Adherence to guidelines aimed at preventing post-contrast acute kidney injury (PC-AKI) in radiology practices: a survey study

Background: New insights into post-contrast acute kidney injury (PC-AKI) have recently led to the guidelines on the prevention of PC-AKI being updated. However, little is known about the barriers and facilitators involved in guideline adherence by radiology practices. Purpose: To evaluate barriers and facilitators to the adherence of PC-AKI guidelines. Material and Methods: Radiologists visiting the European Society of Urogenital Radiology (ESUR) 2018 meeting, as well as ESUR members were contacted to fill in an electronic questionnaire on the implementation of PC-AKI guidelines applying to their local radiology practices. Results: Of the 145 responding radiologists representing radiology practices, 127 (88%) confirmed having a PC-AKI protocol in place in their radiology practice, of which 61 (48%) used a protocol as specified in a (inter)national guideline. The majority of radiology practices of the respondents used the ESUR guideline (40%). Barriers for not using PC-AKI prevention guidelines were related to a lack of outcome expectancy. Barriers for not using the protocol as specified were related to a lack of agreement with specific recommendations, lack of motivation, guideline-specific factors, and environmental factors. Self-reported facilitators consisted of guideline-specific factors. Conclusion: Guidelines for the prevention of PC-AKI seem to be widely implemented among radiology practices, and regularly locally modified because of barriers involved in agreement and behavior. Knowledge of the barriers and facilitators of guideline adherence will aid future efforts aimed at bridging the gap between awareness and implementation of evidence-based guidelines in radiology practices.
