REDUCE - Indication catalogue based ordering of chest radiographs in intensive care units

To advance a transition towards an indication-based chest radiograph (CXR) ordering in intensive care units (ICUs) without compromising patient safety.Single-center prospective cohort study with a retrospective reference group including 857 ICU patients. The routine group (n = 415) received CXRs at the discretion of the ICU physician, the restrictive group (n = 442) if specified by an indication catalogue. Documented data include number of CXRs per day and CXR radiation dose as primary outcomes, re-intubation and re-admission rates, hours of mechanical ventilation and ICU length of stay.CXR numbers were reduced in the restrictive group (964 CXRs in 2479 days vs. 1281 CXRs in 2318 days) and median radiation attributed to CXR per patient was significantly lowered in the restrictive group (0.068 vs. 0.076 Gy x cmA substantial reduction of the number of CXRs on ICUs was feasible and safe using an indication catalogue thereby improving resource management.DRKS00015621, German Clinical Trials Register.
