Abstract:
A fever of nosocomial origin is defined as one which develops three or more days after a patient has been admitted to the hospital. It occurs in four patient groups: (1) those incubating an infection on admission; (2) those whose fever is related to an underlying, non-infectious disease; (3) those who develop an endogenous febrile process; and (4) those who acquire an infection of other febrile process. Diagnostic considerations are reviewed for eight major classes of fevers of nosocomial origin. Special attention must be paid to empiric therapy and pathogens in the immunocompromised host.
Insights
Nosocomial fever, developing three days post-hospital admission, presents in four patient groups. This review covers diagnostic considerations for eight major classes, emphasizing immunocompromised hosts.
Area of Science:
- Infectious Diseases
- Hospital Epidemiology
- Clinical Medicine
Background:
- Nosocomial fever is defined as a fever developing ≥3 days after hospital admission.
- It encompasses infections acquired during hospitalization.
- Understanding its origins is crucial for patient care.
Purpose of the Study:
- To define nosocomial fever and its common patient groups.
- To review diagnostic considerations for major classes of nosocomial fever.
- To highlight critical aspects of management, especially in immunocompromised patients.
Main Methods:
- Literature review of nosocomial fever definitions and classifications.
- Analysis of diagnostic challenges across different fever etiologies.
- Emphasis on empiric therapy and pathogen identification.
Main Results:
- Nosocomial fever occurs in four primary patient categories.
- Eight major classes of nosocomial fever are identified.
- Diagnostic strategies vary based on the underlying cause.
Conclusions:
- Accurate diagnosis of nosocomial fever is essential for effective treatment.
- Special attention is required for immunocompromised patients.
- Timely and appropriate management of nosocomial infections improves patient outcomes.
