A Mixed-Methods Investigation of Occupational Health Specialists' Knowledge and Application of Pen-and-Paper Observational Methods for Ergonomics Assessment.

OCCUPATIONAL APPLICATIONSErgonomic risk assessment is a key step in managing work-related musculoskeletal disorders. Diverse assessment methods exist, and errors may occur if inappropriate methods are selected. Understanding the level of knowledge, how to use methods, and exploring factors affecting erroneous usage of these methods, can provide useful information for health and safety regulatory authorities and decision-makers to identify problems and determine an action plan to eliminate them. We found that Iranian occupational health specialists have little knowledge about the types of pen-and-paper observational methods (OMs), and most of them use a limited number of these methods. Content analysis of interviews identified three main categories of influential factors and 12 subcategories. The main categories were educational, individual, and organizational factors. These results suggest the need for more effort to ensure that practitioners possess better knowledge and skills in the selection and application of pen-and-paper OMs.

Background Ergonomic risk assessment is a key step in managing ergonomics in the workplace. Errors in selecting risk assessment methods may occur during risk assessment and could invalidate the reliability of the results obtained.Purpose The aims of the present study were to investigate Iranian occupational health specialists' knowledge and application of pen-and-paper observational methods (OMs) for ergonomics assessment and to determine their influential factors.Methods We used a mixed-method design in two phases, combining quantitative and qualitative approaches. Quantitative data were collected from 237 occupational health specialists who were included in the study through purposive sampling of experts. In the qualitative phase, in-depth semi-structured interviews were conducted with participants from the first phase, and the factors associated with the selection and application of the pen-and-paper OMs were examined over a 6-month period.Results Participants were familiar with 13 out of 34 methods studied, and they had performed risk assessments with only nine of them. The most frequently used methods were RULA (95.4%), REBA (84.8%), QEC (65.4%), and ROSA (54.9%). Content analysis of interviews identified three main categories of influential factors and 12 subcategories. The main categories included educational, individual, and organizational factors.Conclusion Iranian occupational health specialists were found to have relatively limited knowledge about pen-and-paper OMs, and most of them use a limited number of these methods. These results suggest the need for more effort to ensure that practitioners possess better knowledge and skills in the selection and application of these methods. Creating stricter regulations regarding the qualifications of practitioners, modifying academic curriculum content, continuously monitoring the performance of practitioners, and holding retraining workshops in a purposeful manner could help minimize errors in selecting and applying pen-and-paper OMs.

Developing a Decision Aid Tool for selecting pen-paper observational ergonomics techniques: a quasi-experimental study.

BACKGROUND: A significant error that may occur during ergonomic risk assessment and invalidate assessment reliability corresponds to technique selection. This study aimed to develop a new tool called the Decision Aid Tool (DAT) to reduce pen-paper observational technique selection errors. METHODS: This quasi-experiment before-after study was performed in three phases. In the first phase, the participants' skills in technique selection were examined by showing them 20 videos of different single-task jobs. In the second phase, the DAT was designed using pen-paper observational techniques. Finally, in the third phase, 115 occupational health specialists included in the study through purposive sampling of experts evaluated the tool's efficacy. RESULTS: The results of the first phase showed that 62% of participants made an error in selecting the proper technique. The mean and standard deviation scores from the first and third phases were 11.4 ± 6.59 and 39.01 ±1.89, respectively. The mean scores increased significantly after using DAT, and 97.5% of participants could correctly select task techniques. CONCLUSIONS: The efficacy of DAT was confirmed in a quasi-experimental before-and-after study. Using DAT increases the participants' ability to choose the correct technique. The DAT can be functional for practitioners to select the pen-paper observational techniques correctly under the purpose of assessment, the body areas, and the characteristics of the task to be assessed.

Explaining the Challenges of Coping with Coronavirus Crisis in the Workplaces: A Qualitative Study.

Background: Workplaces play a highly important role in controlling or spreading the prevalence of coronavirus disease 2019 (COVID-19). Therefore, the lack of proper implementation of hygienic protocols in these environments might increase the risk of getting infected with the COVID-19 among the employees, following the increase of the COVID-19 at the family and community levels. This qualitative study aims to explain the challenges of coping with the coronavirus crisis in the workplaces. Methods: The present qualitative study was conducted with a conventional content analysis approach. We used purposeful sampling with maximum diversity in terms of working processes. Data were collected through semi-structured interviews. Interviews were performed to the point of information saturation. MAXQDA software version 10 was used for data management. Results: Through the content analysis of the interviews with the participants, we identified two main classes and nine sub-classes. The main classes included intra-organizational challenges (job nature, budget allocation problems, individual factors, disorganization, manpower and equipment, lack of commitment, and insufficient support of managers) and extra-organizational challenges (lack of accessibility to valid information, black market, and inter-sectorial coordination problems). Conclusion: The study findings indicated that organizations and industries face numerous internal and external challenges in coping with the COVID-19 pandemic. Paying attention to the mentioned limitations and attempting to eliminate them, especially by the governmental organizations, employers, and managers, could help in effectively confronting the COVID-19 pandemic.

Common errors in selecting and implementing pen-paper observational methods by Iranian practitioners for assessing work-related musculoskeletal disorders risk: a systematic review.

Objectives. This study aimed to determine the types and frequency of pen-paper observational methods (OMs) used by Iranian practitioners and to identify their errors in selecting and implementing these methods. Methods. This was a systematic review and analytical study of papers in which the OMs had been used. Scientific databases were analyzed from September 1970 to September 2018. Errors were determined based on a list of wrong practices both in the selection and implementation of methods. Three ergonomists carried out the process of identifying errors independently. Results. The most frequently used methods were rapid upper limb assessment (RULA), quick exposure check (QEC) and rapid entire body assessment (REBA), respectively. Errors in selecting and implementing pen-paper OMs were 53.3 and 36.4%, respectively. Conclusions. Despite the abundant number of pen-paper OMs, Iranian practitioners use few of them. The high rate of errors can indicate a lack of knowledge and skills among practitioners for selecting and implementing OMs. The development of decision-making tools may help practitioners to select appropriate pen-paper OMs for assessing different types of tasks.

Occupational stress and mental health among nurses in a medical intensive care unit of a general hospital in Bandar Abbas in 2013.

BACKGROUND: Many nurses have reported experiencing high levels of occupational stress in their work environment. Stress, as an outcome of stressful workplaces and tasks, affects nursing behavior in hospital wards. The objectives of this research were to determine the prevalence of occupational stress and mental health problems in nurses in the intensive care unit (ICU) at Shahid Mohammadi Hospital in Bandar Abbas in 2013 and to determine the relationship between occupational stress and mental health. METHODS: This cross-sectional study was conducted in 2013 on all of the nurses working in ICU at Shahid Mohammadi Hospital located in Bandar Abbas, Iran. Seventy-two nurses were selected as the population for this study, and all of them were female. Two questionnaires were used in this study, i.e., General Health Questionnaire-28 (GHQ-28) for assessing mental health and an occupational stress test for assessing job stress. Furthermore, the relationship between occupational stress and mental health was examined. One-way analysis of variance (ANOVA), independent samples t-test, and Pearson's product-moment correlation test were used to analyze the data. RESULTS: High and moderate levels of occupational stress were experienced by 83.9% and 10.7% of ICU nurses, respectively. The prevalence of mental disorders, somatic symptoms, anxiety, social dysfunction, and depression were 58.9, 60.7, 62.5, 71.4, and 10.7%, respectively. The findings of the independent samples t-test showed that somatic symptoms had significant relationships with age and working experience (p = 0.01). According to the independent samples t-test, there were no significant differences between somatic symptoms and working different shifts (p > 0.05). CONCLUSIONS: There was a high prevalence of occupational stress among ICU nurses. There was a significant relationship between occupational stress and mental health. Future interventions are needed to codify a comprehensive health program in this field to reduce occupational stress and enhance nurses' levels of mental health.

Knowledge, attitudes, and practice of drivers towards traffic regulations in Bandar-Abbas, Iran.

INTRODUCTION: Traffic injuries are among the leading causes of death and disability in many countries. The knowledge, attitudes, and practice of drivers towards traffic regulations are key factors in decreasing traffic injuries and deaths. The objectives of this research were to study the knowledge, attitudes, and practice of taxi drivers towards traffic regulations in Bandar-Abbas, Iran, and to determine the relationships between demographic features and knowledge, attitudes, and practice of taxi drivers towards traffic regulations. METHODS: This cross-sectional study was done in 2014 in Bandar-Abbas, Iran (Hormozgan Province). To study the knowledge, attitudes, and practice of 241 intra-city taxi drivers towards traffic regulations, researchers developed questionnaires and a checklist. The chi-squared test was performed to determine the relationships between knowledge, attitude, and practice of drivers towards traffic regulations and demographic features. RESULTS: Among the 241 drivers, 50 of them (20.7%) thought that the seat belt could cause discomfort while driving, and 107 (44.4%) did not wear a seat belt while driving. The study determined that there was a significant difference between the knowledge and work experience of the drivers (p = 0.014). The 94 drivers (43.5%) in the 31-40 year age group had positive attitudes towards traffic regulations (among 216 drivers expressed positive attitudes) and 92 (44.4%) of the drivers in this age group had safe practices towards traffic regulations (among 207 drivers with safe practice). CONCLUSION: Many of the taxi drivers in Bandar-Abbas had inadequate knowledge, less positive attitudes, and risky practices towards traffic regulations. Implementation of effective intervention programs may increase the taxi drivers' knowledge, attitudes, and practices towards traffic regulations.
