This study aimed to apply Neuman Systems Model in reducing the patient's anxiety level before surgery. Materials and methods: In a randomized controlled trail, 104 patients undergoing orthopedic surgery in Imam Ali Hospital, Bojnourd were studied. Data was collected using a demographic questionnaire and the Spielberger State-Trait Anxiety Inventory (STAI). Intervention was performed according to Neuman Systems Model that includes assessing the actual and potential stressors, identifying the objectives and strategies for action, and strengthening the defense and the natural flexibility. Assessment of anxiety was done in two groups (the experimental group according to Neuman Systems Model and the control group without any intervention) before and after the intervention. Data was analyzed by Chi-square test, t-test, and paired t-test using SPSS V. 16. Results: The results showed no significant difference in the level of anxiety before the intervention between the two groups. But after the intervention the anxiety level reduced significantly in experimental group (-18.94±16.1, P SP - 122 EP - 131 AU - Nasiry Zarrin Ghabaee, Davood AU - Bagheri-Nesami, Masoumeh AU - Abbaspour, Hadi AD - Lecturer, Department of Anesthesia, School of Nursing and Midwifery, North Khorasan University of Medical Sciences, Bojnourd, Iran KW - Neuman Systems Model KW - anxiety KW - nurse anesthesia KW - surgery UR - http://jmums.mazums.ac.ir/article-1-6016-en.html ER -
