Antimicrobial resistance has become increasingly dire as the rapid emergence of drug resistance, especially gram-negative pathogens, has outpaced the development of new antibiotics. At a recent virtual symposium, Dr Hsu Li Yang, Vice Dean (Global Health) and Programme Leader (Infectious Diseases), NUS Saw Swee Hock School of Public Health, presented epidemiological data on multidrug-resistant (MDR) gram-negative bacteria (GNB) in Asia, while Dr Tan Thuan Tong, Head and Senior Consultant, Department of Infectious Diseases, Singapore General Hospital (SGH), focused on the role of ceftazidime-avibactam in MDR GNB infections. Dr Andrea Kwa, Assistant Director of Research, Department of Pharmacy, SGH, joined the panel in an interactive fireside chat, to discuss challenges, practical considerations, and solutions in MDR gram-negative infections. This Pfizer-sponsored symposium was chaired by Dr Ng Shin Yi, Head and Senior Consultant of Surgical Intensive Care, SGH.

SELECT model predicts survival in Asian patients with malignant pleural effusion

02 Dec 2020

A study has found that the LENT, modified-LENT, and PROMISE scores have poor accuracy of survival prognostication in Asian patients with malignant pleural effusion (MPE) undergoing pleuroscopy.

The new SELECT (sex, Eastern Cooperative Oncology Group status, leukocyte count, EGFR mutation, chemotherapy, and primary tumour type) prognostication model, however, accurately identifies patients with a high chance of survival at 90 days.

The authors retrospectively reviewed the medical records of patients with MPE obtained from an Asian pleuroscopy database from 2011 to 2018 to evaluate the performance of LENT, modified‐LENT, and clinical PROMISE scores; identify predictors of survival; and develop an alternative prognostication tool should current scores lack accuracy.

They evaluated the prognostic capability of current available scores using C-statistics and assessed demographic and clinical variables as predictors. An alternative model was also developed using logistic regression.

The C-statistics for modified-LENT (0.59, 95 percent confidence interval [CI], 0.52–0.67) did not significantly differ from LENT (0.56, 95 percent CI, 0.49–0.63) in 130 patients. The C-statistic for PROMISE was 0.72 (95 percent CI, 0.53–0.91) in 57 patients.

In the alternative prognostication model (n=147), SELECT accurately predicted 90-day mortality (C-statistic, 0.87, 95 percent CI, 0.79–0.95). Using a predicted probability of 90-day mortality cutoff point of 10 percent, SELECT sensitivity, specificity, positive and negative predictive values, and positive and negative likelihood ratios were 0.91, 0.68, 0.34, 0.98, 2.83, and 0.13, respectively.

“LENT and PROMISE scores prognosticate survival in patients with MPE. Prognostication guides the selection of interventions and management,” the authors said.
