How do Physicians Manage Functional Neurological Symptom Disorder and Somatic Symptom Disorder in the Emergency Department? A Vignette Study.

Abstract

Introduction:We aimed to explore how physicians from different specialties approach the management of functional neurological symptom (conversion) and somatic symptom disorders in the emergency department compared with pulmonary embolism and how physicians’ professional and personal characteristics influence their diagnostic preferences.Methods:Using a vignette methodology, and cross-sectional design, three emergency department case vignettes of possible functional neurological symptom, somatic symptom disorder, and pulmonary embolism were presented to physicians from internal medicine, emergency medicine, and psychiatry. A structured survey including questions on diagnosis and management of these cases, and physicians’ professional and personal characteristics (childhood trauma, attachment style) was conducted.Results:Physicians from internal medicine and emergency medicine tended to consider functional neurological symptom disorder as ‘malingering’ while psychiatrists tended to diagnose the pulmonary embolism case as a psychiatric condition. Emergency medicine physicians preferred to manage functional neurological symptom disorder themselves, while other doctors endorsed recommending a psychiatric consultation. In the univariable model, being a physician from psychiatry, emergency medicine, or internal medicine; being a specialist, history of childhood sexual abuse, dismissive, and fearful attachment styles of doctors were significant predictors of diagnosing functional neurological symptom disorder as malingering. Being a psychiatrist stayed as the only significant predictor in the multivariable model.Conclusion:Objectively-aberrant functional neurological symptoms and subjective somatic symptoms may be creating different reactions in physicians. In the emergency department, physicians’ diagnostic and treatment preferences of conversion disorder may be influenced by lack of training in conversion disorder, rather than their personal characteristics.
