Abstract:
We realized a retrospective study of all the patients who developed a nosocomial meningitis after to admitted to the Intensive Care Unit of our hospital, during the last five years. Nosocomial meningitis was found in 3.29% of the neurologic patients. The most frequent causes of the meningitis was the external ventricular drainage (14.8%), post-neurosurgical (0.8%) and head injury (0.0007%). The causative bacterias were stafilococo, S. pneumoniae, K. pneunomiae and P. aeruginosa. The mortality was of the 39.06%.
Insights
Nosocomial meningitis, an infection acquired in hospitals, occurred in 3.29% of neurology patients. External ventricular drainage was the most common cause, with a high mortality rate of 39.06%.
Area of Science:
- Infectious Diseases
- Critical Care Medicine
- Neuroscience
Context:
- Retrospective analysis of patients admitted to the Intensive Care Unit (ICU) over five years.
- Focus on nosocomial meningitis, a hospital-acquired infection.
- Inclusion of neurologic patients to assess specific risk factors and outcomes.
Purpose:
- To determine the incidence and common causes of nosocomial meningitis in ICU patients.
- To identify the primary bacterial pathogens responsible for these infections.
- To evaluate the mortality rate associated with nosocomial meningitis in this cohort.
Summary:
- Nosocomial meningitis was diagnosed in 3.29% of neurologic patients.
- External ventricular drainage (14.8%) was the leading cause, followed by post-neurosurgical procedures (0.8%) and head injuries (0.0007%).
- Commonly identified bacteria included Staphylococcus, Streptococcus pneumoniae, Klebsiella pneumoniae, and Pseudomonas aeruginosa, with an overall mortality of 39.06%.
Impact:
- Highlights the significant risk of nosocomial meningitis in ICU patients, particularly those with external ventricular drains.
- Provides crucial data for developing targeted prevention and treatment strategies in critical care settings.
- Informs clinical practice regarding the management of meningitis in immunocompromised or critically ill patients.
