Objective:

to verify the association between recurrence of accidents with biological materials and the profile of the workers of Health Institutions.

Methods:

descriptive-analytical, cross-sectional, quantitative, performed in the Specialized Assistance Service, with 73 workers from health institutions that suffered an accident with material biological. A questionnaire with characteristics related to work and accidents was used, which were analyzed through descriptive and inferential statistics.

Results:

the variables age, time of action, weekly workload and work unit were associated to recurrence of accidents (p <0.05). More than once workers were injured more than 41 years old, with more experience and less than 40 hours a week. The prevalence of accidents increased by 11% (RP: 1.11) month/work, with reexposure being 66% lower (PR: 0.24) for the workload between 40-59hs.

Conclusions:

the results suggest that the recurrence of accidents may be related to the greater time of professional experience and the workload less than 40 hours per week.
