Objective To explore the application of preoperative educative color manual for preoperative visits of pa-tients. Methods A total of 368 patients who were to receive selective operation were randomly assigned to an experi-mental group and control group, with 184 patients in each group. The two groups both received conventional preopera-tive visits one day before the operation, and the experimental group further received preoperative educative color manu-al. Indices such as anxiety scores, visit time, blood pressure and pulse of the two groups before and after the visits were compared, and postoperative satisfaction rate was surveyed. Results The differences of physiological indices after the visit such as anxiety scores, systolic pressure, diastolic pressure and pulse, plus visit time and postoperative satisfaction rate between the two groups were statistically significant(P<0.05). Conclusion The application of preoperative educative color manual for preoperative visits shortens visit time, effectively alleviate patients ’ preoperative anxiety and fear, and improves patients’ satisfaction.
