[Biological fluid-related accidents amongst professionals working in clinical laboratories in Maracaibo, Venezuela].

OBJECTIVE

Determining the occupational exposure to biological fluids of medical technicians working in public clinical laboratories caused by accidental percutaneous contact, associated factors and compliance with post-exposure biological measures.

METHODS

This was a descriptive cross-sectional study. The sample consisted of 156 medical technicians assigned to clinical laboratories in the metropolitan area of Zulia state in Venezuela. Data was collected by applying an instrument for exploring exposure and related factors, as well as compliance with established post-biological exposure measures.

RESULTS

There was evidence of exposure caused by percutaneous accidents, mainly represented by a moderate level of needle-pricks and cuts (2-3.99 mean). There was a moderate level of factors regarding percutaneous injury in the hands and fingers associated with hollow needles, blood and blood products and superficial severity in sample taking and processing areas when recapping needles or handling sharp or cutting objects. A medium level (2-3.99 mean) of compliance was obtained for post-exposure handling. A significant correlation was found (p<001) between percutaneous exposure and level of compliance with post-exposure management.

CONCLUSION

The magnitude and characteristics of exposure to biological fluids detected in this work represents a problematic situation which can affect staff health and must be approached by institutions to ensure effective prevention management and risk control.
