Nosocomial pneumonia in medico-surgical intensive care unit
1Department of Diagnostic Radiology, College of Medicine, University of Ulsan, Songpa-Ku, Seoul, Korea.
Abstract:
Cases of hospital acquired pneumonia occurring during the 1st 12 months of Medico-Surgical ICU (Intensive care unit, MSICU) in operation were evaluated retrospectively to determine its incidence, common causative pathogens, outcome and radiological patterns with the new hospital setting providing a unique relatively aseptic environment. Among the 920 admitted patients, 73 episodes of nosocomial pneumonia on 63 patients were identified and the incidence rate was 7%. The most common pathogens were Pseudomonas. Staphylococcus, Serratia, and Enterobacter in the order of frequency of occurrence, and the gram-negative pathogens comprised 70%. Nosocomial pneumonia was more common after use of antibiotics due to such pathogens as Enterobacter, Acinetobacter, and Candida which caused poor outcome. Enterobacter had the greatest tendency to be related with poor outcome and Serratia the least. Overall mortality was 25%. Bronchopneumonia was the most common type of pneumonia caused by any pathogen except Acinetobacter which caused a mixed type of nosocomial pneumonia.
Insights
This study found a 7% incidence of hospital-acquired pneumonia in a new Medico-Surgical Intensive Care Unit (MSICU). Pseudomonas and other gram-negative bacteria were common pathogens, with Enterobacter linked to poorer outcomes and 25% overall mortality.
Area of Science:
- Critical Care Medicine
- Infectious Diseases
- Hospital Epidemiology
Background:
- Hospital-acquired pneumonia (HAP) is a significant concern in intensive care settings.
- Evaluating HAP in a new, relatively aseptic Medico-Surgical Intensive Care Unit (MSICU) provides unique insights.
Purpose of the Study:
- To determine the incidence, causative pathogens, outcomes, and radiological patterns of HAP within the first year of MSICU operation.
- To assess the impact of the new hospital environment on HAP epidemiology.
Main Methods:
- Retrospective analysis of 920 patients admitted to the MSICU during its initial 12 months.
- Identification of nosocomial pneumonia episodes, causative pathogens, and patient outcomes.
- Radiological pattern assessment for different pathogens.
Main Results:
- An incidence rate of 7% for nosocomial pneumonia was observed (73 episodes in 63 patients).
- Common pathogens included Pseudomonas, Staphylococcus, Serratia, and Enterobacter (70% gram-negative).
- Enterobacter, Acinetobacter, and Candida were associated with poor outcomes; overall mortality was 25%.
Conclusions:
- The incidence of HAP in the new MSICU was 7%, with gram-negative bacteria dominating.
- Specific pathogens like Enterobacter significantly impacted patient outcomes.
- Bronchopneumonia was the predominant radiological pattern, except for Acinetobacter which caused mixed patterns.
