[Hospital sepsis and pre-existing disease]

By retrospective study in a fifteen period from 1990 to 2004 to research if a pre-existential disease influences the appearance of gram-positive and gram-negative clear determinated hospital sepsis among 200 septic patients, selected by a random method and with clinic-laboratory signs of sepsis and monomicrobial blood culture.

Specimen of septic patients analysed in relation to the patient condition and statistically processed using chi2 test and contigential coefficient C.

We received statistically significant results when we have correlated gram-negative hospital sepsis and pre-existential disease, until this significancy was absent in gram-positive hospital sepsis.

Pre-existential disease can indicate sepsis, the place of acquisition and etiology.
