Exploring emergency department providers' uncertainty in neurological clinical reasoning.

Abstract

Objectives: Diagnostic and management reasoning of neurological disorders may present unique challenges and uncertainty for clinicians, particularly in emergency department settings. This study aims to assess the level of uncertainty emergency department physicians experience when diagnosing neurological versus non-neurological conditions, and whether this uncertainty extends to the management of neurological conditions. Additionally, the study explores whether clinical experience is related to perceived diagnostic and/or management uncertainty.

Methods: Fifty-three emergency department physicians completed a survey measuring diagnostic uncertainty, management uncertainty, and associated anxiety. The survey included clinical vignettes depicting neurological and non-neurological cases, as well as items which assessed perceived diagnostic and management uncertainty across eight different specialties. Statistical analyses included paired samples t-test for comparing uncertainty between neurology and non-neurology cases and a general linear model to assess relationship between clinical experience and uncertainty.

Results: Emergency department physicians reported greater diagnostic uncertainty for neurological vignettes compared to non-neurological vignettes (Cohen's d=1.37), as well as greater management uncertainty (Cohen's d=1.41). They also reported greater anxiety when diagnosing neurological cases compared to non-neurological cases (Cohen's d=1.33), as well as greater anxiety when managing them (Cohen's d=0.69). Exploratory analyses indicated that with greater experience, management uncertainty of neurology cases decreased, while diagnostic uncertainty remained unchanged.

Conclusions: The results suggest unique diagnostic and management challenges posed by neurological cases in emergency departments, particularly for less experienced providers. Future research could focus on developing interventions to reduce diagnostic and management uncertainty in neurological conditions.
