Abstract

Background: Hospital-acquired infections have been a hot topic in the healthcare industry in recent years. According to statistics, the rate of hospital-acquired infections accounts for approximately 5-10% in developed countries and 15-20% in developing countries. The consequences of hospital-acquired infections have serious implications for patients, their families, and society as a whole. They can worsen the patient's condition, increase mortality rates, raise healthcare costs, and negatively impact the reputation of healthcare facilities while placing an additional burden on healthcare systems. The causes of hospital-acquired infections often originate from polluted environments, contagious diseases, and improper instrument handling, with transmission through the hands of healthcare workers being a leading contributing factor. However, hospitals typically only conduct surveys on their medical staff, overlooking a significant group of individuals working in various departments – the interns and medical students. This can potentially pose a significant source of infection as these individuals may lack full awareness of hand hygiene practices and have limited practical experience in biosafety, making them susceptible to transmitting disease agents to patients and medical equipment. Therefore, conducting microbiological assessments on the hands of medical students interning at hospitals is also of great importance, directly influencing infection prevention efforts in healthcare settings. This practice can help evaluate the awareness and handwashing techniques of medical students, contributing to the development of hospital internship programs that enhance infection control and biosafety practices among students. Materials and methods: The cross-sectional design depicts an analysis of 82 undergraduate students currently undergoing internship at the university hospital of Dong Nai University of Technology from January 2023 to June 2023. Results: The research conducted on 82 interns at the hospital revealed that prior to hand washing, 71 (86.6%) of the interns' hands carried between 1-4 types of bacteria. After hand washing, the percentage decreased to 35 (42.7%) hands with bacteria. The frequency of Staphylococcus aureus decreased from 24 cases (29.3%) to 6 cases (7.3%); Klebsiella pneumoniae decreased from 7 cases (8.5%) to 2 cases (2.4%); Coagulase-negative Staphylococci decreased from 69 cases (84.1%) to 30 cases (36.6%); Escherichia coli decreased from 5 cases (6.1%) to 0 cases (0%); Gram-negative rods decreased from 9 cases (11%) to 8 cases (9.8%); Bacillus decreased from 10 cases (12.2%) to 6 cases (7.2%); Fungi decreased from 6 cases (7.3%) to 3 cases (3.7%). Conclusion: Hand hygiene; Students; Dong Nai University of Technology.
