The role of clinical models in understanding the etiology of pneumonia

The etiology of pneumonia has changed since the beginning of the antibiotic era. Clinical and etiological classifications and protocols recommend immediate empiric antibio­tic treatment after diagnosing. However, recommendations for antibiotic treatment, on the one hand, and clinical misunderstanding of the etiology, on the other, gave rise to this review, reflecting the significance of clinical radiological and laboratory epidemiological models in detecting the etiology of pneumonia. We conducted a systematic review of domestic and English-language literature on the etiology of pneumonia. We reviewed articles on the etiology of various forms of pneumonia. We have studied many cases as well as the works that are cited and found as a result of the search.
