To explore the application and research of multi-disciplinary team(MDT) in the treatment of chronic wounds in Qinghai area.

Three hundred patients with chronic wound treated in Qinghai Provincial People′s Hospital from June 2017 to June 2020 were randomly divided into observation group and control group according to random number table method, with 150 cases in each group. The observation group was given MDT mode treatment and nursing, and the control group was given ordinary treatment and nursing. The wound healing, the changes of psychological anxiety and depression[self rating anxiety scale(SAS), self rating depression scale(SDS)], length of stay and hospitalization expenses, wound assessment [wound bed score(WBS), Bate Jensen wound assessment system(BWAT), TIME-H, total subscale of pressure sore healing(PUSH) scores] of the two groups were observed before and after treatment. The data were compared by t-test and chi-square test.

(1) Wound healing: the wound healing rate of the observation group was 87.33% (131/150), and that of the control group was 77.33% (116/150). The wound healing rate of the observation group was significantly higher than that of the control group, the difference was statistically significant(χ²=5.625, P<0.05). (2) SAS, SDS scores: there were no statistically significant differences in SAS scores [(66.25±7.14), (65.63±6.26) points] and SDS scores [(68.56±8.03), (69.10±7.85) points] between the observation group and the control group before treatment (t=0.735, 0.589; P>0.05). SAS scores [(48.19±8.32), (55.41±7.62) points] and SDS scores [(46.19±9.04), (57.18±7.25) points] decreased significantly after treatment, the observation group was smaller than the control group, and the differences were statistically significant (t=7.838, 11.615; P<0.05). (3) Average hospitalization time and average hospitalization cost: the average hospitalization time of the observation group [(7.04±1.15) d] was shorter than that of the control group [(9.62±1.42) d], and the average hospitalization cost of the observation group [(7426.45±278.19) yuan] was less than that of the control group [(8215.73±317.46) yuan], the differences were statistically significant (t=17.792, 153.201; P<0.05). (4) WBS, BWAT, TIME-H and PUSH: there were no statistically significant differences in WBS [(11.77±2.12), (12.04±2.03) points], BWAT [(64.16±5.21), (64.78±4.73) points], TIME-H [(10.16±1.27), (10.45±1.32) points], PUSH [(15.19±2.10), (14.98±2.45) points] between the observation group and the control group before treatment (t=1.127, 1.079, 1.939, 0.797; P>0.05), and BWAT [(49.21±4.86), (57.15±7.30) points] after treatment TIME-H [(4.27±1.66), (7.46±1.80) points], PUSH [(6.86±3.64), (9.03±2.85) points] decreased and WBS [(18.10±1.41), (15.81±1.36) points] increased. The treatment effect of the observation group were better than those of the control group, and the differences were statistically significant (t=14.317, 11.089, 15.956, 5.749; P<0.05).

MDT diagnosis and treatment mode can significantly promote the recovery of patients′ wounds, improve patients′ anxiety and depression, shorten hospital stay, reduce hospitalization expenses, and enable patients to obtain high-quality, whole process and professional treatment, which has certain clinical significance.
