Hospital costs for children with flu may be higher th...( Going into another flu season a new s...),Health

Going into another flu season, a new study reports that hospitalizing children for influenza may cost up to three or four times the previously accepted estimates. Pediatric researchers from The Children's Hospital of Philadelphia say their finding strengthens the economic justification for broadly vaccinating children against flu.

"We found the cost of influenza-related hospitalizations in children was about $13,000 each--compared to most prior studies that estimated the cost at three to four thousand dollars," said study leader Ron Keren, M.D., M.P.H., a pediatrician at The Children's Hospital of Philadelphia. "This suggests that annual influenza vaccinations for children, especially for those with certain high-risk conditions, may be more cost-effective than previously thought."

The study appears in the November issue of Pediatrics.

The researchers analyzed billing data for 727 patients up to age 21 who were admitted to Children's Hospital with laboratory-confirmed influenza over four consecutive flu seasons, from 2000 to 2004. The study team statistically adjusted the direct medical costs to account for geographic variations in those costs.

"We found a broad range of hospital costs in the study, from approximately $7,000 each for patients treated only on the ward, to nearly $40,000 each for children cared for in the intensive care unit," said Dr. Keren. Children with low-risk conditions had hospital costs averaging $9,000 each, compared to those with high-risk conditions, whose costs averaged $15,000 each.

The study team used risk categories defined by the American Committee on Immunization Practices (ACIP), which has designated medically vulnerable patients who should receive influenza vaccinations. For instance, high-risk conditions include children with heart disease, chronic lung disease, asthma, and disorders of hemoglobin such as sickle-cell disease.
