■医院环境是病原微生物的利基,因此,人们一直在努力确定导致临床感染的微生物病原体传播的潜在模式。
■这项研究的目的是对贝宁大学教学医院(UBTH)的临床医生使用的听诊器进行微生物学检查,尼日利亚。
■共106名临床医生使用用生理盐水润湿的棉签清洁听诊器。这包括两个听筒以及隔膜(每个听诊器三个样品)。然后将样品送到UBTH的医学微生物学实验室,并立即按照标准指南进行处理。随后确定了紧急殖民地,并进行抗菌药物敏感性试验。
■共回收114株(35.8%)细菌分离株,包括金黄色葡萄球菌(S.金黄色葡萄球菌)(33.3%),凝固酶阴性葡萄球菌(CoNS)(33.3%),芽孢杆菌。(22.8%),不动杆菌属。(5.3%),大肠杆菌(E.大肠杆菌)(1.8%)和克雷伯菌属。(3.5%)。隔膜的耐甲氧西林金黄色葡萄球菌(MRSA)和CoNS(17.9%)的产量最高。年龄(P=0.0387)和临床医生的干部(P=0.0043)是污染的危险因素,而从未清洁听诊器(P=0.0044)或仅清洁听筒(P=0.0001)的临床医生的听诊器受污染程度更高。
■贝宁市临床医生使用的听诊器的污染率为56.6%。有必要为临床实践中的所有干部建立适当的听诊器清洁实践,以最大程度地减少对患者和医护人员(HCW)的健康风险。
UNASSIGNED: The hospital environment serves as a niche for pathogenic microorganisms, so efforts are constantly being made to identify the potential mode of microbial pathogen transmission causing clinical infections.
UNASSIGNED: The aim of this study was to microbiologically examine the stethoscopes used by clinicians at the University of Benin Teaching Hospital (UBTH) in Benin, Nigeria.
UNASSIGNED: A total of 106 clinicians\' stethoscopes were cleaned using cotton-tipped swabs dampened with normal saline. This included both earpieces along with the diaphragm (three samples per stethoscope). The samples were then sent to the Medical Microbiology Laboratory of UBTH and processed immediately as per the standard guidelines. The emergent colonies were subsequently identified, and antimicrobial susceptibility tests were performed.
UNASSIGNED: A total of 114 (35.8%) bacterial isolates were recovered, including Staphylococcus aureus (S. aureus) (33.3%), coagulase-negative staphylococci (CoNS) (33.3%), Bacillus spp. (22.8%), Acinetobacter spp. (5.3%), Escherichia coli (E. coli) (1.8%) and Klebsiella spp. (3.5%). Diaphragms had the highest yield of methicillin-resistant S. aureus (MRSA) (46.2%) and CoNS (17.9%). Age (P = 0.0387) and cadre of clinician (P = 0.0043) were risk factors for contamination, whereas clinicians who never cleaned their stethoscopes (P = 0.0044) or cleaned only the earpieces (P = 0.0001) had more contaminated stethoscopes.
UNASSIGNED: The contamination rate of stethoscopes used by clinicians in Benin City was 56.6%. There is a need to establish proper stethoscope cleaning practices for all cadres of personnel in clinical practice to minimise health risks to patients and healthcare workers (HCW).
