Follow-up study for the analysis of needlestick injuries (NSI) among students of human medicine in consideration of the regulations of the TRBA 250

Project No. FF-FP 0287




Systematic surveys during the clinical part of the studies of human medicine at the University of Duesseldorf are first of all to provide an inventory as to how often and in which activities needlestick injuries (NSI) occur among students. Furthermore, the positive results obtained through the use of safety syringes are to be evaluated. Suggestions for additional possibilities of prevention and training measures are to be developed. Among other things, a training video including training transparencies is devised for the medical sector in the context of the project. These didactically optimized materials are to be evaluated by the students.


Students of human medicine at the Heinrich-Heine-University of Duesseldorf are surveyed in detail about possible NSI and other injuries related to their professional activity. The surveys are conducted at different points of time during the clinical part of their studies, using a specially developed survey questionnaire to document NSI that might have occurred. The collected data is to be as compatible as possible with the already existing EPINet-database (Exposure Prevention Information Network, database of Wuppertal University) and to allow for a completion of the database, since EPINet does not yet contain any data about students.

The first survey takes place at the beginning of the clinical part in the context of the obligatory briefing on occupational safety by the Institute of Occupational and Social Medicine. The second survey is conducted towards the end of the clinical part of the studies, when the students attend the course "Occupational Medicine and Social Medicine" (5th or 6th clinical semester). Here, attendance is also obligatory. Thus, it is possible to observe the entire year of students as one cohort and to capture the frequency of needlestick injuries among students of human medicine (groups 1-3, n ~ 400, estimation of prevalence and incidence).

Furthermore, within the period of the study those students are surveyed who have already gained clinical experience in block E/F (last clinical year of study) but of whom no initial systematic collection is available (groups 4-7, n ~ 500, estimation of prevalence).
In addition to the surveys, moderated discussion groups on the issue of "health hazards during studies" are established in the context of the course "Occupational Medicine and Social Medicine". In these forums technical, psychological, social and other potential causes of hazards are documented and possible approaches to a solution are worked out.

The instructors´ observations and experiences in the cooperating surgeries and clinics form a third pillar of data. This information is gathered in the context of interviews and observation protocols.
