改善某市戒毒所内环境卫生对所内环境微生物及住院患者感染情况的影响

  目的  研究改善某市戒毒所内环境卫生后，监区内住院吸毒患者体液微生物及环境微生物培养阳性率有无改善。  方法  采集2018年2月至2021年12月某市戒毒所221名住院吸毒患者共计644份微生物培养标本，同时对同期戒毒所监区环境微生物采样，分析戒毒所环境卫生条件改善前后二者培养阳性率有无改变。  结果  环境改善后环境微生物培养阳性率显著低于环境改善前；监区环境卫生改善后，住院患者体液培养标本中肺炎克雷伯杆菌、抗酸杆菌检出率均降低，差异存在统计学意义（P < 0.05）；监区卫生环境改善后，环境微生物中金黄色葡萄球菌、大肠埃希菌、表皮葡萄球菌检出阳性率较改善前显著下降（P < 0.05）。  结论  对戒毒所监区环境卫生进行干预能有效降低戒毒所环境微生物及住院学员体液微生物培养阳性率。

Environmental Sanitation Improvement on Environmental Microbe and Infections of Inpatients

  Objective  To investigate the effect of the environmental sanitation improvement on the positive rate of environmental microbe culture and the body fluid culture of hospitalized drug abusers in an addiction treatment center.   Methods  From February 2018 to December 2021, a total of 644 microbial culture samples were collected from 221 hospitalized drug abusers in an addiction treatment center. Meanwhile, environmental microbe samples were collected from the prison area in the same center during the same period to analyze whether the positive culture rate of the two sets of samples changed after the improvement of environmental sanitation in this center.   Results  The positive rate of environmental microbe culture after environmental sanitation improvement was significantly lower than that before environmental sanitation improvement; After environmental sanitation was improved, the positive rate of Klebsiella pneumoniae and acid-fast bacillus culture was significantly lower than before （P < 0.05）; After environmental sanitation was improved, the positive culture rates of Staphylococcus aureus, Escherichia coli, and Staphylococcus epidermidis were markedly decreased （P < 0.05） than before.   Conclusions  Improvement of environmental sanitation in the prison area of an addiction treatment center can effectively reduce the positive culture rates of both environmental microbe and inpatients' body fluid samples.
