What kind of doctor treats Munchausen Syndrome By Proxy?
Care for a child with Munchausen syndrome by proxy may start with a pediatrician, a doctor who cares for children. Care may involve a team that includes social service workers. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is Munchausen syndrome by proxy?
Munchausen syndrome by proxy is a form of child abuse. It involves both physical abuse and medical neglect.
It happens in the medical setting. A parent or caregiver causes injury to a child by seeking or giving medical treatment that is not needed and may be harmful.
It has also been described as making another person sick on purpose, usually a child. The caregiver does this to take on the sick role through the child. This is what "by proxy" means.
The condition is rare. It is also poorly understood, and it is a controversial diagnosis.
Some doctors use a newer name: fabricated or induced illness by carers. A group of children's doctors, the Royal College of Paediatrics and Child Health, suggested it. The new name puts the focus on child abuse in the medical setting.
Symptoms
Doctors need to think about this condition when a child has findings that cannot be explained, or when treatments keep failing.
The child may get medical care that is not needed and that is harmful or could be harmful. Care can become abusive when a caregiver keeps making up symptoms or lying about them. It can also become abusive when a caregiver tampers with lab tests. A caregiver may also harm the child on purpose to create symptoms.
These cases often go undiagnosed. This can lead to many unneeded tests and hospital stays. It can also lead to serious illness and even death.
Causes and who gets it
The condition is poorly understood. Doctors describe it as an intentional act by the caregiver.
The caregiver is most often the mother. Fathers have also been reported. The children affected are usually under 6 years of age.
How doctors diagnose it
Doctors are advised to ask three questions:
- Are the history, signs, and symptoms of disease credible (believable)?
- Is the child getting medical care that is not needed and that is harmful or could be harmful?
- If so, who is instigating the evaluations and treatment?
To find out whether symptoms were made up, doctors gather facts from everyone involved. They share concerns with other health care workers and social service workers.
A thorough review of medical charts is important. So is clear communication among medical professionals.
Doctors should think about this condition along with their first diagnosis. They should not wait until every other cause has been ruled out.
Treatment
Care of an abused child may involve a team. The team can include primary care doctors, specialists, dietitians, physical therapists, and social service workers.
Treatment includes making sure the child is safe in the future. It also includes allowing treatment to take place in the least restrictive setting possible.
The state child protective services agency should be told if the caregiver is harming the child. This applies when the caregiver will not work with the child's doctor to limit medical care. Medical child abuse should be reported in the same way as physical and sexual child abuse if the caregiver continues to harm the child.
Child protection services and legal services may also be involved. It depends on how severe the case is.
Treatment is very difficult. Early recognition can prevent possible harm to the child.
When to see a doctor
The state child protective services agency should be informed if a parent or caregiver is harming a child.
Call 911 if a child has trouble breathing, a seizure, unstoppable bleeding, or loss of consciousness.
If you are thinking about harming yourself, call or text 988 (the Suicide and Crisis Lifeline) right away.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. A direct primary care doctor can review your child's records, follow your child's health over time, and help coordinate specialists.
