Abstract:
Background: Postoperative meningitis (POM) is the most dreaded cause of morbidity and mortality in neurosurgery patients. This study aimed to identify incidence and mortality rate as well as related factors to outcome in patients with POM. Methods: This descriptive longitudinal study conducted on patients with POM in duration of 2 years. Incidence and mortality rates as well as related factors were studied. Results: The incidence and mortality rates of POM was 8.9% and 50%, respectively. There were statistically significant association between male gender, as well as having mechanical ventilation, and death outcome in univariable analysis. In addition, in multivariable logistic regression analysis, length of intensive care unit (ICU) stay of more than 7 days [Odds ratio (OR): 1.2, confidence interval of 95% (95%CI): 1.02-6.2), mechanical ventilation (OR: 1.1, 95%CI: 1.05-5.1], positive cerebrospinal fluid (CSF) culture (OR: 2.4, 95%CI: 1.9-4.08) were predicting factors to death outcome. Finally, we found an inverse relationship between survival function and length of ICU stay in patients with POM. Conclusion: According to the high rates of incidence and mortality due to POM in this study, preventive studies to decrease this dreaded cause of morbidity and mortality in neurosurgery patients should be the planned.
Insights
Postoperative meningitis (POM) affects 8.9% of neurosurgery patients, with a 50% mortality rate. Key risk factors for death include mechanical ventilation and positive cerebrospinal fluid cultures.
Area of Science:
- Neurosurgery
- Infectious Diseases
- Critical Care Medicine
Background:
- Postoperative meningitis (POM) is a significant cause of death in neurosurgery.
- Identifying incidence, mortality, and risk factors is crucial for patient outcomes.
Purpose of the Study:
- To determine the incidence and mortality rates of POM.
- To identify factors associated with mortality in POM patients.
Main Methods:
- A 2-year descriptive longitudinal study.
- Analysis of incidence, mortality, and predictive factors for death.
Main Results:
- POM incidence was 8.9% with a 50% mortality rate.
- Factors predicting death included mechanical ventilation, positive CSF culture, and prolonged ICU stay (>7 days).
- Survival decreased with longer ICU stays.
Conclusions:
- High POM incidence and mortality necessitate preventative strategies.
- Targeted interventions are needed to reduce POM-related morbidity and mortality in neurosurgery.
