[Analysis criteria's influence on incidence and factors associated tuberculin conversion in health care workers].
BACKGROUND
To know from two different criteria, CDC's and Spanish national consensus (NC), the tuberculin conversion rate and the factors associated to this phenomenon.


METHODS
A retrospective cohort study was designed over 475 health care workers. Risk factors were identified by using a Cox's proportional hazards model for each criteria.


RESULTS
Not being vaccinated with BCG appears to be a risk factor in NC model 5.37 (CI 95%: 2.21-13.00) and does not in CDC. There was a difference of 45% between both incidence density rates.


CONCLUSIONS
We did not find a total concordance between the results from the two models.
