Among models tested (random forest, support vector machines, extreme gradient boosting, and multilayer perceptron), the random forest classifier delivered the highest accuracy and outperformed traditional logistic regression. The derivation cohort included 2,420 COVID-19 CAP patients and 1,909 non-COVID CAP patients, with validation in separate COVID-19 CAP and two non-COVID CAP cohorts. Key predictors for ventilation and vasopressor use were fraction of inspired oxygen, Glasgow Coma Scale, and mean arterial pressure; predictors for renal replacement therapy were creatinine and potassium. The study reports AUCs ranging from 0.74 to 0.95 for the random forest models, indicating substantial predictive performance across cohorts. Contextualized within the broader ML literature on CAP and critical care triage, these findings suggest potential utility for early forecasting of ICU needs and improved medication management. Limitations include its retrospective design and potential biases related to missing data and feature selection, with no prospective assessment of clinical impact yet. Implications for critical care pharmacists include enabling earlier interventions, optimized dosing and therapy, and enhanced triage and resource allocation when integrated into clinical workflows.\",\n \"study\": {\n \"title\": \"Machine Learning Accurately Predicts Need for Critical Care Support in Patients Admitted to Hospital for Community Acquired Pneumonia\",\n \"journal\": \"Critical Care Explorations\",\n \"design\": \"Retrospective...","thumbnail_url":"https://img.transistorcdn.com/W5ppyJiVvpeq5HNrnsz_zaMmU5rmab3dOuTiTdwfeYQ/rs:fill:0:0:1/w:400/h:400/q:60/mb:500000/aHR0cHM6Ly9pbWct/dXBsb2FkLXByb2R1/Y3Rpb24udHJhbnNp/c3Rvci5mbS9hMTdi/ZTcyYTUyYTdmMmY2/Y2VmYzc4ZmIwYzA4/NTdlMC5wbmc.webp","thumbnail_width":300,"thumbnail_height":300}
