Multi-detector computed tomography in critically ill patients.
BACKGROUND
There is a lack of studies showing the overall impact of multi-detector computed tomography (MDCT) on the treatment of critically ill patients in a general intensive care unit (ICU) setting.


METHODS
A prospective observational study on the effects of MDCT on the treatment of patients in a 12-bed medical-surgical ICU in a university hospital providing tertiary care.


RESULTS
During the 9-month study period, there were 343 admissions with ICU length of stay longer than 48 h. Of these patients, 64 (19%) had had inconclusive findings with other modalities of radiological imaging, and they underwent altogether 82 MDCT examinations. Fifty examinations (61%) resulted in a change of treatment. The changes included 22 surgical interventions, 16 percutaneous or paranasal interventions, 15 changes of antimicrobial therapy, three withdrawals of active treatment, and four other changes of treatment. Eight patients underwent two and one patient underwent three changes of treatment. Twenty examinations (24%) were regarded as otherwise necessary for clinical decision-making, although no change in the treatment was indicated. Twelve examinations (15%) failed to provide any additional information relevant to the patient's treatment.


CONCLUSIONS
Sixty-one percent of the MDCT examinations led to a change of treatment, and 24% of them otherwise contributed to or supported clinical decision-making, suggesting that MDCT examination is helpful in the case of general ICU patients, with inconclusive findings with other imaging modalities.
