Refer a Patient With Congenital Hyperinsulinism (HI)

How do I refer?

Contact the Congenital Hyperinsulinism Center by phone or online.

  • If the patient may need surgery, it is useful to send a specimen to a specialty genetic reference lab for mutation analysis as early as possible, since results may take more than two weeks.
  • Initiate precertification from the insurance company (allow a minimum of 72 hours to complete). We can advise and assist you as needed.

When should I refer?

We invite you to contact us at any point in your patient evaluation process to discuss options or to seek advice on patient management. We serve as a resource for physicians and families, providing information to gauge when a child can be diagnosed and managed at their local institution, and when the condition requires a visit to CHOP. Once a patient fails a trial of diazoxide therapy, it is usually an appropriate time to consider a transfer to Children’s Hospital.

What happens after I refer?

After a child has failed treatment with diazoxide, we usually start octreotide. If the child continues to have low blood sugar with medical therapy, we consider surgery to remove part of the pancreas. First, the child may undergo additional testing to determine if the HI is focal or diffuse, as surgical management depends on the patient’s type of hyperinsulinism: diffuse HI requires a 98 percent pancreatectomy, and focal HI requires a resection of the affected part of the pancreas only. 18F-DOPA imaging allows us to determine the nature of the disease.

Children’s Hospital works with referring physicians before transport and maintains close communication and collaboration after the patients return home.
