Improved mortality in gram-negative bacillary bacteremia.

J D McCue

    Archives of Internal Medicine
    |July 1, 1985
    PubMed
    Summary

    Gram-negative bacillary bacteremia increased by 15.9% from 1979-1982. Patient outcomes were primarily determined by the severity of underlying illnesses, not antibiotic regimens used.

    Area of Science:

    • Infectious Diseases
    • Clinical Microbiology
    • Hospital Epidemiology

    Background:

    • Gram-negative bacillary bacteremia is a significant hospital-acquired infection.
    • Understanding trends and prognostic factors is crucial for patient management.
    • Previous studies reported higher mortality rates associated with bacteremia.

    Purpose of the Study:

    • To analyze the incidence and mortality of gram-negative bacillary bacteremia.
    • To identify prognostic factors influencing bacteremia outcomes.
    • To evaluate the impact of empirical antibiotic regimens on mortality.

    Main Methods:

    • Retrospective analysis of bacteremia episodes over a four-year period (1979-1982).
    • Data collected from a 489-bed community teaching hospital.
    • Comparison of mortality rates across different patient groups and treatment strategies.

    Main Results:

    • A 15.9% increase in gram-negative bacillary bacteremia episodes was observed.
    • Overall mortality was 19.4%, but significantly lower (3.2%) for patients with nonfatal underlying illnesses.
    • Severity of underlying illness was the dominant prognostic factor, overshadowing antibiotic regimens.

    Conclusions:

    • The severity of underlying illness is the primary determinant of outcomes in gram-negative bacillary bacteremia.
    • Empirical antibiotic strategies, including combination therapy, did not significantly alter mortality rates.
    • Further research may be needed to optimize treatment for bacteremic patients with severe comorbidities.
