![]() ![]() aeruginosa infection with a high degree of accuracy, equal to or comparable to the existing P. The 60-B-r-I-NG was developed for predicting P. NG tube feeding before admission, bronchiectasis, immunocompromisation, atelectasis, pulmonary fibrosis and lung bleb were risk factors for pseudomonal CAP in the elderly. People who scored at least two should receive empirically antipseudomonal medication. The “60-B-r-I-NG” risk score was named after the 4 abbreviated risk variables and found to have good predicative capability (AuROC = 0.77) and accuracy comparable to or near true P. Nasogastric (NG) tube feeding (odd ratios OR = 40.68), bronchiectasis (B) (OR = 4.13), immunocompromised condition (I) (OR = 3.76), and other chronic respiratory illnesses (r) such as atelectasis, pulmonary fibrosis, and lung bleb (OR = 2.61) were the specific risk factors for infection with P. ![]() The inclusion criteria were met by 81 and 104 elderly patients diagnosed with CAP caused by P. aeruginosa infection were analysed using logistic regression, and the instrument was developed by scoring each risk factor based on the beta coefficient and evaluating discrimination and calibration using the area under the receiver operating characteristic curve (AuROC) and observed versus predicted probability (E/O) ratio. ![]() aeruginosa-causing CAP, admitted between January 1, 2016, and June 30, 2021. MethodsĪ retrospective data collection from an electronic database involved the elderly hospitalized patients with P. The purpose of this study was to identify risk factors and develop a risk predictor for Pseudomonas aeruginosa infection in older adults with community-acquired pneumonia (CAP). Antipseudomonal agents should be selected as an empirical treatment for elderly patients at high risk for developing this infection. In Thailand, the incidence of community-acquired pseudomonal pneumonia among 60- to 65-year-olds ranges from 10.90% to 15.51%, with a mortality rate of up to 19.00%. ![]()
