某综合性医院2010年医院感染横断面调查结果分析

目的通过了解某院住院患者医院感染的特点、潜在危险因素及抗菌药物使用情况,制定高效、合理的预防及控制措施,以减少该院医院感染的发生及抗菌药物不合理使用。方法 2010年11月28日采用床旁调查与在架病历调查相结合的方法调查住院患者医院感染及抗菌药物使用情况。结果本次调查住院患者1543例,医院感染现患率1.94%,例次现患率为2.14%;医院感染重点科室为重症ICU(44.44%)、干一科(15.63%)和血液内科(9.38%);抗菌药物使用率46.73%,细菌送检率47.62%。基础疾病的复杂程度、侵入性操作、耐药菌传播可能是医院感染的危险因素。结论针对侵入性操作等医院感染危险因素制定个体化措施,减少重症ICU等重点科室医院感染的发生,是预防、降低该院医院感染发生率的关键。
