, invalidating the fundamental basis of a safety analysis. Cyber threats must be fundamentally analyzed from a completely new perspective where neither equipment nor human operationmore » can be fully trusted. A new risk analysis and design methodology needs to be developed to address this rapidly evolving threatscape.« less
Setting priorities for reducing risk and advancing patient safety.
Gaffey, Ann D
2016-04-01
We set priorities every day in both our personal and professional lives. Some decisions are easy, while others require much more thought, participation, and resources. The difficult or less appealing priorities may not be popular, may receive push-back, and may be resource intensive. Whether personal or professional, the urgency that accompanies true priorities becomes a driving force. It is that urgency to ensure our patients' safety that brings many of us to work each day. This is not easy work. It requires us to be knowledgeable about the enterprise we are working in and to have the professional skills and competence to facilitate setting the priorities that allow our organizations to minimize risk and maximize value. © 2016 American Society for Healthcare Risk Management of the American Hospital Association.
Hispanic adolescent farmworkers' perceptions associated with pesticide exposure.
Salazar, Mary K; Napolitano, Marie; Scherer, Jennifer A; McCauley, Linda A
2004-03-01
The migrant farmworker population in the United States is a vulnerable and understudied population whose characteristics are constantly shifting. The number of youth involved in agriculture work is increasing, and they, in particular, may be at increased risk for occupational hazards, such as pesticide exposure. The present study utilized an ecological framework for focus group discussions with 33 adolescent migrant farmworkers in Oregon. Adolescents' risk perception and health beliefs associated with pesticide exposure are examined on four levels of environmental influence: microenvironment, organizational environment, social/community environment, and macroenvironment. Adolescents provided insight on such topics as perceived vulnerability of illness due to pesticide exposure, attitudes toward farmwork, influence of their boss, knowledge of occupational hazards, safety training, and barriers to occupational choice. Cultural influences on occupational safety and health are discussed and increased attention to safety training is recommended.
Foundational workplace safety and health competencies for the emerging workforce☆
Okun, Andrea H.; Guerin, Rebecca J.; Schulte, Paul A.
2016-01-01
Introduction Young workers (aged 15–24) suffer disproportionately from workplace injuries, with a nonfatal injury rate estimated to be two times higher than among workers age 25 or over. These workers make up approximately 9% of the U.S. workforce and studies have shown that nearly 80% of high school students work at some point during high school. Although young worker injuries are a pressing public health problem, the critical knowledge and skills needed to prepare youth for safe and healthy work are missing from most frameworks used to prepare the emerging U.S. workforce. Methods A framework of foundational workplace safety and health knowledge and skills (the NIOSH 8 Core Competencies)was developed based on the Health Belief Model (HBM). Results The proposed NIOSH Core Competencies utilize the HBM to provide a framework for foundational workplace safety and health knowledge and skills. An examination of how these competencies and the HBM apply to actions that workers take to protect themselves is provided. The social and physical environments that influence these actions are also discussed. Conclusions The NIOSH 8 Core Competencies, grounded in one of the most widely used health behavior theories, fill a critical gap in preparing the emerging U.S. workforce to be cognizant of workplace risks. Practical applications Integration of the NIOSH 8 Core Competencies into school curricula is one way to ensure that every young person has the foundational workplace safety and health knowledge and skills to participate in, and benefit from, safe and healthy work.

Adverse drug reactions (ADRs) are a major public health concern, causing over 100,000 fatalities in the United States every year with an annual cost of $136 billion. Early detection and accurate prediction of ADRs is thus vital for drug development and patient safety. Multiple scientific disciplines, namely pharmacology, pharmacovigilance, and pharmacoinformatics, have been addressing the ADR problem from different perspectives. With the same goal of improving drug safety, this article summarizes and links the research efforts in the multiple disciplines into a single framework from comprehensive understanding of the interactions between drugs and biological system and the identification of genetic and phenotypic predispositions of patients susceptible to higher ADR risks and finally to the current state of implementation of medication-related decision support systems. We start by describing available computational resources for building drug-target interaction networks with biological annotations, which provides a fundamental knowledge for ADR prediction. Databases are classified by functions to help users in selection. Post-marketing surveillance is then introduced where data-driven approach can not only enhance the prediction accuracy of ADRs but also enables the discovery of genetic and phenotypic risk factors of ADRs. Understanding genetic risk factors for ADR requires well organized patient genetics information and analysis by pharmacogenomic approaches. Finally, current state of clinical decision support systems is presented and described how clinicians can be assisted with the integrated knowledgebase to minimize the risk of ADR. This review ends with a discussion of existing challenges in each of disciplines with potential solutions and future directions. Copyright © 2016 Elsevier Inc. All rights reserved.

Unintentional injury rates in low- and middle-income countries are up to 50 times higher than high-income nations. In South Africa, kerosene (paraffin) is a leading cause of poisoning and burns, particularly in low-income communities where it serves as a primary fuel for light, cooking, and heating. This study tested a community-based intervention to reduce kerosene-related injury risk. The intervention used a train-the-trainers model, whereby expert trainers train local paraprofessionals, who in turn deliver educational materials to community residents. The intervention was theory-driven, pragmatically motivated, and culturally sensitive. Prospective quasi-experimental intervention design with nonequivalent case versus control groups. Three primary outcome measures were considered: self-reported knowledge of kerosene safety, observed practice of safe kerosene use, and self-reported recognition of risk for kerosene-related injury. ANOVA models suggest a large and significant increase in self-reported kerosene-related knowledge in the intervention community compared to the control community. There were smaller, but statistically significant changes, in kerosene-related safety practices and recognition of kerosene injury risk in the intervention community compared to the control community. The intervention was successful. A train-the-trainers model might be an effective educational tool to reduce kerosene-related injury risk in low-income communities within low- and middle-income countries.

Monoclonal antibodies (mAbs) are improving the quality of life for patients suffering from serious diseases due to their high specificity for their target and low potential for off-target toxicity. The toxicity of mAbs is primarily driven by their pharmacological activity, and therefore safety testing of these drugs prior to clinical testing is performed in species in which the mAb binds and engages the target to a similar extent to that anticipated in humans. For highly human-specific mAbs, this testing often requires the use of non-human primates (NHPs) as relevant species. It has been argued that the value of these NHP studies is limited because most of the adverse events can be predicted from the knowledge of the target, data from transgenic rodents or target-deficient humans, and other sources. However, many of the mAbs currently in development target novel pathways and may comprise novel scaffolds with multi-functional domains; hence, the pharmacological effects and potential safety risks are less predictable. Here, we present a total of 18 case studies, including some of these novel mAbs, with the aim of interrogating the value of NHP safety studies in human risk assessment. These studies have identified mAb candidate molecules and pharmacological pathways with severe safety risks, leading to candidate or target program termination, as well as highlighting that some pathways with theoretical safety concerns are amenable to safe modulation by mAbs. NHP studies have also informed the rational design of safer drug candidates suitable for human testing and informed human clinical trial design (route, dose and regimen, patient inclusion and exclusion criteria and safety monitoring), further protecting the safety of clinical trial participants.

Assisted living facilities (ALFs) pose unique fire risks to the elderly that may be linked to specific fire safety (FS) practices. To evaluate self-reported FS practices among ALF residents. All residents of a small ALF were surveyed regarding actual and hypothetical FS behaviors, self-perceived fire risk, and FS preparedness. Fifty-eight ALF residents completed the survey. Thirty-three (58%) individuals reported one or more disabilities. Seven (12%) residents ignored the fire alarm and 21 (35%) could not hear it clearly. Sixteen (28%) residents would attempt to locate the source of a fire rather than escape from the building. Only 24 (42%) residents were familiar with the building fire plan. Twenty-three (40%) people surveyed believed that they were not at risk of fire in the study facility. Residents of an ALF may be at increased fire injury risk due to their FS practices and disabilities.

Since its inception in 2006, the Alliance for Patient Safety in Catalonia has played a major role in promoting and shaping a series of projects related to the strategy of the Ministry of Health, Social Services and Equality, for improving patient safety. One such project was the creation of functional units or committees of safety in hospitals in order to facilitate the management of patient safety. The strategy has been implemented in hospitals in Catalonia which were selected based on criteria of representativeness. The intervention was based on two lines of action, one to develop the model framework and the other for its development. Firstly the strategy for safety management based on EFQM (European Foundation for Quality Management) was defined with the development of standards, targets and indicators to implement security while the second part involved the introduction of tools, methodologies and knowledge to the management support of patient safety and risk prevention. The project was developed in four hospital areas considered higher risk, each assuming six goals for safety management. Some of these targets such as the security control panel or system of adverse event reporting were shared. 23 hospitals joined the project in Catalonia. Despite the different situations in each centre, high compliance was achieved in the development of the objectives. In each of the participating areas the security control panel was developed. Stable structures for safety management were established or strengthened. Training in patient safety played and important role, 1415 professionals participated. Through these kind of projects not only have been introduced programs of proven effectiveness in reducing risks, but they also provide to the facilities a work system that allows autonomy in diagnosis and analysis of the different risk situations or centre specific safety issues.

Neural-tube defects (NTDs) are considered to be the most common congenital malformations. As Shanxi Province, a poor region in the North of China, has one of the highest reported prevalence rates of NTDs in the world, folate fortification of rice is an excellent alternative to low intake of folate acid pills in this region. This paper investigates the relations between socio-demographic indicators, consumer characteristics (knowledge, consumer perceptions on benefits, risks, safety and price), willingness-to-accept and willingness-to-pay genetically modified (GM) rice. The consumer survey compromises 944 face-to-face interviews with rice consumers in Shanxi Province, China. Multivariate analyses consist of multinomial logistic regression and multiple regression. The results indicate that consumers generally are willing-to-accept GM rice, with an acceptance rate of 62.2%. Acceptance is influenced by objective knowledge and consumers' perceptions on benefits and risks. Willingness-to-pay GM rice is influenced by objective knowledge, risk perception and acceptance. Communication towards the use of GM rice should target mainly improving knowledge and consumers' perceptions on high-risk groups within Shanxi Province, in particular low educated women. 2009 Elsevier Ltd.

Implementing a sharps injury reduction program at a charity hospital in India.
Gramling, Joshua J; Nachreiner, Nancy
2013-08-01
Health care workers in India are at high risk of developing bloodborne infections from needlestick injuries. Indian hospitals often do not have the resources to invest in safety devices and protective equipment to decrease this risk. In collaboration with hospital staff, the primary author implemented a sharps injury prevention and biomedical waste program at an urban 60-bed charity hospital in northern India. The program aligned with hospital organizational objectives and was designed to be low-cost and sustainable. Occupational health nurses working in international settings or with international workers should be aware of employee and employer knowledge and commitment to occupational health and safety.

Air, rail and road: Medical Guidelines for Employees with a History of Cerebrovascular Disease.
Klein, Rebecca; Menon, Bijoy K; Rabi, Doreen; Stell, William; Hill, Michael D
2016-10-01
Background An acute medical condition following a previous stroke among those who operate trains, airplanes, and commercial vehicles can result in serious accidents. There are guidelines in place to assist physicians and employers in assessing the risks of returning to work after stroke but the extent and comprehensiveness across nations and among safety-critical occupations are not widely known. Methods Medical guidelines currently in place to regulate safety critical occupations including railway engineers, pilots and commercial vehicle drivers were systematically reviewed. Electronic and hand literature searches as well as review of grey literature for Canada, the USA, the UK, and Australia were conducted. Results There is no consistent set of guidelines that address the risk of a second catastrophic event after an initial cerebrovascular event in those employed in safety critical occupations in the four countries assessed. Some broad principles existed between the different countries and occupations but there was major variation in the approach to cerebrovascular disease and its impact on those working in safety-critical occupations. Conclusions A synthesis of current knowledge would assist in establishing risks of a catastrophic event in those who have already suffered from cerebrovascular illness. This will allow the creation of medical guidelines which could be applied to any safety critical occupation in any nation.
A Safety Evaluation of Empagliflozin for the Treatment of Type 2 Diabetes
Neeland, Ian J.; Salahuddin, Usman; McGuire, Darren K.
2016-01-01
Introduction Empagliflozin is a sodium glucose co-transporter 2 inhibitor used to improve glycemic control in adults with type 2 diabetes mellitus (T2DM) by enhancing urinary glucose excretion. Empagliflozin is effective at lowering glycosylated hemoglobin and was recently proven superior to placebo for reduction of cardiovascular disease (CVD) risk. As with any new drug, there are safety considerations that inform its potential use in patients with T2DM. Areas Covered Here, we evaluate the safety of empagliflozin and provide an expert opinion as to its current and future role in the treatment of patients with T2DM. A search of the English language literature was performed using PubMed search terms: “empagliflozin”, “sodium glucose cotransporter 2 inhibitors”, and “drug safety”. Articles and bibliographies relevant to the subject were reviewed and additional references known to the authors were included. Expert Opinion The evidence for empagliflozin is robust with regard to glycemic efficacy and safety. Low risk of hypoglycemia, absence of weight gain, and demonstrated cardiovascular risk reduction support its consideration as a first line medication in addition to metformin for patients with T2DM and CVD. Ongoing trials will continue to address the safety and efficacy of empagliflozin and expand our clinical knowledge of this medication. PMID:26695551
A Semantic Approach with Decision Support for Safety Service in Smart Home Management
Huang, Xiaoci; Yi, Jianjun; Zhu, Xiaomin; Chen, Shaoli
2016-01-01
Research on smart homes (SHs) has increased significantly in recent years because of the convenience provided by having an assisted living environment. The functions of SHs as mentioned in previous studies, particularly safety services, are seldom discussed or mentioned. Thus, this study proposes a semantic approach with decision support for safety service in SH management. The focus of this contribution is to explore a context awareness and reasoning approach for risk recognition in SH that enables the proper decision support for flexible safety service provision. The framework of SH based on a wireless sensor network is described from the perspective of neighbourhood management. This approach is based on the integration of semantic knowledge in which a reasoner can make decisions about risk recognition and safety service. We present a management ontology for a SH and relevant monitoring contextual information, which considers its suitability in a pervasive computing environment and is service-oriented. We also propose a rule-based reasoning method to provide decision support through reasoning techniques and context-awareness. A system prototype is developed to evaluate the feasibility, time response and extendibility of the approach. The evaluation of our approach shows that it is more effective in daily risk event recognition. The decisions for service provision are shown to be accurate. PMID:27527170

While safety knowledge and safety motivation are well-established predictors of safety participation, less is known about the impact of leadership styles on these relationships. The purpose of the current study was to examine whether the positive relationships between safety knowledge and motivation and safety participation are contingent on transformational and passive forms of safety leadership. Using multilevel modeling with a sample of 171 employees nested in 40 workgroups, we found that transformational safety leadership strengthened the safety knowledge-participation relationship, whereas passive leadership weakened the safety motivation-participation relationship. Under low transformational leadership, safety motivation was not related to safety participation; under high passive leadership, safety knowledge was not related to safety participation. These results are discussed in light of organizational efforts to increase safety-related citizenship behaviors. Copyright © 2016 Elsevier Ltd and National Safety Council. All rights reserved.
Developing safety performance functions incorporating reliability-based risk measures.
Ibrahim, Shewkar El-Bassiouni; Sayed, Tarek
2011-11-01
Current geometric design guides provide deterministic standards where the safety margin of the design output is generally unknown and there is little knowledge of the safety implications of deviating from these standards. Several studies have advocated probabilistic geometric design where reliability analysis can be used to account for the uncertainty in the design parameters and to provide a risk measure of the implication of deviation from design standards. However, there is currently no link between measures of design reliability and the quantification of safety using collision frequency. The analysis presented in this paper attempts to bridge this gap by incorporating a reliability-based quantitative risk measure such as the probability of non-compliance (P(nc)) in safety performance functions (SPFs). Establishing this link will allow admitting reliability-based design into traditional benefit-cost analysis and should lead to a wider application of the reliability technique in road design. The present application is concerned with the design of horizontal curves, where the limit state function is defined in terms of the available (supply) and stopping (demand) sight distances. A comprehensive collision and geometric design database of two-lane rural highways is used to investigate the effect of the probability of non-compliance on safety. The reliability analysis was carried out using the First Order Reliability Method (FORM). Two Negative Binomial (NB) SPFs were developed to compare models with and without the reliability-based risk measures. It was found that models incorporating the P(nc) provided a better fit to the data set than the traditional (without risk) NB SPFs for total, injury and fatality (I+F) and property damage only (PDO) collisions.

Exploiting Science: Enhancing the Safety Training of Pilots to Reduce the Risk of Bird Strikes
NASA Astrophysics Data System (ADS)
Mendonca, Flavio A. C.
Analysis of bird strikes to aviation in the U.S. from 1990 to 2015 indicate that the successful mitigation efforts at airports, which must be sustained, have reduced incidents with damage and a negative effect-on-flight since 2000. However, such efforts have done little to reduce strikes outside the airport jurisdiction, such as occurred with US Airways Flight 1549 in 2009. There are basically three strategies to mitigate the risk of bird strikes: standards set by aviation authorities, technology, and actions by crewmembers. Pilots play an important role as stakeholders in the prevention of bird strikes, especially outside the airport environment. Thus, safety efforts require enhanced risk management and aeronautical decision-making training for flight crews. The purpose of this study was to determine if a safety training protocol could effectively enhance CFR Part 141 general aviation pilots' knowledge and skills to reduce the risk of bird strikes to aviation. Participants were recruited from the Purdue University professional flight program and from Purdue Aviation. The researcher of this study used a pretest posttest experimental design. Additionally, qualitative data were collected through open-ended questions in the pretest, posttest, and a follow-up survey questionnaire. The participants' pretest and posttest scores were analyzed using parametric and nonparametric tests. Results indicated a significant increase in the posttest scores of the experimental group. An investigation of qualitative data showed that the topic "safety management of bird hazards by pilots" is barely covered during the ground and flight training of pilots. Furthermore, qualitative data suggest a misperception of the safety culture tenets and a poor familiarity with the safety risk management process regarding bird hazards. Finally, the researcher presented recommendations for practice and future research.
Foundational workplace safety and health competencies for the emerging workforce.

Young workers (aged 15-24) suffer disproportionately from workplace injuries, with a nonfatal injury rate estimated to be two times higher than among workers age 25 or over. These workers make up approximately 9% of the U.S. workforce and studies have shown that nearly 80% of high school students work at some point during high school. Although young worker injuries are a pressing public health problem, the critical knowledge and skills needed to prepare youth for safe and healthy work are missing from most frameworks used to prepare the emerging U.S. workforce. A framework of foundational workplace safety and health knowledge and skills (the NIOSH 8 Core Competencies) was developed based on the Health Belief Model (HBM). The proposed NIOSH Core Competencies utilize the HBM to provide a framework for foundational workplace safety and health knowledge and skills. An examination of how these competencies and the HBM apply to actions that workers take to protect themselves is provided. The social and physical environments that influence these actions are also discussed. The NIOSH 8 Core Competencies, grounded in one of the most widely used health behavior theories, fill a critical gap in preparing the emerging U.S. workforce to be cognizant of workplace risks. Integration of the NIOSH 8 Core Competencies into school curricula is one way to ensure that every young person has the foundational workplace safety and health knowledge and skills to participate in, and benefit from, safe and healthy work.

Introduction Medical and public health societies advocate that healthcare providers (HCPs) counsel at-risk patients to reduce firearm injury risk. Anonymous online media comments often contain extreme viewpoints and may therefore help in understanding challenges of firearm safety counseling. To help inform injury prevention efforts, we sought to examine commenters’ stated opinions regarding firearm safety counseling HCPs. Methods Qualitative descriptive analysis of online comments posted following news items (in May–June, 2016) about a peer-reviewed publication addressing when and how HCPs should counsel patients regarding firearms. Results Among 871 comments posted by 522 individuals, most (57%) were generally negative toward firearm discussions, 17% were positive, and 26% were neutral/unclear. Two major categories and multiple themes emerged. “Areas of agreement” included that discussions may be valuable (1) when addressing risk of harm to self or others, (2) in pediatric injury prevention, and (3) as general safety education (without direct questioning), and that (4) HCPs lack gun safety and cultural knowledge. “Areas of tension” included whether (1) firearms are a public health issue, (2) counseling is effective prevention practice, (3) suicide could/should be prevented, and (4) firearm safety counseling is within HCPs’ purview. Conclusion Among this set of commenters with likely extreme viewpoints, opinions were generally negative toward firearm safety conversations, but with some support in specific situations. Providing education, counseling, or materials without asking about firearm ownership was encouraged. Engaging firearm advocates when developing materials may enhance the acceptability of prevention activities. PMID:28874943

Because of ongoing political and social instability throughout the continent, many Africans have become forced migrants. Unlike immigrants who choose to migrate, forced migrants flee their countries in search of safety and often endure multiple traumatic events during their migration. They are often unprepared for new risks in their adopted country. There is a high incidence of newly-diagnosed HIV cases among West African immigrants in the New York City metropolitan area, but little research to date to understand why this might occur. In order to gain insight, the current pilot study explored HIV knowledge, risk and protective behaviors among 52 West African-born forced migrants in New York City. HIV risk behavior came primarily from unprotected heterosexual activities. While most participants were very knowledgeable about HIV transmission and risk factors, almost half reported that they had not used condoms during sexual activities in the past 6 months. Women were more knowledgeable about HIV transmission, yet reported significantly more STDs than men. Many participants did not know about HIV/AIDS treatments and could not identify HIV/AIDS services and resources within their immigrant communities. Factors influencing HIV risk and protective behaviors among this population are identified and discussed. Suggestions for future research and strategies to reduce risky behaviors while enhancing protective ones among forced West African migrants are highlighted.

In addition to formaldehyde, workers in salons can be exposed to other chemical irritants, sensitizers, carcinogens, reproductive hazards, infectious agents, ergonomic, and other physical hazards. Worker health and safety training is challenging because of current product labeling practices and the myriad of hazards portending risk for a wide variety of health effects. Through a Susan B. Harwood Targeted Topic Training grant from the Occupational Safety and Health Administration and assistance from salon development and training partners, we developed, delivered, and validated a health and safety training program using an iterative five-pronged approach. The training was well received and resulted in knowledge gain, improved workplace safety practices, and increased communication about health and safety. These training materials are available for download from the Occupational Safety and Health Administration's Susan B. Harwood Training Grant Program Web site.

A growing body of literature analyzes farmer perceptions of pesticide risk, but much less attention has been given to differences in risk perception between farmers and technical experts. Furthermore, inconsistencies in knowledge have too easily been explained in terms of lack of knowledge rather than exploring the underlying reasons for particular forms of thinking about pesticide risks. By doing this, the division between expert and lay knowledge has been deepened rather than transcended. Objective: This study aims to understand differences and similarities among the perceptions of pesticide risks of farmers, farm workers, and technical experts such as extensionists, by applyingmore » a social science approach towards knowledge and risk attitudes. Methods: Semi-structured interviews and field observations were conducted to smallholders, farm workers, extensionists, health professionals and scientists involved in the use and handling of pesticides. Subsequently, a survey was carried out to quantify the farmers and extensionists' acceptance or rejection of typical assertions expressed previously in the semi-structured interviews. Results: Smallholders showed to gain knowledge from their own experiences and to adapt pesticides practices, which is a potential basis for transforming notions of pesticide safety and risk reduction strategies. Though extensionists have received formal education, they sometimes develop ideas deviating from the technical perspective. The risk perception of the studied actors appeared to vary according to their role in the agricultural labor process; they varied much less than expected according to their schooling level. Conclusions: Commitment to the technical perspective is not dramatically different for extensionists on the one hand and farmers as well as farm workers on the other hand. Ideas about a supposed lack of knowledge by farmers and the need of formal training are too much driven by a deficit model of knowledge. Further research on risk perceptions of pesticides and training of rural people will benefit from the development of a knowledge-in-context model. -- Highlights: • Researching perceptions of farmers' extensionists and other professionals. • Experts as well as farmers deviate from the technical perspective. • Blaming who is responsible for pesticide problems creates expert-lay division. • Qualitative and quantitative methods, not as complementary but integrated. • Knowledge-in-context model as an alternative to the knowledge-deficit model.« less

Skiing and snowboarding are leading to a risk of injuries in children. Beginners and experienced have higher risk of injuries, however, the first have less severe injuries than the latest. Risk factors of injury are: ability and experience, binding adjustment, slope characteristics, speed, collisions with objects or jumping and risky behavior of the young skiers and snowboarders. Lower limb injuries are most common in skier, especially knee sprains, conversely snowboarders present more upper limb injuries, especially wrist fractures. The frequency of head injuries does not decrease while helmet use increases but severity decreases. Despite prevention and wearing protections, the frequency of trauma does not decrease significantly, which could be in relation with higher speed and increased risky behavior. Main prevention factors are safety knowledge and safety behavior, correct binding adjustment, and use of protections.

Several earlier studies have noted the shortcomings with existing geometric design guides which provide deterministic standards. In these standards the safety margin of the design output is generally unknown and there is little knowledge of the safety implications of deviating from the standards. To mitigate these shortcomings, probabilistic geometric design has been advocated where reliability analysis can be used to account for the uncertainty in the design parameters and to provide a mechanism for risk measurement to evaluate the safety impact of deviations from design standards. This paper applies reliability analysis for optimizing the safety of highway cross-sections. The paper presents an original methodology to select a suitable combination of cross-section elements with restricted sight distance to result in reduced collisions and consistent risk levels. The purpose of this optimization method is to provide designers with a proactive approach to the design of cross-section elements in order to (i) minimize the risk associated with restricted sight distance, (ii) balance the risk across the two carriageways of the highway, and (iii) reduce the expected collision frequency. A case study involving nine cross-sections that are parts of two major highway developments in British Columbia, Canada, was presented. The results showed that an additional reduction in collisions can be realized by incorporating the reliability component, P(nc) (denoting the probability of non-compliance), in the optimization process. The proposed approach results in reduced and consistent risk levels for both travel directions in addition to further collision reductions. Copyright © 2012 Elsevier Ltd. All rights reserved.
Food safety practices among Norwegian consumers.

An informed consumer can compensate for several potential food safety violations or contaminations that may occur earlier in the food production chain. However, a consumer can also destroy the work of others in the chain by poor food handling practices, e.g., by storing chilled ready-to-eat foods at abusive temperatures. To target risk-reducing strategies, consumer groups with high-risk behavior should be identified. The aim of this study was to identify demographic characteristics associated with high-risk food handling practices among Norwegian consumers. More than 2,000 randomly selected Norwegian consumers were surveyed, and the results were analyzed with a risk-based grading system, awarding demerit points for self-reported food safety violations. The violations were categorized into groups, and an ordinary multiple linear regression analysis was run on the summarized demerit score for each group and for the entire survey group as a whole. Young and elderly men were identified as the least informed consumer groups with the most unsafe practices regarding food safety. Single persons reported poorer practices than those in a relationship. People with higher education reported poorer practices than those with lower or no education, and those living in the capital of Norway (Oslo) reported following more unsafe food practices than people living elsewhere in Norway. Men reported poorer food safety practices than women in all categories with two exceptions: parboiling raw vegetables before consumption and knowledge of refrigerator temperature. These findings suggest that risk-reducing measures should target men, and a strategy is needed to change their behavior and attitudes.

Tunneling excavation is bound to produce significant disturbances to surrounding environments, and the tunnel-induced damage to adjacent underground buried pipelines is of considerable importance for geotechnical practice. A fuzzy Bayesian networks (FBNs) based approach for safety risk analysis is developed in this article with detailed step-by-step procedures, consisting of risk mechanism analysis, the FBN model establishment, fuzzification, FBN-based inference, defuzzification, and decision making. In accordance with the failure mechanism analysis, a tunnel-induced pipeline damage model is proposed to reveal the cause-effect relationships between the pipeline damage and its influential variables. In terms of the fuzzification process, an expert confidence indicator is proposed to reveal the reliability of the data when determining the fuzzy probability of occurrence of basic events, with both the judgment ability level and the subjectivity reliability level taken into account. By means of the fuzzy Bayesian inference, the approach proposed in this article is capable of calculating the probability distribution of potential safety risks and identifying the most likely potential causes of accidents under both prior knowledge and given evidence circumstances. A case concerning the safety analysis of underground buried pipelines adjacent to the construction of the Wuhan Yangtze River Tunnel is presented. The results demonstrate the feasibility of the proposed FBN approach and its application potential. The proposed approach can be used as a decision tool to provide support for safety assurance and management in tunnel construction, and thus increase the likelihood of a successful project in a complex project environment. © 2015 Society for Risk Analysis.

Unsafe behavior increases the risk of accident at workplaces and needs to be managed properly. The aim of the present study was to provide a model for managing and improving safety behavior of employees using the Bayesian networks approach. The study was conducted in several power plant construction projects in Iran. The data were collected using a questionnaire composed of nine factors, including management commitment, supporting environment, safety management system, employees' participation, safety knowledge, safety attitude, motivation, resource allocation, and work pressure. In order for measuring the score of each factor assigned by a responder, a measurement model was constructed for each of them. The Bayesian network was constructed using experts' opinions and Dempster-Shafer theory. Using belief updating, the best intervention strategies for improving safety behavior also were selected. The result of the present study demonstrated that the majority of employees do not tend to consider safety rules, regulation, procedures and norms in their behavior at the workplace. Safety attitude, safety knowledge, and supporting environment were the best predictor of safety behavior. Moreover, it was determined that instantaneous improvement of supporting environment and employee participation is the best strategy to reach a high proportion of safety behavior at the workplace. The lack of a comprehensive model that can be used for explaining safety behavior was one of the most problematic issues of the study. Furthermore, it can be concluded that belief updating is a unique feature of Bayesian networks that is very useful in comparing various intervention strategies and selecting the best one form them.

The Institute of Medicine has recommended a change in culture from "name and blame" to patient safety. This will require system redesign to identify and address errors, establish performance standards, and set safety expectations. This approach, however, is at odds with the present medical malpractice (tort) system. The current system is outcomes-based, meaning that health care providers and institutions are often sued despite providing appropriate care. Nevertheless, the focus should remain to provide the safest patient care. Effective peer review may be hindered by the present tort system. Reporting of medical errors is a key piece of peer review and education, and both anonymous reporting and confidential reporting of errors have potential disadvantages. Diagnostic and treatment errors continue to be the leading sources of allegations of malpractice in pediatrics, and the neonatal intensive care unit is uniquely vulnerable. Most errors result from systems failures rather than human error. Risk management can be an effective process to identify, evaluate, and address problems that may injure patients, lead to malpractice claims, and result in financial losses. Risk management identifies risk or potential risk, calculates the probability of an adverse event arising from a risk, estimates the impact of the adverse event, and attempts to control the risk. Implementation of a successful risk management program requires a positive attitude, sufficient knowledge base, and a commitment to improvement. Transparency in the disclosure of medical errors and a strategy of prospective risk management in dealing with medical errors may result in a substantial reduction in medical malpractice lawsuits, lower litigation costs, and a more safety-conscious environment.

Risk management of lasers can be broadly define das a process of identification of the risk, assessment of the risk and steps taken to avert the risk. The risk management may be divided into: Risk inherent to the technology and risk in clinical use. Within the National Health Service in the UK, a useful document, which provides hospital laser users with advice on safety, is the 'Guidance on the Safe Use of Lasers in Medical and Dental Practice' issued by the Medical Devices Agency for the Department of Health in the UK. It recommends the appointment of a Laser Protection Adviser (LPA) who is knowledgeable in the evaluation of laser hazards. One of the duties LPA is to ensure that Local Rules are drawn up for each specific application of a laser. A Laser Protection Supervisor (LPS) should also be appointed with responsibility to ensure that the Local Rules are observed. It is a sensible precaution that laser users should be those approved by the Laser Protection Supervisor in consultation with the Laser Protection Advisor. All laser users should sign a statement that they have read and understood the Local Rules.

To investigate African-American parental reasons for pacifier use or non-use, and whether knowledge of the association with decreased SIDS risk changes decisions about pacifier use. We conducted focus groups and individual interviews with mothers. Grounded theory methodology was used. 83 mothers participated; 72.3 % of infants used pacifiers. Reasons for pacifier use included comfort/soothing, safety/SIDS, and preference over digit-sucking. Reasons for pacifier non-use included infant refusal, fear of attachment, nipple confusion, and germs. Many parents were unaware that pacifier use reduces SIDS risk; however, most parents of non-users did not think that this knowledge would have changed their decision. Reasons included skepticism about the pacifier-SIDS link. Many reasons underlie African-American parental decisions about pacifier use. Providers should provide information about the benefits of pacifiers. Establishing for parents any plausible link between the protective mechanism of pacifiers and SIDS pathophysiology may be important in promoting pacifier use.
Industrial requirements in food safety.
Vincent, P M
1990-01-01
The principles of establishing industrial requirements in food safety are described, taking risk potentials all along the food chain into their respective account. Regulations will, in the future, lead to increased autocontrol in production. The rapid changes in food technology require constant adaptation to new problems, to keep the global quality of food at a high level. Regulatory authorities will, in the new European market, concentrate on enforcement of 'essential requirements' while industrialists will follow good manufacturing practices. Open dialogue between the latter, the former and the scientific community is highly desirable since mutual knowledge of the problem will help maintain a high level of food safety, for the benefit of everybody.

Dog bites represent a significant threat to child health. Theory-driven interventions scalable for broad dissemination are sparse. A website was developed to teach children dog safety via increased knowledge, improved cognitive skills in relevant domains, and increased perception of vulnerability to bites. A randomized controlled trial was conducted with 69 children aged 4–5 randomly assigned to use the dog safety website or a control transportation safety website for ~3 weeks. Assessment of dog safety knowledge and behavior plus skill in three relevant cognitive constructs (impulse control, noticing details, and perspective-taking) was conducted both at baseline and following website use. The dog safety website incorporated interactive games, instructional videos including testimonials, a motivational rewards system, and messaging to parents concerning child lessons. Our results showed that about two-thirds of the intervention sample was not adherent to website use at home, so both intent-to-treat and per-protocol analyses were conducted. Intent-to-treat analyses yielded mostly null results. Per-protocol analyses suggested children compliant to the intervention protocol scored higher on knowledge and recognition of safe behavior with dogs following the intervention compared to the control group. Adherent children also had improved scores post-intervention on the cognitive skill of noticing details compared to the control group. We concluded that young children’s immature cognition can lead to dog bites. Interactive eHealth training on websites shows potential to teach children relevant cognitive and safety skills to reduce risk. Compliance to website use is a challenge, and some relevant cognitive skills (e.g., noticing details) may be more amenable to computer-based training than others (e.g., impulse control).

Young people are at an increased risk for illness in working life. The authorities stipulate certain goals for training in occupational health and safety (OHS) in vocational schools. A previous study concluded that pupils in vocational education had limited knowledge in the prevention of health risks at work. The aim of the current study, therefore, was to study how OHS training is organized in school and in workplace-based learning (WPL). The study design featured a qualitative approach, which included interviews with 12 headmasters, 20 teachers, and 20 supervisors at companies in which the pupils had their WPL. The study was conducted at 10 upper secondary schools, located in Central Sweden, that were graduating pupils in four vocational programs. The interviews with headmasters, teachers, and supervisors indicate a staggered picture of how pupils are prepared for safe work. The headmasters generally give teachers the responsibility for how goals should be reached. Teaching is very much based on risk factors that are present in the workshops and on teachers' own experiences and knowledge. The teaching during WPL also lacks the systematic training in OHS as well as in the traditional classroom environment. Teachers and supervisors did not plan the training in OHS in accordance with the provisions of systematic work environment management. Instead, the teachers based the training on their own experiences. Most of the supervisors did not receive information from the schools as to what should be included when introducing OHS issues in WPL.
The role of Indigenous knowledge in environmental health risk management in Yukon, Canada
Friendship, Katelyn A.; Furgal, Chris M.
2012-01-01
Objectives This project aimed to gain better understandings of northern Indigenous risk perception related to food safety and to identify the role that Indigenous knowledge (IK) plays in risk management processes to support more effective and culturally relevant benefit-risk (B-R) management strategies. Study design The project used an exploratory qualitative case study design to investigate the role and place of IK in the management of environmental contaminants exposure via consumption of traditional foods in Yukon First Nations (YFNs). Methods Forty-one semi-directive interviews with Traditional Food Knowledge Holders and Health and Environment Decision-makers were conducted. A review and analysis of organizational documents related to past risk management events for the issue was conducted. Thematic content analysis was used to analyze transcripts and documents for key themes related to the research question. Results There was a recognized need by all participants for better collaboration between scientists and YFN communities. YFNs have been involved in identifying and defining community concerns about past risk issues, setting a local context, and participating in communications strategies. Interviewees stressed the need to commit adequate time for building relationships, physically being in the community, and facilitating open communication. Conducting community-based projects was identified as critical for collaboration and for cooperative learning and management of these issues. Conclusions The perception of “effective” benefit-risk management is significantly influenced by the efforts made to include local communities in the process. A set of common guiding principles within a process that brings together people and knowledge systems may provide a more effective way forward in cross-cultural, multiple knowledge system contexts for complex benefit-risk issues than a prescriptive rigid framework.

Major accident prevention through applying safety knowledge management approach.
Kalatpour, Omid
2016-01-01
Many scattered resources of knowledge are available to use for chemical accident prevention purposes. The common approach to management process safety, including using databases and referring to the available knowledge has some drawbacks. The main goal of this article was to devise a new emerged knowledge base (KB) for the chemical accident prevention domain. The scattered sources of safety knowledge were identified and scanned. Then, the collected knowledge was formalized through a computerized program. The Protégé software was used to formalize and represent the stored safety knowledge. The domain knowledge retrieved as well as data and information. This optimized approach improved safety and health knowledge management (KM) process and resolved some typical problems in the KM process. Upgrading the traditional resources of safety databases into the KBs can improve the interaction between the users and knowledge repository.

Modified vaccinia virus Ankara (MVA) is the vector of choice for human and veterinary applications due to its strong safety profile and immunogenicity in vivo. The use of MVA and MVA-vectored vaccines against human and animal diseases must comply with regulatory requirements as they pertain to environmental risk assessment, particularly the characterization of potential adverse effects to humans, animals and the environment. MVA and recombinant MVA are widely believed to pose low or negligible risk to ecosystem health. However, key aspects of MVA biology require further research in order to provide data needed to evaluate the potential risks that may occur due to the use of MVA and MVA-vectored vaccines. The purpose of this paper is to identify knowledge gaps in the biology of MVA and recombinant MVA that are of relevance to its hazard characterization and discuss ongoing and future experiments aimed at providing data necessary to fill in the knowledge gaps. In addition, we presented arguments for the inclusion of uncertainty analysis and experimental investigation of verifiable worst-case scenarios in the environmental risk assessment of MVA and recombinant MVA. These will contribute to improved risk assessment of MVA and recombinant MVA vaccines. PMID:29109380

Modified vaccinia virus Ankara (MVA) is the vector of choice for human and veterinary applications due to its strong safety profile and immunogenicity in vivo. The use of MVA and MVA-vectored vaccines against human and animal diseases must comply with regulatory requirements as they pertain to environmental risk assessment, particularly the characterization of potential adverse effects to humans, animals and the environment. MVA and recombinant MVA are widely believed to pose low or negligible risk to ecosystem health. However, key aspects of MVA biology require further research in order to provide data needed to evaluate the potential risks that may occur due to the use of MVA and MVA-vectored vaccines. The purpose of this paper is to identify knowledge gaps in the biology of MVA and recombinant MVA that are of relevance to its hazard characterization and discuss ongoing and future experiments aimed at providing data necessary to fill in the knowledge gaps. In addition, we presented arguments for the inclusion of uncertainty analysis and experimental investigation of verifiable worst-case scenarios in the environmental risk assessment of MVA and recombinant MVA. These will contribute to improved risk assessment of MVA and recombinant MVA vaccines.

Based on the advance of toxicology and related sciences, a regulatory regime for the safety of chemicals related to daily life has been rapidly established. Especially for the food-related substances, the process of risk analysis has facilitated the collaboration by all the players including consumers toward the security of their safety. On the other hand, except for pharmaceuticals, science-based decisions and governmental actions on safety issues have not always gained confidence of the public. One of the reasons was the inadequacy in the way of use of scientific knowledge, or in other words, inappropriateness of decision making by "the regulatory science". Regulatory science is a science to warrant the decision making processes for governmental acts (Mitsuru Uchiyama). In the case of chemical safety, it can be redefined as a theoretical concept to complements the uncertainty of scientific knowledge for the decision of governmental acts that is adequate in both scientific and social ways. Therefore, the regulatory science is an indispensable discipline to effectively apply risk analysis. Here, the significance of the regulatory science for the hazard assessment of the chemicals, especially for children is described. In the past, the hazard effects of chemicals have been assessed for adults. Recently, however, the importance of the assessment for children has gained international emphases. Not only for pharmaceuticals, but for food-related substances, the acceptable daily intake (ADI) and tolerable daily intake (TDI) are often set differently for adults and children. The child-specific responses against chemicals are related not only to the physiological factors such as body weight, basal metabolism, but also rapid growth of the body with developmental status of various organs. General knowledge on these issues will be discussed mainly referring the World Health Organization (WHO) documents. Although the cutting edge technology backs up the development of toxicology, it would appear that it is reaching a turning point from technology-centrism to look toward the direction for contribution to society from the stand point of regulatory science.

Food handler's knowledge, attitude and practice regarding food allergies are important to prevent debilitating and sometimes fatal reactions. This study aimed to assess their food allergy knowledge, attitude and practice, which could help to maintain the safety and hygiene of food consumed by the public. Cross-sectional survey. A cross-sectional survey involving 121 conveniently sampled (81.76% response rate) respondents among the food handlers in the state of Penang, Malaysia, was conducted using a validated self-administered questionnaire. Their knowledge, attitude and work practice were captured using a 37-item questionnaire that elicited their responses using a mixture of closed-ended and Likert scale techniques. The mean knowledge score for respondents was 50.23 (SD = 14.03), attitude score was 54.26 (SD = 11.67) and practice score was 45.90 (SD = 24.78). Only 1.79% of the respondents were considered to have excellent knowledge, 21.37% had a low risk practice and 4.27% had positive attitudes towards food allergies. Most of the respondents (70%) knew about food allergies and their seriousness. There was a statistically significant correlation between the attitude and practice of respondents (r = 0.51). The type of establishment was the only characteristic significantly associated (P < 0.05) with food handler allergy knowledge, attitude and practice. More than half of food handlers in Penang have moderate levels of food allergy knowledge, practice and attitude. Only a small proportion of them have excellent food allergy knowledge, practice and attitude. Integration of food allergy training into compulsory food safety training programmes is needed to reduce food allergy risks and prevent fatal allergic reactions to food among their customers.

To study the association between knowledge about levonorgestrel emergency contraception (LNG-EC) and the risk of ectopic pregnancy (EP) following LNG-EC failure. This study included 600 women who had visited the hospital with LNG-EC failure. Of these, 300 with EP and 300 with intrauterine pregnancy (IUP) were recruited to the EP group and IUP group respectively. The participants were interviewed face-to-face using a standardized questionnaire. Pearson's chi-square tests and t-test were used to compare the sociodemographic characteristics, reproductive and gynecological history, surgical history, previous contraceptive experience, and answers to 10 questions concerning the knowledge about LNG-EC. Those who gave incorrect answers to the question regarding the basic mechanism and specific method of levonorgestrel emergency contraceptive pills (LNG-ECPs) were at a higher risk of EP after LNG-EC failure. Women who did not strictly follow instructions or advice from healthcare professionals were more likely to subsequently experience EP (p < 10(-4) ). Women with LNG-EC failure reported friends/peers, TV, and Internet as the main sources of information. No difference was observed with regard to the sources of knowledge on LNG-EC (p = 0.07). The results illustrate the importance of strictly following the doctor's guidance or drug instructions when using LNG-ECPs. The media should be used to disseminate information about responsible EC, and pharmacy staff should receive regular educational training sessions in this regard. © 2016 The Authors.

Following the adoption of the ICH E2E guideline, risk management plans (RMP) defining the cumulative safety experience and identifying limitations in safety information are now required for marketing authorisation applications (MAA). A collaborative research project was conducted to gain experience with tools for presenting and evaluating data in the safety specification. This paper presents those tools found to be useful and the lessons learned from their use. Archive data from a successful MAA were utilised. Methods were assessed for demonstrating the extent of clinical safety experience, evaluating the sensitivity of the clinical trial data to detect treatment differences and identifying safety signals from adverse event and laboratory data to define the extent of safety knowledge with the drug. The extent of clinical safety experience was demonstrated by plots of patient exposure over time. Adverse event data were presented using dot plots, which display the percentages of patients with the events of interest, the odds ratio, and 95% confidence interval. Power and confidence interval plots were utilised for evaluating the sensitivity of the clinical database to detect treatment differences. Box and whisker plots were used to display laboratory data. This project enabled us to identify new evidence-based methods for presenting and evaluating clinical safety data. These methods represent an advance in the way safety data from clinical trials can be analysed and presented. This project emphasises the importance of early and comprehensive planning of the safety package, including evaluation of the use of epidemiology data.

Emergency medical services (EMS) personnel care for patients in challenging and dynamic environments that may contribute to an increased risk for adverse events. However, little is known about the risks to patient safety in the EMS setting. To address this knowledge gap, we conducted a systematic review of the literature, including nonrandomized, noncontrolled studies, conducted qualitative interviews of key informants, and, with the assistance of a pan-Canadian advisory board, hosted a 1-day summit of 52 experts in the field of EMS patient safety. The intent of the summit was to review available research, discuss the issues affecting prehospital patient safety, and discuss interventions that might improve the safety of the EMS industry. The primary objective was to define the strategic goals for improving patient safety in EMS. Participants represented all geographic regions of Canada and included administrators, educators, physicians, researchers, and patient safety experts. Data were collected through electronic voting and qualitative analysis of the discussions. The group reached consensus on nine recommendations to increase awareness, reduce adverse events, and suggest research and educational directions in EMS patient safety: increasing awareness of patient safety principles, improving adverse event reporting through creating nonpunitive reporting systems, supporting paramedic clinical decision making through improved research and education, policy changes, using flexible algorithms, adopting patient safety strategies from other disciplines, increasing funding for research in patient safety, salary support for paramedic researchers, and access to graduate training in prehospital research.

The results from the first survey on food safety knowledge, attitudes and hygiene practices (KAP) among veterinary medicine students in Bulgaria are reported in this study. It was designed and conducted from September to December 2015 using structured questionnaires on food safety knowledge, attitudes and practices. Data were collected from 100 undergraduate veterinary medicine students from the Trakia University, Bulgaria. It was observed that the age and the gender did not affect food safety knowledge, attitudes and practices. There was no significant difference (p>0.05) on food safety knowledge and practices among students based on the years of study. A high level of food safety knowledge was observed among the participants (85.06%), however, the practice of food safety was above average (65.28%) while attitude toward food safety was high (70%). Although there was a significant awareness of food safety knowledge among respondents, there is a need for improvement on food safety practices, interventions on food safety and foodborne diseases.

[Novel technologies in the food and agriculture industry].
de Vogel, P
1992-11-01
Product innovation obtained by means of new processes or novel raw materials or ingredients is not a recent event. The consumer today has access to a large array of products from which he may compose a nutritionally balanced diet with no inherent questions regarding food safety or wholesomeness. The controversial opinions of the consumer with regard to certain new technologies applied to food should not be confounded with the possible existence of a related unacceptable risk of the corresponding products. Scientific knowledge, from which such technologies are the result, provides a solid basis for the establishment of food safety. The principle of risk assessment should be applied by the manufacturer whenever innovative technologies are introduced in the creation of new food products.
The role and functionality of Veterinary Services in food safety throughout the food chain.
McKenzie, A I; Hathaway, S C
2006-08-01
Both national Veterinary Services and international standard-setting organisations have now embraced risk assessment as an essential tool for achieving their goals. Veterinarians have key roles in all aspects of the control of food-borne hazards of animal origin, but additional specialist skills are necessary for assessing, managing and communicating risk. Further, the deployment of Veterinary Services must reflect the multi-functional aspects of public and animal health activities. A generic risk management framework provides a systematic process whereby food safety standards and other measures are chosen and implemented on the basis of knowledge of risk and evaluation of other factors relevant to protecting human health and promoting non-discriminatory trade practices. In this context, a number of countries are exploring new administrative and structural arrangements for competent authorities. The traditional focus of veterinary involvement in food safety has been in meat hygiene at the level of the slaughterhouse. While this role continues, the emerging 'risk-based' approach to food control requires increased involvement in other segments of the meat food chain, as well as other areas such as production of milk and fish. This more extensive role requires a wider skill base and establishment of effective networks with a different range of stakeholders.

The use of nanotechnology and advanced materials promises to revolutionise many areas of technology and improve our daily life. In that respect, many positive effects on the environment are expected, either directly, by developing new technologies for remediation, filtering techniques or energy generation, or indirectly, by e.g. saving resources due to lower consumption of raw materials, or lower energy and fuel consumption due to reduced weight of vehicles. However, such beneficial effects of new technologies are often confronted by concerns regarding the safety of novel substances or materials. During the past 10 years, great effort has been put into research on potential hazards of nanomaterials towards environmental organisms. As the methodology for reliable assessment of nanomaterials was immature, many studies reporting contradictory results have been published, hindering both risk assessment for nanomaterials, as well as the knowledge communication to all involved stakeholders. Thus, DaNa 2.0 serves as a platform to implement trusted knowledge on nanomaterials for an objective discussion.
Thyroidectomy: post-operative care and common complications.
Furtado, L
Any surgical procedure involves risks. Thyroid surgery can cause potentially fatal complications during the early post-operative phase. It is essential that nurses have the knowledge and skills to detect early signs and symptoms of potential complications and take appropriate action. Early detection and rapid response are key to maintaining patient safety and minimising harm.

Foodborne illnesses pose a problem to all individuals but are especially significant for infants, the elderly, and individuals with compromised immune systems. Personal hygiene is recognized as the number-one way people can lower their risk. The majority of meals in the U.S. are eaten at home. Little is known, however, about the actual application of personal hygiene and sanitation behaviors in the home. The study discussed in this article assessed knowledge of hygiene practices compared to observed behaviors and determined whether knowledge equated to practice. It was a descriptive study involving a convenience sample of 30 households. Subjects were recruited from the Boston area and a researcher and/or a research assistant traveled to the homes of study participants to videotape a standard food preparation procedure preceded by floor mopping. The results highlight the differences between individuals' reported beliefs and actual practice. This information can aid food safety and other health professionals in targeting food safety education so that consumers understand their own critical role in decreasing their risk for foodborne illness.
Early warnings, weak signals and learning from healthcare disasters.
Macrae, Carl
2014-06-01
In the wake of healthcare disasters, such as the appalling failures of care uncovered in Mid Staffordshire, inquiries and investigations often point to a litany of early warnings and weak signals that were missed, misunderstood or discounted by the professionals and organisations charged with monitoring the safety and quality of care. Some of the most urgent challenges facing those responsible for improving and regulating patient safety are therefore how to identify, interpret, integrate and act on the early warnings and weak signals of emerging risks-before those risks contribute to a disastrous failure of care. These challenges are fundamentally organisational and cultural: they relate to what information is routinely noticed, communicated and attended to within and between healthcare organisations-and, most critically, what is assumed and ignored. Analysing these organisational and cultural challenges suggests three practical ways that healthcare organisations and their regulators can improve safety and address emerging risks. First, engage in practices that actively produce and amplify fleeting signs of ignorance. Second, work to continually define and update a set of specific fears of failure. And third, routinely uncover and publicly circulate knowledge on the sources of systemic risks to patient safety and the improvements required to address them.

Persons with human immunodeficiency virus (HIV) risk behaviors are excluded from donation to reduce the risk of transfusion-transmitted infection. Persons donating to be tested for HIV may therefore deny risk behaviors. A random sample of donors completed a survey on motivations, knowledge, and attitudes on the screening process. Donors were considered test seekers if they agreed with two statements "I think that blood donation is a good, fast, and anonymous way to get my blood tested" and "I donate to get my test results." This study was conducted from June to November 2006 at the largest blood bank in São Paulo, Brazil. Of 3061 participants, 208 (7%) were test seekers. They tended to be male and had a lower educational level. They were more likely to have incorrect knowledge about blood safety (e.g., not knowing that a unit can test antibody negative and still transmit infection, 50% vs. 42%, p = 0.02), express dissatisfaction with screening questions (e.g., feeling that important questions were not asked, 14% vs. 5%, p < 0.01), and concur that donors do not answer questions truthfully (e.g., donors have more sexual partners than they admit, 29% vs. 18%, p < 0.01). Test seekers were more likely to believe that it is acceptable to donate blood to get tested for HIV (41% vs. 10%, p < 0.01). Test-seeking motivation, coupled with low knowledge of window period risk, is counter to improving blood safety and to donor prevention needs. Donor education needs to be improved along with availability of appropriate HIV counseling and testing. © 2010 American Association of Blood Banks.

One of NASA's goals for long duration space flight is to maintain acceptable levels of crew health, safety, and performance. One way of meeting this goal is through the Biomedical Risk Assessment Intelligent Network (BRAIN), an integrated network of both human and computer elements. The BRAIN will function as an advisor to flight surgeons by assessing the risk of in-flight biomedical problems and recommending appropriate countermeasures. This paper describes the joint effort among various NASA elements to develop BRAIN and an Infectious Disease Risk Assessment (IDRA) prototype. The implementation of this effort addresses the technological aspects of the following: (1) knowledge acquisition; (2) integration of IDRA components; (3) use of expert systems to automate the biomedical prediction process; (4) development of a user-friendly interface; and (5) integration of the IDRA prototype and Exercise Countermeasures Intelligent System (ExerCISys). Because the C Language, CLIPS (the C Language Integrated Production System), and the X-Window System were portable and easily integrated, they were chosen as the tools for the initial IDRA prototype. The feasibility was tested by developing an IDRA prototype that predicts the individual risk of influenza. The application of knowledge-based systems to risk assessment is of great market value to the medical technology industry.
Prevention of MSD within OHSMS/IMS: a systematic review of risk assessment strategies.
Yazdani, Amin; Wells, Richard
2012-01-01
The purpose of this systematic review was to identify and summarize the research evidence on prevention of Musculoskeletal Disorders (MSD) within Occupational Health and Safety Management Systems (OHSMS) and Integrated Management Systems (IMS). Databases in business, management, engineering and health and safety were systematically searched and relevant publications were synthesized. The number of papers that could address the research questions was small. However, the review revealed that many of the techniques to address MSD hazards require substantial background knowledge and training. This may limit employees' involvement in the technical aspects of the risk assessment process. Also these techniques did not usually fit into techniques used by companies to address other risk factors within their management systems. This could result in MSD prevention becoming a separate issue that cannot be managed with company-wide tools. In addition, this review also suggested that there is a research gap concerning the MSD prevention within companies' management systems.
Managing safety and quality through the red meat chain.
Desmarchelier, P; Fegan, N; Smale, N; Small, A
2007-09-01
To successfully manage food safety and quality risks in meat production, a holistic approach is required. The ideal would be a fully integrated assurance system, with effective controls applied at all stages. However, the red meat industry is by nature somewhat fragmented, and a truly integrated system is not at present achievable in all but a few operations. This paper describes a variety of assurance initiatives, and explores how targeted research and development can be used to augment assurance programmes by providing underpinning knowledge, using the Australian beef and lamb industry as an example.

The unsafe and indiscriminate use of pesticides in agriculture represents a major hazard to the environment and human health. The aim of this study was to assess the levels of knowledge, attitude and practices of Kuwaiti farmers regarding the safe use of pesticides. A total of 250 farmers participated in this study through in-depth interviews and observations on-farm. The majority of the farmers acknowledged that pesticides were harmful to their health (71%) and the environment (65%). However, farmers' level of knowledge of pesticide safety is insufficient. Over 70% of the farmers did not read or follow pesticide label instructions, and 58% did not use any personal protective equipment (PPE) when handling pesticides. Educated farmers were significantly more likely to use PPE compared with famers with limited formal education (χ² = 9.89, p < 0.05). Storage of pesticides within living areas was reported by 20% of farmers. When disposing of pesticide wastes, respondents adopted unsafe practices such as discarding, incinerating, or burying empty pesticide containers on-farm, or reusing the containers. Farmers also reported disposing leftover pesticide solution or old pesticide stocks on-farm or in the sewer. A significant number (82%) of the farmers reported at least one symptom of acute pesticide poisoning. Although farmers' knowledge of pesticide hazards was high, the reported safety measures were poor. Comprehensive intervention measures to reduce the health and environmental risks of pesticides are needed, including pesticide safety training programs for farmers, stringent enforcement of pesticide laws, and promoting integrated pest management and non-synthetic methods of pest control.

Prenatal knowledge and informational priorities of pregnant adolescents.
Smith, P B; Levenson, P M; Morrow, J R
1985-01-01
One hundred and forty-six indigent pregnant adolescents (12 to 18 years of age) were asked to complete a questionnaire concerning their prenatal care priorities (Scale I) and their knowledge of correct perinatal behaviors (Scale II). On Scale I, over 75% of teens considered parenting skills, infant care, and diet extremely important. On Scale II correctly answered items focused on the need to avoid substance abuse and smoking during pregnancy, visit the doctor, and eat balanced meals. The mean number of correct answers, however, was only 11.8 out of a total possible scale of 18 items. Less than 50% correctly answered statements about the effects of weight gain and other health behaviors on risk for high blood pressure and toxemia, safety of laxatives during pregnancy, possibility of becoming pregnant again before resuming menstruation, and the safety of various physical activities. Performance on both knowledge and health priority scales showed correct health information was limited to basic concrete facts. Abstract and technical aspects of health care did not appear to be easily assimilated.

2010-07-01
This study's purpose was to assess knowledge and concerns related to the human papillomavirus (HPV) vaccine among underserved Latina women and Latina mothers of female adolescents and to explore differences between those in the vaccinated and those in the unvaccinated groups. We conducted cross-sectional written surveys of 206 Latina women at an urban health center in central New Jersey. Participants included vaccine-eligible women and mothers of vaccine-eligible adolescents. We calculated descriptive statistics, Fisher exact tests, and corresponding risk ratios (RRs) with 95% CIs. Of those who had heard of HPV (71%), 80% knew that HPV is a sexually transmitted infection. Fewer understood the causative link between HPV and cervical cancer (58%) and genital warts (45%). Vaccine safety was the most frequently cited concern. Unvaccinated women and mothers of unvaccinated daughters were more worried that the vaccine could promote risky sexual behavior (RR = 1.6, 95% CI = 1.2-2.1) and more likely to believe that they or their daughters were not at risk for HPV infection (RR = 1.2, 95% CI = 1.1-1.4). To maximize HPV vaccination rates among underserved Latinas, concerns about vaccine safety, potential effects on sexual behavior, and self-perceptions of risk for HPV infection must be addressed.

Developing safe and effective medical devices involves understanding the hazardous situations that can arise in clinical practice and implementing appropriate risk control measures. The hazardous situations may have their roots in the design or in the use of the device. Risk control measures may be engineering or clinically based. A multidisciplinary team of engineers and clinicians is needed to fully identify and assess the risks and implement and evaluate the effectiveness of the control measures. In this paper, I use three issues, calibration/accuracy, response time, and protective measures/alarms, to highlight the contributions of these groups. This important information is captured in standards and regulatory tools to control risk for respiratory gas monitors and pulse oximeters. This paper begins with a discussion of the framework of safety, explaining how voluntary standards and regulatory tools work. The discussion is followed by an examination of how engineering and clinical knowledge are used to support the assurance of safety.
Accident frequency and unrealistic optimism: Children's assessment of risk.
Joshi, Mary Sissons; Maclean, Morag; Stevens, Claire
2018-02-01
Accidental injury is a major cause of mortality and morbidity among children, warranting research on their risk perceptions. Three hundred and seven children aged 10-11 years assessed the frequency, danger and personal risk likelihood of 8 accidents. Two social-cognitive biases were manifested. The frequency of rare accidents (e.g. drowning) was overestimated, and the frequency of common accidents (e.g. bike accidents) underestimated; and the majority of children showed unrealistic optimism tending to see themselves as less likely to suffer these accidents in comparison to their peers, offering superior skills or parental control of the environment as an explanation. In the case of pedestrian accidents, children recognised their seriousness, underestimated the frequency of this risk and regarded their own road crossing skill as protection. These findings highlight the challenging task facing safety educators who, when teaching conventional safety knowledge and routines, also need to alert children to the danger of over-confidence without disabling them though fear.

Perceived risk among parents concerning the travel situation for children with disabilities.
Falkmer, Torbjörn; Gregersen, Nils Petter
2002-07-01
The aim of this study was to describe perceived risk among parents concerning the travel situation for children with disabilities, in addition to their self-reported knowledge of regulations and standards. The results from the present questionnaire study showed that entering and exiting the vehicles often required manual assistance and, thus, was perceived as risky, creating worry among parents. Parents were also worried about professional drivers' lack of knowledge about the child, incautious driving behaviour and lack of adequate safety measures. A poor postural sitting position was a problem in all vehicles. Half of the parents lacked knowledge about the regulations and standards for school transportation and Special Transport Systems. Lack of information seems to be one underlying reason for the parents' worries. Comprehensive information, focused on the special needs of children with disabilities in their transportation, would probably reduce the parents' worries significantly.

High-speed commercial flight transportation is being studied for intercontinental operations in the 21st century, the projected operational characteristics for these aircraft are examined, the radiation environment as it is now known is presented, and the relevant health issues are discussed. Based on a critical examination of the data, a number of specific issues need to be addressed to ensure an adequate knowledge of the ionizing radiation health risks of these aircraft operations. Large uncertainties in our knowledge of the physical fields for high-energy neutrons and multiply-charged ion components need to be reduced. Improved methods for estimating risks in prenatal exposure need to be developed. A firm basis for solar flare monitoring and forecasting needs to be developed with means of exposure abatement.
Volcanic risk: the responsibility of science in communication
NASA Astrophysics Data System (ADS)
Piccione, Caterina
2013-04-01
The knowledge of the places where we live comes both from the experience handed down from one generation to the other and from scientific knowledge. In some cases, natural risks are "invisible", such as earthquakes, in some other cases, natural risks are seemingly "invisible", such as a wall in danger of collapse or a valley in a flood zone. And besides all this, there is volcanic risk, where the power of the forces of nature appears in all its beauty and majesty. The possibility to see volcanoes, to perceive their changes, to observe them closely and the need to live with them, makes it very important for the population living in these areas to have an adequate knowledge of the risk, a knowledge that should be based on scientific research. In Italy the experience of the Istituto Nazionale di Geofisica e Vulcanologia in the Vesuvio area, in the Aeolian Islands and around Etna shows how vital it is to make people aware of volcanic risk. Thanks to the support of the scientific community, the population can develop the best possible coexistence with volcanoes and with the risk they represent. These are extreme situations, but they are the starting point for educational and informative activities continuing to evolve and upgrade in parallel to the availability of new technologies and media and the progress of research that INGV has been conducting for years through specific projects. The scientific community and individual researchers have the ethical duty to share with the community the knowledge on risk, a responsibility that becomes especially important in those areas affected by volcanic risk. It is from this educational action that depends on the awareness of the populations with regard to the risk they are exposed to, that results in a responsible behavior in case of emergency, and that becomes the main variable for the safety of communities coexisting with active volcanoes.

At present, insects are rarely used by the European food industry, but they are a subject of growing interest as an alternative source of raw materials. The risks associated with the use of insects in the production of foods and food ingredients have not been sufficiently investigated. There is a lack of scientifically based knowledge of insect processing to ensure food safety, especially when these processes are carried out on an industrial scale. This review focuses on the safety aspects that need to be considered regarding the fractionation of insects for the production of foods and food ingredients. © 2016 WILEY-VCH Verlag GmbH & Co.

Cervical HPV is the most common sexually transmitted disease among college-age women. This study aimed to assess knowledge and attitudes towards HPV infection, HPV vaccination and cervical cancer among female university students, to provide insight into development of HPV educational information. A cross-sectional survey using a convenience sample. A total of 1083 ethnically diverse female students attending a public university were approached and 650 were interviewed. Knowledge regarding HPV, HPV vaccination, cervical screening and cervical cancer risk factors was remarkably poor. Across the sample, the mean total knowledge score (14-item) was only 3.25 (S.D. +/-2.41; 95% CI 3.07-3.44). Only 10.3% had heard of the newly released HPV vaccine. Approximately 48% of participants indicated an intention to receive an HPV vaccine. Intention to receive an HPV vaccine was significantly associated with knowledge of HPV and genital warts (OR 1.53; 95% CI 1.25-1.88), and knowledge of cervical screening and cervical cancer risk factors (OR 1.21; 95% CI 1.11-1.33). Of those who refused HPV vaccination, 50.9% doubted the safety and efficacy of the new vaccine, and 41.5% perceived themselves as not at risk of HPV infection. The findings suggest that providing education about the etiology of cervical cancer and the HPV link is an essential component to enhance HPV vaccine uptake.

In FY 1991, the NASA Safety Division continued efforts to enhance the quality and productivity of its safety oversight function. Recent initiatives set forth in areas such as training, risk management, safety assurance, operational safety, and safety information systems have matured into viable programs contributing to the safety and success of activities throughout the Agency. Efforts continued to develop a centralized intra-agency safety training program with establishment of the NASA Safety Training Center at the Johnson Space Center (JSC). The objective is to provide quality training for NASA employees and contractors on a broad range of safety-related topics. Courses developed by the Training Center will be presented at various NASA locations to minimize travel and reach the greatest number of people at the least cost. In FY 1991, as part of the ongoing efforts to enhance the total quality of NASA's safety work force, the Safety Training Center initiated development of a Certified Safety Professional review course. This course provides a comprehensive review of the skills and knowledge that well-rounded safety professionals must possess to qualify for professional certification. FY 1992 will see the course presented to NASA and contractor employees at all installations via the NASA Video Teleconference System.
Evaluating the potential human health and/or ecological risks associated with exposures to complex chemical mixtures in the ambient environment is one of the central challenges of chemical safety assessment and environmental protection. There is a need for approaches that can he...

The goals of this review are to summarize the current knowledge on the application of Lactobacillus salivarius as a probiotic in animals and humans, and to address safety concerns with its use on live hosts. Overall, several strains of L. salivarius are well established probiotics with multiple applications in animal health, particularly to reduce colonization by gastrointestinal pathogens, and to a lesser extent, as a production and quality aid. In humans, L. salivarius has been used to prevent and treat a variety of chronic diseases, including asthma, cancer, atopic dermatitis and halitosis, and to a much limited extent, to prevent or treat infections. Based on the results from primary research evidence, it seems that L. salivarius does not pose a health risk to animals or humans in the doses currently used for a variety of applications; however, there is a systematic lack of studies assuring the safety of many of the strains intended for clinical use. This review provides researchers in the field with up-to-date information regarding applications and safety of L. salivarius. Furthermore, it helps researchers identify knowledge gaps and potential opportunities for microbiological and clinical research. © 2017 The Society for Applied Microbiology.

Background Young people are at an increased risk for illness in working life. The authorities stipulate certain goals for training in occupational health and safety (OHS) in vocational schools. A previous study concluded that pupils in vocational education had limited knowledge in the prevention of health risks at work. The aim of the current study, therefore, was to study how OHS training is organized in school and in workplace-based learning (WPL). Methods The study design featured a qualitative approach, which included interviews with 12 headmasters, 20 teachers, and 20 supervisors at companies in which the pupils had their WPL. The study was conducted at 10 upper secondary schools, located in Central Sweden, that were graduating pupils in four vocational programs. Results The interviews with headmasters, teachers, and supervisors indicate a staggered picture of how pupils are prepared for safe work. The headmasters generally give teachers the responsibility for how goals should be reached. Teaching is very much based on risk factors that are present in the workshops and on teachers' own experiences and knowledge. The teaching during WPL also lacks the systematic training in OHS as well as in the traditional classroom environment. Conclusion Teachers and supervisors did not plan the training in OHS in accordance with the provisions of systematic work environment management. Instead, the teachers based the training on their own experiences. Most of the supervisors did not receive information from the schools as to what should be included when introducing OHS issues in WPL. PMID:26929844

In situ simulation training is a team-based training technique conducted on actual patient care units using equipment and resources from that unit, and involving actual members of the healthcare team. We describe our experience with in situ simulation training in a major children's medical centre. In situ simulations were conducted using standardised scenarios approximately twice per month on inpatient hospital units on a rotating basis. Simulations were scheduled so that each unit participated in at least two in situ simulations per year. Simulations were conducted on a revolving schedule alternating on the day and night shifts and were unannounced. Scenarios were preselected to maximise the educational experience, and frequently involved clinical deterioration to cardiopulmonary arrest. We performed 64 of the scheduled 112 (57%) in situ simulations on all shifts and all units over 21 months. We identified 134 latent safety threats and knowledge gaps during these in situ simulations, which we categorised as medication, equipment, and/or resource/system threats. Identification of these errors resulted in modification of systems to reduce the risk of error. In situ simulations also provided a method to reinforce teamwork behaviours, such as the use of assertive statements, role clarity, performance of frequent updating, development of a shared mental model, performance of independent double checks of high-risk medicines, and overcoming authority gradients between team members. Participants stated that the training programme was effective and did not disrupt patient care. In situ simulations can identify latent safety threats, identify knowledge gaps, and reinforce teamwork behaviours when used as part of an organisation-wide safety programme.

One of NASA's goals for long duration space flight is to maintain acceptable levels of crew health, safety, and performance. One way of meeting this goal is through BRAIN, an integrated network of both human and computer elements. BRAIN will function as an advisor to mission managers by assessing the risk of inflight biomedical problems and recommending appropriate countermeasures. Described here is a joint effort among various NASA elements to develop BRAIN and the Infectious Disease Risk Assessment (IDRA) prototype. The implementation of this effort addresses the technological aspects of knowledge acquisition, integration of IDRA components, the use of expert systems to automate the biomedical prediction process, development of a user friendly interface, and integration of IDRA and ExerCISys systems. Because C language, CLIPS and the X-Window System are portable and easily integrated, they were chosen ss the tools for the initial IDRA prototype.
Fuzzy approach for reducing subjectivity in estimating occupational accident severity.
Pinto, Abel; Ribeiro, Rita A; Nunes, Isabel L
2012-03-01
Quantifying or, more generally, estimating the severity of the possible consequences of occupational accidents is a decisive step in any occupational risk assessment process. Because of the lack of historic information (accident data collection and recording are incipient and insufficient, particularly in construction) and the lack of practical tools in the construction industry, the estimation/quantification of occupational accident severity is a notably arbitrary process rather than a systematic and rigorous assessment. This work proposes several severity functions (based on a safety risk assessment) to represent biomechanical knowledge with the aim of determining the severity level of occupational accidents in the construction industry and, consequently, improving occupational risk assessment quality. We follow a fuzzy approach because it makes it possible to capture and represent imprecise knowledge in a simple and understandable way for users and specialists. Copyright © 2011 Elsevier Ltd.

Farmworkers at the border: a bilingual initiative for occupational health and safety.
Acosta, Martha Soledad Vela; Sechrest, Lee; Chen, Mei-Kuang

Bilingual and bicultural occupational health and safety interventions for Hispanic farmworkers are extremely rare and, because of language barriers and cultural differences, issues important to their health and safety on the job remain unaddressed. We designed, conducted, and assessed the first bilingual occupational health and safety education program for farmworkers attending High School Equivalency Programs (HEPs). We took an interdisciplinary participatory approach by integrating educators and researchers with a community advisory board to guide development, evaluation, and implementation of Work Safely-Trabaje con Cuidado Curriculum (Curriculum), a bilingual occupational health and safety curriculum. We created a quasi-experimental design using mixed-method evaluation (quantitative and qualitative elements) via pre- and posttest comparisons, follow-up surveys, and focus groups assessing the Curriculum effect on knowledge, safety risk perception (SRP), and safety behavior. Focus groups and follow-up surveys reflected success and acceptance of the Curriculum among participating farmworkers under the study's logic model. Completion of the Curriculum resulted in statistically significant improvements in the combined score of knowledge and SRP at the posttest (p = 0.001) and follow-up survey (p = 0.02) in the intervention group. After completing this study, the Curriculum was permanently adopted by the two high school equivalency sites involved. The participatory approach resulted in integration of community and applied research partnership. The potential to expand use of this Curriculum by other HEP sites can further assess effectiveness and external validity among underserved minority groups.

Clinical decision support systems (CDSSs) often base their knowledge and advice on human expertise. Knowledge representation needs to be in a format that can be easily understood by human users as well as supporting ongoing knowledge engineering, including evolution and consistency of knowledge. This paper reports on the development of an ontology specification for managing knowledge engineering in a CDSS for assessing and managing risks associated with mental-health problems. The Galatean Risk and Safety Tool, GRiST, represents mental-health expertise in the form of a psychological model of classification. The hierarchical structure was directly represented in the machine using an XML document. Functionality of the model and knowledge management were controlled using attributes in the XML nodes, with an accompanying paper manual for specifying how end-user tools should behave when interfacing with the XML. This paper explains the advantages of using the web-ontology language, OWL, as the specification, details some of the issues and problems encountered in translating the psychological model to OWL, and shows how OWL benefits knowledge engineering. The conclusions are that OWL can have an important role in managing complex knowledge domains for systems based on human expertise without impeding the end-users' understanding of the knowledge base. The generic classification model underpinning GRiST makes it applicable to many decision domains and the accompanying OWL specification facilitates its implementation.

System safety assessment is defined in NPR 8715.3C, NASA General Safety Program Requirements as a disciplined, systematic approach to the analysis of risks resulting from hazards that can affect humans, the environment, and mission assets. Achievement of the highest practicable degree of system safety is one of NASA's highest priorities. Traditionally, system safety assessment at NASA and elsewhere has focused on the application of a set of safety analysis tools to identify safety risks and formulate effective controls.1 Familiar tools used for this purpose include various forms of hazard analyses, failure modes and effects analyses, and probabilistic safety assessment (commonly also referred to as probabilistic risk assessment (PRA)). In the past, it has been assumed that to show that a system is safe, it is sufficient to provide assurance that the process for identifying the hazards has been as comprehensive as possible and that each identified hazard has one or more associated controls. The NASA Aerospace Safety Advisory Panel (ASAP) has made several statements in its annual reports supporting a more holistic approach. In 2006, it recommended that "... a comprehensive risk assessment, communication and acceptance process be implemented to ensure that overall launch risk is considered in an integrated and consistent manner." In 2009, it advocated for "... a process for using a risk-informed design approach to produce a design that is optimally and sufficiently safe." As a rationale for the latter advocacy, it stated that "... the ASAP applauds switching to a performance-based approach because it emphasizes early risk identification to guide designs, thus enabling creative design approaches that might be more efficient, safer, or both." For purposes of this preface, it is worth mentioning three areas where the handbook emphasizes a more holistic type of thinking. First, the handbook takes the position that it is important to not just focus on risk on an individual basis but to consider measures of aggregate safety risk and to ensure wherever possible that there be quantitative measures for evaluating how effective the controls are in reducing these aggregate risks. The term aggregate risk, when used in this handbook, refers to the accumulation of risks from individual scenarios that lead to a shortfall in safety performance at a high level: e.g., an excessively high probability of loss of crew, loss of mission, planetary contamination, etc. Without aggregated quantitative measures such as these, it is not reasonable to expect that safety has been optimized with respect to other technical and programmatic objectives. At the same time, it is fully recognized that not all sources of risk are amenable to precise quantitative analysis and that the use of qualitative approaches and bounding estimates may be appropriate for those risk sources. Second, the handbook stresses the necessity of developing confidence that the controls derived for the purpose of achieving system safety not only handle risks that have been identified and properly characterized but also provide a general, more holistic means for protecting against unidentified or uncharacterized risks. For example, while it is not possible to be assured that all credible causes of risk have been identified, there are defenses that can provide protection against broad categories of risks and thereby increase the chances that individual causes are contained. Third, the handbook strives at all times to treat uncertainties as an integral aspect of risk and as a part of making decisions. The term "uncertainty" here does not refer to an actuarial type of data analysis, but rather to a characterization of our state of knowledge regarding results from logical and physical models that approximate reality. Uncertainty analysis finds how the output parameters of the models are related to plausible variations in the input parameters and in the modeling assumptions. The evaluation of unrtainties represents a method of probabilistic thinking wherein the analyst and decision makers recognize possible outcomes other than the outcome perceived to be "most likely." Without this type of analysis, it is not possible to determine the worth of an analysis product as a basis for making decisions related to safety and mission success. In line with these considerations the handbook does not take a hazard-analysis-centric approach to system safety. Hazard analysis remains a useful tool to facilitate brainstorming but does not substitute for a more holistic approach geared to a comprehensive identification and understanding of individual risk issues and their contributions to aggregate safety risks. The handbook strives to emphasize the importance of identifying the most critical scenarios that contribute to the risk of not meeting the agreed-upon safety objectives and requirements using all appropriate tools (including but not limited to hazard analysis). Thereafter, emphasis shifts to identifying the risk drivers that cause these scenarios to be critical and ensuring that there are controls directed toward preventing or mitigating the risk drivers. To address these and other areas, the handbook advocates a proactive, analytic-deliberative, risk-informed approach to system safety, enabling the integration of system safety activities with systems engineering and risk management processes. It emphasizes how one can systematically provide the necessary evidence to substantiate the claim that a system is safe to within an acceptable risk tolerance, and that safety has been achieved in a cost-effective manner. The methodology discussed in this handbook is part of a systems engineering process and is intended to be integral to the system safety practices being conducted by the NASA safety and mission assurance and systems engineering organizations. The handbook posits that to conclude that a system is adequately safe, it is necessary to consider a set of safety claims that derive from the safety objectives of the organization. The safety claims are developed from a hierarchy of safety objectives and are therefore hierarchical themselves. Assurance that all the claims are true within acceptable risk tolerance limits implies that all of the safety objectives have been satisfied, and therefore that the system is safe. The acceptable risk tolerance limits are provided by the authority who must make the decision whether or not to proceed to the next step in the life cycle. These tolerances are therefore referred to as the decision maker's risk tolerances. In general, the safety claims address two fundamental facets of safety: 1) whether required safety thresholds or goals have been achieved, and 2) whether the safety risk is as low as possible within reasonable impacts on cost, schedule, and performance. The latter facet includes consideration of controls that are collective in nature (i.e., apply generically to broad categories of risks) and thereby provide protection against unidentified or uncharacterized risks.
Integrating legal liabilities in nanomanufacturing risk management.

Among other things, the wide-scale development and use of nanomaterials is expected to produce costly regulatory and civil liabilities for nanomanufacturers due to lingering uncertainties, unanticipated effects, and potential toxicity. The life-cycle environmental, health, and safety (EHS) risks of nanomaterials are currently being studied, but the corresponding legal risks have not been systematically addressed. With the aid of a systematic approach that holistically evaluates and accounts for uncertainties about the inherent properties of nanomaterials, it is possible to provide an order of magnitude estimate of liability risks from regulatory and litigious sources based on current knowledge. In this work, we present a conceptual framework for integrating estimated legal liabilities with EHS risks across nanomaterial life-cycle stages using empirical knowledge in the field, scientific and legal judgment, probabilistic risk assessment, and multicriteria decision analysis. Such estimates will provide investors and operators with a basis to compare different technologies and practices and will also inform regulatory and legislative bodies in determining standards that balance risks with technical advancement. We illustrate the framework through the hypothetical case of a manufacturer of nanoscale titanium dioxide and use the resulting expected legal costs to evaluate alternative risk-management actions.

The INSuLa project consisted of a national survey on health and safety at work involving all the relevant actors such as workers, employers, occupational physicians (MC), worker safety representatives (RLS), prevention and safety service in the workplace (SPSAL). The survey aimed, on one hand, at investigating workers' risk perceptions at the workplace and, on another hand, at exploring the general level of awareness about the enforcement of the Legislative Decree 81/2008 and subsequent amendments. The survey was conducted on a stratified sample of8000 workers representative of the national situation taking into consideration some of the most important socio-demographic and occupational variables, such as gender, geographic area, age, type of contract and sector of activity. The analysis of the results presented here and the subsequent secondary analyses will contribute to identify the needs and critical issues for implementing preventive interventions at the workplaces, also in consideration of the emerging risks and changes in the world of work.

With the rapid aging of the criminal justice population, legal professionals increasingly provide front-line identification and response to age-related health conditions (including cognitive and physical impairments) that may affect legal outcomes, such as the ability to participate in one's defense or stay safe in jail. The goals of this study were to assess legal professionals’ ability to recognize and respond to age-related conditions that could affect legal outcomes and to identify recommendations to address important knowledge gaps. This was a mixed quantitative-qualitative study. Legal professionals (N=72) in the criminal justice system were surveyed to describe their demographics, expertise and prior aging-related training, and to inform the qualitative interview guide. Those surveyed included attorneys (district attorneys (25%), public defenders and legal advocates (58%)), judges (6%), and court-affiliated social workers (11%). In-depth qualitative interviews were then conducted with a subset of 10 legal professionals who worked with older adults at least weekly. Results from the surveys and interviews revealed knowledge deficits in four important areas: age-related health, identification of cognitive impairment, assessment of safety risk, and optimization of services upon release from jail. Four recommendations to close these gaps emerged: (1) educate legal professionals about age-related health; (2) train professionals to identify cognitive and sensory impairment; (3) develop checklists to identify those at risk of poor health or safety; and (4) improve knowledge of and access to transitional services for older adults. These findings suggest that geriatrics knowledge gaps among legal professionals exist that may lead to adverse medical or legal outcomes for criminal justice-involved older adults and that partnerships between healthcare and legal professionals are needed to address these challenges.

The National Association of Schools of Music (NASM) recently ratified a new health and safety standard requiring schools of music to inform students about health concerns related to music. While organizations such as the Performing Arts Medicine Association have developed advisories, the exact implementation is the prerogative of the institution. One possible approach is to embed health education activities into existing methods courses that are routinely offered to music education majors. This may influence student awareness, knowledge, and the perception of competency and responsibility for addressing health risks associated with learning and performing musical instruments. Unfortunately, there are no known lesson plans or curriculum guides for supporting such activities. Therefore, the purpose of this study is to (1) develop course objectives and content that can be applied to a preexisting brass methods course, (2) implement course objectives into a semester-long brass methods course, and (3) test the effectiveness of this intervention on students' awareness, knowledge, perception of competency, and responsibly of health risks that are related to learning and performing brass instruments. Results showcase the potential for modifying methods courses without compromising the other objectives of the course. Additionally, students' awareness, knowledge, perception of competency, and responsibility were positively influenced as measured by changes in pre to post responses to survey group questions.

The subject of this study is the analysis of DPR 177/2011 regarding occupational safety in confined environments suspected of pollution The study wishes to represent a platform for the knowledge of the relevant principles and issues that are the functional basis for occupational health professionals, to offer a scheme in which it is possible to implement local actions of occupational prevention in the confined spaces and to help Italian intervention plans Italian within the European area, such, e.g., the present "Healthy workplaces campaign working together for risk prevention" promoted by the European Agency for Safety and Health at Work. The interiorization of this behavioural scheme is needed for professionals and authorities in the occupational safety systems, both public and private, who have the institutional duty to obtain trheir effectiveness. To observe the safety system in the specific matter of confined spaces, their essential elements were considered. These elements were identified both in the DPR 177/2011 and in other pertinent documents. This study doesn't pretend to identify all relevant documents, but wishes to underline the open structure of the system for acquiring non strictly juridical documents, such as ICOH guidelines and International code of ethics for occupational health professionals and pertinent authorities. A specific matter of the study is the different role of rules and ethical principles in verifying the adequacy of the safety system. The role of guidelines and ethic principles in the internal evaluation of legal value was examined for their relevance in order to decide on adequacy of the employer's management in safety matter adequacy which can by evaluated looking at his effective knowledge of spaces and good selection of managers and professionals. Furthermore, the study establishes how central--in reaching the safety--is the method based on effectiveness in managing the prevention in occupational health. The managerial method, not based on formal interpretation but on the effective situation of the spaces and of the human resources, is a critical element in safety systems and represents an acceptable scheme for the conduct of the subjects in charge for the production cycle. They are those who effectively decide on the site, except for some situations, as it is for example the prevision of managerial liability for activity in outsourcing. It has been stressed in this study the dynamicity of safety system in confined spaces which can be derived by the employer's duty of vigilance for interference risks between his activity and the activity of other enterprises operating in outsourcing. This duty it is permanent in every space and moment of production cycle. This context of functional responsibility, and liability when it exists, based on reality as well as on the knowledge of the spaces and human resources, shows the central function of qualified MD and his functionality in both aspects. In the first, he is able to understand various risks existing for health. In the second, for the many strict contacts with workers, he can participate in developing their information and formation, which have educational importance for the safety system of the occupational health. To conclude about the occupational safety system, this study stresses that the activity of qualified MD is not a simple surveillance carried out by medical examinations as a routine, but it is a strategic issue for the realization of organizational wellness at work, which is functional to respect both the human rights and an efficient production cycle.

The aim of the study was to explore, in the Malaysian general population: knowledge and beliefs of the characteristics in general of medication-related side effects and side effects associated with different types of medicines; behaviour related to the safe use of drugs before and after taking a medication; and behaviour in the event of a medication-related side effect. A 24-item self-administered questionnaire was developed and used to survey the general public living or working in suburban Kuala Lumpur, Malaysia. Eight hundred questionnaires were distributed, face to face, by researchers using quota sampling. Respondents' knowledge, belief and behaviour were analysed and correlated with demographics, medical history and experience of side effects. Six hundred and ten respondents completed the questionnaire giving a response rate of 76.3%. The mean knowledge score for the respondents was 18.4±3.6 out of the maximum possible score of 26. Educational level and experience of side effect had an influence on the knowledge score obtained. Respondents had misconceptions regarding the safety of complementary and alternative medicines (CAMs) and over-the-counter medications. Medication history and previous experience with side effects had a significant influence on the higher behaviour score obtained. The survey has shown moderate results with regard to the knowledge of public regarding safety of medications, and there was evidence of under-estimating the risk of medications, especially CAMs. The misconceptions among the public, and inappropriate behaviour on drug safety-related aspects, is a concern which needs to be addressed in the interventions designed. © 2011 The Authors.

At time of approval, knowledge of the full benefit risk of any drug is limited, in particular with regards to safety. Post-approval surveillance of potential drug safety concerns is recognized as an important task of regulatory agencies. For innovative, often first-in-class drugs, safety knowledge at time of approval is often even less extensive and these may require tighter scrutiny post approval. We evaluated whether more post-approval serious safety issues were identified for drugs with a higher level of innovation. A cohort study was performed that included all new active substances approved under the European Centralized Procedure and for which serious safety issues were identified post-approval from 1 January 1999 to 1 January 2012. Serious safety issues were defined as issues requiring a Direct Healthcare Professional Communication to alert individual healthcare professionals of a new serious safety issue, or a safety-related drug withdrawal. Data were retrieved from publicly available websites of the Dutch Medicines Evaluation Board and the European Medicines Agency. The level of innovation was scored using a validated algorithm, grading drugs as important (A), moderate (B) or modest (C) innovations or as pharmacological or technological (pharm/tech) innovations. The data were analyzed using appropriate descriptive statistics and Kaplan-Meier analysis, with a Mantel-Cox log-rank test, and Cox-regression models correcting for follow-up duration, to identify a possible trend in serious safety issues with an increasing level of innovation. In Europe, 279 new drugs were approved between 1999 and 2011. Fifty-nine (21 %) were graded as important, 63 (23 %) moderate, or 34 (12 %) modest innovations and 123 (44 %) as non-innovative (pharm/tech), while 15 (25 %), 13 (21 %), 8 (24 %) and 17 (14 %) had post-approval safety issues, respectively (p = 0.06, linear-by-linear test). Five drugs were withdrawn from the market. The Kaplan-Meier-derived probability for having a first serious safety issue was statistically significant, log-rank (Mantel-Cox) p = 0.036. In the final adjusted Cox proportional hazard model there was no statistically significant difference in occurrence of a first serious safety issue for important, moderate and modest innovations versus non-innovative drugs; hazard ratios 1.76 (95 % CI 0.82-3.77), 1.61 (95 % CI 0.76-3.41)], and 1.25 (95 % CI 0.51-3.06), respectively. A higher level of innovation was not clearly related to an increased risk of serious safety issues identified after approval.

Unsafe injection practices and injection overuse are widespread in developing countries harming the patient and inviting risks to the health care workers. In Nepal, there is a dearth of documented information about injection practices so the present study was carried out: a) to determine whether the selected government health facilities satisfy the conditions for safe injections in terms of staff training, availability of sterile injectable equipment and their proper disposal after use and b) to assess knowledge and attitudes of healthcare workers in these health care facilities with regard to injection safety. A descriptive cross-sectional mixed type (qualitative and quantitative) survey was carried out from 18th May to 16th June 2012. In-depth interviews with the in-charges were conducted using a semi-structured questionnaire. Observation of the health facilities using a structured observation tool was done. The data were analysed manually by summarizing, tabulating and presenting in various formats. The in-charges (eight males, two females) who participated in the study ranged in age from 30 to 50 years with a mean age of 37.8 years. Severe infection followed by pain was the most important cause for injection use with injection Gentamicin being most commonly prescribed. New single use (disposable) injections and auto-disable syringes were used to inject curative drugs and vaccines respectively. Sufficient safety boxes were also supplied to dispose the used syringe. All health care workers had received full course of Hepatitis B vaccine and were knowledgeable about at least one pathogen transmitted through unsafe injection practices. Injection safety management policy and waste disposal guideline was not available for viewing in any of the facilities. The office staff who disposed the bio-medical wastes did so without taking any safety measures. Moreover, none of these staff had received any formal training in waste management. Certain safe injection practices were noticed in the studied health care facilities but there remain a number of grey areas where unsafe practices still persists placing patient and health workers at risk of associated hazards. Training concentrating on injection safety, guidelines to dispose biomedical waste and monitoring of the activity is needed.

Background Unsafe injection practices and injection overuse are widespread in developing countries harming the patient and inviting risks to the health care workers. In Nepal, there is a dearth of documented information about injection practices so the present study was carried out: a) to determine whether the selected government health facilities satisfy the conditions for safe injections in terms of staff training, availability of sterile injectable equipment and their proper disposal after use and b) to assess knowledge and attitudes of healthcare workers in these health care facilities with regard to injection safety. Methodology A descriptive cross-sectional mixed type (qualitative and quantitative) survey was carried out from 18th May to 16th June 2012. In-depth interviews with the in-charges were conducted using a semi-structured questionnaire. Observation of the health facilities using a structured observation tool was done. The data were analysed manually by summarizing, tabulating and presenting in various formats. Results The in-charges (eight males, two females) who participated in the study ranged in age from 30 to 50 years with a mean age of 37.8 years. Severe infection followed by pain was the most important cause for injection use with injection Gentamicin being most commonly prescribed. New single use (disposable) injections and auto-disable syringes were used to inject curative drugs and vaccines respectively. Sufficient safety boxes were also supplied to dispose the used syringe. All health care workers had received full course of Hepatitis B vaccine and were knowledgeable about at least one pathogen transmitted through unsafe injection practices. Injection safety management policy and waste disposal guideline was not available for viewing in any of the facilities. The office staff who disposed the bio-medical wastes did so without taking any safety measures. Moreover, none of these staff had received any formal training in waste management. Conclusions Certain safe injection practices were noticed in the studied health care facilities but there remain a number of grey areas where unsafe practices still persists placing patient and health workers at risk of associated hazards. Training concentrating on injection safety, guidelines to dispose biomedical waste and monitoring of the activity is needed. PMID:23286907

To identify the degree of knowledge and performance of bio-safety measures by nursing students and knowing the type of biological accidents suffered during their clinical practice. A cross-sectional study was conducted on the students of three Nursing courses held in May of 2008. Data was collected by an anonymous self-administered questionnaire, with a return of 54%. A total of 97% of students seemed to know the standard biosafety measures, and all of them (100%) stated that those measures must be applied to every patient. However, the reality of clinical practice shows that biosafety measures are only partially applied. An average of 60.2% implement the personal hygiene measures, 66.1% use physical barriers, and 44% use sharp materials safely. Around 32.25% of the students have suffered some biological accident, with a greater incidence in the second year: administering injections (24%), drawing blood samples with Venojet needles (18%) and recapping used needles (17%). The high level of knowledge shown by the students on standard precautions is not always shown in clinical practice. There are significant deficiencies in student safety practices: recapping of used needles continues to be one of the most common risk practices carried out. Copyright (c) 2009 Elsevier España, S.L.

Foodborne disease causes an estimated 48 million illnesses and 3,000 deaths annually (Scallan E, et al., Emerg Infect Dis 17:7-15, 2011), with U.S. economic costs estimated at $152 billion to $1.4 trillion annually (Roberts T, Am J Agric Econ 89:1183-1188, 2007; Scharff RL, http://www.pewtrusts.org/en/research-and-analysis/reports/0001/01/01/healthrelated-costs-from-foodborne-illness-in-the-united-states, 2010). An increasing number of these illnesses are associated with fresh fruits and vegetables. An analysis of outbreaks from 1990 to 2003 found that 12% of outbreaks and 20% of outbreak-related illnesses were associated with produce (Klein S, Smith DeWaal CS, Center for Science in the Public Interest, https://cspinet.org/sites/default/files/attachment/ddreport.pdf, June 2008; Lynch M, Tauxe R, Hedberg C, Epidemiol Infect 137:307-315, 2009). These food safety problems have resulted in various stakeholders recommending the shift to a more preventative and risk-based food safety system. A modern risk-based food safety system takes a farm-to-fork preventative approach to food safety and relies on the proactive collection and analysis of data to better understand potential hazards and risk factors, to design and evaluate interventions, and to prioritize prevention efforts. Such a system focuses limited resources at the points in the food system with the likelihood of having greatest benefit to public health. As shared kitchens, food hubs, and local food systems such as community supported agriculture are becoming more prevalent throughout the United States, so are foodborne illness outbreaks at these locations. At these locations, many with limited resources, food safety methods of prevention are rarely the main focus. This lack of focus on food safety knowledge is why a growing number of foodborne illness outbreaks are occurring at these locations.

To assess knowledge, attitudes and practices of U.S. dental hygienists with infection control guidelines (ICG). Research has shown improved compliance with specific aspects of dental ICG is needed. This study supports the American Dental Hygienists' Association National Research Agenda's Occupational Health and Safety objective to investigate methods to decrease errors, risks and or hazards in health care. Data are needed to assess compliance, prevention and behavioral issues with current ICG practices. A proportional stratified random sample (n=2,500) was recruited for an online survey. Descriptive statistics summarized demographic characteristics and knowledge, attitudes and practices responses. Spearman's rho correlations determined relationships between knowledge, attitudes and practices responses (p<0.05). Dominant themes were identified from open-ended responses. A 31% response rate (n=765) was attained. Respondents agreed/strongly agreed with familiarity with ICG (86%) and believed ICG are relevant to their patients (88%). Responses indicated low compliance (rarely/never used) with handpiece sterilization (n=209, 31%), utility glove use (n=317, 47%), and pre-procedural rinsing (n=324, 48%). Significant relationships were found between ICG implementation and access to necessary supplies (rs=0.549), supervisors' expectations for using ICG (rs=0.529) and no time to use (rs=-0.537). Themes from comments indicated time is a barrier, and respondents' perceived a need for involvement of all co-workers. Dental hygienists are adhering with most aspects of the ICG. High compliance with ICG among respondents in this study was associated with positive safety beliefs and practices, whereas lower compliance with ICG was associated with less positive safety beliefs and practices. A safety culture appears to be a factor in compliance with ICG.

Masons have the highest rate of overexertion injuries among all construction trades and rank second for occupational back injuries in the United States. Identified ergonomic solutions are the primary method of reducing exposure to risk factors associated with musculoskeletal disorders. However, many construction workers lack knowledge about these solutions, as well as basic ergonomic principles. Construction apprentices, as they embark on their careers, are greatly in need of ergonomics training to minimize the cumulative exposure that leads to musculoskeletal disorders. Apprentices receive safety training; however, ergonomics training is often limited or non-existent. In addition, apprenticeship programs often lack "soft skills" training on how to appropriately respond to work environments and practices that are unsafe. The SAVE program - SAfety Voice for Ergonomics - strives to integrate evidence-based health and safety training strategies into masonry apprenticeship skills training to teach ergonomics, problem solving, and speaking up to communicate solutions that reduce musculoskeletal injury risk. The central hypothesis is that the combination of ergonomics training and safety voice promotion will be more effective than no training or either ergonomics training alone or safety voice training alone. Following the development and pilot testing of the SAVE intervention, SAVE will be evaluated in a cluster-randomized controlled trial at 12 masonry training centers across the U.S. Clusters of apprentices within centers will be assigned at random to one of four intervention groups (n = 24 per group): (1) ergonomics training only, (2) safety voice training only, (3) combined ergonomics and safety voice training, or (4) control group with no additional training intervention. Outcomes assessed at baseline, at the conclusion of training, and then at six and 12 months post training will include: musculoskeletal symptoms, general health perceptions, knowledge of ergonomic and safety voice principles, and perception and attitudes about ergonomic and safety voice issues. Masons continue to have a high rate of musculoskeletal disorders. The trade has an expected increase of 40 % in the number of workers by 2020. Therefore, a vetted intervention for apprentices entering the trade, such as SAVE, could reduce the burden of musculoskeletal disorders currently plaguing the trade.

Human evaluation and judgement may include errors that can have disastrous results. Within medicine and healthcare there has been slow progress towards major changes in safety. Healthcare lags behind other specialised industries, such as aviation and nuclear power, where there have been significant improvements in overall safety, especially in reducing risk of errors. Following several high profile cases in the USA during the 1990s, a report titled "To Err Is Human: Building a Safer Health System" was published. The report extrapolated that in the USA approximately 50,000 to 100,000 patients may die each year as a result of medical errors. Traditionally otolaryngology has always been regarded as a "safe specialty". A study in the USA in 2004 inferred that there may be 2600 cases of major morbidity and 165 deaths within the specialty. MEDLINE via PubMed interface was searched for English language articles published between 2000 and 2012. Each combined two or three of the keywords noted earlier. Limitations are related to several generic topics within patient safety in otolaryngology. Other areas covered have been current relevant topics due to recent interest or new advances in technology. There has been a heightened awareness within the healthcare community of patient safety; it has become a major priority. Focus has shifted from apportioning blame to prevention of the errors and implementation of patient safety mechanisms in healthcare delivery. Type of Errors can be divided into errors due to action and errors due to knowledge or planning. In healthcare there are several factors that may influence adverse events and patient safety. Although technology may improve patient safety, it also introduces new sources of error. The ability to work with people allows for the increase in safety netting. Team working has been shown to have a beneficial effect on patient safety. Any field of work involving human decision-making will always have a risk of error. Within Otolaryngology, although patient safety has evolved along similar themes as other surgical specialties; there are several specific high-risk areas. Medical error is a common problem and its human cost is of immense importance. Steps to reduce such errors require the identification of high-risk practice within a complex healthcare system. The commitment to patient safety and quality improvement in medicine depend on personal responsibility and professional accountability.

Historically, there is a tendency to focus on seismic structural performance of buildings, neglecting the potential for damage of non-structural elements. In particular, non-structural elements of buildings are their architectural parts (i.e. partitions, ceilings, cladding), electrical and mechanical components (i.e., distribution panels, piping, plumbing), and contents (e.g., furniture, bookcases, computers and desktop equipment). Damage of these elements often contributes significantly to earthquake impacts. In the 1999 Izmit Earthquake, Turkey, 50% of the injuries and 3% of human losses were caused by non-structural failures. In the 2010-2011 Christchurch Earthquakes (New Zealand), 40% of building damage was induced by non-structural malfunctions. Around 70%-85% of construction cost goes into these elements, and their damage can strongly influence the ability of communities to cope with and recover from earthquakes. The project Know your city, Reduce seISmic risK through non-structural elements (KnowRISK) aims at facilitating local communities' access to expert knowledge on non-structural seismic protection solutions. The project will study seismic scenarios critical for non-structural damage, produce a portfolio of non-structural protection measures and investigate the level of awareness in specific communities. We will implement risk communication strategies that will take into account the social and cultural background and a participatory approach to raise awareness in local communities. The paradox between the progress of scientific knowledge and the ongoing increase of losses from natural disasters worldwide is a well-identified gap in the UN Hyogo Framework for Action 2005-2015, in which one of the main priorities is the investment on "knowledge use, innovation and education to build a culture of safety and resilience". The KnowRISK is well aligned with these priorities and will contribute to participatory action aimed at: i) transferring expert knowledge on seismic risk and non-structural protective solutions into practical knowledge and ii) communication tools designed to engage communities in disaster risk reduction
Knowledge Capture and Management for Space Flight Systems

Goodman, John L.
2005-01-01
The incorporation of knowledge capture and knowledge management strategies early in the development phase of an exploration program is necessary for safe and successful missions of human and robotic exploration vehicles over the life of a program. Following the transition from the development to the flight phase, loss of underlying theory and rationale governing design and requirements occur through a number of mechanisms. This degrades the quality of engineering work resulting in increased life cycle costs and risk to mission success and safety of flight. Due to budget constraints, concerned personnel in legacy programs often have to improvise methods for knowledge capture and management using existing, but often sub-optimal, information technology and archival resources. Application of advanced information technology to perform knowledge capture and management would be most effective if program wide requirements are defined at the beginning of a program.

Nanomaterials are widely present in many industrial sectors (e.g., chemical, biomedical, environment), and their application is expected to significantly expand in the coming years. However, nanomaterial use raises many questions about the potential risks to human health and the environment and, more specifically, to occupational health. The available literature supports the ability of the lung, gastrointestinal tract, and skin to act as significant barriers against systemic exposure to many nanomaterials. However, because a potential risk issue exists about the toxicity of nanomaterials to the biological material, tools need to be developed for improving the risk management of the regulators. The goal is to develop a tool that examines the current knowledge base regarding the health risks posed by engineered nanoparticles to improve nanotechnology safety prior to the marketing phase. The approach proposed during this work was to establish a safety assessment constructed on a decision-control pathway regarding nanomaterial production and consumer's product to integrate different aspects. These aspects include: (1) primarily research and identification of the nanomaterial base of physicochemical properties, toxicity, and application; (2) the occupational exposure risk during the manufacturing process; (3) and the engineered nanomaterial upon the consumer product. This approach provides important parameters to reduce the uncertainty related to the production of nanomaterials prior their commercialization, reduce the reluctance from the industry, and provide a certification tool of sanitary control for the regulators. This work provides a better understanding of a critical issue of nanomaterials and consumer safety.
Informed consent in blood transfusion: knowledge and administrative issues in Uganda hospitals.

Blood as a transplant is not free of risks. Clinicians and patients ought to know the parameters of a transfusion informed consent. A mixed methodology to explore patients' and clinicians' knowledge and opinions of administration and strategies to improve the transfusion informed consent process was conducted. The clinicians' level of knowledge was limited to provision of information about and the right to consent to a transfusion. They disagreed on administrative issues but had acceptable opinions on improving the process. Patients perceived this process as a way of assurance of blood safety. This process is important and should not be omitted. Copyright © 2010 Elsevier Ltd. All rights reserved.
Food safety issues and training methods for ready-to-eat foods in the grocery industry.
Binkley, Margaret; Ghiselli, Richard
2005-10-01
As Americans have become more pressed for time, the use of convenient, simplified meals become a way of life. One aspect of this trend, known as Home Meal Replacement (IIMR), has increased in sales since its inception. Between 1999 and 2001, the average annual expenditure per consumer rose 5.6 pereent, and $958 per person per year was spent in 2002. Along with this growth, food safety risks may have increased. The study reported here examined efforts being undertaken by grocery and convenience stores to control the wholesomeness of INR food items. After a convenience sample of 500 grocery store executives was identified, a 32-item questionnaire was developed and mailed to the executives. The results indicate that the industry has taken food safety seriously with only 10 pereent reporting that they have no food safety training. The executives cited employee turnover as a major concern in food safety today, along with lack of food safety knowledge of the consumer and improper holding temperatures.

To implement a communication network for safety problem identification and solution sharing among rural community pharmacists and to report participating pharmacists' perceived value and impact of the network on patient safety after 1 year of implementation. Action research study. Rural community pharmacies in Nebraska from January 2010 to April 2011. Rural community pharmacists who voluntarily agreed to join the Pharmacists for Patient Safety Network in Nebraska. Pharmacists reported errors, near misses, and safety concerns through Web-based event reporting. A rapid feedback process was used to provide patient safety solutions to consider implementing across the network. Qualitative interviews were conducted 1 year after program implementation with participating pharmacists to assess use of the reporting system, value of the disseminated safety solutions, and perceived impact on patient safety in pharmacies. 30 of 38 pharmacists participating in the project completed the interviews. The communication network improved pharmacist awareness, promoted open discussion and knowledge sharing, contributed to practice vigilance, and led to incorporation of proactive safety prevention practices. Despite low participation in error and near-miss reporting, a dynamic communication network designed to rapidly disseminate evidence-based patient safety strategies to reduce risk was valued and effective at improving patient safety practices in rural community pharmacies.

To evaluate and implement the WalkSafe Pre-Kindergarten Pedestrian Safety Curriculum. A quasi-experimental pretest-posttest design without a control group was used to measure children's pedestrian safety knowledge. Knowledge assessments consisting of multiple-choice and short-answer questions were administered pre- and post-curriculum implementation by classroom teachers. Knowledge assessments gauged prekindergarten students' knowledge of pedestrian safety activities prior to safety curriculum implementation and, again, after the students received the curriculum. A total of 605 children (aged 3- to 5-year) from 38 prekindergarten classrooms in 16 randomly selected elementary schools participated in the pedestrian safety education pilot program. Subjects were of multiethnic and diverse backgrounds from the Miami-Dade County Public School District. Of the 605 educated subjects, 454 children completed both pre- and posttests. A statistically significant difference was found between pretest knowledge (M = 5.49, SD = 1.54) and posttest knowledge (M = 6.64, SD = 1.35) assessment scores across all 454 subjects, t(452) = -16.22, p < .001, 95% CI [-1.29, -1.01]. Previous studies have shown that classroom-based training of children as young as 4 years old can yield significant improvements in traffic safety knowledge. The statistical findings of the WalkSafe Pre-Kindergarten Pedestrian Safety Curriculum revealed statistically significant improvements in pedestrian safety knowledge of these young children. Future research efforts will focus on longitudinal behavioral changes in these students and an increase in pedestrian safety behaviors (e.g., utilization of crosswalks or sidewalks).

The xenotransplantation of porcine tissues may help overcome the shortage of human organs for transplantation. However, there are some concerns about recipient safety because the risk of porcine endogenous retrovirus (PERV) transmission to human cells remains unknown. Although, to date, no PERV infections have been noted in vivo, the possibility of such infections has been confirmed in vitro. Better understanding of the structure and replication cycle of PERVs is a prerequisite for determining the risk of infection and planning PERV-detection strategies. This review presents the current state of knowledge about the structure and replication cycle of PERVs in the context of retroviral infection risk. PMID:29755422
Assessment of Risk Communication about Undercooked Hamburgers by Restaurant Servers.

2016-12-01
According to the U.S. Food and Drug Administration 2013 Model Food Code, it is the duty of a food establishment to disclose and remind consumers of risk when ordering undercooked food such as ground beef. The purpose of this study was to explore actual risk communication behaviors of food establishment servers. Secret shoppers visited 265 restaurants in seven geographic locations across the United States, ordered medium rare burgers, and collected and coded risk information from chain and independent restaurant menus and from server responses. The majority of servers reported an unreliable method of doneness (77%) or other incorrect information (66%) related to burger doneness and safety. These results indicate major gaps in server knowledge and risk communication, and the current risk communication language in the Model Food Code does not sufficiently fill these gaps. The question is "should servers even be acting as risk communicators?" There are numerous challenges associated with this practice, including high turnover rates, limited education, and the high stress environment based on pleasing a customer. If servers are designated as risk communicators, food establishment staff should be adequately trained and provided with consumer advisory messages that are accurate, audience appropriate, and delivered in a professional manner so that customers can make informed food safety decisions.

Emerging issues in occupational safety and health.
Schulte, Paul A
2006-01-01
In developed countries, changes in the nature of work and the workforce may necessitate recalibrating the vision of occupational safety and health (OSH) researchers, practitioners, and policymakers to increase the focus on the most important issues. New methods of organizing the workplace, extensive labor contracting, expansion of service and knowledge sectors, increase in small business, aging and immigrant workers, and the continued existence of traditional hazards in high-risk sectors such as construction, mining, agriculture, health care, and transportation support the need to address: 1) broader consideration of the role and impact of work, 2) relationship between work and psychological dysfunction, 3) increased surveillance basis for research and intervention, 4) overcoming barriers to the conduct and use of epidemiologic research, 5) information and knowledge transfer and application, 6) economic issues in prevention, and 7) the global interconnectedness of OSH. These issues are offered to spur thinking as new national research agendas for OSH are considered for developed countries.

The use of peripheral vascular catheters (PVCs) is an extremely common and necessary clinical intervention, but inappropriate PVC care poses a major patient safety risk in terms of infection. Quality improvement initiatives have been proposed to reduce the likelihood of adverse events, but a lack of understanding about factors that influence behaviours of healthcare professionals limits the efficacy of such interventions. We undertook qualitative interviews with clinical staff from a large group of hospitals in order to understand influences on PVC care behaviors and subsequent patient safety. Ten doctors, ten clinical pharmacists, 18 nurses and one midwife at a National Health Service hospital group in London (United Kingdom) were interviewed between December 2010 and July 2011 using qualitative methods. Responses were analysed using a thematic framework. FOUR KEY THEMES EMERGED: 1) Fragmentation of management and care, demonstrated with a lack of general overview and insufficient knowledge about expected standards of care or responsibility of different professionals; 2) feelings of resentment and frustration as a result of tensions in the workplace, due to the ambiguity about professional responsibilities; 3) disregard for existing hospital policy due to perceptions of flaws in the evidence used to support it; and 4) low-risk perception for the impact of PVC use on patient safety. Fragmentation of practice resulted in ill-defined responsibilities and interdisciplinary resentment, which coupled with a generally low perception of risk of catheter use, appeared to result in lack of maintaining policy PVC standards which could reduced patient safety. Resolution of these issues through clearly defining handover practice, teaching interdisciplinary duties and increasing awareness of PVC risks could result in preventing thousands of BSIs and other PVC-related infections annually.

In this article, we develop and meta-analytically test the relationship between job demands and resources and burnout, engagement, and safety outcomes in the workplace. In a meta-analysis of 203 independent samples (N = 186,440), we found support for a health impairment process and for a motivational process as mechanisms through which job demands and resources relate to safety outcomes. In particular, we found that job demands such as risks and hazards and complexity impair employees' health and positively relate to burnout. Likewise, we found support for job resources such as knowledge, autonomy, and a supportive environment motivating employees and positively relating to engagement. Job demands were found to hinder an employee with a negative relationship to engagement, whereas job resources were found to negatively relate to burnout. Finally, we found that burnout was negatively related to working safely but that engagement motivated employees and was positively related to working safely. Across industries, risks and hazards was the most consistent job demand and a supportive environment was the most consistent job resource in terms of explaining variance in burnout, engagement, and safety outcomes. The type of job demand that explained the most variance differed by industry, whereas a supportive environment remained consistent in explaining the most variance in all industries.
Buyer beware: personnel selling nail guns know little about dangerous tools.

Nail gun use is ubiquitous in wood frame construction. Accessibility and decreasing costs have extended associated occupational hazards to consumers. Compelling evidence documents decreased injury risk among trained users and those with tools with sequential triggers. To prevent inadvertent discharge of nails, this safer trigger requires the nose be depressed before the trigger is pulled to fire. The sequential trigger is not required by the Consumer Product Safety Commission (CPSC) or the Occupational Safety and Health Administration (OSHA) nor are there any guidelines for training. We collected data from personnel at 217 points of sale/rental of framing nail guns in four areas of the country. Sales personnel had little understanding of risks associated with use of framing nail guns. Individuals who had used the tool and those working in construction outlets were more likely to be knowledgeable; even so, less than half understood differences in trigger/actuation systems. Consumers, including contractors purchasing for workers, cannot count on receiving accurate information from sales personnel regarding risks associated with use of these tools. The attitudes and limited knowledge of some sales personnel regarding these potentially deadly tools likely contributes to a culture accepting of injury. The findings demonstrate how influences on the culture of construction are not limited to workers, employers, or the places construction gets done. Copyright © 2011 Wiley-Liss, Inc.

Adopting technologies such as injection safety devices in healthcare settings can enhance injection safety. Developing guidelines for appropriate adoption of such technologies need to consider factors beyond evidence for their health effects. The objective of this study is to systematically review the published literature for evidence among healthcare workers and patients about knowledge, attitudes, beliefs, values, preferences, and feasibility in relation to the use of injection safety devices in healthcare settings. We included both qualitative and quantitative studies conducted with the general public, patients, and healthcare workers, administrators, or policy makers. We searched MEDLINE, EMBASE, CINHAL and CENTRAL. We used a duplicate and independent approach to title and abstract screening, full text screening, data abstraction and risk of bias assessment. Out of a total of 6568 identified citations, we judged fourteen studies as eligible for this systematic review. All these studies were surveys, conducted with healthcare workers in high-income countries. We did not identify any qualitative study, or a study of the general public, patients, healthcare administrators or policy makers. We did not identify any study assessing knowledge, or values assigned to outcomes relevant to injection safety devices. Each of the included studies suffered from methodological limitations, which lowers our confidence in their findings. Based on the findings of six studies, the injection safety devices were generally perceived as easy to use and as an improvement compared with conventional syringes. Some of these studies reported few technical problems while using the devices. In three studies assessing perceived safety, the majority of participants judged the devices as safe. Two studies reported positive perceptions of healthcare workers regarding patient tolerance of these injection safety devices. One study found that less than half the nurses felt comfortable using the insulin pens. Findings from four studies assessing preference and satisfaction were not consistent. This systematic review identified evidence that injection safety devices are generally perceived as easy to use, safe, and tolerated by patients. There were few reports of technical problems while using the devices and some discomfort by nurses using the insulin pens.
Use of cultural consensus analysis to evaluate expert feedback of median safety.
Kim, Tae-Gyu; Donnell, Eric T; Lee, Dongmin
2008-07-01
Cultural consensus analysis is a statistical method that can be used to assess participant responses to survey questions. The technique concurrently estimates the knowledge of each survey participant and estimates the culturally correct answer to each question asked, based on the existence of consensus among survey participants. The main objectives of this paper are to present the cultural consensus methodology and apply it to a set of median design and safety survey data that were collected using the Delphi method. A total of 21 Delphi survey participants were asked to answer research questions related to cross-median crashes. It was found that the Delphi panel had agreeable opinions with respect to the association of average daily traffic (ADT) and heavy vehicle percentage combination on the risk of cross-median crashes; relative importance of additional factors, other than ADT, median width, and crash history that may contribute to cross-median crashes; and, the relative importance of geometric factors that may be associated with the likelihood of cross-median crashes. Therefore, the findings from the cultural consensus analysis indicate that the expert panel selected to participate in the Delphi survey shared a common knowledge pool relative to the association between median design and safety. There were, however, diverse opinions regarding median barrier type and its preferred placement location. The panel showed a higher level of knowledge on the relative importance regarding the association of geometric factors on cross-median crashes likelihood than on other issues considered. The results of the cultural consensus analysis of the present median design and safety survey data could be used to design a focused field study of median safety.

Occupational hazards, exposure to blood and body fluids (BBF) accidents and safety precautions constitute an important public health issue. We assessed the prevalence and determinants of exposure to occupational hazards among nurses, and their knowledge of occupational safety precautions. In a cross-sectional study, we surveyed 332 nurses working in 4 hospitals, Nablus, West Bank, Palestine, by a questionnaire. Bivariate analysis tested the associations between ever exposure and the high likelihood of BBF exposure and the independent socio-demographic and occupational variables. Binary logistic regression analysis was used to assess the associations between the same two exposures and selected independent variables (those significant in the bivariate analysis). Prevalence of ever exposure to BBF was 51.7%, and was associated with working in private and charitable hospitals (OR 2.62, 2.68, respectively), having 4-6 family members (OR 0.52) and "nursing" being as one's top career choice at university (OR 0.48). The prevalence of high likelihood of BBF exposure was 62.2%, and was associated with working in charitable and private hospitals (OR 7.81, 2.43, respectively) and "nursing" being as one's top career choice (OR 0.57). Regarding knowledge, most respondents believed it is necessary to enact laws and regulations regarding occupational safety precautions, reported the use of sharps containers, immediate disinfection after an accident, reporting an accident, and using personal protective equipment. Nurses had adequate knowledge of the risks of their hospital work. Nevertheless, they exhibited high prevalence of exposure to BBF accidents. Future studies are needed to re-evaluate existing occupational safety guidelines in hospitals, establish monitoring and evaluation protocols for health care workers' adherence to the guidelines, and institute well-defined policies for reporting occupational injury incidents so these can be handled appropriately.
Sun safety in construction: a U.K. intervention study.
Houdmont, J; Madgwick, P; Randall, R
2016-01-01
Interventions to promote sun safety in the U.K. construction sector are warranted given the high incidence of skin cancer attributable to sun exposure relative to other occupational groups. To evaluate change in sun safety knowledge and practices among construction workers in response to an educational intervention. A baseline questionnaire was administered, followed by a bespoke sector-specific DVD-based intervention. At 12-month follow-up, participants completed a further questionnaire. Analyses were conducted on a sample of 120 workers (intervention group, n = 70; comparison group, n = 50). At follow-up, the proportion of intervention group participants that reported correct sun safety knowledge was not significantly greater than at baseline. However, the intervention group demonstrated significant positive change on 9 out of 10 behavioural measures, the greatest change being use of a shade/cover when working in the sun followed by regularly checking skin for moles or unusual changes. Exposure to this intervention was linked to some specific positive changes in construction workers' self-reported sun safety practices. These findings highlight the potential for educational interventions to contribute to tackling skin cancer in the UK construction sector. The findings support the development of bespoke educational interventions for other high-risk outdoor worker groups. © The Author 2015.

2013-04-01
In the first part of this work, the progress of Italian National Rules about dams design, construction and operation are presented to highlight the strong connection existing between the promulgation of new decrees, as a consequence of a dam accidents, and the necessity to prevent further loss of lives and goods downstream. Following the Gleno Dam failure (1923), a special Ministerial Committee wrote out the first Regulations and made the proposal to establish, within the High Council of Public Works, a special department that become soon the "Dam Service", with the tasks of control and supervision about construction and operation phases of the dams and their reservoirs. A different definition of tasks and the structure of Dam Service were provided in accordance with law n° 183/1989, which transferred all the technical services to the Office of the Prime Minister; the aim was to join the Dam Office with the Department for National Technical Services, with the objective of increasing the knowledge of the territory and promoting the study on flood propagation downstream in case of operations on bottom outlet or hypothetical dam-break. In fact, population living downstream is not ready to accept any amount of risk because has not a good knowledge of the efforts of experts involved in dam safety, both from the operators and from the safety Authority. So it's important to optimize all the activities usually performed in a dam safety program and improve the emergency planning as a response to people's primary needs and feeling about safety from Civil Protection Authority. In the second part of the work, a definition of risk is provided as the relationship existing between probability of occurrence and loss, setting out the range within to plan for prevention (risk mitigation), thanks to the qualitative assessment of the minimum safety level that is suited to assign funds to plan for Civil Protection (loss mitigation). The basic meaning of the reliability of a zoned earthfill dam is illustrated by defining the risk analysis during its construction and operation. A qualitative "Event Tree Analysis" makes clear with an example the probability of occurrence of the events triggered by an earthquake, and leads to a classification of the damage level. Finally, a System Dynamics (SD) approach is presented to investigate possibilities of a preventive planning in relationship to the risk, so that it's possible to establish shared procedures to achieve the correct management in any crisis phase. As a qualitative result of a SD application, figure 1 presents a flow-chart about a case study on the same dam so to illustrate the emergency planning in a step by step procedure according to the Regulations.

The Process-Based Mission Assurance - Knowledge Management System (PBMA-KMS) implemented at the National Aeronautics and Space Administration (NASA) focuses on the practical application of the knowledge management (KM) theory and is based on a systems engineering management approach coupled to a continual improvement and risk management philosophy. Not to be confused with an Agency mandate, an intense focus has been placed on grassroots input to the future of the product. By providing emphasis to both Agency safety and mission success objectives and individual users' needs, the PBMA-KMS team has been able to be both reactive to Agency requirements and proactive to the needs of the community.PBMA-KMS is an excellent case study on how to use new approaches to facilitate and integrate safety into the culture of an organization. Principle discussion topics include: • Overarching themes,• Tactical approaches,• Highlights of key functionalities, and• Agency KM approach of managed Darwinism.PBMA-KMS can show how, by providing top-level guidance along with the necessary tools and support, the organization not only receives immediate value, but the long-ranging benefits of a more experienced, effective, and engaged workforce.

Age-appropriate child restraints and rear seating dramatically reduce injury in vehicle crashes. Yet parents and caregivers struggle to comply with child passenger safety (CPS) recommendations, and frequently make mistakes when choosing and installing restraints. The purpose of this research was to evaluate various methods of framing CPS recommendations, and to examine the relative effectiveness on parents' knowledge, attitudes, and behavioral intentions related to best practices and proper use of child restraints. Emphasis framing is a persuasion technique that involves placing focus on specific aspects of the content in order to encourage or discourage certain interpretations of the content. A 5 (flyer group) X 2 (time) randomized experiment was conducted in which 300 parent participants answered a pre-survey, viewed one of four flyer versions or a no-education control version, and completed a post-survey. Surveys measured CPS knowledge, attitudes, perceptions of efficacy and risk, and behavioral intentions. The four flyers compared in this study all communicated the same CPS recommendations, but several versions were tested which each employed a different emphasis frame: (1) recommendations organized by the natural progression of seat types; (2) recommendations which focused on avoiding premature graduation; (3) recommendations which explained the risk-reduction rationale behind the information given; or (4) recommendations which were organized by age. In a fifth no-education (control) condition, participants viewed marketing materials. Analyses of covariance and pairwise comparisons indicated the risk-reduction rationale flyer outperformed other flyers for many subscales, and significantly differed from no-education control for the most subscales, including restraint selection, back seat knowledge, rear-facing knowledge and attitudes, total efficacy, overall attitudes, and stated intentions. This research provides insight for increasing caregiver understanding and compliance with CPS information. Recommendations for the field include communicating the rationale behind the information given, using behavior-based directives in headers, avoiding age-based headers, and incorporating back-seat positioning directives throughout.

Hutting, Nathan; Kerry, Roger; Coppieters, Michel W; Scholten-Peeters, Gwendolijne G M
2018-02-01
Manipulation and mobilisation of the cervical spine are well established interventions in the management of patients with headache and/or neck pain. However, their benefits are accompanied by potential, yet rare risks in terms of serious adverse events, including neurovascular insult to the brain. A recent international framework for risk assessment and management offers directions in the mitigation of this risk by facilitating sound clinical reasoning. The aim of this article is to critically reflect on and summarize the current knowledge about cervical spine manual therapy and to provide guidance for clinical reasoning for cervical spine manual therapy.

We based the Patient Safety Leadership Academy (PSLA) on the premise that improving management skills could improve patient safety and employee satisfaction. Fellows completed baseline surveys on leadership skills knowledge, patient safety knowledge, and program goals. They completed the same surveys 7 months later at the final PSLA session. The fellows also completed a survey assessing how PSLA improved expertise and comparing PSLA to other patient safety learning opportunities. Matched pairs t tests were used to compare baseline and postprogram results. Baseline scores indicated appropriateness of focusing on leadership, with average leadership knowledge (2.48) significantly lower than patient safety knowledge (3.22). For patient safety, postprogram results were significant for 8 of 10 questions. All results were significant for leadership. Fellows also rated skills covered by the curriculum on a scale of 1 to 10. For all areas, the median score for knowledge gained was 7. When compared with other patient safety learning experiences, participants rated PSLA as 4 or 5, where 1 indicated the other experience much more valuable and 5 much more valuable. PSLA demonstrates that leadership skills are perceived as important by physicians and managers in surgical areas. This study demonstrated that a leadership skills approach to patient safety training could improve knowledge in specific leadership areas and general patient safety.
Electronic Health Record Tools to Care for At-Risk Older Drivers: A Quality Improvement Project.
Casey, Colleen M; Salinas, Katherine; Eckstrom, Elizabeth
2015-06-01
Evaluating driving safety of older adults is an important health topic, but primary care providers (PCP) face multiple barriers in addressing this issue. The study's objectives were to develop an electronic health record (EHR)-based Driving Clinical Support Tool, train PCPs to perform driving assessments utilizing the tool, and systematize documentation of assessment and management of driving safety issues via the tool. The intervention included development of an evidence-based Driving Clinical Support Tool within the EHR, followed by training of internal medicine providers in the tool's content and use. Pre- and postintervention provider surveys and chart review of driving-related patient visits were conducted. Surveys included self-report of preparedness and knowledge to evaluate at-risk older drivers and were analyzed using paired t-test. A chart review of driving-related office visits compared documentation pre- and postintervention including: completeness of appropriate focused history and exam, identification of deficits, patient education, and reporting to appropriate authorities when indicated. Data from 86 providers were analyzed. Pre- and postintervention surveys showed significantly increased self-assessed preparedness (p < .001) and increased driving-related knowledge (p < .001). Postintervention charts showed improved documentation of correct cognitive testing, more referrals/consults, increased patient education about community resources, and appropriate regulatory reporting when deficits were identified. Focused training and an EHR-based clinical support tool improved provider self-reported preparedness and knowledge of how to evaluate at-risk older drivers. The tool improved documentation of driving-related issues and led to improved access to interdisciplinary care coordination.

Objectives Falls from heights are a leading cause of mortality and morbidity in the construction industry, especially among inexperienced workers. We surveyed apprentice carpenters to identify individual and organizational factors associated with falls from heights. Methods We developed a 72-item fall prevention survey with multiple domains including fall experience, fall prevention knowledge, risk perceptions, confidence in ability to prevent falls, training experience, and perceptions of the safety climate and crew safety behaviors. We administered the questionnaire to apprentice carpenters in this cross-sectional study. Results Of the 1,025 respondents, 51% knew someone who had fallen from height at work and 16% had personally fallen in the past year, with ladders accounting for most of the falls. Despite participation in school-based and on-the-job training, fall prevention knowledge was poor. Ladders were perceived as low risk and ladder training was rare. Apprentices reported high levels of unsafe fall-related behaviors on their work crews. Apprentices working residential construction were more likely to fall than those working commercial construction, as were apprentices working on crews with fewer senior carpenters to provide mentorship, and those reporting more unsafe behaviors among fellow workers. Conclusions Despite participation in a formal apprenticeship program, many apprentices work at heights without adequate preparation and subsequently experience falls. Apprenticeship programs can improve the timing and content of fall prevention training. This study suggests that organizational changes in building practices, mentorship, and safety culture must also occur in order to decrease worker falls from heights. PMID:19953214
Factors influencing oncology nurses' use of hazardous drug safe-handling precautions.
Polovich, Martha; Clark, Patricia C
2012-05-01
To examine relationships among factors affecting nurses' use of hazardous drug (HD) safe-handling precautions, identify factors that promote or interfere with HD precaution use, and determine managers' perspectives on the use of HD safe-handling precautions. Cross-sectional, mixed methods; mailed survey to nurses who handle chemotherapy and telephone interviews with managers. Mailed invitation to oncology centers across the United States. 165 nurses who reported handling chemotherapy and 20 managers of nurses handling chemotherapy. Instruments measured the use of HD precautions and individual and organizational factors believed to influence precaution use. Data analysis included descriptive statistics and hierarchical regression. Manager interview data were analyzed using content analysis. Chemotherapy exposure knowledge, self-efficacy, perceived barriers, perceived risk, interpersonal influences, and workplace safety climate. Nurses were well educated, experienced, and certified in oncology nursing. The majority worked in outpatient settings and administered chemotherapy to an average of 6.8 patients per day. Exposure knowledge, self-efficacy for using personal protective equipment, and perceived risk of harm from HD exposure were high; total precaution use was low. Nurse characteristics did not predict HD precaution use. Fewer barriers, better workplace safety climate, and fewer patients per day were independent predictors of higher HD precaution use. HD handling policies were present, but many did not reflect current recommendations. Few managers formally monitored nurses' HD precaution use. Circumstances in the workplace interfere with nurses' use of HD precautions. Interventions should include fostering a positive workplace safety climate, reducing barriers, and providing appropriate nurse-patient ratios.

To achieve the goal of safe care for mothers and infants during labor and birth, Catholic Healthcare Partners (CHP; Cincinnati) conducted on-site risk assessments at the 16 hospitals with perinatal units in 2004-2005, with follow-up visits in 2006 through 2008. ON-SITE RISK ASSESSMENTS: In addition to assessing overall organizational risk, the assessments provided each hospital a gap analysis demonstrating up-to-date and outdated practices and strategies and resources necessary to make all practices consistent with current evidence and national guidelines and standards. CRITICAL ASPECTS OF CLINICAL CARE: Review of claims and near-miss data indicate that fetal assessment, labor induction, and second-stage labor care comprise the majority of risk of perinatal harm. Therefore, these clinical areas were the focus of strategies to promote safety. To promote consistency in knowledge and practice, in 2004 a variety of strategies were recommended, including interdisciplinary fetal monitoring education and routine medical record reviews to monitor ongoing adherence to appropriate practice and documentation. Success in implementing essential structural and process components of the perinatal patient safety program have resulted in improvement from 2003 to 2008 in specific outcomes for the 16 perinatal units surveyed, including reduction of perinatal harm, number of claims, and costs of claims. The program continues to evolve with modifications as needed as more evidence becomes available to guide best perinatal practices and new guidelines/standards are published. A patient safety program guided and supported by a health care system can result in safer clinical environments in individual hospitals and in decreased risk of preventable perinatal harm and liability costs.

A descriptive-correlational study of biosolids recycling was conducted in the south-eastern United States to assess current knowledge, attitudes and risk perceptions of participants in two communities that land apply biosolids as part of their waste management programs. One community, Amelia County VA, has been outspoken against biosolids recycling in the past, whereas the second community, Knoxville, TN region, has voiced few concerns about biosolids recycling. Additionally, gender differences within the entire study population were assessed. A 45-question telephone survey, utilizing a 4-point Likert scale, was developed and administered to 311 randomly selected adults in the two regions. Commonalities identified during the study revealed key risk perceptions by the public regarding biosolids regulations, treatment, and application. Given current perceptions and knowledge, respondents felt that the benefits derived from biosolids recycling do not offset the perceived health and safety risks. However, as distance between application and personal property increased, a decrease in opposition of biosolids reuse became evident for all respondents. Survey participants were dissatisfied with the level of stakeholder involvement in research and decision-making processes concerning biosolids. The outspoken Amelia County residents perceived greater health risks due to inadequate treatment of biosolids and odorous emissions during the application process than the less engaged Knox Metro respondents. Significant gender differences were observed with sampled females perceiving greater risks to health and safety from biosolids recycling than males. There was also indication that decisions and risks were not sufficiently communicated to the public, leading to respondents being inadequately informed about biosolids land application in both communities. Community-specific outreach programs must address these public risk perceptions and the differences in perception caused by gender and issue awareness to assist solid waste managers in developing and implementing successful biosolids land application systems that are acceptable to the public.

FoodWiki: a Mobile App Examines Side Effects of Food Additives Via Semantic Web.
Çelik Ertuğrul, Duygu
2016-02-01
In this article, a research project on mobile safe food consumption system (FoodWiki) is discussed that performs its own inferencing rules in its own knowledge base. Currently, the developed rules examines the side effects that are causing some health risks: heart disease, diabetes, allergy, and asthma as initial. There are thousands compounds added to the processed food by food producers with numerous effects on the food: to add color, stabilize, texturize, preserve, sweeten, thicken, add flavor, soften, emulsify, and so forth. Those commonly used ingredients or compounds in manufactured foods may have many side effects that cause several health risks such as heart disease, hypertension, cholesterol, asthma, diabetes, allergies, alzheimer etc. according to World Health Organization. Safety in food consumption, especially by patients in these risk groups, has become crucial, given that such health problems are ranked in the top ten health risks around the world. It is needed personal e-health knowledge base systems to help patients take control of their safe food consumption. The systems with advanced semantic knowledge base can provide recommendations of appropriate foods before consumption by individuals. The proposed FoodWiki system is using a concept based search mechanism that performs on thousands food compounds to provide more relevant information.
Advances on the Failure Analysis of the Dam-Foundation Interface of Concrete Dams.

Failure analysis of the dam-foundation interface in concrete dams is characterized by complexity, uncertainties on models and parameters, and a strong non-linear softening behavior. In practice, these uncertainties are dealt with a well-structured mixture of experience, best practices and prudent, conservative design approaches based on the safety factor concept. Yet, a sound, deep knowledge of some aspects of this failure mode remain unveiled, as they have been offset in practical applications by the use of this conservative approach. In this paper we show a strategy to analyse this failure mode under a reliability-based approach. The proposed methodology of analysis integrates epistemic uncertainty on spatial variability of strength parameters and data from dam monitoring. The purpose is to produce meaningful and useful information regarding the probability of occurrence of this failure mode that can be incorporated in risk-informed dam safety reviews. In addition, relationships between probability of failure and factors of safety are obtained. This research is supported by a more than a decade of intensive professional practice on real world cases and its final purpose is to bring some clarity, guidance and to contribute to the improvement of current knowledge and best practices on such an important dam safety concern.

Can stress in farm animals increase food safety risk?
Rostagno, Marcos H
2009-09-01
All farm animals will experience some level of stress during their lives. Stress reduces the fitness of an animal, which can be expressed through failure to achieve production performance standards, or through disease and death. Stress in farm animals can also have detrimental effects on the quality of food products. However, although a common assumption of a potential effect of stress on food safety exists, little is actually known about how this interaction may occur. The aim of this review was to examine the current knowledge of the potential impact of stress in farm animals on food safety risk. Colonization of farm animals by enteric pathogens such as Escherichia coli O157:H7, Salmonella, and Campylobacter, and their subsequent dissemination into the human food chain are a major public health and economic concern for the food industries. This review shows that there is increasing evidence to demonstrate that stress can have a significant deleterious effect on food safety through a variety of potential mechanisms. However, as the impact of stress is difficult to precisely determine, it is imperative that the issue receives more research attention in the interests of optimizing animal welfare and minimizing losses in product yield and quality, as well as to food safety risks to consumers. While there is some evidence linking stress with pathogen carriage and shedding in farm animals, the mechanisms underlying this effect have not been fully elucidated. Understanding when pathogen loads on the farm are the highest or when animals are most susceptible to infection will help identifying times when intervention strategies for pathogen control may be most effective, and consequently, increase the safety of food of animal origin.

This is, to the best of our knowledge, the first occupational health study in Greek fishing. The aim of the study is to determine the risks for health and safety in Greek fisheries workers by exploring their health status and the health risk factors present in their occupational environment, thus providing a current baseline for further research in the future and for documentation of the needs for prevention. A questionnaire pilot study was carried out in a random sample of 100 Greek fishermen. Twenty-eight per cent (28%) had experienced at least one injury, of which half caused more than one day absence, while 14% had a near drowning experience. The health risks factors studied include excessive weight, cardiovascular incidents and dermatological, musculoskeletal, respiratory, hearing, stress, and anxiety problems. The occupational health risk factors include alcohol, fatty food consumption, smoking, and lack of physical exercise. The health effects observed are causally related to diet, smoking, and exercise, which in turn relate to the specific working conditions and culture in small-scale fishing that need to be taken into consideration in prevention programmes. The results are comparable with international fisheries experience, mainly from Poland, Denmark, and Turkey.

Engineered nanomaterials significantly entered commerce at the beginning of the 21st century. Concerns about serious potential health effects of nanomaterials were widespread. Now, approximately 15 years later, it is worthwhile to take stock of research and efforts to protect nanomaterial workers from potential risks of adverse health effects. This article provides and examines timelines for major functional areas (toxicology, metrology, exposure assessment, engineering controls and personal protective equipment, risk assessment, risk management, medical surveillance, and epidemiology) to identify significant contributions to worker safety and health. The occupational safety and health field has responded effectively to identify gaps in knowledge and practice, but further research is warranted and is described. There is now a greater, if imperfect, understanding of the mechanisms underlying nanoparticle toxicology, hazards to workers, and appropriate controls for nanomaterials, but unified analytical standards and exposure characterization methods are still lacking. The development of control-banding and similar strategies has compensated for incomplete data on exposure and risk, but it is unknown how widely such approaches are being adopted. Although the importance of epidemiologic studies and medical surveillance is recognized, implementation has been slowed by logistical issues. Responsible development of nanotechnology requires protection of workers at all stages of the technological life cycle. In each of the functional areas assessed, progress has been made, but more is required.

The aim of the study was to evaluate the knowledge and attitudes on food hygiene in seafarers. The study was conducted using an anonymous questionnaire presented to the workers of 7 tankers of an Italian shipping company (Finaval S.p.A.). As a reference, the analysis was extended to office employees of the same firm. Data were divided according to the rank of seafarers to assess possible differences in perceiving the risk. Overall knowledge on food safety concept was not high among seafarers. In general, galley and catering workers group provided a lower percentage of correct answers than other crew members. Foodservices staff revealed little awareness of the risks linked with handling food and their perception of risk of disease transmission through food was low. Answers about risk related to specific food (eggs and fish) showed that knowledge about these problems was less than satisfactory. Moreover, the percentage of 'I don't know' answers was high. These findings suggest that this personnel is aware of the right stepsof health protection in terms of food hygiene, but does not understand why it is necessary. Galley and catering group workers were not the most informed about food hygiene problems.This highlights the need to hire qualified personnel of the food industry on board ships. All those working inthe food service area should be properly trained on food hygiene. Seafarers should be the target of specificinformative campaigns about health risks linked with aliments, possible consequences of it and also oneson how to minimise the exposure to potentially dangerous agents/behaviours during travel/life at sea.

Carbon monoxide (CO) poisonings in the United States consistently occur when residents improperly use portable gasoline-powered generators and other tools following severe storms and power outages. However, protective behaviors-such as installing CO alarms and placing generators more than 20 feet away from indoor structures-can prevent these poisonings. This study identified knowledge, attitudes, and beliefs that lead consumers to adopt risk and protective behaviors for storm-related CO poisoning and post-storm generator use. Four focus groups (32 participants in total) were conducted with generator owners in winter and summer storm-prone areas to explore home safety, portable generator use, CO poisoning knowledge, and generator safety messages. Discussions were transcribed, and findings analyzed using an ordered meta-matrix approach. Although most generator owners were aware of CO poisoning, many were unsure what constitutes a safe location for generator operation and incorrectly stated that enclosed areas outside the home-such as attached garages, sheds, and covered porches-were safe. Convenience and access to appliances often dictated generator placement. Participants were receptive to installing CO alarms in their homes but were unsure where to place them. These findings suggest a deficit in understanding how to operate portable generators safely and a need to correct misconceptions around safe placement. In terms of behavioral price, the simple installation and maintenance of inexpensive CO alarms may be the most important strategy for ultimately protecting homes from both storm-related and other CO exposures.

This paper is one of several prepared under the project "Food Safety In Europe: Risk Assessment of Chemicals in Food and Diet" (FOSIE), a European Commission Concerted Action Programme, organised by the International Life Sciences Institute, Europe (ILSI). The aim of the FOSIE project is to review the current state of the science of risk assessment of chemicals in food and diet, by consideration of the four stages of risk assessment, that is, hazard identification, hazard characterisation, exposure assessment and risk characterisation. The contribution of animal-based methods in toxicology to hazard identification of chemicals in food and diet is discussed. The importance of first applying existing technical and chemical knowledge to the design of safety testing programs for food chemicals is emphasised. There is consideration of the presently available and commonly used toxicity testing approaches and methodologies, including acute and repeated dose toxicity, reproductive and developmental toxicity, neurotoxicity, genotoxicity, carcinogenicity, immunotoxicity and food allergy. They are considered from the perspective of whether they are appropriate for assessing food chemicals and whether they are adequate to detect currently known or anticipated hazards from food. Gaps in knowledge and future research needs are identified; research on these could lead to improvements in the methods of hazard identification for food chemicals. The potential impact of some emerging techniques and toxicological issues on hazard identification for food chemicals, such as new measurement techniques, the use of transgenic animals, assessment of hormone balance and the possibilities for conducting studies in which common human diseases have been modelled, is also considered.
Understanding drug targets: no such thing as bad news.
Roberts, Ruth A
2018-05-24
How can small-to-medium pharma and biotech companies enhance the chances of running a successful drug project and maximise the return on a limited number of assets? Having a full appreciation of the safety risks associated with proposed drug targets is a crucial element in understanding the unwanted side-effects that might stop a project in its tracks. Having this information is necessary to complement knowledge about the probable efficacy of a future drug. However, the lack of data-rich insight into drug-target safety is one of the major causes of drug-project failure today. Conducting comprehensive target-safety reviews early in the drug discovery process enables project teams to make the right decisions about which drug targets to take forward.

Psychosocial risks at work are the challenge facing the occupational health and safety protection. They are seen as a threat to the employees' health and functioning. They also contribute to negative outcomes in the organizations. The study was focused on the assessment of employees' knowledge of occupational stressors, their consequences and preventive measures. The assessment results will help in the development of an educational program aimed at increasing awareness of occupational stress among employees. 210 employees participated in the study. By the mean of survey "Psychosocial Risks at Work-place" the information on the respondents' knowledge of occupational stress issues was collected. Stressors intrinsic to the job (mostly work overload) were recognized as best known to employees (67.62%). The second place was occupied by stressors originating from interpersonal relationships at work (51.9% of respondents pointed out that problem). Almost no one (0.48%) mentioned home-work interference as a source of occupational stress. According to the respondents' opinion, occupational stress mostly results in health decline. The employees who participated in the study believe that the employer (13.81%) or the superior (19.05%) is responsible for psychosocial risks prevention at the work place. Almost a half of subjects (46.67%) did not know whether there are any law regulations on psychosocial risk at work in Poland. The respondents showed an average level of knowledge of psychosocial risk at the work place and knew almost nothing about occupational stress prevention. The results of the study point to the need for systematic education of employees about stress and stress related issues.
Kitchen safety in hospitals: practices and knowledge of food handlers in istanbul, Turkey.
Ercan, Aydan; Kiziltan, Gul
2014-10-01
This study was designed to identify the practices and knowledge of food handlers about workplace safety in hospital kitchens (four on-premises and eight off-premises) in Istanbul. A kitchen safety knowledge questionnaire was administered and a kitchen safety checklist was completed by dietitians. The mean total scores of the on-premise and off-premise hospital kitchens were 32.7 ± 8.73 and 37.0 ± 9.87, respectively. The mean scores for the items about machinery tools, electricity, gas, and fire were lower in off-premise than on-premise hospital kitchen workers. The kitchen safety knowledge questionnaire had five subsections; 43.7% of the food handlers achieved a perfect score. Significant differences were found in the knowledge of food handlers working in both settings about preventing slips and falls (p < .05). Significant relationships were found between marital status, education level, and kitchen safety knowledge of the food handlers (p < .05). Copyright 2014, SLACK Incorporated.

For health care systems in recent years, patient safety has increasingly become a priority issue. National and international strategies have been considered to attempt to overcome the most prominent hazards while patients are receiving health care. Thereby, clinical risk management (CRM) plays a dominant role in enabling the identification, analysis, and management of potential risks. CRM implementation into routine procedures within complex hospital organizations is challenging, as in the past, organizational change strategies using a top-down approach have often failed. Therefore, one of our main objectives was to educate a certain number of risk managers in facilitating CRM using a bottom-up approach. To achieve our primary purpose, five project strands were developed, and consequently followed, introducing CRM: corporate governance, risk management (RM) training, CRM process, information, and involvement. The core part of the CRM process involved the education of risk managers within each organizational unit. To account for the size of the existing organization, we assumed that a minimum of 1 % of the workforce had to be trained in RM to disseminate the continuous improvement of quality and safety. Following a roll-out plan, CRM was introduced in each unit and potential risks were identified. Alongside the changes in the corporate governance, a hospital-wide CRM process was introduced resulting in 158 trained risk managers correlating to 2.0 % of the total workforce. Currently, risk managers are present in every unit and have identified 360 operational risks. Among those, 176 risks were scored as strategic and clustered together into top risks. Effective meeting structures and opportunities to share information and knowledge were introduced. Thus far, 31 units have been externally audited in CRM. The CRM approach is unique with respect to its dimension; members of all health care professions were trained to be able to identify potential risks. A network of risk managers supported the centrally coordinated CRM process. There is a strong commitment among management, academia, clinicians, and administration to foster cooperation. The introduction of CRM led to a visible shift with regard to patient safety culture throughout the entire organization. Still, there is a long way to go to keep people engaged in CRM and work on national and international patient safety initiatives to continuously decrease potential hazards.
[Safety profile of zolpidem: two studies of 3805 patients by Swiss practitioners].

Evaluation and treatment of insomnia are frequent procedures in the physician's everyday practice, since many patients seek medical treatment for this condition. Knowledge of pharmacological therapeutical alternatives is therefore decisive, in order to identify the most efficaceous and safe therapy for the patient among the available hypnotics. The short-acting hypnotic zolpidem has been investigated in Switzerland in two multicenter safety studies in ambulatory practice. In the first study 8.9% (n = 125 of 1,972 treated patients), and in the second 7.2% of the patients (n = 175 of 1,833 treated patients) reported an adverse event. The most frequent events were related to the central nervous system (CNS) (somnolence, headache, confusion, vertigo); gastrointestinal and cutaneous symptoms were the most frequent non CNS-dependent effects. New, unknown or serious adverse events were not found and no specific risk factor or population at risk was identified. The safety profile of zolpidem is consistent with its known pharmacological properties, the results of previous clinical trials and the international experience obtained in large patients groups.

The impacts of adverse events related to geological hazards are unevenly distributed among communities and groups of individuals concentrated in restricted workplaces. Their consequent safety level is the result of differential exposures to these events and of diversified levels of preparation to them. Nowadays, the exposure and coping ability as co-determinants of people's safety are of particular interest for institutions managing the schools systems. According to the disaster risk reduction experts, the geo-hydrological processes can be mitigated with knowledge and planning, physical and environmental protection measures, and response preparedness. UNISDR is promoting a global culture of safety and resilience through the integration of disaster risk reduction in school curricula. The Comprehensive School Safety (CSS) framework is intended to advance the goals of the Worldwide Initiative for Safe Schools and the Global Alliance for Disaster Risk Reduction and Resilience in the Education Sector, and to promote school safety as a priority area of post-2015 frameworks for sustainable development, risk reduction and resilience. In Italy, according the latest ministerial survey (June 2010), there are 41,902 school buildings. Their alarming condition in terms of safety for their daily occupants is reflected by 39 fatalities ascribable to structural failures in the last 21 years. In 95% of these cases victims are a sad tribute due to natural phenomena. A rigorous evaluation of the total risk of a school building, as defined by the well known risk equation (R=HxVxE), would require a complete probability density function describing the exposure to specific types of events of all the pupils and personnel in the school. In addition, the probability that the inhabitants are present in the school during an event should be estimated depending on the time of day, day of week, or month of the year, as well as on local holiday schedules. The inclusion of resilience as a component of risk allows us to refine the risk awareness, focusing attention on the cultural and social meaning of risk as a shared practice among communities that are potentially at risk. This project developed a method for assessing school hazard exposure (landslide, seismic, flood) and structural fragility/safe learning facilities (seismic response, dampness, plan configuration) which is non-invasive, fairly quick and objective. This tool, which is based on the GSC (Geohazard Safety Classification) definition, was tested in central Italy and optimized for a very wide variety of situations, so that it may be exported in schools (or in similar working places) of other geographical areas. The GSC was obtained as the complementary to one of the Index of Geohazard Impact (IGI), calculated modifying the equation of the specific risk, taking into account also the resilience as a damper, amplifier or invariant of the specific risk itself (IGI=max(HixVi)/rho). The variables of this new equation (hazard, vulnerability and resilience) can be quantified on the basis of ancillary data (thematic maps), results of the data processing of field surveys (seismic noise measure according to the H/V technique, thermographic images, GPS surveys) and the answers to an online questionnaire implemented on purpose.

Persons with a past episode of self-harm or severe suicidal ideation are at elevated risk of self-harm as well as dying by suicide. It is well established that suicidal ideation fluctuates over time. Previous studies have shown that a personal safety plan can assist in providing support, when a person experiences suicide ideation, and help seeking professional assistance if needed. The aim of the trial is to determine whether a newly developed safety mobile app is more effective in reducing suicide ideation and other symptoms, compared to a safety plan on paper. The trial is designed as a two-arm, observer-blinded, parallel-group randomized clinical superiority trial, where participants will either receive: (1) Experimental intervention: the safety plan provided as the app MyPlan, or (2) Treatment as Usual: the safety plan in the original paper format. Based on a power calculation, a total of 546 participants, 273 in each arm will be included. They will be recruited from Danish Suicide Prevention Clinics. Both groups will receive standard psychosocial therapeutic care, up to 8-10 sessions of supportive psychotherapy. Primary outcome will be reduction in suicide ideation after 12 months. Follow-up interviews will be conducted at 3, 6, 9, and 12 months after date of inclusion. A safety plan is a mandatory part of the treatment in the Suicide Prevention Clinics in Demark. There are no studies investigating the effectiveness of a safety plan app compared to a safety plan on paper on reducing suicide ideation in patients with suicide ideation and suicidal behavior. The trial will gain new knowledge of whether modern technology can augment the effects of traditional personalized safety planning. ClinicalTrials.gov, NCT02877316 . Registered on 19 August 2016.

Knowledge has been known as a key element in developing support and perception by the public towards any new policy by the government, including the development of nuclear energy. The success of the policy is mainly dependent on public support which is related to the perception cultivated by the knowledge that is already held by the people. A public survey was conducted between 14 March 2016 to 10 May 2016 focusing on the Malaysian public acceptance and perception towards the implementation of nuclear energy in Malaysia (n=1438). This research was aimed on the research question which is `Does the level of general knowledge and education regarding nuclear energy in Malaysia influence the acceptance and support of the people to develop nuclear technology?'. These finding suggest that open discourse is a must even at the initial stages of developing a Nuclear Power Plant (NPP) program, which will touch on a few points that will assist to society's knowledge and understanding towards nuclear energy from the aspects of management, safety, radioactive waste, impact on economic competitiveness as well as the benefits and risks regarding the development of NPP. By increasing the knowledge regarding nuclear power and radioactive waste, perception towards the pros of NPP as well as the conviction towards its safety can be increased. It is suggested for the parties involved to use the latest approach of information technology as a way to provide the most effective medium of information dissemination to the public.

It is essential for drivers employed in the formal sector to have good knowledge of road safety in order to safeguard their lives and those of the staff they are employed to drive. The study was conducted to determine the effect of a road safety education intervention on road safety knowledge of drivers employed in the University of Ibadan, Nigeria. A quasi-experimental study of 98 intervention and 78 control drivers selected using a cluster sampling technique was conducted. The intervention comprised a two-day training on road safety and first aid. The drivers' knowledge of road safety was measured at baseline, immediately and 4-months post-intervention. Aggregate scores of road safety knowledge were computed giving minimum and maximum obtainable scores of 0 and 16 respectively. Change in mean scores over the three measurement periods was assessed using Repeated Measures Analysis of Variance (ANOVA). Independent t-test was used to compare the scores between intervention and control drivers at each of the assessment periods. Twenty-nine drivers did not complete the study (attrition rate = 16.5%). At baseline, mean road safety knowledge scores for the intervention and control drivers were 12.7±2.2 and 12.9± 2.3 (p = 0.510) respectively. Immediately and four months post intervention, the scores of the intervention drivers were 13.8±1.9 and 12.8±1.6; while scores for the controls were 13.3±2.0 and 13.2±1.8. Repeated measures ANOVA revealed that the increase in knowledge over the three assessment periods was not statistically significant. The intervention resulted in an initial increase in road safety knowledge of the intervention drivers. However, this was not sustained to the forth month post-intervention. This finding suggests periodic refresher trainings to sustain the knowledge acquired.

This paper is based on the report following the National Research Agenda Meeting on Mental Health, Justice, and Safety held in Montreal on November 19, 2014, which convened academics; health, social, and legal professionals; and people with lived experience of mental illness from across Canada. The goal was to identify research priorities addressing relevant knowledge gaps and research strategies that can translate into public policy action and improvements in evidence-based services. Participants identified key challenges: (1) inadequate identification and response to needs by civil mental health services and frontline law enforcement, (2) limited specialized resources in forensic and correctional settings, (3) fragmented care and gaps between systems, (4) limited resources for adequate community reintegration, and (5) poor knowledge transfer strategies as obstacles to evidence-based policies. Knowledge gaps were identified in epidemiology and risk reduction, frontline training and programs, forensic and correctional practices, organizations and institutions, knowledge transfer, and rehabilitation. Finally, participants identified potential sources of support to conduct real time research with regard to data collection and sharing. The findings represent a roadmap for how forensic mental health systems can best proceed to address current challenges through research and practice initiatives, drawing from lived, clinical and research experiences of a multidisciplinary group of experts.

To explore the level of Listeria awareness among pregnant women attending antenatal services and to gain a better understanding of women's knowledge of Listeria risk and factors that affect their practice in this regard. This was a cross-sectional study carried out from April to November 2006 using a convenience sample of pregnant women attending antenatal clinics/classes in one private and two major public hospitals in South Eastern Sydney and Illawarra Area Health Services, New South Wales. Women were asked to participate by completing a self-administered questionnaire based on the standard food safety recommendations for pregnant women to avoid Listeria infection. The association between different socio-demographic variables and Listeria knowledge, and related food practices, were investigated using bivariate and multivariate analysis. Nearly half of the 586 respondents had received some kind of information on Listeria prevention. The main channel for obtaining information was social environment. More than 57% had an incomplete knowledge of foods with high Listeria risk, and approximately 25% continued the consumption of these foods with a relatively high frequency. A strong association was found between women's knowledge and their practice. Lower education and household income, unplanned pregnancy and non-English-speaking background were associated with incomplete knowledge and more frequent consumption of at-risk foods. The provision of advice on Listeria prevention appears to be insufficient during prenatal consultations early in pregnancy and needs to be improved as an essential component of these services.

Projecting cancer risks from exposure to space radiation is highly uncertain because of the absence of data for humans and because of the limited radiobiology data available for estimating late effects from the high-energy and charge (HZE) ions present in the galactic cosmic rays (GCR). Cancer risk projections involve many biological and physical factors, each of which has a differential range of uncertainty due to the lack of data and knowledge. We discuss an uncertainty assessment within the linear-additivity model using the approach of Monte Carlo sampling from subjective error distributions that represent the lack of knowledge in each factor to quantify the overall uncertainty in risk projections. Calculations are performed using the space radiation environment and transport codes for several Mars mission scenarios. This approach leads to estimates of the uncertainties in cancer risk projections of 400-600% for a Mars mission. The uncertainties in the quality factors are dominant. Using safety standards developed for low-Earth orbit, long-term space missions (>90 days) outside the Earth's magnetic field are currently unacceptable if the confidence levels in risk projections are considered. Because GCR exposures involve multiple particle or delta-ray tracks per cellular array, our results suggest that the shape of the dose response at low dose rates may be an additional uncertainty for estimating space radiation risks.

Background and Aims: Unintentional acetaminophen overdose remains the leading cause of acute liver failure in the United States. Patients with underlying liver disease are at higher risk of poor outcomes from acetaminophen overdose. Limited knowledge of acetaminophen may be a preventable contributor to elevated rates of overdose and thus acute liver failure. The purpose of this study is to assess knowledge of acetaminophen dosing and presence of acetaminophen in common combination products in patients with liver disease. Methods: We performed a cross-sectional study of patients with liver disease at the Pfleger Liver Institute at the University of California, Los Angeles between June 2015 and August 2016. Patients completed a demographic questionnaire and an acetaminophen knowledge survey. Additional information was obtained from the medical record. Results: Of 401 patients with liver disease, 30 (15.7%) were able to correctly identify that people without liver disease can safely take up to 4 g/day of acetaminophen. The majority of patients (79.9%-86.8%) did not know that Norco® (hydrocone/acetaminophen), Vicodin® (hydrocone/acetaminophen) and Percocet® (oxycodone/acetaminophen) contained acetaminophen. Only 45.3% of the patients knew that Tylenol® #3 contained acetaminophen. Conclusions: We conclude that patients with liver disease have critically low levels of knowledge of acetaminophen, putting them at risk both of acetaminophen overdose, as well as undermedication, and inadequate management of chronic pain. We recommend an increase in education efforts regarding acetaminophen dosage and its safety in the setting of liver disease. Increasing education for those at risk of low acetaminophen knowledge is essential to minimizing acetaminophen overdose rates and optimizing pain management.

Intentions and knowledge shaping local safety policy: A comparison of two Swedish cities.
Hanberger, Anders; Lundström, Ulf; Mårald, Gunilla
2015-12-01
This article explores how intentions and knowledge shape two Swedish cities' local safety policy (LSP). The applied framework is derived from the integration of governance and implementation research and the theory of knowledge and its use. The study shows that LSPs are shaped by a mix of intentions and different kinds of knowledge, and intentions and knowledge interplay and intertwine in many ways. Key-persons construct LSPs when they work out solutions to urgent safety problems and take departure in the local context, its pre-conditions, and their experience-based and professional knowledge. The state governs LSP softly through management by objectives in the background, but more often key-actor intentions and commitments, local safety problems, and events initiated and influenced LSPs. The article contributes to a better understanding of conditions for LSPs in multi-level governance. The article can be used to improve governance, identify implementation problems and knowledge needs that will improve LSPs and the overall safety situation in the community. The study has implications for how LSPs should be evaluated; many different evaluation criteria can be appropriate, such as relevance, legitimacy, achievement of key actors' objectives, sustainability of policy solutions, and creation of a local safety culture.

Full scale fire testing complemented by computer modelling has provided significant know how about the risk, prevention and suppression of fire in terrestrial systems (cars, ships, planes, buildings, mines, and tunnels). In comparison, no such testing has been carried out for manned spacecraft due to the complexity, cost and risk associated with operating a long duration fire safety experiment of a relevant size in microgravity. Therefore, there is currently a gap in knowledge of fire behaviour in spacecraft. The entire body of low-gravity fire research has either been conducted in short duration ground-based microgravity facilities or has been limited to very small fuel samples. Still, the work conducted to date has shown that fire behaviour in low-gravity is very different from that in normal-gravity, with differences observed for flammability limits, ignition delay, flame spread behaviour, flame colour and flame structure. As a result, the prediction of the behaviour of fires in reduced gravity is at present not validated. To address this gap in knowledge, a collaborative international project, Spacecraft Fire Safety, has been established with its cornerstone being the development of an experiment (Fire Safety 1) to be conducted on an ISS resupply vehicle, such as the Automated Transfer Vehicle (ATV) or Orbital Cygnus after it leaves the ISS and before it enters the atmosphere. A computer modelling effort will complement the experimental effort. Although the experiment will need to meet rigorous safety requirements to ensure the carrier vehicle does not sustain damage, the absence of a crew removes the need for strict containment of combustion products. This will facilitate the possibility of examining fire behaviour on a scale that is relevant to spacecraft fire safety and will provide unique data for fire model validation. This unprecedented opportunity will expand the understanding of the fundamentals of fire behaviour in spacecraft. The experiment is being developed by an international topical team that is collaboratively defining the experiment requirements and performing supporting analysis, experimentation and technology development. This paper presents the objectives, status and concept of this project.

To address this gap in knowledge, a collaborative international project, Spacecraft Fire Safety, has been established with its cornerstone being the development of an experiment (Fire Safety 1) to be conducted on an ISS resupply vehicle, such as the Automated Transfer Vehicle (ATV) or Orbital Cygnus after it leaves the ISS and before it enters the atmosphere. A computer modelling effort will complement the experimental effort. Although the experiment will need to meet rigorous safety requirements to ensure the carrier vehicle does not sustain damage, the absence of a crew removes the need for strict containment of combustion products. This will facilitate the possibility of examining fire behaviour on a scale that is relevant to spacecraft fire safety and will provide unique data for fire model validation. This unprecedented opportunity will expand the understanding of the fundamentals of fire behaviour in spacecraft. The experiment is being developed by an international topical team that is collaboratively defining the experiment requirements and performing supporting analysis, experimentation and technology development. This paper presents the objectives, status and concept of this project.
Quality and safety aspects in histopathology laboratory
Adyanthaya, Soniya; Jose, Maji
2013-01-01
Histopathology is an art of analyzing and interpreting the shapes, sizes and architectural patterns of cells and tissues within a given specific clinical background and a science by which the image is placed in the context of knowledge of pathobiology, to arrive at an accurate diagnosis. To function effectively and safely, all the procedures and activities of histopathology laboratory should be evaluated and monitored accurately. In histopathology laboratory, the concept of quality control is applicable to pre-analytical, analytical and post-analytical activities. Ensuring safety of working personnel as well as environment is also highly important. Safety issues that may come up in a histopathology lab are primarily those related to potentially hazardous chemicals, biohazardous materials, accidents linked to the equipment and instrumentation employed and general risks from electrical and fire hazards. This article discusses quality management system which can ensure quality performance in histopathology laboratory. The hazards in pathology laboratories and practical safety measures aimed at controlling the dangers are also discussed with the objective of promoting safety consciousness and the practice of laboratory safety.

Yamaoka, Masaru; Yuyama, Yoshito; Nakamura, Masato; Oritate, Fumiko
In this study, we considered health and safety management for small-scale methane fermentation facilities that treat 2-5 ton of biomass daily based on several years operation experience with an approximate capacity of 5 t·d-1. We also took account of existing knowledge, related laws and regulations. There are no qualifications or licenses required for management and operation of small-scale methane fermentation facilities, even though rural sewerage facilities with a relative similar function are required to obtain a legitimate license. Therefore, there are wide variations in health and safety consciousness of the operators of small-scale methane fermentation facilities. The industrial safety and health laws are not applied to the operation of small-scale methane fermentation facilities. However, in order to safely operate a small-scale methane fermentation facility, the occupational safety and health management system that the law recommends should be applied. The aims of this paper are to clarify the risk factors in small-scale methane fermentation facilities and encourage planning, design and operation of facilities based on health and safety management.
Consumer food handling in the home: a review of food safety studies.
Redmond, Elizabeth C; Griffith, Christopher J
2003-01-01
Epidemiological data from Europe, North America, Australia, and New Zealand indicate that a substantial proportion of foodborne disease is attributable to improper food preparation practices in consumers' homes. International concern about consumer food safety has prompted considerable research to evaluate domestic food-handling practices. The majority of consumer food safety studies in the last decade have been conducted in the United Kingdom and Northern Ireland (48%) and in the United States (42%). Surveys (questionnaires and interviews), the most frequent means of data collection, were used in 75% of the reviewed studies. Focus groups and observational studies have also been used. One consumer food safety study examined the relationship between pathogenic microbial contamination from raw chicken and observed food-handling behaviors, and the results of this study indicated extensive Campylobacter cross-contamination during food preparation sessions. Limited information about consumers' attitudes and intentions with regard to safe food-handling behaviors has been obtained, although a substantial amount of information about consumer knowledge and self-reported practices is available. Observation studies suggest that substantial numbers of consumers frequently implement unsafe food-handling practices. Knowledge, attitudes, intentions, and self-reported practices did not correspond to observed behaviors, suggesting that observational studies provide a more realistic indication of the food hygiene actions actually used in domestic food preparation. An improvement in consumer food-handling behavior is likely to reduce the risk and incidence of foodborne disease. The need for the development and implementation of food safety education strategies to improve specific food safety behaviors is reviewed in this paper.

In this study, the authors evaluated college students' food safety attitudes, beliefs, knowledge, and self-reported practices and explored whether these variables were positively influenced by educational intervention. Students (n=59), were mostly seniors, health or non-health majors, and responsible for meal preparation. Subjects completed a food safety questionnaire (FSQ) prior to educational intervention, which consisted of three interactive modules. Subjects completed module pre-, post-, and post-posttests. The FSQ was also administered after exposure to intervention and five weeks later to determine changes in food safety attitudes, beliefs, knowledge, and self-reported practices. Students' FSQ attitude scores increased from 114 to 122 (p < or = .001); FSQ belief and knowledge scores improved from 86 to 98 (p < or = .001) and from 11 to 13 (p < or = .001), respectively. Food safety knowledge was also measured by module pre- and posttests, and improved significantly after intervention for all students, with health majors having the greatest increase. Intervention resulted in improved food safety self-reported practices for health majors only. The educational intervention appeared effective in improving food safety beliefs and knowledge. For health majors, attitudes and some self-reported practices improved. For all areas, the strongest effects were seen in health majors.

A child safety restraint (CSR) is an effective measure to reduce the risk of child injury from traffic collisions. This study aims to explore knowledge, attitudes, and behaviors regarding CSRs in a Chinese population. A cross-sectional survey regarding CSR use was conducted from April to May 2014 in Shenzhen municipality. Respondents were parents who had at least one child 0 to 6 years of age and owned a car. These parents provided a self-report of demographic characteristics as well as information about their knowledge, attitudes, and behaviors toward CSR use. Most respondents had a fair level of knowledge about CSRs, with higher mean knowledge scores demonstrated among the respondents who were male, had an advanced degree, had a higher income, owned an expensive car, had an older child, drove frequently with children, and routinely drove greater distances with children. In addition, most respondents had a more positive attitude toward CSR use, with a higher mean attitude score among those who had an advanced degree, owned an expensive car, drove frequently with children, and routinely drove greater distances with children. However, some myths regarding CSR use also existed (e.g., parents can effectively protect their children in a car collision by holding them, they are not required to purchase the CSR for child safety if there is no mandatory provision by law, among others). Among 3,768 respondents who had at least one child and a car, 27.8% (1,047) had a CSR and 22.9% (864) used the CSR. A logistic regression model showed the likelihood of CSR ownership to be higher if respondents drove frequently or greater distances and was dependent on both the education level of the respondents and the age of the children. The frequency of CSR use increased as the age of children decreased (P = .0274). Respondents who owned a CSR and those who frequently used CSRs had higher mean knowledge and mean attitude scores. This observational study found that although the majority of respondents had fair levels of knowledge and positive attitudes, they had lower rates of CSR ownership and use. Therefore, efforts at developing opportunities to expand public awareness of CSR use should be made to improve child passenger safety practices and eliminate child injury caused by traffic collisions.

In recent years, perception of flood risks has become an important topic to policy makers concerned with risk management and safety issues. Knowledge of the public risk perception is considered a crucial aspect in modern flood risk management as it steers the development of effective and efficient flood mitigation strategies. This study aimed at gaining insight into the perception of flood risks along the Belgian coast. Given the importance of the tourism industry on the Belgian coast, the survey considered both inhabitants and residential tourists. Based on actual expert's risk assessments, a high and a low risk area were selected for the study. Risk perception was assessed on the basis of scaled items regarding storm surges and coastal flood risks. In addition, various personal and residence characteristics were measured. Using multiple regression analysis, risk perception was found to be primarily influenced by actual flood risk estimates, age, gender, and experience with previous flood hazards. © 2011 Society for Risk Analysis.

Use of a pneumatic nail gun with a sequential actuation trigger (SAT) significantly diminishes the risk for acute traumatic injury compared to use of a contact actuation trigger (CAT) nail gun. A theoretically-based increased risk of work-related musculoskeletal disorders from use of a SAT nail gun, relative to CAT, appears unlikely and remains unproven. Based on current knowledge, the use of CAT nail guns cannot be justified as a safe alternative to SAT nail guns. This letter provides a perspective of ergonomists and occupational safety researchers recommending the use of the sequential actuation trigger for all nail gun tasks in the construction industry.
Family Violence and Family Physicians
Herbert, Carol P.

The acronym IDEALS summarizes family physicians' obligations when violence is suspected: to identify family violence; document injuries; educate families and ensure safety for victims; access resources and coordinate care; co-operate in the legal process; and provide support for families. Failure to respond reflects personal and professional experience and attitudes, fear of legal involvement, and lack of knowledge. Risks of intervention include physician burnout, physician overfunctioning, escalation of violence, and family disruption. PMID:21228987

Several factors have hindered effective use of information and resources related to food safety due to inconsistency among semantically heterogeneous data resources, lack of knowledge on profiling of food-borne pathogens, and knowledge gaps among research communities, government risk assessors/managers, and end-users of the information. This paper discusses technical aspects in the establishment of a comprehensive food safety information system consisting of the following steps: (a) computational collection and compiling publicly available information, including published pathogen genomic, proteomic, and metabolomic data; (b) development of ontology libraries on food-borne pathogens and design automatic algorithms with formal inference and fuzzy and probabilistic reasoning to address the consistency and accuracy of distributed information resources (e.g., PulseNet, FoodNet, OutbreakNet, PubMed, NCBI, EMBL, and other online genetic databases and information); (c) integration of collected pathogen profiling data, Foodrisk.org ( http://www.foodrisk.org ), PMP, Combase, and other relevant information into a user-friendly, searchable, "homogeneous" information system available to scientists in academia, the food industry, and government agencies; and (d) development of a computational model in semantic web for greater adaptability and robustness.

Antiretroviral drugs have well-documented evidence-based favorable benefit-risk ratios. Although various studies have investigated and characterized the safety profile of antiretroviral medicines, there are a limited number of studies evaluating the safety of first-line antiretroviral therapy (ART) in patients with a specific co-morbidity. A cohort event monitoring (CEM) study of the safety and effectiveness of antiretroviral medicines in a target population that has a significant level of co-morbidities (chronic infectious diseases, peripheral blood cytopenias) was implemented. The aim was to evaluate the safety profile of the highly active ART (HAART) in the target population and subpopulations with risk factors, to optimize the monitoring and decision-making procedure for subgroups of patients with specific types of co-morbidity, and to implement a more vigilant approach to therapy management in risk groups of patients. Prospective observational CEM was implemented among HAART-naïve HIV-positive patients at four clinical sites from December 2012. Eligible patients were those starting first-line HAART. Close medical supervision of all enrolled patients, with regular clinical and laboratory monitoring, was provided by healthcare professionals within 1 year after commencement of therapy. Standardized forms were used for data collection on initial and subsequent visits. All objective or subjective deviations in condition (events) were assessed for a causal relationship with ART, and for severity, seriousness, reversibility, preventability, and pre-existing risk factors in the case of adverse drug reactions (ADRs). A total of 518 HAART-naïve HIV-positive patients were enrolled in the CEM study. Of these patients, 65% (337) experienced one or several ADRs related to one or more components of HAART. Most of the ADRs reported were non-serious, expected, common (very common), transient (correctable), or reversible. The most common were hematotoxic, hepatotoxic, and neurotoxic adverse reactions. In several cases, some types of toxicities, associated with zidovudine, efavirenz, and nevirapine, had a high level of severity, necessitating hospitalization and drug regimen or single-agent substitution. Severe cases of hematological, hepatobiliary, and psychiatric toxicities were associated with pre-existing risk factors. CEM is an effective tool for safety and effectiveness monitoring and could be successfully implemented for intensive study of important safety issues and for overcoming knowledge gaps regarding safety. In order to achieve a favorable benefit-risk ratio for HAART in the specific sections of the population with pre-existing risk factors for development of ART toxicities, more vigilant consideration and careful assessment before therapy is commenced and further regular monitoring of key laboratory parameters is required.

Article-at-a-Glance Background Walkrounds, introduced as Leadership (or Executive) WalkRounds,™ are a widely advocated model for increasing leadership engagement in patient safety to improve safety culture, but evidence for their effectiveness is mixed. In the English National Health Service (NHS), hospitals have been strongly encouraged to make use of methods closely based on the walkrounds approach. A study was conducted to explore how walkrounds are used in practice and to identify variations in implementation that might mediate their impact on safety and culture. Methods The data, collected from 82 semistructured interviews in the English NHS, were drawn from two components of a wider study of culture and behavior around quality and safety in the English system. Analysis was based on the constant comparative method. Findings Our analysis highlights how local, pragmatic adjustments to the walkrounds approach could radically alter its character and the way in which it is received by those at the front line. The modification and expansion of walkrounds to increase the scope of knowledge produced could increase the value that executives draw from them. However, it risks replacing the main objectives of walkrounds—specific, actionable knowledge about safety issues, and a more positive safety culture and relationship between ward and board—with a form of surveillance that could alienate frontline staff and produce fallible insights. Conclusion The study’s findings suggest some plausible explanations for the mixed evidence for walkrounds’ effectiveness in creating a safety culture. On a practical level, they point to critical questions that executives must ask themselves in practicing interventions of this nature to ensure that adaptations align rather than conflict with the intervention’s model of change.

Evaluating North Carolina Food Pantry Food Safety-Related Operating Procedures.
Chaifetz, Ashley; Chapman, Benjamin
2015-11-01
Almost one in seven American households were food insecure in 2012, experiencing difficulty in providing enough food for all family members due to a lack of resources. Food pantries assist a food-insecure population through emergency food provision, but there is a paucity of information on the food safety-related operating procedures used in the pantries. Food pantries operate in a variable regulatory landscape; in some jurisdictions, they are treated equivalent to restaurants, while in others, they operate outside of inspection regimes. By using a mixed methods approach to catalog the standard operating procedures related to food in 105 food pantries from 12 North Carolina counties, we evaluated their potential impact on food safety. Data collected through interviews with pantry managers were supplemented with observed food safety practices scored against a modified version of the North Carolina Food Establishment Inspection Report. Pantries partnered with organized food bank networks were compared with those that operated independently. In this exploratory research, additional comparisons were examined for pantries in metropolitan areas versus nonmetropolitan areas and pantries with managers who had received food safety training versus managers who had not. The results provide a snapshot of how North Carolina food pantries operate and document risk mitigation strategies for foodborne illness for the vulnerable populations they serve. Data analysis reveals gaps in food safety knowledge and practice, indicating that pantries would benefit from more effective food safety training, especially focusing on formalizing risk management strategies. In addition, new tools, procedures, or policy interventions might improve information actualization by food pantry personnel.
Prior knowledge-based approach for associating ...
Evaluating the potential human health and/or ecological risks associated with exposures to complex chemical mixtures in the ambient environment is one of the central challenges of chemical safety assessment and environmental protection. There is a need for approaches that can help to integrate chemical monitoring and bio-effects data to evaluate risks associated with chemicals present in the environment. We used prior knowledge about chemical-gene interactions to develop a knowledge assembly model for detected chemicals at five locations near two wastewater treatment plants. The assembly model was used to generate hypotheses about the biological impacts of the chemicals at each location. The hypotheses were tested using empirical hepatic gene expression data from fathead minnows exposed for 12 d at each location. Empirical gene expression data was also mapped to the assembly models to statistically evaluate the likelihood of a chemical contributing to the observed biological responses. The prior knowledge approach was able reasonably hypothesize the biological impacts at one site but not the other. Chemicals most likely contributing to the observed biological responses were identified at each location. Despite limitations to the approach, knowledge assembly models have strong potential for associating chemical occurrence with potential biological effects and providing a foundation for hypothesis generation to guide research and/or monitoring efforts relat

Although there has been substantial research on the avoidance of risk, much less has been completed on voluntary risk. This study examined backcountry snowmobilers' risk perceptions, avalanche related information seeking behaviours, and decision-making processes when dealing with avalanches and backcountry risk in Canada. To accomplish this, in-depth, semi-structured interviews were conducted with 17 participants who were involved in backcountry snowmobiling. Interviews were done both in person and by telephone. The results of this study show that, unlike previous research on snowmobilers, the participants of this study were well prepared and knowledgeable about backcountry risks. All 17 participants stated that they carried a shovel, probe, and transceiver with them on each backcountry trip, and 10 participants had taken an avalanche safety course. Group dynamics and positive peer pressure were influential in promoting safe backcountry behaviour. KEYWORDS: Backcountry snowmobiling, Avalanches, Voluntary Risk, Preparedness, Decision-Making.
Evaluation of the food safety training for food handlers in restaurant operations
Park, Sung-Hee; Kwak, Tong-Kyung
2010-01-01
This study examined the extent of improvement of food safety knowledge and practices of employee through food safety training. Employee knowledge and practice for food safety were evaluated before and after the food safety training program. The training program and questionnaires for evaluating employee knowledge and practices concerning food safety, and a checklist for determining food safety performance of restaurants were developed. Data were analyzed using the SPSS program. Twelve restaurants participated in this study. We split them into two groups: the intervention group with training, and the control group without food safety training. Employee knowledge of the intervention group also showed a significant improvement in their score, increasing from 49.3 before the training to 66.6 after training. But in terms of employee practices and the sanitation performance, there were no significant increases after the training. From these results, we recommended that the more job-specific and hand-on training materials for restaurant employees should be developed and more continuous implementation of the food safety training and integration of employee appraisal program with the outcome of safety training were needed.

Research has shown that traditional food safety training programs and strategies to promote hand hygiene increases knowledge of the subject. However, very few studies have been conducted to evaluate the impact of food safety training on food handlers' attitudes about good hand hygiene practices. The objective of this meta-analytical study was to assess the extent to which food safety training or intervention strategies increased knowledge of and attitudes about hand hygiene. A systematic review of food safety training articles was conducted. Additional studies were identified from abstracts from food safety conferences and food science education conferences. Search terms included combinations of "food safety," "food hygiene," "training," "education," "hand washing," "hand hygiene," "knowledge," "attitudes," "practices," "behavior," and "food handlers." Only before- and after-training approaches and cohort studies with training (intervention group) and without training (control group) in hand hygiene knowledge and including attitudes in food handlers were evaluated. All pooled analyses were based on a random effects model. Meta-analysis values for nine food safety training and intervention studies on hand hygiene knowledge among food handlers were significantly higher than those of the control (without training), with an effect size (Hedges' g) of 1.284 (95% confidence interval [CI] ∼ 0.830 to 1.738). Meta-analysis of five food safety training and intervention studies in which hand hygiene attitudes and self-reported practices were monitored produced a summary effect size of 0.683 (95% CI ∼ 0.523 to 0.843). Food safety training increased knowledge and improved attitudes about hand hygiene practices. Refresher training and long-term reinforcement of good food handling behaviors may also be beneficial for sustaining good hand washing practices.

With the number of older adult arrestees and prisoners increasing rapidly, legal professionals increasingly provide front-line identification and response to age-related health conditions (including cognitive and physical impairments) that may affect legal outcomes, such as the ability to participate in one's defense or stay safe in jail. The goals of this study were to assess the ability of legal professionals to recognize and respond to age-related conditions that could affect legal outcomes and to identify recommendations to address important knowledge gaps. This was a mixed quantitative-qualitative study. Legal professionals (N = 72) in the criminal justice system were surveyed to describe their demographic characteristics, expertise, and prior aging-related training and to inform the qualitative interview guide. Those surveyed included attorneys (district attorneys (25%), public defenders and legal advocates (58%)), judges (6%), and court-affiliated social workers (11%). In-depth qualitative interviews were then conducted with a subset of 10 legal professionals who worked with older adults at least weekly. Results from the surveys and interviews revealed knowledge deficits in four important areas: age-related health, identification of cognitive impairment, assessment of safety risk, and optimization of services upon release from jail. Four recommendations to close these gaps emerged: educate legal professionals about age-related health, train professionals to identify cognitive and sensory impairment, develop checklists to identify those at risk of poor health or safety, and improve knowledge of and access to transitional services for older adults. These findings suggest that geriatrics knowledge gaps of legal professionals exist that may contribute to adverse medical or legal outcomes for older adults involved in the criminal justice system and that partnerships between healthcare and legal professionals are needed to address these challenges. © Published 2014.

Occupational health policies on risk assessment in Japan.
Horie, Seichi
2010-09-01
Industrial Safety and Health Law (ISH Law) of Japan requires abnormalities identified in evaluations of worker health and working environments are reported to occupational physicians, and employers are advised of measures to ensure appropriate accommodations in working environments and work procedures. Since the 1980s, notions of a risk assessment and occupational safety and health management system were expected to further prevent industrial accidents. In 2005, ISH Law stipulated workplace risk assessment using the wording "employers shall endeavor." Following the amendment, multiple documents and guidelines for risk assessment for different work procedures were developed. They require ISH Laws to be implemented fully and workplaces to plan and execute measures to reduce risks, ranking them from those addressing potential hazards to those requiring workers to wear protective articles. A governmental survey in 2005 found the performance of risk assessment was 20.4% and common reasons for not implementing risk assessments were lack of adequate personnel or knowledge. ISH Law specifies criminal penalties for both individuals and organizations. Moreover, under the Labor Contract Law promulgated in 2007, employers are obliged to make reasonable efforts to ensure employee health for foreseeable and avoidable risks. Therefore, enterprises neglecting even the non-binding provisions of guidelines are likely to suffer significant business impact if judged to be responsible for industrial accidents or occupational disease. To promote risk assessment, we must strengthen technical, financial, and physical support from public-service organizations, encourage the dissemination of good practices to reduce risks, and consider additional employer incentives, including relaxed mandatory regulations.
[Knowledge of students of tourism and recreation Academy of Physical Education on wild mushrooms].

2011-01-01
Prophylaxis of acute poisoning with mushrooms is justified because of the relatively high risk of death associated with these intoxications. Mushrooming in Poland has a long tradition and knowledge about mushrooms is usually passed on in families. In recent years the mushrooming becomes an organized form of recreation. Graduates of tourism and recreation should have a minimum of reliable knowledge about mushrooms, to ensure the safety of persons entrusted to their care. The knowledge of wild mushrooms among students of tourism and recreation was tested by means of questionnaire. Mushrooms gathered 108 out of 125 respondents. The primary source of knowledge about mushrooms for 84% of the mushrooms pickers were the parents. Up to 70% of respondents considered at least one of irrational methods useful to distinguish edible mushrooms from the poisonous. Thirteen percent of those polled believed that by simple means mushrooms may be deprived of their toxic properties. Knowledge of the only one deadly poisonous mushrooms growing in Poland was 53%. The tourism and recreation students must pass basic knowledge about mushrooms and identify reliable sources of knowledge in this field.

Schools have a fundamental role in broadening the understanding of natural hazard and risks and in building the awareness in the community. Recent earthquakes in Italy and worldwide, have clearly demonstrated that the poor perception of seismic hazards diminishes the effectiveness of mitigation countermeasures. Since years the Seismology's department of OGS is involved in education projects and public activities to raise awareness about earthquakes. Working together with teachers we aim at developing age-appropriate curricula to improve the student's knowledge about earthquakes, seismic safety, and seismic risk reduction. Some examples of education activities we performed during the last years are here presented. We show our experience with the primary and intermediate schools where, through hands-on activities, we explain the earthquake phenomenon and its effects to kids, but we illustrate also some teaching interventions for high school students. During the past years we lectured classes, we led laboratory and field activities, and we organized summer stages for selected students. In the current year we are leading a project aimed at training high school students on seismic safety through a multidisciplinary approach that involves seismologists, engineers and experts of safety procedures. To combine the objective of dissemination of earthquake culture, also through the knowledge of the past seismicity, with that of a safety culture, we use innovative educational techniques and multimedia resources. Students and teachers, under the guidance of an expert seismologist, organize a combination of hands-on activities for understanding earthquakes in the lab through cheap tools and instrumentations At selected schools we provided the low cost seismometers of the QuakeCatcher network (http://qcn.stanford.edu) for recording earthquakes, and we trained teachers to use such instruments in the lab and to analyze recorded data. Within the same project we are going to train selected students as communicators so that they can transfer simple educational messages on the seismic risk reduction to other students and/or to the whole community. The experiment is taking place in North East Italy, an area on which OGS detect earthquakes for seismological study and seismic alarm purposes. Teachers and students participating in the project are expected to present their achieved experience during a public event, at University of Udine (Italy).

The aim of this study was to assess pregnant women's Internet searching activity about medication safety, knowledge and perceptions of medication risk and willingness to take prescribed and non-prescribed medication or make online medication purchases. Online medication advice for pregnant women is complex. The quality and veracity of this data is increasingly important as more midwives report women are bringing retrieved online information to clinical appointments. Pregnant women's use of the Internet for seeking medication advice and purchasing medications has not yet been fully investigated. Online survey conducted from January - March 2013. Of the 284 respondents, 39% were taking a medication when they became pregnant and 76% had searched the Internet for medication safety information. Analgesics were the most commonly searched category (41%). Health service sites were the most common online source and regarded as the most helpful and trusted. Regardless of age and education level, 90% of women agreed that if trying to become pregnant they would reconsider taking any medications because of the potential risk to their unborn baby. Forty-six percent of women with higher levels of education consider buying medication online as safe, a greater proportion than those of lower education. Five percent of women reported buying medication online. The lack of specific recommendations for medication use during pregnancy is challenging for healthcare staff and pregnant women who need robust evidence to make informed treatment decisions. The Internet is a recognized, commonly accessed, source of medication information for pregnant women. © 2017 John Wiley & Sons Ltd.

Efforts are underway to transform regulatory toxicology and chemical safety assessment from a largely empirical science based on direct observation of apical toxicity outcomes in whole organism toxicity tests to a predictive one in which outcomes and risk are inferred from accumulated mechanistic understanding. The adverse outcome pathway (AOP) framework provides a systematic approach for organizing knowledge that may support such inference. Likewise, computational models of biological systems at various scales provide another means and platform to integrate current biological understanding to facilitate inference and extrapolation. We argue that the systematic organization of knowledge into AOP frameworks can inform and help direct the design and development of computational prediction models that can further enhance the utility of mechanistic and in silico data for chemical safety assessment. This concept was explored as part of a workshop on AOP-Informed Predictive Modeling Approaches for Regulatory Toxicology held September 24–25, 2015. Examples of AOP-informed model development and its application to the assessment of chemicals for skin sensitization and multiple modes of endocrine disruption are provided. The role of problem formulation, not only as a critical phase of risk assessment, but also as guide for both AOP and complementary model development is described. Finally, a proposal for actively engaging the modeling community in AOP-informed computational model development is made. The contents serve as a vision for how AOPs can be leveraged to facilitate development of computational prediction models needed to support the next generation of chemical safety assessment.

Transportation professionals are sometimes required to make difficult transportation safety investment decisions in the face of uncertainty. In particular, an engineer may be expected to choose among an array of technologies and/or countermeasures to remediate perceived safety problems when: (1) little information is known about the countermeasure effects on safety; (2) information is known but from different regions, states, or countries where a direct generalization may not be appropriate; (3) where the technologies and/or countermeasures are relatively untested, or (4) where costs prohibit the full and careful testing of each of the candidate countermeasures via before-after studies. The importance of an informed and well-considered decision based on the best possible engineering knowledge and information is imperative due to the potential impact on the numbers of human injuries and deaths that may result from these investments. This paper describes the formalization and application of a methodology to evaluate the safety benefit of countermeasures in the face of uncertainty. To illustrate the methodology, 18 countermeasures for improving safety of at grade railroad crossings (AGRXs) in the Republic of Korea are considered. Akin to "stated preference" methods in travel survey research, the methodology applies random selection and laws of large numbers to derive accident modification factor (AMF) densities from expert opinions. In a full Bayesian analysis framework, the collective opinions in the form of AMF densities (data likelihood) are combined with prior knowledge (AMF density priors) for the 18 countermeasures to obtain 'best' estimates of AMFs (AMF posterior credible intervals). The countermeasures are then compared and recommended based on the largest safety returns with minimum risk (uncertainty). To the author's knowledge the complete methodology is new and has not previously been applied or reported in the literature. The results demonstrate that the methodology is able to discern anticipated safety benefit differences across candidate countermeasures. For the 18 at grade railroad crossings considered in this analysis, it was found that the top three performing countermeasures for reducing crashes are in-vehicle warning systems, obstacle detection systems, and constant warning time systems.

When software safety requirements are imposed on legacy safety-critical systems, retrospective safety cases need to be formulated as part of recertifying the systems for further use and risks must be documented and managed to give confidence for reusing the systems. The SEJ Software Development Risk Taxonomy [4] focuses on general software development issues. It does not, however, cover all the safety risks. The Software Safety Risk Taxonomy [8] was developed which provides a construct for eliciting and categorizing software safety risks in a straightforward manner. In this paper, we present extended work on the taxonomy for safety that incorporates the additional issues inherent in the development and maintenance of safety-critical systems with software. An instrument called a Software Safety Risk Taxonomy Based Questionnaire (TBQ) is generated containing questions addressing each safety attribute in the Software Safety Risk Taxonomy. Software safety risks are surfaced using the new TBQ and then analyzed. In this paper we give the definitions for the specialized Product Engineering Class within the Software Safety Risk Taxonomy. At the end of the paper, we present the tool known as the 'Legacy Systems Risk Database Tool' that is used to collect and analyze the data required to show traceability to a particular safety standard

A recognised research-to-practice gap exists in the health research field of sports injury prevention and safety promotion. There is a need for improved insight into increasing the relevancy, accessibility and legitimacy of injury prevention and safety promotion research knowledge for sport settings. The role of key organisations as intermediaries in the process of health knowledge translation for sports settings remains under-explored, and this paper aims to determine, and describe, the processes of knowledge translation undertaken by a set of key organisations in developing and distributing injury prevention and safety promotion resources. The National Guidance for Australian Football Partnerships and Safety (NoGAPS) project provided the context for this study. Representatives from five key NoGAPS organisations participated in individual face-to-face interviews about organisational processes of knowledge translation. A qualitative descriptive methodology was used to analyse participants' descriptions of knowledge translation activities undertaken at their respective organisations. Several themes emerged around health knowledge translation processes and considerations, including (1) identifying a need for knowledge translation, (2) developing and disseminating resources, and (3) barriers and enablers to knowledge translation. This study provides insight into the processes that key organisations employ when developing and disseminating injury prevention and safety promotion resources within sport settings. The relevancy, accessibility and legitimacy of health research knowledge is foregrounded, with a view to increasing the influence of research on the development of health-related resources suitable for community sport settings.

The purpose of this article is to present the contribution of a trans-disciplinary approach focused on ergonomics and chemical risk control. We shall more precisely discuss how such an approach carried out in the field of agricultural work has made it possible to highlight serious shortcomings in the effectiveness of the coveralls that are supposed to protect vineyard workers from pesticides. The study results, as well as the whistle-blow that followed have questioned the control and prevention measures used until then. The aforementioned trans-disciplinary approach gathers knowledge and methods from epidemiology, industrial hygiene, occupational health and safety and ergonomics. Ergonomics were central in the development of the approach as it connected task and activity analysis with contamination measurements. Lastly, the first results that were obtained have been confirmed and reused by the AFSSET (Agence Française de Sécurité Sanitaire Environnement et Travail, the French governmental agency in charge of environmental health and occupational health and safety issues) regarding the agricultural sector but also for all other situations in which workers use coveralls as protection against chemical risks.

The field of stem cell therapeutics is moving ever closer to widespread application in the clinic. However, despite the undoubted potential held by these therapies, the balance between risk and benefit remains difficult to predict. As in any new field, a lack of previous application in man and gaps in the underlying science mean that regulators and investigators continue to look for a balance between minimizing potential risk and ensuring therapies are not needlessly kept from patients. Here, we attempt to identify the important safety issues, assessing the current advances in scientific knowledge and how they may translate to clinical therapeutic strategies in the identification and management of these risks. We also investigate the tools and techniques currently available to researchers during preclinical and clinical development of stem cell products, their utility and limitations, and how these tools may be strategically used in the development of these therapies. We conclude that ensuring safety through cutting-edge science and robust assays, coupled with regular and open discussions between regulators and academic/industrial investigators, is likely to prove the most fruitful route to ensuring the safest possible development of new products.

Production of sufficient, safe and nutritious food is a global challenge faced by the actors operating in the food production chain. The performance of food-producing systems from farm to fork is directly and indirectly influenced by major changes in, for example, climate, demographics, and the economy. Many of these major trends will also drive the development of food safety risks and thus will have an effect on human health, local societies and economies. It is advocated that a holistic or system approach taking into account the influence of multiple "drivers" on food safety is followed to predict the increased likelihood of occurrence of safety incidents so as to be better prepared to prevent, mitigate and manage associated risks. The value of using a Bayesian Network (BN) modelling approach for this purpose is demonstrated in this paper using food fraud as an example. Possible links between food fraud cases retrieved from the RASFF (EU) and EMA (USA) databases and features of these cases provided by both the records themselves and additional data obtained from other sources are demonstrated. The BN model was developed from 1393 food fraud cases and 15 different data sources. With this model applied to these collected data on food fraud cases, the product categories that thus showed the highest probabilities of being fraudulent were "fish and seafood" (20.6%), "meat" (13.4%) and "fruits and vegetables" (10.4%). Features of the country of origin appeared to be important factors in identifying the possible hazards associated with a product. The model had a predictive accuracy of 91.5% for the fraud type and demonstrates how expert knowledge and data can be combined within a model to assist risk managers to better understand the factors and their interrelationships.

Introduction Pulmonary nodules are detected in over a million Americans each year. Prior qualitative work suggests the detection of incidental pulmonary nodules can be burdensome for patients, but it is unknown whether these findings generalize to a broader sample of patients. We categorized patients’ knowledge, beliefs, and distress associated with detection and evaluation of a pulmonary nodule, and their impressions of clinician communication. Methods We administered a cross-sectional survey to adults with an incidental pulmonary nodule recruited from a rural medical center, an urban safety net hospital, and a Veterans Affairs hospital. Results Of 490 surveys mailed, 244 (50%) responded. Median nodule size was 7 mm; mean patient age was 67 years; 29% were female, and 86% were white. A quarter (26%) of respondents reported clinically significant distress related to their nodule as measured by the Impact of Event scale, our primary outcome. Patients reported multiple concerns including uncertainty about the nodule’s etiology (78%), the possibility of cancer (73%), and the possible need for surgery (64%). Only 25% of patients accurately estimated their lung cancer risk (within 15% of their actual risk); overall there was no correlation between perceived and actual risk (r=−0.007, p=0.93). Among the 23% of patients who did receive cancer risk information from their provider, they were more likely to find this information reassuring (16%) than scary (7%). Conclusion A quarter of patients with incidental pulmonary nodules experienced clinically significant distress. Knowledge about cancer risk and evaluation was poor. Clinician communication may help bridge knowledge gaps and alleviate distress in some patients. PMID:26961390

TeamSTEPPS for health care risk managers: Improving teamwork and communication.
Cooke, Marcia
2016-07-01
Ineffective communication among the health care team is a leading cause of errors in the patient care setting. Studies assessing training related to communication and teamwork in the clinical team are prevalent, however, teamwork training at the administrative level is lacking. This includes individuals in leadership positions such as health care risk managers. The purpose was to determine the impact of an educational intervention on the knowledge and attitudes related to communication and teamwork in the health care risk management population. The educational intervention was an adaptation of a national teamwork training program and incorporated didactic content as well as video vignettes and small group activities. Measurement of knowledge and attitudes were used to determine the impact of the education program. Knowledge and attitudes were assessed pre- and postcourse. Findings indicate that teamwork education tailored to the needs of the specific audience resulted in knowledge gained and improved attitudes toward the components of teamwork. The attitudes that most significantly improved were related to team structure and situation monitoring. There was no improvement in participants' attitudes toward leadership, mutual support, and communication. Team training has been shown to improve safety culture, patient satisfaction, and clinical outcomes. Including risk managers in training on teamwork, communication, and collaboration can serve to foster a common language among clinicians and management. In addition, a measurement related to implementation in the health care setting may yield insight into the impact of training. Qualitative measurement may allow the researcher to delve deeper into how these health care facilities are using team training interventions. © 2016 American Society for Healthcare Risk Management of the American Hospital Association.
Maritime Transportation Risk Assessment of Tianjin Port with Bayesian Belief Networks.

2016-06-01
This article develops a Bayesian belief network model for the prediction of accident consequences in the Tianjin port. The study starts with a statistical analysis of historical accident data of six years from 2008 to 2013. Then a Bayesian belief network is constructed to express the dependencies between the indicator variables and accident consequences. The statistics and expert knowledge are synthesized in the Bayesian belief network model to obtain the probability distribution of the consequences. By a sensitivity analysis, several indicator variables that have influence on the consequences are identified, including navigational area, ship type and time of the day. The results indicate that the consequences are most sensitive to the position where the accidents occurred, followed by time of day and ship length. The results also reflect that the navigational risk of the Tianjin port is at the acceptable level, despite that there is more room of improvement. These results can be used by the Maritime Safety Administration to take effective measures to enhance maritime safety in the Tianjin port. © 2016 Society for Risk Analysis.
Nanomedicine and epigenome. Possible health risks.
Smolkova, Bozena; Dusinska, Maria; Gabelova, Alena
2017-11-01
Nanomedicine is an emerging field that combines knowledge of nanotechnology and material science with pharmaceutical and biomedical sciences, aiming to develop nanodrugs with increased efficacy and safety. Compared to conventional therapeutics, nanodrugs manifest higher stability and circulation time, reduced toxicity and improved targeted delivery. Despite the obvious benefit, the accumulation of imaging agents and nanocarriers in the body following their therapeutic or diagnostic application generates concerns about their safety for human health. Numerous toxicology studies have demonstrated that exposure to nanomaterials (NMs) might pose serious risks to humans. Epigenetic modifications, representing a non-genotoxic mechanism of toxicant-induced health effects, are becoming recognized as playing a potential causative role in the aetiology of many diseases including cancer. This review i) provides an overview of recent advances in medical applications of NMs and ii) summarizes current evidence on their possible epigenetic toxicity. To discern potential health risks of NMs, since current data are mostly based upon in vitro and animal models, a better understanding of functional relationships between NM exposure, epigenetic deregulation and phenotype is required.

Complex systems are comprised of technical, social, political and environmental factors as well as the programmatic factors of cost, schedule and risk. Testing these systems for enhanced security requires expert knowledge in many different fields. It is important to test these systems to ensure effectiveness, but testing is limited to due cost, schedule, safety, feasibility and a myriad of other reasons. Without an effective decision framework for Test and Evaluation (T&E) planning that can take into consideration technical as well as programmatic factors and leverage expert knowledge, security in complex systems may not be assessed effectively. Therefore, this paper coversmore » the identification of the current T&E planning problem and an approach to include the full variety of factors and leverage expert knowledge in T&E planning through the use of Bayesian Networks (BN).« less

To develop an understanding of factors acting as barriers and motivators to parental uptake of child poison safety strategies. A qualitative study involving semistructured interviews and focus groups. A grounded theory approach was used for the collection and analysis of data. Sixty five parents of children under 5 years of age, some of whom had experienced an unintentional child poisoning incident. A range of knowledge based, environmental, and behavioral barriers to comprehensive parental uptake of poison safety practices were identified. As a result there tended to be only partial implementation of safety initiatives in the home. Selection of safety practices was often guided by the interests and behaviors of the child. This made the child vulnerable to changes in the home environment, inadequate supervision, and/or shifts in their own behavior and developmental ability. Personal or vicarious exposure of a parent to a child poisoning incident was a significant motivator for parental review of safety practices. Environmental measures targeting child resistant containers, warning labels, and lockable poisons cupboards will support parents' efforts to maintain poison safety. Additional education campaigns using stories of actual poisoning incidents may help to increase awareness of risk and encourage increased uptake.

Pedestrian injuries contribute greatly to child morbidity and mortality. Recent evidence suggests that training within virtual pedestrian environments may improve children’s street crossing skills, but may not convey knowledge about safety in street environments. We hypothesized that (a) children will gain pedestrian safety knowledge via videos/software/internet websites, but not when trained by virtual pedestrian environment or other strategies; (b) pedestrian safety knowledge will be associated with safe pedestrian behavior both before and after training; and (c) increases in knowledge will be associated with increases in safe behavior among children trained individually at streetside locations, but not those trained by means of other strategies. We analyzed data from a randomized controlled trial evaluating pedestrian safety training. We randomly assigned 240 children ages 7–8 to one of four training conditions: videos/software/internet, virtual reality (VR), individualized streetside instruction, or a no-contact control. Both virtual and field simulations of street crossing at 2-lane bi-directional mid-block locations assessed pedestrian behavior at baseline, post-training, and 6-month follow-up. Pedestrian knowledge was assessed orally on all three occasions. Children trained by videos/software/internet, and those trained individually, showed increased knowledge following training relative to children in the other groups (ps < 0.01). Correlations between pedestrian safety knowledge and pedestrian behavior were mostly non-significant. Correlations between change in knowledge and change in behavior from pre- to post-intervention also were non-significant, both for the full sample and within conditions. Children trained using videos/software/internet gained knowledge but did not change their behavior. Children trained individually gained in both knowledge and safer behavior. Children trained virtually gained in safer behavior but not knowledge. If VR is used for training, tools like videos/internet might effectively supplement training. We discovered few associations between knowledge and behavior, and none between changes in knowledge and behavior. Pedestrian safety knowledge and safe pedestrian behavior may be orthogonal constructs that should be considered independently for research and training purposes. PMID:24573688

Female sex workers (FSWs) are an important population for HIV acquisition and transmission. Their risks are shaped by behavioral, sexual network, and structural level factors. Violence is pervasive and associated with HIV risk behavior and infection, yet interventions to address the dual epidemics of violence and HIV among FSWs are limited. We used participatory methods to develop a brief, trauma-informed intervention, INSPIRE (Integrating Safety Promotion with HIV Risk Reduction), to improve safety and reduce HIV risk for FSWs. A quasi-experimental, single group pretest-posttest study evaluated intervention feasibility, acceptability and efficacy among FSWs in Baltimore, MD, most of whom were drug-involved (baseline n = 60; follow-up n = 39 [65%]; non-differential by demographics or outcomes). Qualitative data collected at follow-up contextualizes findings. Based on community partnership and FSW input, emergent goals included violence-related support, connection with services, and buffering against structural forces that blame FSWs for violence. Qualitative and quantitative results demonstrate feasibility and acceptability. At follow-up, improvements were seen in avoidance of client condom negotiation (p = 0.04), and frequency of sex trade under the influence of drugs or alcohol (p = 0.04). Women's safety behavior increased (p < 0.001). Participants improved knowledge and use of sexual violence support (p < 0.01) and use of intimate partner violence support (p < 0.01). By follow-up, most respondents (68.4%) knew at least one program to obtain assistance reporting violence to police. Over the short follow-up period, client violence increased. In reflecting on intervention acceptability, participants emphasized the value of a safe and supportive space to discuss violence. This brief, trauma-informed intervention was feasible and highly acceptable to FSWs. It prompted safety behavior, mitigated sex trade under the influence, and bolstered confidence in condom negotiation. INSPIRE influenced endpoints deemed valuable by community partners, specifically improving connection to support services and building confidence in the face of myths that falsely blame sex workers for violence. Violence persisted; prevention also requires targeting perpetrators, and longer follow-up durations as women acquire safety skills. This pilot study informs scalable interventions that address trauma and its impact on HIV acquisition and care trajectories for FSWs. Addressing violence in the context of HIV prevention is feasible, acceptable to FSWs, and can improve safety and reduce HIV risk, thus supporting FSW health and human rights.

Promoting resilience among displaced adolescent girls in northern Pakistan may buffer against developmental risks such as violence exposure and associated longer-term consequences for physical and mental well-being. However, girls' access to such programming may be limited by social norms restricting movement. A mixed-method evaluation examined change over time, feasibility, and acceptability of the COMPASS program in three districts of Khyber-Pakhtunkhwa province through a single-group within-participant pretest-posttest of adolescent girls aged 12-19 enrolled in the intervention (n = 78), and qualitative in-depth interviews with girls following posttest completion (n = 15). Primary outcomes included improvements in movement, safety, and comfort discussing life skills topics with caregivers, operationalized quantitatively as number of places visited in the previous month, number of spaces that girls felt safe visiting, and comfort discussing puberty, education, working outside the home, and marriage, respectively. Secondary outcomes included psychosocial well-being, gendered rites of passage, social support networks, perceptions of support for survivors of violence, and knowledge of services. Quantitative pretest-posttest findings included significant improvements in movement, psychosocial well-being, and some improvements in social support, knowledge of services, and gendered rites of passage; findings on safety and comfort discussing life skills topics were not significant. Qualitative findings illuminated themes related to definitions of safety and freedom of movement, perceptions and acceptability of program content, perceptions of social support, and perceptions of blame and support and knowledge of services in response to violence. Taken together, findings illustrate positive impacts of life skills programming, and the need for societal changes on gender norms to improve girls' safety in public spaces and access to resources.

Sun protection is a major concern for outdoor workers as they are particularly exposed to solar ultraviolet radiation and therefore at increased risk of developing some forms of skin cancer, cataract and ocular neoplasm. In order to provide an overview of outdoor workers' sun-related knowledge, attitudes and protective behaviours as reported in the literature and to evaluate the effectiveness of sun-safety education programmes in outdoor occupational settings, we conducted a systematic review of the literature by searching three electronic databases (PubMed, Embase, PsycINFO) from their inception up to 25 April 2012. An extensive hand search complemented the database searches. We identified 34 relevant articles on descriptive studies and 18 articles on interventional studies. Considerable numbers of outdoor workers were found to have sun-sensitive skin types; sunburn rates per season ranged from 50% to 80%. Data concerning outdoor workers' sun-related knowledge and attitudes were scarce and controversial. The reported sun-protective behaviours were largely inadequate, with many workers stating that they never or only rarely wore a long-sleeved shirt (50-80%), sun-protective headgear (30-80%) and sunscreen (30-100%) while working in the sun. However, there is growing evidence that occupational sun-safety education is effective in increasing outdoor workers' sun-protection habits and presumably in decreasing sunburn rates. Occupational sun-safety education programmes offer great potential for improving outdoor workers' largely insufficient sun-protective behaviours. It is hoped that, in the future, committed support from healthcare authorities, cancer foundations, employers and dermatologists will open the way for rapid and uncomplicated implementation of sun-safety education programmes. © 2012 The Authors.

We conducted a qualitative study of male sex work in St. Petersburg Russia with a focus on social vulnerabilities, HIV-risk perception and HIV-related behaviours. In-depth interviews were conducted with individuals knowledgeable about male sex work through their profession and with male sex workers themselves. Male sex work involves a variety of exchanges, including expensive vacations, negotiated monetary amounts or simply access to food. Methods of finding clients included the Internet, social venues (e.g. gay clubs and bars) and public places (e.g. parks). Use of the Internet greatly facilitated male sex work in a variety of ways. It was used by both individuals and agencies to find clients, and appeared to be increasing. Men often reported not being professionally connected to other male sex workers and limited disclosure about their work. Many were aware of the work-related risks to personal safety, including violence and robbery by clients. Perceived risk for HIV was mostly abstract and several exceptions to condom use with clients were noted. Alcohol use was reported as moderate but alcohol was consumed frequently in association with work. These data suggest that the most salient risks for male sex workers include professional isolation, threats to personal safety, limited perceived HIV risk and sub-optimal levels of condom use.

Outcome measures for safety training effectiveness research often do not include measures such as occupational injury experience. Effectiveness mediators also receive sparse attention. A new safety training curriculum was delivered to workers in a stratified random sample of food service facilities across three companies. A similar group of facilities received usual training. We collected post-test measures of demographic variables, safety knowledge, perceptions of transfer of training climate, and workers' compensation claim data for one year after the initial training activities. Knowledge test scores were apparently higher in the new-training units than in the usual-training units. Some demographic variables were inconsistently associated with these differences. Evidence for reduction of the injury rate associated with the new training was observed from two companies but only approached significance for one company. A second company revealed a similar but non-significant trend. Knowledge scores were not significantly associated with lower injury rates. We found evidence that safety training increases knowledge and reduces injuries. We found almost no evidence of effects of training effectiveness mediators, including no relationship between safety knowledge and injury experience. Methodological issues related to conducting a large study may have influenced these results. Although safety training leads to greater knowledge and, in some cases, reduced occupational injuries, the influence of mediating variables remains to be fully explained.

2004-07-01
As a new risk communication method for the construction of effective knowledge bases about 'safety and non-anxiety for nuclear energy', a study on new communication method of social risk information by means of electronic communication has been started, by noticing rapid expansion of internet usage in the society. The purpose of this research is to enhance the public acceptance to nuclear power in Japan by the following two aspects. The first is to develop the mutual communication system among the working persons involved in both the operation and maintenance activities for nuclear power plant, by which they will exchange theirmore » daily experiences to improve the safety conscious activities to foster 'safety culture' attitude. The other is the development of an effective risk communication system between nuclear society and the general publics about the hot issues of 'what are the concerned involved in the final disposal of high-level radioactive waste?' and 'what should we do to have social consensus to deal with this issue in future'. The authors' research plan for the above purpose is summarized as shown in Table 1. As the first step of the authors' three year research project which started from August 2003, social investigation by questionnaires by internet and postal mail, have been just recently conducted on their risk perception for the nuclear power for the people engaged in nuclear business and women in the metropolitan area, respectively, in order to obtain the relevant information on how and what should be considered for constructing effective risk communication methods of social risk information between the people within nuclear industries and the general public in society. Although there need to be discussed, the contrasting risk images as shown in Fig.1, can be depicted between the nuclear people and general public these days in Japan, from the results of the social investigation. As the conclusion of the authors' study thus far conducted, the contrasting risk perceptions by both the nuclear people and the general public which are shown in Fig. 1, will contribute to the authors' development of two risk communication systems as the next step of this research project, the one for 'Community network system to foster safety culture among nuclear workers', while the other for 'Affective risk communication network open to society'.

Communication of medical product risk: how effective is effective enough?
Goldman, Stephen A
2004-01-01
Ever-increasing attention is being paid worldwide to the safety of medical products, and the risks associated with their use. The integral role of risk communication in overall risk management is demonstrated by several recent market withdrawals of drugs, in which a perceived incapability of healthcare systems to manage well-characterised, avoidable risks was a significant factor. With advances in clinical pharmacology, pharmacogenomics and pharmacoepidemiology expanding our knowledge of medical products, effective delivery of the latest safety-related information to health professionals and consumers becomes even more imperative. In this regard, it is important to evaluate whether current modes of risk communication lead to desired changes in relevant behaviours such as prescribing or drug monitoring, particularly in context with which achieved level of effectiveness is deemed acceptable. This is crucial, as there have been product-specific risk communication efforts that achieved a fair degree of success, yet were not seen as effective enough to prevent market withdrawal of the medical product in question. In the service of improving public health through enhanced risk communication, it is essential to critically assess current methods, both as to results achieved (or not), and whether each method is applicable to the various types of risks associated with medical product use. Furthermore, just as combining methods may well improve overall risk communication, there are societal and psychological factors that must be considered in attempting to maximise effectiveness. However, in assessing risk communication effectiveness, the particular benefit- risk relationship of any individual medical product must also be part of the evaluative process.
Managing uncertainty about food risks - Consumer use of food labelling.
Tonkin, Emma; Coveney, John; Meyer, Samantha B; Wilson, Annabelle M; Webb, Trevor
2016-12-01
General consumer knowledge of and engagement with the production of food has declined resulting in increasing consumer uncertainty about, and sensitivity to, food risks. Emphasis is therefore placed on providing information for consumers to reduce information asymmetry regarding food risks, particularly through food labelling. This study examines the role of food labelling in influencing consumer perceptions of food risks. In-depth, 1-h interviews were conducted with 24 Australian consumers. Participants were recruited based on an a priori defined food safety risk scale, and to achieve a diversity of demographic characteristics. The methodological approach used, adaptive theory, was chosen to enable a constant interweaving of theoretical understandings and empirical data throughout the study. Participants discussed perceiving both traditional (food spoilage/microbial contamination) and modern (social issues, pesticide and 'chemical' contamination) risks as present in the food system. Food labelling was a symbol of the food system having managed traditional risks, and a tool for consumers to personally manage perceived modern risks. However, labelling also raised awareness of modern risks not previously considered. The consumer framing of risk presented demonstrates the need for more meaningful consumer engagement in policy decision making to ensure risk communication and management meet public expectations. This research innovatively identifies food labelling as both a symbol of, and a tool for, the management of perceived risks for consumers. Therefore it is imperative that food system actors ensure the authenticity and trustworthiness of all aspects of food labelling, not only those related to food safety. Copyright © 2016 Elsevier Ltd.

Identification of perceptions about herpes zoster (HZ) disease, vaccine effectiveness and safety, and vaccine recommendations may impact immunization practices of physicians for HIV-infected patients. A survey was used to quantify knowledge of HZ as well as determine physician immunization perceptions and practices. There were 272/1700 respondents (16%). Correct answers for the incidence of varicella zoster virus (VZV) infection in adults and incidence of HZ in HIV-infected patients were recorded by 14% and 10% of providers, respectively. Providers reported poor knowledge of the incidence of disease recurrence in HIV-infected patients (41% correct), potency of HZ vaccine (47.5% correct) and mechanism of protection against reactivation of VZV (66% correct). Most (88%) agreed that HZ was a serious disease, and 73% believed that the burden of disease made vaccination important. A majority (75%) did not vaccinate HIV patients with HZ vaccine regardless of antiretroviral therapy status. Barriers to administration included safety concerns, concern that vaccine would not prevent HZ, risk of HZ dissemination, reimbursement issues and lack of Infectious Diseases Society of America (IDSA) guidelines. Only 38% of providers agreed that CDC guidelines were clear and 50% believed that clinical trials were needed prior to use of HZ vaccine in HIV-infected patients. Education about HZ is needed among HIV providers. Providers perceived vaccination as important, but data on vaccine safety and clear guidance from the CDC on this issue are lacking.
Engineered inorganic nanoparticles and cosmetics: facts, issues, knowledge gaps and challenges.
Wiechers, Johann W; Musee, Ndeke
2010-10-01
The cosmetic industry is among the first adaptors of nanotechnology through the use of engineered nanoparticles (ENPs) to enhance the performance of their products and meet the customers' needs. Recently, there have been increasing concerns from different societal stakeholders (e.g., governments, environmental activist pressure groups, scientists, general public, etc.) concerning the safety and environmental impact of ENPs used in cosmetics. This review paper seeks to address the twin concerns of the safety of cosmetics and the potential environmental impacts due to the constituent chemicals-the ENPs. The safety aspect is addressed by examining recently published scientific data on the possibility of ENPs penetrating human skin. Data indicates that although particular types of ENPs can penetrate into the skin, until now no penetration has been detected beyond the stratum corneum of the ENPs used in cosmetics. Yet, important lessons can be learned from the more recent studies that identify the characteristics of ENPs penetrating into and permeating through human skin. On the part of the environmental impact, the scientific literature has very limited or none existent specific articles addressing the environmental impacts of ENPs owing to the cosmetic products. Therefore, general ecotoxicological data on risk assessment of ENPs has been applied to ascertain if there are potential environmental impacts from cosmetics. Results include some of the first studies on the qualitative and quantitative risk assessment of ENPs from cosmetics and suggest that further research is required as the knowledge is incomplete to make definitive conclusions as is the case with skin penetration. The authors conclude that the cosmetic industry should be more transparent in its use of nanotechnology in cosmetic products to facilitate realistic risk assessments as well as scientists and pressure groups being accurate in their conclusions on the general applicability of their findings. Transparency in cosmetics needs nanotechnology, but nanotechnology in cosmetics also needs transparency...

Abstract Background and Aims: Unintentional acetaminophen overdose remains the leading cause of acute liver failure in the United States. Patients with underlying liver disease are at higher risk of poor outcomes from acetaminophen overdose. Limited knowledge of acetaminophen may be a preventable contributor to elevated rates of overdose and thus acute liver failure. The purpose of this study is to assess knowledge of acetaminophen dosing and presence of acetaminophen in common combination products in patients with liver disease. Methods: We performed a cross-sectional study of patients with liver disease at the Pfleger Liver Institute at the University of California, Los Angeles between June 2015 and August 2016. Patients completed a demographic questionnaire and an acetaminophen knowledge survey. Additional information was obtained from the medical record. Results: Of 401 patients with liver disease, 30 (15.7%) were able to correctly identify that people without liver disease can safely take up to 4 g/day of acetaminophen. The majority of patients (79.9%–86.8%) did not know that Norco® (hydrocone/acetaminophen), Vicodin® (hydrocone/acetaminophen) and Percocet® (oxycodone/acetaminophen) contained acetaminophen. Only 45.3% of the patients knew that Tylenol® #3 contained acetaminophen. Conclusions: We conclude that patients with liver disease have critically low levels of knowledge of acetaminophen, putting them at risk both of acetaminophen overdose, as well as undermedication, and inadequate management of chronic pain. We recommend an increase in education efforts regarding acetaminophen dosage and its safety in the setting of liver disease. Increasing education for those at risk of low acetaminophen knowledge is essential to minimizing acetaminophen overdose rates and optimizing pain management. PMID:28097095

A cross-sectional survey was carried out among 91 meat handlers by using structured questionnaire to determine the food safety knowledge, attitude and practices in abattoir and retail meat shops of Jigjiga Town. The result shows that majority of the meat handlers were illiterate (30.8%) and primary school leaver (52.7%), and no one went through any food safety training except one meat inspector. The food-handlers' knowledge and safety practices were below acceptable level with the mean score of 13.12 ± 2.33 and 7.7 ± 2.1 respectively. Only few respondents knew about Staphylococcus aureus (3.3% correct answer), hepatitis A virus (19.8% correct answer), and E. coli (5.5% correct answer) as food borne pathogens. About 64% of meat handlers have good attitude about safety of food with mean of total score 14.4 ± 2. All respondents answer correctly questions about proper meat handling and hand washing but they did not translate into strict food hygiene practices. Chi2 analysis testing for the association between knowledge, attitude and practices did not show any significant association. It may be due to meat handlers' below acceptable level safety practices regardless of sociodemographic characteristics, knowledge and attitude. However, there was strong association between level of education and knowledge, and knowledge and hand washing (p < 0.05). There was also association between age and knowledge though it was not statistically significant. Thus, continuous education and hands on training for meat handlers that can enhance good safety practices through better understanding and positive attitude.

Prelicensure nursing students seeking to enter perioperative nursing need preparatory fire safety knowledge and skills training to participate as a member of an operating room (OR) team. This pilot study examined the effectiveness of the Virtual Electrosurgery Skill Trainer (VEST) on OR fire safety skills among prelicensure nursing students. An experimental pretest-posttest design was used in this study. Twenty nursing students were randomized to a control or an intervention group. Knowledge and skills acquisition of OR fire safety were assessed. There were no statistically significant findings in knowledge for either group. Fisher exact test demonstrated significant relationships between the skills performance criteria of following emergency procedures for a fire and demonstrating PASS (pull-aim-squeeze-sweep) technique (P = .001). Academic and hospital educators may consider incorporating virtual reality simulation to teach fire safety education or reinforce general fire safety practices to nursing students and novice nurses.
The 4Rs of Aquatic Rescue: educating the public about safety and risks of bystander rescue.
Moran, Kevin; Webber, Jonathon; Stanley, Teresa
2017-09-01
From 1980 to 2014, 87 persons drowned in New Zealand while attempting to rescue others; all incidents occurred in open water and most (80%) fatalities were male. While bystander rescue has been promoted as a way of preventing drowning, little is known about the knowledge base that informs potential rescuers. This study utilized a family water safety programme to promote a resource entitled the 4Rs of Aquatic Rescue. Participants (n = 174) completed a pre-intervention survey and were then provided with information and access to electronic resources on safe bystander rescue techniques. Most respondents (71%) had never been taught rescue techniques, and males were more confident of their rescue ability. Upon completion of the programme, significant differences were evident in respondents' understanding of rescue safety, but this did not translate to greater confidence or disposition towards performing a rescue. Ways of promoting bystander safety around water are discussed and recommendations for future studies are made.

Standards and regulations related to spirit drinks have been established by different countries and international organizations to ensure the safety and quality of spirits. Here, we introduce the principles of food safety and quality standards for alcoholic beverages and then compare the key indicators used in the distinct standards of the Codex Alimentarius Commission, the European Union, the People's Republic of China, the United States, Canada, and Australia. We also discuss in detail the "maximum level" of the following main contaminants of spirit drinks: methanol, higher alcohols, ethyl carbamate, hydrocyanic acid, heavy metals, mycotoxins, phthalates, and aldehydes. Furthermore, the control measures used for potential hazards are introduced. Harmonization of the current requirements based on comprehensive scope analysis and the risk assessment approach will enhance both the trade and quality of distilled spirits. This review article provides valuable information that will enable producers, traders, governments, and researchers to increase their knowledge of spirit drink safety requirements, control measures, and research trends.
Participatory/problem-based methods and techniques for training in health and safety.
Rosskam, E
2001-01-01
More knowledgeable and trained people are needed in the area of occupational health, safety, and environment (OSHE) if work-related fatalities, accidents, and diseases are to be reduced. Established systems have been largely ineffective, with few employers taking voluntary measures to protect workers and the environment and too few labor inspectors available. Training techniques using participatory methods and a worker empowerment philosophy have proven value. There is demonstrated need for the use of education for action, promoting the involvement of workers in all levels of decision-making and problem-solving in the workplace. OSH risks particular to women s jobs are virtually unstudied and not addressed at policy levels in most countries. Trade unions and health and safety professionals need to demystify technical areas, empower workers, and encourage unions to dedicate special activities around women s jobs. Trained women are excellent motivators and transmitters of safety culture. Particular emphasis is given to train-the-trainer approaches.
Survey of public perceptions of prion disease risks in Canada: what does the public care about?

A national public survey on public perceptions of prion disease risk in Canada was conducted from October to December 2007. The survey aimed at documenting the public's perceptions of prion diseases, within the broader context of food safety, in establishing parameters of risk acceptability. It also documented the public's perceptions of prion diseases in delineating social values and ethics that can guide Canada's future policies on prion disease risk management. In addition, the survey served to establish baseline data against which to monitor the evolution of the public's views on and understanding of this important risk issue. In total, 1517 Canadians were randomly selected to be representative of the adult population by region, age, and gender, as per the 2001 Census. This study presents descriptive findings from the survey regarding perceived risk, perceived control, uncertainty, sources of information, trust and knowledge, and beliefs pertaining to bovine spongiform encephalopathy (BSE). The survey data reveal that Canadians do not perceive mad cow disease as a salient risk but consider it more of an economic, political, social, and foreign trade issue than a public health one. Canadians are somewhat prepared to pay a premium to have a safer food supply, but not to the same extent that they desire extra measures pertaining to BSE risk management. In the context of increasing accountability in risk management decisions about food safety and population health issues, it is important to understand the way Canadians perceive such matters and identify their information needs and the factors that influence the acceptability of risks and of risk management policies.

Introduction Nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently associated with community-acquired acute kidney injury (AKI), a strong risk factor for development and progression of chronic kidney disease. Using access to prescription medication profiles, pharmacists can identify patients at high risk for NSAID-induced AKI. The primary objective of this analysis was to evaluate the effectiveness of a community pharmacy–based patient education program on patient knowledge of NSAID-associated renal safety concerns. Methods Patients receiving prescription medications for hypertension or diabetes mellitus were invited to participate in an educational program on the risks of NSAID use. A patient knowledge questionnaire (PKQ) consisting of 5 questions scored from 1 to 5 was completed before and after the intervention. Information was collected on age, race, sex, and frequency of NSAID use. Results A total of 152 participants (60% women) completed both the pre- and post-intervention questionnaire; average age was 54.6 (standard deviation [SD], 17.5). Mean pre-intervention PKQ score was 3.3 (SD, 1.4), and post-intervention score was 4.6 (SD, 0.9) (P = .002). Participants rated program usefulness (1 = not useful to 5 = extremely useful) as 4.2 (SD, 1.0). In addition, 48% reported current NSAID use and 67% reported that the program encouraged them to limit their use. Conclusion NSAID use was common among patients at high risk for AKI. A brief educational intervention in a community pharmacy improved patient knowledge on NSAID-associated risks. Pharmacists practicing in the community can partner with primary care providers in the medical home model to educate patients at risk for AKI. PMID:25523351

2004-12-01
The present study assessed smokers' beliefs about the health risks of smoking and the benefits of smoking filtered and low-tar cigarettes, and their awareness of and interest in trying so-called reduced-risk tobacco products. Results were based on a nationally representative random-digit-dialed telephone survey of 1,046 adult (aged 18 years or older) current cigarette smokers. Data were gathered on demographic characteristics, tobacco use behaviors, awareness and use of nicotine medications, beliefs about the health risks of smoking, content of smoke and design features of cigarettes, and the safety and efficacy of nicotine medications. In addition, respondents were asked about their interest in and perceived ability to stop smoking and about their desire for more information about the health risks of smoking. Smokers were least knowledgeable about low-tar and filter cigarettes (65% of responses were incorrect or "don't know") and most knowledgeable about the health risks of smoking (39% of responses were incorrect or "don't know"). The smokers' characteristics most commonly associated with misinformation when all six indices were combined into a summary index were as follows: those aged 45 years or older, smokers of ultralight cigarettes, smokers who believe they will stop smoking before they experience a serious health problem caused by smoking, smokers who have never used a stop-smoking medication, and smokers with a lower education level. Those who believed they would stop smoking in the next year were more knowledgeable about smoking. Some 77% of respondents reported a desire for additional information from tobacco companies on the health dangers of smoking. The present findings demonstrate that smokers are misinformed about many aspects of the cigarettes they smoke and stop-smoking medications and that they want more information about ways to reduce their health risks.
[The protection of health in law enforcement].
Pira, Enrico
2014-01-01
Herein the question of health protection/safety and well being in the Law Enforcement is introduced and includes examples of some particular risk conditions that may be multiple and polymorphous. Not only the "traditional" sources are involved in these risks, like chemical, physical and biological agents, but other issues emerge in these "new scenarios" connected to risk factors involving organization and/or psychosocial elements. From this, we may deduce that there is a specific need for all the operators involved in prevention/care in this particular sector to be well versed on the highest possible updated specialized knowledge along with having a complete and thorough mastery of the best practices in Occupational Medicine to face this task in the correct manner:

WHAT IS KNOWN ON THE SUBJECT?: Risk assessment and safety planning are a core aspect of the role of the mental health nurse. Conflicting views exist on the value of risk assessment tools. Few studies have examined mental health nurses' attitudes towards risk, including use of tools and the role of positive risk in recovery. WHAT THE PAPER ADDS TO EXISTING KNOWLEDGE?: Mental health nurses view risk assessment as a core dimension of their role and not merely an exercise to fulfil organizational clinical safety and governance obligations. The majority of nurses hold positive attitudes towards therapeutic or positive risk, and consider creative risk taking as vital to people's recovery. The majority of nurses believe that risk assessment tools facilitate professional decision making, however, some are concerned that tools may negatively impact upon therapeutic relationships. WHAT ARE THE IMPLICATIONS FOR PRACTICE?: Ongoing education on the use of risk assessment tools is required to minimize views that their use is incompatible with therapeutic engagement, and to enable nurses to develop confidence to engage with positive risk and to allow service users make decisions and take responsibility. Introduction Risk assessment and safety planning are considered core components of the role of the mental health nurse; however, little is known about nurses' attitudes towards risk assessment, use of tools to assess risk or therapeutic risk taking. Aim This study aimed to explore mental health nurses' attitudes towards completing risk assessments, use of tools as an aid, and therapeutic or positive risk. Method An anonymous survey which included 13 attitudinal statements, rated on a five-point Likert scale, was completed by 381 mental health nurses working in adult services in Ireland. Findings Findings indicate strong support for the practice of risk assessment in mental health practice. The vast majority of nurses believe that risk assessment tools facilitate professional decision making; however, there is concern that the use of these tools may negatively impact upon therapeutic engagement with service users. The majority of participants have positive attitudes towards therapeutic risk, believing that service users have the right to take informed risks in the context of recovery-orientated care. Discussion The provision of education on the use of risk assessment tools within the context of engagement may help minimize views that the use of assessment tools are incompatible with therapeutic engagement. © 2016 John Wiley & Sons Ltd.
Food Safety Challenges towards Safe, Healthy, and Nutritious Street Foods in Bangladesh
Khairuzzaman, Md.; Zaman, Sharmin; Al Mamun, Arafat; Bari, Md. Latiful
2014-01-01
The street foods play an important socioeconomic role in meeting food and nutritional requirements of city consumers at affordable prices to the lower and middle income people. The number of food poisoning notifications rose steadily worldwide since the inception of E. coli O157:H7 outbreak in the 1980s to date. This may be partly attributed to improved surveillance, increased global trade and travel, changes in modern food production, the impact of modern lifestyles, changes in food consumption, and the emergence of new pathogens. Consumer's knowledge and attitude may influence food safety behavior and practice. For the sake of public health, it is important to understand the epidemiology of foodborne illnesses that help in prevention and control efforts, appropriately allocating resources to control foodborne illness, monitoring and evaluation of food safety measures, development of new food safety standards, and assessment of the cost-effectiveness of interventions. This review paper described the sociodemographic characteristics, common hazards, and occupational hazards of street food vendors, microbial risk associated with street food, food safety interventions and control measures, regulatory aspects and legal requirements, financial constraints, and attitudes.

Food safety challenges and One Health within Europe.
Boqvist, Sofia; Söderqvist, Karin; Vågsholm, Ivar
2018-01-03
This review discusses food safety aspects of importance from a One Health perspective, focusing on Europe. Using examples of food pathogen/food commodity combinations, spread of antimicrobial resistance in the food web and the risk of transmission of zoonotic pathogens in a circular system, it demonstrates how different perspectives are interconnected. The chosen examples all show the complexity of the food system and the necessity of using a One Health approach. Food safety resources should be allocated where they contribute most One Health benefits. Data on occurrence and disease burden and knowledge of source attribution are crucial in assessing costs and benefits of control measures. Future achievements in food safety, public health and welfare will largely be based on how well politicians, researchers, industry, national agencies and other stakeholders manage to collaborate using the One Health approach. It can be concluded that closer cooperation between different disciplines is necessary to avoid silo thinking when addressing important food safety challenges. The importance of this is often mentioned, but more proof of concept is needed by the research community.

The Department of Defense has an increasing number of high-energy laser weapons programs with the potential to mature in the not too distant future. However, as laser systems with increasingly higher energies are developed, the difficulty of the laser safety problem increases proportionally, and presents unique safety challenges. The hazard distance for the direct beam can be in the order of thousands of miles, and radiation reflected from the target may also be hazardous over long distances. This paper details the Air Force Research Laboratory/Optical Radiation Branch (AFRL/HEDO) High-Energy Laser (HEL) safety program, which has been developed to support DOD HEL programs by providing critical capability and knowledge with respect to laser safety. The overall aim of the program is to develop and demonstrate technologies that permit safe testing, deployment and use of high-energy laser weapons. The program spans the range of applicable technologies, including evaluation of the biological effects of high-energy laser systems, development and validation of laser hazard assessment tools, and development of appropriate eye protection for those at risk.
[Prevention of road accidents in the road haulage field].

Every year many traffic accidents with fatal outcomes occur in our Country. According to the recent indications of the European Agency for Safety and Health at Work, the Piedmont region has financed the plan: Prevention of road accidents in the road haulage field. The aims of the plan are to stimulate transport companies to the target of road safety and to improve and enforce sanitary surveillance, in order to improve the safety on road haulage and to prevent traffic injuries. the plan foresees, over a period of two years, a few encounters with all the interested parties (companies, police forces, labour unions etc). During those encounters we have to give a questionnaire for evaluating the companies' knowledge about the problem and we have to choose a common plan with the aim of improving road safety. The Piedmont regional plan recalls the need to increase the attention to numerous and diversified hazards for safety on road haulage. It also imposes the choice of measures that include: risk assessment, health education, technical and environmental prevention, sanitary surveillance and clinical interventions (diagnosis and rehabilitation of occupational accidents).
Light-emitting diodes (LED) for domestic lighting: any risks for the eye?

Light-emitting diodes (LEDs) are taking an increasing place in the market of domestic lighting because they produce light with low energy consumption. In the EU, by 2016, no traditional incandescent light sources will be available and LEDs may become the major domestic light sources. Due to specific spectral and energetic characteristics of white LEDs as compared to other domestic light sources, some concerns have been raised regarding their safety for human health and particularly potential harmful risks for the eye. To conduct a health risk assessment on systems using LEDs, the French Agency for Food, Environmental and Occupational Health & Safety (ANSES), a public body reporting to the French Ministers for ecology, for health and for employment, has organized a task group. This group consisted physicists, lighting and metrology specialists, retinal biologist and ophthalmologist who have worked together for a year. Part of this work has comprised the evaluation of group risks of different white LEDs commercialized on the French market, according to the standards and found that some of these lights belonged to the group risk 1 or 2. This paper gives a comprehensive analysis of the potential risks of white LEDs, taking into account pre-clinical knowledge as well as epidemiologic studies and reports the French Agency's recommendations to avoid potential retinal hazards.

Patient safety is an increasing concern for health systems internationally. The majority of administrative work in UK general practice takes place in the context of organisational routines such as repeat prescribing and test results handling, where high workloads and increased clinician dependency on administrative staff have been identified as an emerging safety issue. Despite this trend, most research to date has focused on the redistribution of the clinical workload between doctors, nurses and allied health professionals within individual care settings. Drawing on Strauss's negotiated order perspective, we examine ethnographically the achievement of safety across the medical-administrative boundary in key high-volume routines in UK general practice. We focus on two main issues. First, GPs engaged in strategies of demarcation by defining receptionist work as routine, unspecialised and dependent upon GP clinical knowledge and oversight as the safety net to deal with complexity and risk. Receptionists consented to this 'social closure' when describing their role, thus reinforcing the underlying inter-occupational relationship of medical domination. Second, in everyday practice, GPs and receptionists engaged in informal boundary-blurring to safely accommodate the complexity of everyday high-volume routine work. This comprised additional informal discretionary spaces for receptionist decision-making and action that went beyond the routine safety work formally assigned to them. New restratified intra-occupational hierarchies were also being created between receptionists based on the complexity of the safety work that they were authorised to do at practice level, with specialised roles constituting a new form of administrative 'professional project'. The article advances negotiated order theory by providing an in-depth examination of the ways in which medical-administrative boundary-making and boundary-blurring constitute distinct modes of safety in high-volume routines. It also provides the basis for further research and safety improvement to maximise team-level understandings of the pivotal role of medical-administrative negotiations in achieving safety and mitigating risk.

The need for detailed gender-specific occupational safety analysis.
Cruz Rios, Fernanda; Chong, Wai K; Grau, David
2017-09-01
The female work in population is growing in the United States, therefore the occupational health and safety entities must start to analyze gender-specific data related to every industry, especially to nontraditional occupations. Women working in nontraditional jobs are often exposed to extreme workplace hazards. These women have their safety and health threatened because there are no adequate policies to mitigate gender-specific risks such as discrimination and harassment. Employers tend to aggravate this situation because they often fail to provide proper reporting infrastructure and support. According to past studies, women suffered from workplace injuries and illnesses that were less prominent among men. Statistics also confirmed that men and women faced different levels of risks in distinct work environments. For example, the rates of workplace violence and murders by personal acquaintances were significantly higher among women. In this paper, the authors analyze prior public data on fatal and nonfatal injuries to understand why we need to differentiate genders when analyzing occupational safety and health issues. The analyses confirmed that women dealt with unique workplace hazards compared to men. It is urgent that public agencies, such as the U.S. Department of Labor, record gender-specific data in details and by occupations and industries. The reader will become aware of the current lack - and need - of data and knowledge about injuries and illnesses separated by gender and industry. Finally, safety and health researchers are encouraged to investigate the gender-specific data in all industries and occupations, as soon as they become available.

This exploratory qualitative study was conducted to identify constraints to microbial food safety policy in Canada and the USA from the perspective of stakeholder groups along the farm to fork continuum. Thirty-seven stakeholders participated in interviews or a focus group where semi-structured questions were used to facilitate discussion about constraints to policy development and implementation. An emergent grounded theory approach was used to determine themes and concepts that arose from the data (versus fitting the data to a hypothesis or a priori classification). Despite the plurality of stakeholders and the range of content expertise, participant perceptions emerged into five common themes, although, there were often disagreements as to the positive or negative attributes of specific concepts. The five themes included challenges related to measurement and objectives of microbial food safety policy goals, challenges arising from lack of knowledge, or problems with communication of knowledge coupled with current practices, beliefs and traditions; the complexity of the food system and the plurality of stakeholders; the economics of producing safe food and the limited resources to address the problem; and, issues related to decision-making and policy, including ownership of the problem and inappropriate inputs to the decision-making process. Responsibilities for food safety and for food policy failure were attributed to all stakeholders along the farm to fork continuum. While challenges regarding the biology of food safety were identified as constraints, a broader range of policy inputs encompassing social, economic and political considerations were also highlighted as critical to the development and implementation of effective food safety policy. Strategies to address these other inputs may require new, transdisciplinary approaches as an adjunct to the traditional science-based risk assessment model.

Kang, Nam-E; Kim, Ju Hyeon; Kim, Young Soon
2010-01-01
In this study, 342 grade 4-6 elementary school students in Gyeonggi-do were recruited to determine their readiness to change food safety behavior and to compare their food safety knowledge and practices by the stages of change. The subjects were divided into three stages of change; the percentage of stage 1 (precontemplation) was 10.1%, the percentage of stage 2 (contemplation and preparation) was 62.4%, and that of stage 3 (action and maintenance) was 27.5%. Food safety knowledge scores in stage 3 (4.55) or stage 2 (4.50) children were significantly higher than those in stage 1 children (4.17) (P < 0.05). The two food safety behavior items "hand washing practice" and "avoidance of harmful food" were significantly different among the three groups (P < 0.05). Stages of change were significantly and positively correlated with food safety knowledge and practice. Age was significantly and negatively correlated with the total food safety behavior score (r = -0.142, P < 0.05). The most influential factor on the stage of change was a mother's instruction about food safety (P < 0.01). PMID:21286413
The FITS model office ergonomics program: a model for best practice.
Chim, Justine M Y
2014-01-01
An effective office ergonomics program can predict positive results in reducing musculoskeletal injury rates, enhancing productivity, and improving staff well-being and job satisfaction. Its objective is to provide a systematic solution to manage the potential risk of musculoskeletal disorders among computer users in an office setting. A FITS Model office ergonomics program is developed. The FITS Model Office Ergonomics Program has been developed which draws on the legislative requirements for promoting the health and safety of workers using computers for extended periods as well as previous research findings. The Model is developed according to the practical industrial knowledge in ergonomics, occupational health and safety management, and human resources management in Hong Kong and overseas. This paper proposes a comprehensive office ergonomics program, the FITS Model, which considers (1) Furniture Evaluation and Selection; (2) Individual Workstation Assessment; (3) Training and Education; (4) Stretching Exercises and Rest Break as elements of an effective program. An experienced ergonomics practitioner should be included in the program design and implementation. Through the FITS Model Office Ergonomics Program, the risk of musculoskeletal disorders among computer users can be eliminated or minimized, and workplace health and safety and employees' wellness enhanced.
An update on the safety of nutraceuticals and effects on lipid parameters.
Cicero, Arrigo F G; Colletti, Alessandro
2018-03-01
Cardiovascular diseases (CVDs) are the leading cause of mortality and disability in developed countries, whereas a large portion of patients in primary prevention have uncontrolled level of CVD risk factors. Dietary supplementation with bioactive natural compounds with demonstrated lipid-lowering effects is currently supported by the international guidelines for CVD prevention and some international expert panels. Areas covered: This review provides insights on issues concerning the tolerability and safety of the most commonly used nutraceuticals with demonstrated lipid-lowering effect in humans. They will be then divided into three main categories according to their mechanism of action (cholesterol synthesis inhibitors, intestinal cholesterol absorption inhibitors, and LDL-C excretion stimulants) and their pharmacological profile will be discussed. Expert opinion: A growing body of preclinical, epidemiological and clinical evidence has defined the tolerability and safety profile of the most commonly used lipid-lowering nutraceuticals. In the most part of cases, the side effects are mild and reversible. However, detailed knowledge of specific health risks and pharmacological interactions for each individual compound is needed for the management of frail patients, such as children, elderly, patients with liver or renal failure, and patients consuming numerous drugs.
The role of bromocriptine-QR in the management of type 2 diabetes expert panel recommendations.
Garber, Alan J; Blonde, Lawrence; Bloomgarden, Zachary T; Handelsman, Yehuda; Dagogo-Jack, Samuel
2013-01-01
To review available data on the efficacy and safety of bromocriptine-QR (BQR) and to consider its role in the management of Type 2 diabetes mellitus (T2DM). Published literature reporting the efficacy and safety of BQR in the treatment of T2DM was reviewed, including peer-reviewed abstracts and poster presentations. BQR is an oral hypoglycemic agent with a novel mechanism of action that appears to involve enhancement of morning central nervous system (CNS) dopaminergic activity, resulting in improved insulin sensitivity and reduced hepatic glucose output. Adjunctive treatment with BQR in the dosing range of 1.6 to 4.8 mg/d may result in a mean (95% confidence interval [CI]) reduction in glycated hemoglobin (A1c) levels of 0.69% (0.97%, 0.41%). Treatment with BQR appears to be associated with minimal intrinsic risk of hypoglycemia, and does not appear to be associated with clinically significant adverse effects on weight, triglycerides, free fatty acids, or blood pressure. The favorable cardiovascular risk profile of BQR suggests that it may be useful in the treatment of patients with T2DM with a history of cardiovascular disease (CVD) or who have significant risk factors for CVD. However, knowledge of the efficacy and safety of BQR is limited by the relatively small clinical trials database. As a result, there is currently insufficient information on the safety and efficacy of adjunctive BQR in T2DM patients being treated with several common diabetes regimens (e.g., thiazolidinediones, insulin).
Revisiting Pneumatic Nail Gun Trigger Recommendations
Albers, James; Lipscomb, Hester; Hudock, Stephen; Dement, John; Evanoff, Bradley; Fullen, Mark; Gillen, Matt; Kaskutas, Vicki; Nolan, James; Patterson, Dennis; Platner, James; Pompeii, Lisa; Schoenfisch, Ashley

Summary Use of a pneumatic nail gun with a sequential actuation trigger (SAT) significantly diminishes the risk for acute traumatic injury compared to use of a contact actuation trigger (CAT) nail gun. A theoretically-based increased risk of work-related musculoskeletal disorders from use of a SAT nail gun, relative to CAT, appears unlikely and remains unproven. Based on current knowledge, the use of CAT nail guns cannot be justified as a safe alternative to SAT nail guns. This letter provides a perspective of ergonomists and occupational safety researchers recommending the use of the sequential actuation trigger for all nail gun tasks in the construction industry.

This study examines demographic, cognitive and behavioral factors that predict pediatric dog-bite injury risk in rural China. A total of 1,537 children (grades 4–6) in rural regions of Anhui, Hebei and Zhejiang Provinces, China completed self-report questionnaires assessing beliefs about and behaviors with dogs. The results showed that almost 30% of children reported a history of dog bites. Children answered 56% of dog-safety knowledge items correctly. Regressions revealed both demographic and cognitive/behavioral factors predicted children’s risky interactions with dogs and dog-bite history. Boys behaved more riskily with dogs and were more frequently bitten. Older children reported greater risks with dogs and more bites. With demographics controlled, attitudes/beliefs of invulnerability, exposure frequency, and dog ownership predicted children’s self-reported risky practice with dogs. Attitudes/beliefs of invulnerability, dog exposure, and dog ownership predicted dog bites. In conclusion, both demographic and cognitive/behavioral factors influenced rural Chinese children’s dog-bite injury risk. Theory-based, empirically-supported intervention programs might reduce dog-bite injuries in rural China. PMID:23470881
Paracetamol in Older People: Towards Evidence-Based Dosing?
Mian, Paola; Allegaert, Karel; Spriet, Isabel; Tibboel, Dick; Petrovic, Mirko
2018-06-19
Paracetamol is the most commonly used analgesic in older people, and is mainly dosed according to empirical dosing guidelines. However, the pharmacokinetics and thereby the effects of paracetamol can be influenced by physiological changes occurring with ageing. To investigate the steps needed to reach more evidence-based paracetamol dosing regimens in older people, we applied the concepts used in the paediatric study decision tree. A search was performed to retrieve studies on paracetamol pharmacokinetics and safety in older people (> 60 years) or studies that performed a (sub) analysis of pharmacokinetics and/or safety in older people. Of 6088 articles identified, 259 articles were retained after title and abstract screening. Further abstract and full-text screening identified 27 studies, of which 20 described pharmacokinetics and seven safety. These studies revealed no changes in absorption with ageing. A decreased (3.9-22.9%) volume of distribution (V d ) in robust older subjects and a further decreased V d (20.3%) in frail older compared with younger subjects was apparent. Like V d , age and frailty decreased paracetamol clearance (29-45.7 and 37.5%) compared with younger subjects. Due to limited and heterogeneous evidence, it was difficult to draw firm and meaningful conclusions on changed risk for paracetamol safety in older people. This review is a first step towards bridging knowledge gaps to move to evidence-based paracetamol dosing in older subjects. Remaining knowledge gaps are safety when using therapeutic dosages, pharmacokinetics changes in frail older people, and to what extent changes in paracetamol pharmacokinetics should lead to a change in dosage in frail and robust older people.

Every year many people around the world become infected with food-borne infections. Insufficient knowledge and skills related to food safety and hygiene are among the factors affecting the incidence of food-borne diseases, especially in adolescents. The purpose of this study was to determine the knowledge and practices associated with food safety and hygiene in Ilam city male adolescents. Three hundred and eighty of male adolescents aged 13 to 19 were selected randomly and entered the cross-sectional study. Data were collected using a researcher-made questionnaire From December 2016 to February 2017. Descriptive statistics, Pearson correlation, independent t-test and one-way ANOVA were used to analyse the data in SPSS software (version 19.0). The findings of the study showed a positive and significant relationship between knowledge and practices related to food safety and hygiene (r = 0.122; p = 0.018). Also, the findings showed that food safety knowledge and practice of adolescents were significantly affected by the level of their education, parental education level, parental employment status and household economic conditions, (p < 0.005). Also, the results showed that the participants generally obtained 57.74% of the knowledge score and 57.63% of practices score. The subjects had the most knowledge about food supply and storage (60%), and the highest practice was related to personal and environmental hygiene, (61.73%). The inadequacy of knowledge and performance of adolescents about food safety and hygiene shows the need for implementation of health education interventions in this area.
Patient Safety in Medical Education: Students’ Perceptions, Knowledge and Attitudes

Patient safety is a new and challenging discipline in the Iranian health care industry. Among the challenges for patient safety improvement, education of medical and paramedical students is intimidating. The present study was designed to assess students’ perceptions of patient safety, and their knowledge and attitudes to patient safety education. This cross-sectional analytical study was conducted in 2012 at Urmia University of Medical Sciences, West Azerbaijan province, Iran. 134 students studying medicine, nursing, and midwifery were recruited through census for the study. A questionnaire was used for collecting data, which were then analyzed through SPSS statistical software (version 16.0), using Chi-square test, Spearman correlation coefficient, F and LSD tests. A total of 121 questionnaires were completed, and 50% of the students demonstrated good knowledge about patient safety. The relationships between students’ attitudes to patient safety and years of study, sex and course were significant (0.003, 0.001 and 0.017, respectively). F and LSD tests indicated that regarding the difference between the mean scores of perceptions of patient safety and attitudes to patient safety education, there was a significant difference among medical and nursing/midwifery students. Little knowledge of students regarding patient safety indicates the inefficiency of informal education to fill the gap; therefore, it is recommended to consider patient safety in the curriculums of all medical and paramedical sciences and formulate better policies for patient safety.

Many unintentional injuries that occur in and around the home can be prevented through the use of safety equipment and by consistently following existing safety recommendations. Unfortunately, uptake of these safety behaviors is unacceptably low. This paper describes the design of the Make Safe Happen® smartphone application evaluation study, which aims to evaluate a mobile technology-based safety behavior change intervention on parents' safety knowledge and actions. Make Safe Happen® app evaluation study is a randomized controlled trial. Participants will be parents of children aged 0-12 years who are recruited from national consumer online survey panels. Parents will complete a pretest survey, and will be randomized to receive the Make Safe Happen® app or a non-injury-related app, and then complete a posttest follow-up survey after 1 week. Primary outcomes are: (1) safety knowledge; (2) safety behaviors; (3) safety device acquisition and use, and (4) behavioral intention to take safety actions. Anticipated study results are presented. Wide-reaching interventions, to reach substantial parent and caregiver audiences, to effectively reduce childhood injuries are needed. This study will contribute to the evidence-base about how to increase safety knowledge and actions to prevent home-related injuries in children. NCT02751203 ; Pre-results.

The inherent and unique risks on construction projects quite often present key challenges to contractors. Health and safety risks are among the most significant risks in construction projects since the construction industry is characterized by a relatively high injury and death rate compared to other industries. In construction project management, safety risk assessment is an important step toward identifying potential hazards and evaluating the risks associated with the hazards. Adequate prioritization of safety risks during risk assessment is crucial for planning, budgeting, and management of safety related risks. In this paper, a safety risk assessment framework is presented based on the theory of cost of safety (COS) model and the analytic hierarchy process (AHP). The main contribution of the proposed framework is that it presents a robust method for prioritization of safety risks in construction projects to create a rational budget and to set realistic goals without compromising safety. The framework provides a decision tool for the decision makers to determine the adequate accident/injury prevention investments while considering the funding limits. The proposed safety risk framework is illustrated using a real-life construction project and the advantages and limitations of the framework are discussed.

The purpose of this paper is to describe patterns of patient safety culture that emerged from an innovative collaboration among health services researchers and fine arts colleagues. The group engaged in an arts-informed knowledge translation project to produce a dramatic expression of patient safety culture research for inclusion in a symposium. Scholars have called for a deeper understanding of the complex interrelationships among structure, process and outcomes relating to patient safety. Four patterns of patient safety culture--blinding familiarity, unyielding determination, illusion of control and dismissive urgency--are described with respect to how they informed creation of an arts-informed project for knowledge translation.

Thirty years ago the world of Commercial Aviation provided a challenging environment. In my early flying days, aircraft accidents were not unusual, flying was seen as a risky business and those who took part, either as a provider or passenger, appeared grudgingly willing to accept the hazards involved. A reduction in the level of risk was sought in technological advances, greater knowledge of physics and science, and access to higher levels of skill through simulation, practice and experience. While these measures did have an impact, the expected safety dividend was not realized. The most experienced, technically competent individuals with the best equipment featured far too regularly in the accident statistics. We had to look at the human element, the impact of flaws or characteristics of the human condition. We call this area Human Factors. My paper describes the concept of Human Factors, its establishment as a key safety tool in aviation and the impact of this on my working life.

Unintentional injury is the leading cause of death for those aged 0 years to 19 years. St. Louis Children's Hospital created Safety Land, a comprehensive injury prevention intervention which is provided during summer months. This program uses a life-size board game to teach safety education to children in ages 5 years to 11 years. The purpose of this study was to evaluate the effect of Safety Land on safety knowledge in children that participated in the intervention. St. Louis Children's Hospital identified ZIP codes with the highest use of the emergency room for injury. Daycares and summer camps within these ZIP codes were targeted for the Safety Land intervention. A multiple choice pretest and posttest survey was designed to measure knowledge change within program participants. Students were selected for testing based on site availably. Within these sites, a convenience sample of children was selected for pretesting and posttesting. Safety Land staff conducted the pretest a week before the intervention, and the posttest was administered the week after the intervention. A total knowledge score was calculated to determine overall knowledge change. Descriptive statistics and independent-samples t tests were conducted to determine statistical significance of change in knowledge (p < 0.05) for each question. Between May 2014 and August 2016, 3,866 children participated in Safety Land. A total of 310 children completed the pretest and 274 completed the posttest. Mean test scores increased from 66.7% to 85.1% and independent-samples t test of the total knowledge score was significant (p < 0.05) between pretest and posttest values. Findings suggest that this intervention is effective in increasing the knowledge of safety behaviors for children receiving the curriculum during the summer months. Further research should focus on long-term behavior changes in these youth.

The sociotechnical systems perspective offers intriguing and potentially valuable insights into problems associated with workplace safety. While formal sociotechnical systems thinking originated in the 1950s, its application to the analysis and design of sustainable, safe working environments has not been fully developed. To that end, a Hopkinton Conference was organised to review and summarise the state of knowledge in the area and to identify research priorities. A group of 26 international experts produced collaborative articles for this special issue of Ergonomics, and each focused on examining a key conceptual, methodological and/or theoretical issue associated with sociotechnical systems and safety. In this concluding paper, we describe the major conference themes and recommendations. These are organised into six topic areas: (1) Concepts, definitions and frameworks, (2) defining research methodologies, (3) modelling and simulation, (4) communications and decision-making, (5) sociotechnical attributes of safe and unsafe systems and (6) potential future research directions for sociotechnical systems research. Sociotechnical complexity, a characteristic of many contemporary work environments, presents potential safety risks that traditional approaches to workplace safety may not adequately address. In this paper, we summarise the investigations of a group of international researchers into questions associated with the application of sociotechnical systems thinking to improve worker safety.

There is a lack of basic knowledge on the part of both clinicians and patients as to the indications for use and safety of herbs used during pregnancy and lactation. This is one article in a series that systematically reviews the evidence for herbs commonly used during pregnancy and lactation. To systematically review the literature for evidence on the use, safety and pharmacology of cranberry, focusing on issues pertaining to pregnancy and lactation. We searched 7 electronic databases and compiled data according to the grade of evidence found. There is no direct evidence of safety or harm to the mother or fetus as a result of consuming cranberry during pregnancy. Indirectly, there is good scientific evidence that cranberry may be of minimal risk, where a survey of 400 pregnant women did not uncover any adverse events when cranberry was regularly consumed. In lactation, the safety or harm of cranberry is unknown. Women experience urinary tract infections with greater frequency during pregnancy. Given the evidence to support the use of cranberry for urinary tract infections (UTIs) and its safety profile, cranberry supplementation as fruit or fruit juice may be a valuable therapeutic choice in the treatment of UTIs during pregnancy.
Current safety practices in nano-research laboratories in China.

China has become a key player in the global nanotechnology field, however, no surveys have specifically examined safety practices in the Chinese nano-laboratories in depth. This study reports results of a survey of 300 professionals who work in research laboratories that handle nanomaterials in China. We recruited participants at three major nano-research laboratories (which carry out research in diverse fields such as chemistry, material science, and biology) and the nano-chemistry session of the national meeting of the Chinese Chemical Society. Results show that almost all nano-research laboratories surveyed had general safety regulations, whereas less than one third of respondents reported having nanospecific safety rules. General safety measures were in place in most surveyed nano-research laboratories, while nanospecific protective measures existed or were implemented less frequently. Several factors reported from the scientific literature including nanotoxicology knowledge gaps, technical limitations on estimating nano-exposure, and the lack of nano-occupational safety legislation may contribute to the current state of affairs. With these factors in mind and embracing the precautionary principle, we suggest strengthening or providing nanosafety training (including raising risk awareness) and establishing nanosafety guidelines in China, to better protect personnel in the nano-workplace.

People with HIV in India frequently encounter discrimination while seeking and receiving healthcare services. The knowledge and attitudes of healthcare workers (HCWs) influences the willingness and ability of people with HIV to access care, and the quality of the care they receive. Previous studies of HIV-related knowledge and attitudes amongst Indian HCWs have been conducted primarily in large urban hospitals. The objective of this study was to asses HIV-related knowledge, attitudes and risk perception among a group of rural north Indian HCWs, and to identify predictors of willingness to provide care for patients with HIV infection. A cross-sectional survey of 266 HCWs (78% female) from seven rural north Indian health settings was undertaken in late 2002. A self-administered written questionnaire was made available in English and Hindi, and the response rate was 87 per cent. Information was gathered regarding demographic details (age, sex, duration of employment, job category); HIV-related knowledge and attitudes; risk perception; and previous experience caring for HIV-positive patients. Logistic regression modelling was undertaken to identify factors associated with willingness to care for patients with HIV. The HCWs in this study generally had a positive attitude to caring for people with HIV. However, this was tempered by substantial concerns about providing care, and the risk of occupational infection with HIV was perceived by most HCWs to be high. After controlling for confounding, HCWs willingness to provide care for patients with HIV was strongly associated with having previously cared for patients with HIV (P = 0.001). Knowledge of HIV transmission and perception of risk were not associated with willingness to provide care. The findings of this study showed a general willingness of HCWs to provide care for patients with HIV, tempered by concerns regarding provision of such care. Strategies to address HCWs concerns are likely to ameliorate the discrimination experienced by people with HIV when accessing healthcare services. These include the development of programmes to promote occupational safety of HCWs and involving people with HIV in awareness training of HCWs.

An increasing number of people with dementia are ageing at home in Sweden and in other countries. In order to meet the safety requirements, knowledge about how persons with dementia experience risks is required. The aim of the study was to explore and better understand how persons with dementia, living at home, experience risks in their daily life and how they handle these situations. Twelve persons with dementia were interviewed using open-ended questions, and the data were analyzed using a content analysis approach. Findings showed that participants experienced situations fraught with risks in their daily life as unfamiliar and confusing. Previously familiar places became unfamiliar to them, and details did not come together. They were uncertain about what actually had happened. How the participants handled these situations in order to reduce the risks are described.

We conducted a study using a face-to-face survey to assess knowledge, attitudes, and practices of environmental service workers (ESWs) concerning routine cleaning and disinfection at 3 tertiary hospitals in China. There were 115 (89.1%) respondents who agreed that environmental cleaning can contribute to keep patients safe, whereas 63 (48.8%) reported they were very willing to make cleaning practices better. Only 15 (11.6%) ESWs agreed they were in risk of nosocomial infections during daily cleaning. Our findings suggest that the level of ESWs' knowledge regarding cleaning practices was passable, but the awareness of occupational safety and health was weak. There is a need to introduce sustained education and training aimed at ESWs. Copyright © 2017 Association for Professionals in Infection Control and Epidemiology, Inc. Published by Elsevier Inc.

Knowledge Management is a proactive pursuit for the future success of any large organization faced with the imminent possibility that their senior managers/engineers with gained experiences and lessons learned plan to retire in the near term. Safety and Mission Assurance (S&MA) is proactively pursuing unique mechanism to ensure knowledge learned is retained and lessons learned captured and documented. Knowledge Capture Event/Activities/Management helps to provide a gateway between future retirees and our next generation of managers/engineers. S&MA hosted two Knowledge Capture Events during 2005 featuring three of its retiring fellows (Axel Larsen, Dave Whittle and Gary Johnson). The first Knowledge Capture Event February 24, 2005 focused on two Safety and Mission Assurance Safety Panels (Space Shuttle System Safety Review Panel (SSRP); Payload Safety Review Panel (PSRP) and the latter event December 15, 2005 featured lessons learned during Apollo, Skylab, and Space Shuttle which could be applicable in the newly created Crew Exploration Vehicle (CEV)/Constellation development program. Gemini, Apollo, Skylab and the Space Shuttle promised and delivered exciting human advances in space and benefits of space in people s everyday lives on earth. Johnson Space Center's Safety & Mission Assurance team work over the last 20 years has been mostly focused on operations we are now beginning the Exploration development program. S&MA will promote an atmosphere of knowledge sharing in its formal and informal cultures and work processes, and reward the open dissemination and sharing of information; we are asking "Why embrace relearning the "lessons learned" in the past?" On the Exploration program the focus will be on Design, Development, Test, & Evaluation (DDT&E); therefore, it is critical to understand the lessons from these past programs during the DDT&E phase.

The objective of this study was to determine the impact of a community based fire prevention intervention directed only to parents on the fire safety knowledge and behavior in elementary school children. This was a prospective, quasi‐randomized controlled study in which third and fourth grade students from two elementary schools in an urban, poor, minority community completed knowledge/behavior surveys at baseline and following completion of the intervention. The intervention group received an in‐home visit from fire department personnel who installed free lithium smoke detectors and provided a fire escape plan. After accounting for a small difference in baseline summary scores of knowledge and behavior between the control and intervention groups, this study found a modest improvement in fire safety behavior among children whose families received a fire prevention intervention reflecting a change in household fire safety practices. However, there was no significant change in fire safety knowledge. PMID:17018679
"Is there a gun in the home?" Assessing the risks of gun ownership in older adults.
Pinholt, Ellen M; Mitchell, Joshua D; Butler, Jane H; Kumar, Harjinder
2014-06-01
An important ethical and safety concern that geriatricians, primary care providers, and home health professionals need to address is gun ownership by elderly adults. Those aged 65 and older now have the highest rate of gun ownership in America, and they also have a high prevalence of depression and suicide. Dementia can add additional layers of risk. Even older gun owners who are otherwise intellectually intact may benefit from information about gun safety with the increasing numbers of children being cared for by grandparents. Health professionals should ask patients, "Is there a gun in the home?" in the clinic and during home visits. Healthcare professionals must have knowledge and skills to address safe gun ownership in elderly adults. The 5 L's (Locked, Loaded, Little children, feeling Low, Learned owner) will assist professionals in addressing all aspects of safe ownership. © 2014, Copyright the Authors Journal compilation © 2014, The American Geriatrics Society.
[Spanish drivers' beliefs about speed. Speeding is a major issue of road safety].
Montoro González, Luis; Roca Ruiz, Javier; Lucas-Alba, Antonio
2010-11-01
Extending and updating our knowledge concerning drivers' motivational and cognitive processes is of essential importance if we are to apply policies with long-lasting effects. This study presents data from a representative national survey analyzing the Spanish drivers' beliefs about speed, the risks of speeding, the degree of violation of speed-limits and the reasons for speeding. Results indicate that Spanish drivers rate speeding as a serious offence, yet not among the most dangerous ones. All in all, they claim to comply mostly with the speed limits. However, some interesting violation patterns emerge: observance is lower for generic speed limits according to road type (vs. specific limits shown by certain road signs), and particularly in motorways (vs. single carriageways and urban areas). Risk perception and reasons for speeding emerge as the main factors predicting the levels of speed violations reported. Results suggest that any effective intervention strategy should consider such factors, namely the link between speed, road safety, and drivers' specific reasons for speeding.

Transgenic plants expressing insecticidal proteins from the bacterium, Bacillus thuringiensis (Bt), are revolutionizing agriculture. Bt, which had limited use as a foliar insecticide, has become a major insecticide because genes that produce Bt toxins have been engineered into major crops grown on 11.4 million ha worldwide in 2000. Based on the data collected to date, generally these crops have shown positive economic benefits to growers and reduced the use of other insecticides. The potential ecological and human health consequences of Bt plants, including effects on nontarget organisms, food safety, and the development of resistant insect populations, are being compared for Bt plants and alternative insect management strategies. Scientists do not have full knowledge of the risks and benefits of any insect management strategies. Bt plants were deployed with the expectation that the risks would be lower than current or alternative technologies and that the benefits would be greater. Based on the data to date, these expectations seem valid.
Why "improved" water sources are not always safe.

Existing and proposed metrics for household drinking-water services are intended to measure the availability, safety and accessibility of water sources. However, these attributes can be highly variable over time and space and this variation complicates the task of creating and implementing simple and scalable metrics. In this paper, we highlight those factors - especially those that relate to so-called improved water sources - that contribute to variability in water safety but may not be generally recognized as important by non-experts. Problems in the provision of water in adequate quantities and of adequate quality - interrelated problems that are often influenced by human behaviour - may contribute to an increased risk of poor health. Such risk may be masked by global water metrics that indicate that we are on the way to meeting the world's drinking-water needs. Given the complexity of the topic and current knowledge gaps, international metrics for access to drinking water should be interpreted with great caution. We need further targeted research on the health impacts associated with improvements in drinking-water supplies.

Objectives To develop a brief intervention and to assess the feasibility of pharmacy-delivered education on opioid safety and overdose prevention in the emergency department. Methods A convenience sample of patients (n = 102) approached between May and June 2016 at a single community-based suburban emergency department located in the Midwest. Results The intervention included scripted counseling to be delivered in person and 2 educational brochures. The counseling took approximately 5 minutes, and only 2 patients refused the counseling. All the patients were satisfied with the intervention, and 97.4% of them reported that the counseling improved their knowledge of opioid side effects. The majority of patients thought that their own risk of addiction was significantly less than the general public’s risk of addiction when taking opioids. Conclusion This study provides preliminary evidence that student pharmacists or pharmacists are able to deliver opioid safety and overdose education in the emergency department. PMID:28292506
Risk management of biosimilars in oncology: each medicine is a work in progress.
Vulto, Arnold G; Crow, Stacy A
2012-03-01
Drug licensing and drug safety monitoring for standard chemical entities have been established and are routinely used. These have resulted in a solid foundation of knowledge from which confident therapeutic decisions can be made. For many chemical entities, this advanced level of experience is also present for the generic products. The expertise surrounding the development of biosimilar competitor versions is increasing and progress is encouraging. To address the re-engineering and comparability complexities of biosimilars, the European Union imposed a requirement that risk management plans be included in the medications' marketing applications. This paper summarizes and discusses the circumstances complicating the public's view of drug safety, historical incidents during the transition from innovative to competitor products, as well as retrospective assessments of the development and post-marketing experiences thus far with two biosimilars. Through assessing the market entries and post-marketing experiences of biosimilars used in oncology, the healthcare field can better prepare for the next wave of comparator-products: biosimilar monoclonal antibodies.

Toxicology and safety assessment are changing and require new strategies for evaluating risk that are less depending on apical toxicity endpoints in animal models and relying more on knowledge of the mechanism of toxicity. This manuscript describes a number of developments that could contribute to this change and implement this in a stepwise roadmap that can be applied for the evaluation of food and food ingredients. The roadmap was evaluated in four case studies by using literature and existing data. This preliminary evaluation was shown to be useful. However, this experience should be extended by including examples where experimental work needs to be included. To further implement these new insights in toxicology and safety assessment for the area of food and food ingredients, the recommendation is that stakeholders take action in addressing gaps in our knowledge, e.g. with regard to the applicability of the roadmap for mixtures and food matrices. Further development of the threshold of toxicological concern is needed, as well as cooperation with other sectors where similar schemes are under development. Moreover, a more comprehensive evaluation of the roadmap, also including the identification of the need for in vitro experimental work is recommended. Copyright © 2016 ILSI Europe.

Efforts are underway to transform regulatory toxicology and chemical safety assessment from a largely empirical science based on direct observation of apical toxicity outcomes in whole organism toxicity tests to a predictive one in which outcomes and risk are inferred from accumulated mechanistic understanding. The adverse outcome pathway (AOP) framework provides a systematic approach for organizing knowledge that may support such inference. Likewise, computational models of biological systems at various scales provide another means and platform to integrate current biological understanding to facilitate inference and extrapolation. We argue that the systematic organization of knowledge into AOP frameworks can inform and help direct the design and development of computational prediction models that can further enhance the utility of mechanistic and in silico data for chemical safety assessment. This concept was explored as part of a workshop on AOP-Informed Predictive Modeling Approaches for Regulatory Toxicology held September 24-25, 2015. Examples of AOP-informed model development and its application to the assessment of chemicals for skin sensitization and multiple modes of endocrine disruption are provided. The role of problem formulation, not only as a critical phase of risk assessment, but also as guide for both AOP and complementary model development is described. Finally, a proposal for actively engaging the modeling community in AOP-informed computational model development is made. The contents serve as a vision for how AOPs can be leveraged to facilitate development of computational prediction models needed to support the next generation of chemical safety assessment. © The Author 2016.

Guidelines for overcoming hospital managerial challenges: a systematic literature review
Crema, Maria; Verbano, Chiara
2013-01-01
Purpose The need to respond to accreditation institutes’ and patients’ requirements and to align health care results with increased medical knowledge is focusing greater attention on quality in health care. Different tools and techniques have been adopted to measure and manage quality, but clinical errors are still too numerous, suggesting that traditional quality improvement systems are unable to deal appropriately with hospital challenges. The purpose of this paper is to grasp the current tools, practices, and guidelines adopted in health care to improve quality and patient safety and create a base for future research on this young subject. Methods A systematic literature review was carried out. A search of academic databases, including papers that focus not only on lean management, but also on clinical errors and risk reduction, yielded 47 papers. The general characteristics of the selected papers were analyzed, and a content analysis was conducted. Results A variety of managerial techniques, tools, and practices are being adopted in health care, and traditional methodologies have to be integrated with the latest ones in order to reduce errors and ensure high quality and patient safety. As it has been demonstrated, these tools are useful not only for achieving efficiency objectives, but also for providing higher quality and patient safety. Critical indications and guidelines for successful implementation of new health managerial methodologies are provided and synthesized in an operative scheme useful for extending and deepening knowledge of these issues with further studies. Conclusion This research contributes to introducing a new theme in health care literature regarding the development of successful projects with both clinical risk management and health lean management objectives, and should address solutions for improving health care even in the current context of decreasing resources.

As a precaution against acquiring food-borne illnesses, guidelines recommend women avoid some foods during pregnancy. To examine among women receiving antenatal care: (i) level of knowledge and self-reported adherence to guidelines about foods that should be avoided during pregnancy; and (ii) associated socio-demographic characteristics. Women attending a public outpatient clinic who were: pregnant or had recently given birth; 18 years or older; able to complete an English language survey with minimal assistance; and had at least one prior antenatal appointment for their current pregnancy, were asked to complete a cross-sectional survey. In total 223 women (64% consent rate) participated. Knowledge of foods to avoid during pregnancy was poor, with 83% of women incorrectly identifying at least one unsafe food as safe to consume. The average knowledge score for foods to avoid during pregnancy was 7.9 (standard deviation = 3.4; median = 9; interquartile range: 6-11; n = 218) out of a possible score of 12. Having more general practice (GP) visits for antenatal care and fewer tertiary antenatal visits were significantly associated with higher knowledge. Women with a higher number of GP visits and those receiving care in a high-risk clinic were more likely to be adherent to guidelines. The majority of pregnant women have poor knowledge of food avoidance guidelines and continue to consume foods that put them at risk. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Importance Several innovative disease-modifying treatments (DMTs) for relapsing remitting multiple sclerosis (RRMS) have been licensed recently, or are in late-stage development. The molecular targets of several of these DMTs are well defined. All affect at least one of four properties: (1) immune cell trafficking, (2) cell depletion, (3) immune cell function, or (4) cell replication. In contrast to β-interferons and glatiramer acetate, the first generation DMTs, several newer therapies are imbued with safety issues. In addition to efficacy, understanding the relationship between the mechanism of action (MOA) of the DMTs and their safety profile is essential for decision-making in patient care. Objective In this article, we relate safety issues of newer DMTs to their pharmacological characteristics, including molecular targets, MOA, chemical structure, and metabolism. Some newer DMTs also represent repurposing or modifications of previous treatments used in other diseases. Here, we describe how identification and understanding of adverse events (AEs) observed with these established drugs within the same class, provide clues regarding safety and toxicities of newer MS therapeutics. Conclusions and relevance While understanding mechanisms underlying DMT toxicities is incomplete, it is important to further develop this knowledge to minimize risk to patients, and to ensure future therapies have the most advantageous risk-benefit profiles. Recognizing the individual classes of DMTs described here may be beneficial when considering use of such agents sequentially and possibly in combination. PMID:23921521

All nuclear medicine nurses need to have some knowledge and awareness on radiation safety. At present, there is no study to address this issue in Malaysia. The aims of this study were (1) to determine the level of knowledge and awareness on radiation safety among nuclear medicine nurses at Putrajaya Hospital in Malaysia and (2) to assess the effectiveness of a training program provided by the hospital to increase the knowledge and awareness of the nuclear medicine nurses. A total of 27 respondents attending a training program on radiation safety were asked to complete a questionnaire. The questionnaire consists 16 items and were categorized into two main areas, namely general radiation knowledge and radiation safety. Survey data were collected before and after the training and were analyzed using descriptive statistics and paired sample t-test. Respondents were scored out of a total of 16 marks with 8 marks for each area. The findings showed that the range of total scores obtained by the nuclear medicine nurses before and after the training were 6-14 (with a mean score of 11.19) and 13-16 marks (with a mean score of 14.85), respectively. Findings also revealed that the mean score for the area of general radiation knowledge (7.59) was higher than that of the radiation safety (7.26). Currently, the knowledge and awareness on radiation safety among the nuclear medicine nurses are at the moderate level. It is recommended that a national study be conducted to assess and increase the level of knowledge and awareness among all nuclear medicine nurses in Malaysia.

Persons living with AIDS are highly vulnerable to foodborne enteric infections with the potential for substantial morbidity and mortality. Educational materials about foodborne enteric infections intended for this immunocompromised population have not been assessed for their efficacy in improving knowledge or encouraging behavior change. AIDS patients in four healthcare facilities in Chicago, New Orleans, and Puerto Rico were recruited using fliers and word of mouth to healthcare providers. Those who contacted research staff were interviewed to determine food safety knowledge gaps and risky behaviors. A food safety educational comic book that targeted knowledge gaps was created, piloted, and provided to these patients who were instructed to read it and return at least 2 weeks later for a follow-up interview. The overall food safety score was determined by the number of the 26 knowledge/belief/behavior questions from the survey answered correctly. Among 150 patients who participated in both the baseline and follow-up questionnaire, the intervention resulted in a substantial increase in the food safety score (baseline 59%, post-intervention 81%, p<0.001). The intervention produced a significant increase in all the food safety knowledge, belief, and behavior items that comprised the food safety score. Many of these increases were from baseline knowledge below 80 percent to well above 90%. Most (85%) of the patients stated they made a change to their behavior since receiving the educational booklet. This comic book format intervention to educate persons living with AIDS was highly effective. Future studies should examine to what extent long-term behavioral changes result.
Knowledge is power: averting safety-compromising events in the OR.
Catalano, Kathleen

Surgical procedures can be unpredictable, and safety-compromising events can jeopardize patient safety. Perioperative nurses should be watchful for factors that can contribute to safety-compromising events, as well as the errors that can follow, and know how to avert them if possible. Knowledge is power and increased awareness of patient safety issues and the resources that are available to both health care practitioners and consumers can help perioperative nurses ward off patient safety problems before they occur.

In most countries, drivers licensing systems usually include teaching some aspects of using safety equipment (e.g., airbags and seat belts). However, there is now evidence worldwide that such education is inadequate, as indicated by, for example, the overrepresentation of young drivers who do not use seat belts. A randomized controlled study was conducted in Sweden to evaluate the effects of visiting a facility known as a "safety hall" in combination with the mandatory skid training. The results were assessed to determine the effects of the knowledge and attitudes of learner drivers in the following subjects: airbags, securing loads, seat belts, sitting posture, speed, and tires. An experimental group and a control group comprising 658 and 668 learners, respectively, answered identical questionnaires on three different occasions (pretest, posttest 1, and posttest 2). The results show that, for most of the topics considered, knowledge and attitudes in both groups were better at posttest 2 than at the pretest, and in general, the best knowledge and attitudes were found in the experimental group. The combined safety/skid training seems to have had the greatest effect on seat belts and loads. The findings also indicate that the safety halls can be further improved to achieve an even better effect. The use of safety halls has improved the knowledge and attitudes of learner drivers concerning several important areas related to traffic safety. Since knowledge and attitudes are important predictors of behavior, implementing safety halls can be expected to lead to improvements, especially regarding the use of safety belts and securing loads.

To investigate whether novel, non-technical skills training for Bowel Cancer Screening (BCS) endoscopy teams enhanced patient safety knowledge and attitudes. A novel endoscopy team training intervention for BCS teams was developed and evaluated as a pre-post intervention study. Four multi-disciplinary BCS teams constituting BCS endoscopist(s), specialist screening practitioners, endoscopy nurses and administrative staff (A) from English BCS training centres participated. No patients were involved in this study. Expert multidisciplinary faculty delivered a single day's training utilising real clinical examples. Pre and post-course evaluation comprised participants' patient safety awareness, attitudes, and knowledge. Global course evaluations were also collected. Twenty-three participants attended and their patient safety knowledge improved significantly from 43%-55% (P ≤ 0.001) following the training intervention. 12/41 (29%) of the safety attitudes items significantly improved in the areas of perceived patient safety knowledge and awareness. The remaining safety attitude items: perceived influence on patient safety, attitudes towards error management, error management actions and personal views following an error were unchanged following training. Both qualitative and quantitative global course evaluations were positive: 21/23 (91%) participants strongly agreed/agreed that they were satisfied with the course. Qualitative evaluation included mandating such training for endoscopy teams outside BCS and incorporating team training within wider endoscopy training. Limitations of the study include no measure of increased patient safety in clinical practice following training. A novel comprehensive training package addressing patient safety, non-technical skills and adverse event analysis was successful in improving multi-disciplinary teams' knowledge and safety attitudes.

Safety data are continuously evaluated throughout the life cycle of a medical product to accurately assess and characterize the risks associated with the product. The knowledge about a medical product's safety profile continually evolves as safety data accumulate. This paper discusses data sources and analysis considerations for safety signal detection after a medical product is approved for marketing. This manuscript is the second in a series of papers from the American Statistical Association Biopharmaceutical Section Safety Working Group. We share our recommendations for the statistical and graphical methodologies necessary to appropriately analyze, report, and interpret safety outcomes, and we discuss the advantages and disadvantages of safety data obtained from passive postmarketing surveillance systems compared to other sources. Signal detection has traditionally relied on spontaneous reporting databases that have been available worldwide for decades. However, current regulatory guidelines and ease of reporting have increased the size of these databases exponentially over the last few years. With such large databases, data-mining tools using disproportionality analysis and helpful graphics are often used to detect potential signals. Although the data sources have many limitations, analyses of these data have been successful at identifying safety signals postmarketing. Experience analyzing these dynamic data is useful in understanding the potential and limitations of analyses with new data sources such as social media, claims, or electronic medical records data.

OBJECTIVES. This feasibility study examined whether a sun safety curriculum designed for and administered to preschoolers affects their cognition (knowledge, comprehension, application) regarding sun safety. METHODS. Twelve classes of 4- to 5-year-olds were recruited from local preschools and randomly assigned to an intervention group or a control group. The intervention group received an investigator-developed sun safety curriculum; the control group did not. Children in both groups were tested at the beginning of the study about their cognition related to sun safety. They then received posttests 2 and 7 weeks following the pretest. RESULTS. The curriculum had a significant effect on the knowledge (P = .01) and comprehension (P = .006) components of cognition. The application component of cognition was not significantly changed by the curriculum. CONCLUSIONS. A structured curriculum was found to be an efficacious means of enhancing knowledge and comprehension of sun safety in preschool children. At the preoperational developmental stage, however, children may not be able to apply such knowledge and comprehension. PMID:7604917
Survey of current practice in clinical transvaginal ultrasound scanning in the UK
Shaw, Adam; Lees, Christoph
2015-01-01
During transvaginal ultrasound scanning, the fetus and other sensitive tissues are placed close to the transducer. Heating of these tissues occurs by direct conduction from the transducer and by absorption of ultrasound in the tissue. The extent of any heating will depend on the equipment and settings used, the duration of the scan, imaging modes and other aspects of scanning practice. To ensure that scans are performed with minimum risk, staff should have an appropriate knowledge of safety and follow guidelines issued by professional bodies. An online survey aiming to document current practice in transvaginal ultrasound in the UK was created and distributed to individuals performing this type of scanning. The survey posed questions about the respondents, the departments where scans were performed, the equipment used, knowledge of ultrasound safety, scanning practice and the frequency, duration and mode of transvaginal ultrasound scans for gynaecology, obstetrics and fertility applications. In all, 294 responses were obtained, mostly from sonographers (94%). From the analysis of the responses, it was clear that there was a good understanding of the general meaning of thermal and mechanical index and high awareness of guidelines issued by professional bodies. However, 40% of respondents stated that they rarely or never monitor Thermal or Mechanical indices during scanning. Scanning practice was consistent in terms of the duration of scans, scan protocols followed and use of imaging modes. The results highlight the importance of continued ultrasound safety training and promotion of safety guidelines to users. PMID:27433250

Foodborne infection is a result of exposure to complex, dynamic food systems. The efficiency of foodborne infection is driven by ongoing shifts in genetic machinery. Next-generation sequencing technologies can provide high-fidelity data about the genetics of a pathogen. However, food safety surveillance systems do not currently provide similar high-fidelity epidemiological metadata to associate with genetic data. As a consequence, it is rarely possible to transform genetic data into actionable knowledge that can be used to genuinely inform risk assessment or prevent outbreaks. Big data approaches are touted as a revolution in decision support, and pose a potentially attractive method for closing the gap between the fidelity of genetic and epidemiological metadata for food safety surveillance. We therefore developed a simple food chain model to investigate the potential benefits of combining 'big' data sources, including both genetic and high-fidelity epidemiological metadata. Our results suggest that, as for any surveillance system, the collected data must be relevant and characterize the important dynamics of a system if we are to properly understand risk: this suggests the need to carefully consider data curation, rather than the more ambitious claims of big data proponents that unstructured and unrelated data sources can be combined to generate consistent insight. Of interest is that the biggest influencers of foodborne infection risk were contamination load and processing temperature, not genotype. This suggests that understanding food chain dynamics would probably more effectively generate insight into foodborne risk than prescribing the hazard in ever more detail in terms of genotype.

The goal of REACH is the safe use of chemicals. This study examines the efficiency and usefulness of two draft technical guidance notes in the REACH Interim Project 3.2-2 for the development of the chemical safety report and exposure scenarios. A case study was carried out for a paint system for protection of structural steel. The focuses of the study were risk assessment of preparations based on Derived No Effect Level (DNEL) and Predicted No Effect Concentrations (PNEC) and on effective and accurate communication in the supply chain. Exposure scenarios and generic descriptions of uses, risk management measures, and exposure determinants were developed. The study showed that communication formats, software tools, and guidelines for chemical risk assessment need further adjustment to preparations and real-life situations. Web platforms may simplify such communication. The downstream formulator needs basic substance data from the substance manufacturer during the pre-registration phase to develop exposure scenarios for preparations. Default values need to be communicated in the supply chain because these were critical for the derivation of applicable risk management demands. The current guidelines which rely on the available toxicological knowledge are insufficient to advise downstream users on how to develop exposure scenarios for preparations.
Awareness and knowledge of methylmercury in fish in the United States

Lando, Amy M., E-mail: amy.lando@fda.hhs.gov; Zhang, Yuanting
In the 1970s several states in the Great Lakes region became concerned about mercury contamination in lakes and rivers and were the first to issue local fish consumption advisories. In 2001, the Food and Drug Administration (FDA) advised pregnant women, nursing mothers, young children, and women who may become pregnant not to consume shark, swordfish, king mackerel, and tilefish and recommended that these women not exceed 12 ounces of other fish per week. In 2004, FDA reissued this advice jointly with the U.S. Environmental Protection Agency (EPA) and modified it slightly to provide information about consumption of canned tuna andmore » more details about consumption of recreationally caught fish. Though several studies have examined consumers' awareness of the joint FDA and EPA advisory as well as different state advisories, few used representative data. We examined the changes in awareness and knowledge of mercury as a problem in fish using the pooled nationally representative 2001 and 2006 Food Safety Surveys (FSS) with sample sizes of 4482 in 2001 and 2275 in 2006. Our results indicated an increase in consumers' awareness of mercury as a problem in fish (69% in 2001 to 80% in 2006, p<.001). In our regression models, we found that in both years, parents having children less than 5 years of age were more aware of mercury in fish and knowledgeable about the information contained in the national advisories about mercury in fish (p<.01) than other adults. In both 2001 and 2006, women of childbearing age (aged 18-45) were less aware and knowledgeable about this information than other women. However, women of all age groups had larger gains in awareness and knowledge than their male counterparts during this time. Participants' race, education, income, region, fish preparation experiences, having a foodborne illness in the past year, and risk perceptions about the safety of food were significant predictors of their awareness and knowledge. - Research highlights: {yields} We examined changes in awareness and knowledge of mercury as a problem in fish. {yields} Data are from the 2001 and 2006 Food Safety Surveys (FSS). {yields} Consumers' awareness of mercury as a problem in fish increased from 2001 to 2006. {yields} Demographics were significant predictors of awareness and knowledge.« less

Textile dye workers are subject to occupational hazards on a daily basis due to exposure to precarious conditions in the workplace. This study aimed to assess the knowledge, attitude and safety practices and its determinants among textile dye workers in Sokoto metropolis, Nigeria. This is a descriptive cross-sectional study conducted among 200 textile dye workers and the respondents were selected by multi stage sampling technique. Data was collected using an interviewer administered questionnaire. Data was processed using SPSS IBM version 20 and analyzed using descriptive and inferential statistics. Majority of the respondents (74.0%) had good knowledge of workplace hazards; (81.0%) had positive attitude and only 20% observed all the safety practices. Formal education (P=0.047); working less than 5 days a week (P=0.001) and permanent employment (P=0.013) were found to be determinants of respondents' knowledge and attitude towards workplace hazards. Although the respondents had good knowledge and positive attitude, their lack of observance of safety practices brings to fore the need for direct safety instruction and training and retraining of textile dye workers on workplace hazards and safety practices.

Recently, the patient's role in preventing adverse events has been emphasized. Patients who are more knowledgeable about safety issues are more likely to engage in safety initiatives. Therefore, nurses need to develop techniques and tools that increase patients' knowledge in preventing adverse events. For this reason, an educational smartphone application for patient safety called "Safe Patients" was developed through an iterative process involving a literature review, expert consultations, and pilot testing of the application. To determine the effect of "Safe Patients," it was implemented for patients in surgical units in a tertiary hospital in South Korea. The change in patients' knowledge about patient safety was measured using seven true/false questions developed in this study. A one-group pretest and posttest design was used, and a total of 123 of 190 possible participants were tested. The percentage of correct answers significantly increased from 64.5% to 75.8% (P < .001) after implementation of the "Safe Patients" application. This study demonstrated that the application "Safe Patients" could effectively improve patients' knowledge of safety issues. This will ultimately empower patients to engage in safe practices and prevent adverse events related to surgery.

To report the impact of transformational leadership on two dimensions of nurses' safety performance (i.e. safety compliance and safety participation) and to study the mediating role of knowledge-related job characteristics in this relationship. Safety performance refers to the behaviours that employees exhibit to adhere to safety guidelines and to promote health and safety at their workplace. Nurses' safety performance is a major challenge for healthcare settings, urging the need to identify the key determinants and psychological mechanisms that influence it. A cross-sectional survey study. The study was carried out in September 2010 in a large Belgian hospital. We used self-administered questionnaires; 152 nurses participated. The hypotheses were tested using hierarchical regression analyses. In line with our first hypothesis, the results show that transformational leadership exerted a significant positive impact on both dimensions of nurses' safety performance. This positive relation was mediated by knowledge-related job characteristics, supporting our second hypothesis. Head nurses' transformational leadership can enhance nurses' compliance with and participation in safety. Furthermore, transformational head nurses are able to influence the perception that their nurses have about the kind and amount of knowledge in their job, which can also lead to increases in both dimensions of nurses' safety performance. This study therefore demonstrates the key impact that transformational head nurses have, both directly and indirectly, on the safety performance of their nurses. © 2013 John Wiley & Sons Ltd.

Objectives Examine changes in health beliefs, pesticide safety knowledge, and biomarkers of pesticide exposure in indigenous farmworker who received enhanced pesticide safety training compared to those receiving the standard training. Methods Farmworkers in Oregon were randomly assigned to either a promotores pesticide safety training program or a standard video-based training. Spot urine samples were analyzed for dialkylphosphate (DAP) urinary metabolites. Pre/post intervention questionnaires were used to measure pesticide safety knowledge, health beliefs and work practices. Results Baseline to follow-up improvements in total pesticide knowledge scores were higher in the promotor group compared to the video. Pairwise differences in mean concentrations of DAP metabolite levels showed declines from baseline to follow-up for both intervention groups. Conclusions Results showed reductions in pesticide exposure in indigenous-language speaking farmworkers who receive enhanced pesticide safety training. PMID:24064776

The National Aeronautics and Space Administration (NASA) Safety & Mission Assurance (S&MA) directorate at the Johnson Space Center (JSC) has applied its knowledge and experience with Probabilistic Risk Assessment (PRA) to projects in industries ranging from spacecraft to nuclear power plants. PRA is a comprehensive and structured process for analyzing risk in complex engineered systems and/or processes. The PRA process enables the user to identify potential risk contributors such as, hardware and software failure, human error, and external events. Recent developments in the oil and gas industry have presented opportunities for NASA to lend their PRA expertise to both ongoing and developmental projects within the industry. This paper provides an overview of the PRA process and demonstrates how this process was applied in estimating the probability that a Mobile Offshore Drilling Unit (MODU) operating in the Gulf of Mexico and equipped with a generically configured Dynamic Positioning System (DPS) loses location and needs to initiate an emergency disconnect. The PRA described in this paper is intended to be generic such that the vessel meets the general requirements of an International Maritime Organization (IMO) Maritime Safety Committee (MSC)/Circ. 645 Class 3 dynamically positioned vessel. The results of this analysis are not intended to be applied to any specific drilling vessel, although provisions were made to allow the analysis to be configured to a specific vessel if required.

We conducted a qualitative study of male sex work in St. Petersburg Russia with a focus on social vulnerabilities, HIV risk perception, and HIV-related behaviours. In-depth interviews were conducted with individuals knowledgeable about male sex work through their profession (n=8) and with male sex workers themselves (n=12). Male sex work involves a variety of exchanges including expensive vacations, negotiated monetary amounts, or simply access to food. Methods to find clients included the Internet, social venues (e.g. gay clubs and bars), and public places (e.g. parks). Use of the Internet greatly facilitated male sex work in a variety of ways. It was used by both individuals and agencies to find clients, and appeared to be increasing. Men often reported not being professionally connected to other male sex workers and limited disclosure about their work. Many were aware of the work-related risks to personal safety including violence and robbery by clients. Perceived risk for HIV was mostly abstract, and several exceptions to condom use with clients were noted. Alcohol use was reported as moderate but consumed frequently in association with work. These data suggest that the most salient risks for male sex workers include professional isolation, threats to personal safety, limited perceived HIV risk, and sub-optimal levels of condom use.

Studies measuring the effectiveness of risk minimization measures (RMMs) submitted by pharmaceutical companies to the European Medicines Agency are part of the post-authorization regulatory requirements and represent an important source of data covering a range of medicinal products and safety-related issues. Their objectives, design, and the associated regulatory outcomes were reviewed, and conclusions were drawn that may support future progress in risk minimization evaluation. Information was obtained from risk management plans, study protocols, clinical study reports, and assessment reports of 157 medicinal products authorized for cardiovascular, endocrinology, and metabolic indications. We selected observational studies measuring, as outcomes of interest, the relationship between the RMMs in place and (1) implementation measures, such as clinical knowledge or physicians` compliance to recommendations contained in the RMMs; and (2) occurrence or reduced severity of the adverse drug reactions for which the RMMs were required. Of 59 eligible studies (24 completed, 35 ongoing), 44 assessed implementation measures, whereas only 15 assessed safety outcomes (1 study as a single endpoint and 14 studies with other endpoints). Fifty-one studies used non-experimental designs and 25 studies employed electronic healthcare databases for analysis. Of the 24 completed studies, 17 were considered satisfactory and supported immediate regulatory decision making, 6 were considered inconclusive and required new evaluations, and 1 was terminated early because new safety restrictions were required, thereby necessitating a new evaluation. Compliance with agreed deadlines was considered acceptable in 21 of 24 completed studies; the average time for a submission was 37 months (standard deviation ± 17), with differences observed by type of data source employed. Three important gaps in the evaluation plans of RMMs were identified: lack of early feedback on implementation, limited evaluation of safety outcomes, and inability to provide information on the effectiveness from an integrated measurement of different elements of a set of risk minimization tools. More robust evidence is needed to advance regulatory science and support more rapid adjustment of risk minimization strategies as needed.

Enhancing competency in patient safety at entry to practice requires introduction and integration of patient safety into health professional education. As efforts to include patient safety in health professional education increase, it is important to capture new health professionals' perspectives of their own patient safety competence at entry to practice. Existing instruments to measure patient safety knowledge, skills and attitudes have been developed largely to examine the impact of specific patient safety curricular initiatives and the psychometric analyses of the instruments used thus far have been exploratory in nature. Confirmatory factor analytic approaches are used to extensively test the Health Professional Education in Patient Safety Survey (H-PEPSS), a newly designed survey rooted in a patient safety competency framework and designed to measure health professionals' self-reported patient safety competence around the time of entry to practice. The H-PEPSS focuses primarily on the socio-cultural aspects of patient safety including culture, teamwork, communication, managing risk and understanding human factors. Results support a parsimonious six-factor measurement model of health professionals' perceptions of patient safety competency. These results support the validity of a reduced version of the H-PEPSS and suggest it can be appropriately used at or near training completion with a variety of health professional groups. Given increased demands for patient safety competency among health professionals at entry to practice and slow, but emerging changes in health professional education, ongoing research to understand the extent of patient safety competency among health professionals around the time of entry to practice will be important.

Epistemic Questions and Answers for Software System Safety

Holloway, C. M.; Johnson, Chris W.
2010-01-01
System safety is primarily concerned with epistemic questions, that is, questions concerning knowledge and the degree of confidence that can be placed in that knowledge. For systems with which human experience is long, such as roads, bridges, and mechanical devices, knowledge about what is required to make the systems safe is deep and detailed. High confidence can be placed in the validity of that knowledge. For other systems, however, with which human experience is comparatively short, such as those that rely in part or in whole on software, knowledge about what is required to ensure safety tends to be shallow and general. The confidence that can be placed in the validity of that knowledge is consequently low. In a previous paper, we enumerated a collection of foundational epistemic questions concerning software system safety. In this paper, we review and refine the questions, discuss some difficulties that attend to answering the questions today, and speculate on possible research to improve the situation.

The handling of laboratory, imaging and other test results in UK general practice is a high-volume organisational routine that is both complex and high risk. Previous research in this area has focused on errors and harm, but a complementary approach is to better understand how safety is achieved in everyday practice. This paper ethnographically examines the role of informal dimensions of test results handling routines in the achievement of safety in UK general practice and how these findings can best be developed for wider application by policymakers and practitioners. Non-participant observation was conducted of high-volume organisational routines across eight UK general practices with diverse organisational characteristics. Sixty-two semi-structured interviews were also conducted with the key practice staff alongside the analysis of relevant documents. While formal results handling routines were described similarly across the eight study practices, the everyday structure of how the routine should be enacted in practice was informally understood. Results handling safety took a range of local forms depending on how different aspects of safety were prioritised, with practices varying in terms of how they balanced thoroughness (i.e. ensuring the high-quality management of results by the most appropriate clinician) and efficiency (i.e. timely management of results) depending on a range of factors (e.g. practice history, team composition). Each approach adopted created its own potential risks, with demands for thoroughness reducing productivity and demands for efficiency reducing handling quality. Irrespective of the practice-level approach adopted, staff also regularly varied what they did for individual patients depending on the specific context (e.g. type of result, patient circumstances). General practices variably prioritised a legitimate range of results handling safety processes and outcomes, each with differing strengths and trade-offs. Future safety improvement interventions should focus on how to maximise practice-level knowledge and understanding of the range of context-specific approaches available and the safeties and risks inherent in each within the context of wider complex system conditions and interactions. This in turn has the potential to inform new kinds of proactive, contextually appropriate approaches to intervention development and implementation focusing on the enhanced deliberation of the safety of existing high-volume routines.
Benchmarking Global Food Safety Performances: The Era of Risk Intelligence.
Valleé, Jean-Charles Le; Charlebois, Sylvain
2015-10-01
Food safety data segmentation and limitations hamper the world's ability to select, build up, monitor, and evaluate food safety performance. Currently, there is no metric that captures the entire food safety system, and performance data are not collected strategically on a global scale. Therefore, food safety benchmarking is essential not only to help monitor ongoing performance but also to inform continued food safety system design, adoption, and implementation toward more efficient and effective food safety preparedness, responsiveness, and accountability. This comparative study identifies and evaluates common elements among global food safety systems. It provides an overall world ranking of food safety performance for 17 Organisation for Economic Co-Operation and Development (OECD) countries, illustrated by 10 indicators organized across three food safety risk governance domains: risk assessment (chemical risks, microbial risks, and national reporting on food consumption), risk management (national food safety capacities, food recalls, food traceability, and radionuclides standards), and risk communication (allergenic risks, labeling, and public trust). Results show all countries have very high food safety standards, but Canada and Ireland, followed by France, earned excellent grades relative to their peers. However, any subsequent global ranking study should consider the development of survey instruments to gather adequate and comparable national evidence on food safety.

Tourism safety is gradually gaining more attention due to the rapid development of the tourism industry in China. Changbai Mountain is one of the most famous mountainous scenic areas in Northeast Asia. Assessment on Changbai Mountain scenic area’s tourism safety risk could do a favor in detecting influence factor of tourism safety risk and classifying tourism safety risk rank, thereby reducing and preventing associated tourism safety risks. This paper uses the Changbai Mountain scenic area as the study subject. By the means of experts scoring and analytic hierarchy process on quantified relevant evaluation indicator, the grid GIS method is used to vectorize the relevant data within a 1000m grid. It respectively analyzes main indicators associated tourism safety risk in Changbai Mountain scenic area, including hazard, exposure, vulnerability and ability to prevent and mitigate disasters. The integrated tourism safety risk model is used to comprehensively evaluate tourism safety risk in Changbai Mountain scenic area.

A suitable sun safety educational program could help the public avoid sun exposure-induced skin damage. The objective of this study was to assess the impact of a sun safety program on volunteers in outdoor venues and explore the most effective sun safety education method in China. An intervention program was implemented to raise knowledge and behavior regarding sun exposure among volunteers in the outdoor competition venues in Beijing, China. Five intervention methods were used, including class education, free sunscreen samples, pamphlets, posters, and newsletters. The self-administered multiple-choice questionnaires were administered before and after the intervention. Two hundred and eighty-five subjects were enrolled, including 107 males (37.5%) and 178 females (62.5%). The intervention group showed improvement in sun safety knowledge and behavior. Other improvements were achieved in the field of sun safety awareness and intended behavior, with most of the items achieving no statistically significant differences. Subgroup A (multi-component interventions, including class education, free sunscreen samples, and written materials) achieved better results than subgroup B (written materials only) to improve sun safety knowledge and awareness. Sun safety education could improve volunteer 's sun safety knowledge and behavior in the outdoor venues in China. Multi-component interventions proved to be the most effective sun safety education method. © 2011 John Wiley & Sons A/S.
Regulatory Agencies and Food Safety
Chapman, R. A.; Morrison, A. B.

Prior to Confederation, food control legislation in Canada consisted of only a few simple laws governing the quality, grading, packing and inspection of certain staple foods. The Inland Revenue Act of 1875 provided the first real control in Canada over adulteration of liquor, foods and drugs. Since then, food legislation has evolved in scope and complexity as the industries involved have developed, as consumers have become better informed, and as scientific advances have provided a sound basis for regulations. Present regulations under the Food and Drugs Act are intended to give consumers broad protection against health hazards and fraud in the production, manufacture, labelling, packaging, advertising, and sale of foods. This principle is well illustrated by present requirements for the control of pesticide residues, chemical additives, and the addition of vitamins to foods. In today's era of rapid technological change, application of current scientific knowledge to the food industry obviously involves the possibility of hazards to health. Regulatory agencies with responsibility for food safety must, therefore, fully utilize scientific knowledge in order to reduce the risks involved to a minimum. PMID:5905951

Anticonvulsants require special consideration particularly at the interface from hospital to ambulatory care. Observational study for 6 months with prospectively enrolled consecutive patients in a neuropediatric ward of a university hospital (age 0-<18 years) with long-term therapy of at least one anticonvulsant. Assessment of outpatient prescriptions after discharge. Parent interviews for emergency treatment for acute seizures and safety precautions. We identified changes of the brand in 19/82 (23%) patients caused by hospital's discharge letters (4/82; 5%) or in ambulatory care (15/82; 18%). In 37/76 (49%) of patients who were deemed to require rescue medication, no recommendation for such a medication was included in the discharge letters. 17/76 (22%) of the respective parents stated that they had no immediate access to rescue medication. Safety precautions were applicable in 44 epilepsy patients. We identified knowledge deficits in 27/44 (61%) of parents. Switching of brands after discharge was frequent. In the discharge letters, rescue medications were insufficiently recommended. Additionally, parents frequently displayed knowledge deficits in risk management. © Georg Thieme Verlag KG Stuttgart · New York.
Two Cultures in Modern Science and Technology: For Safety and Validity Does Medicine Have to Update?
Becker, Robert E
2016-01-11
Two different scientific cultures go unreconciled in modern medicine. Each culture accepts that scientific knowledge and technologies are vulnerable to and easily invalidated by methods and conditions of acquisition, interpretation, and application. How these vulnerabilities are addressed separates the 2 cultures and potentially explains medicine's difficulties eradicating errors. A traditional culture, dominant in medicine, leaves error control in the hands of individual and group investigators and practitioners. A competing modern scientific culture accepts errors as inevitable, pernicious, and pervasive sources of adverse events throughout medical research and patient care too malignant for individuals or groups to control. Error risks to the validity of scientific knowledge and safety in patient care require systemwide programming able to support a culture in medicine grounded in tested, continually updated, widely promulgated, and uniformly implemented standards of practice for research and patient care. Experiences from successes in other sciences and industries strongly support the need for leadership from the Institute of Medicine's recommended Center for Patient Safely within the Federal Executive branch of government.

Knowledge of drugs safety collected during the pre-marketing phase is inevitably limited because the randomized clinical trials (RCTs) are rarely designed to evaluate safety. The small and selective groups of enrolled individuals and the limited duration of trials may hamper the ability to characterize fully the safety profiles of drugs. Additionally, information about rare adverse drug reactions (ADRs) in special groups is often incomplete or not available for most of the drugs commonly used in the daily clinical practice. In the paediatric setting several highimpact safety issues have emerged. Hence, in recent years, there has been a call for improved post-marketing pharmacoepidemiological studies, in which cohorts of patients are monitored for sufficient time in order to determine the precise risk-benefit ratio. In this review, we discuss the current available strategies enhancing the post-marketing monitoring activities of the drugs in the paediatric setting and define criteria whereby they can provide valuable information to improve the management of therapy in daily clinical practice including both safety and efficacy aspects. The strategies we cover include the signal detection using international pharmacovigilance and/or healthcare databases, the promotion of active surveillance initiatives which can generate complete, informative data sets for the signal detection and systematic review/meta-analysis. Together, these methods provide a comprehensive picture of causality and risk improving the management of therapy in a paediatric setting and they should be considered as a unique tool to be integrated with post-marketing activities.

This study was designed to evaluate the knowledge, attitude, and practice of some commercial motorcyclists in Nigeria in the use of crash helmet and other cycling safety measures. At randomly selected commercial motorcycle parks from two South Western Nigerian locations (Lagos and Ile-Ife), we obtained verbal consent from commercial motorcyclists (randomly selected) and thereafter administered structured questionnaires to consenting motorcyclists. The questionnaire sought to know the respondents' biodata (age, gender, and educational attainment inclusive), cycling background, and experience (trainer, duration of training and cycling, and history of crashes). Furthermore, risk factors and practices like alcoholism, maintenance history of the motorcycle, maximum number of pillion passengers carried, and use of crash helmet were elicited. Respondents' knowledge of available safety measures was also investigated. Data was entered into an IBM compatible computer and analyzed using the SPSS 11.0 statistical software. Statistical significance was inferred at p value<0.05. There were 224 male respondents aged 15-58 years. Their peak age was 25-29 years and mean 35.1+/-8.9 years; 8.4% had no formal education; 10.3% received formal training but the majority were either trained by self (35.5%) or an acquaintance (34.6%).

Introduction Persons living with AIDS are highly vulnerable to foodborne enteric infections with the potential for substantial morbidity and mortality. Educational materials about foodborne enteric infections intended for this immunocompromised population have not been assessed for their efficacy in improving knowledge or encouraging behavior change. Methods/Results AIDS patients in four healthcare facilities in Chicago, New Orleans, and Puerto Rico were recruited using fliers and word of mouth to healthcare providers. Those who contacted research staff were interviewed to determine food safety knowledge gaps and risky behaviors. A food safety educational comic book that targeted knowledge gaps was created, piloted, and provided to these patients who were instructed to read it and return at least 2 weeks later for a follow-up interview. The overall food safety score was determined by the number of the 26 knowledge/belief/behavior questions from the survey answered correctly. Among 150 patients who participated in both the baseline and follow-up questionnaire, the intervention resulted in a substantial increase in the food safety score (baseline 59%, post-intervention 81%, p<0.001). The intervention produced a significant increase in all the food safety knowledge, belief, and behavior items that comprised the food safety score. Many of these increases were from baseline knowledge below 80 percent to well above 90%. Most (85%) of the patients stated they made a change to their behavior since receiving the educational booklet. Conclusion This comic book format intervention to educate persons living with AIDS was highly effective. Future studies should examine to what extent long-term behavioral changes result.

Space radiation presents major challenges to astronauts on the International Space Station and for future missions to the Earth s moon or Mars. Methods used to project risks on Earth need to be modified because of the large uncertainties in projecting cancer risks from space radiation, and thus impact safety factors. We describe NASA s unique approach to radiation safety that applies uncertainty based criteria within the occupational health program for astronauts: The two terrestrial criteria of a point estimate of maximum acceptable level of risk and application of the principle of As Low As Reasonably Achievable (ALARA) are supplemented by a third requirement that protects against risk projection uncertainties using the upper 95% confidence level (CL) in the radiation cancer projection model. NASA s acceptable level of risk for ISS and their new lunar program have been set at the point-estimate of a 3-percent risk of exposure induced death (REID). Tissue-averaged organ dose-equivalents are combined with age at exposure and gender-dependent risk coefficients to project the cumulative occupational radiation risks incurred by astronauts. The 95% CL criteria in practice is a stronger criterion than ALARA, but not an absolute cut-off as is applied to a point projection of a 3% REID. We describe the most recent astronaut dose limits, and present a historical review of astronaut organ doses estimates from the Mercury through the current ISS program, and future projections for lunar and Mars missions. NASA s 95% CL criteria is linked to a vibrant ground based radiobiology program investigating the radiobiology of high-energy protons and heavy ions. The near-term goal of research is new knowledge leading to the reduction of uncertainties in projection models. Risk projections involve a product of many biological and physical factors, each of which has a differential range of uncertainty due to lack of data and knowledge. The current model for projecting space radiation cancer risk relies on the three assumptions of linearity, additivity, and scaling along with the use of population averages. We describe uncertainty estimates for this model, and new experimental data that sheds light on the accuracy of the underlying assumptions. These methods make it possible to express risk management objectives in terms of quantitative metrics, i.e., the number of days in space without exceeding a given risk level within well defined confidence limits. The resulting methodology is applied to several human space exploration mission scenarios including lunar station, deep space outpost, and a Mars mission. Factors that dominate risk projection uncertainties and application of this approach to assess candidate mitigation approaches are described.

Bearing in mind the adverse health effects of exposure to ultraviolet (UV) radiation in solarium, especially the risk of carcinogenesis, there is a need to adopt legal regulations by relevant Polish authorities. They should set out the principles for indoor tanning studios operation, supervision and service of the technical parameters of tanning devices and training programs to provide the staff with professional knowledge and other aspects of safety in these facilities. The mechanism of the harmful effects of ultraviolet radiation on the human body, scale of overexposure, resulting from excessive sunbathing are described. Methods for estimating UV exposure and possible actions aimed at reducing the overexposure and preventing from cancer development caused by UV are also presented in this paper.
