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.

Patients with dark skin tones are not well represented in health education, particularly dermatology, which can result in delayed diagnosis. In this scoping review, thirteen articles were identified assessing the confidence of students and healthcare providers in assessing patients with dark skin tones.  Overall, confidence was low but tailored training somewhat improved confidence. The author asserts more research and education is needed outside dermatology, for example, when assessments use terms such as pale, redness, or blue.

Miscommunication between pathologists and surgeons can lead to significant patient harm. This study identified multiple discrepancies between pathologist-listed diagnoses included in intraoperative consult notes compared to surgeon-dictated operative notes. Discrepancies were most common in multipart cases and those involving deferrals.

Clinical care pathways (CP) standardize care to ensure evidence-based practices are consistently followed. This study analyzed missed diagnostic opportunities (MDO) of pediatric musculoskeletal infections that could have been mitigated had the CP recommendations been adhered to. Misinterpretation of laboratory results was a critical contributor to MDO by both pediatric emergency providers and orthopedic consultants.

Telemedicine can improve access to specialist care and reduce time to treatment. This systematic review including 44 articles examined the diagnostic agreement between teledermatology and face-to-face consults. The overall average diagnostic agreement was 68.9%, but subgroup analyses identified significantly higher agreement when dermatologists conducted face-to-face and teledermatology consults, rather than non-specialists (i.e., primary care or emergency medicine physicians).

Delayed cancer diagnosis is a major contributor to suboptimal outcomes and malpractice claims. In this review, factors contributing to delayed diagnosis of blood cancers are explored. Initial delays resulted from patients’ non-specific symptoms such as fatigue and symptoms that came and went. After seeking care, factors contributing to delayed diagnosis include seeing a locum general practitioner, being Black or a woman, and having multiple chronic conditions.

Radiologic diagnostic errors can result in delayed or unnecessary treatment. This paper describes five types of cognitive biases, with accompanying case study and images, that result in misdiagnosis. Both individual education and system-level solutions are described.

Changes in healthcare delivery due to the COVID-19 pandemic resulted in delays in care that can lead to patient harm. In this study using patient safety event data submitted to the VHA National Center of Patient Safety, researchers identified healthcare delays involving laboratory results, treatment and interventional procedures, and diagnosis.   

Previous research has identified racial and ethnic discrepancies in pulse oximetry measurement which can lead to delays in diagnosis or treatment. This editorial discusses racial and ethnic biases in clinical algorithms and devices and two emerging approaches – photoacoustic imaging and polarized light oximetry – that have potential to address the racial and ethnic biases in pulse oximetry.

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.

The effective use of resources through stewardship initiatives can support error reduction through focusing actions of care. This commentary discusses how diagnostic stewardship can enhance diagnostic testing behaviors across the diagnostic process.

Missed diagnosis of infectious diseases can have serious consequences for patient safety. This article describes a delayed diagnosis of disseminated tuberculosis in a patient with lung cancer and discusses the how cognitive biases and systems failures contributed to the diagnostic error.

Metacognition (e.g., when one reflects on one’s own decision and decision making) is an approach to reducing diagnostic errors. Using data from the Melanoma Pathology Study (M-PATH) and Breast Pathology Study (B-PATH), researchers assed pathologists’ metacognition by examining their diagnostic accuracy and self-confidence. Results showed pathologists with increased metacognition sensitivity were more likely to request a second opinion for incorrect diagnosis than they were for a correct diagnosis.

Studies have shown diagnostic discordance in evaluation of surgical pathology specimens. In this study, pathologists and pathology residents were asked to diagnose surgical pathology or cytopathology cases and provide a diagnosis. Most respondents provided the correct diagnosis for most of the cases; 35% of cases were wholly or partially misdiagnosed. Educational and process changes (e.g., requiring subspecialist over-read for some diagnoses) were implemented in the pathology department in response, resulting in substantial improvement in error rates.

Wrong blood in tube (WBIT) errors can result in serious diagnostic and treatment errors, but may go unrecognized by clinical staff. In this study, machine learning was used to identify potential WBIT errors which were then compared to manual review by laboratory staff. The machine learning models showed higher accuracy, sensitivity, and specificity compared to manual review. 

Black and brown patients have experienced disproportionately poorer outcomes from COVID-19 infection as compared with white patients. This study found that patients who identified as Asian, Black, or Hispanic may not have received timely diagnosis or treatment due to inaccurately measured pulse oximetry (SpO2). These inaccuracies and discrepancies should be considered in COVID outcome research as well as other respiratory illnesses that rely on SpO2 measurement for treatment.
