Introduction: Maternity wards are of the highly sensitive wards in hospital. Errors in midwifery tasks can lead to life threatening risks for the mother and infant and higher medical costs. The present study is an attempt to qualitatively and quantitatively assess human errors in midwife staff using preventive human error analysis and engineering approach. Methods: The study was carried out as a case study in the maternity ward of Shoushtar Women Hospital. The participants were selected through convenient sampling and seven midwifery experts took part in the study. The work process in maternity ward was categorized into four categories of admittance, pre-labor, labor, and post-labor and the tasks and sub-tasks were determined based on hierarchical task analysis (HTA). Afterwards, human errors were quantified using EA technique and then, using PHEA technique a description of error in each tasks and error control solutions were provided. Results: The results clarified that the highest risks of human errors were in the tasks like cervix check, serum therapy, infant’s body check, preparing delivery equipment, and wearing personal protective equipment. Conclusion: Since, midwifery tasks are rule base and regulations and they are performed at a higher level of awareness and cognition, preventing errors entails continuous presence of a midwife next to patient’s bed along with an assistant midwife and codification of an infant examination checklist. Programming empowerment education including safety education to midwives is also recommended.

Introduction: Musculoskeletal disorders are the most common debilitating causes in workers and the main reason for medical leaves. Medial leave brings health, social, and economic consequences for individuals and society. The relationship between medical leaves due to pain and discomfort in different parts of the body and physical activity level at work, practice of sport, and leisure time in workers in cement industry in 2019 was examined. Methods: A descriptive-analytical study was conducted on 150 workers of a cement factory. The participants were selected randomly. Data gathering tools were demographics form, Nordic Musculoskeletal Questionnaire, and Baecke Physical Activity Questionnaire and the collected data was analyzed using SPSS (v.22). Results: The participants noted that the main painful areas over the past year were the waist, knee, ankle, and neck. There was a significant relationship between medical leave due to pain in the neck and overtime work. There was a significant relationship between the type of work activity and medical leave due to a pain in knee and ankle. Conclusion: The workers who used such medical leaves had a higher PAL at work. PAL at work increased the requests of medical leaves due to the pain in knee and waist. The PAL at sport practice decreased the rate of request for medical leave due to a pain in the Waist and Knee.

Introduction: Job burnout is a common phenomenon in health care employees who need to deal with and witness people’s problems and expectations. By definition, occupational cognitive failures appear as problems in performing daily tasks like forgetting them or having difficulty in focusing on them. The present study is an attempt to investigate the relationship between job burnout and occupation cognitive failures in nurses of educational hospitals. Methods: This descriptive-analytic study was done in 2018 and consisted of nurses from the Ardebil Hospital (n= 2,250). Using the Cochran formula, 328 hospital nurses were selected from different units by simple random sampling method. The data were collected by two professional health experts through interviewing and completing demographic questionnaires, job burnout questionnaire, and occupational cognitive failure questionnaire. Statistical analyses was performed in SPSS19. Results: A total of 328 nurses participated in the study. The mean age of the subjects was 34±8 years, varying from 22 years to 58 years. Occupational cognitive failures increased with the increase in emotional exhaustion and depersonalization; while it decreased with an increase in individual accomplishment. Conclusion: There was a significant relationship between occupational cognitive failure and different dimensions of job burnout. In addition, different dimensions of job burnout (Emotional Exhaustion, Depersonalization, and Personal accomplishment) could be associated with possible errors in information processing (memory, attention, and functioning).
