Providing an approach to analyze the risk of central oxygen tanks in hospitals during the COVID-19 pandemic.

The central oxygen unit of hospitals is considered a high-risk unit, requiring high safety standards to maintain the integrity of the system during the COVID-19 pandemic. The linear reasoning assumption of conventional risk analysis methods cannot adequately describe these modern systems, which are characterized by tight connections and complex interactions between technical, human, and organizational aspects. Therefore, this study presents a new and comprehensive approach to oxygen tanks in hospitals during the COVID-19 pandemic. In this study, trapezoidal fuzzy numbers were used to calculate failure rates. After determining the probability of basic events (BEs), intermediate events (IE), and top event (TE) with fuzzy logic and transferring it into Bayesian Network (BN), deductive and inductive reasoning, and sensitivity analysis were performed using RoV in GeNIe software. The results of the case study showed that the IE of "Human Error" had the highest probability of fuzzy fault tree (FFT) and the probability of oxygen leakage was lower using FBN than FFT. According to the results, BE16 (failure to use standard and updated instructions) and BE12 (defects in the inspection and testing program of tank devices) had the highest posterior probability, while based on the FFT results, BE4 (defects in the external coating system of the tank) and, BE3 (Corrosive environment (acidity state)) had the least probability. According to the sensitivity analysis, basic events 10, 11, and 16 were the most important in the oxygen leakage event with a very small difference, which was almost in line with the results of posterior FBN (FBNPO). Updating the existing guidelines, fixing defects in the inspection of all types of tank gauges, and testing related equipment can greatly help the reliability of these tanks. Root cause analysis of these events provides opportunities for prevention and emergency response in critical situations, such as the COVID-19 pandemic.

Prevalence of job burnout in Iranian nurses: A systematic review and meta-analysis.

BACKGROUND: Nurses experience many job tensions, which lead to job burnout. The consequences of nurses' job burnout include absenteeism, reduced quality of patient care, interpersonal conflicts with colleagues, physical and mental problems, reluctance to provide care with patients, and quitting the job. OBJECTIVE: The present study aimed to investigate the prevalence of job burnout among nurses in Iran using a meta-analysis method. METHOD: The study was conducted through a meta-analysis method based on the PRISMA checklist. An unlimited search was conducted until 2020 to access the Persian and English papers in national databases, including Medlib, SID, Iranmedex, and Magiran, and databases including Cochrane, Science-Direct, PubMed, Scopus, and Web of Science. The keywords were "job burnout, nurse, and Iran." The data were searched and extracted by two researchers independently. All analyses were performed using version 2.0 of the Comprehensive Meta-Analysis (CMA) software. RESULTS: The prevalence of job burnout was investigated in 14 papers with a sample size of 2271 individuals with an average age of 31.44 years old, and a confidence interval of 55% (44-66%). Fars province, with 89.2%, had the highest, and Zanjan province, with 25.9%, experienced the lowest prevalence of job burnout. The overall prevalence of job burnout was 44% in males and 66% in females so that the highest prevalence was in women. CONCLUSION: The prevalence of job burnout in nurses was high in some areas of Iran. A special attention by managers is needed in this field because of the several roles played by the nurses in the healthcare system and the improvement of public health. Implementation of plans to reduce the job burnout and to improve the mental health of nurses by reducing work hours, giving more opportunities to them to express their opinion(s) in amount of salary and benefits, and creating better working conditions are recommended.

Risk Perception in the COVID-19 pandemic; a health promotion approach.

BACKGROUND: Many measures have been taken so far to minimize the outbreak of COVID-19, but it is still unclear to what extent people have understood the risk. Public participation plays a vital role in better and effective control of the coronavirus, and the importance of risk perception is effective in their preventive behavior. The aim of this study was to investigate the pandemic risk perception of coronavirus disease after began of pandemic in Iranian society. MATERIALS AND METHODS: This cross-sectional study was conducted in Iran in spring 2020. The data collection tool was a researcher-made questionnaire. The questions were extracted through interviews with experts and summarizing the opinions of public interviews, etc., The questionnaire was made available to the public through social media. The information was collected within 3 months. Quantitative data were reported as mean ± standard deviation and the qualitative data were reported as number and percent. Multiple linear regression and cross were also used to examine the demographic factors associated with risk perception. Data Analysis was performed using the SPSS version 21 statistical software. RESULTS: In this study, 402 individuals from 28 provinces (Azarbaijan Gharbi, Azarbaijan Sharghi, Alborz, Ardabil, Bushehr, Chaharmahal and Bakhtiari, Esfahan, Fars, Ghazvin, Gilan, Golestan, Hamedan, Hormozgan, Ilam, Kerman, Kermanshah, Khorasan Razavi, Khorasan Shomali, Khuzestan, Kohgiluyeh and Boyerahmad, Kurdistan, Lorestan, Mazandaran, Semnan, Sistan and Baluchestan, Tehran, Yazd, and Zanjan) of Iran participated. The risk perception score obtained from the sum of the scores of the questions was classified into quartiles. Accordingly, the risk perception score of (22.9) 92 people was very low, (26.6) 107 people low, (26.9) 108 people moderate, and (23.6) 95 people high. The results of multiple linear regression showed that the variables of gender (P = 0.008) and occupation (P = 0.013) had a significant relationship with risk perception. There was no significant relationship between risk perception and variables of age, marital status, and level of education (P > 0.05). CONCLUSION: The study showed that the risk perception of the people is more in categories of moderate to high. Assessing the risk perception of a pandemic can be helpful for preventive measurements and planning, and also, according to the results of the research, can be done appropriate educational interventions. Given that 47.5% of respondents were employees, of course, it should be noted that in sending a questionnaire virtually, there is usually a lot of loss and this is a limitation of the research. The results of this study can be useful in making prevention decisions and maintaining safety and health in the workplace.

Investigation of occupational fatigue and safety climate among nurses using the structural equation model.

BACKGROUND: Nursing is associated with many stressful situations that can lead to fatigue, reduced efficiency, and physical and mental illness. Safety climate is one of the most important indicators of safety management performance assessment that assesses employees' attitudes towards safety issues. OBJECTIVE: The purpose of this study was to investigate the relationship between safety climate and occupational fatigue in nurses. METHOD: This descriptive-analytical study was performed on nurses working in hospitals affiliated to Zabol University of Medical Sciences in 2019. 143 nurses were selected by the proportional sampling method and entered the study. Demographic questionnaires, Occupational Fatigue Inventory (SOFI), and Nurses' Safety Assessment Questionnaire were used for data collection. Statistical tests, including Independent T-Test, ANOVA, Mann-Whitney U, Kruskal-Wallis, and multivariate analysis of variance (MANOVA) were used to analyze the results using SPSS software version 21, and the multivariate structural equation was used for modeling. RESULTS: The mean scores of safety climate and occupational fatigue were 67.15±12.73 and 85.09±41.49, respectively. Job and demographic variables except for the second job (P-value = 0.065) had a significant effect on the variables of safety climate and occupational fatigue. There were also higher scores for occupational fatigue and all of its subscales in the group of women compared to the group of men. CONCLUSION: The results showed that occupational and demographic variables have significant effects on safety climate and occupational fatigue. There was a significant relationship between demographic variables of age, work experience, and education level with safety climate. There was also a significant relationship between education level, job satisfaction, satisfaction with colleagues and work experience with occupational fatigue. Therefore, paying attention to fatigue and safety climate of nurses in workplaces is recommended.

The effects of neck, core, and combined stabilization practices on pain, disability, and improvement of the neck range of motion in elderly with chronic non-specific neck pain.

BACKGROUND: Chronic non-specific neck pain is the most prevalent neck pain with notable impacts on the quality of life in the elderly. OBJECTIVE: The impacts of the neck, core, and combined stabilization practices on pain, disability, and improvement of the neck range of motion in the elderly with chronic non-specific neck pain were examined. METHOD: A quasi-experimental (open label) study was carried out through a cluster sampling in two phases in Tehran-Iran in 2017. Totally, 102 patients were randomly allocated to three groups of specific neck stabilization, specific core stabilization, and combined practices through envelope method. The intervention took 12 weeks. To measure the severity of pain and neck disability, the visual analog scale (VAS), neck disability index (NDI), and neck pain and disability scale (NPDS) was used. A goniometer was used to measure the range of the motion. To examine data, used SPSS (v.20). RESULT: The results, confirmed a significant decrease in pain over the time in the three therapeutic groups (p = 0.000). In addition, there was a significant difference between neck, core, and combined stabilization groups. Moreover, there was a significant increase in the angle of motion in all treatment groups with different treatment duration (P = 0.000). The highest increase in the angle of motion was after 12 weeks of practice in right lateral flexion (RLF) (p = 0.000). CONCLUSION: Twelve sessions of the neck, core, and combined stabilization practices can alleviate the pain and improve the strength in the elderly with chronic non-specific neck pain. In addition, compared to two other methods, the combined method was a more efficient way to improve the range of motion in patients.

Health in disasters in Iranian schools: A systematic review.

Iran is disaster-prone country in the world. Lack of awareness and failure to have a proper response to natural disasters cause heavy damages to nations and national assets. Risk management is essential to prevent, intervene, and fight disasters as it can attenuate the destructive effects. The present study reviews studies on health in disasters in Iranian schools with an emphasis on readiness to deal with crises. The study was carried out through a systematic search using keywords in Persian and English in Iranian and international databases such as Google Scholar, SID, Magiran, Web of Sciences, PubMed, and Scopus. The time range of the search included all articles published before September 2020. The reference lists were also checked to find more articles. Totally, 575 articles were found and full-text of 32 articles were examined. After omitting repetitious items, the articles were checked by two independent researchers in terms of inclusion and exclusion criteria so that 15 articles entered the final analysis phases. The target population consisted of students, teachers, managers, and experts of disaster resilience. The articles were mostly focused on earthquake, fire, and structural safety. Implementation of health school models through improving awareness and crisis management knowledge in school officials plays a key role in improving and preserving health in school environment and safety of students. Measures like paying more attention to safety of building and physical space of schools, adding crisis management skills to curriculum as practical educations, informing parents about such risk, and educating students about safety and prevention of risks are recommended.

Analyses and anticipating the future trend of accidents in an electricity distribution company of Iran: A time series analysis.

BACKGROUND: Many work-related fatalities happen every year in electricity distribution companies. This study was conducted to model accidents using the time series analysis and survey descriptive factors of injuries in an electricity distribution company in Tehran, Iran. METHODS: Data related to 2010 to 2017 were collected from the database of the safety department. Time series and trend analysis were used for data analyzing and anticipating the accidents up to 2022. RESULT: Most of the accidents occurred in summer. Workers' negligence was the reason for 75% of deaths. Employment type and type of injuries had a significant relationship (p <  0.05). CONCLUSION: The anticipating model indicated occupational injuries are going to have an increase in the future. A high rate of accidents in summer maybe because of the warm weather or insufficient skills in temporary workers. Temporary workers have no chance to work in a year like permanent workers, therefore acquisition experiences may be less in them. Based on the estimating model, management should pay attention to those sectors of the company where most of the risky activities take place. Also, training programs and using personal protective equipment can help to protect workers in hazardous conditions.

Investigating the match between anthropometric measures and the classroom furniture dimensions in Iranian students with health approach: A systematic review.

Ergonomics of schools and school furniture is one of the main issues in students' education. The proportion of school furniture to the anthropometric dimensions of students is one of the main ergonomic challenges in schools that affect students' health. This systematic review study aimed to examine the match between anthropometric measures and school furniture dimensions among Iranian students. A systematic review was carried out using databases to Google Scholar, SID, IRANDOC, PubMed, MEDLINE, and ScienceDirect and specific keywords to find papers published before March 2020. The references of seminal studies were also used to extend the search scope. Totally, 11 studies entered the review. The results showed that there was no proportion between classroom furniture and students in schools under study. This lack of proportion was evident at different grades in both boys' and girls' schools. The results showed a lack of proportion between classroom furniture and Iranian students. There is a need to design and procure furniture based on the anthropometric dimensions of the society that will help to health promotion of students. An updated national anthropometric databank of Iranian students can be a step to solve the problem.

Quality of life in health Iranian elderly population approach in health promotion: A systematic review.

BACKGROUND: The quality of life (QOL) is essential in all different stages of life; however, It is more important for older people as it can be effective in promoting their health. Therefore, the present study aimed to review the literature on the QOL in the Iranian elderly population. MATERIALS AND METHODS: The study was carried out as a systematic review. For this purpose, all databases were searched in March 2021. The keywords used for the search were "quality of life, elderly, older adults, aging, seniors, and Iran" along with the Persian equivalents. PRISMA protocol was used to screen articles. After removing duplicate and irrelevant items, two evaluators appraised the articles separately based on a researcher-made checklist derived from the SBEM and STROBE Statement standard checklists. RESULTS: The initial search yielded 3734 studies on the QOL in the Iranian elderly population. After screening and assessing the studies based on inclusion and exclusion criteria, 22 articles remained in the study. Most of the studies (cross-sectional) were conducted in Tehran using a 36-item Short-Form Health Survey to assess the QOL. The studies investigated sociodemographic determinants, physical and health-related behaviors, and spirituality and psychological determinants of the QOL. The sociodemographic determinants were the most common factors under study. The results showed that the role of gender and socioeconomic status was the strongest among the sociodemographic characteristics. A significant association was found between the QOL in the Iranian elderly population and factors such as depression and religious confrontation. CONCLUSION: In addition to chronic diseases, diseases of the oral and dental, as well as an unhealthy diet, should be considered in the elderly. Therefore, attention should be paid to all social, physical, and psychological variables that affect the QOL of older people.

Review of environmental challenges and pandemic crisis of Covid-19.

INTRODUCTION: Spread of novel coronavirus (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) has become a global and pandemic crisis. Some measures such as excessive use of disinfectants, increased production of nonbiodegradable waste, and water pollution will be the consequences of fighting against coronavirus disease 2019 (COVID-19), which harms the environment. Due to the fact that these effects will be identified in the long term, they may be neglected in the current situation. Therefore, the aim of this study was to investigate the environmental challenges caused by the SARS-CoV-2 pandemic crisis. MATERIALS AND METHODS: This was a review study conducted by search in databases, including Scopus, PubMed, and science direct until early May 2020. Keywords included "SARS-CoV-2," "COVID-19," and "Environment." Studies published in English and conducted in different countries were also selected for the analysis. The guidelines published by reputable organizations such as the World Health Organization, the Centers for Disease Control prevention (CDC), and the Ministry of Health have also been used in this study. CONCLUSION: The results of this study have shown that the COVID-19 virus, in addition to human damage and mortality, also affects the environment, and the damages and losses resulting from this pandemic may be identified later. Water pollution, increasing chemical pollution in the air, and increasing the production of nonbiodegradable waste are of these issues. For this purpose, it is recommended that, in addition to trying to improve the control of this pandemic, other environmental aspects in disinfection methods and disposal of dry and wet contaminated waste should be done more accurately and based on standard protocols. Infectious waste, in addition to the problem of standard sanitation, will become a major challenge that pollutes the environment. Based on this, it can be said that if home quarantine is observed voluntarily, in addition to reducing the risk of the SARS-CoV-2 and reducing the volume of visits to medical centers, it can be associated with another positive achievement, which is the reduction in waste production and protection of the environment.

Investigation of the relationship between the safety climate and occupational fatigue among the nurses of educational hospitals in Zabol.

INTRODUCTION: Some working and organizational conditions, such as psychological stress and shift work, are factors that threaten the health of staff working in health centers. These factors can cause fatigue in a long time. Fatigue reduces the ability to process information and decrease to respond to hazardous conditions and will affect the safety of the environment. Therefore, the purpose of this study was to determine the relationship between safety climate and occupational fatigue in nurses working in Zabol city. METHODS: This cross-sectional study was performed on 143 nurses working in educational hospitals of Zabol in 2019. The proportional sampling method was used, and the Swedish Occupational Fatigue Questionnaire and the Nurses Safety Questionnaire were used for data collection. Data were analyzed using independent t-test, analysis of variance, Mann-Whitney, Kruskal-Wallis tests, and SPSS-21 software. RESULTS: In the present study, 57.3% were women and 42.7% were men. The mean score of occupational fatigue was 85.09 ± 41.49, and the mean score of safety climate was 67.15 ± 12.73. There is a significant inverse relationship between occupational fatigue and safety climate. The comparison of safety climate and its subscales between occupational and demographic variables showed that the score of male supervisors' attitude was 01.36 ± 2.41 while the score of female supervisors' attitude was 8.88 ± 2.61, and this difference was significant. Furthermore, cumulative burnout, the attitude of supervisors, and the safety climate were significantly different between different educational levels. CONCLUSION: The results of this study showed that there is a relationship between occupational fatigue and safety climate. Issues related to safety and risk factors in hospitals due to the high risk of disease outbreak and mortality, in addition to being economical, are important in terms of the human aspect as well. In addition, the activity of nursing staff is more important compared to other groups because of providing health care and communicating with patients; thus, more education about the safety climate of the workplace environment in hospitals can reduce nurses' fatigue.

A review of studies on the COVID-19 epidemic crisis disease with a preventive approach.

BACKGROUND: COVID-19 is a highly contagious acute respiratory syndrome and has been declared a pandemic in more than 209 countries worldwide. At the time of writing, no preventive vaccine has been developed and tested in the community. This study was conducted to review studies aimed at preventing the spread of the coronavirus worldwide. METHODS: This study was a review of the evidence-based literature and was conducted by searching databases, including Google Scholar, PubMed, and ScienceDirect, until April 2020. The search was performed based on keywords including "coronavirus", "COVID-19", and "prevention". The list of references in the final studies has also been re-reviewed to find articles that might not have been obtained through the search. The guidelines published by trustworthy organizations such as the World Health Organization and Center for Disease Control have been used in this study. CONCLUSION: So far, no vaccine or definitive treatment for COVID-19 has been invented, and the disease has become a pandemic. Therefore, observation of hand hygiene, disinfection of high-touch surfaces, observation of social distance, and lack of presence in public places are recommended as preventive measures. Moreover, to control the situation and to reduce the incidence of the virus, some of the measures taken by the decision-making bodies and the guidelines of the deterrent institutions to strengthen telecommuting of employees and reduce the presence of people in the community and prevent unnecessary activities, are very important.

Health, safety, and environmental status of Iranian school: A systematic review.

Schools are considered as a first community, which plays an essential role in developing the child's life skills; thus, it is important to provide safety and health in these places. Accordingly, health, safety, and environmental (HSE) issues in schools are among the important issues that should be considered. Therefore, the purpose of this study was to review the studies conducted on the HSE status of Iranian schools. A systematic search of databases, including Google Scholar, SID, PubMed, IRANDOC, MEDLIB, and Science Direct, was performed using keywords by March 2020. The reference lists of key studies were also scanned to find additional articles that are suitable to include in this study. Twenty-five studies met the inclusion criteria. The results of the studies showed that the surveyed schools had favorable status in terms of HSE indicators, and only 12% of the studies reported poor status. About 88% of schools had favorable or average condition. Some cases, such as lack of safe emergency exit and inadequate ergonomic seats, have been reported, and some differences have been observed in schools in rural and urban areas. The results showed that the health and safety situation in most of the urban schools in Iran is good and relatively favorable. However, there have also been some problems; hence, the implementation of integrated HSE management is imperative to improve the status of schools. Personal health education and safety education are also recommended.
