多学科协作在多重耐药菌医院感染防控中的实践与效果

摘要

Objective To explore the practice and efficacy of multidisciplinary collaborative management in the prevention and control of multidrug-resistant organism(MDRO)healthcare-associated infection(HAI).Methods MDROs isolated from clinical specimens and MDRO infection in hospitalized patients in April 2012-March 2013(before intervention)and April 2013-March 2014(after intervention)were analyzed retrospectively.Since April 2013,multidisciplinary collaborative management has been implemented,isolation of MDROs and MDRO HAI in hospitalized patients before and after intervention were compared and analyzed.Results 798 and 833 MDRO strains were isolated before and after the intervention respectively,isolation rate of MDROs after intervention was lower than that before intervention(25.71%vs 31.89%,P<0.001).After the implementation of multidisciplinary collaborative management,incidence of MDRO HAI decreased from 0.94%before intervention to 0.63%;hand hygiene compliance rate of health care workers(HCWs)increased from 36.44%before intervention to 53.51%;compliance rate of contact isolation increased from 65.29%before intervention to 90.88%;rational usage rate of antimicrobial agents increased from 64.93%before intervention to 72.53%;specimen detection rate in patients with therapeutic antimicrobial use increased from 41.36%before intervention to 58.72%,differences were all statistically significant(all P<0.001).Conclusion The practice of multidisciplinary collaborative management can effectively implement the prevention and control measures of MDRO HAI,effectively reduce the occurrence of MDRO HAI.%目的 探讨多学科协作管理在多重耐药菌(MDRO)医院感染防控中的实践与效果.方法 回顾性调查2012年4月-2013年3月(干预前)与2013年4月-2014年3月(干预后)住院患者送检的临床标本中MDRO的检出及感染情况,自2013年4月开始实施多学科协作管理,比较分析干预前后患者MDRO检出及医院感染等情况.结果 干预前检出MDRO 798株,干预后检出MDRO 833株,干预后MDRO检出率(25.71%)低于干预前(31.89%),差异有统计学意义(P<0.001).实施多学科协作管理后,MDRO医院感染发病率由干预前的0.94%下降至0.63%;医务人员手卫生依从率由干预前的36.44%提高至53.51%;接触隔离执行率由干预前的65.29%提高至90.88%;抗菌药物合理使用率由干预前的64.93%提高至72.53%;治疗性使用抗菌药物标本送检率由干预前41.36%提高至58.72%;差异均有统计学意义(均P<0.001).结论 多学科协作管理的实践,能有效落实MDRO医院感染防控措施,有效减少MDRO医院感染的发生.
