Abstract: Objective: To investigate the current situation of the practices of the Standardized Nursing Practices for Intravenous Therapy (SNPIT) by some western region hospitals in China. To learn whether the nurses follow the standards and provide more information for pushing forward the standards. Methods: We investigated the SNPIT practices by the nurses from 110 hospitals in 10 provinces (or autonomous region) and 1 city in western region through cross-sectional study. We collected data about SNPIT practices by the questionnaire method from 14 779 nurses. Results: There was on average an infusion rate at 69.7%. The intravenous access instruments included catheter (47.1%) and steel needle (41.9%). There were 32.0%-92.7% of the nurses who knew and practiced the SNPIT strictly. The correct rate of the SNPIT practices was 41.1%. Conclusion: By data from 110 hospitals in 10 provinces (or autonomous region) and 1 city in the western region, the SNPIT has been widely used. However, the level of the practices remained not high enough. We suggest that the health and the administrative departments cooperate to further standardize the practices and promote the correct practices of the SNPIT by intensive training. It is safe and effective to regulate the nursing practices for intravenous therapy by practicing the SNPIT.
