Rationale and Objectives
This study aimed to assess the effectiveness of practical preventive strategies (i.e.,
venous vulnerability assessment and prevention scan protocol rules) taken by our radiology
team (radiology nurses, radiology technicians, radiologists) on reducing extravasation
of contrast media (ECM) during CT.
Materials and Methods
A total of 73,931 patients who underwent contrast-enhanced CT scans between January
2013 and December 2019 were retrospectively included. Venous vulnerability assessment
by the radiology team began in 2015, and prevention scan protocol rules for the prevention
of ECM were added in 2017. We defined each period as follows: 2013–2014, no prevention
(Period A); 2015–2016, early prevention (Period B, venous vulnerability assessment
only); and 2017–2019: late prevention (Period C, venous vulnerability assessment with
prevention scan protocol rules). The incident reports, radiology reports, and medical
records of patients in whom ECM occurred were reviewed. We compared the frequency
of ECM during each period.
Results
ECM occurred in 0.39% (292/73,931) of the patients. The frequencies of ECM for Periods
A, B, and C were 0.62% (121/19,505), 0.43% (89/20,847), and 0.24% (82/33,579), respectively.
There were significant differences in the frequencies of ECM among the three periods
(Chi-squared test, p < 0.01).
Conclusion
Implementation of venous vulnerability assessment and prevention scan protocol rules
by a radiology team can be a practical and simple solution to reduce the risk of ECM
during CT.
