Cost variation rampant in children's hospitals for treating asthma, JAMA Pediatrics study shows
Research team analyzed data from nearly 49,000 children hospitalized for asthma at 37 major nonprofit children's hospitals from 2011 to 2014.
Patient costs for treating asthma vary greatly in children's hospitals, according to researchers who analyzed hospital records in a large national database. Even when patients were grouped by characteristics such as age or severity of illness, hospitals differed significantly in inpatient costs, length of stay, and time spent in the intensive care unit.
Lead author of the new study, Jeffrey Silber, M.D., Ph.D., director of the Center for Outcomes Research at The Children's Hospital of Philadelphia, said in a statement that asthma imposes a major financial burden on many healthcare systems.
"If hospitals can better understand if their care practices are disproportionately expensive and inefficient compared to other hospitals, they may be better able to pinpoint opportunities for quality improvements," he said.

Silber and colleagues from CHOP and the Perelman School of Medicine at the University of Pennsylvania co-authored the study, which appeared in JAMA Pediatrics.
The research team analyzed data from nearly 49,000 children hospitalized for asthma at 37 major nonprofit children's hospitals in the Pediatric Health Information dataset. All the children were hospitalized during 2011 to 2014.
The researchers found that for patients with a similar set of characteristics, median cost varied by 87 percent, total length of stay varied by 47 percent, and ICU usage was 254 percent higher, all when comparing the lower eighth to the upper eighth of hospitals.

In addition, patterns of resource use differed significantly across hospitals when classified by patient risk. In some hospitals, costs for higher-risk patients were significantly higher compared to matched controls, while in other hospitals, those costs decreased as patient risk increased.
The study team used a new analytical tool they developed called "template matching." That tool grouped patients by different characteristics to create templates that could be compared to matched patient templates derived from each hospital. This matching system, said Silber, allows hospitals to audit their costs and resource use in a more refined way than simply reporting if there is more or less expensive treatment in an aggregate fashion for a given diagnosis.

In an online editorial in JAMA Pediatrics commenting on the study, Dr. Jay Berry of Boston Children's Hospital said that Silber and colleagues "devised a way to systematically match and compare apples with other apples and then oranges with other oranges."
"Although there are well-established clinical pathways for treating children with asthma, we found significant differences in how tertiary-care pediatric hospitals used their resources," said Silber. "However, this auditing method offers hospitals some guidance in identifying practice styles that could improve their care."
