Risk factors for nosocomial intensive care infection: a long-term prospective analysis

Area of Science:

• Intensive Care Medicine
• Infectious Disease Epidemiology
• Trauma Surgery

Background:

• Identifying risk factors for hospital-acquired infections (nosocomial infections) in intensive care settings is crucial for effective resource allocation.
• Understanding these factors aids in developing targeted prevention strategies.

Purpose of the Study:

• To identify key risk factors for nosocomial infections within a surgical-medical intensive care unit.
• To provide evidence-based recommendations for resource allocation in infection prevention.

Main Methods:

• A long-term prospective incidence study was conducted in a university hospital's surgical-medical intensive care unit.
• Data were collected over four years, observing 562 patients with extended stays (>48 hours).

Main Results:

• The overall nosocomial infection rate was 14 per 100 admissions, with infections prolonging hospital stays and doubling mortality risk.
• Key risk factors identified included central venous catheter use, mechanical ventilation, pleural drainage, and trauma with open fractures.
• Trauma patients, particularly those with open fractures, showed a significantly increased risk of infection, primarily wound infections.

Conclusions:

• Patients with trauma and open fractures are at the highest risk for nosocomial infections, irrespective of disease severity.
• Preventive resources should be strategically allocated to mitigate infection risks in this high-risk patient group.
