Development of an interprofessional task-based learning program in the field of occupational health: a content validity study

ObjectiveOne of the duties of the educational system is to provide situations in which students learn the tasks corresponding to their future careers in an interprofessional team. This study was designed to develop an interprofessional task-based training program.MethodsThis was a curriculum development study conducted by content validity methodology in two stages: 1) ‘framework development’ which resulted in the creation of the framework items; and 2) ‘evaluation of the framework’ (judgment and quantification). The first stage consisted of task identification, generation of sub-tasks, and assimilation of items into a usable format. The second stage consisted of the judgment –quantification of the content validity of items and the framework. After that, the framework of the tasks of the occupational health team was finalized in the expert panel. After explaining the tasks, a matrix for task-expected roles in the occupational health team and a matrix for task-required skills to perform each task were developed. The next step determined the appropriate teaching and assessment methods for each task. Finally, an expert panel reviewed and approved the components of the interprofessional task-based training program.ResultsIntegrating the interprofessional education strategy with task-based learning was considered innovative in occupational health team training. In the development stage, 48 items were extracted, and then 35 tasks were generated in the step of identification of tasks. In the second step, 174 sub-tasks were developed. The tasks and sub-tasks were categorized into seven areas. After the stage of evaluation of the framework, 33 tasks were categorized into seven main areas, including "assessment and identification of workplace hazards" (n = 10), "control of occupational hazards" (n = 4), "determining the appropriate job position for each person" (n = 3), "occupational health examinations" (n = 6), "management of occupational/work-related diseases" (n = 5), "inter-organizational and inter-disciplinary relations, and legal judgment" (n = 3) and "education and scholarship in occupational health services" (n = 2).ConclusionThe results of the present study can be used in developing the use of the interprofessional strategy and task-based training as two appropriate strategies for the purposeful development of learners' abilities in the fields involved in providing occupational health services in their future careers.

Cumulative noise exposure and the risk of high-frequency hearing loss relationships

Objective: To explore the dose-response relationship between cumulative noise exposure and high-frequency hearing loss, and further to provide a basis for the control of occupational hazards of noise. Methods: A Meta-analysis of dose-response relationships was performed on the data of eligible literatures published in China from January 2000.1 to December 2019.12. Results: The initial combined Odds Ratio (OR) and its 95%CI in the Meta-analysis were 1.10 (1.08-1.12) . As the Begg's funnel plot and Egger's test indicated publication bias (t=5.97, P<0.01) , the Trim-and-Fill Method was used for OR value adjustment. The adjusted-OR was 1.09 (1.07-1.12) ; sensitivity analysis showed that the results of this Meta-analysis have high stability; subgroup analysis indicated that the ORs of the steady-state noise group and the non-steady-state noise group were 1.10 (1.08-1.12) and 1.14 (1.07-1.21) , the ORs of the old standard group and the new standard group were 1.10 (1.08-1.12) and 1.11 (1.00-1.24) , respectively. The nonlinear dose-response relationship curve demonstrated that the risk of high-frequency hearing loss increases rapidly after CNE reaches 95 dB (A) ·years. Conclusion: There is a definite dose-response relationship between CNE and high-frequency hearing loss, which can be used to predict the risk of high-frequency hearing loss in noisy workers.

Required and Voluntary Occupational Use of Hazard Controls for COVID-19 Prevention in Non-Health Care Workplaces - United States, June 2020.

Certain hazard controls, including physical barriers, cloth face masks, and other personal protective equipment (PPE), are recommended to reduce coronavirus 2019 (COVID-19) transmission in the workplace (1). Evaluation of occupational hazard control use for COVID-19 prevention can identify inadequately protected workers and opportunities to improve use. CDC's National Institute for Occupational Safety and Health used data from the June 2020 SummerStyles survey to characterize required and voluntary use of COVID-19-related occupational hazard controls among U.S. non-health care workers. A survey-weighted regression model was used to estimate the association between employer provision of hazard controls and voluntary use, and stratum-specific adjusted risk differences (aRDs) among workers reporting household incomes <250% and ≥250% of national poverty thresholds were estimated to assess effect modification by income. Approximately one half (45.6%; 95% confidence interval [CI]=41.0%-50.3%) of non-health care workers reported use of hazard controls in the workplace, 55.5% (95% CI = 48.8%-62.2%) of whom reported employer requirements to use them. After adjustment for occupational group and proximity to others at work, voluntary use was approximately double, or 22.3 absolute percentage points higher, among workers who were provided hazard controls than among those who were not. This effect was more apparent among lower-income (aRD=31.0%) than among higher-income workers (aRD=16.3%). Employers can help protect workers from COVID-19 by requiring and encouraging use of occupational hazard controls and providing hazard controls to employees (1).

Analysis of the influencing factors of serum bilirubin in workers exposed to occupational hazards factors in a urban area

Objective: To investigate the effect of exposure to occupational hazard factors on serum bilirubin in workers. Methods: In April 2019, using cluster sampling method 5 433 workers exposed to occupational hazard factors from July 2017 to March 2019 were screened out by questionnaire and laboratory test, the date of serum bilirubin were used by the logistic regression analysis of single factor card test and wilcoxon band symbol rank and test. Results: The bilirubin decreases with age, is higher in male than in female, the han is higher than the uygur, and the unmarried workers is higher than the married one, there was significant difference in the levels of bilirubin between different genders, ages, ethnic groups and marriages (P<0.01) . There were statistically significant differences in bilirubin among the occupational hazard factors (P<0.01) , the bilirubin level is highest in the exposure to physical factors, followed by chemical factors and dust. The multivariate logistic regression analysis showed that the dust was the main factor affecting bilirubin (OR(dusr/TBIL)=2.080, 95%CI: 1.542~2.807, P<0.01) . Abnormal alanine aminotransferase (ALT) and alanine aminotransferase (AST) are consistent with elevated bilirubin. Conclusion: Exposure to occupational hazard factors may lead to elevated serum bilirubin and abnormal liver function transaminase, the prevention and control of occupational hazards and cccupational health monitoring should be strengthened.

Using the experience of industrilized countries for reference to promote the prevention and control of occupational stress from research to practice

Occupational stress is one of the major occupational health problems in industrialized countries. In Europe, the United States, Japan, and other countries, occupational stress has been included in the prevention and control of occupational hazards in the workplace. This problem has also become a major risk factor affecting the physical and mental health of the working population in China. Over the last three decades, China had carried out a lot of research on occupational stress and made significant progress, but there is still a big gap between China and industrialized countries in terms of theoretical research on occupational stress, development of measurement tools, research topics and methods, formulation of regulations and standards, and practice of prevention and control. Articles in this key issue report the research on the core scale of occupational stress measurement for the Chinese working population, the scale scoring norm of manufacturing and medical personnel, the research on the relationship between positive psychology variables, and occupational stress and its role in the relationship between occupational stress and health outcomes.

Examining relationship between occupational acid exposure and oral health in workplace

BackgroundAcid mist can suspend in the air and enter the body via skin contact, the respiratory tract, or even oral intake, which pose various health hazards. Previous studies have shown that occupational exposure to acid mist or acidic solutions is a major risk factor for oral diseases. However, the findings are inconsistent and do not consider individual factors and lifestyles that may cause the same oral diseases. Therefore, we conducted a comprehensive oral health survey and collected detail information to confirm the effect of acidic solution exposure on worker’s oral health.MethodsFrom 4 acidic solution factories, a total of 309 subjects (157 in control and 152 in exposed group) was enrolled. All participants competed oral examinations and self-report questionnaire, including the decayed, missing, and filled teeth (DMFT) index, community periodontal index (CPI), loss of attachment (LA) index, and tooth erosion. Multivariate logistic regression analysis was used to determine the association between the acidic solution exposure and oral health.ResultsThe results showed that acid exposure was correlated with soft oral tissue injury rather than hard oral tissue in our survey. In the multivariate model (adjusted for sex, age, worked years, education level, mouthwash use, dental floss use, tooth brushing, mask use, smoking, drinking, chewing areca and dietary habits with acidic foods), significant relationships of acid exposure with LA score were observed (OR = 2.32, 95% CI 1.03–5.26). However, the presence of acid exposure was not significantly associated with tooth erosion, DMFT, and CPITN.ConclusionOur study highlighted that occupational acid exposure was an independent risk factor for periodontal health, especially LA. It is important to strengthen occupational hazard control, educate workers on oral disease and related factors, and raise the awareness of oral hygiene.

The study designs a comprehensive evaluation system for the prevention and control of occupational hazards, calculates its weight coefficient, and provides a potential strategic and effective tool for the scientific evaluation of occupational hazards in the iron and steel enterprises. The system was established through induction and analysis of relevant literature, personal interview, theoretical analysis, Delphi expert consultation, and special group discussions. Using an improved analytical hierarchy process fuzzy comprehensive evaluation model and on the basis of the improved Delphi expert investigation, the weight of the operability comprehensive evaluation index system is constructed. A three-level index system is established on the basis of harmful factors of occupational activities, health status of employees, protection facilities of occupational hazards, occupational health management, and so on. The index system structure is 4-20-95, and the weight coefficients of the four dimensions are 0.2516, 0.2428, 0.2550, and 0.2506. The recovery rate of the questionnaire was 82.5%, 100.0%, and 100.0%. The effective rates were 75.0%, 100.0%, and 100.0%. Conversely, the expert authority coefficients of the four dimensions are 0.875, 0.769, 0.832 and 0.800. Results show that the consistency factors of the four dimensions are statistically significant. Cronbach’s α coefficient, standardized Cronbach’s α coefficient, and split-half reliability of the comprehensive evaluation index system are 0.959, 0.950, and 0.810, respectively. After factor analysis, four common factors were extracted on the basis of expert opinions, and the cumulative variance was 63.1%. The comprehensive evaluation system for the prevention and control of occupational hazards in the iron and steel enterprises proposed by the study is relatively complete and reasonable.

An analysis of assessment results of prevention and control of occupational hazards in a city

Objective: To investigate the current status of prevention and control of occupational hazards in a city in 2017, to understand the capability to prevent and control occupational hazards and the level of occupational health supervision and management, and to propose measures to urge employers to assume the main responsibility for the prevention and control of occupational diseases. Methods: An analysis of the main factors influencing the prevention and control of occupational hazards in the city was performed to screen out six semi-quantitative assessment indicators (including the training of the main responsible persons and occupational health management personnel in companies) and four qualitative assessment indicators (including the coverage of supervision and inspection of occupational hazards performed by the district safety supervision department) , which could be used to measure the prevention and control effects of regional occupational hazards. Each indicator was scored. The typical investigation method was used to do data review and on-site inspection of 170 companies, 17 district-level occupational health supervision departments, and 16 sub-district (township) occupational health supervision departments in the city from October to December, 2017. The prevention and control of occupational diseases in each district was scored, and the completion rate and completion situation of each indicator in the city were analyzed. Results: The mean score of prevention and control of occupational hazards in the city was 84.9. The scores of two districts were relatively high, being 88.9 and 88.7, respectively; the scores of 9 (52.9%) districts were higher than 85. The pass rate of training for the main responsible persons and occupational health management personnel in companies in the city was 95.9%, the pass rate of occupational health training for workers was 84.7%, the pass rate of occupational health examination for workers was 96.5%, the pass rate for the inspection of occupational hazardous factors in workplaces was 95.3%, the pass rate for notifying occupational hazards in workplaces is 95.9%, and the pass rate for applying the warning signs of occupational hazards in workplaces was 76.5%. Conclusion: The awareness of the importance of prevention and control of occupational hazards in all districts of the city has been increased, but the effectiveness of occupational health training for workers needs to be strengthened. The supply and demand of occupational health technical services are still not matched, and the ways and methods of occupational health supervision and inspection need to be improved.

Occupational Health and Safety in Healthcare Settings – Effect of Training on the Knowledge of Resident Doctors

Background: Over the past years several diseases and disorders associated with different kinds of occupations have been identified, including healthcare. It is important for medical personnel especially resident doctors to have adequate knowledge of occupational health and safety and prevention of occupational hazards. Objective: To assess the knowledge among resident doctors regarding occupational health and safety in healthcare settings, and the effect of training on the same. Methodology: A before and after intervention study without control was done among a group of resident doctors of a medical college in Delhi. Training on occupational health and safety was given to the study participants in the form of a two-day workshop. Pre- and post-test questionnaires filled by the participants were scored and the mean scores were compared and tested for statistically significant difference using Mann Whitney U test. Results: The study was done on 17 post-graduate resident doctors. The mean post test score was higher than the mean pre-test score and the difference was statistically significant at p<0.05. Conclusion: Training of doctors and other health personnel on occupational health and safety and prevention and control of occupational hazards can prove to be effective in improving their knowledge regarding the same.

Nurses' but not supervisors' safety practices are linked with job satisfaction.

To test the associations of safety practices as reported by nurses and their respective unit supervisors with job satisfaction. Psychosocial workplace factors are associated with job satisfaction; however, it is unknown whether nurses and supervisors accounts of safety practices are differentially linked to this outcome. Cross-sectional study design including nurses (n=1052) nested in 94 units in two hospitals in Boston (MA, USA). Safety practices refer to the identification and control of occupational hazards at the unit. Safety practices were measured aggregating nurses' responses per unit, and supervisory levels. Individual's job satisfaction for each nurse was the response variable. Supervisors assessed safety practices more favourably than their unit nursing staff. Adjusted random intercept logistic regressions showed that the odds of higher job satisfaction were higher for nurses at units with better safety practices (OR: 1.67, 95% CI: 1.04, 2.68) compared with nurses at units that averaged lower safety practices. Supervisors' reports of safety practices were not correlated with the job satisfaction of their staff. Adequate safety practices might be a relevant managerial role that enhances job satisfaction among nurses. Nursing supervisors should calibrate their safety assessments with their nursing staff to improve nurses' job satisfaction.

Applying Learning Theory to Safety and Health Training for Hispanic Immigrant Dairy Workers.

We designed a safety and health curriculum for dairy immigrant workers aiming to increase knowledge, encourage safe behavior, and reduce worker communication inequalities to prevent occupational injury and diseases. The design is largely based on the Taxonomy of Significant Learning and incorporated behavioral and adult learning theories and principles of occupational hazard control. Trainings were implemented with 836 Spanish-speaking workers from 67 farms in Wisconsin. Sixty-seven percent of workers reported never being trained before in dairy safety, 65% of these worked in dairy for 5 or fewers years, and 26% of workers reported being ever injured while working on dairy. Quantitative and qualitative evaluation of the trainings suggest that our curriculum successfully increased worker knowledge and promoted contemplation of safe practices. The overall knowledge gain of 25% was statistically significant ( p < .01). Workers recalled at least one key concept, expressed confidence of adopting at least one safety behavior, and mentioned their intention to communicate safety concerns to farmers. To our knowledge, this is the first Taxonomy of Significant Learning application to occupational safety and health education. Our curriculum can support dairy farmers' compliance with Occupational Safety and Health Administration's annual training requirements by providing our basic safety and health training to workers at early job stages.

Lung function and functional capacity among foundry workers using effective risk control measures.

Inhaled dust in the environment can trigger specific reactions in the airways and cause various respiratory diseases. Evaluate the lung function and functional capacity of foundry workers who are exposed to metals and use effective control measures. A cross-sectional study was realized with 108 workers at a bronze foundry and machining plant and in maintenance at a private university, both in Brazil. The workers were divided into two groups: the study group exposed to metals but using risk control measues and a control group not exposed to metal work. The Medical Research Council Questionnaire on Respiratory Symptoms and the International Physical Activity Questionnaire were administered, and lung function and functional capacity were evaluated. Comparative statistics were used to identify differences in the outcome measures between the two groups. The groups had similar personal and anthropometric characteristics and time on the job. Spirometry and peak expiratory flow presented no significant differences between the groups. And there was also no statistically significant difference between groups in functional capacity as assessed by performance on the six-minute walk test. Foundry industry workers in Brazil who were exposed to metal but used risk control measures had similar lung function and functional capacity when compared to the control group who were not exposed to metal. This is a positive results and maybe related to age, time exposure and control of occupational hazards. However, these workers need to continue being monitored in longitudinal studies.

Occupational hazards survey of specially supervised enterprises during 2011-2012 in one district of Shenzhen, China

To analyze the results of an occupational hazards survey of specially supervised enterprises (156 enterprise-times) during 2011-2012 in one district of Shenzhen, China and find out the changes in occupational hazards in these enterprises, and to put forward countermeasures for the prevention and control of occupational hazards. Occupational hazards monitoring results for specially supervised enterprises (156 enterprise-times) during 2011-2012 were included. Comparison and analysis were performed between different years, different industries, different occupational hazards, and different sizes of enterprises. A total of 1274 monitoring sites from these specially supervised enterprises were included, of which qualification rate was 73.55% (937/1274), and the noise monitoring sites showed the lowest qualification rate. The overall qualification rate in 2012 (70.37%) was significantly lower than that in 2011 (80.94%) (χ(2) = 15.38, P < 0.01). In electronics industry, the qualification rate in 2012 was significantly lower than that in 2011 (χ2 = 11.27, P = 0.001). Comparison of various hazards in different industries indicated that electronic enterprises and furniture enterprises had the lowest qualification rate in noise monitoring, printing enterprises had the lowest qualification rate in organic solvent monitoring, and furniture enterprises had the lowest qualification rate in dust monitoring. Comparison between different sizes of enterprises indicated that the qualification rate of large and medium enterprises in 2012 was significantly lower than that in 2011, while the qualification rate of small enterprises in 2012 was significantly higher than that in 2011 (P < 0.01 or P < 0.05). In the prevention and control of occupational hazards in specially supervised enterprises, special attention should be paid to the control of organic solvents in printing enterprises and noise and dust in furniture enterprises.
