title: Occupational exposure to blood borne pathogens among healthcare workers: a cross-sectional study of a registry in Colombia.
abstract: BACKGROUND
  Occupational exposure to blood borne pathogens caused by percutaneous injuries or mucosal contamination is frequent among Healthcare Workers (HCW).
  
  
  METHODS
  A cross-sectional analysis of HCW with an occupational exposure to blood reported to professional risk insurance agencies between 2009 and 2014 was performed. Comparisons between groups according to exposure level (mild, moderate, and severe) were evaluated.
  
  
  RESULTS
  Two thousand, four hundred three reports were classified according exposure as mild 2.7 %, moderate 74.8 %, severe 21.9 %. Factors related: health sciences student with mild exposure events [adjusted odds ratio (AOR) 11.91, 95 % CI 5.13-27.61, p < 0.00001], and physician with moderate exposure events (AOR 1.90, 95 % CI 1.17-3.07, p = 0.009). Factors inversely related: physician with severe exposure events (AOR 0.54, 95 % CI 0.32-0.91, p = 0.02) and health sciences student with moderate exposure events (AOR 0.08, 95 % CI 0.04-0.15, p < 0.00001). It was found an important relationship between severe events with infectious diseases specialist assessment, and follow-up adherence. Additionally, a case of Human Immunodeficiency Virus seroconversion was presented (0.0004 %), no other seroconversions were observed.
  
  
  CONCLUSIONS
  Occupational exposure events must be managed according to established protocols, but adherence failure was evident with the exception of severe exposure cases. Thus, interventions to enhance occupational safety are required. Occupation must be considered as a risk factor during initial assessment of events.
