Abstract :

A prospective and observational study of 200 adult patients with symptoms, signs suggestive of and radiological evidence of pneumonia, admitted in Acute Medical care unit during one year period. Pregnant women and Post operative patients were excluded. After obtaining a detailed history, a complete general physical and systemic examination, patients were subjected to relevant investigations. Pleural fluid analysis, throat swab c/s, Computerised Tomography of thorax, onchoscopy with Broncho alveolar lavage (BAL) were done if necessary. Majority were males (57%) . Mean age of the study group was 50.5 ± 2.38. Risk factors for developing pneumonia were diabetes, smoking, alcoholism, hematological disorders and connective tissue disorders . Microbiological yield was present in 78 cases (39%) and was more from onchosecretions (Tracheal aspirate/Broncho Alveolar Lavage). Gram negative organisms were more common. Klebsiella and E.coli were the common organisms. By serology, Scrub typhus was common and among viral, H1N1 was more common. Chest radiograph showed predominantly bilateral lower zone involvement with alveolar pattern. CT scan had a better delineation with diagnostic accuracy. Mortality (19%) was more in patients with multiorgan dysfunction, ARDS .
