Risk assessment of nurse anesthetist job using hybrid AHP-CoCoSo

Background and purpose:Anesthesiology experts are exposed to significant risks due to advancements in anesthesia techniques and surgery, as well as the emergence of modern equipment and newer drugs, along with increased responsibilities and expectations. Therefore, the present study was conducted with the aim of providing a model for assessing the risks and hazards existing in this profession. Materials and methods:Initially, various sources, including interviews with experts and reviews of articles, were used to extract occupational risks in the field of nurse anesthetist. Subsequently, the study criteria, including consequence, probability, and exposure, were determined, and the weighting of these criteria was calculated using AHP.Finally, the prioritization of different risks was determined using CoCoSo. Results: Based on the results of determining the weights of criteria using the AHP, it was identified that the consequence with a weight of 0.43 is the most important criterion, while the exposure criterion with a weight of 0.27 is the least important criterion in this study. Also, among the investigated risks, inhaling anesthetic gases while wearing a mask, filling a vaporizer(R5) was selected as the most dangerous risk, followed by skin contact with scrubs or blood, patient's secretions or infected tissues(R1), needle sticking during venipuncture,patient's spinal anesthesia(R12), which were selected as the second and third most dangerous risks in anesthesiology experts job, respectively. Conclusion: In this study it was established that the proposed method can be used for risk assessment and prioritization of occupational hazards in the job of a nurse anesthetist as well as other professions
