What is a pediatric hospitalist?

A pediatric hospitalist is a pediatric healthcare provider who works exclusively in the hospital.

Locally well-known and respected pediatric hospitalist, James Matsuda, MD, PhD, joined Mercy in October 2013. Dr. Matsuda has received additional medical training, including a fellowship in pediatric critical care medicine with the University of Iowa Children’s Hospital to provide specialized pediatric care.

What does a pediatric hospitalist do?

Dr. Matsuda and Sara care for babies and children who were admitted to Mercy after surgery, an emergency, or for any other reason.

Dr. Matsuda coordinates a variety of services for hospitalized children, including:

  • Leading and managing your child’s care while he or she is in the hospital
  • Performing physical examinations
  • Ordering tests and procedures
  • Prescribing medications
  • Referring patients to specialty physicians, if necessary
  • Communicating with the child’s primary provider

Can my child’s pediatrician or family provider see my child in the hospital?

Some pediatricians and family providers will come to the hospital to care for their own patients. However, because physician practices are becoming busier and hospital technology is advancing rapidly, primary physicians are increasingly enlisting the help of a hospitalist to care for patients at the hospital.

Additionally, hospitalists like Dr. Matsuda provide an even higher quality of care to patients because of their greater specialized experience with critical or intensive care cases.

Will my pediatrician or family provider be updated on my child’s condition?

Yes. While Dr. Matsuda will be highly engaged in your medical care, your primary physician will be continuously updated on your child’s admission, discharge or any changes in your health during your stay at Mercy.
