[Sepsis at an internal medicine department].

185 cases of bacteremia admitted at the internal medicine department of "C.S. Virgen de la Arrixaga" in Murcia from 1977 to 1986, were studied retrospectively. The common infection was significantly associated to Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus A group and Neisseria meningitidis and the nosocomial infection was associated to Klebsiella Pneumoniae, Serratia Marcescens y Pseudomonas aeruginosa, Staphylococcus epidermidis and Enterobacter. We did not find significant differences between the common and nosocomial infection caused by E. Coli and Proteus mirabilis. These factors were associated to an increase of mortality: age greater than 40 years, nosocomial infection, Pseudomonas aeruginosa, other associated rapidly lethal diseases, acute clinical state at the beginning of bacteremia, shock and non-correct antibiotic therapy.
