What is the treatment for factitious disorder imposed on another (Munchausen syndrome by proxy)?

Treatment of Factitious Disorder Imposed on Another (FDIA)

The treatment of factitious disorder imposed on another (FDIA) requires immediate separation of the perpetrator from the victim to ensure the victim's safety, followed by a multidisciplinary approach involving child protective services, law enforcement, mental health professionals, and medical providers. 1

Initial Management and Safety Measures

• The first priority in managing FDIA is ensuring the victim's safety through separation from the perpetrator, which is essential to prevent ongoing harm and confirm the diagnosis by observing symptom resolution 2, 3
• Healthcare providers must report suspected cases to appropriate authorities (child protective services for child victims or adult protective services for vulnerable adults) as FDIA is considered a form of abuse 3, 4
• Hospitalization of the victim may be necessary during the initial evaluation phase to monitor symptoms in a controlled environment and document their resolution when separated from the perpetrator 5, 6

Diagnostic Approach

• Diagnosis requires careful documentation of inconsistencies between reported symptoms and objective findings, with consideration of multiple sources of information 1, 3
• Video surveillance may be necessary in some cases to document the perpetrator's behavior, though this requires appropriate ethical and legal considerations 3
• Medical records from multiple facilities should be obtained, as perpetrators often engage in "doctor shopping" and have extensive healthcare utilization patterns 6, 4

Treatment of the Perpetrator

• Psychiatric evaluation and treatment of the perpetrator is essential, focusing on underlying psychopathology that may include personality disorders, depression, or anxiety 3
• Individual psychotherapy for the perpetrator should address psychological needs that drive the abusive behavior, including attention-seeking, identity issues, and need for control 3, 4
• Cognitive-behavioral therapy approaches may help address distorted thinking patterns and maladaptive behaviors 3
• Medication may be indicated for comorbid psychiatric conditions such as depression or anxiety disorders 3

Treatment of the Victim

• Medical treatment should focus on addressing any genuine medical conditions and discontinuing unnecessary treatments or medications 2
• Age-appropriate psychotherapy for the victim is crucial to address trauma, confusion about their health status, and potential development of factitious behaviors 5, 3
• Family therapy may be appropriate in select cases, but only after thorough evaluation and when deemed safe for the victim 3
• Long-term monitoring of the victim's physical and psychological health is necessary due to the risk of long-term effects of medical trauma 3

Multidisciplinary Coordination

• A coordinated approach involving healthcare providers, mental health professionals, child/adult protective services, and legal authorities is essential 3, 4
• Clear communication between all involved professionals helps prevent the perpetrator from manipulating different providers or systems 3
• Designated case coordinators can help manage the complex interplay between medical, psychological, and legal aspects of these cases 3

Common Pitfalls and Challenges

• Delayed recognition is common due to the deceptive nature of the disorder and the perpetrator's often convincing presentation 6, 4
• Healthcare providers may inadvertently become complicit in the abuse by performing unnecessary tests and treatments 2, 4
• Confronting the perpetrator directly without proper preparation and support systems in place can lead to escalation of abuse or flight to another healthcare system 3
• Ethical dilemmas regarding confidentiality, use of surveillance, and balancing the rights of the perpetrator with the safety of the victim require careful consideration 3

Long-term Management

• Reunification of the victim with the perpetrator should only be considered after extensive treatment of the perpetrator and with ongoing close monitoring 3
• In many cases, permanent separation may be necessary to ensure the victim's safety 3
• Regular follow-up with both victim and perpetrator is essential to monitor for recurrence of factitious behavior 3, 4
• Education of healthcare providers about FDIA is crucial to improve early recognition and appropriate intervention 6, 3
