Needlestick injuries and other occupational exposures to body fluids amongst employees and medical students of a German university: incidence and follow-up

SummaryThe aim of this study was to obtain data concerning the incidence, reporting and follow-up of occupational exposure to blood or other body fluids (OEB). A questionnaire was distributed to employees and medical students (N = 787) and official reports of OEB during the year 2003 (N = 203) and their consequent follow-up (N = 100) were evaluated. The percentages of needlestick injuries were 29.5% for students and 22.5% for employees. Incidence rates per 1000 employee days were 0.61 for needlestick injuries or sharp object injuries and 0.27 for mucocutaneous exposure to body fluids. The mean rate of underreporting was approximately 45%. Contrary to expectations, only 4.3% of nurses and 3.9% of doctors officially reported an OEB in 2003. The number of persons who did not attend for a serological test increased during the follow-up period. Considering all documented test results, 35 out of 100 affected persons were lost to follow-up due to default of appearance. As a consequence, the employer should provide safety devices and enforce didactical interventions with practical training and incident reporting. Periodical occupational health medicals, including serological testing, should be mandatory for all employees, including medical students and student nurses. To increase compliance after OEB, a short follow-up period using improved laboratory tests requires further discussion.
