[Characteristics of nosocomial pneumonia]
Abstract:
284 patients with pneumonia treated in non-invasive chest wards were analysed in a prospective study. Out of 284 cases 26 proved to be nosocomial pneumonias. Older age, chronic non specific lung diseases, malignancies, peptic ulcus, chronic alcoholism as risk factors for nosocomial pneumonia should be taken into consideration. The pathogen agent was clearly identified in four cases, meanwhile the pathogenity of the agents was suspected at seven patients. By distribution of all pathogens the widely known bacteria are responsible for nosocomial pneumonia were less than one third of cases (in three cases Staphylococcus aureus, in one-one case E. coli and Enterobacter). The possible causes of their observation were analysed. Out of the 15 pathogens Gram-negative bacilli were found in six cases only. Authors suggest to use this observation at the rational choice of empiric treatment.
Insights
Nosocomial pneumonia, acquired in hospitals, affects a small percentage of patients. Risk factors include older age and chronic lung disease, with common bacteria less frequently identified as the cause.
Area of Science:
- Medicine
- Infectious Diseases
- Pulmonology
Context:
- Prospective study analyzing 284 pneumonia patients in non-invasive chest wards.
- Identified 26 cases (9.2%) as nosocomial pneumonia.
- Focus on risk factors and causative agents of hospital-acquired pneumonia.
Purpose:
- To analyze the incidence, risk factors, and causative agents of nosocomial pneumonia.
- To inform empirical treatment strategies for hospital-acquired pneumonia.
Summary:
- Older age, chronic lung diseases, malignancies, peptic ulcers, and chronic alcoholism are significant risk factors for nosocomial pneumonia.
- Common bacteria like Staphylococcus aureus, E. coli, and Enterobacter accounted for less than one-third of identified pathogens.
- Gram-negative bacilli were identified in only six out of 15 pathogen cases.
Impact:
- Highlights the importance of considering specific risk factors in susceptible patients.
- Suggests that widely known bacteria may not always be the primary cause of nosocomial pneumonia.
- Provides data to guide the rational selection of empiric antibiotic treatment for hospital-acquired pneumonia.
