Design and Validation of a Health Literacy Assessment Tool for COVID-19 Among Iranian Workers.

BACKGROUND: The workforce is an organization's most important asset, and ensuring their health and safety is crucial for achieving the organization's mission and goals. OBJECTIVE: The objective of this study was to design and validate a health literacy tool for COVID-19 among Iranian workers. METHODS: This cross-sectional study involved a total of 201 participants. A personal information questionnaire was administered, and The Health Literacy Assessment (HLA) Tool was used to collect data specifically related to COVID-19. The HLA for COVID-19 was designed and developed, and the validity of the tool was evaluated through face, content, convergent, and construct validity analyses. To examine convergent validity, the Perceived Stress Scale was used. The reliability of the questionnaire was assessed using internal consistency measures, such as Cronbach's alpha coefficient. KEY RESULTS: The mean content validity index was 0.93, indicating high content validity. Confirmatory factor analysis results supported the five-dimensional structure of the tool. Significant correlations were found between the HLA for COVID-19 and perceived stress levels. The Cronbach's alpha coefficient for all items was 0.84, indicating high internal consistency. CONCLUSION: The HLA for COVID-19 is a concise, reliable tool for measuring health literacy related to COVID-19 among Iranian workers. Assessing COVID-19 health literacy in this population can be useful in evaluating the effectiveness of government officials, the media, and the medical and scientific community in providing necessary information.

PLAIN LANGUAGE SUMMARY: The workforce is an organization's most important asset, and ensuring their health and safety is crucial for achieving the organization's mission and goals. The objective of this study was to design and validate a health literacy tool for COVID-19 among Iranian workers.The HLA for COVID-19 is a concise, reliable tool for measuring health literacy related to COVID-19 among Iranian workers. Assessing COVID-19 health literacy in this population can be useful in evaluating the effectiveness of government officials, the media, and the medical and scientific community in providing necessary information. Health literacy plays a crucial role in disease prevention, including the control of epidemics. It can be particularly valuable in empowering societies affected by crises like the COVID-19 pandemic, which has had a profound impact on all aspects of human life. In international studies focused on assessing health literacy during the pandemic, researchers utilized public health literacy scales. However, only one study developed a specific scale to evaluate people's health literacy concerning COVID-19.

Assessment of Masks Used by Healthcare Workers: Development and Validation of a Mask Qualitative Assessment Tool (MQAT).

Background: Respiratory masks can provide healthcare workers with protection from biological hazards when they have good performance. There is a direct relationship between the visual specifications of a mask and its efficacy; thus, the aim of this study was to develop tools for qualitative assessment of the performance of masks used by healthcare workers. Methods: A mixed-methods design was used to develop a qualitative assessment tool for medical face masks (MFM) and particle filtering half masks (PFHM). The development of domains and items was undertaken using observation and interviews, the opinions of an expert panel, and a review of texts and international standards. The second phase evaluated the psychometric properties of tools. Finally, the validated Mask Qualitative Assessment Tools (MQAT) were used to assess six samples from 10 brands of the two types of masks. Results: MQAT-MFM and MQAT-PHFM shared 42 items across seven domains: "cleanliness," "design," "marking, labeling and packaging," "mask layers," "mask strap," "materials and construction," and "nose clip." MQAT-MFM included one additional item. MQAT-PHFM included another nine items associated with an eighth "Practical Performance" domain, and the valve version had another additional "Exhalation Valve" domain and six items. The evaluation indicated 80% compliance for MFM and 71% compliance for PFHM. "Marking, labeling and packaging" and "Layers" were associated with the least compliance in both types of masks and should be checked carefully for defining mask quality. Conclusion: MQAT can be used for immediate screening and initial assessment of MFM and PHFM through appearance, simple tools, and visual inspection.

Development and validation of a Nurse Station Ergonomics Assessment (NSEA) tool.

BACKGROUND: Nurse stations are one of the primary units for supporting effective functioning of any hospital. They are important working environments that demand adherence to known ergonomic principles for the well-being of both staff and patients. The aim of this study was to develop a psychometrically tested tool for the assessment of the ergonomic conditions of nurse workstations in hospitals. METHODS: Ten hospitals, with a total of 133 nurse stations participated in this mixed-methods research. The domains and items of the tool were developed based on a literature review, an experts' panel, and interviews with nurses. RESULTS: The final nurse station ergonomic assessment (NSEA) tool has good psychometric properties. Validity was assessed by face validity and content validity. Reliability was evaluated using inter-rater agreement and test-retest reliability analyses with a four-week interval between assessments. The NSEA is comprised of 64 items across eight domains: layout and location (7 items), workspace (11 items), security-safety (5 items), environmental conditions (8 items), counter (8 items), chair (13 items), desk (9 items), and monitor (3 items). CONCLUSIONS: The NSEA adds to the literature a tool for managers to ensure they comply with legal requirements and support best practice for those working on hospital wards. The NSEA can be used to identify challenges for healthcare professionals who use nurse stations and support the execution of targeted interventions to improve human-environment interactions.

Musculoskeletal disorders and selecting an appropriate tool for ergonomic risk assessment in the dental profession.

BACKGROUND: Work-related Musculoskeletal Disorders (WMSDs) are major challenges in the occupational health services industry. Dental practitioners are regularly subjected to ergonomic risks, which can cause Musculoskeletal Disorders (MSDs) in various body regions. OBJECTIVE: This comparative cross-sectional study aimed to investigate MSDs and select a proper ergonomic risk assessment method in dental practice. METHODS: This study was conducted on 70 dentists and 70 administrative staff of dental offices (comparison group) from Shahroud, Iran. The Cornell Musculoskeletal Discomfort Questionnaire (CMDQ) and two observational ergonomic risk assessment methods, including Quick Exposure Check (QEC) and Rapid Entire Body Assessment (REBA), were utilized. RESULTS: The results suggested that the mean score of musculoskeletal discomforts was significantly higher in dentists than in the administrative personnel. Additionally, the results of multiple regression analysis technique inferred that job tenure, working hours, and age had a significant impact on total MSDs. Regular exercise was found to significantly reduce neck discomfort complaints. It was also found that QEC was more effective in predicting musculoskeletal discomforts compared to REBA. CONCLUSION: Considering the high incidence of WMSDs in dentists, various interventional measures revolving around ergonomically redesigned workstations, enhanced physical working conditions, and ergonomic training courses are suggested.

Reliability was also evaluated using internal consistency. RESULTS: The final tool included 26 items in six domains, including tactile sensation, dexterity, grip strength, fitting, reliability and hand hygiene. The Cronbach's alpha was 0.82 for the total scale. CONCLUSION: The final tool had good validity and reliability. The findings of this study led to the development of a comprehensive standard tool that can be used to assess the ergonomic and safety status of medical gloves. IMPLICATIONS FOR NURSING MANAGEMENT: With this tool, problems related to medical gloves can be identified among nurses, and the necessary interventions can be predicted.

Lifestyle and Shiftwork: Designing and Testing a Model for Health Promotion of Iranian Nurses.

BACKGROUND: Lifestyle is one factor that forms the nurses' health, particularly those who work in shiftwork schedules. AIMS: The aim of this study was to design and test a model for health promotion of Iranian nurses. In this model, nurses' lifestyle was considered as the precedent, physical and mental health as the outcomes, and sleep disturbance and chronic fatigue as the mediators. METHODS: A cross-sectional study using structural equation modeling was conducted among 240 shiftworker nurses in Iran. The data collection was performed using the Persian versions of the Survey of Shiftworkers Questionnaire and Life Style Questionnaire. Bootstrap in Preacher and Hayes' Macro program was used for testing mediation. RESULTS: Lifestyle had a weak significant direct effect on physical (ß = 0.13, p < .04) and mental health (ß = 0.12, p < .02), and it had a significant indirect effect on physical health via chronic fatigue (ß = -0.11, p < .001) and sleep disturbance (ß = -0.05, p < .01). This variable only had a significant indirect effect on mental health via chronic fatigue (ß = -0.19, p < .001). The final model proposed a new significant path between sleep disturbances and chronic fatigue (ß = 0.22, p < .001). CONCLUSIONS: Therefore, the hospital officials can enhance the nurses' physical and mental well-being by providing interventions and training courses on aspects of healthy lifestyles, such as physical activity, avoidance of smoking, and maintenance of body weight.

Low cost ergonomic interventions to reduce risk factors for work related musculoskeletal disorders during dairy farming.

BACKGROUND: Workers engaged in dairy farming are exposed to awkward and poor postures that may result in work-related musculoskeletal disorders (WMSDs). OBJECTIVE: This study carried out ergonomic interventions in order to eliminate and reduce awkward postures in dairy farming. METHODS: This quasi-experimental study applied rapid entire body assessments (REBA) to evaluate the risks associated with each posture while performing the assigned tasks on a dairy farm in Iran to identify high and very high-risk tasks. A participatory ergonomics model was used that incorporated suggestions by dairy workers to design the used interventions. RESULTS: In the first intervention, by using an automatic transmission system for pouring milk, one high and one very high-risk task- pouring milk into a bucket and pouring milk from a bucket into a tank, respectively- were eliminated. In the second intervention, two high-risk tasks- filling corn containers and pouring corn into the milling machine- were eliminated by using a material conveying vacuum pump to transfer corn from the ground to the opening of the milling machine. In the third intervention, a simple and cheap holding device for the bag was designed to reduce the posture risk score from very high to medium. The fourth intervention involved the use of a shovel with a handle appropriate to the anthropometric characteristics of the workers that reduced the posture risk from very high to medium. CONCLUSIONS: The results indicated that applying participatory ergonomic principles along with low cost and simple designs with high performance resulted in significant reductions in postural risks pertaining to of musculoskeletal disorders on Iran dairy farms.

Validity and consistency assessment of accident analysis methods in the petroleum industry.

Background. Accident analysis is the main aspect of accident investigation. It includes the method of connecting different causes in a procedural way. Therefore, it is important to use valid and reliable methods for the investigation of different causal factors of accidents, especially the noteworthy ones. Objective. This study aimed to prominently assess the accuracy (sensitivity index [SI]) and consistency of the six most commonly used accident analysis methods in the petroleum industry. Methods. In order to evaluate the methods of accident analysis, two real case studies (process safety and personal accident) from the petroleum industry were analyzed by 10 assessors. The accuracy and consistency of these methods were then evaluated. The assessors were trained in the workshop of accident analysis methods. Results. The systematic cause analysis technique and bowtie methods gained the greatest SI scores for both personal and process safety accidents, respectively. The best average results of the consistency in a single method (based on 10 independent assessors) were in the region of 70%. Conclusion. This study confirmed that the application of methods with pre-defined causes and a logic tree could enhance the sensitivity and consistency of accident analysis.
