Rates and reasons for safety incident reporting in the medical imaging department of a large academic health sciences centre

Abstract

Background: Safety incident reporting is essential in medical imaging (MI) departments due to the fast-paced environment and high patient volume. However, there is an evident knowledge gap in the identification and investigation of contributing factors to incidents reports in MI departments. The objective of this study was to investigate the following rates of incident reporting in a MI department at a large academic health sciences centre: departmental incident rate, incident rates per imaging modality, and incident rates per incident type. Characteristics associated with the most frequently occurring incident types were examined to identify opportunities for quality improvement.

Methods: This observational, retrospective study collected approximately 665 MI incident reports submitted by staff between July 2018 and July 2019. Individual incident reports were categorized according to imaging modality and incident type. Subcategories of the top four incident types were also created to identify possible contributory factors based on the staff member's safety incident report submission.

Results: The safety incident rate for the entire medical imaging department was 0.263%. The safety incident reporting rate was calculated (# of incidents reported per modality total/ # of completed exams in that modality x 100%) for each modality and varied from 0.113 to 1.26%. The four highest safety incident rates were from adverse drug reaction (ADR) (21.5%), followed by delay in care/treatment (18.9%), identification/documentation/order (18.5%) and extravasation (11.4%). Possible contributory factors involved transfer of accountability (TOA)/communication barriers, and incorrect ordering information. Further analysis was also completed to assess whether patients that experienced an ADR or extravasation incident followed the correct protocols.

Discussion: This study demonstrated the importance of how analysis of incident report data can be used to uncover opportunities for quality improvement in the medical imaging department. However, more information must be collected at the time of safety incident report submission to allow for quality improvement. Investigators hope that by future standardization of safety incident reporting, with the increased use of drop-down menus to capture more open-ended responses, corrective strategies can be implemented to address safety concerns in MI departments. In comparison to incident reporting rates published in similar studies, there may be a significant underrepresentation of safety incident reports filed from underreporting. Reducing barriers to reporting is essential in improving the effectiveness of the current safety incident reporting system.
