Background:
Community acquired bacterial meningitis (CABM) is a condition associated with significant morbidity and mortality. Treatment delay remains an area of concern and might be improved by awareness of meningitis among health care professionals.
Methods:
Retrospective observational study of patients with CABM between 2016 and 2021 in Eastern Denmark with a population of 2,700,000. Data was extracted from electronic health records. Treatment delay and mortality was analyzed using multivariate logistic regression and expressed as odds ratio (OR) with 95% confidence intervals (CI).
Results:
Of 369 patients 226 (61%) had treatment delayed more than 2 hours. Old age (OR 2.42, CI 1.22;4.77), comorbidity (OR 1.30, CI 1.00;1.70), suspicion of other infections than meningitis (OR 65.93, CI 20.68;210.20), stroke (OR 7.24, CI 3.11;16.86) and other diagnoses (OR 13.00, CI 5.07;33.31) were associated with delayed treatment. Treatment delay was associated with increased 30-day mortality (OR 3.07, 95% CI 1.09;8.67). Most of the treatment delay (82%) was due lack of suspicion of CABM.
Conclusions:
Treatment delay is a common problem associated with 30-day mortality in CABM. Awareness of CABM in undiagnosed patients is vital to achieve timely initiation of appropriate treatment. Special care should be shown for patients suspected of stroke or other infections.

Age plays a significant role due to differences in body composition among different age groups. Infants, for instance, have a higher proportion of total body water and lower albumin levels, a protein that binds drugs in the bloodstream. This unique composition in infants enhances the...

Bacterial Pneumonia Treatment
For bacterial pneumonia, antibiotics serve as the cornerstone of therapy. Initial treatment often begins with empirical antibiotics, tailored to the anticipated causative organism and adjusted based on culture results. Key antibiotic choices include:
