This study analyzed 461 septicemia cases from 1985, identifying common bacterial causes and infection sites. Pulmonary septicemias showed the highest mortality, while osseous and cardiac infections most frequently required combined antibiotic therapy.

Area of Science:

  • Infectious Diseases
  • Microbiology
  • Public Health

Background:

  • Septicemia remains a significant cause of morbidity and mortality.
  • Understanding causative organisms and common infection sites is crucial for effective treatment.
  • An informatics system allowed for collaborative data collection across multiple institutions.

Purpose of the Study:

  • To analyze the epidemiology of septicemia, including causative agents and primary infection sites.
  • To investigate the relationship between infection site, causative organism, and patient outcomes.
  • To evaluate antibiotic treatment strategies for different types of septicemia.

Main Methods:

  • Retrospective analysis of 461 septicemia cases collected in 1985 from 17 university hospitals.

  • Data collected via an informatics system, detailing septic localizations, causative organisms, and outcomes.
  • Statistical analysis to determine frequencies, correlations, and mortality rates.

    • Main Results:

    • Urologic and pulmonary sites were the most frequent septicemia localizations.
    • Gram-positive cocci (Staphylococcus, Streptococcus) and Gram-negative bacilli (Escherichia coli) were the primary causative organisms.
    • Pulmonary septicemias had the highest mortality rate (35%); osseous and cardiac infections most frequently required combination antibiotic therapy.

    Conclusions:

    • Septicemia epidemiology varies by causative organism and infection site.
    • Prompt identification and appropriate antibiotic treatment are critical for improving patient outcomes.
    • Further research into optimal antibiotic regimens for severe septicemias is warranted.
