Postoperative pain is a common experience in patients hospitalized in surgical units. Therefore, controlling and mitigating it are one of the priorities in nursing. The purpose of this study is to determine the effects of training on the knowledge and attitudes nurses about postoperative pain in patients hospitalized in surgical units of teaching hospitals of Kerman, Iran, in 2014. This study uses a quasi-experimental design and is conducted on 60 nurses working at surgical units of teaching hospitals of Kerman, Iran, who were selected randomly through cluster sampling. For data collection, we used the Zanolin attitudes questionnaire and the Brockopp-Warden Pain Knowledge/Bias Questionnaire (BWPKBQ). We analyzed the data with the SPSS software product, v19, using parametric and nonparametric statistical tests (paired t-test and Spearman’s rank correlation coefficient). The mean score of knowledge increased from 13.61 ± 3.76 before the intervention to 19.35 ± 2.16 after the intervention. The mean score of attitudes grew from 80.58 ± 7.09 before the intervention of to 86.91 ± 5.49 after the intervention. A significant increase was observed in the scores of knowledge and attitudes after the intervention (P<0.0001). Pain management training programs both increased the knowledge and changed the attitudes of nurses about pain management and control.
