Anchoring bias is relying on initial diagnostic impression despite subsequent information to the contrary. In this study, radiologists were asked to read a mammogram and were told a random number which researchers claimed was the probability the mammogram was positive for breast cancer. Radiologists' estimation of breast cancer reflected the random number they were given prior to viewing the image; however, when they were not given a prior estimation, radiologists were highly accurate in diagnosing breast cancer.

Prior research found that cancer, infections, and vascular events (the “big three”) account for nearly half of all serious misdiagnosis-related harm identified in malpractice claims. This retrospective analysis of malpractice claims data from 2008 to 2017 found that oncology-related errors represented the largest source of radiology malpractice cases with diagnostic allegations. Imaging misinterpretation was the primary contributing factor.

Late diagnosis of upper extremity fractures can lead to delays in treatment. When two radiologists reviewed whole-body CT scans, each missed known fractures and identified previously unknown fractures. Slice thickness was not significantly associated with missed fractures; however, missed and late diagnosis occurred more often between the hours of 5pm and 1am.

A 31-year-old woman presented to the ED with worsening shortness of breath and was unexpectedly found to have a moderate-sized left pneumothorax, which was treated via a thoracostomy tube. After additional work-up and computed tomography (CT) imaging, she was told that she had some blebs and mild emphysema, but was discharged without any specific follow-up instructions except to see her primary care physician.

Delayed diagnosis and treatment of breast cancer can lead to poor outcomes. Based on multi-year data from one health system, the authors of this cohort study found that black women with screen-detected breast cancers were more likely than white women to experience diagnostic delays, including delays in diagnostic evaluation and biopsy. The delay in diagnosis was also associated with an increase in breast cancer mortality.

Incorrect interpretation of radiologic images can result in delayed diagnosis or unneeded additional tests and treatment. This commentary describes the visual illusions radiologists use in detecting and categorizing abnormalities, and recommends further research into the ways visual illusions are used in order to improve diagnostic safety.

Overdiagnosis of breast cancer and the resulting overtreatment can cause physical, emotional, and financial harm to patients. Analysis of observational data and modelling indicates overdiagnosis accounts for less than 10% of invasive breast cancer in patients aged 50-69. Understanding rates of overdiagnosis can assist in ascertaining the net benefit of breast cancer screening.

Lack of appropriate follow up of diagnostic imaging can result in care delays, patient harm, and death. This report summarizes an investigation of 25 imaging failures in the British National Health Service (NHS). The analysis identified communication and coordination issues resulting in lack of action and reporting of unanticipated findings to properly advance care. Recommendations to improve imaging in the NHS include use of previous analyses to enhance learning from failure.

This article describes the Yorkshire contributory factors framework, which identifies factors contributing to safety errors across four hierarchical levels (active errors, situational factors, local working conditions, and latent factors) and two cross-cutting factors (communication systems and safety culture). The authors apply this framework to a case of missed mass on breast imaging and discuss how its use can help health systems effectively learn from error and develop systematic, proactive programs to improve safety and manage safety issues.

Artificial intelligence (AI) systems can support diagnostic decision-making. This study evaluates diagnostic “shortcuts” learned by AI systems in detecting COVID-19 in chest radiographs. Results reveal a need for better training data, improved choice in the prediction task, and external validation of the AI system prior to dissemination and implementations in different hospitals.

Misdiagnosis of child abuse has far-reaching implications. This commentary discusses the ethical tensions faced by pediatric radiologists of both over- and under-diagnosing child abuse. The author suggests ways that physicians and professional societies can partner with legal advocates to create a more balanced pool of experts to alleviate perceptions of bias and acknowledge harms of misdiagnosed child abuse.

Diagnostic radiology mistakes contribute to delays and ineffective treatments that contribute to patient harm. This webinar examined factors that contribute to errors in image interpretation and will highlight strategies to learn from those errors to improve diagnostic process reliability. Registering for the program provides access to the recording.

After a breast mass was identified by a physician assistant during a routine visit, a 60-year-old woman received a diagnostic mammogram and ultrasound. The radiology assessment was challenging due to dense breast tissue and ultimately interpreted as “probably benign” findings. When the patient returned for follow-up 5 months later, the mass had increased in size and she was referred for a biopsy.

Extended work shifts for nurses and physicians have been linked to increased risk of errors. In this systematic review, the authors discuss the impact of shift work disorder on errors and safety implications for radiographers. Studies suggested a positive correlation between errors and increased mental and physical fatigue resulting from shift work or rapid shift rotation, however none of the identified studies focused specifically on radiology professionals.

The harm of misdiagnosis can be extended by lack of clinician recognition and acceptance of the error when a patient raises concerns. This news story shares the experience of a physician-patient whose recognition of a diagnostic mistake was initially dismissed. The author defines the repeated lack of organizational willingness to resolve the situation as a normalized deviance in health care.

The authors analyzed CT interpretation errors committed by radiology fellows working off-hours over a four-year period and found that interpretation errors occurred more frequently at night and in the latter half of night assignments.

This study reviewed safety events involving diagnostic or interventional radiology at one children’s hospital and used data from the root cause analyses to characterize the contributing system failures and key activities and processes. Approximately one-quarter of the safety events were secondary to diagnostic errors.  The most common key processes involved in these events were diagnostic and procedural services, and the most common key activities were interpreting/analyzing and coordinating activities.

This systematic review investigated the use of anatomical side markers (ASM), which are used in radiology to identify the correct anatomical side and prevent confusion. The seven studies included demonstrated that use of ASMs is common, but the literature documented some barriers to use, such as risk of obscuring essential anatomical parts.
