INTRODUCTION: Medical errors commonly occur in medical imaging departments. These errors are frequently influenced by patient safety culture. This study aimed to develop a suitable patient safety culture assessment tool for medical imaging departments. METHODS: Staff members of a teaching hospital medical imaging department were invited to complete the generic short version of the Safety Attitude Questionnaire (SAQ). Internal consistency and reliability were evaluated using Cronbach's α. Confirmatory factor analysis (CFA) was conducted to examine model fit. A cut-off of 60% was used to define the percentage positive responses (PPR). PPR values were compared between occupational groups. RESULTS: A total of 300 complete responses were received and the response rate was 75.4%. In reliability analysis, the Cronbach's α for the original 32-item SAQ was 0.941. Six subscales did not demonstrate good fit with CFA. A modified five-subscale, 22-item model (SAQ-MI) showed better fit (goodness-to-fit index ≥0.9, comparative fit index ≥ 0.9, Tucker-Lewis index ≥0.9 and root mean square error of approximation ≤0.08). The Cronbach's α for the 22 items was 0.921. The final five subscales were safety and teamwork climate, job satisfaction, stress recognition, perception of management and working condition, with PPR of 62%, 68%, 57%, 61% and 60%, respectively. Statistically significant differences in PPR were observed between radiographers, doctors and others occupational groups. CONCLUSION The modified five-factor, 22-item SAQ-MI is a suitable tool for the evaluation of patient safety culture in a medical imaging department. Differences in patient safety culture exist between occupation groups, which will inform future intervention studies.

OBJECTIVE: To optimize the maintenance quality management of MRI equipment and ensure the quality and safety of its clinical use. METHODS: The data of failure time and repair time of a MRI equipment in three years were collected by magnetic resonance repair report system, and then the reliability, availability and maintainability(RAM) were studied and analyzed. RESULTS: The results of reliability analysis showed that the communication module was the key subsystem of the MRI equipment. The results of usability analysis showed that RF module was a key subsystem of MRI equipment. Maintainability results showed that the proportion of the MRI equipment not fully utilized due to maintenance-related problems was 2.58%. In order to improve the availability of MRI equipment, the maintenance time of MRI equipment should be shortened. CONCLUSIONS RAM-based analysis of MRI equipment can help hospital equipment managers to carry out the work of operation optimization, maintenance strategy formulation and safety management of MRI equipment.

In the process of occupational hazard management, computational fluid dynamics technology can be used to reflect the distribution pattern of occupational hazards in the production process, so as to quickly and accurately guide the formulation of occupational disease prevention and control programs. This paper summarizes and analyzes the current research results on the prevention and control of occupational hazards in workplaces through computational fluid dynamics technology, and describes the application of these research results in the process of occupational disease prevention and control. On this basis, this paper presents the problems and application limitations of existing research and points out the future key research directions, which are of great reference value for guiding further systematic and in-depth research on simulation, experimentation and management of occupational hazards that can cause occupational diseases.

Antimicrobial resistance (AMR) is increasingly becoming a threat to global public health, not least in low- and middle-income countries (LMICs) where it is contributing to longer treatment for illnesses, use of higher generation drugs, more expenditure on antimicrobials, and increased deaths attributed to what should be treatable diseases. Some of the known causes of AMR include misuse and overuse of antimicrobials in both humans and animals, unnecessary use of antimicrobials in animals as growth promoters, and lack of awareness among the public on how to protect antimicrobials. As a result, resistant organisms are circulating in the wider environment, and there is a need to consider the One Health approach to minimise the continuing development of AMR. Environmental Health, specifically water, sanitation and hygiene (WASH), waste management, and food hygiene and safety, are key components of One Health needed to prevent the spread of antimicrobial-resistant microorganisms particularly in LMICs and reduce the AMR threat to global public health. The key Environmental Health practices in the prevention of AMR include: (1) adequate WASH through access and consumption of safe water; suitable containment, treatment and disposal of human excreta and other wastewater including from health facilities; good personal hygiene practices such as washing hands with soap at critical times to prevent the spread of resistant microorganisms, and contraction of illnesses which may require antimicrobial treatment; (2) proper disposal of solid waste, including the disposal of unused and expired antimicrobials to prevent their unnecessary exposure to microorganisms in the environment; and (3) ensuring proper food hygiene and safety practices, such as sale and consumption of animal products in which adequate antimicrobial withdrawal periods have been observed, and growing vegetables on unpolluted soil. Environmental Health is therefore crucial in the prevention of infectious diseases that would require antimicrobials, reducing the spread of resistant organisms, and exposure to antimicrobial residues in LMICs. Working with other professionals in One Health, Environmental Health Practitioners have a key role in reducing the spread of AMR including health education and promotion, surveillance, enforcement of legislation, and research.

Bone-modifying agents currently include bisphosphonates and desumumab, which are the main drugs for the treatment of malignant tumor bone metastasis, hypercalcemia and osteoporosis. Due to its wide clinical application, the adverse events of this kind of drugs are gradually increasing and affecting the quality of life of patients. Therefore, it needs to arouse the attention of the majority of medical personnel. Based on the substantial evidence, the expert committee has thoroughly discussed the management of adverse reactions of bone modifying agents and put forward reasonable suggestions, to guide clinicians in the safety management of such drugs.

BACKGROUND: Increasing the establishment of integrated management systems (IMSs) is done with the purpose of leaving traditional management methods and replacing them with modern management methods. Thus, the present study sought to analyze the events and investigate the impact of IMS on health and safety performance indices in an Iranian combined cycle power plants. METHODS: This case study was conducted in 2012 in all units of the Yazd Combined Cycle Power Plant on accident victims before and after the implementation of IMS. For data analysis and prediction of indices after the implementation of IMS, descriptive statistics and Kolmogorov–Smirnov test, Chi-square, linear regression, and Cubic tests were conducted using SPSS software. RESULTS: The number of people employed in the power plant in an 8-year period (2004–2011) was 1,189, and 287 cases of work-related accidents were recorded. The highest accident frequency rate and accident severity rate were in 2004 (32.65) and 2008 (209), respectively. Safe T-score reached to below −3 during 2010–2011. In addition, given the regression results, the relation between all predictor variables with outcomes was significant (p < 0.05), except for the variable X1 belonging to the accident severity rate index. CONCLUSION: The implementation of safety programs especially that of IMS and its annual audits has had a significant impact on reducing accident indices and improving safety within the study period. Accordingly, health and safety management systems are appropriate tools for reducing accident rate, and the use of regression models and accident indices is also a suitable way for monitoring safety performance.
