Abstract

Objective : To establish the scoring system for predicting mortality in pulmonary melioidosis.

Methods : This is a retrospective cohort study in patients who diagnosed as pulmonary melioidosis. The sample were collected at Khon Kaen Hospital from January 1st, 2017 to December 31st, 2018, as a training set. We use the clinical characteristics of severe pneumonia of this set to create the scoring system. We tested the validity of our system for predicting mortality in patients from January 1st, 2019 to June 30th, 2019, as a validation set.

Results : The scoring system was created from the training set of 245 patients. We found 9 factors associating to severity. These factors are mental status, rate of disseminated form, respiratory rate, heart rate, systolic blood pressure, absolute lymphocyte count, blood urea nitrogen, arterial pH, and PaO2/FiO2 with the adjusted odds ratio of 17.16, 5.01, 1.09, 1.02, 0.99, 0.99, 0.99, 0.00 and 0.99, respectively. The scoring system was then used on the validation set of 42 patients. The result showed
that the system can predict mortality correctly in high risk group and in very high-risk group that have the mortality equal to 66.7% and 87.5%, respectively. The sensitivity, specificity, positive likelihood ratio, negative likelihood ratio and Youden index in high risk group are 21.1, 91.3, 2.421, 0.865, and 0.325, respectively, while in very high-risk group are 36.8, 95.7, 8.474, 0.66, and 0.325, respectively.

Conclusions : The scoring system can predict the mortality correctly. This may help physicians plan better treatment, and reduce mortality rate.
