目的了解某院住院患者抗菌药物使用及病原学送检情况,为制定持续改进措施提供依据。方法对2015年8月6日的1674例住院患者抗菌药物使用及病原学送检情况进行横断面调查。结果 1 674例患者中,621例使用抗菌药物,调查日抗菌药物使用率为37.10%,其中治疗用药者所占比例为46.54%,预防用药者所占比例为38.00%,治疗+预防用药者所占比例为15.46%。治疗性用药患者病原学标本送检率为19.48%,Ⅰ类切口抗菌药物预防使用率为72.38%。本次调查共检出病原菌48株,感染病原菌以革兰阴性菌为主,占70.83%。排前三位的病原菌依次为大肠埃希菌﹑肺炎克雷伯菌和鲍曼不动杆菌。结论该院抗菌药物使用率虽符合国家相关标准要求,但Ⅰ类切口手术预防使用抗菌药物比例偏高,应提高病原学送检率,进一步规范抗菌药物的使用。
Objective To understand the use of antimicrobial agents and the etiological examination of inpatients in a hospital and provide the basis for making continuous improvement measures. Methods A total of 1,674 inpatients were investigated for antimicrobial use and etiology on August 6, 2015. Results Among the 674 patients, 621 were antibacterials, and the antibacterials utilization rate was 37.10% on the survey day, among which 46.54% were treated and 38.00% were prophylactic, while those treated and prophylactic Accounting for 15.46%. The therapeutic rate of etiological specimens was 19.48% in patients receiving therapeutic drugs and 72.38% in patients receiving type Ⅰ incisional antibiotics. A total of 48 pathogens were detected in this survey. Gram-negative bacteria were the main pathogens in the survey, accounting for 70.83%. The top three pathogenic bacteria followed by Escherichia coli, Klebsiella pneumoniae and Acinetobacter baumannii. Conclusion Although the usage of antibacterials in this hospital accords with the requirements of relevant national standards, the proportion of antibacterials used in class Ⅰ incision surgeries is relatively high. The rate of etiological examination should be increased to further standardize the use of antibacterials.
