目的了解某医疗机构医务人员胸牌及读卡器污染情况。方法随机选取该医疗机构ICU与普通病区医务人员胸牌、食堂读卡器及病区门禁系统读卡器共计86件,对其表面进行微生物采样及鉴定,并对56名医务人员胸牌的清洁及消毒情况进行询问。结果 86件物品微生物污染率为97.7%,共检出细菌264株,其中革兰阴性菌占9.1%,革兰阳性菌占58.0%,真菌占33.0%。同时检出了4株多重耐药鲍曼不动杆菌以及2株多重耐药铜绿假单胞菌,其中有5株来自于ICU医务人员胸牌,1株来自于食堂读卡器。重点监测耐药菌检出率为7.0%,重点部门医务人员胸牌重点监测耐药菌检出率为11.6%。80.4%的被调查者在携带胸牌离开工作场所时从来不会对其进行清洁或者消毒。结论医务人员尤其是ICU等重点部门的医务人员应加强对胸牌的清洁与消毒工作,同时医院感染管理部门也应加强对此工作的监督与管理。 Objective To understand the medical staff badge and card reader contamination in a medical institution. Methods A total of 86 IC card readers of medical institutions and medical staffs in ordinary ward, canteens card readers and ward access control system readers were selected randomly to sample and identify the surface of the ICU. 56 medical staffs Cleaning and disinfection of the inquiry. Results The microbial contamination rate of 86 articles was 97.7%. A total of 264 bacterial strains were detected, of which Gram-negative bacteria accounted for 9.1%, Gram-positive bacteria accounted for 58.0% and fungi accounted for 33.0%. Four multidrug-resistant Acinetobacter baumannii strains and two multi-drug resistant Pseudomonas aeruginosa strains were also detected, of which five were from the ICU medical staff breastplate and one was from a canteen reader. The detection rate of key drug-resistant bacteria was 7.0%, and the detection rate of key drug-resistant bacteria among key medical personnel in key departments was 11.6%. 80.4% of the respondents never carried out cleaning or disinfection when carrying the badge out of the workplace. Conclusion Medical personnel, especially those in key departments like ICU, should strengthen the cleaning and disinfection of breastplate, and hospital infection management department should also strengthen the supervision and management of this work.
