Clinical trials to demonstrate telehealth on reservations

March 18, 2002 Share This!

RICHLAND, Wash. – Pregnant women living on South Dakota Indian reservations where infant mortality rates are more than twice the national average will receive specialty care under the first commercial test of a telehealth system called MUSTPAC-3 (for the third version of the Medical Ultrasound, Three-dimensional and Portable with Advanced Communications).

This state-of-the-art portable ultrasound system was developed at the Department of Energy's Pacific Northwest National Laboratory. Avera McKennan Hospital & University Health Center in Sioux Falls, SD, received a grant from the Department of Agriculture Rural Utility Service to determine if telehealth could improve treatment of pregnant women.

Through this grant, PNNL researchers have installed MUSTPAC-3 on two Indian reservations in South Dakota and trained healthcare providers to use them. The MUSTPAC systems will be deployed at clinics operated by Indian Health Service, which works with Avera McKennan, to provide healthcare to women who live in the reservation communities of Pine Ridge and Rosebud.

Healthcare providers at these clinics will use MUSTPAC-3 to monitor 100 women who are in their first trimester of pregnancy. Information obtained through these studies will be used in the FDA approval process for
MUSTPAC-3.

"The ideal result of this study would be reduced fetal and newborn mortality through better treatment for women earlier in the pregnancy," said Deb Soholt, director of women's health for Avera McKennan. "Telemedicine may be the best method for accomplishing that. We're hopeful the FDA will approve MUSTPAC-3 for commercial use."

Pregnant women on these reservations have limited access to specialists, which often means problems aren't detected until late in the pregnancy when treatment is more difficult, costly or complicated. Pine Ridge and Rosebud had mean infant mortality rates considerably higher than the United States' latest rate of 8.5 per 1,000 live births from 1990-1994, with rates of 25.1 and 18.5 respectively.

MUSTPAC-3 stations will be deployed at the reservations' clinics for data acquisition while a station will be installed at Avera McKennan in Sioux Falls for diagnosis.

"Our system requires little training and is easy to operate," said Laura Curtis, PNNL project manager. "A nurse with limited training can use a probe to scan a woman's lower abdomen, then transmit the images to a specialist by telephone line. A specialist can make a diagnosis using these 3D images even if the patient is hundreds of miles away."

Pine Ridge and Rosebud are 350 and 240 miles respectively from Sioux Falls, which houses the state's only perinatologists, or obstetricians with special training in high-risk pregnancies.

MUSTPAC-3 research principal investigator, Dr. Gary Helmbrecht from Avera McKennan Maternal Fetal Medicine says, "It is truly exciting to be a leader in bringing cutting-edge technology to rural areas. PNNL's technology allows us to reach patients who might not otherwise have access to tertiary services."

Interdisciplinary teams at Pacific Northwest National Laboratory address many of America's most pressing issues in energy, the environment and national security through advances in basic and applied science. Founded in 1965, PNNL employs 4,300 staff and has an annual budget of about $950 million. It is managed by Battelle for the U.S. Department of Energy’s Office of Science. As the single largest supporter of basic research in the physical sciences in the United States, the Office of Science is working to address some of the most pressing challenges of our time.
