ObjectiveTo explore the influence of 3D printing assisting educational intervention on the anxiety and sleep outcomes in the patients with trauma. MethodA total of 40 patients were selected between October 2014 and June 2015. The patients were randomly divided into the intervention group and control group with 20 patients in each. The outcomes from admitted to the 7th day after the surgery were evaluated, including visual analogue scale (VAS) scores, state-trait anxiety inventory (STAI) score, Likert score, and the condition of anxiety, pain, and sleep outcomes. ResultsThe differences in VAS scores, STAI scores, and Likert scores between the two groups were significant (P<0.05). Conclusions3D printing assisting educational intervention is a useful intervention that can improve post-operative outcomes for the patients with trauma.
