New study on childhood asthma shows home-based interventions are cost-effective

13.10.2005


New data suggest that a home-based environmental intervention program is a cost-effective way to improve the health of inner-city children who have moderate to severe asthma. The program successfully decreased allergen levels in the home and reduced asthma symptoms. The data also show that the cost would be substantially lower if the interventions were implemented in a community setting, and that they would be as cost-effective as many drug interventions.



The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), provided major funding to researchers at seven centers across the United States for the two-year study. The National Institute of Environmental Health Sciences (NIEHS), part of NIH, also supported the research. Study results are now available online in the Journal of Allergy and Clinical Immunology.

"While the interventions were clearly effective in reducing asthma symptoms, we wanted to know whether the measures were cost-effective," says Meyer Kattan, M.D., a pediatric pulmonologist with the Mount Sinai School of Medicine and lead author on the study.


The home-based program was designed to target six major classes of allergens that trigger asthma symptoms--dust mites, cockroaches, pet dander, rodents, passive smoking and mold. The environmental interventions were tailored to each child’s sensitivity to the selected allergens and evidence of exposure to these asthma triggers.

Those enrolled in the program received educational home visits that included specific measures for reducing or eliminating allergen levels inside the home. These included allergen-impermeable covers on the child’s mattress, box spring and pillows; air purifiers with high efficiency particulate air (HEPA) filters; vacuum cleaners equipped with HEPA filters; and professional pest control.

The home-based interventions resulted in significant improvement in health status and reductions in resource use among the asthmatic children. Children who received the intervention had 19 percent fewer unscheduled clinic visits and a 13 percent reduction in the use of albuterol inhalers, small applicators that deliver asthma medication directly into the lungs. Children in the intervention group experienced 38 more symptom-free days over the two-year course of the study than those in the control group.

"These results show that tailored interventions such as these may have a substantial long-term impact on asthma symptoms and resource use among inner-city children," says NIEHS Director David A. Schwartz, M.D. "They may be particularly beneficial for asthmatic children who are exposed to multiple allergens and lack the proper access to quality health care."

To evaluate the cost-effectiveness of the program, the researchers calculated the direct costs of the services provided to each child, along with an estimate of the symptom-free days gained as a result of the interventions. "The asthma intervention resulted in an average increase of 37.8 symptom-free days over the two-year period, at an estimated cost of $27.57 per symptom-free day," says Dr. Kattan.

"The findings of this study will enable policy makers and health care providers to more effectively allocate resources to achieve maximum benefits," says Peter J. Gergen, M.D., M.P.H, of NIAID’s Division of Allergy, Immunology and Transplantation, an author on the paper.

The study is part of the larger Inner-City Asthma Study, a multicenter project created to evaluate the effectiveness of environmental interventions on asthma incidence. The study participants included more than 900 children, ages 5 to 11, with moderate to severe asthma.

Most of the children were African American or Hispanic, living in low-income sections of seven urban areas--the Bronx, Boston, Chicago, Dallas, Manhattan, Seattle/Tacoma and Tucson. Each child had to be allergic to at least one common indoor allergen, such as cockroach or house dust mite allergen.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
