Missing a Large Vessel Occlusion Stroke in a Patient with a History of Seizures.

Save to Library

July 8, 2022

A 58-year-old man with a past medical history of seizures presented to the emergency department (ED) with acute onset of left gaze deviation, expressive aphasia, and right-sided hemiparesis. The patient was evaluated by the general neurology team in the ED, who suspected an acute ischemic stroke and requested an evaluation by the stroke neurology team but did not activate a stroke alert. The stroke team concluded that the patient had suffered a focal seizure prior to arrival and had postictal deficits.

Diagnostic challenges in primary care: identifying and avoiding cognitive bias.

Save to Library

Rosen PD, Klenzak S, Baptista S. J Fam Pract. 2022;71:124-132.

Cognitive biases can impede decision-making and lead to poor care. This article summarizes the common types of cognitive errors and biases and highlights how cognitive biases can contribute to diagnostic errors. The authors apply these common types of errors and biases in four case examples and discuss how to mitigate these biases during the diagnostic process.

Sausser L. Kaiser Health News. May 24, 2022.

Lack of education contributes to misunderstandings and unhelpful preconceptions. This article discusses biases affecting the care of patients who are overweight. It introduces an educational effort to raise awareness of potential diagnostic and treatment actions affected by clinician bias to decrease safety for this patient population.

Management of Cardiac Arrest in Unconventional Locations.

Save to Library

May 16, 2022

This WebM&M describes two cases involving patients who became unresponsive in unconventional locations – inside of a computed tomography (CT) scanner and at an outpatient transplant clinic – and strategies to ensure that all healthcare teams are prepared to deliver advanced cardiac life support (ACLS), such as the use of mock codes and standardized ACLS algorithms.

Presenting complaint: use of language that disempowers patients.

Save to Library

Cox C, Fritz Z. BMJ. 2022;377:e066720.

As more patients are gaining access to their electronic health records, including clinician notes, the language clinicians use can shape how patients feel about their health and healthcare provider. This commentary describes how some words and phrases routinely used in provider notes, such as “deny” or “non-compliant”, may inadvertently build distrust with the patient. The authors recommend medical students and providers reconsider their language to establish more trusting relationships with their patients.

Clinician distress and inappropriate antibiotic prescribing for acute respiratory tract infections: a retrospective cohort study.

Save to Library

Brady KJS, Barlam TF, Trockel MT, et al. Jt Comm J Qual Patient Saf. 2022;48:287-297.

Inappropriate prescribing of antibiotics to treat viral illnesses is an ongoing patient safety threat. This study examined the association between clinician depression, anxiety, and burnout and inappropriate prescribing of antibiotics for acute respiratory tract infections (RTIs) in outpatient care. Depression and anxiety, but not burnout, were associated with increased adjusted odds of inappropriate prescribing for RTIs.

The Color of Care.

Chicago, IL: Harpo Productions, Smithsonian Channel: May 2022.

The COVID-19 pandemic revealed the impact of racial disparities and inequities on patient safety for patients of color. This film shares stories of families whose care was unsafe. The cases discussed highlight how missed and dismissed COVID symptoms and inattention to patient and family concerns due to bias reduces patient safety.

Identifying patients whose symptoms are underrecognized during treatment with breast radiotherapy.

Save to Library

Jagsi R, Griffith KA, Vicini F, et al for the Michigan Radiation Oncology Quality Consortium. JAMA Oncol. Epub 2022 Apr 21.

Concordance of patient-reported symptoms and provider-documented symptoms is necessary for appropriate patient care and has clinical implications for research. This study compared patient-reported symptoms (pain, pruritus, edema, and fatigue) following radiotherapy for breast cancer with provider assessments. Underrecognition of at least one symptom occurred in more than 50% of patients. Underrecognition was more common in Black patients and those seen by male physicians. The authors suggest that interventions to improve communication between providers and patients may not only improve outcomes but also reduce racial disparities.

Patel SJ, Ipsaro A, Brady PW. Hosp Pediatr. 2022;Epub Feb 28.

Diagnostic uncertainty can arise in complex clinical scenarios. This qualitative study explored how physicians in pediatric emergency and inpatient settings mitigate diagnostic uncertainty. Participants discussed common mitigation strategies, such as employing a “diagnostic pause.” The authors also noted outstanding gaps regarding communicating diagnostic uncertainty to families.

Effects of tall man lettering on the visual behaviour of critical care nurses while identifying syringe drug labels: a randomised in situ simulation.

Save to Library

Lohmeyer Q, Schiess C, Wendel Garcia PD, et al. BMJ Qual Saf. 2022;Epub Mar 8.

Tall Man lettering (TML) is a recommended strategy to reduce look-alike or sound-alike medication errors. This simulation study used eye tracking to investigate how of ‘tall man lettering’ impacts medication administration tasks. The researchers found that TML of prelabeled syringes led to a significant decrease in misidentified syringes and improved visual attention.

Tee QX, Nambiar M, Stuckey S. J Med Imaging Radiat Oncol. 2022;66:202-207.

Diagnostic errors in radiology can result in treatment delays and contribute to patient harm. This article provides an overview of the common cognitive biases encountered in diagnostic radiology that can contribute to diagnostic error, and strategies to avoid these biases, such as the use of a cognitive bias mitigation strategy checklist, peer feedback, promoting a just culture, and technology approaches including artificial intelligence (AI).

Choosing wisely in clinical practice: embracing critical thinking, striving for safer care.

Save to Library

Furlan L, Francesco PD, Costantino G, et al. J Intern Med. 2022;291:397-407.

Overtreatment and overuse can have unanticipated consequences, ranging from patient anxiety while awaiting test results to medical complications. The authors identify several factors that can contribute to patient overtreatment (fear of uncertainty, cognitive bias, applying low-quality evidence, and overfocusing on diagnosis). Interventions to overcome these issues include educating clinicians that uncertainty is a part of medicine and shifting to a focus on patient-centered management rather than focusing on identifying a diagnosis.
