To explore the clinical efficacy of multidisciplinary team (MDT) in the treatment of lower extremity threatened amputation, and to analyze the value of MDT in the treatment of lower extremity threatened amputation.

In this study, 86 patients who were at risk of amputation were retrospectively analyzed as control group. From January 2016 to June 2017, 60 patients (experimental group) who were treated with multi-disciplinary cooperation of traditional Chinese and western medicine in Gansu Provincial Hospital of TCM were compared and analyzed. The operation times, hospitalization time, hospitalization cost and limb salvage rate of the two groups were statistically analyzed. The long-term quality of life of patients in the trial group was evaluated by karnofsky performance scale(KPS) and the total clinical effective rate. T test was used to compare the number of operations, hospitalization time and hospitalization cost between the two groups, the success rate of limb salvage was compared with the χ² test.

Forty-six cases of limb salvage were successful in the experimental group, the success rate was 76.7%, while fifty-one cases in the control group, whose limb salvage success rate was 59.3%, the difference was statistically significant(χ²=4.779, P=0.029). There were (2.47±0.98) times of operation and (67.71±24.50) days of hospitalization in the experimental group, which were less than that in the control group, (2.98±1.05) times and (72.71±19.38) days, and the differences were statistically significant (t=-2.426, -2.237, P=0.017, 0.029). The total hospitalization expenses of the experimental group and control group were (9.20±4.16), (10.43±3.46) million yuan respectively, there was no significant difference between the two groups (t=-1.577, P=0.118). The KPS score was 62.39±11.77 in the last 6 months after operation in the experimental group, and the total clinical excellent and good rate was 78.26%.

MDT in the treatment of limb injury can significantly reduce the number of operations and hospital stay, and the long-term quality of life of patients with better clinical efficacy, but there is no significant reduction in hospitalization costs for patients.
