Background: Theaim of this study is to investigate whether sputum culture results (treatmentrevision according to culture results) have an effect on the duration ofhospitalization in patients who were followed up with the diagnosis ofbronchiectasis in our clinic.Materials and Methods: Thelaboratory and radiological data of 23 patients who were followed up with thediagnosis of bronchiectasis in the chest diseases clinic between January2018-December 2018 were analyzed retrospectively. Demographic features, theduration of hospitalization, the used antibiotics and antibiotic changesaccording to the culture results were recorded for all patients. The duration of hospitalization of patientswith and without culture growth was compared. In addition, the culture growinggroup was evaluated in itself according to the growing microorganism type interms of the duration of hospitalization.Results: While 39.1% (9patients) of the patients had culture growth, 60.9% (14 patients) had noculture (14 patients). Klebsiella pneumonia was detected in the culture of 4patients, pseudomonas aeruginosa in the culture of 4 patients and mycobacteriumtuberculosis in the culture of 1 patient. Although the duration ofhospitalization was longer in patients with (10.1 ± 5.1 days) than thosewithout culture growth (7.8 ± 5.5 days), there was no significant differencebetween two groups (p= 0.135). However, when patients with culture growth werecompared according to the microorganism type; it was detected that patientswith pseudomonas aeruginosa growth in the culture had significantly longerduration of hospitalization.Conclusion: Pseudomonasaeruginosa is one of the most common grow microorganisms in sputum cultures ofpatients with bronchiectasis. This factor increases the duration ofhospitalization of patients.
