Delayed diagnosis and treatment of stroke leads to adverse patient outcomes. This cross-sectional study identified gender disparities in the treatment of patients with large vessel occlusion (LVO) acute ischemic stroke (AIS), with women being less likely to be routed directly to comprehensive stroke centers compared with men, despite having more significant stroke syndromes.

Previous research has found that three diseases (vascular events, infections, and cancers) account for approximately 50% of all serious misdiagnosis-related harm. Based on a sample of 21.5 million US hospital discharges, the authors estimated that 795,000 adults in the US experience serious misdiagnosis-related harm (permanent morbidity or mortality) attributable to these three disease categories each year.

Recognizing and learning from mistakes is a core component of medical and nursing education. Based on video recordings of bedside teaching lessons, this study explored how instructors react to and address student mistakes during bedside teaching lessons. Findings highlight the importance of giving purposeful feedback and allowing students the opportunity to recognize and correct their mistakes.

Patients presenting to the emergency department (ED) with a chief complaint of dizziness require prompt assessment to rule in or out a serious diagnosis such as stroke. A retrospective chart review was performed on more than 1,500 adult patients presenting to the ED with dizziness to estimate vestibular syndrome classifications (i.e., acute, episodic, chronic) and rates of misdiagnosis. Approximately 20% of patients were diagnosed with acute vestibular syndrome (e.g., stroke) and 10% had an unclear vestibular syndrome at time of ED discharge. Of those with follow-up exams, nearly one-third received a different diagnosis, but only 3.2% received a different vestibular classification.

Vulnerable populations, such as those with limited English proficiency, minoritized race or ethnicity, migrant populations, or patients qualifying for public insurance, may be at higher risk for adverse health events. In this review, researchers sought to identify frequency and causes of diagnostic error of vulnerable populations presenting to the emergency department with cardiovascular or cerebrovascular/neurological symptoms. Black patients presenting with cardiovascular symptoms had significantly higher odds of diagnostic error. Other demographic factors did not show similar associations, nor did studies of patients with cerebrovascular/neurological symptoms.

Heuristics, uncertainty, and bias are contributors to diagnostic error, overuse, and treatment delay. This story describes the care experience of an adolescent patient whose rare immune system condition was initially diagnosed as being psychological in origin, which contributed to persistent misdiagnosis.

A missed or delayed diagnosis of stroke places patients at risk of permanent disability or death. This article describes how interdisciplinary teams used a failure modes, effects, and criticality analysis (FMECA) to create an acute stroke diagnostic process map, identify failures, and highlight existing safeguards. The FMECA process identified several steps in the diagnostic process as the most critical failures to address, including failure to screen patients for stroke soon after presentation to the Emergency Department (ED), failure to obtain an accurate history, and failure to consider a stroke diagnosis during triage.

Fall prevention is a safety priority in hospital settings. This study found that Smart Socks – socks containing pressure sensors that detect when a patient is trying to stand up – reduced fall rates among patients at risk of falls in one hospital’s neurological and neurosurgical department. Over a 13-month period, investigators observed a decreased fall rate (0 per 1000 patient days) among patients wearing Smart Socks compared to prior to intervention implementation (4 per 1000 patient days).

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.

Misdiagnosis of neurological conditions, such as stroke, can lead to delays in treatment and patient morbidity and mortality. This report outlines findings from an inquiry into one misdiagnosis attributed to one neurologist in Ireland and discusses the leadership, system, process, and communication failures which permitted misdiagnoses to go unchecked.

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.

Missed diagnosis of stroke in emergency medicine settings is an important patient safety problem. In this study, researchers interviewed emergency medicine physicians about their perspectives on diagnostic neurology and use of clinical decision support (CDS) tools. Themes emerged related to challenges in diagnosis, neurological complaints, and challenges in diagnostic decision-making in emergency medicine, more generally. Participating physicians were enthusiastic about the possibility of involving CDS tools to improve diagnosis for non-specific neurological complaints.

Diagnostic error and misdiagnosis of stroke patients can lead to preventable adverse events, such as treatment delays and adverse outcomes. Researchers at a Swiss hospital retrospective reviewed patients admitted for transient ischemic attack (TIA) or ischemic stroke and found that a trigger tool could accurately identify preventable events among patients with adverse events and no-harm incidents. The most common preventable events were medication events, pressure injuries, and healthcare-associated infections.

Prior research has found that racial/ethnic minorities may be at higher risk for adverse patient safety outcomes. This study evaluated racial disparities in self-reported adverse events based on cross-sectional survey data collected as part of a national, prospective cohort evaluating stroke mortality. Findings show that Black participants were significantly more likely to report a preventable adverse event attributable to poor care coordination (e.g., drug-drug interaction, emergency department visitor, or hospitalization) compared to White participants.

Based on the Safer Dx and SPADE frameworks, researchers applied a symptom-disease pair-based electronic trigger (e-trigger) to identify patients hospitalized for stroke who had been previously discharged from the emergency department with a diagnosis of headache or dizziness in the preceding 30 days. Analyses show that the e-trigger identified missed diagnoses of stroke with a modest positive predictive value.

A missed or delayed diagnosis of stroke increases the risk of permanent disability or death. This retrospective study compared rates of misdiagnosed stroke in patients presenting to general care or specialty care who were initially diagnosed with “benign dizziness”. Patients with dizziness who presented to general care were more likely to be misdiagnosed than those presenting to specialty care. Interventions to improve stroke diagnosis in emergency departments may also be successful in general care clinics.

Alteplase and other thrombolytics are high-alert medications. This study compared error rates of alteplase administration in patients presenting with acute ischemic stroke at either a regional hospital or a Comprehensive Stroke Center (CSC) and found that community hospitals had over a 10 times greater number of errors leading to hemorrhage. The study recommend to put safeguards in place to decrease the risk of alteplase medication administration errors.

The ”weekend effect” refers to worse patient outcomes occurring outside of usual business hours. The authors used national data to examine in-hospital mortality differences among patients experiencing stroke admitted on the weekend versus on a weekday. After adjusting for patient and hospital characteristics, in-hospital mortality among hemorrhagic stroke patients was significantly greater among weekend compared to weekday admissions. No weekend effect was found among ischemic stroke patients. Future research should explore the influence of additional factors, such as patient-level behavioral risk factors and the availability of care providers and stroke care centers, particularly in rural regions.
