Factitious disorder — Clinical Guidelines

Overview

Factitious disorders involve patients intentionally fabricating or inducing physical or psychological symptoms to assume the role of a patient, often leading to unnecessary medical investigations and interventions 1 3.

Diagnosis

Clinical Presentation: Recurrent feigning of symptoms, often involving multiple organ systems (e.g., factitious purpura, haematuria, bacteremia) 4 6 11.

Differential Diagnosis: Distinguish from genuine medical conditions through thorough history, physical examination, and targeted investigations (e.g., ruling out organic causes through biopsies, imaging) 4 6.

Psychological Evaluation: Consider psychiatric assessment to explore underlying motives and psychological dynamics 7 8.

Documentation: Look for inconsistencies in patient history and repeated hospitalizations 3 5.

Management

Psychotherapy: Cognitive-behavioral therapy (CBT) and psychodynamic therapy are recommended to address underlying psychological issues 9 14.

Psychiatric Referral: Essential for comprehensive mental health evaluation and treatment 7 14.

Multidisciplinary Approach: Collaboration between healthcare providers, psychiatrists, and social workers to manage complex cases 8.

Education: Inform healthcare teams about the condition to prevent misdiagnosis and inappropriate treatment 1.

Special Populations

Pediatrics: Recognition of factitious symptoms taught by caregivers (e.g., mother teaching child to feign illness) 5.

Pregnancy and Gynecology: Increased awareness needed due to rising cases in obstetrics and gynecology 3.

Comorbidities: Consider overlap with deliberate self-harm and substance abuse issues 7 8.

Key Recommendations

Conduct thorough differential diagnosis including psychological evaluation to confirm factitious disorder (Evidence: Moderate 7 9).

Implement a multidisciplinary approach involving psychiatric care and psychotherapy to address underlying psychological issues (Evidence: Moderate 9 14).

Enhance healthcare provider education on recognizing and managing factitious disorders to minimize misdiagnosis and unnecessary interventions (Evidence: Expert opinion 1).
