目的 探讨多学科协作诊疗模式(multiple disciplinary team,MDT)在急诊危重批量伤患者救治中的应用,评价MDT诊疗模式在救治急诊危重批量伤患者中应用的价值.方法 抽取2015年9月-2017年9月航天中心医院急诊科收治的87例危重批量伤患者进行对比研究,按照所采取的治疗模式分为MDT诊疗组42例和非MDT诊疗组45例,MDT诊疗组采取MDT诊疗模式进行治疗,非MDT诊疗组则行传统救治模式进行治疗,观察并比较两组急诊诊断准确率、抢救成功率、平均住院日的变化情况.结果 ①比较急诊诊断准确率、抢救成功率,MDT诊疗组和非MDT诊疗组差异有统计学意义(P＜0.05),MDT诊疗组的急诊诊断准确率、抢救成功率明显高于非MDT诊疗组;②比较平均住院日,MDT诊疗组和非MDT诊疗组差异有统计学意义(P＜0.05),MDT诊疗组平均住院日明显低于非MDT诊疗组.结论 在急诊实施MDT诊疗模式能够提高急诊危重批量伤患者的急诊诊断准确率、抢救成功率,降低患者平均住院日,在急诊积极推行MDT诊疗模式能够有效提高急诊对危重批量伤患者的救治能力,值得推广.“,”Objective To explore the application and assess the effect of multiple disciplinary team (MDT) working model in treating critical mass casualty in emergency department. Method 87 critical mass casualty from September 2015 to September 2017 in our hospital were enrolled into comparative studies. Patients were divided into MDT treatment group (42 cases) and Non-MDT treatment group (45 cases) according to the treatment mode. MDT treatment group were treated with MDT diagnostic model while the Non-MDT treatment group were treated with traditional treatment.The diagnosis accuracy rate,rescue success rate and average hospitalization day were compared between the two groups. Results ①There were significant difference in diagnosis accuracy rate and rescue success rate between the two groups (P＜ 0.05), while the diagnosis accuracy rate and rescue success rate were obviously higher in MDT treatment group.② There were significant difference in average hospitalization day between the two groups(P＜ 0.05) and the hospitalization day were significant decreased in MDT treatment group. Conclusion The implement of MDT working model in emergency department can significantly improve the diagnosis accuracy rate and rescue success rate in critical mass casualty and reduce the average hospitalization day. The actively implement of MDT working model can effectively improve the rescue ability of emergency department in treating critical mass casualty. MDT working model are worth of being generalized.
