Determination and prioritization of factors affecting the occurrence of needle stick injuries among healthcare workers using techniques of Delphi and fuzzy analytical hierarchy process (FAHP).

INTRODUCTION: Needlestick injuries (NSIs) are a major hazard in the workplace for healthcare workers. To prevent these injuries, it is essential to determine the important factors affecting the occurrence of them. This study aimed to identify, classify and prioritize these factors using techniques of Delphi and fuzzy analytical hierarchy process (FAHP). METHODS: This descriptive-analytical study was conducted in 2022. Firstly, the factors affecting the occurrence of needlestick injuries were identified by the literature review. Moreover, the Delphi technique was used to identify the factors. 20 experts (physicians, nurses, and occupational health experts) participated in the steps of the Delphi method. Then, these factors were grouped into six groups. In the next step, the fuzzy analytical hierarchy process (FAHP) was applied to prioritize the factors. For this purpose, the pairwise comparison questionnaire was designed and filled out by 20 experts. Finally, data were analyzed using MATLAB software (version 2018a). RESULTS: 42 factors (31 factors extracted from the literature review and 11 factors obtained from the Delphi technique) were identified in this study. These factors were categorized into six groups. Based on the results, the relative weight of non-demographic personal factors, tool and technology factors, job factors, organizational factors, demographic personal factors, and environmental factors were computed by 0.200, 0.185, 0.184, 0.157, 0.142, and 0.133, respectively. CONCLUSION: These results determined the importance of the factors affecting the occurrence of needlestick injuries. These findings can be useful for planning preventive measures.

The impact of emotional intelligence and personality traits on the occurrence of unsafe behaviors and needle stick injuries among the nurses.

This study was aimed to investigate the effect of emotional intelligence and some personality traits on safe behavior and needle stick injuries among the nurses. This cross-sectional study was performed on 200 nursing staff of a hospital in Iran. To collect data, individuals were asked to complete several questionnaires, including demographic questionnaire, domain-specific risk-taking questionnaire, Rosenberg self-confidence questionnaire, Buss-Perry aggression questionnaire, Goleman emotional intelligence questionnaire, and safe behavior questionnaire. Also, the number of needlestick injuries in the participants was extracted from their medical records. Data were analyzed using the SPSS software (version 22), and path analysis was performed using AMOS software. The prevalence of needle stick injuries in the subjects was estimated by 45.5 percent. The results showed that increasing risk-taking, increasing aggression, decreasing self-confidence, and decreasing emotional intelligence reduced safe behavior and increased the number of needle injuries (P < 0.001). In the present study, some personal traits affecting the occurrence of needlestick injuries were identified. It is recommended that people without these negative traits are applied in dangerous occupations with a high probability of needle stick injuries.

The impact of ergonomic-educational interventions on reduction of musculoskeletal symptoms among employees of oil and gas installations in Iran.

BACKGROUND: Musculoskeletal disorders can cause increased absenteeism, costs, and injuries. OBJECTIVE: The present study was aimed to investigate the impact of ergonomic-educational interventions on the reduction of musculoskeletal symptoms among employees of oil and gas installations. METHODS: This interventional study was conducted on 1243 male workers of oil and gas installations in the south of Iran. The Nordic questionnaire and quick exposure check (QEC) method were used to evaluate the risk of developing musculoskeletal disorders in the participants. Then, the educational interventions via training sessions, designed educational booklets and leaflets, and prepared educational film were performed. Data were collected at the times of two months before and six months after the interventions. RESULTS: The prevalence of musculoskeletal symptoms, at least in one of the body areas, was equal to 71.28%. The results showed that the prevalence of these symptoms significantly decreased in all body areas after the educational interventions (P <0.028). The highest reduction rate occurred in the regions of wrists and hands (52.77%), knees (47.17%), and waist (47.13%), respectively. Moreover, the results indicated that the mean value of the total score of quick exposure check (QEC) had a meaningful decrease from 0.92 to 0.54 after the educational interventions (P <0.0001). CONCLUSION: The planned educational interventions efficiently reduced the prevalence of musculoskeletal symptoms and the ergonomic risk levels estimated by QEC in the research population.
