Psychological safety is an important principle in identifying problems and improving patient outcomes. This narrative review highlights five best practices to foster psychological safety in radiology residencies – (1) establish clear goals and educational strategies, (2) build a formal mentoring program, (3) assess psychological safety, (4) advocate for radiologists as educators, and (5) support non-radiology staff. Although the review focuses on radiology residency programs, these strategies can be adapted to any residency program.

Clinician skills can decrease with age. This retrospective analysis of 1.9 million preliminary interpretations of radiology imaging findings examined the relationship between radiologist age and diagnostic errors. While the overall mean error rate for all radiologists was low (0.5%), increasing age was associated with increased relative risk of diagnostic errors.
Chekmeyan M, Baccei SJ, Garwood ER. J Am Coll Radiol. 2023;Epub Jul 7.
Artificial intelligence (AI) has become a useful tool to support radiologists in diagnostic imaging. In this study, discordant findings between the radiologist and AI (negative by radiologist report, positive by AI report, with unviewed AI decision support system output) triggered an automatic manual review of the diagnostic images. More than 111,000 CT studies were analyzed, with 46 triggering the automatic review; of those, 26 (0.02%) were true positives (i.e., missed diagnosis by radiologist but identified by AI).

Like many clinical areas, a variety of system factors can influence diagnostic error rates in neuroradiology. This study included 564 neuroradiologic examinations with diagnostic error and 1,019 without error. Diagnostic errors were associated with longer interpretation times, higher shift volume, and weekend interpretation.

Numerous factors can hinder safe radiology practices, such as communication failures and image interpretation errors. Based on semi-structured interviews with 17 radiologists in Sweden, this study identified 20 themes at the individual-, organization-, technology-, task-and environment-levels describing factors supporting patient safety in radiology. Factors described by participants included the use of standardized tools and work routines (e.g., checklists), handoffs, and incident reporting systems.

Fostering a culture of safety is a core patient safety objective. This survey of 425 radiologic technologists explored differences in radiation safety culture between staff technologists and those in leadership roles. Findings identified several positional hierarchical imbalances in perceived determinants of safety culture, which could hinder efforts to establish a just culture and a positive organizational radiation safety culture.
Murphy DR, Zimolzak AJ, Upadhyay DK, et al. J Am Med Inform Assoc. 2023;30:1526-1531.
Measuring diagnostic performance is essential to identifying opportunities for improvement. In this study, researchers developed and evaluated two electronic clinical quality measures (eCQMs) to assess the quality of colorectal and lung cancer diagnosis. Each measure used data from the electronic health record (EHR) to identify abnormal test results, evidence of appropriate follow-up, and exclusions that signified unnecessary follow-up. The authors describe the measure testing results and outline the challenges in working with unstructured EHR data.
Gefter WB, Hatabu H. Chest. 2023;163:634-649.
Cognitive bias, fatigue, and shift work can increase diagnostic errors in radiology. This commentary recommends strategies to reduce these errors in diagnostic chest radiography, including checklists and improved technology (e.g., software, artificial intelligence). In addition, the authors offer practical step-by-step recommendations and a sample checklist to assist radiologists in avoiding diagnostic errors.
Petts A, Neep M, Thakkalpalli M. Emerg Med Australas. 2023;35:466-473.
Misinterpretation of radiology test results can contribute to diagnostic errors and patient harm. Using a set of 838 pediatric and adult radiographic examinations, this retrospective study found that radiographers’ interpretations can complement emergency clinicians’ interpretations and increase accuracy compared to emergency clinician interpretation alone.

Appropriate follow-up of incidental abnormal radiological findings is an ongoing patient safety challenge. Inadequate follow-up can contribute to missed or delayed diagnosis, potentially resulting in poorer patient outcomes. This study describes implementation of an electronic health record-based referral system for patients with incidental radiologic finding in the emergency room.

Computed tomography (CT) scans are important diagnostic tools but can present serious dangers from overexposure to radiation. Researchers reviewed 133 radiation incidents reported to one NHS trust from 2015-2018. Reported events included radiation incidents, near-miss incidents, and repeat scans. Most events were investigated using a systems approach, and staff were encouraged to report all types of incidents, including near misses, to foster a culture of safety and enable learning.

Radiological interpretation errors can result in unnecessary additional tests, wrong treatment and delayed diagnosis. This study explored the correlation between neuroradiologists’ diagnostic errors and attendance at institutional tumor boards. Results show that higher attendance at tumor boards was strongly correlated with lower diagnostic error rates. The researchers recommend increased and continuous attendance at tumor boards for all neuroradiologists.

Incomplete or delayed communication of imaging results can result in harm to the patient and have legal ramifications for the providers involved. This commentary presents a closed-loop communication model for the ordering clinician and radiologist. The model suggests the ordering clinician categorize the radiology report as “concordant” or “discordant”, and if discordant, provide an explanation.

While pediatric musculoskeletal radiograph misinterpretations are rare, it is important to know what features of the image area are associated with false-positive or false-negative diagnoses. In this study, pediatric emergency medicine physicians were asked to interpret radiographs with and without known fractures. False-positive diagnosis (i.e., a fracture was identified when there was none) were reviewed by an expert panel to identify the location and anatomy most prone to misdiagnosis.
WebM&M Case July 8, 2022

This WebM&M highlights two cases of patient safety events that occurred due to medication dosing related to diagnostic imaging. The commentary highlights the challenges of administering sedation for diagnostic imaging, the use of risk stratification to understand patient risk for oversedation, and strategies for appropriate monitoring and communication.

To reduce medical errors caused by fatigue, the Accreditation Council for Graduate Medical Education (ACGME) adopted duty hour restrictions for ACGME-accredited residency programs; however, other healthcare fields have not yet done so. This review presents the limited existing evidence for regulating duty hours for radiologists and proposes that additional research needs to be completed before implementing restrictions.

Failure to follow up on abnormal diagnostic test results can cause delays in patients receiving appropriate care. This hospital used an artificial intelligence natural language processing system to identify radiology reports requiring follow-up. The system triggered automated notifications to the patient and ordering provider, and tracked follow-ups to completion. System development, deployment and next steps are detailed.

Root cause analysis is a commonly used tool to identify systems-related factors that contributed to an adverse event. This study assessed a system-based approach, (i.e., collaborative case reviews (CCR) co-led by radiology and an institutional patient safety program) to identify contributing factors and explore the strength of recommended actions in the radiology department at a large academic medical center. Stronger action items, such as standardization of processes, were implemented in 41% of events, and radiology had higher completion rates than other hospital departments.
