Bacteremia in a community hospital: spectrum and mortality

Abstract

The problem of bacteremia was studied at a 500-bed community hospital during 1974-1975. All patients with positive blood cultures for clinically significant organisms were analyzed with respect to age, sex, host factors, type, dose and time of institution of therapy with antibiotics, and mortality. Of 142 episodes of bacteremia, outcome according to underlying host factors showed that 12/15 died in the rapidly fatal group, 12/24 died in the ultimately fatal group and in the nonfatal group 25/103 died. Mortality for gram-positive bacteremia was 37% (16/43) vs. 13% (7/54) for gram-negative bacteremia in the nonfatal group. In addition to underlying host factors, inappropriate antibiotic therapy also contributed to higher mortality in patients with gram-negative bacteremia.
