Pediatric atlas marks a return to the roots of variations research

By Nancy Fontaine

David Goodman's newest research project is, in some ways, a return to the past.

In the 1960s, John Wennberg uncovered wide variations in rates of tonsillectomy in Vermont, sparking his interest in the study of health-care delivery and leading, eventually, to the creation of the Dartmouth Atlas Project in the 1990s.

Goodman, a pediatrician by training and the director of the Center for Health Policy Research at TDI, began working on the Atlas at its inception, and his earliest research interest was in pediatric care in northern New England. But databases to support such research were limited, so he moved on to other areas, such as the study of variations in physician supply.

Now, as co-principal investigator of the Dartmouth Atlas Project, Goodman is returning to his interest in variations in pediatric care thanks to the availability of new datasets and the support of the Hood Foundation. "I'm excited to get back to pediatric studies with an interesting and powerful dataset," he says. "It's the ideal utilization dataset for a region and sets the benchmark for the nation."

The northern New England dataset—which currently includes Maine, New Hampshire, and Vermont and will add Massachusetts in the near future—is unusual in that it includes data from both Medicaid and commercial insurers. The collection of the commercial data was mandated by the states. When federal Medicaid data is included, the research can be performed on what Goodman refers to as "all-payer data sets."

Unlike the study of the elderly . . . there's been little work in pediatrics.

The work is being funded by a grant from the Hood Foundation, which has a history of funding research on pediatric diseases. The Foundation has strong ties to Dartmouth, having funded both the Hood Center for Children and Families and the Hood Museum of Art at Dartmouth. "The Foundation has become very interested in the work we do at the Dartmouth Institute," says Goodman.

The project has three main goals. The first is to develop an atlas of pediatric health care in northern New England. Goodman hopes that this work will encourage further research in pediatric care and convince states to support the gathering of data on pediatric care. "The states need to mandate this type of data collection if we are to understand the care paid for by commercial payers," he explains. The Atlas work is nearly complete and is projected to be published later this year.

The second goal is to publish peer-reviewed research. Goodman and his colleagues are developing unique studies of prescribing patterns for children and of the care of medically complex children at children's hospitals. "Medically complex children are an important group of patients who are also terrifically expensive, and there's been little work to understand how these kids are cared for," says Goodman. The studies aim to demonstrate what works best and how to improve care generally.

The third goal is to convene the very small community of researchers who are studying variations in pediatric health care. "Unlike the study of the elderly, where there is a large, robust community, there's been little work in pediatrics," Goodman says. "In December 2013, we're going to bring together those researchers to see if we can advance the research."

The final Atlas measures will include those for evidence-based care, selected surgical procedures (including tonsillectomies), hospitalizations, imaging, emergency room use, and prescription drug use.

When the research is complete, both Goodman and variations research at Dartmouth will have come full circle, revisiting Wennberg's earliest work 40 years after it was started.
