Resistance of Staphylococcus aureus (S. aureus) against common antibiotics has been increasing given the rampant use of antibiotics. Methicillin-resistant S. aureus (MRSA) is particularly important because it has been reported to present in hospital-acquired as well as community-acquired infections. Our aim was to study the types and subtypes of MRSA isolated from nasal swabs taken from volunteering dental school students and to assess and analyse the knowledge of dental health care workers (DHCWs) on MRSA and prevention of its infection.
A total of 100 participants, which included staff, students, and dental auxiliaries, from the School of Dental Sciences, Krishna Institute of Medical Sciences, Deemed to Be University, Karad, India, were included in the study which was conducted from June 2020 to 1 June 2021. All the participants completed a survey and underwent collection of nasal swabs. The samples were cultured and underwent microbiological and molecular analysis for MRSA. The questionnaire was sent out electronically via SurveyMonkey.
Sixty-three percent of the participants were female. The majority were undergraduate students (66%) and younger than 25 years (77%). The prevalence of MRSA in the sample was the MRSA type SCCmec type V (54.8%). The survey reports a lack of knowledge amongst dental students on MRSA and prevention of its infection. The majority (69%) of participants had not heard of MRSA infection and had inadequate knowledge of MRSA infection. Only 29% of the participants think that a healthy person may have MRSA without feeling ill. Eighty-five percent of the participants reported that they have written polices and guidelines to control MRSA. Eighty-five percent of the participants indicated that they are less confident in their knowledge on MRSA infection control protocols, and 94% mentioned that the dental clinics have written guidelines for hand hygiene.
DHCWs have limited knowledge of MRSA infection, emphasising the need for appropriate clinical training. Academic institutions should promote effective infection control training to protect students, faculty, and other employees.
由于抗生素的广泛使用，金黄色葡萄球菌（S. aureus）对常见抗生素的耐药性不断增加。耐甲氧西林金黄色葡萄球菌（MRSA）尤为重要，因为它已被报道存在于医院获得性和社区获得性感染中。我们的目的是研究从志愿牙科学院学生的鼻腔拭子中分离出的 MRSA 的类型和亚型，并评估和分析牙科保健工作者（DHCWs）对 MRSA 的认识以及预防其感染的知识。
2020 年 6 月至 2021 年 6 月，我们从印度 Karad 的 Krishna Institute of Medical Sciences，Deemed to Be University 的牙科学院共纳入 100 名参与者，包括工作人员、学生和牙科助理。所有参与者均完成了一项调查并接受了鼻腔拭子采集。对样本进行培养并进行微生物学和分子分析以检测 MRSA。问卷通过 SurveyMonkey 以电子方式发送。
63%的参与者为女性。大多数是本科生（66%），年龄在 25 岁以下（77%）。样本中 MRSA 的流行率为 MRSA 型 SCCmec 型 V（54.8%）。调查显示，牙科学生对 MRSA 及其感染预防知识不足。大多数（69%）参与者未听说过 MRSA 感染，对 MRSA 感染的了解不足。只有 29%的参与者认为健康人可能患有 MRSA 而没有不适感。85%的参与者报告说，他们有控制 MRSA 的政策和指南。85%的参与者表示，他们对 MRSA 感染控制方案的知识不太有信心，94%的参与者提到牙科诊所有手部卫生的书面指南。
DHCWs 对 MRSA 感染的了解有限，强调需要进行适当的临床培训。学术机构应推广有效的感染控制培训，以保护学生、教职员工和其他员工。
