Optimal Approach to Source Control in Intensive Care Unit Patients.

Source control is a cornerstone of managing infections and sepsis in the intensive care unit, requiring rapid recognition of infection, targeted diagnostic evaluation, and timely procedural or surgical intervention. This article presents a systems-based approach to identifying infection sources in critically ill patients through clinical assessment, targeted imaging, laboratory testing, and multidisciplinary collaboration. It outlines indications for conservative versus operative management across multiple organ systems. Emphasis is placed on early detection, anatomically focused intervention, prompt drainage of closed-space infections, judicious antibiotic use, and the role of coordinated care among intensivists, surgeons and proceduralists, and infectious disease specialists to optimize outcomes.
