PURPOSE: To determine the clinical utility of thoracic computed tomography (CT) in the medical intensive care unit (MICU).
METHODS: The records and thoracic CT scans of 155 consecutive patients admitted to our MICU between July 2011 and July 2012 were reviewed.
RESULTS: RESULTS: The mean age (SD) of the patients was 57.2 (14.0 ) years and 51.6% were male. The most common indications for obtaining a Thoracic CT were suspicion of pulmonary embolism (34.8%), respiratory failure of unspecified cause (12.9%), evaluation of pneumonia (12.2%) and suspicion of malignancy (12.2%). Thoracic CT scanning confirmed the initial diagnosis in 40.9 % of the cases, excluded the initial diagnosis in 59.1%, and provided an alternative or additional diagnosis in 88.0%. The most common final diagnoses were pneumonia (40.0%), pleural effusions (23.2%) and pulmonary embolism (4.5%). Thoracic CT scanning led to a change in management in 106 (68%) of the patients. Sixty three patients underwent procedures as a result of documented findings on the CT. The most common procedures performed were bronchoscopy (33), endotracheal tube repositioning (12) and thoracentesis/chest tube placement (11). Two (2.1%) out of the 96 patients who underwent thoracic CT with intravenous contrast developed contrast induced nephropathy.
CONCLUSIONS: Thoracic CT when performed in the MICU patient provides important information that often leads to a change in management.
CLINICAL IMPLICATIONS: Thoracic CT scanning often leads to a change in management in the MICU patient.
