In this article, we study the impact of teamwork on an organization’s performance, considering a cooperative game’s framework. To promote teamwork culture, performance indexes were considered both individually and collectively, and by comparing the scores that every employee earned individually and collectively, their differences became obvious. In this approach, a cooperative game’s model was used in order to improve the organization’s performance. The proposed model, in addition to evaluating the organization and employee’s activities, implemented all payments, including overtime pay, rewards, etc., fairly and along with increasing performance and satisfaction. The cooperative approach created effective communications between employees and authorities and enhanced their motivation for teamwork. Moreover, results could be used for decisions related to employees (such as promotion, transition, firing, and secondment), analysis of training requirements, employees’ development, and research and plan valuation. Our findings show that the collaborative coefficient (CC) is a key factor in increasing productivity and improving the efficiency of an organization in the long run. The collaborative coefficient is a new concept in teamwork that has rarely been considered in scientific research.

Background: Educational planning and managing critical situations of accidents and disasters are among the most important issues. Triage, which means the classification of patients and injuries based on specific situations and needs, is one of the important tasks of hospitals at times of disasters. In this study, triage knowledge and practice of nurses working in hospitals affiliated to Ilam University of Medical Sciences are evaluated. Materials and Methods: This is a cross-sectional and analytic study conducted in 2017. The statistical population comprised all nurses working in Ilam Medical Sciences hospitals. Using Cochran's formula, 174 people were sampled and 160 of them completed the study questionnaires and returned them. The main tool of collecting data was a researcher-made questionnaire based on Canadian triage scale. Validity of the questionnaire was assessed by 10 members of the Ilam University of Medical Sciences. The reliability of the questionnaire was between 0.83 and 0.89 using Cronbach α coefficient. The obtained data were analyzed using descriptive and inferential statistics in SPSS. Results:The Mean±SD duration of nurses' working in the emergency department was 5.2±3.4 years, of which 46.2% had an experience of using triage. The Mean±SD score of nurses' knowledge and practice of triage were respectively 10.44±2.11 and 9.22±2.14 out of 15. There was no significant relationship between work experience, gender and age with knowledge and practice of triage, but there was a significant relationship between knowledge and practice of nurses about triage with nursing educational degree. Conclusion:The level of nurses' knowledge and practice of triage in hospitals of Ilam University of Medical Sciences is moderate.
