A systematic review published in the NEJM Evidence journal, coordinated by the D'Or Institute for Research and Education (IDOR), assessed the outcomes of adults with community-acquired pneumonia (CAP) admitted to intensive care units (ICUs) in middle-income countries. The analysis, which included 52 studies and approximately 48,707 patients, revealed an alarming overall mortality rate of 37.1%, significantly higher than the 16-26% range found in high-income countries. Among patients requiring mechanical ventilation, mortality soared to 59.3%. The study underscores that systemic healthcare disparities, rather than just patient severity, play a critical role in these outcomes. Factors such as delayed healthcare access, limited resources, and a lack of standardized protocols were identified as contributing to the high mortality rates. Notably, the research highlighted a major gap in data from low-income countries, which limits understanding of pneumonia's burden in vulnerable settings. The authors advocate for strengthening healthcare systems and improving early access to intensive care, emphasizing the need for further research to inform healthcare policies and resource allocation.
