ABSTRACT
Purpose: Pneumonias, which are infections of the lung parenchyma, are divided into two groups as community acquired pneumonia (CAP) and hospital acquired pneumonia. CAP is very common and CAP can be mortal. Healthcare-Associated Pneumonia (HAP) is defined as pneumonia that develops in patients who have used antibiotic or hospitalization in the past three months and who are fed by a nasogastric tube. In recent studies, the term multidrug-resistant CAP has been used instead of HAP. In this study, it was aimed to compare the laboratory results, causative bacterial pathogens and fatality rates of CAP and multidrug-resistant CAP patients on the first day of hospitalization. Material and method: Patients with CAP and multi-drug-resistant CAP who were admitted to the Infectious Diseases and Clinical Microbiology Clinic between 09/01/2018-03/20/2020 were recruited. Results: 129 patients with CAP and 64 patients with multidrug-resistant CAP were studied. Underlying disease was found in 96.9% (62) patients in the multidrug-resistant CAP group and in 79.8% (103) patients in the CAP group. A significant difference was found between the two groups (p=0.003). 79.7% (51) patients in the multidrug-resistant CAP group and 19.4% (25) patients in the CAP group used antibiotics in the last three months. It was found to be significantly higher in the multidrug-resistant CAP group (p=0.000). Conclusion: The underlying disease and the use of antibiotics in the last three months increase the risk of developing multidrug-resistant CAP. Mortality rate was found to be higher in this patient group. In order to encounter less multidrug-resistant CAP problem, it is necessary to pay attention to the rules of rational use of antibiotics in medical practice. © 2022, Pamukkale University.
