How often should daily chest X-rays (CXRs) be conducted in critically ill patients?

Daily chest X-rays (CXRs) in critically ill patients should not be routinely conducted due to the potential for unnecessary radiation exposure and the impact on patient care without significant benefits. Guidelines and evidence suggest that daily CXRs may not significantly alter management in many cases. Instead, CXRs should be performed based on clinical indications rather than on a strict daily schedule.

In practice, CXRs can be beneficial for monitoring specific conditions, such as checking for complications related to ventilation, confirming the placement of lines or tubes, or evaluating changes in a patient’s respiratory status. However, the routine performance of these imaging studies without clinical reasons tends to lead to over-utilization, increasing healthcare costs and potentially hindering patient care due to false findings or the misinterpretation of static conditions that do not require daily review.

Patients in critical care settings often undergo multiple assessments and monitoring; therefore, the decision to perform a CXR daily should be clinically driven, based on the individual patient’s needs and evolving conditions. This tailored approach prioritizes patient safety and optimal resource utilization in the critical care environment.
