Abstract:
To evaluate current policies and practices regarding preparative fasting before contrast-enhanced computed tomography (CECT) and the knowledge and attitudes of radiology head nurses. Methods Radiology head nurses in 499 Chinese hospitals participated in an online survey on preparative fasting for CECT, which mainly included current departmental policies and practices and their knowledge and attitudes. Results Response rate was 89.8% (448/499). All surveyed hospitals established preparative fasting protocols, mainly based on guidelines for iodinated contrast media (ICM) usage (68.8%). For the nongastrointestinal CECT scan, the most frequent fasting duration for solid food, semiliquid diet, liquid diet, and clear liquids was 4 to 6 hours (215/422 [50.9%]), less than 6 hours (332/396 [83.8%] ), less than 6 hours (275/320, 85.9%), and less than 6 hours (151/189 [79.9%]), respectively. Forty-six percent of the respondents confirmed that unnecessary excessive fasting existed in practice, and the related patient discomfort occurred in 60.3% of the hospitals, mainly manifested as hypoglycemia (86.7%). Expert consensus and guidelines for iodinated contrast media usage (75%) were the leading approach to gain knowledge about preparative fasting; 90.6% of the respondents believed that the clinical scenarios requiring preparative fasting were the upper abdominal examinations. A majority of respondents (72.1%) believed that the current preparative fasting policies needed improvement. Conclusion Preparative fasting policies varied among hospitals in terms of the fasting content and duration. Respondents' opinions differed on fasting requirements based on various CECT examination sites and patients. The latest guideline regarding no fasting before CECT has not been fully adopted. Further research is required to promote the transformation of guideline evidence.
