A cross-sectional study was conducted to assess the frequencies and
characteristics of occupational exposures among medical and nursing students at a
Brazilian public university, in addition to their prevention and post-exposure
behavior. During the second semester of 2010, a self-administered semi-structured
questionnaire was completed by 253/320 (79.1%) medical students of the clinical
course and 149/200 (74.5%) nursing students who were already performing practical
activities. Among medical students, 53 (20.9%) suffered 73 injuries, which mainly
occurred while performing extra-curricular activities (32.9%), with cutting and
piercing objects (56.2%), in the emergency room (39.7%), and as a result of lack of
technical preparation or distraction (54.8%). Among nursing students, 27 (18.1%)
suffered 37 injuries, which mainly occurred with hollow needles (67.6%) in the
operating room or wards (72.2%), and as a result of lack of technical preparation or
distraction (62.1%). Among medical and nursing students, respectively, 96.4% and 48%
were dissatisfied with the instructions on previously received exposure prevention;
48% and 18% did not always use personal protective equipment; 67.6% and 16.8%
recapped used needles; 49.3% and 35.1% did not bother to find out the source
patient's serological results post-exposure; and 1.4% and 18.9% officially reported
injuries. In conclusion, this study found high frequencies of exposures among the
assessed students, inadequate practices in prevention and post-exposure, and,
consequently, the need for training in “standard precautions” to prevent such
exposures.
