“…Chest radiographs (CXRs) are obtained frequently for intensive care unit (ICU) patients, on a routine basis, after a change in clinical situation or after surgery and other certain procedures. Multiple investigators have studied the clinical value of routine CXRs following central venous catheterization, endotracheal intubation and chest tube placement or removal [ 1 ]-[ 12 ]. Others have studied the value of daily routine CXRs in a mixed ICU population or in mechanically ventilated patients only [ 13 ]-[ 22 ] The diagnostic and therapeutic efficacy of these routine CXRs is known to be low [ 1 ]-[ 3 ],[ 6 ]-[ 9 ],[ 11 ],[ 13 ],[ 14 ],[ 16 ]-[ 19 ],[ 22 ].…”
