Objective:To explore the effect of multidisciplinary team (MDT) model on prognosis of patients with traumatic amputation.Methods:A retrospective case-control study was conducted to analyze the clinical data of 54 patients with traumatic amputation admitted to Chongming Branch of Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine from July 2014 to June 2019. There were 41 males and 13 females, aged 39-72 years with an average age of 52.7 years. A total of 29 patients treated using MDT model intervention were served as observation group, and 25 patients treated using routine responsibility system holistic nursing as control group. The self rating anxiety scale (SAS) score, self rating depression scale (SDS) score and improved Barthel index were compared between the two groups on the day of admission and at 2 weeks, 4 weeks and 8 weeks after operation.Results:There was no significant difference in SAS, SDS and improved Barthel index between the two groups on the day of admission ( P>0.05). At 2 weeks, 4 weeks and 8 weeks after operation, the SAS score in observation group was respectively (52.5±7.6)points, (48.3±7.1)points and (41.3±6.1)points, lower than those in control group [(58.0±12.0)points, (54.4±10.7)points and (50.4±9.3)points]; the SDS scores in observation group was respectively (52.6±8.8)points, (47.9±7.6)points, (43.8±5.7)points, lower than those in control group [(58.4±12.4)points, (53.2±10.9)points, (49.5±8.7)points]; the Barthel index score in observation group was respectively (57.2±8.9)points, (80.7±7.7)points, (94.7±3.9)points, higher than those in control group [(50.4±11.4)points, (70.9±9.5)points, (85.6±6.8)points] (all P<0.05). Conclusion:For patients with traumatic amputation, MDT model is conducive to reducing anxiety and depression of patients, can improve the quality of life, and is worthy of clinical application.
