Objective:To explore the effect of evidence-based nursing best practice in postoperative pain management of neurosurgery patients.Methods:From January to June 2019, a cluster sampling method was used to select 146 neurosurgery patients from Huashan Hospital, Fudan University as the control group. We examined the patient's postoperative pain management status, and applied evidence-based nursing methods to obtain best practice evidence. From July to December 2019, the clinical evidence practice application model of the Australia Joanna Briggs Institute (JBI) Evidence-Based Health Care Center was used to apply evidence to postoperative pain management in neurosurgery patients. From January to June 2020, a cluster sampling method was used to select 146 neurosurgery patients as the observation group for re-examination after the application of evidence. The Modified American Pain Society Patient Outcome Questionnaire (APS-POQ-Modified) was used to investigate the postoperative pain perception beliefs and postoperative pain degree of the two groups of patients. The qualification rate of 146 pain nursing records before and after the application of the evidence was checked and the differences were compared.Results:The scores of 7 items regarding pain perception beliefs in control group were (3.45±1.42) , (3.21±1.21) , (3.58±1.53) , (3.37±1.26) , (3.63±1.34) , (3.55±1.06) , (3.45±1.35) , and those of observation group were (2.44±1.31) , (2.35±1.21) , (2.34±1.35) , (3.06±1.17) , (2.57±1.25) , (3.05±1.02) , (3.12±1.42) , the differences between the two groups were statistically significant ( t=6.346, 6.057, 7.350, 2.166, 6.994, 4.108, 2.027; P<0.05) . In control group, the current pain degree score was (2.34±0.89) , the most severe pain degree score within 24 hours after operation was (4.44±1.17) , and the average pain degree score within 24 hours after operation was (3.21±0.75) , and the scores in observation group were (1.98±0.96) , (3.54±1.10) , (2.46±0.70) , and the differences were statistically significant ( t=3.355, 6.731, 8.808; P<0.01) . The qualification rate of pain nursing record sheet before and after the application of the evidence was 67.12% (98/146) and 82.88% (121/146) respectively, the difference was statistically significant (χ 2=9.662, P=0.002) . Conclusions:The evidence-based nursing best practice can improve neurosurgery patients' pain perception beliefs, reduce the degree of postoperative pain of patients, and increase the qualification rate of nurses' pain nursing records.
