Exposure to blood and body fluids for medical students during clerkship / 대한내과학회지

ABSTRACT

BACKGROUND/AIMS: Medical students face the threat of acquiring blood-borne infections such as HIV, Hepatitis B and Hepatitis C during their clinical activities in clerkship. This study determined the frequency of exposure and the risks of exposure to blood and body fluids among medical students. METHODS: An anonymous questionnaire was administrated to the 4th year medical students in a tertiary academy university hospital. RESULTS: The surveys were completed by 124 students (100% of the students). Seventy-one percent (88 cases) reported more than one time of exposure to blood or body fluids during the consecutive 2 years of clinical rotation. Single needle stick injury occurred for 19.3% of the students, both exposure to needle stick and splash occurred for 40.9% and single splash occurred for 39.8% of the 88 cases. Venipucture was the highest exposure event (50%), and the other causes were scrub (35.2%), bedside procedures (35.2%), arterial puncture (22.7%), lancet (13.6%), suture (5.7%) and others (8%). The emergency department had the highest exposures rate (80.7%), and this was followed by general surgery (33%), neurosurgery (8%), orthopedic surgery (8%), plastic surgery (6.8%), obstetrics-gynecology (5.7%) and others (10.1%). The major exposure sites in the hospital were the emergency room (81.8%), operation room (38.6%), intensive care unit (8%), general ward (6.8%) and others (2.3%). Only nineteen cases (21.6%) of hospital exposure were reported to the appropriate medical personnel. CONCLUSIONS: This study shows medical students have the potential risk of health care related infection when they are exposed to many patients in the emergency department without a supervisor being present. To avoid the occurrence of these problems, preventive education, and particularly the practice of universal precaution, should be taken by the medical students before beginning their clinical activity.
