Abstract

Background: Bacterial pneumonia remains a leading cause of morbidity and mortality worldwide, characterized by inflammation of the pulmonary parenchyma due to bacterial pathogens. It is classified into community-acquired (CAP), hospital-acquired (HAP), healthcare-associated (HCAP), and ventilator-associated (VAP) pneumonia, each with distinct etiologies and management strategies. This article provides a comprehensive review of bacterial pneumonia, focusing on etiology, diagnostic approaches, risk factors, and Nursing management to optimize patient outcomes. Methods: The study synthesizes clinical, laboratory, and radiological diagnostic methods, including chest X-rays, sputum cultures, and biomarkers. Management strategies emphasize empirical antibiotic therapy, risk stratification (e.g., CURB-65), and tailored treatment based on pathogen identification. Results: Streptococcus pneumoniae is the most common CAP pathogen, while Pseudomonas aeruginosa and MRSA dominate HAP/VAP. Early antibiotic initiation improves outcomes, with macrolides, fluoroquinolones, and beta-lactams as first-line agents. Vaccination, smoking cessation, and multidisciplinary care reduce complications and mortality. Conclusion: Bacterial pneumonia requires prompt diagnosis and tailored therapy. Interprofessional collaboration enhances recovery, while preventive measures like vaccinations mitigate recurrence. Future research should focus on antibiotic resistance and novel diagnostics.

Keywords: Bacterial pneumonia, Streptococcus pneumoniae, CURB-65, antibiotic therapy, vaccination, multidisciplinary care.
