Introduction: Assessment of the performance of management systems is one of the main concerns of managers. The measure of success of an occupational health and safety management system is the ex-tent of its effectiveness. The effects of implementing an OHSMS on health and safety perfor-mance indices in a casting site located in Iran between 2015 and 2019 were examined. Methods: A retrospective descriptive-analytical study was conducted over five years on 21 depart-ments of a casting site. All the functional indices one year before the implementation of OHSAS 18001:2007 in 2015 until a year after the implementation (2019) were monitored and the data were analyzed using SPSS (v.19). Results: There was a significant decrease in occupational accidents after the implementation of OHSAS 18001:2007. Mechanical and ergonomic factors demonstrated significant improvements. There were improvements in the indices of opening health files for the personnel, personal protective equipment, education, instructions, legal requirements, commitment, and leadership. There was no significant change in chemical and physical factors. Conclusion: Implementation of the occupational health and safety manage-ment system was effective in the indices that needed managerial control with no or low expenses. However, it was not effective in indices in engineering and technical areas that needed more expenses.

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).
